Chapter 1
General Introduction1.1
In their professional, educational, and social lives, people often encounter a multitude of
demanding commitments. At the workplace, people may have an impatient boss on their back to
ensure fast job completion while adhering to high product standards. Educational environments
often press students to manage complex working schedules under compelling time constraints.
People also have to live up to various social expectations such as visiting a sick family member,
organizing an important neighborhood meeting, or settling a dispute between two friends.
Managing such everyday demands is not without costs. Meeting high demands can drain people’s
energy, make them more forgetful and less accurate, and leave them sulky and frustrated. In severe
cases, high demands may cause stress and even serious health problems (Lazarus & Folkman, 1984;
Segerstrom & Miller, 2004). It is therefore important to learn how people can effectively cope with
demanding situations (Hockey, 1997; Schönpflug, 1983; Zeidner & Endler, 1996).
In the present dissertation, I examine the role of action control in coping with high demands.
Action control refers to the mental processes that allow people to form, maintain, and implement (or
disengage from) their intentions (Kuhl & Goschke, 1994a). Building on Personality Systems
Interactions (PSI) theory (Kuhl, 2000, 2001), I suggest that efficient action control allows people to
cope more effectively with demanding situations. Efficient action control skills should therefore
constitute a key moderator of how people cope with demanding situations. Individuals who are
more skilled at action control, or action-oriented individuals, can be expected to function more
optimally under high demands compared to individuals who are less skilled at action control, or
state-oriented individuals. Indeed, this dissertation will try to show that, under demanding
conditions, action-oriented individuals display better working memory, more efficient affect
regulation, and more efficient implementation of difficult intentions relative to state-oriented
individuals. In the remainder of this introductory chapter, I discuss a theoretical analysis of action

control and performance under high demands. Next, I provide an overview of the remaining
chapters of the dissertation, which report empirical tests of this analysis.
On the Regulation of Action
High demands usually emerge when people attempt to prepare or enact some form of action.
In order to understand the dynamics of high demands, it is therefore useful to first examine the
workings of human action. To a large extent, human action is based on routines and guided by
automatic processes outside the realm of conscious awareness (Bargh, 1994).1.2 In the last twenty
years or so, experimental social psychologists have demonstrated that the automaticity of action
extends beyond inborn reflexes and overlearned motor programs to complex and meaningful
behavior (for reviews, see Bargh & Chartrand, 1999; Ferguson & Bargh, 2004). A central
conclusion in this research is that people can automatically initiate behavioral responses to the mere
perception of a relevant stimulus. For instance, merely encountering positive or negative stimuli can
automatically elicit affective responses such as mood changes (Chartrand, Van Baaren, & Bargh,
2006) evaluations (Fazio, Sanbonmatsu, Powell, & Kardes, 1986) or approach and avoidance
tendencies (cf. Gray, 2001; Neumann, Förster, & Strack, 2003).
Automatic processes may allow people to function relatively efficiently and without much
conscious effort. However, in some situations, people may need to override automatically activated
responses. For instance, after a doctor’s visit, a person may adopt the goal to quit smoking. In these
or similar cases, people experience a conflict between an automatized (e.g., smoking after dinner)
and an intended response (e.g., eating some fruit instead). To resolve such conflict, people need to
exert cognitive control over their responses (Posner & Snyder, 1975; cf. Norman & Shallice, 1986;
Schneider & Shiffrin, 1977).1.3
Cognitive control refers to a process whereby people can override strong but inappropriate
response tendencies. As such, cognitive control can be considered a non-automatic way of
responding that increases people’s behavioral flexibility when automaticity proves too rigid. In
When The Going Gets Tough… 7
social psychology, cognitive control processes have thus far received relatively little attention (but
for exceptions, see Bayer, Ferguson, & Gollwitzer, 2003; Mischel, Cantor, & Feldman, 1996).
Moreover, to the extent that social psychologists have studied cognitive control, they have been
mostly interested in the failure of cognitive control (Baumeister, Heatherton, & Tice, 1994) or in
situations in which control is illusory (Wegner, 2002). In other areas of psychology, however,
cognitive control has been extensively examined. For instance, the study of cognitive control is a
key issue in cognitive psychology (Gray, 2001), cognitive neuroscience (Ridderinkhof, Ullsperger,
Crone, & Nieuwenhuis, 2004), developmental psychology (Nigg, 2001), and clinical psychology
(Cohen, Braver, & O’Reilly, 1998).
A classic paradigm that has been used to study cognitive control processes is the so-called
Stroop task (Stroop, 1935; for a review see MacLeod, 1991). In a typical version of the task,
participants are asked to name the ink color in which a target (i.e., a word or a meaningless letter
string) is displayed. Participants are further instructed to ignore any meaning of the target words.
Task performance generally becomes more difficult when the meaning of a word refers to a color
that is incongruent with the ink color (e.g., RED displayed in blue) compared to when word
meaning and ink color are congruent (e.g., RED displayed in red), or when the target is a neutral
letter string (e.g., XXXX displayed in blue). A likely reason is that reading the word meaning is a
highly automatic action tendency that conflicts with the task instructions to concentrate on the ink
color. Failure to control the automatic reading impulse leads to increased error rates and slower
responses on incongruent compared to congruent or neutral targets. The amount of such “Stroop
interference” can be regarded as an indicator of how well participants were able to exert cognitive
control.
Intentional Action Control
Recent research suggests that success at cognitive control depends on two separate factors
(De Jong, Berendsen & Cools, 1999; Kane & Engle, 2003). The first factor pertains to the mere
When The Going Gets Tough… 8
capability to inhibit an undesired impulse. For the ex-smoker, for instance, the critical question is
whether s/he is able to suppress the urge to lighten a cigarette when s/he feels the craving for
nicotine (cf. Tiffany, 1990). A second but related problem is whether the person is able to fully
bring his or her inhibitory capabilities to bear in a given situation (Duncan, 1995). For the ex-
smoker, the critical question is whether s/he has really committed him- or herself to quit smoking
and whether this decision becomes sufficiently accessible when the craving arises. To fully utilize
their inhibitory capabilities, people thus first need to form and actively maintain an internal
representation of how to respond in a critical situation. In other words, people need to form and
maintain an intention.
Intentions can be seen as arrangements that people make with themselves about what to do
in a particular situation. According to traditional views in social psychology, people form intentions
to enact a particular behavior when they think that it is desirable to perform the behavior and when
they think that it is feasible to do (Ajzen, 1988; Fishbein & Ajzen, 1975). This traditional view is
limited for at least two reasons. First, people may form intentions even when the perceived
feasibility of the anticipated action is low (cf. Shah & Higgins, 1997), or people may not form
appropriate intentions even when the perceived feasibility and desirability of an action are high (cf.
Gollwitzer, 1993). Second, and more important in the present context, traditional views have
remained silent about the processes that translate intentions, once they have been formed, into
action (cf. Eagly & Chaiken, 1993). Understanding these processes is important, however, because
people are not always able to implement their intentions successfully.
The psychological processes that lead to the formation and implementation of intentions (or
to its disengagement) have been subsumed under the term action control (cf. Gollwitzer, 1996,
1999; Kuhl, 1984; Kuhl & Goschke, 1994a). According to theories of action control, intentions are
mental representations of action plans that cannot be enacted immediately but have to be postponed
until a future moment. In contrast with merely wishing to exert some action, intentions imply that a
When The Going Gets Tough… 9
person has committed him- or herself to actually do it (“I really will do it”). After an intention has
been formed, it may persist in an implicit format outside of conscious awareness until it
automatically becomes reactivated when appropriate situational cues have been encountered (cf.
Gollwitzer, 1993; Goschke & Kuhl, 1996; Martin, Kliegel, & McDonald, 2003). However, when
the intended action is complex, difficult, or must not be forgotten, intentions remain represented in
an explicit state that consumes attention (cf. Anderson, 1983). The psychological system that
maintains explicit representations of intentions activated in memory has been referred to as
intention memory (Kazén & Kuhl, 2005; Kuhl & Kazén, 1999).
Explicit intentions have preferred access to consciousness compared to non-intention-related
information (cf. Zeigarnik, 1927). Evidence for such an “intention superiority effect” comes from a
series of studies, in which participants had to learn short scripts of activities (e.g., setting a table)
that were moderately complex because they included several substeps (e.g., distribute the cutlery)
(Goschke & Kuhl, 1993; cf. Marsh, Hicks, & Bink, 1998). After the learning phase, participants
were informed that they would have to execute one of the scripts later during the experiment. In a
subsequent word recognition task, participants had to indicate whether a word belonged to any of
the scripts. Reflecting the intention superiority effect, participants were found to be faster in
recognizing words from the to-be-executed script compared to words from scripts that did not have
to be executed. These findings support the notion that intention memory plays an important role in
the regulation of action (cf. De Jong et al., 1999; Kane & Engle, 2003).
Working Memory
Intention memory is part of a greater system of memory processes that are commonly
referred to as working memory (Baddeley, 1986; Baddeley & Hitch, 1974; Engle, Kane, &
Tuholski, 1999; cf. Miyake & Shah, 1999; see Kazén & Kuhl, 2005, on the subtle functional
differences between intention memory and working memory). The main task of working memory is
the on-line maintenance and manipulation of explicit information in the service of planning,
When The Going Gets Tough… 10
complex reasoning, and intentional action. This task includes storage components and attentional
processes. Due to capacity constraints, working memory can only process a limited amount of
information at a time (cf. Neumann, 1987; Pashler, 1994). To use its limited capacity efficiently,
working memory has to be frequently updated such that irrelevant information becomes erased,
relevant information becomes maintained and new information that may be potentially relevant,
gains access to working memory. How exactly working memory updates its contents has not yet
been fully understood. However, there is widespread agreement that updating of working memory
relies on the availability of positive affect and its neurobiological substrate dopamine (cf. Braver &
Cohen, 2000; Cohen, Braver, & Brown, 2002; Dreisbach & Goschke, 2004; Dreisbach et al., 2005;
Kuhl, 2000).
A classic way to measure working memory capacity is the operation span (OSPAN) task
(Turner & Engle, 1989; cf. La Pointe & Engle, 1990). In the OSPAN task, participants are required
to calculate simple arithmetic equations while retaining short series of words in memory for later
recall. Working memory capacity is reflected by a person’s span, i.e. the number of words that can
be recalled correctly while performing the calculations. Using various kinds of span tasks (e.g.,
Daneman & Carpenter, 1980), research has shown that there exist substantial individual differences
in working memory capacity (for a review, see Feldman Barrett, Tugade, & Engle, 2004). Relative
to individuals with small working memory capacity, individuals with large working memory
capacity display greater resistance to distraction (Conway, Cowan, & Bunting, 2001), better
academic achievement (Gathercole & Pickering, 2000), and higher general fluid intelligence
(Engle, Tuholski, Laughlin, & Conway, 1999).
A recent set of studies indicates that working memory capacity contributes to cognitive
control. In these studies, the researchers examined Stroop interference among individuals with high
versus low working memory capacity (Kane & Engle; 2003; cf. Long & Prat, 2002; Miyake,
Friedman, Emerson, Witzki, & Howerter; 2000). The ratio of congruent Stroop trials was
When The Going Gets Tough… 11
experimentally manipulated such that there were either 75% congruent trials or 0% congruent trials
(cf. Logan & Zbrodoff, 1979). The underlying idea was that a large proportion of congruent trials
would encourage participants to neglect the task intention to concentrate on the ink color because
reading the word meaning would lead to correct responses for the majority of trials. By contrast, the
absence of congruent trials was thought to discourage people from neglecting the task intention. In
line with this assumption, Stroop interference was greater in the 75% condition compared to the 0%
condition. More important, however, Stroop interference in the 75% condition was greater for low
capacity individuals than for high capacity individuals. These findings suggest that sufficient
working memory capacity is required to maintain an explicit intention in memory during cognitive
control.
Working Memory under High Demands
People may not always be able to fully utilize their working memory capacity in a given
situation (cf. Ashcraft & Kirk, 2001; Schmader & Johns, 2003). Indeed, sustained use of working
memory can make people less able to utilize their working memory capacity. For instance,
deliberate attempts at controlling one’s thoughts leads to performance decrements in subsequent
reasoning and comprehension tasks (e.g., Schmeichel, Vohs, & Baumeister, 2003; cf. Baumeister &
Vohs, 2004; Muraven & Baumeister, 2000). Furthermore, sustained cognitive control leads to
performance impairments in the same task (Lorist, Klein, Nieuwenhuis, De Jong, Mulder, &
Meijman, 2000), or in subsequent tasks that rely on working memory (Van der Linden, Frese, &
Meijman, 2003). To the extent that working memory is involved in thought suppression and
cognitive control, these findings indicate that sustained use of working memory can reduce its
effectiveness. In the present dissertation, I refer to conditions of sustained working memory use as
high demanding. By contrast, conditions that are not characterized by sustained working memory
use I refer to as low demanding.1.4
When The Going Gets Tough… 12
High demands may decrease the effectiveness of working memory in a wide range of
everyday life situations that are characterized by, for instance, the activation of multiple conflicting
goals (Kuhl & Helle, 1986; Shah, Kruglanski, & Friedman, 2003), demanding relationships
(Baldwin, Carrell, & Lopez, 1990), pending assignments (Higgins, 1987), performance pressure
(Beilock, Kulp, Holt, & Carr, 2004), or compelling time constraints (De Dreu, 2003). In all these
situations, working memory remains activated for some time.1.5 In line with this reasoning, high
demands have been found to impair subsequent performance on tasks that require high effectiveness
of working memory but not on tasks that can be performed on an automatic or routine level
(Beilock et al., 2004; Boksem, Lorist, & Meijman, 2005).
A possible reason why high demands can reduce the effectiveness of working memory is
because high demands impair the updating function of working memory. As noted above, the
updating function makes working memory more efficient because it helps to erase irrelevant
information and to maintain relevant information. When the updating function is impaired, working
memory operates inefficiently, which in turn reduces its effectiveness (cf. Eysenck & Calvo, 1992).
Taken together, high demands can impair working memory because they reduce the efficiency of
working memory to update its contents.
Coping with Demands: The Role of Action versus State Orientation
A frequently held position in contemporary social psychology is that people are relatively
passive respondents to external influences rather than active and self-determined agents (however,
see Ryan & Deci, 2004). This view is bolstered by observations that human behavior is greatly
determined by automatic processes and routines (Bargh, 1994; Bargh & Chartrand, 1999), and that
perceptions of control can be illusory (Wegner, 2002). In addition, people’s actual control over their
thoughts and behavior often seems to be suboptimal due to capacity constraints (e.g., Dijksterhuis,
Bos, Nordgren, & Van Baaren, 2006; cf. Pashler, 1994), or may even break down completely due to
working memory’s tendency to lose its effectiveness after sustained use (Schmeichel et al., 2003;
When The Going Gets Tough… 13
Van der Linden et al., 2003). In light of these limitations, one may indeed wonder whether people’s
active agency is restricted to the scarce moments in life that are relatively low demanding.
A rather different view on human agency emerges from action control theories (Gollwitzer,
1993; Kuhl, 1984). A fundamental assumption of action control theories is that people are often
able to mobilize intentional control processes when they encounter hindrances to perform an action
(cf. Ach, 1910; James, 1890). Because high demands can be an important hindrance during goal
pursuit, they may lead people to shield their intentions more intensively. However, high demands
may not invariably promote intensified shielding. According to personality systems interactions
(PSI) theory (Kuhl, 2000, 2001), an elaboration of Kuhl’s (1984) original action control theory,
reactions under high demands depend on whether people are in a meta-static (change-promoting),
or a cata-static (change-preventing) regulatory mode. When in the meta-static mode, people are
decisive and active to pursue intentional action. A meta-static mode is therefore referred to as
action orientation. When in the cata-static mode, however, people are indecisive and hesitant to
change their mental and behavioral states. The cata-static mode is therefore referred to as state
orientation.

A person may respond in an action- or state-oriented manner depending on the situational
context. However, there also exist relatively stable individual differences in action versus state
orientation (Kuhl, 1994a, 2000; Kuhl & Beckmann, 1994a). Based on this idea, Kuhl (1981, 1994b)
When The Going Gets Tough… 16
developed a self-report questionnaire (ACS-90) to assess individual differences in action versus
state orientation.1.6 Each item of the ACS-90 represents a demanding situation and an action- versus
state-oriented way to cope with the situation. The items of the ACS-90 are listed in Table 1.1.
Based on their responses, some individuals can be classified as relatively more action-oriented or
more state-oriented.
Individual differences in action versus state orientation likely originate from early childhood
experiences with demanding situations. Specifically, children who are encouraged by their care-
takers to motivate themselves when they are confronted with obstacles are more likely to develop
an action orientation. By contrast, children whose environments discourage them from motivating
themselves (i.e., overly controlling or neglecting environments), are more likely to develop a state
orientation (cf. Koole, Kuhl, Jostmann, & Finkenauer, 2006; Kuhl, 2000).
Theoretically, action versus state orientation may be an important moderator of how people
respond to high demands. Specifically, high demands may trigger action-oriented individuals to
utilize their psychological resources more efficiently in order to better exert action control. By
contrast, high demands may not have similar effects among state-oriented individuals. Specifically,
state-oriented individuals may fail to utilize their psychological resources more efficiently and,
consequently, may not be able to better exert action control under high demands. The effects of
high demands on action control among action- versus state-oriented individuals are likely reflected
on various dimensions of action control including cognition, affect, and behavioral outcome. Based
on these assumptions, the central hypothesis of the present dissertation is that action- compared to
state-oriented individuals are better able to cope efficiently with the cognitive, affective, and
behavioral consequences of high demands.
Research on Action versus State Orientation
Over the past 25 years, individual differences in action versus state orientation have been
extensively investigated by a number of different researchers in various countries including
When The Going Gets Tough… 17
Germany, The Netherlands, and the USA. Throughout this research, action versus state orientation
has been found to influence people’s functioning across a broad range of different domains
including health (Bossong, 1998), work (Diefendorff, Hall, Lord, & Strean, 2000), sports
(Heckhausen & Strang, 1988), and education (Diefendorff, Lord, Hepburn, Quickle, Hall, &
Sanders, 1998). Moreover, the effects of action versus state orientation have been found to be
independent from other well-established psychological constructs such as the Big Five personality
dimensions and self-efficacy. An overview of the latter research is provided in Tables 1.2 – 1.3 (for
reviews, see Diefendorff et al., 2000; Koole & Kuhl, in press; Kuhl & Beckmann, 1994a).

To date, research has uncovered some initial support for the general idea that action-oriented
individuals cope more efficiently with high demands than state-oriented individuals. A first line of
research suggests that action- compared to state-oriented individuals are more skilled at cognitive
shielding as reflected by efficient use of cognitive resources under high demands. In particular,
action-oriented individuals report less intrusive thoughts (Kuhl & Fuhrmann, 1998) and fewer
When The Going Gets Tough… 18
everyday lapses of attention (Kuhl & Goschke, 1994b) than state-oriented individuals. Action-
oriented individuals have also been found to use more efficient and parsimonious decision-making
strategies under time pressure than state-oriented individuals (Stiensmeier-Pelster, John, Stulik, &
Schürmann, 1989).
A second line of research suggests that action-oriented individuals are more skilled at
affective shielding as reflected by the ability to maintain or restore a positive affective state under
high demands. One indicator of such affective shielding is that, under high demands, action-
oriented individuals maintain better access to their emotional preferences (Baumann & Kuhl, 2005)
and a more positive and autonomous self-image (Koole, 2004) compared to state-oriented
individuals. Moreover, action- compared to state-oriented individuals report higher well-being
(Baumann, Kaschel, & Kuhl, 2005) and less depression (Bossong, 1998) during stressful periods of
their personal lives. Among college students, having an action orientation is correlated with
increments in positive affect and energy over the course of a semester (Brunstein, 2001).
Recently, Koole and Jostmann (2004) proposed that affective shielding among action-
oriented individuals takes place on an intuitive level that may not rely on conscious control. In line
with this proposition, action- compared to state-oriented individuals under high demands were
faster to provide positive responses to negative target words in a task that measured intuitive
affective shielding (i.e., an affective Simon task; De Houwer & Eelen, 1998). Moreover, action-
compared to state-oriented individuals under high demands were faster to detect happy faces in
crowds of angry faces in a face-discrimination task (Öhman, Lundqvist, & Esteves, 2001).
Importantly, action-oriented individuals were not faster to give negative responses to positive
words, or to detect angry faces in crowds of happy faces, respectively. Accordingly, high demands
led action-oriented individuals to shield specifically against negative affect rather than simply
increasing overall task speed.

Finally, a third line of research has found that action- compared to state-oriented individuals
are better able at behavioral shielding as reflected by the ability to act upon their intentions under
high demands. For instance, various field studies have found action-oriented individuals are more
successful than state-oriented individuals in maintaining a healthy diet (Palfai, 2002; cf. Fuhrmann
& Kuhl, 1998), avoiding negative behavior related to alcohol abuse (Palfai, McNally, & Roy,
2002), and enacting health- and study-related intentions (Beswick & Mann, 1994; Bossong, 1998;
Kendzierski, 1990). Furthermore, experimental research indicates that action- compared to state-
oriented individuals have fewer difficulties to initiate new courses of action (Kuhl & Beckmann,
1994b; Dibbelt, 1996). The reported deficits among state-oriented individuals may explain why
state-oriented individuals receive more negative supervisor ratings (Diefendorff et al., 2000; cf.
Diefendorff, Richard, & Gosserand, 2006), and display reduced academic success at college
(Bossong, 1998; Diefendorff et al., 1998), and impaired athletic performance when pressure to
perform well is high (Heckhausen & Strang, 1988).
Taken together, previous research supports the idea that action orientation contributes to
cognitive, affective, and behavioral shielding against high demands. However, several important
questions remain. First, previous research has not systematically measured or manipulated the level
of demand. It is therefore unclear whether the reported effects are due to higher coping efficiency
or, alternatively, to generally higher levels of cognitive capacity and positive affect among action-
oriented individuals. From the present theoretical perspective, however, action-oriented individuals
should only function more efficiently than state-oriented individuals under high demands. Indeed,
under low demands, state-oriented individuals are expected to function as well or even better than
action-oriented individuals (cf. Koole, Kuhl, Jostmann, & Vohs, 2005). Second, previous research
has largely relied on field studies that lack the control provided by strictly experimental settings. As
a result, much remains unknown about the precise mechanisms through which action orientation
facilitates coping with high demands. Third and last, previous research has often failed to use
When The Going Gets Tough… 20
validated measures of cognitive, affective, and behavioral performance. Consequently, the
interpretation of many reported findings remains ambiguous.
The Present Dissertation
The research reported in the present dissertation provides a systematic and methodologically
rigorous examination of the role of action versus state orientation in coping with high demands.
Throughout the present dissertation, my central hypothesis was that action-oriented individuals
cope more effectively with high demands than state-oriented individuals. I investigated this
hypothesis using various operationalizations of demands, and across cognitive, affective, and
behavioral measures. More specifically, I examined the impact of action versus state orientation
varying demands on working memory capacity in Chapter 2. In Chapter 3, I examined the role of
action versus state orientation in regulating aversive affective responses, a skill that is relevant to
coping with demanding situations, which often involve worsened affect (Koole & Jostmann, 2004).
In Chapter 4, I examined the impact of action versus state orientation varying demands on
behavioral efficiency, i.e., on Stroop interference.
Level of demand was experimentally manipulated in various ways including visualization
procedures (Chapter 2; cf. Baldwin & Sinclair, 1996), the visual presentation of angry faces outside
of participants’ conscious awareness (Chapter 3; cf. Chartrand & Bargh, 1996), sustained
performance on difficult tasks (Chapter 4; cf. Lorist et al., 2000), or the activation of intention
memory (Chapter 4; cf. Kuhl & Helle, 1986). I also measured level of demand in participants’
personal lives in one study (Chapter 4; cf. Baumann et al., 2005).
Chapter 2 examined the utilization of working memory capacity as a function of different
levels of demand and action versus state orientation. Working memory is a key memory system that
is involved in cognitive control (Kane & Engle, 2003). In order to exert cognitive control under
high demands it is therefore important that people can utilize their working memory efficiently even
in demanding situations. Working memory was assessed by means of an OSPAN task (Turner &
When The Going Gets Tough… 21
Engle, 1989), and an intention memory task (Goschke & Kuhl, 1993). The central hypothesis in
Chapter 2 was that action-oriented individuals utilize their working memory more efficiently under
high demands, whereas state-oriented individuals utilize their working memory more efficiently
under low demands as indicated by respectively higher span scores and greater intention memory.
People’s basic affective reactions can trigger corresponding behavioral responses (Gray,
2001; Neumann et al., 2003). Because such responses may be incompatible with people’s
intentions, it is important that people are able to shield against undesired affective reactions.
Previous research has shown that action- compared to state-oriented individuals are better skilled at
affective shielding, especially under high demands (Koole & Jostmann, 2004). Building on this
research, Chapter 3 examined whether action- compared to state-oriented individuals are also more
effective at affective shielding when affective responses are triggered subliminally, i.e., outside of
conscious awareness. Subsequent to a subliminal affect induction (Chartrand et al., 2006),
participants indicated their current affective states on an implicit affect measure (Tesser, Millar, &
Moore, 1988). The hypothesis was that action- compared to state-oriented individuals displayed a
more positive affective state after subliminal priming with negative affect.
The ability to override inappropriate action tendencies is vital for intentional action. It is
therefore important that people are able to exert cognitive control even under high demands.
Chapter 4 examined the role of varying levels of demand and action versus state orientation on
cognitive control using Stroop tasks. The central hypothesis in Chapter 4 was that high demands
lead to greater cognitive control among action- compared to state-oriented individuals. Furthermore,
following Kane and Engle (2003), the number of congruent Stroop trials was manipulated in order
to examine the role of working memory in cognitive control. The hypothesis was that action-
compared to state-oriented individuals display greater cognitive control when the number of
congruent Stroop trials is high, i.e., when cognitive control is especially dependent on working
memory.

The reader may observe some redundancies throughout the chapters in terms of theoretical
background and methodology. These redundancies are deliberate because they allow each chapter
to be read and understood separately without the necessity to skip back and forth between different
chapters. In fact, each empirical chapter is based on a published or submitted scientific article. At
the same time, however, it remains important to integrate the various findings and to consider them
in a broader perspective. An initial step towards such theoretical integration is provided in Chapter
5. Specifically, Chapter 5 suggests that more effective coping with high demands among action-
oriented individuals on cognitive, affective, and behavioral levels is due to their greater efficiency
to update working memory. This idea is discussed in relation to contemporary models of working
memory regulation (Braver & Cohen, 2000; Kuhl, 2000).

Cognitive Shielding
Action Orientation Moderates the Impact of
Demanding Relationship Primes on Working Memory Capacity2.1
The ability to remember the right things at the right time is often critical for achieving one's
goals. For instance, remembering the departure time of one’s train, the name of the restaurant where
one is supposed to meet a business associate, or that one should buy a birthday present for one’s
partner all help to avoid decidedly unpleasant experiences. Unfortunately, various circumstances
such as unexpected phone calls, heavy workloads, or pressing social commitments often make it
necessary to consider many things simultaneously (Shah, Kruglanski, & Friedman, 2003) leaving
train schedules, restaurant names, and birthday presents candidates for unwitting neglect (Reason,
& Mycielska, 1982). To prevent long delays, lost business, disappointed partners, and other
misfortunes, people need to rely on their working memory capacity (Engle, Kane, & Tuholski,
1999).
Working memory capacity is an immensely useful psychological resource that allows people
to remember important information even when they are temporarily distracted. Past research and
theorizing make inconsistent predictions regarding the effects of situational demands on working
memory capacity. One the one hand, people may utilize their working memory capacity less
efficiently under high demands (e.g., Baumeister, 1984). On the other hand, high demands may lead
people to mobilize greater control resources and thereby utilizing their working memory capacity
more efficiently (e.g., Botvinick, Braver, Barch, Carter, & Cohen, 2001). In the present research,
we suggest a possible way to reconcile these conflicting notions. Based on personality systems
interactions (PSI) theory (Kuhl, 2000, 2001), we propose that the effects of situational demands on
working memory capacity are moderated by action versus state orientation. Action-oriented
individuals utilize their working memory capacity more efficiently in high demanding situations,
When The Going Gets Tough… 24
whereas state-oriented individuals utilize their working memory capacity less efficiently in high
demanding situations. In the following paragraphs, we begin by reviewing the literatures on
working memory capacity and action versus state orientation. We then present two experiments that
tested our theoretical analysis.
How Working Memory Works
Working memory protects stored information against premature loss due to strong
distracters (Baddeley, 1986; Engle et al., 1999; cf. Miyake & Shah, 1999). This vital task involves
both short-term storage and attentional processes. Stored information in working memory is
unlikely to be consciously represented at all times. Instead, such information persists in a state of
heightened activation that makes it explicitly available to conscious awareness. Due to capacity
constraints, working memory can only process a limited amount of explicit information
simultaneously.
Working memory capacity is especially important when people have to remember what to
do. Oftentimes, people have to postpone their intentions because they cannot enact them
immediately (Kvavilashvili, 1987). To the extent that the intended action is novel, difficult, or can
be easily forgotten, the intention needs to remain represented in an explicit format until the situation
is appropriate for enactment. Given that working memory supports such explicit formats (Baddeley,
1986), working memory is intimately involved in the maintenance of explicit intentions in memory
(Kane & Engle, 2003). The latter function is known as intention memory (Kuhl, 2000). There are
some subtle differences between intention memory and working memory (for a discussion, see
Kazén & Kuhl, 2005; Kuhl, & Kazén, 1999). Nevertheless, intention memory and working memory
both rely on the same limited mental resources and are supported by partly overlapping brain
structures (e.g., left prefrontal cortex; cf. Fuster, 1995). In recognition of the important functional
parallels between the two memory systems, we emphasize the similarities between working
memory and intention memory in the present context.
When The Going Gets Tough… 25
One of the most popular measures of working memory capacity is the Operation Span
(OSPAN) task (Turner & Engle, 1989). In the OSPAN task, participants are required to calculate
simple arithmetic equations while retaining short series of words in memory for later recall.
Working memory capacity is reflected by a person’s span, i.e. the number of words that can be
recalled correctly while performing the calculations. Using various kinds of span tasks, research has
shown that there exist substantial individual differences in working memory capacity. Relative to
individuals with small memory spans, individuals with large memory spans display greater
resistance to distraction, higher general fluid intelligence, and better academic achievement (for a
review, see Feldman Barrett, Tugade, & Engle, 2004).
The Dual Role of Demand
Depending on situational factors, people may not always be able to utilize their working
memory capacity efficiently (cf. Eysenck & Calvo, 1992). Based on previous research and
theorizing (Braver & Cohen, 2000; Kuhl, 2000; Van der Linden, Frese, & Meijman, 2001), we
suggest that people may utilize their working memory capacity less efficiently under conditions of
sustained working memory load. Sustained working memory load may impair the updating function
of working memory such that situation-irrelevant information cannot be erased and new tasks
cannot be properly processed. In the present context, we refer to conditions of sustained working
memory load as high demanding. By contrast, we term conditions without such load low
demanding.
High demands may leave less working memory capacity available in a variety of everyday
life situations or experimental settings such as during the activation of difficult intentions (Kuhl &
Helle, 1986), or multiple incompatible goals (Shah et al., 2003), in the presence of demanding
relationships (Baldwin, Carrell, & Lopez, 1990), or after prolonged engagement in tasks that require
continuous working memory activation (Lorist, Boksem, & Ridderinkhof, 2005). In line with this
idea, previous research has found that people utilize their working memory capacity less efficiently
When The Going Gets Tough… 26
as a result of stressful life events (Klein & Boals, 2001), mental fatigue (Van der Linden et al.,
2003), ego depletion (Schmeichel, Vohs, & Baumeister, 2003), or when people try to overcome
strong impulses (Zwaan & Truitt, 1998). Evidence thus suggests that working memory is prone to
“choking under pressure” (Baumeister, 1984).
The notion that people better utilize their working memory capacity under low rather than
high demands is intuitively plausible. However, high demands may not always have a negative
impact on working memory capacity. When people encounter high demanding conditions, this may
signal to people that their current amount of working memory capacity is not sufficient. In response,
people may channel more resources to their working memory, thereby utilizing their working
memory capacity more efficiently under high demands. This idea is consistent with recent notions
of top-down control processes. Contemporary theories of action control (Gollwitzer, 1996; Kuhl,
1984; Moskowitz, Li, & Kirk, 2004) assume that people more intensively shield their intentions
against unwitting loss when they experience or anticipate difficulties to enact their intentions.
Furthermore, neuropsychological research indicates that the detection of conflict in information
processing can lead to compensatory strengthening of cognitive control in Stroop-like interference
tasks (Botvinick et al., 2001). Thus, to the extent that working memory capacity is implicated in
action control and cognitive control, people may better utilize their working memory capacity under
high demands.
Regulation of Working Memory: The Case of Action versus State Orientation
It appears that high demands can either undermine or facilitate working memory. As such,
there likely exist moderating variables that determine the direction of the impact of situational
demands on working memory capacity. One such moderator may be the person’s disposition
towards action versus state orientation (Kuhl, 1984, 1994a, 2000; Kuhl & Beckmann, 1994a).
Action orientation is conceived as a meta-static (change promoting) regulatory mode that is
characterized by decisiveness and initiative. Action orientation thus facilitates intentional action. By
When The Going Gets Tough… 27
contrast, state orientation is conceived as a cata-static (change preventing) regulatory mode that is
characterized by indecisiveness and hesitation. State orientation thus leads to the perseverance of
current behavioral and mental states. In other words, action versus state orientation reflects the
person’s ability to induce the behavioral and mental changes to terminate the status quo (Kuhl,
1984). According to PSI theory (Kuhl, 1994a, 2000), action versus state orientation varies
chronically between individuals, such that some individuals are more action-oriented, whereas
others are more state-oriented.
Action versus state orientation is distinct from classic motivational constructs (Kuhl, 1984).
More specifically, classic motivational constructs refer to people’s preferences to select a particular
class of motivational tendencies. For instance, people may choose to pursue mastery goals or
performance goals (Elliot & McGregor, 2001), adopt a promotion focus or a prevention focus
(Higgins, 1998), or be driven by implicit or explicit needs (McClelland, Koestner, & Weinberger,
1989). By contrast, action versus state orientation refers to the efficiency with which people can
instigate the behavioral and mental changes necessary to enact a particular motivational tendency.
Consequently, action orientation can increase the enactment of any motivational tendencies that
involve making difficult behavioral and mental changes. Consistent with this reasoning, action-
compared to state-oriented individuals are more efficient on both mastery and performance goals
(Diefendorff, 2004), report having more success in both promotion and prevention goals (Koole,
2005)2.2, and are more successful at reconciling their implicit and explicit needs (Baumann,
Kaschel, & Kuhl, 2005). In short, both theoretical and empirical considerations indicate that the
impact of action versus state orientation occurs over and above classic motivation constructs.
When The Going Gets Tough… 28
Particularly relevant in the present context, action- versus state-oriented individuals have
been found to respond very differently to situational demands. When confronted with increased
demands, action-oriented individuals tend to mobilize their self-regulatory resources. For instance,
relative to their state-oriented counterparts, action-oriented college students are better able to
organize the multiple demands of college life (Diefendorff, Lord, Hepburn, Quickle, Hall, &
Sanders, 1998). In addition, action-oriented individuals better regulate their affective states under
high demands (Koole & Jostmann, 2004; cf. Jostmann, Koole, Van der Wulp, & Fockenberg, 2005;
Chapter 3). Finally, action-oriented individuals maintain or even increase their task performance
under demanding conditions (Heckhausen & Strang, 1988). By contrast, state-oriented individuals
tend to choke under increasing demands (Heckhausen & Strang, 1988). Notably, state-oriented
individuals do not necessarily display performance deficits under low demanding conditions.
Indeed, state-oriented individuals may outperform action-oriented individuals under supportive
conditions, presumably because state-oriented individuals are more receptive to external
motivational support (Koole, Kuhl, Jostmann, & Vohs, 2005).
Given that action versus state orientation generally moderates how people are coping with
demands, it stands to reason that action versus state orientation may also moderate the impact of
demands on working memory capacity. Specifically, the indecisiveness and hesitation that are
characteristic of state-oriented individuals may translate into a tendency to maintain stored
information in working memory even when quick decisions and initiative are more desirable
(Stiensmeier-Pelster, 1994). State-oriented individuals indeed have been found to display a general
tendency to engage their working memory capacity (cf. Goschke & Kuhl, 1993). Whenever an
additional working memory load is externally induced under high demands (e.g., through stressful
life events), state-oriented individuals are likely to remain under such load thereby decreasing the
working memory capacity that is available for subsequent tasks (Jostmann & Koole, 2006; Chapter
When The Going Gets Tough… 29
4). Consequently, state-oriented individuals may utilize their working memory capacity less
efficiently under high demands.
By contrast, action-oriented individuals are likely to use their working memory capacity
more efficiently with increasing demands. This mobilization pattern is likely due to the decisiveness
and initiative that characterize action-oriented individuals (Kuhl, 1984), which should help these
individuals to reduce the duration and severity of working memory load. Accordingly, when
working memory load is induced under high demands, action-oriented individuals are likely to
terminate this load as soon as task requirements permit. High demands may thus activate action-
oriented individuals’ tendency to update their working memory, thereby making more working
memory capacity available for subsequent tasks (Jostmann & Koole, 2006; Chapter 4; Stiensmeier-
Pelster, 1994). By regularly updating the contents of their working memory, action-oriented
individuals are likely to better utilize their working memory capacity under high demands.
It is important to note that the preceding functional differences between action- and state-
oriented individuals only apply to high demanding conditions. Low demanding conditions put less
strain on working memory, so that the functional advantage of action-oriented individuals will
diminish with lower levels of demand. In fact, some low demanding contexts may even provide
state-oriented individuals with a functional advantage. Such benefits of state orientation are
especially likely to occur when the situational context is rewarding. The experience or anticipation
of rewards is conducive to the updating of information in working memory (cf. Braver & Cohen,
2000; Dreisbach & Goschke, 2004). State-oriented individuals are more receptive than action-
oriented individuals to externally provided incentives (cf. Koole et al., 2005). A rewarding context
may therefore allow especially state-oriented individuals to free up their working memory capacity.
The Present Research and Hypotheses
The present research sought to provide the first systematic empirical test of the idea that
action versus state orientation moderates the impact of situational demands on working memory
When The Going Gets Tough… 30
capacity. To induce high or low levels of situational demands, we primed a demanding or accepting
relationship schema (Baldwin & Sinclair, 1996; Koole & Jostmann, 2004). Previous research found
that priming mental representations of relationships with a significant other activates a host of
goals, expectations, and self-evaluations that characterize the interaction with that person (Baldwin
et al., 1990; Fitzsimons & Bargh, 2003; Shah, 2003; cf. Chen, Boucher, & Tapias, 2006). Building
on these findings, we reasoned that the activation of relationship schemas would also have
consequences for working memory capacity. Specifically, priming one’s relationship with a
demanding other likely puts a high strain on working memory thereby exhausting its capacity. By
contrast, priming the relationship with an accepting other likely puts a low strain on working
memory. Indeed, to the extent that accepting others provide a rewarding psychological context in
which one feels accepted unconditionally, priming an accepting relationship may even help
individuals to free up working memory capacity (cf. Koole et al., 2005; Koole, Kuhl, Jostmann, &
Finkenauer, 2006). In sum, visualizing a demanding person may induce a psychological context of
high demand, whereas visualizing an accepting person may induce a psychological context of low
demand.
Following the demand manipulation, we administered a set of validated measures of
working memory capacity. In Study 2.1, we measured working memory capacity by means of an
OSPAN task (Turner & Engle, 1989). In Study 2.2, we measured working memory capacity by
means of an intention memory task (Goschke & Kuhl, 1993). Given that working memory capacity
is functionally linked with intention memory (Kazén & Kuhl, 2005), we expected parallel effects on
the intention memory task and the OSPAN task. Specifically, we predicted that action-oriented
individuals would better utilize their working memory capacity under high demands such that
visualizing a demanding relationship leads to higher span scores (Study 2.1), and better intention
memory (Study 2.2) than visualizing an accepting relationship. By contrast, we predicted that state-
oriented individuals’ working memory would choke under high demands such that visualizing a
When The Going Gets Tough… 31
demanding relationship leads to lower span scores and worse intention memory than visualizing an
accepting relationship.
Study 2.1
Method
Participants and Design
Seventy-four paid volunteers at the Vrije Universiteit Amsterdam (28 men and 46 women,
average age 20) participated in the experiment. The experimental design was 2 (orientation: action
vs. state) x 2 (visualization: demanding vs. accepting) between participants. Participants were
randomly assigned to the demanding (N = 35) or the accepting (N = 39) condition. The main
dependent variable consisted of the number of correctly remembered words during the OSPAN
task.
Procedure
Upon arrival in the laboratory, participants were led into individual cubicles, each
containing a computer. Experimental instructions were administered via a computer-program.
Participants were first informed that they would participate in several unrelated studies that were
allegedly administered together for efficiency reasons. Participants then moved on with the first
study, which was introduced as a study on personality and contained our assessment of individual
differences in action versus state orientation. Next, participants continued with a visualization task
during which either high or low levels of demand were induced. Subsequently, participants
performed the OSPAN task. After this, participants answered a manipulation check and provided
some biographical information. Finally, participants were debriefed, thanked, and paid by the
experimenter.
Independent variables
Individual Differences. To assess individual differences in action versus state orientation, we
used a Dutch translation of the Action Control Scale (ACS-90; Kuhl, 1994b). In both studies, we
When The Going Gets Tough… 32
administered the demand-related (AOD) and the threat-related (AOT) subscale of the ACS-90.
According to PSI theory (Kuhl, 2001, p. 243; cf. Baumann et al., 2005; Koole & Jostmann, 2004),
demand and threat represent different aversive states each related to different trigger conditions and
different symptoms. AOD measures whether a person is decisive and active (action-oriented) or
indecisive and inertial (state-oriented) under high demands. By contrast, AOT measures whether a
person becomes challenged (action-oriented) or remains threatened (state-oriented) in situations that
are perceived as danger to one’s well-being or self-image (cf. Blascovich & Mendes, 2000). We
found no effects of AOT in the present investigation, which indicates that our manipulation did not
trigger challenge and threat processes, all Fs < 1. We therefore report only effects of AOD. For the
sake of convenience, we use the more general term “action versus state orientation” throughout this
chapter to refer to AOD unless a more precise distinction is required.
The AOD subscale consists of twelve items, which were intermingled and presented in a
different random order for each participant. Each item describes a demanding situation and an
action-oriented versus state-oriented way of coping with that situation. For each item, participants
are asked to select the response that best described their own reaction in that situation. An example
item is “When I have a lot of important things to do and they must all be done soon: (a) I often
don’t know where to begin, or (b) I find it easy to make a plan and stick with it”. In this example,
option a reflects the state-oriented response and option b reflects the action-oriented response.
Action-oriented responses were coded as 1 and state-oriented responses were coded as 0 and
summed for the entire subscale. Reliability for the AOD scale was sufficient (Kuder-Richardson
(KR) 20 coefficient = .78). Scores could range from 0-12. Participants who gave seven or more
action-oriented responses were assigned to the action-oriented group (N = 42); participants who
gave six or fewer action-oriented responses, were assigned to the state-oriented group (N = 37).2.3
Visualization Manipulation. The visualization procedure was modeled after Baldwin and
Sinclair (1996). During the procedure, which was introduced as a “visualization exercise”,
When The Going Gets Tough… 33
participants were asked to visualize a particular person from their own life. In the demanding
condition, participants were requested to think of a person who was highly demanding of them.
Participants had to type in the initials of this person, which were used throughout the exercise in
referring to the visualization target. Participants were instructed to vividly imagine being with this
person and to re-experience their thoughts and feelings associated with this person. At various
stages during the visualization, participants typed in the experiences that were evoked by the
visualization. At the end of the exercise, participants were asked to rate their ease of visualization.
In the accepting visualization condition, participants went through the same procedure, but instead
visualized a person who was highly accepting of them.
Dependent Measure
Working Memory Task. To measure working memory capacity we used a computerized
version of the OSPAN task adapted from Schmader and Johns (2003; cf. Turner & Engle, 1989).
The OSPAN task interleaves short series of words to memorize with simple mathematical equations
to be evaluated. In the present investigation, each equation began with the multiplication or division
of two positive integers [e.g., 5 x 7]. The product of this operation then had to be added to, or
subtracted from, another positive integer. For each equation, the answer was included in the
expression. The task of the participants was to evaluate by means of a key-press whether the
equation was correct or incorrect [e.g., Is (5 x 7) – 12 = 23?]. When the equation was correct
participants had to press the A-button on the left side of the keyboard, whereas they had to press the
6-button on the numeric pad on the right side of the keyboard when the equation was incorrect.
After each equation, a word to memorize was presented. After a series of equation word pairs (i.e.,
a set) participants were requested to type in all words they recalled from the preceding set. After
this, a new set of equation word pairs started.
Sets differed in length varying from three to five equation word pairs per set. Six sets of
each length were presented, allowing scores to range from 0 to 72. Presentation order of the sets
When The Going Gets Tough… 34
was randomized for each participant, such that the number of words to recall was unknown until
recall. The generation of mathematical equations followed the criteria of Schmader and Johns
(2003). Half of the equations were correct, the remaining equations were incorrect. The 72 words
used in the test were monosyllabic Dutch nouns that were randomly assigned to sets. Within sets,
equation word pairs were presented in a different random order for each participant. The assignment
of equations and words to sets was identical for all participants.
Each trial within a set began with the appearance of a fixation asterisk on the screen for 1 s
followed by an equation, which remained visible until participants had pressed a response key.
After this, the screen remained blank for 500 ms, followed by the appearance of a word to be
recalled. After 2 s, the screen went blank again for 1 s, followed by the next trial. Sets were
separated by the announcement “next set”, which remained visible for 3 s. The computer
unobtrusively recorded the words recalled, participants’ responses on the equations, and the time
spent on each equation.

Results
Manipulation Check. At the end of the experimental session, participants were asked to rate
on two items how demanding and how accepting the person was whom they had visualized (1 = not
When The Going Gets Tough… 35
at all, 9 = very much). These items were scored in the same direction and averaged (Cronbach’s
alpha = .88). The visualized person was rated as more demanding in the demanding condition than
in the accepting condition, F(1, 70) = 74.08, p < .001, η p2 = .51 (M = 5.61 vs. M = 2.68). No effects
of action versus state orientation were found on this index, all Fs < 1.
OSPAN Performance. Span scores were assessed by counting the total number of correctly
recalled words. (Redoing the analyses with the number of correctly recalled words only from sets
where all the words in the set were recalled correctly yielded equivalent results; cf. Schmader &
Johns, 2003.) We subjected average span scores to a 2 (orientation: action vs. state) x 2
(visualization: demanding vs. accepting) ANOVA, which yielded a significant interaction, F(1, 70)
= 11.17, p < .002, η p2 = .14. Relevant means are displayed in Table 2.1. Simple effects analyses
revealed that action-oriented participants displayed marginally higher span scores in the demanding
condition than in the accepting condition, F(1, 70) = 5.89, p < .06, η p2 = .08 (M = 69.00 vs. M =
66.21). By contrast, state-oriented participants had significantly lower span scores in the demanding
condition than in the accepting condition, F(1, 70) = 5.31, p < .03, η p2 = .07 (M = 66.05 vs. M =
68.80). Another way to interpret the data is to note that, in the demanding condition, action-oriented
participants had higher span scores than state-oriented participants, F(1, 70) = 6.11, p < .02, η p2 =
.08 (M = 69.00 vs. M = 66.05). In the accepting condition, however, the pattern was reversed, such
that action-oriented participants had lower span scores than state-oriented participants, F(1, 70) =
5.07, p < .03, η p2 = .07 (M = 66.21 vs. M = 68.80).
Supplementary Analyses. Additional analyses revealed that the results remained identical
when we controlled for the number of correctly evaluated equations (Grand M = 88%). Moreover,
we found no effects of orientation or visualization on the number of correctly evaluated equations;
all Fs < 1.

Discussion
As predicted, the effects of situational demands on working memory capacity were
moderated by action versus state orientation. Among action-oriented participants, priming a
demanding relationship context made them utilize their working memory capacity more efficiently
than priming an accepting relationship context as indicated by participants’ OSPAN scores. Action-
oriented individuals thus utilized their working memory capacity especially under demanding
conditions. By contrast, state-oriented participants displayed higher span scores after priming an
accepting compared to a demanding relationship. State-oriented individuals thus utilized their
working memory capacity especially under low demanding conditions. Stated differently, priming a
demanding relationship led to better utilization of working memory capacity among action-
compared to state-oriented participants, whereas the reverse was true after priming an accepting
relationship.
Study 2.2
Study 2.2 examined the effects of situational demands and action versus state orientation on
intention memory. As discussed before, working memory capacity is required for the preparation of
intentional action. Accordingly, a person’s working memory capacity may be reflected in her or his
ability to maintain explicit representations of intentions (Kane & Engle, 2003).
The intention memory task in Study 2.2 differed in several meaningful ways from the
OSPAN task in Study 2.1. The OSPAN task represents a dual-task situation, in which participants
have to memorize information while they are simultaneously processing unrelated information.
Neither type of information is relevant for the preparation of action. By contrast, the intention
memory task did not involve dual-task conditions, and the information processed in the task was
relevant for action preparation. Consequently, extending our empirical analysis to intention memory
provided additional insights into how people utilize their working memory capacity for the purpose
of future action.
When The Going Gets Tough… 37
To assess intention memory, we used the postponed intention task (Goschke and Kuhl,
1993). In this task, participants have to learn a pair of short scripts describing activities (e.g., “clear
a desk”) that entail several intermediate steps (e.g., “sharpen the pencils”). After participants have
learned both scripts, they are informed that they have to execute one of the scripts later (prospective
script). The other script (neutral script) does not have to be executed by the participants. During a
subsequent recognition task, participants then have to decide whether words presented on the
computer screen had appeared in one of the two scripts. Using this paradigm, past research has
found evidence for an intention superiority effect, i.e. faster recognition latencies for words from the
prospective script compared to words from the neutral script (Goschke & Kuhl, 1993).
Based on the theoretical link between working memory capacity and intention memory (cf.
Kazén & Kuhl, 2005), we predicted that action versus state orientation would moderate the impact
of demands on intention memory performance in Study 2.2 much like it did on OSPAN
performance in Study 2.1. Specifically, we predicted that action-oriented participants would display
a greater intention superiority effect under high demanding conditions than under low demanding
conditions. By contrast, we predicted that state-oriented participants would display a greater
intention superiority effect under low demanding than under high demanding conditions.
Method
Participants and Design
One hundred and twenty-six paid volunteers at the Vrije Universiteit Amsterdam (44 men
and 82 women, average age 21) participated in the experiment. The experimental design was 2
(orientation: action vs. state; between participants) x 2 (visualization: demanding vs. accepting;
between participants). Participants were randomly assigned to the demanding (N = 62) or the
accepting (N = 64) visualization conditions. The main dependent variable consisted of participants’
mean recognition times and number of correctly remembered words from the prospective and the
neutral script. Seven participants (5.5% of the entire sample) failed to recognize any words from the
When The Going Gets Tough… 38
neutral script. Because all participants recognized at least some words of the prospective script,
these seven participants had probably misunderstood the task instructions that they should respond
to words of both scripts. Because it was not possible to measure intention superiority effects in
recognition times for these participants, they were removed from the dataset. One additional
participant (.8% of the entire sample) was excluded because he incorrectly indicated that the neutral
script had to be executed.
Procedure
The equipment and general procedure were similar to Study 2.1. Participants first answered
a few questionnaires including the AOD subscale of the ACS-90 (Kuhl, 1994b) to assess individual
differences in action orientation (KR 20 = .73). Based on their responses, sixty-nine participants
were assigned to the state-oriented group, whereas fifty-seven participants were assigned to the
action-oriented group. Next, participants continued with a practice trial of the postponed intention
task. The scripts used in the practice postponed intention task were different from those used during
the actual postponed intention task. After the practice trial, participants performed the visualization
task. Subsequently, participants went on with the actual postponed intention task during which
responses where recorded for analysis. Next, participants performed some unrelated tasks followed
by a manipulation check. Finally, participants were debriefed, thanked, and paid for their
participation.
Dependent Measure
Postponed Intention Task. The postponed intention task was adapted from Goschke and
Kuhl (1993) and consisted of a learning phase, a distracter task, the presentation of the execution
instruction, and a recognition test. The postponed intention task was described to the participants as
a study on people’s memory for simple activities. Participants were informed that they would
receive descriptions of two simple activities on the computer screen. Participants expected that they
had to learn these descriptions, which were referred to as “scripts”, and that their memory for both
When The Going Gets Tough… 39
scripts would be tested in a recognition test. Furthermore, it was stressed that participants would
have to execute one of the two scripts later during the experiment. Which of the two scripts would
be executed was randomly determined by the computer.
The scripts consisted each of a script header (e.g., “setting a table”) and four propositions
describing component activities (e.g., “distribute the plates”). The learning phase started with the
script header of the first script appearing on the screen followed by separate presentations of each of
the four component activities. The header and the components of the script were each displayed for
6 seconds. Subsequently, the entire script was displayed for another 30 seconds. After this, the
second script was presented in an identical way. Subsequently, the entire procedure was repeated
such that both scripts were presented two times to the participants. Next, participants proceeded
with a short distracter task during which they had to count backwards in steps of three from a three-
digit number for 45 seconds. Subsequently, participants received the instruction which of the two
scripts they had to execute. The instruction consisted of the word “execute” followed by one of the
script headers (the prospective script). In a second row, the words “do not execute” were displayed
followed by the second script header (the neutral script). This execution instruction was displayed
for 6 seconds. Assignment of the two scripts was counterbalanced between participants such that
each script served equally often as the prospective script and the neutral script respectively.
Immediately after the presentation of the execution instruction, participants received a
recognition test, during which single words were presented on the screen. Participants were required
to indicate for each word whether they had seen that word in one of the two scripts. If the word was
identified as a word from one of the two scripts, participants were to press the A-key on the left side
of the keyboard. When the word was identified as a new word, participants were to press the 6-key
on the numeric pad on the right side of the keyboard. Participants were further told to respond
quickly and accurately and to guess whenever they were not sure about the correct response.
The recognition test started with four warming-up trials. After this, 44 words were presented
When The Going Gets Tough… 40
sequentially to the participants. Half of the words were derived from one of the two scripts; the
remaining words were new. Half of the new words were semantically related to respectively one of
the scripts. The remaining new words were semantically unrelated to either script. Each word
remained on the screen until participants had given a response. The screen then remained blank for
1.5 seconds. The computer unobtrusively recorded participants’ responses and response latencies.
After the recognition test, participants had to indicate which script had to be executed. Actual
execution of the prospective script was only required during the practice postponed intention task.

Results
Manipulation Checks. At the end of the experimental session, participants were asked to rate
how demanding and how accepting the person was whom they had visualized (1 = not at all, 9 =
very much). These two items were scored such that higher scores indicated higher perceived
demandingness of the visualized person (Cronbach’s alpha = .54). Given the low reliability
coefficient, we conducted a 2 (orientation) x 2 (visualization) multivariate analysis of variance
(MANOVA) on participants’ responses on the two items, which revealed a main effect of
When The Going Gets Tough… 41
visualization, F(1, 117) = 64.93, p < .001, η p2 = .36. On average, the person who was visualized in
the demanding condition was perceived as more demanding than the person who was visualized in
the accepting condition (M = 5.59 vs. M = 3.40). (We report averaged scores to facilitate
interpretation.) The analysis also yielded a main effect of orientation, F(1, 117) = 6.62, p < .02, η p2
= .05. State-oriented participants rated the visualized person as more demanding than action-
oriented participants (M = 4.74 vs. M = 4.14). The interaction between orientation and visualization
was not significant, F(1, 117) = 1.76, p = .19, η p2 = .02.
Recognition Times. Following Goschke and Kuhl (1993), we first eliminated errors (i.e., the
number of script words that were not recognized, 16.2% of all responses) and responses lower than
300 ms (1.6% of all responses). Analyses on recognition latencies were conducted on log-
transformed data to normalize the distribution (Ratcliff, 1993). To facilitate interpretation, we report
untransformed means in ms.
We proceeded by subtracting average recognition latencies for words from the prospective
script from average recognition latencies for words from the neutral script. The resulting difference
scores index the intention superiority effect, that is, better memory for prospective script words
compared to neutral script words. A 2 (orientation: action vs. state) x 2 (visualization: demanding
vs. accepting) ANOVA confirmed the predicted two-way interaction effect between orientation and
visualization, F(1, 114) = 10.59, p < .002, η p2 = .09. Relevant means are displayed in Table 2.2.
Action-oriented participants displayed a larger intention superiority effect in the demanding
condition than in the accepting condition, F(1, 114) = 6.20, p < .02, η p2 = .06 (M = 121 vs. M = -
71). Simple t-tests revealed a significant intention superiority effect among action-oriented
participants in the demanding conditions, t(26) = 2.86, p < .009, but not in the accepting condition, t
< 1. By contrast, state-oriented participants had a smaller intention superiority effect in the
demanding condition than in the accepting condition, F(1, 114) = 4.40, p < .04, η p2 = .04 (M = -47
vs. M = 105). Simple t-tests revealed a significant intention superiority effect among state-oriented
When The Going Gets Tough… 42
participants in the accepting condition, t(33) = 2.53, p < .02, but not in the demanding condition, t <
1.
Another way of interpreting the (orientation) x (visualization) interaction is to note that, in
the demanding condition, action-oriented participants showed a larger intention superiority effect
than state-oriented participants, F(1, 114) = 4.05, p < .05, η p2 = .03 (M = 121 vs. M = -47). In the
accepting condition, we found a significant reversal of the pattern. Specifically, action-oriented
participants displayed a lower intention superiority effect than state-oriented participants, F(1, 114)
= 6.72, p < .02, η p2 = .06 (M = -71 vs. M = 105).
Supplementary Analyses on Recognition Times. Additional analyses revealed that the effects
on recognition latencies remained intact when we statistically controlled for error rates.
Furthermore, the examination of intention memory effects during the practice task revealed that
action-oriented (M = 83) and state-oriented participants (M = 84) had similar intention memory
effects under such neutral conditions, F < 1. When we included intention memory during the
practice task as a covariate, the (orientation) x (visualization) interaction on intention memory
during the actual task remained significant.
Recognition Accuracy. Following Goschke and Kuhl (1993), we computed from the hit rates
and false-alarm rates a discriminability index A’ that was proposed by Pollack (1970) as a non-
parametric equivalent to d’, and that can be calculated even when the number of observations is
small. Chance performance is reflected by an A’ value of .5, whereas perfect performance yields an
A’ of 1.0. For each participant, we calculated A’ separately for neutral and prospective words.2.4
Discriminability indices A’ were subjected to a 2 (orientation) x 2 (visualization) x 2 (script type:
prospective vs. neutral) ANOVA with repeated measures on the last factor. This analysis yielded
only a significant main effect for Script Type; F(1, 114) = 11.20, p < .002. Specifically, A’ values
for prospective words were higher (A’ = .81) than A’ values for neutral words (A’ = .78). The
analysis revealed no effects of orientation or visualization, all Fs < 1.

Discussion
The results of Study 2 confirmed that action versus state orientation moderates the impact of
situational demands on intention memory. Action-oriented participants displayed a significant
intention superiority effect after priming a demanding but not after priming an accepting
relationship. Among state-oriented participants, however, this pattern was reversed such that state-
oriented participants displayed a significant intention superiority effect after priming an accepting
but not after priming a demanding relationship. The results can also be interpreted separately by
demand condition. After priming a demanding relationship, action-oriented participants thus had a
greater intention memory effect than state-oriented participants, whereas the reverse was true after
priming an accepting relationship.
Notably, intention superiority effects between action- and state-oriented participants did not
differ during the practice task. Because demand was not yet manipulated before the practice task,
this lack of an effect suggests that action- versus state-oriented individuals do not differ in intention
memory under neutral conditions. Moreover, a covariance analysis revealed that that the effects of
demand on intention memory were independent from individual differences in intention memory
under neutral conditions. Of course, such interpretations should be made with caution, given the
inherent difficulties in drawing conclusions from null findings.
Our manipulation checks found that state-oriented participants perceived the visualized
person in both conditions as somewhat more demanding compared to action-oriented participants.
Even though this effect was not anticipated, it could not explain the observed effects of action
versus state orientation on intention memory. First, effects of action versus state orientation on
intention memory were moderated by situational demands, and no such moderation effect was
obtained on the manipulation check. Second, when we included the manipulation check as a
covariate, the (orientation) x (visualization) interaction on intention memory remained significant.
When The Going Gets Tough… 44
General Discussion
Past research and theorizing have described inconsistent effects of demands on working
memory capacity. On the one hand, research has found that working memory is prone to "choking
under pressure" (Baumeister, 1984), in that people utilize their working memory capacity less
efficiently in demanding situations. On the other hand, recent notions on top-down control
processes suggest that high demands may serve as a mobilization signal to utilize working memory
capacity more efficiently (e.g., Botvinick et al., 2001). The present research suggests that these
apparent inconsistencies can be resolved by considering the role of action versus state orientation as
a moderator of the effects of situational demands. The choking pattern is more characteristic of
state-oriented individuals, who utilize their working memory capacity less efficiently with
increasing demands. The mobilization pattern, on the other hand, is more characteristic of action-
oriented individuals, who better utilize their working memory capacity with increasing demands.
In two studies, action-oriented participants utilized their working memory capacity more
efficiently after visualizing a demanding relationship compared to an accepting relationship. State-
oriented participants displayed the opposite pattern: they had less working memory capacity
available after visualizing a demanding relationship compared to an accepting relationship. Stated
differently, action-oriented participants better utilized their working memory capacity than state-
oriented participants after visualizing a demanding relationship, whereas the reverse was true after
visualizing an accepting relationship. These effects were robust across two very different measures
of working memory capacity, i.e., OSPAN (Study 2.1) and intention memory (Study 2.2). Taken
together, the present research highlights the importance of action versus state orientation in the use
of working memory capacity under varying levels of situational demand.
Why would working memory choke under high demands among state-oriented individuals?
Presumably, state-oriented individuals’ tendency towards indecisiveness and hesitation (Kuhl,
1984) renders them less capable of updating their working memory. Consequently, state-oriented
When The Going Gets Tough… 45
individuals will be unable to terminate the sustained working memory load that is induced by high
demanding conditions. This, in turn, leaves less working memory capacity available for subsequent
tasks. Under low demanding conditions, working memory is less loaded than under high demanding
conditions. Consequently, it is less relevant to update working memory under low demanding
conditions. Moreover, low demanding conditions can even help state-oriented individuals to update
their working memory, particularly when conditions are rewarding. Visualizing an accepting
relationship likely provided such rewarding context, thereby making more working memory
capacity available for state-oriented individuals to use in subsequent tasks.
Unlike their state-oriented counterparts, action-oriented participants better utilized their
working memory capacity under high compared to low demanding conditions. A likely explanation
for this pattern is that action-oriented individuals have a tendency towards decisiveness and
initiative (Kuhl, 1984), which renders them more capable of updating the contents of their working
memory. Under high demands, action-oriented individuals are more inclined to update working
memory, thereby making more working memory capacity available for subsequent tasks. By
contrast, low demanding conditions do not trigger compensatory updating of working memory
among action-oriented individuals and thus do not lead to more efficient use of working memory
capacity. Moreover, action-oriented individuals are less receptive to rewarding contexts than state-
oriented individuals (Koole et al., 2005). Consequently, visualizing an accepting person does not
necessarily facilitate working memory among action-oriented individuals.
Action-oriented individuals thus utilize their working memory capacity most efficiently
under demanding conditions, whereas state-oriented individuals utilize their working memory
capacity most efficiently under rewarding or accepting conditions. This overall pattern suggests that
having an action orientation is more compatible with a demanding context, while having a state
orientation is more compatible with a rewarding or accepting context. Despite the observed
advantage of state-oriented individuals under rewarding conditions, however, it is important to note
When The Going Gets Tough… 46
that rewarding or accepting conditions may be often lacking in common situations such as at work
or during one’s study (cf. Diefendorff et al., 1998). Accordingly, action orientation may prove more
advantageous than state orientation in many achievement contexts.
The present research further highlights the role of relationship schemas for the regulation of
basic cognitive processes. Previous work has shown that priming relationship schemas activates
correspondent goal representations and expectations (e.g., Fitzsimons & Bargh, 2003; cf. Chen et
al., 2006). The present findings add to this literature that relationship schemas even influence the
efficiency of basic memory functions such as working memory capacity. The present research thus
reveals an important connection between interpersonal and intrapersonal processes (cf. Vohs &
Finkel, 2006).
Limitations and Avenues for Future Research
The present research has several limitations and thus leaves important issues open for further
investigation. First, unlike previous research (e.g., Van der Linden et al., 2003), we did not find
main effects of demands on measures of working memory capacity. Previous research did not
include measures of action versus state orientation. It is thus possible that previous research has
unwittingly relied on either predominately state-oriented or predominately action-oriented samples.
It is equally conceivable that previous manipulations have induced much different levels of demand
than the present visualization manipulation. For instance, Van der Linden and colleagues (2003)
had participants engage in a demanding task for two hours. It seems likely that even action-oriented
individuals use their working memory capacity less efficiently under such extreme demands.
Another important issue concerns the regulation of working memory capacity under
threatening conditions. Previous research has found that people utilize their working memory
capacity less efficiently as a result of stereotype threat (Schmader & Johns, 2003) and math anxiety
(Ashcraft & Kirk, 2001). However, theoretical considerations suggest that people may be able to
convert feelings of threat into feelings of challenge under conditions that potentially jeopardize their
When The Going Gets Tough… 47
self-image or well-being (Blascovich & Mendes, 2000). Based on PSI theory (Kuhl, 2001), we
suggest that action versus state orientation on the threat-related dimension (AOT) may be an
important moderator of working memory capacity under threat. Specifically, threat-related action
orientation may lead to the mobilization of working memory capacity under conditions of
stereotype threat or math anxiety, whereas threat-related state orientation may lead to choking under
pressure. Future research may explore this intriguing possibility.
Concluding Remarks
Working memory is a vital psychological function that allows people to remember important
information even when they are temporarily distracted. Past research and theorizing has made
inconsistent predictions whether working memory capacity is utilized more efficiently or less
efficiently under high situational demands. In the present research, we have suggested that these
conflicting notions can be reconciled by considering the role of action versus state orientation. In
particular, action-oriented individuals used their working memory capacity most efficiently under
high demanding conditions, whereas state-oriented individuals used their working memory capacity
most efficiently under low demanding conditions. The present research thus illuminates how
different individuals dynamically regulate the waxing and waning of working memory.

Chapter 3
Affective Shielding:
Subliminal Affect Regulation among Action- versus State-Oriented Individuals3.1
People sometimes feel good or bad without knowing exactly where these feelings come
from. As experimental research suggests, affective reactions can be triggered by subliminal stimuli
that are presented entirely outside of conscious awareness (Zajonc, 2000). Subliminally triggered
affect has been found to exert a pervasive influence on mood, evaluative judgments, social
information processing, and behavior (Chartrand, Van Baaren, & Bargh, 2006; Stapel, Koomen, &
Ruys, 2002; Winkielman, Berridge, & Wilbarger, 2005). Given that affective reactions sometimes
interfere with people’s goal pursuits (Carver & Scheier, 1990), however, it seems important that
people are able to regulate their affective reactions even if these are triggered subliminally. In
Chapter 3, we examine the role of action vs. state orientation (Kuhl, 1981) in the regulation of
subliminally triggered affect. Specifically, we test the notion that action-oriented individuals are
better able to resist the influence of subliminally triggered affect compared to state-oriented
individuals.
Feelings without a Cause: Evidence from Subliminal Priming Research
In recent years, it has become increasingly evident that affective reactions can be based on
only minimal cognitive processing and often even elude people’s conscious awareness. Several
lines of investigation have demonstrated that such “basic affective reactions” (Winkielman et al.,
2005) can be triggered by subtle changes in the environment (Duckworth, Bargh, Garcia, &
Chaiken, 2002), simple body movements (Cacioppo, Priester, & Berntson, 1993), or physical
postures (Stepper & Strack, 1993). Throughout these different kinds of affect inducements, people
typically remain unaware of the source of their affective reactions. Indeed, it appears that basic
affective reactions are often diffuse and free-floating, and “spill over” into people’s experience of
other stimuli that happen to come along (Zajonc, 2000). Moreover, basic affective reactions can
When The Going Gets Tough… 49
influence behavioral initiative (Hertel & Hardin, 1990), or direct behavioral tendencies towards
approach and avoidance (Chen & Bargh, 1999; Gray, 2001; Neumann, Förster, & Strack, 2003).
Some of the most compelling demonstrations of basic affective reactions can be found in the
literature on subliminal affective priming (for recent reviews, see Berridge & Winkielman, 2003;
Zajonc, 2000). In subliminal affective priming research, participants are first exposed to positive or
negative affective stimuli for very brief durations that preclude conscious detection. After this
initial exposure, participants’ affective reactions are assessed. A pioneering set of studies on
subliminal affective priming was conducted by Murphy and Zajonc (1993). In these studies,
participants were subliminally primed with human faces expressing either happiness or anger.
Following exposure to these subliminal primes, participants had to express their preferences for
unfamiliar Chinese ideographs. Results showed that participants rated ideographs more favorably
when the prime was a happy rather than an angry face. Notably, no affective priming effects
occurred when participants could consciously perceive the happy and angry face primes.
The foregoing paragraphs suggest that the affective system is functionally different from,
and operates independently of, conscious cognitive processing. In line with this notion,
psychological and neurophysiological research has established that basic affective reactions occur
early on in the information processing sequence, and can be triggered with minimal stimulus input
(Berridge & Winkielman, 2003; Zajonc, 2000). Moreover, subliminal affective priming effects
seem to be resistant to attempts at conscious control (Winkielman, Zajonc, & Schwarz, 1997).
The theoretical relevance of subliminal affective priming research extends beyond the
laboratory. In everyday life, people often do not recognize the causes of their affective reactions.
For instance, people show clear affective reactions in response to the weather, even though they
often fail to identify the weather as a cause of their reactions (Schwarz & Clore, 1983). In principle,
people can realize that stimuli such as the weather have influenced their affective states.
Oftentimes, however, the causes of people's affective reactions remain inaccessible to them (Wilson
When The Going Gets Tough… 50
& Dunn, 2004). People’s minds would possibly be overstrained if the causes for each separate
affective reaction had to be processed on a conscious level. In real life, therefore, it seems likely
that people experience many affective states without knowing their cause. Subliminal affective
priming research may thus provide a window into the nature of basic affective reactions that are
common in everyday life.
Research further suggests that subliminal affective priming can have important downstream
consequences. In many cases, subliminally triggered basic affect does not outlive a second or so
(Murphy & Zajonc, 1993). However, when people encounter sequences of stimuli that are more
consistently positive or negative, subliminal affective priming may accumulate and thereby become
more durable (Chartrand et al., 2006, Stapel et al., 2002; Winkielman et al., 2005). Furthermore, the
effects of subliminal affective priming extend to cognitive and behavioral processes. For instance,
subliminal affective priming has been found to influence stereotyping (Chartrand et al., 2006), as
well as motivational responses such as consumption behavior (Winkielman et al., 2005). Taken
together, these findings suggest that subliminally triggered affect plays an important role in guiding
cognition and behavior.
Action Orientation and Affect Regulation
It is conceivable that basic affective reactions that are triggered by subliminal affective
priming may sometimes impede goal-directed behavior (cf. Carver & Scheier, 1990). To the extent
that basic affect triggers behavioral tendencies (e.g., approach or avoidance) that are incompatible
with people’s current goals, it is important for people to exert some level of control over this type of
affect. For instance, worsened basic affect may activate behavioral avoidance tendencies (Gray,
2001) that interfere with the person’s intention to take initiative (Hertel & Hardin, 1990). Shielding
one’s intentions thus seems to require control over one's basic affective reactions.
How might people control subliminally triggered affect? Given the unconscious nature of
basic affect, it is likely that its regulation also largely operates at unconscious levels. From this
When The Going Gets Tough… 51
perspective, the control of subliminally triggered affect may be achieved when automatic affective
responses (e.g. dejection caused by a rainy morning) can be overridden in favour of a more adaptive
affective response (e.g., cheering up to get a hard day’s work done). Similar to the cognitive control
of behavior (Norman & Shallice, 1986), the regulation of basic affect requires the activation of
higher cortical functions (e.g., prefrontal cortex) in order to override inappropriate affective
reactions (Kuhl, 2000).
The regulation of basic affect has been addressed by Personality Systems Interactions (PSI)
theory (Kuhl, 2000). According to PSI theory, people are capable of regulating basic affective
reactions, even when they are unaware of their precise causes. This type of affect regulation is
referred to as intuitive affect regulation (Koole & Jostmann, 2004). PSI theory further suggests that
the functional basis for intuitive affect regulation is provided by extension memory, which is
conceived of as a central executive system linked to the prefrontal cortex that provides integrated
knowledge about the self and the environment. If the person responds to worsened basic affect with
the activation of extension memory, affect becomes modulated so that it is congruent with the
person’s current goal intentions, personal motives, and contextual constraints. Because extension
memory provides rapid processing of vast amounts of complex information, its workings do not
necessarily require the involvement of the conscious mind. In principle, intuitive affect regulation
pertains to both positive and negative affect. However, since goal-directed behavior is most
impeded by negative affect (Simon, 1967), intuitive affect regulation is likely to be stronger when
basic affect is worsened rather than when it is improved.
Aided by intuitive affect regulation processes, people can pursue their goals even in the face
of worsened basic affect. However, people do not invariably engage in intuitive affect regulation.
According to PSI theory (Kuhl, 2000), worsened basic affect triggers either a meta-static (change-
oriented) or a cata-static (change-preventing) mode of regulation. During the meta-static mode of
regulation, individuals are likely to activate central executive functions that promote intuitive affect
When The Going Gets Tough… 52
regulation and goal-directed action. Therefore, the meta-static mode is referred to as action
orientation. By contrast, during the cata-static mode, central executive functions and intuitive affect
regulation are likely to be inhibited. Instead, individuals are more likely to become preoccupied
with their current states while in a cata-static mode. The cata-static mode is therefore referred to as
state orientation. Taken together, action versus state orientation are mutually exclusive regulatory
modes that become triggered under conditions of worsened basic affect.
Whether a person is more likely to become action-oriented or state-oriented in response to
worsened basic affect depends in part on stable individual differences (Kuhl, 2000). Based on their
prior experiences with situations that cause significant changes in basic affect (i.e., demanding or
threatening situations), some individuals may have learned to react in a predominantly action-
oriented manner under conditions of worsened basic affect. By contrast, other individuals may have
developed a tendency to react in a state-oriented manner when basic affect becomes more negative.
In line with this reasoning, Kuhl (1981, 1994b) developed a self-report scale to assess individual
differences in action versus state orientation. Based on their scores, some people can be
characterized as predominantly state-oriented, whereas others can be characterized as
predominantly action-oriented (for reviews and construct validity, see Diefendorff, Hall, Lord, &
Strean, 2000; Kuhl & Beckmann, 1994a).
Research has gathered ample evidence that individual differences in action versus state
orientation are closely linked to intuitive affect regulation. A first line of research has addressed the
physiological and behavioral consequences of intuitive affect regulation. For instance, Heckhausen
and Strang (1988) observed increased physiological response (i.e., lactate concentration) and
decreased athletic performance among state-oriented basketball players under performance
pressure, whereas action-oriented players displayed no such effect in response to performance
pressure. In a similar vein, Kuhl (1981) found performance decrements on a complex cognitive task
after repeated failure experiences among state-oriented but not among action-oriented participants.
When The Going Gets Tough… 53
Furthermore, a negative mood impaired complex coherence judgments among state-oriented but not
among action-oriented individuals (Baumann & Kuhl, 2002). Finally, Jostmann and Koole (2006;
Chapter 4) demonstrated that the induction of high demands diminished cognitive control, as
indicated by the performance on the Stroop color evaluation task and related paradigms, among
state-oriented individuals but not among action-oriented individuals.
A second line of research has focused more directly on the affective consequences of action
orientation. Specifically, action-oriented individuals reported less unpleasant feelings in response to
repeated failure experiences (Brunstein & Olbrich, 1985). In a similar vein, action-oriented
individuals showed less depressive symptoms compared to state-oriented individuals, especially
when levels of stress were high (Rholes, Michas, & Shroff, 1989). Furthermore, increases in action
orientation predicts whether phobic patients can overcome their phobic fears (Schulte, Hartung, &
Wilke, 1997).
Koole and Jostmann (2004, Study 1) examined the temporal dynamics of affect regulation in
action- versus state-oriented individuals. In line with prior research (e.g., Brunstein & Olbrich,
1985), action-oriented participants displayed significant down-regulation of tense mood after the
induction of mild stress. More important, however, this down-regulation was not so much apparent
immediately after the induction of stress, but rather when moods were assessed 10 minutes
afterwards. No similar decreases in tension were found when no stress was induced or among state-
oriented participants. This finding supports the notion that action orientation entails efficient down-
regulation rather than a decreased sensibility towards aversive affect.
Finally, research has begun to investigate how action orientation regulates basic affective
reactions without relying on explicit affect measures. Specifically, Koole and Jostmann (2004,
Study 2) examined the effects of action orientation in an affective Simon task. In this task,
participants were required to provide a positive or negative response to a target stimulus on the
basis of a non-affective stimulus feature (e.g., grammatical status). Although the valence of the
When The Going Gets Tough… 54
target stimulus was irrelevant and should be ignored during the task, participants displayed an
“affective Simon effect” (De Houwer & Eelen, 1998), i.e., they gave faster responses and made less
errors when the valence of the target stimulus was congruent with the valence of the response.
However, when the affective Simon task was preceded by the induction of mild stress, action-
oriented participants were faster and made less errors compared to state-oriented participants on
trials that required them to give positive responses to negative targets. This effect was interpreted as
an up-regulation of worsened basic affect evoked by the prior induction of mild stress. Taken
together, these findings suggest that action orientation can regulate basic affective reactions. It
remains to be seen, however, whether action orientation can also regulate basic affective reactions
that are triggered subliminally.
The Present Research and Hypotheses
We designed the present research to examine the link between action orientation and
regulation of subliminally triggered basic affect. To address this issue, we used a subliminal
parafoveal priming paradigm (Chartrand & Bargh, 1996) to prime action-oriented and state-oriented
participants with schematic drawings of angry, neutral, or happy human faces (Öhman, Lundqvist,
& Esteves, 2001). These stimuli are displayed in Figure 3.1.
Angry Happy Neutral
Figure 3.1. Experimental Stimuli used as Subliminal Affective Primes
(Adapted from Öhman et al., 2001).
We assumed that the schematic faces have an intrinsic affective value to people that is
similar for action- and state-oriented individuals. To test this assumption, we conducted a pilot
study (N = 59). In this study, action-oriented and state-oriented participants indicated to what extent
When The Going Gets Tough… 55
they perceived the happy, neutral, and angry faces as being negative, disapproving, and aggressive
(1 = not at all, 9 = very much). Action-oriented and state-oriented participants’ evaluations of the
happy and angry faces did not differ, all Fs < 1. Furthermore, the two groups evaluated the neutral
face similarly as negative and disapproving, Fs < 1. The only statistically detectable difference lies
in the perceived aggressiveness of the neutral face, F(1, 57) = 4.85, p < .05. State-oriented
participants found the neutral face more aggressive than action-oriented participants, M = 5.00 vs.
M = 3.97, respectively. Overall, we concluded that action-oriented and state-oriented individuals do
not differ in their evaluation of the prime stimuli.
In the parafoveal priming task, participants were subliminally exposed to angry, or neutral,
or happy schematic faces. The exposure time for each face was 30 ms, which has been shown to be
below the level of conscious awareness in this task (Chartrand & Bargh, 1996). After the subliminal
priming task, participants completed a preference judgment task to measure basic affect (Tesser,
Millar, & Moore, 1988).
Our main hypothesis was that action orientation would regulate the effects of subliminal
affective priming on basic affective reactions. More specifically, we expected that subliminal
affective primes would evoke congruent reactions among state-oriented participants, such that
subliminal priming of angry faces would lead to lower basic affect compared to subliminal priming
of happy faces. By contrast, we expected no such priming effects among action-oriented
participants. As regards subliminal priming of neutral faces, we expected that basic affective
reactions in response to those faces would lie in between responses to angry and happy faces.
Study 3.1
Method
Participants and Design
Ninety-two paid volunteers at the Free University of Amsterdam (33 men and 59 women,
average age 20) participated in the study. The design was 2 (action orientation: action vs. state;
When The Going Gets Tough… 56
between participants) x 3 (prime valence: happy vs. neutral vs. angry; between participants).
Participants were randomly assigned to the experimental conditions (happy: N = 31; neutral: N =
30; angry: N = 31). The dependent variable consisted of participants’ mean ratings on the basic
affect measure.
Procedure
Upon arrival in the laboratory, participants were led to individual cubicles each containing
an Apple Macintosh (iMac) computer. Experimental instructions were administered via computer-
program. Participants were first informed that they would complete a series of unrelated tasks,
which were ostensibly administered together for efficiency reasons. Participants first completed a
study on “personality”, which contained a Dutch translation of the Action Control Scale (ACS-90;
Kuhl, 1994b). The ACS-90 served as our measure of individual differences in action versus state
orientation. On completion of the ACS-90, participants moved on with a parafoveal priming task, in
which happy, angry, or neutral faces were presented outside of conscious awareness. Participants
were told that very brief flashes would appear at unpredictable places and times, and that their task
was to decide whether a flash appeared on the left side or the right side of the screen. Immediately
after the parafoveal priming task, participants completed a preference judgment task to measure
basic affect. Next, participants moved on to some unrelated filler tasks, which lasted about fifteen
minutes. Finally, participants continued with a funneled debriefing procedure (Chartrand & Bargh,
1996), after which they were thanked for their efforts and paid.
Independent Variables
Individual Differences. The ACS-90 (Kuhl, 1994b) measures two interrelated but
conceptually independent types of action versus state orientation: first, the capacity to initiate goal-
directed action under high demands (demand-related action orientation, AOD), and second, the
capacity to engage in goal-directed action in response to threatening experiences (threat-related
action orientation, AOT). According to PSI theory (Kuhl, 2000, 2001, p. 243), threat and demand
When The Going Gets Tough… 57
represent qualitatively different types of aversive affective states, each requiring a specific form of
intuitive affect regulation.
In the present research, we administered two 12-item subscales of the ACS-90, which
respectively measure AOD and AOT. The items of both subscales were intermingled and presented
in a different random order for each participant. Each of the items describes a stressful situation,
and an action-oriented versus state-oriented way of coping with that situation. For each item,
participants were asked to select the response that best described their own reaction to that situation.
An example item of the AOD subscale is “When I know that I must finish something soon: A. I
have to push myself to get started. B. I find it easy to get it done and over with”. An example item
of the AOT subscale is “When I am being told that my work is completely unsatisfactory: A. I feel
paralysed. B. I don’t let it bother me for too long.” In both example items, A represents a state-
oriented response, and B represents an action-oriented response. Action-oriented responses were
coded as “1”, whereas state-oriented responses were coded as “0”. Scores were then summed for
each subscale. Participants who gave 7 or more action-oriented responses on the AOD scale were
classified as action-oriented (N = 45), whereas participants with less then 7 action-oriented
responses were classified as state-oriented on that subscale (N = 47). An identical procedure was
followed for the AOT scale, N = 34 vs. N = 58, respectively.3.2
A priori, we had no strong predictions on whether the subliminal priming procedure would
primarily evoke effects of AOD or AOT. To the extent that the angry faces would be perceived as
threatening (Öhman et al., 2001), we would expect to find effects of AOT rather than AOD.
However, the angry faces that were used in the present study had a closed mouth with a downward
curve, whereas threat is much more strongly associated with an open mouth with bared teeth
(Aronoff, Barclay, & Stevenson, 1988). A closed mouth in a downward curve has been found to
signal strong negativity but only moderate activity (Lundqvist, Esteves, & Öhman, 1999). In view
of these considerations, it seems possible that the angry faces would signal disapproval rather than
When The Going Gets Tough… 58
threat, which would lead one to expect effects of AOD rather than AOT. In the remainder of this
chapter, we will generally refer to the broader term “action orientation” rather than to its specific
subcategories unless a more precise distinction is required for clarification.
Subliminal Affective Priming. The parafoveal priming task was modelled after Chartrand
and Bargh (1996). The priming task was introduced to participants as a study on reaction speed to
visual stimuli. We instructed participants to react as quickly and as accurately as possible to brief
flashes that appeared at various locations on the computer screen. When a flash appeared on the left
side of the screen, participants were to press a green key on the left side of the keyboard. When a
flash appeared on the right side of the screen, they were to press a red key on the right side of the
keyboard. Participants were told that the flashes would appear at unpredictable times and locations,
and that the best strategy would be to keep their eyes on a fixation point in the center of the screen.
Before participants started with the actual task, they were given five practice trials. During the
practice trials, no faces were primed. During the following 24 experimental trials, participants were
subliminally primed with happy, or angry, or neutral faces. Each face prime was presented for 30
ms, and was immediately followed by a 100 ms mask consisting of dots and lines. No feedback was
given to the participants regarding their performance during the parafoveal priming task (for more
details regarding the parafoveal priming task, see Chartrand & Bargh, 1996).
Basic Affect Measure
Our measure of basic affect was adapted from Tesser et al. (1988). Participants were
informed that the next study was on the aesthetic evaluation of words. They were to evaluate the
pleasantness of some non-existing words on a scale ranging from 1 (unpleasant) to 7 (pleasant).
Only the two anchors of the scale were labeled. Participants were told that the experimenters had
chosen non-existing words in order to avoid disturbing influences of word meaning. Participants
were instructed not to spend too much time on the evaluation and to simply report their first
When The Going Gets Tough… 59
reactions. The three non-existing words (“pleban”, “lempon”, “tokitorer”; Stapel, 2002) were shown
in random order for each participant.
Awareness Check
At the end of the experimental session, we assessed whether participants had been aware of
the priming procedure. We used a funneled debriefing procedure (Chartrand & Bargh, 1996) in
which participants were asked questions about the study with increasing specificity. First,
participants had to indicate what they thought had been the purpose of the tasks they had performed.
Next, they were asked to indicate whether they thought that the tasks were related to each other, and
whether anything about the study seemed strange or suspicious to them. Finally, participants were
asked to indicate what they had seen during the flashes. No participants guessed the real purpose of
the experiment, neither did they report being suspicious about the priming procedure. The majority
of participants (92.4 % of the entire sample) reported to have seen something unrelated to the prime
stimuli (e.g., a pattern of lines). Seven participants (7.6 % of the entire sample), however, reported
that they had seen a head, a face, or a smile during the flashes. These participants were excluded
from further analysis.

Results
Reliability coefficients for AOD (Kuder-Richardson (KR) 20 coefficient = .70) and AOT
(KR 20 coefficient = .73) were satisfactory. We only report effects on AOD, since all effects on
AOT were non-significant (all Fs < 1). Reliability for our basic affect measure was unacceptably
low (Cronbach’s alpha = .21). Therefore, we decided to conduct both multivariate analyses with the
three single implicit affect items as separate dependent variables, as well as univariate analyses with
the averaged overall basic affect scale as a dependent variable.3.3
Both analytic strategies yielded similar results. Specifically, a 2 (action orientation: action
vs. state; between participants) x 3 (prime valence: angry vs. neutral vs. happy; between
participants) multivariate ANOVA with three basic affect scores as dependent variables yielded a
significant interaction between action orientation and prime valence, F(6, 154) = 2.56, p < .03.
Likewise, a 2 (action orientation: action vs. state; between participants) x 3 (prime valence: angry
vs. neutral vs. happy; between participants) univariate ANOVA with participants’ averaged basic
affect ratings as dependent variable revealed a significant interaction between action orientation and
prime valence, F(2, 79) = 4.46, p < .05, η2 = .10. To facilitate the interpretation of the effect,
however, we report only the simple analyses on the averaged overall basic affect scale. Relevant
means are displayed in Table 3.1.
LSD post hoc analyses revealed that prime valence had a significant effect on basic affect
among state-oriented participants, F(2, 79) = 4.40, p < .05, η2 = .10. More specifically, subliminal
priming with happy faces resulted in higher basic affect compared to subliminal priming with
neutral (p < .05), or angry faces (p < .01), M = 4.24 vs. M = 3.44 vs. M = 3.17, respectively.
However, prime valence had an opposite, albeit nonsignificant, effect on basic affect among action-
oriented participants, F(2, 79) = 1.01, p > .2. Subliminal priming with happy faces resulted in
slightly lower basic affect among action-oriented participants compared to subliminal priming with
neutral or angry faces, M = 3.50 vs. M = 3.71 vs. M = 4.04, respectively.
When The Going Gets Tough… 61
An alternative way to interpret the results is to note that subliminal priming with angry faces
resulted in lower basic affect among state-oriented participants compared to action-oriented
participants, F(1, 79) = 4.76, p < .05, η2 = .06. By contrast, subliminal priming with neutral faces
did not yield any differences in basic affect between state-oriented and action-oriented participants,
F < 1. Finally, subliminal priming with happy faces resulted in marginally higher basic affect
among state-oriented participants compared to action-oriented participants, F(1, 79) = 3.86, p =
.053, η2 = .05.
Additional analyses revealed that performance during the parafoveal priming task had no
effect on basic affect ratings. More specifically, when we reran the analyses with the average
number of incorrect responses during the parafoveal priming task (3.8 %) and participants’ mean
response times for each trial (334 ms) as covariates, all results remained intact.
Discussion
Past research has shown that subliminal affective priming can have a significant impact on
people’s basic affective reactions (Chartrand et al., 2006; Murphy & Zajonc, 1993; Stapel et al.,
2002; Winkielman et al., 2005). In the present chapter, we explored whether action-oriented
individuals are capable of regulating subliminally triggered basic affect. Our results showed that
subliminal affective priming effects were only found among state-oriented participants. By contrast,
action-oriented participants’ basic affective responses were not influenced by subliminal affective
priming. Indeed, action-oriented participants displayed higher basic affect compared to state-
oriented participants in response to priming with angry faces. Taken together, the present research
provides evidence that action-oriented individuals are able to regulate subliminally triggered basic
affect.
The present findings add to prior research that has demonstrated efficient down-regulation
of basic affect among action-oriented individuals (Koole & Jostmann, 2004). In this prior
demonstration, however, the affect eliciting stimuli were consciously accessible to the participants.
When The Going Gets Tough… 62
The present study is thus the first to show that action orientation promotes affect regulation even
when the source of the affective reaction remains unrecognized. This finding is notable because
prevalent theorizing has suggested that subliminal affective reactions unfold early during stimulus
perception and relatively unimpeded by top-down processes (Zajonc, 2000). Moreover, prior
research has shown that subliminally elicited basic affect resists conscious interventions
(Winkielman et al., 1997).
How can we reconcile the present findings with existing ideas about the nature of
subliminally elicited basic affect? PSI theory (Kuhl, 2000) suggests that action-oriented individuals
regulate their affective states so that affect facilitates goal-directed behavior. Goal-directed behavior
is served best when individuals do not suppress any affective signal that comes along but remain
susceptible to potential opportunities and dangers (Carver & Scheier, 1990). In line with this
assumption, prior research has shown that intuitive affect regulation among action-oriented
individuals does not interfere with automatic vigilance for negative affect (Koole & Jostmann,
2004, Study 3). Consequently, the present finding does not challenge the idea that basic affective
reactions unfold early during stimulus perception (Zajonc, 2000). However, the present finding does
suggest that people are able to exert control over these basic affective reactions. This control over
basic affect is likely to rely on unconscious processes (Kuhl, 2000) rather than on conscious
attribution (Winkielman et al., 1997).
Subliminal affect regulation seems adaptive for several reasons. First, subliminal affect
regulation allows people to control basic affective reactions without knowing their cause. Second,
subliminal affect regulation presumably does not rely on the limited capacity of the conscious mind.
As a consequence, people are likely to regulate affective reactions that are triggered by more than
one single cause. The present research has shown that action-oriented individuals can regulate
affective reactions that are caused by repeated subliminal exposure to the same (aversive) stimulus.
Although it remains to be examined by future research, we can speculate that action orientation may
When The Going Gets Tough… 63
not only shield against the affective consequences of a rainy morning (Schwarz & Clore, 1983), but
also against the scowling faces caught up in the same morning’s traffic jam.
Limitations and Future Perspectives
The present research is still preliminary and leaves several questions unanswered. First, in
line with PSI theory (Kuhl, 2000) our suggestion was that action-oriented participants actively
regulate their basic affective reactions. Although this assumption has been confirmed in prior
research (Koole & Jostmann, 2004), it was not directly tested in the present investigation. Future
research on subliminal affect regulation should therefore include more direct measures of affective
regulation (e.g., affective Simon task) as well as pretest measures of basic affect.
Second, the present findings differ from prior research, which has consistently found main
effects of subliminal affective priming rather than an interaction between subliminal affective
priming and action orientation (e.g., Murphy & Zajonc, 1993; Stapel et al., 2002). Prior research
has not controlled for individual differences in action orientation, which renders speculations about
its role during these studies difficult. One possible explanation for the inconsistency between
studies is that prior research has unwittingly relied on observations of predominantly state-oriented
samples. This corresponds with the significant main effect of prime valence among state-oriented
participants in the present research.
An alternative explanation would be that the difference between our reseach and prior work
is due to differences in the situational context in which the priming took place. According to PSI
theory (Kuhl, 2000), action-oriented individuals are unlikely to regulate their affective states when
the situational context endorses relaxation. In line with this assumption, basic affective reactions
between action-oriented and state-oriented participants have been found to be similar under relaxing
and accepting circumstances (Koole & Jostmann, 2004). Possibly, the context in which our research
took place endorsed relaxation to a lesser degree compared to prior research. Further research is
When The Going Gets Tough… 64
required to gauge the conditions under which subliminal affect regulation among action-oriented
individuals takes place.
Concluding Remarks
Feelings sometimes arise without any obvious cause. Such basic affective reactions pose a
challenge to people’s affect regulation skills because they can be unpredictable and resistant to
attempts at conscious control. Using a subliminal affective priming paradigm, the present research
was able to show that action orientation may allow people to shield themselves against the intrusion
of basic affective reactions. This capacity for subliminal affect regulation seems a remarkable
human achievement, which may promote goal-directed action even when affect creeps in unnoticed.

Chapter 4
Behavioral Shielding
Action Orientation Moderates the Impact of High Demands
in Stroop Interference Tasks4.1
One of the most remarkable achievements of cognitive functioning lies in people’s ability to
override strong but inappropriate action tendencies. Without such cognitive control, people would
be unable to adapt to novel or complex situations, resist temptations, or inhibit their impulses
(Norman & Shallice, 1986). Cognitive control thus provides flexibility where pre-programmed and
habitual behavior control proves too rigid.
People do not always mobilize the same amount of cognitive control in every situation.
Accordingly, the question arises how cognitive control itself is brought about and regulated
(Monsell, 1996). The regulation of cognitive control has been historically assigned to the proverbial
homunculus, or “little man in the head”. However, an auspicious way to exorcise the homunculus
emerges if one considers the capacity of cognitive control processes to make compensatory
adjustments in response to high demands, or conditions of sustained working memory use. The
basic idea is that high demands leave a person with insufficient amounts of cognitive control to
override inappropriate action tendencies (cf. Lorist, Boksem, & Ridderinkhof, 2005). Such a
shortage in cognitive control, however, may lead to compensatory adjustments to strengthen
cognitive control (cf. Gollwitzer, 1993; Kuhl, 1984). Accordingly, the regulation of cognitive
control may be closely coordinated with the demands of the situation.
In the present research, we further elaborate on the role of high demands in the regulation of
cognitive control. Based on Personality Systems Interactions (PSI) theory (Kuhl, 1984, 2000; Kuhl
& Koole, 2004), we suggest that the effects of demand on cognitive control may depend on whether
individuals are able to activate the adjustment processes necessary for strengthening cognitive
control. Individuals who can adjust flexibly to demanding situations, or action-oriented individuals,
When The Going Gets Tough… 66
are likely to display improved cognitive control under high demands compared to individuals who
are incapable of activating appropriate adjustment processes, or state-oriented individuals (Kuhl,
1994a). In the following paragraphs, we begin by reviewing the existing literature on cognitive
control and action versus state orientation. After this, we present four empirical studies that tested
our theoretical analysis.
Mechanisms of Cognitive Control
Cognitive control (Posner & Snyder, 1975) may be defined as an organization of high-level
executive systems that are responsible for the overriding of strongly activated but situation-
inappropriate action tendencies. Cognitive control thus corresponds to what Miyake and colleagues
(2000, p. 57) denote as “one’s ability to deliberately inhibit dominant, automatic, or prepotent
responses when necessary”. Efficiency at cognitive control is conducive to mental health (Cohen,
Barch, Carter, & Servan-Schreiber, 1999) and healthy life styles (Tiffany, 1990). Moreover,
individual differences in age (Braver et al., 2001), intelligence (Duncan, Emslie, Williams, Johnson,
& Freer, 1996), and working memory capacity (Kane & Engle, 2003) are significantly related to the
functioning of cognitive control. Research has further identified some of the key neural systems that
are related to cognitive control, which include dopamine systems, the prefrontal cortex and the
anterior cingulate cortex (Braver & Cohen, 2000; MacDonald, Cohen, Stenger, & Carter, 2000).
One of the most widely studied paradigms for examining cognitive control is the Stroop
color evaluation task (Stroop, 1935; for a review see MacLeod, 1991). In the typical version of the
task, participants are asked to respond to the ink color in which a word is displayed. Task
performance becomes more difficult when the word meaning refers to a color that is incongruent
with the ink color of the word (e.g., red displayed in blue). Reading the word meaning is a strongly
activated action tendency, even when doing so is task-irrelevant and the word meaning should be
ignored. In the case of incongruent color words, the reading tendency interferes with the task
intention to indicate the ink color as indicated by increased error rates and slower response
When The Going Gets Tough… 67
latencies. The amount of interference during the Stroop task forms a negative indicator of the
amount of cognitive control that people have exerted.
Stroop interference is multiply determined (Kane & Engle, 2003; cf. De Jong, Berendsen, &
Cools, 1999). One set of factors pertains to the strength of the competing action tendency. When the
strength of the competing action tendency exceeds a critical level during incongruent Stroop trials,
performance decrements become more likely. A different set of factors pertains to the accessibility
of the task intention in working memory. In a Stroop task, the task intention includes the instruction
to ignore the irrelevant word color dimension and focus on the ink color dimension instead.
Increased difficulties to maintain a mental representation of the task instruction in working memory
leads to greater response competition between the word color and the ink color dimensions. This
situation is known as goal neglect (Duncan, 1995; cf. Cohen, Dunbar, & McClelland, 1990; De
Jong et al., 1999; Kane & Engle, 2003).
On a neurological level, goal neglect may reflect decreased dopaminergic activity in relevant
brain areas (cf. Braver & Cohen, 2000; Cohen, Braver, & Brown, 2002). Decreased dopaminergic
activity renders the updating of working memory more difficult (Dreisbach et al., 2005) such that
relevant information (e.g., the task intention) cannot be sufficiently maintained while irrelevant
information cannot be erased from working memory. On a phenomenological level, goal neglect is
experienced as insufficient task attention resulting in a weakened goal drive even if the person is, in
principle, capable of performing the task. Notably, goal neglect may leave the ability intact to
retrieve relevant intentions from memory (Luria, 1966). Goal neglect should thus not be equated
with simply forgetting the task intention. Instead, goal neglect can be regarded as difficulty to
initiate cognitive control.
The role of goal neglect in cognitive control has been investigated by manipulating whether
people need to keep the task intention accessible. For instance, in an early study, enhanced
accessibility of the task intention was provided by explicit on-line instructions and resulted in
When The Going Gets Tough… 68
improved cognitive control (Luria & Tsvetkova, 1964). More recently, cognitive control has been
found to improve when trials were presented at a relatively fast compared to a slower pace (De Jong
et al., 1999). Likewise, blocked presentation of incongruent Stroop trials reduced interference
compared to blocks with both incongruent and neutral or congruent trials (Kane & Engle, 2003; cf.
Logan & Zbrodoff, 1979; Long & Prat, 2002). In the aforementioned cases, cognitive control was
prompted either through explicit instructions or through frequent or rapidly paced activation during
preceding trials. Frequent or rapidly paced prompts presumably bring the person into a “high-
control state” (Botvinick, Braver, Barch, Carter, & Cohen, 2001) that reduces the attentional burden
to keep the task intention accessible. As such, goal neglect contributes to interference especially
when no external prompting is available.
Drawing on previous work (Braver & Cohen, 2000; Kuhl, 2000; Lorist et al., 2005;
Schmeichel, Vohs, & Baumeister, 2003), we suggest that people are especially vulnerable to goal
neglect under conditions of sustained working memory use. The use of working memory during
mental operations is effortful and draws on limited energetical resources, which become depleted
after sustained use (cf. Muraven & Baumeister, 2000). Importantly, sustained use of working
memory during task performance may also decrease dopaminergic activity and thus render further
use of working memory difficult. Because cognitive control relies on working memory (Kane &
Engle, 2003), sustained working memory use may undermine cognitive control. In line with this
reasoning, recent findings suggest that cognitive control decrements during sustained task
engagement are caused by the failure to maintain adequate levels of dopaminergic activity in
relevant brain areas (Lorist et al., 2005). In the present context, we refer to conditions of sustained
working memory use as high-demanding and conditions without sustained use as low-demanding.
Cognitive Control under Demand: The Case of Action versus State Orientation
High demands may impair cognitive control under various task conditions. For instance,
sustained engagement in tasks that rely on working memory renders cognitive control more difficult
When The Going Gets Tough… 69
during later phases of the same task (Lorist et al., 2005), or during subsequent tasks (Schmeichel et
al., 2003; Van der Linden, Frese, & Meijman, 2003). Another instance of a high-demanding
condition is the activation of an uncompleted intention in working memory. Because uncompleted
intentions often persist in working memory (cf. Goschke & Kuhl, 1993; Marsh, Hicks, & Bink,
1998), they may cause subsequent cognitive control decrements (Kuhl & Helle, 1986; cf. Kazén &
Kuhl, 2005; Kuhl & Kazén, 1999; Shah, Kruglanski, & Friedman, 2003). Sustained task
engagement and persisting intention activation can also occur outside the laboratory. Indeed, high
demands have been found to undermine performance in academic and athletic settings (e.g.,
Beilock, Kulp, Holt, & Carr, 2004).
Is cognitive control therefore confined to relatively carefree moments in life? Perhaps a
more optimistic conclusion is possible. Both informal observations and theoretical considerations
suggest that cognitive control often proceeds remarkably well even under demanding conditions.
Indeed, people sometimes seem to rise to the occasion and mobilize greater levels of cognitive
control when demands are high. In line with these observations, contemporary theories of
intentional action suggest that people are able to better shield their intentions against unwitting loss
when they perceive or anticipate hindrances (Carver & Scheier, 2005; Gollwitzer, 1993; Kuhl,
1984). Applied to cognitive control tasks, this idea suggests that greater difficulties during cognitive
control may signal that the current level of control needs to be enhanced. Accordingly, greater
difficulties during cognitive control may trigger compensatory adjustments (cf. Miller, Galanter, &
Pribram, 1960). Because high demands render cognitive control more difficult (e.g., Lorist et al.,
2005), it stands to reason that high demands can also trigger compensatory increases in cognitive
control.
Demanding conditions may thus exert a complex influence on cognitive control. On some
occasions, high demands undermine cognitive control, whereas on other occasions, high demands
may lead people to mobilize their cognitive control capacities, resulting in increases in cognitive
When The Going Gets Tough… 70
control. One factor that influences the dynamic mobilization of control resources may be the
person’s disposition towards action versus state orientation (Kuhl, 1984, 1994a, 2000; Kuhl &
Beckmann, 1994a). Action orientation is conceived as a meta-static (change-promoting) regulatory
mode that is characterized by decisiveness and initiative. Action orientation thus facilitates
intentional action. By contrast, state orientation is conceived as a cata-static (change-preventing)
regulatory mode that is characterized by indecisiveness and hesitation. State orientation thus leads
to the perseveration of current mental and behavioral states. In short, action versus state orientation
indexes whether a person is able to achieve the mental and behavioral changes to terminate the
status quo (Kuhl, 1984; cf. Jostmann, Koole, Van der Wulp, & Fockenberg, 2005; Chapter 3; Koole
& Jostmann, 2004).
People may acquire a stable disposition towards action versus state orientation depending on
their socialization experiences (Kuhl, 1994a, 2000; Koole, Kuhl, Jostmann, & Finkenauer, 2006).
Particularly socialization conditions during childhood seem to be important predictors whether a
person becomes more action- versus state-oriented. Environments that encourage children to
motivate themselves when hindrances occur are likely to foster action orientation. By contrast,
environments that impair children’s ability to motivate themselves (i.e., overly controlling or
neglecting environments) are likely to foster state orientation. Through repeated learning
experiences, some individuals may come to react habitually in an action-oriented manner to high
demands, whereas other individuals come to habitually react to demands in a state-oriented manner.
Kuhl (1981, 1994b) developed a self-report scale that assesses individual differences in action
versus state orientation. Based on individuals' responses on this scale, they can be classified as
either predominantly action- or state-oriented.
Action- compared to state-oriented individuals may be better able to induce the mental and
behavioral changes to exert cognitive control under high demands. As outlined above, a particular
problem with cognitive control under high demands is that high demands can reduce the
When The Going Gets Tough… 71
effectiveness of working memory (cf. Braver & Cohen, 2000; Kane & Engle, 2003; Lorist et al.,
2005). An effective way to cope with the effects of high demands on cognitive control is therefore
to protect one’s working memory against high demands. Recent research (Jostmann & Koole, in
press; Chapter 2) found that action-oriented individuals make more efficient use of their working
memory capacity under high demands than state-oriented individuals as indicated by their
respective performance in an operation span (OSPAN) task (cf. Turner & Engle, 1989). In view of
the fundamental importance of working memory for cognitive control (Kane & Engle, 2003), these
findings suggest that action-oriented individuals may be better able to exert cognitive control under
high demands than state-oriented individuals.
At first sight, action versus state orientation might seem functionally equivalent to chronic
individual differences in high versus low working memory capacity (Feldman Barrett, Tugade, &
Engle, 2004). Specifically, past research has found individuals with high working memory capacity
to display greater cognitive control in Stroop tasks than individuals with low working memory
capacity (Kane & Engle, 2003; Long & Prat, 2002). However, unlike chronic individual differences
in working memory capacity, action versus state orientation refers to how efficiently individuals
can use their working memory capacity under demanding conditions. Action- compared to state-
oriented individuals update their working memory capacity more efficiently under high-demanding
conditions but not under low-demanding conditions (Jostmann & Koole, in press; Chapter 2).
Accordingly, functional differences between action-oriented and state-oriented individuals in
cognitive control emerge primarily under high-demanding conditions. The dynamic role of the
situational context thus distinguishes action versus state orientation from other well-studied
individual differences such as working memory capacity.
Action versus state orientation is also distinct from individual differences in the motivation
to mobilize great efforts (Kuhl, 1984). Specifically, some individuals may be generally more
motivated to mobilize their efforts during challenging tasks than other individuals (cf. Brehm &
When The Going Gets Tough… 72
Self, 1989). By contrast, action- versus state-orientated individuals do not systematically differ in
how much effort they are willing to invest. Instead, action- versus state-oriented individuals differ
in how efficiently they can use their processing capacities during challenging tasks (Jostmann &
Koole, in press; Chapter 2; cf. Eysenck & Calvo, 1992). In the context of cognitive control, effort
mobilization often invokes subsidiary costs under high demands due to a speed/accuracy trade-off
(i.e., faster responses at the cost of decreased accuracy or vice versa; see Boksem, 2006; cf.
Hockey, 1997). By contrast, because of action-oriented individuals’ greater processing efficiency
under high demands, greater cognitive control among action- compared to state-oriented individuals
is unlikely to involve a speed/accuracy trade-off.
Research on Action Orientation and Cognitive Control
Though largely indirect, empirical research supports the notion that action versus state
orientation moderates performance of complex tasks that presumably require some amount of
cognitive control. In one study, for instance, action-oriented students reported higher rates of goal
attainment in various life domains compared to their state-oriented fellow students (Diefendorff,
Lord, Hepburn, Quickle, Hall, & Sanders, 1998). Another study found higher correlations between
exercise intentions and behavior among action-oriented compared to among state-oriented
individuals (Kendzierski, 1990). Finally, action-oriented individuals were found to be better able
than state-oriented individuals to control the negative behavioral consequences of alcohol-
consumption (e.g., drunk driving; Palfai, McNally, & Roy, 2002), and to control their eating
behavior (Palfai, 2002).
The aforementioned studies did not measure or manipulate demands. However, additional
work suggests that enhanced cognitive control among action-oriented rather than state-oriented
individuals emerges especially under demanding conditions. First, performance pressure led semi-
professional basketball players to perform better when they were action-rather than state-oriented
(Heckhausen & Strang, 1988). The same investigation revealed reductions in physiological arousal
When The Going Gets Tough… 73
under performance pressure among action-oriented but not among state-oriented players. Second,
time pressure led action-oriented individuals to engage in a more parsimonious and less time-
consuming decision-making strategies compared to state-oriented individuals (Stiensmeier-Pelster,
1994). Finally, high demands left action-oriented participants more likely than state-oriented
participants to switch from an unattractive to a more attractive activity (Kuhl & Beckmann, 1994b),
and to change directions in a motor movement task (Dibbelt, 1997).
Initial indications suggest that functional differences between action- and state-oriented
individuals are due to a goal neglect mechanism. Recall that the ability to overcome goal neglect
requires a person to initiate cognitive control when the appropriate situational context is
encountered. In line with this, action- compared to state-oriented individuals procrastinate less
(Blunt & Pyschyl, 1998) and have fewer difficulties to initiate actions (Dibbelt, 1997; Kuhl &
Beckmann, 1994b). By contrast, action- compared to state-oriented individuals are not necessarily
better at maintaining a difficult task when task initiation is facilitated by external prompts
(Baumann & Kuhl, 2005; Dibbelt, 1997; Fuhrmann & Kuhl, 1998). Though preliminary, these
findings are consistent with a goal neglect account (cf. Jostmann & Koole, in press; Chapter 2).
The available evidence on action orientation and cognitive control, though suggestive,
suffers from important limitations. First, many of the aforementioned studies did not assess or
manipulate the level of demand. Therefore, in many cases, we can only speculate whether
performance differences between action- and state-oriented individuals were indeed due to high
demands, as our theoretical analysis would suggest. Second, the studies that did consider the role of
demand did not rely on established paradigms in assessing cognitive control. Third and last,
previously used paradigms did not directly examine goal neglect processes in cognitive control (cf.
Kane & Engle, 2003). We designed the present research to overcome these limitations.
When The Going Gets Tough… 74
The Present Research and Hypotheses
In the present research, we examined the role of action versus state orientation in moderating
the impact of high demands on cognitive control. Our general hypothesis was that a high-
demanding context would improve cognitive control among action-oriented compared to state-
oriented participants. In a low-demanding context, by contrast, we did not expect action-oriented
participants to display better cognitive control than state-oriented participants. Indeed, state-
oriented participants sometimes outperform action-oriented participants under low-demanding
conditions (e.g., Jostmann & Koole, in press; Chapter 2; cf. Koole, Kuhl, Jostmann, & Vohs, 2005).
Accordingly, we predicted that state-oriented participants under low-demanding conditions would
display higher or equal levels of cognitive control compared to action-oriented participants.
We conducted four studies that each used different operationalizations of high demands. In
Study 4.1, we induced a demanding context by having participants complete a working memory
task. In Study 4.2, we manipulated high versus low demand as a combination of task duration and
trial difficulty in a Stroop task. In Study 4.3, we examined self-reported levels of demand in
participants’ personal lives. In Study 4.4, we induced high versus low levels of demand by
manipulating the activation of an uncompleted intention. In Study 4.4, we also examined whether
the effects of action versus state orientation were, as hypothesized, mediated by goal neglect (Kane
& Engle, 2003). Across all four studies, we used a Stroop task to measure cognitive control.
In the Stroop task, variations in cognitive control can be manifested either in shifted
response time distributions or in changes in the number of erroneous responses. A slow response
latency on a given trial often reflects the increased difficulty to exert cognitive control. By contrast,
an error often indicates complete lapse of cognitive control on a given trial. One factor that
determines the locus of cognitive control variations is the proportion of congruent relative to
incongruent trials. When the task context includes more congruent than incongruent trials, failure to
exert cognitive control on one of the rare incongruent trials is more likely compared to when the
When The Going Gets Tough… 75
task context includes equal or even greater numbers of incongruent relative to congruent trials (for
an elaborate discussion on this point, see Kane & Engle, 2003). Studies 4.1 – 4.3 included equal
numbers of congruent and incongruent trials. We therefore expected effects on cognitive control to
emerge in response times rather than errors in Studies 4.1 – 4.3. By contrast, in Study 4.4, we
systematically varied the proportion of congruent and incongruent trials. Depending on whether
conditions included more congruent or more incongruent trials, we expected cognitive control
variations to emerge in either response times or errors.
Study 4.1
In Study 4.1, we sought to obtain initial evidence for our hypothesis that action-oriented
individuals display greater cognitive control in a demanding context than state-oriented individuals.
To induce a demanding context, we administered an OSPAN task, a widely investigated task that
draws on working memory (Turner & Engle, 1989). We reasoned that performing the OSPAN task
would put a strain on working memory and thereby induce a high-demanding context. Because
action-oriented participants are better able to cope with high demands, we expected them to display
greater cognitive control after the OSPAN task than state-oriented participants.
A second purpose of Study 4.1 was to test our assumption that the effects of action versus
state orientation occur over and above individual differences in working memory capacity.
Following past research (Engle, Tuholski, Laughlin, & Conway, 1999; Kane & Engle, 2003), we
assessed individual differences in working memory capacity by computing participants’ scores on
the OSPAN task. Past research has found that high-span individuals display less Stroop interference
than low-span individuals (Kane & Engle, 2003; Long & Prat, 2002). The robustness of this effect
was greater when less incongruent Stroop trials were included, presumably because high numbers
of incongruent trials reduce the attentional burden of working memory. Nevertheless, past research
still found significantly less Stroop interference among high- versus low-span individuals when the
rate of incongruent trials was as high as 80% (Kane & Engle, 2003, Experiment 4; cf. Long & Prat,
When The Going Gets Tough… 76
2002). Because the rate of incongruent trials in Study 4.1 of the present research was considerably
smaller (33%), we expected high-span individuals to display less Stroop interference than low-span
individuals.
To summarize, the OSPAN task in Study 4.1 served two functions. First, the task was used
to induce a demanding context. Second, the task allowed us to measure participants’ working
memory capacity. Recent work has shown that action orientation is only related to higher span
scores under high-demanding conditions (Jostmann & Koole, in press; Chapter 2). Because
participants in Study 4.1 performed the OSPAN task under low-demanding conditions, we expected
that action versus state orientation would not correlate with OSPAN. Moreover, because of the
conceptual separability between action versus state orientation and working memory capacity (cf.
Jostmann & Koole, in press; Chapter 2; Kuhl, 2000), we expected action- compared to state-
oriented individuals to display less Stroop interference even when we statistically controlled for
individuals’ span scores.
Method
Participants
Fifty-seven paid volunteers at the Vrije Universiteit Amsterdam (16 men and 41 women,
average age 20) participated in the experiment. One participant was excluded from the dataset
because he had responded to the mathematical equations during the OSPAN task in less than a
second per equation (Grand M = 8 s), and had solved less than 50% of the equations correctly
(Grand M = 87%). Three additional participants were excluded because they failed a test for
colorblindness. The main dependent variables consisted of participants’ response latencies and
errors during the Stroop task.
Procedure
Upon arrival in the laboratory, participants were led into individual cubicles, each
containing a computer. The experimenter explained that all instructions would be administered via a
When The Going Gets Tough… 77
computer program and left. Participants were first informed that they would participate in several
unrelated studies that were allegedly administered together for efficiency reasons. Participants then
began with the first study, which was introduced as a study on personality and contained our
assessment of individual differences in action versus state orientation.4.2 Next, participants moved
on with the OSPAN task, which served as an induction of demand and assessed individual
differences in working memory capacity. Following the OSPAN task, participants completed a
Stroop task, which measured cognitive control. Participants were subsequently tested for
colorblindness by having them to detect numbers among patterns of colored dots. Finally,
participants were debriefed, paid, and thanked by the experimenter.
Independent Variables
Action versus State Orientation. We assessed individual differences in action versus state
orientation by a Dutch translation of the demand-related subscale (AOD) of the Action Control
Scale (ACS-90; Kuhl, 1994b).4.3 The ACS-90 has been validated in over 60 published studies (for
reviews, see Diefendorff, Hall, Lord, & Strean, 2000; Koole & Kuhl, in press; Kuhl & Beckmann,
1994a). These studies have been conducted across a wide range of domains such as physiological
arousal, intention memory, work psychology, therapeutic outcomes, athletic performance, and
medicine intake. Notably, the effects of action versus state orientation are independent of self-
efficacy beliefs (Diefendorff, 2004) and achievement motivation (Heckhausen & Strang, 1988; cf.
Footnote 4.2), and occur over and above the effects of the Big Five personality dimensions
(Diefendorff et al., 2000).
The AOD scale consists of 12 items that were intermingled and presented in a different
random order for each participant. Each item describes a demanding situation and an action-
oriented versus state-oriented way of coping with that situation. For each item, participants are
asked to select the response that best describes their own reaction to that situation. An example item
is “When I have to take care of something important but which is also unpleasant: (a) I do it and get
When The Going Gets Tough… 78
it over with, or (b) It can take a while before I can bring myself to do it”. Option a reflects the
action-oriented and option b reflects the state-oriented response alternative. Action-oriented
responses were coded as 1, and state-oriented responses were coded as 0 and summed for the entire
scale. Scores could range from 0 – 12. Participants who gave seven or more action-oriented choices,
were assigned to the action-oriented group (n = 36); participants who gave six or fewer action-
oriented responses, were assigned to the state-oriented group (n = 17).4.4 Reliability for the AOD
scale was sufficient, Kuder-Richardson (KR) 20 coefficient = .67.
Operation Span. The OSPAN task was adapted from Schmader and Johns (2003; cf. Turner
& Engle, 1989). In the task, participants were requested to memorize short series of words and
simultaneously evaluate simple mathematical equations. Specifically, participants were to indicate
by a key-press whether an equation was correct or incorrect [e.g., “Is (4 x 8) – 11 = 21?”]. When the
equation was correct, participants had to press the A-button on the left side of the keyboard. When
the equation was incorrect, participants had to press the 6-button on the numeric pad on the right
side of the keyboard. After each equation, a word was presented that had to be memorized. After a
series of equation word pairs (i.e., a set), participants were requested to type in all words they
recalled from the preceding set. After this, a new set of equation word pairs started. All participants
were informed that they would receive feedback about their performance at the end of the task.
Sets differed in length from three to five equation-word pairs per set. Five sets of each
length were presented, allowing scores to range from 0 to 60. Presentation order of the sets was
randomized for each participant, such that the number of words to recall was unknown until recall.
The generation of mathematical equations followed the criteria of Schmader and Johns (2003). Half
of the equations were correct whereas the remaining equations were incorrect. The 60 words used in
the test were monosyllabic Dutch nouns that were randomly assigned to sets. Within sets, equation
word pairs were presented in a different random order for each participant. The assignment of
equations and words to sets was identical for all participants.
When The Going Gets Tough… 79
Each trial within a set began with the appearance of a fixation asterisk on the screen for 1 s
followed by an equation, which remained visible until participants had pressed a response key.
After this, the screen remained blank for 500 ms, followed by the appearance of a word to be
recalled. After 2 s, the screen went blank again for 1 s, followed by the next trial. Sets were
separated by the announcement “next set”, which remained visible for 3 s. The recall phase at the
end of each set lasted until participants pressed a response key. Thus, the presentation of the
equations and the recall phase were participant-paced, whereas the presentation of the words to
remember was computer-paced. The computer unobtrusively recorded the words recalled,
participants’ responses on the equations, the time spent on each equation, and the time spent during
each recall phase.
To assess individual differences in working memory capacity, we added the number of
correctly remembered words for each participant. Subsequently, we divided the sample at the
midpoint (i.e., 56 words). Accordingly, participants who had remembered 56 or less words correctly
(n = 28) were classified as individuals with low working memory capacity, whereas participants
with more than 56 correctly remembered words (n = 25) were classified as individuals with high
working memory capacity. Given the small sample size in the present research we decided not to
exclude participants from the two mid-quartiles of our sample or participants who had incorrectly
evaluated less than 85% of the equations, as past research has done (Kane & Engle, 2003).
Rerunning the analyses without participants who had evaluated less than 85% of the equations
correctly (n = 15) did not substantially change the results.
Stroop Task
During the Stroop task, participants were asked to respond to colored letter-strings. If a
letter-string on the screen was presented in blue ink, participants were to press the 6-key on the
numeric pad of the keyboard. If the word was presented in red ink, participants were to press the A-
key on the keyboard. Some letter-strings were color words (RED or BLUE), whereas others
When The Going Gets Tough… 80
consisted of a series of Xs. Stimuli were either displayed in red or blue. Participants were instructed
to ignore the meaning of the words and to focus on the ink colors only. In addition, they were
encouraged to respond quickly while being accurate. To promote quick responding, participants
were asked to place their fingers on the response keys throughout the task. We further encouraged
participants to focus on the presentation location of all stimuli on the center of the screen during the
entire task. Before the actual task, participants completed 10 practice trials. After each practice trial,
the computer provided feedback regarding the accuracy of participants’ responses. Subsequently,
the participants proceeded with the actual task, which consisted of 60 experimental trials. No
feedback was provided during the actual task.
Trials were presented successively and in a different random order for each participant. The
actual task included 20 congruent trials (i.e., RED in red, or BLUE in blue), 20 neutral trials (i.e.,
XXXX in red or blue), and 20 incongruent trials (i.e., RED in blue, or BLUE in red). Each trial
started with the presentation of a fixation asterisk for 1 s, immediately followed by the presentation
of a colored letter string. After participants had given a response, the screen remained blank for 2 s,
until the fixation asterisk reappeared to indicate the onset of the next trial. For each trial, the
computer unobtrusively recorded participants’ response latency and response key. The fixation
asterisk and the target color words were presented in the center of a white computer screen (font
type Arial, size 36, resolution 1024 x 768, on 17˚ CRT Iiyama monitors). During the entire task, the
word “red” in black ink and the response key “A” were displayed in the lower left part of the
screen, and the word “blue” in black ink and the response key “6” were displayed in the lower right
part.

Results
Color Evaluation Latencies. Before analyzing the response latency data, we removed
erroneous responses (3.5% of all responses) and responses faster than 300 ms (1.5% of all
responses) from the dataset. All analyses in Studies 4.1 – 4.4 were performed on log-transformed
latencies. To facilitate interpretation of the results, we report untransformed means in ms
throughout the article.
On average, participants’ responses on neutral trials were faster than responses on
incongruent trials, F(1, 52) = 57.20, p < .001, ηp2 = .52 (M = 512 vs. M = 597). An additional
analysis revealed that average responses on congruent trials were as fast as responses on neutral
trials, F < 1 (M = 516 vs. M = 512). Thus, color evaluation latencies in the Stroop task revealed
evidence for interference, but not facilitation. Throughout the present investigation, some of the
studies revealed Stroop facilitation whereas others did not. This inconsistent pattern may be due to
the use of Xs as neutral stimuli (cf. MacLeod, 1991). To the extent that we did find Stroop
When The Going Gets Tough… 82
facilitation in the present investigation, it was not moderated by action versus state orientation, all
Fs < 1. We therefore do not report analyses of Stroop facilitation in the present research.
We proceeded by subtracting average response latencies for neutral trials from average
response latencies for incongruent trials. The resulting difference score can be interpreted as an
index of Stroop interference with higher scores indicating more Stroop interference (cf. MacLeod,
1991). (Subtracting response latencies on congruent trials from response latencies on incongruent
trials as an alternative index for Stroop interference revealed equivalent results across Studies 4.1 –
4.4.) A one-way ANOVA on Stroop interference revealed the predicted effect of orientation, F(1,
51) = 4.49, p < .04, ηp2 = .08. Relevant means are displayed in Table 4.1a. As expected, action-
oriented participants displayed smaller Stroop interference than state-oriented participants (M = 68
vs. M = 121).
Errors. We subtracted the number of errors on neutral trials from errors on incongruent trials
to obtain an index of Stroop interference in errors. A one-way ANOVA on Stroop interference in
errors revealed no effect of orientation, all Fs < 1. Further analyses revealed that the effect of
orientation on Stroop interference in response latencies remained intact when we statistically
controlled for Stroop interference in errors. Thus, the effect of orientation was not due to a
speed/accuracy trade-off.
Supplementary Analyses. We further tested the effect of working memory capacity on
Stroop interference. As expected, high-span participants displayed less Stroop interference in
response latencies than low-span participants (M = 59 vs. M = 108); F(1, 50) = 4.56, p < .04, ηp2 =
.08. Relevant means are displayed in Table 1b. Notably, this analysis included participants’
responses on the AOD scale as a covariate, which did not remove the effect of working memory
capacity on Stroop interference. Rerunning this analysis without two participants whose span scores
were more than 2.5 SD below the group mean (Grand M = 55.72; SD = 3.61) left the results intact,
indicating that OSPAN effects on Stroop interference were not due to the influence of outliers.
When The Going Gets Tough… 83
Action orientation and OSPAN performance thus both predicted Stroop interference. To
examine whether the effect of action versus state orientation on Stroop interference in response
latencies was independent from chronic individual differences in working memory capacity, we
reran the analysis with participants’ span scores as a covariate. As expected, including span scores
as a covariate left the effect of orientation intact, F(1, 50) = 5.50, p < .03, ηp2 = .10. Moreover,
participants’ AOD scores and their span scores (both entered as continuous variables) were
uncorrelated, r = -.14, ns.
Additional analyses revealed that participants on average studied the arithmetic equations
during the OSPAN task for 8 s before they pressed a response key. Moreover, participants needed
on average 11.7 s to type in the words during the recall phase of each set. Equation presentation
time was uncorrelated with span scores (r = -.10, ns), whereas recall time was negatively correlated
with span scores (r = -.36, p < .02). The effects on Stroop interference in response latencies for
action- versus state-oriented individuals and high- versus low-span individuals, remained intact
when we controlled for equation presentation time, recall time, and the number of correctly solved
equations (Grand M = 87%), respectively.

Discussion
In Study 4.1, we found initial evidence for our hypothesis that action versus state orientation
moderates cognitive control under high demands. After performing a demanding task (i.e.,
OSPAN), action-oriented participants displayed less Stroop interference in response latencies than
state-oriented participants. Importantly, reduced Stroop interference in response latencies did not
come at the expense of greater Stroop interference in errors. The effect of action orientation was
thus not due to a speed/accuracy trade-off. This pattern of findings is theoretically meaningful,
because speed/accuracy tradeoffs occur when individuals simply increase their efforts to enhance
task performance under high demands (Boksem, 2006). The results of Study 4.1 thus indicate that
demand-induced increases in cognitive control among action-oriented individuals results from
increased efficiency rather than increased efforts.
Study 4.1 further replicated past research (Kane & Engle, 2003; Long & Prat, 2002) by
demonstrating that participants with high working memory capacity displayed greater cognitive
control than participants with low working memory capacity. Importantly, the effect of action
versus state orientation on cognitive control remained intact when we controlled for individual
differences in working memory capacity. Indeed, Study 4.1 yielded no correlation between action
versus state orientation and individual differences in working memory capacity. In sum, Study 4.1
revealed that action versus state orientation contributes to cognitive control above and beyond
individual differences in working memory capacity (cf. Jostmann & Koole, in press; Chapter 2).
Compared to previous research (Kane & Engle, 2003), participants in Study 4.1 generally
obtained relatively high OSPAN scores. Possibly, our OSPAN task was somewhat easier to perform
than comparable tasks during previous research (but see Schmader & Johns, 2003). Because our
version of the OSPAN task was in part participant-paced, one might wonder whether participants
had used idiosyncratic strategies (e.g., extending the equation presentation time) to reduce the
working memory load of the task (cf. Friedman & Miyake, 2004). However, we think that at least
When The Going Gets Tough… 85
two arguments speak against undue influence of idiosyncratic strategies in the present investigation.
First, as in previous research (Kane & Engle, 2003; Long & Prat, 2002), span scores in Study 4.1
predicted cognitive control in the Stroop task. Close inspection of the data revealed that this relation
did not depend on outliers with extremely low span scores. Second, correlational analyses revealed
that increased processing time during equation presentation and during word recall was unrelated to
greater span scores. Indeed, controlling for equation presentation time and word recall time had no
effects on the relation between OSPAN and Stroop interference. In brief, there is no indication for
undue influence of idiosyncratic strategies in our OSPAN task.
Study 4.2
In Study 4.2, we examined the effects of action versus state orientation under high- versus
low-demanding conditions. To induce varying levels of demand, we changed some parameters of
the Stroop task itself. Performing the Stroop task strains working memory (Kane & Engle, 2003),
which, after prolonged task duration, depletes processing resources and thus renders the task more
demanding (cf. Lorist et al., 2005). Accordingly, performance on trials that occur later during the
Stroop task should be more demanding than performance on trials that occur early during the task.
Based on this assumption, we predicted that action versus state orientation moderates cognitive
control in the Stroop task after prolonged task duration such that action-oriented participants display
greater cognitive control on later trials than state-oriented participants. We predicted no greater
cognitive control among action- compared to state-oriented participants after short task duration
because demands are relatively low during early trials.
Prolonged engagement in the Stroop task not only strains working memory but also
increases task practice. Task practice, in turn, reduces Stroop interference (cf. Roe, Wilsoncroft, &
Griffiths, 1980). To control for potential practice effects, we manipulated the difficulty of Stroop
trials. Half of the trials were regular Stroop trials consisting of colored strings such as those used in
Study 4.1 (hereafter, “regular trials”). The remaining trials (hereafter, “difficult trials”) included a
When The Going Gets Tough… 86
second task in addition to the Stroop task. This second task required participants to evaluate two
consecutively presented letters. Participants thus had to divide their attention over the Stroop task
and the anticipation of the letter task during difficult trials. We reasoned that difficult trials would
impose an extra load on working memory as they require dual task coordination including the
monitoring and sequencing of behavioral subgoals (cf. Kazén & Kuhl, 2005; Lavie, Hirst, de
Fockert, & Viding, 2004). Because complex tasks should require more practice than simple tasks,
we reasoned that practice effects would occur on regular trials but not (or at least significantly less)
on difficult trials.
In line with our general hypothesis, we predicted that action versus state orientation would
moderate cognitive control after prolonged task duration on difficult trials but not on regular trials.
Specifically, action-oriented individuals were expected to display less Stroop interference than
state-oriented individuals during difficult trials that occur later during the task.
Method
Participants and Design
Participants were 40 paid volunteers at the Vrije Universiteit Amsterdam (16 men and 24
women, average age 21). The experimental design was 2 (orientation: action vs. state; between
participants) x 2 (trial difficulty: difficult vs. regular, within participants) x 3 (task duration: low vs.
intermediate vs. high; within participants). Two participants failed the colorblindness test and were
therefore removed from the dataset. The main dependent variables consisted of participants’
average response latencies and errors in a Stroop task.
Procedure
Participants started by filling out some questionnaires, which contained our assessment of
individual differences in action versus state orientation (KR 20 = .64). Based on their responses,
sixteen participants were classified as state-oriented, whereas twenty-two participants were
classified as action-oriented. We subsequently administered the Stroop task, which consisted of
When The Going Gets Tough… 87
three consecutive blocks of trials. The Stroop task served as our measure of cognitive control, and
also included our manipulations of trial difficulty and task duration. After the Stroop task, we
administered a test for colorblindness. Finally, participants were paid, debriefed, and thanked for
their participation.
Stroop task
Instructions for the Stroop task were identical to those in Study 4.1 with the following
exceptions: Participants were informed that some ink color evaluations, which were referred to as
“Task 1”, would be followed by a second task (“Task 2”). During Task 2, participants had to decide
whether a consecutively presented pair of letters was of the same type or of a different type. When
the letters were of the same type (i.e., either both letters are vowels, or both letters are consonants),
participants were to press the A-key on the keyboard. When the letters were of a different type (i.e.,
one letter is a vowel, and the other letter is a consonant), participants were to press the 6-key of the
numeric pad of the keyboard. At the beginning of each trial, participants were informed whether the
trial consisted only of Task 1, or of Task 1 and Task 2.
The onset of each trial was indicated by the word “next”, which remained visible for 1 s. It
was immediately followed for 1 s by a prompt that informed participants whether the trial consisted
only of “Task 1”, or “Task 1 + Task 2”. Next, participants saw a fixation asterisk for 1 s, followed
by a blank screen for 1 s. Then, a colored letter string appeared and remained on the screen until
participants pressed a response key. When the trial included only Task 1, the screen subsequently
remained blank for 1 s until the word “next” reappeared on screen indicating the onset of the next
trial. However, when the trial also included Task 2, participants’ responses to the colored letter
strings were followed by a blank screen for 1 s. Next, a letter appeared for 50 ms on the screen,
after which it was replaced by a second letter. The second letter remained on the screen until
participants had given a response. Subsequently, the screen remained blank for 1 s, followed by the
word “next” to indicate the onset of the next trial.
When The Going Gets Tough… 88
Before starting with the actual task, participants completed a block of 10 practice trials
during which feedback was provided on response correctness. No feedback was given during the
actual task. The actual task consisted of 180 trials divided over three blocks of 60 trials. Task
duration was operationalized as the position of the three blocks. Accordingly, task duration was
lowest during the first block, intermediate during the second block, and highest during the third
block. Between every two blocks, a short break (30 s) was included. In each block, all color words
(congruent, neutral, incongruent) and ink colors (blue and red) were equally represented. During
half of the trials of each block, Task 1 was followed by Task 2. During Task 2, half of the letter
pairs were of the same type, whereas the remaining pairs were of a different type. The order in
which the three blocks were presented was identical for each participant. The presentation of the 60
trials within each block varied randomly between participants.
Results
Stroop Effect
Color Evaluation Latencies. Before analyzing response latencies, we removed erroneous
responses (4% of all responses) and responses faster than 300 ms (1.2% of all responses) from the
dataset. On average, responses on neutral trials were faster than responses on incongruent trials,
F(1, 37) = 60.88, p < .001, ηp2 = .62 (M = 642 vs. M = 733). Average responses on congruent trials
were as fast as responses on neutral trials, F < 1 (M = 639 vs. M = 642). Thus, there was
interference but no facilitation. To examine whether our manipulation of trial difficulty was
successful, we conducted a 2 (trial difficulty) x 3 (task duration) x 3 (trial type) repeated measures
analysis on Stroop interference. As indicated by a significant main effect of trial difficulty,
participants’ responses on regular trials were in general faster than participants’ responses on
difficult trials (M = 661 vs. M = 680), suggesting that trials involving secondary task preparation
were generally more difficult than trials that did not require secondary task preparation, F(1, 37) =
20.86, p < .001, ηp2 = .36.

We proceeded by subtracting participants’ mean response latencies on neutral trials from
participants’ mean response latencies on incongruent trials to obtain an index for Stroop
interference. A 2 (orientation) x 2 (trial difficulty) x 3 (task duration) ANOVA on Stroop
interference with repeated measures on the last two factors yielded a significant two-way interaction
between trial difficulty and task duration, F(2, 72) = 5.75, p < .006, ηp2 = .14. A closer examination
of this two-way interaction revealed a practice effect that was moderated by trial difficulty. As
predicted, Stroop interference on regular trials decreased as a function of task duration, F(2, 74) =
6.84, p < .003, ηp2 = .16, with greater Stroop interference in the first block (M = 140) compared to
the second block (M = 91) and the third block (M = 40). By contrast, there was no practice effect for
difficult trials, F < 1. Specifically, Stroop interference was similar in the first block (M = 107), the
second block (M = 80), and the third block (M = 101). Thus, as predicted, increased task difficulty
interfered with task practice effects.
The analysis also revealed the predicted three-way interaction effect, F(2, 72) = 5.22, p <
.009, ηp2 = .13. All relevant means are displayed in Table 4.2 (except for the means of the second
block, which were not affected by orientation and therefore, for the sake of brevity, not included in
the table). To facilitate interpretation of the three-way interaction, we analyzed the effects
separately for each block. Recall that the position of the blocks served as our operationalization of
task duration with the first block being less demanding than the second block, and the second block
being less demanding than the third block.
Block 1. A 2 (orientation) x 2 (trial difficulty) ANOVA yielded a significant main effect of
trial difficulty. Stroop interference was higher on regular trials than on difficult trials, F(1, 36) =
4.23, p < .05, ηp2 = .11 (M = 140 vs. M = 107). This main effect of trial difficulty was qualified by a
significant two-way interaction of orientation and trial difficulty, F(1, 36) = 6.00, p < .02, ηp2 = .14.
We conducted follow-up analyses to determine the locus of this unexpected effect. Action-oriented
participants displayed less Stroop interference on regular trials than state-oriented individuals, an
When The Going Gets Tough… 91
effect that was only marginally significant, F(1, 36) = 3.06, p = .09, ηp2 = .08 (M = 94 vs. M = 202).
By contrast, action- versus state-oriented participants displayed similar Stroop interference on
difficult trials, F < 1 (M = 110 vs. M = 101). Another way to interpret the results is to state that
state-oriented participants displayed more Stroop interference on regular trials than on difficult
trials, F(1, 15) = 6.97, p < .02, ηp2 = .32. By contrast, Stroop interference among action-oriented
individuals did not differ as a function of trial difficulty, F < 1.
Block 2. A 2 (orientation) x 2 (trial difficulty) ANOVA yielded no significant effects, all Fs
< 1. Specifically, action-oriented and state-oriented participants displayed similar Stroop
interference on difficult trials (M = 79 vs. M = 81) and on regular trials (M = 80 vs. M = 105).
Block 3. A 2 (orientation) x 2 (trial difficulty) ANOVA revealed a significant main effect of
trial difficulty, F(1, 36) = 7.82, p < .009, ηp2 = .18. Specifically, Stroop interference was higher on
difficult trials than on regular trials (M = 101 vs. M = 40). Furthermore, we found a non-significant
main effect of orientation, F(1, 36) = 2.07, p = .16, ηp2 = .05. More importantly, however, the
analysis revealed the expected two-way interaction between orientation and trial difficulty, F(1, 36)
= 5.56, p < .03, ηp2 = .13. Specifically, action-oriented and state-oriented participants displayed
similar Stroop interference on regular trials, F < 1 (M = 37 vs. M = 44). By contrast, action-oriented
individuals displayed lower Stroop interference than state-oriented individuals on difficult trials,
F(1, 36) = 6.15, p < .02, ηp2 = .15 (M = 58 vs. M = 159). Another way to interpret the two-way
interaction is to say that action-oriented participants showed similar Stroop interference on regular
and difficult trials, F < 1. By contrast, state-oriented individuals displayed more Stroop interference
on difficult trials than on regular trials, F(1, 15) = 9.19, p < .009, ηp2 = .38.
Errors. A 2 (orientation) x 2 (trial difficulty) x 3 (task duration) ANOVA on Stroop
interference in errors revealed no significant effects, all Fs < 1.6. Furthermore, there was no
indication for a speed/accuracy trade-off because the effects on Stroop interference in response
latencies remained intact when we controlled for Stroop interference in errors.
When The Going Gets Tough… 92
Letter task. Action-oriented participants’ error rates in the letter task were somewhat smaller
than state-oriented participants’ error rates in the letter task (M = 7% vs. M = 10%), F(1, 36) = 1.47,
p = .24, ηp2 = .04. Importantly, the effects on Stroop interference in response latencies remained
unchanged when we controlled for participants’ error rates in the letter task (Grand M = 8%).
Discussion
In Study 4.2, we varied level of demand by increasing the duration of the task and
manipulating task difficulty within the Stroop task. As expected, action- compared to state-oriented
participants displayed less Stroop interference on trials in the last of three consecutive blocks of
trials but not in the first or second block. Moreover, in line with our predictions, this effect emerged
on difficult trials (i.e., ink color evaluation followed by a letter evaluation) but not on regular trials
(i.e., solely ink color evaluation). Task practice in the third block likely decreased demands on
regular trials to an extent that action versus state orientation became irrelevant to efficiently
perform the regular Stroop trials. Notably, action- compared to state-oriented participants did not
generally perform better at difficult trials. The performance advantage of action-oriented
individuals only emerged after prolonged task duration made the task more demanding. Taken
together, Study 4.2 shows that the effects of action versus state orientation on cognitive control are
strongly moderated by the level of demand of the task context.
Stroop interference in Study 4.2 was not generally greater in the third block compared to the
first block. In fact, Stroop interference on regular trials declined as task duration proceeded,
whereas Stroop interference on difficult trials did not change. At first glance, this finding may seem
to contradict our assumption that sustained task engagement makes cognitive control tasks more
demanding. This apparent inconsistency can be resolved, however, if one considers that overt
cognitive control decrements across all participants are unlikely to occur within the comparatively
short task duration of Study 2 (which on average lasted 21 minutes). Indeed, Lorist and colleagues
(2005), for instance, report overt cognitive control decrements not until 30 minutes of continuous
When The Going Gets Tough… 93
task duration. To our knowledge, previous research did not consider the role of task difficulty,
which may have caused task practice to defer the occurrence of overt cognitive control decrements
during previous research. The present findings suggest, however, that task difficulty and action
versus state orientation are important factors to consider because they can moderate cognitive
control even at relatively short task durations.
Unexpectedly, participants’ performance in the first block revealed an interaction between
action versus state orientation and task difficulty. A closer examination revealed that the effects in
the first block were driven by decreased cognitive control among state-oriented participants on
regular compared to difficult trials. In the first block, task demands were still at a relatively low
level given that task duration had not yet progressed. Accordingly, state-oriented participants
showed no performance decrements on difficult trials. However, better performance on difficult
trials might have come at the cost of performance on regular trials. This would have been the case,
for instance, if state-oriented participants in the first block had formed a strong intention to perform
well on the following difficult trial. This intention may have undermined performance on the
intervening regular trials (cf. Kuhl & Helle, 1986; Shah et al., 2003). Although this explanation is
plausible, we did not explicitly predict the observed pattern in the first block. Future research is
therefore required to test the effects of shifting task priorities among action- versus state-oriented
individuals.
Study 4.3
In everyday life, people frequently encounter contexts that are more or less demanding.
During these real-life demands, people may have to plan and coordinate the pursuit of multiple
difficult and potentially incompatible goals. To the extent that such deliberations strain working
memory (Norman & Shallice, 1986), prolonged deliberation might lead to the depletion of
processing resources and less efficient use of working memory capacity (cf. Klein & Boals, 2001).
Because working memory is involved in cognitive control (Kane & Engle, 2003), real-life demands
When The Going Gets Tough… 94
may cause cognitive control decrements in much the same way as experimentally manipulated
demands. We designed Study 4.3 to examine this prediction.
Study 4.3 measured participants’ current level of demand in their personal lives. On the
basis of our theoretical analysis, we reasoned that the effects of real-life demands on cognitive
control would be moderated by action versus state orientation (cf. Baumann, Kaschel, & Kuhl,
2005). Among participants whose lives were currently demanding, we expected less cognitive
control in a Stroop task when participants were state-oriented as compared to when they were
action-oriented. By contrast, among participants whose lives were low-demanding, state-oriented
individuals should display similar or even greater cognitive control than action-oriented individuals
(cf. Jostmann & Koole, in press; Chapter 2; Koole et al., 2005).
Method
Participants and Design. Seventy-eight paid volunteers at the Vrije Universiteit Amsterdam
(29 men and 49 women; average age 20) participated in the experiment. The experimental design
was a 2 (orientation: action vs. state; between participants) x 2 (real-life demands: high vs. low;
between participants). Two participants failed a test for colorblindness and were therefore excluded
from the dataset. The main dependent variable consisted of participants’ average response latencies
and errors during the Stroop task.
Procedure. The equipment and general procedure were similar to Study 4.1. Participants
first answered a few questionnaires, including the ACS-90 (Kuhl, 1994b), to assess individual
differences in action versus state orientation (KR 20 = .64). Based on their responses, thirty-five
participants were assigned to the state-oriented group, whereas forty-one participants were assigned
to the action-oriented group. Participants then moved on with a Stroop task, which served as our
measure of cognitive control. Next, we assessed to what extent participants experienced their
current personal life as demanding. Finally, participants were tested for colorblindness, debriefed,
paid, and thanked by the experimenter.
When The Going Gets Tough… 95
Real-Life Demands. To assess real-life demands we asked participants to indicate to what
extent the following seven statements applied to them (1 = not at all; 7 = very much): Currently, I
am more busy than I usually am; Currently, I have particularly much to think of; I feel currently
under demand; I feel currently stressed out; I have a lot of work to do during the next days; I wish
my current life situation was more at ease; I find that others currently demand a lot from me.
Participants’ responses were averaged to obtain a single index of real-life demands (Cronbach’s
Alpha = .86). Participants who scored on average 4 or lower were assigned to the low demand
group (n = 37), whereas participants who scored on average higher than 4 were assigned to the high
demand group (n = 39).
Stroop task. The Stroop task in Study 4.3 was identical to the one in Study 4.1 with one
exception. We increased the number of trials such that there were 30 congruent trials (i.e., RED in
red, or BLUE in blue), 30 neutral trials (i.e., XXXX in red or blue), and 30 incongruent trials (i.e.,
RED in blue, or BLUE in red).
Results
Color Evaluation Latencies. Before analyzing response latencies, we removed erroneous
responses (3.0% of all responses) and responses faster than 300 ms (1.9% of all responses) from the
dataset. Initial analyses revealed that participants’ responses were quicker on neutral trials than on
incongruent trials, F(1, 75) = 46.43, p < .001, ηp2 = .38 (M = 524 vs. M = 581). Furthermore,
participants’ responses on congruent trials were as quick as responses on neutral trials, F < 1 (M =
524 vs. M = 524). We thus found interference but no facilitation.
We proceeded by subtracting average response latencies for neutral trials from average
response latencies for inconsistent trials to obtain an index of Stroop interference. A 2 (orientation)
x 2 (demand) ANOVA on Stroop interference revealed a significant interaction effect between
orientation and demands, F(1, 72) = 10.69, p < .003, ηp2 = .13. Relevant means are displayed in
Table 4.3. Among participants with high-demanding lives, those with an action orientation
When The Going Gets Tough… 96
displayed smaller Stroop interference effects than those with a state orientation, F(1, 72) = 4.06, p <
.05, ηp2 = .05 (M = 31 vs. M = 77). This pattern was reversed among participants with low-
demanding lives, such that those with an action orientation displayed higher Stroop interference
than those with a state orientation, F(1, 72) = 6.77, p < .02, ηp2 = .09 (M = 85 vs. M = 35).

Another way to interpret the two-way interaction is to note that, among action-oriented
participants, those with high levels of demand displayed less Stroop interference than those with
low levels of demand, F(1, 72) = 10.35, p < .003, ηp2 = .13. By contrast, among state-oriented
participants, those with high levels of demand displayed non-significantly more Stroop interference
that those with low levels of demand, F(1, 72) = 2.19, p = .15, ηp2 = .03.
Errors. A 2 (orientation) x 2 (demand) ANOVA on Stroop interference in errors revealed a
significant main effect of demand, F(1, 72) = 4.34, p < .05, ηp2 = .06. Participants with low-
When The Going Gets Tough… 97
demanding lives displayed higher Stroop interference in errors than participants with demanding
lives (M = 1.03 vs. M = .36). There was no main effect of orientation, F(1, 72) = 2.27, p = .14, ηp2 =
.03, and no interaction effect, F < 1. Given that the main effect of demand was not anticipated, we
conducted a (orientation) x (demand) ANOVA on Stroop interference in response latencies with
Stroop interference in errors as a covariate, which left the results intact. Furthermore, Stroop
interference in response latencies and Stroop interference in errors were uncorrelated (r = .06, ns).
Thus, lower Stroop interference in response latencies was not due to a speed/accuracy trade-off.
Discussion
As predicted, participants who reported having demanding lives displayed greater cognitive
control when they were action- rather than state-oriented. The results of Study 4.3 thus provide a
conceptual replication of Study 4.2 using real-life demands rather than task duration to
operationalize demands. By contrast, participants who reported having low-demanding lives
displayed greater cognitive control when they were state- rather than action-oriented. The latter
finding fits with the assumption that, under low-demanding conditions, state-oriented individuals
can function equally or even more effectively than action-oriented individuals (Jostmann & Koole,
in press; Chapter 2; see also Koole et al., 2005). An additional finding of Study 4.3 was that action-
oriented participants displayed greater cognitive control when demands were high rather than low.
This finding indicates that action-oriented individuals’ performance may actually benefit from
increased levels of demand.
Study 4.4
Why would high demands induce enhanced cognitive control among action-rather than
state-oriented individuals? In Study 4.4, we examined whether this pattern might be attributed to a
goal neglect mechanism. To overcome goal neglect, a person has to correctly remember the
intention that has to be executed and, importantly, initiate cognitive control in the appropriate
context. By contrast, the ability to overcome goal neglect is irrelevant if a person merely has to
When The Going Gets Tough… 98
maintain cognitive control. Once cognitive control is successfully initiated, executive systems
remain in a high-control state (Botvinick et al., 2001), which facilitates subsequent efforts to exert
cognitive control. Taken together, a goal neglect account predicts that action versus state orientation
moderates the impact of demands on cognitive control when cognitive control has to be initiated but
not when cognitive control merely has to be maintained.
Study 4.4 examined goal neglect processes by manipulating the availability of prompts (e.g.
De Jong et al., 1999; Dibbelt, 1997; Kane & Engle, 2003). When prompts are available, the
initiation of cognitive control no longer relies on the internal activation of the task intention.
Accordingly, prompts make cognitive control less dependent on goal neglect. By contrast, when no
prompts are available to initiate cognitive control, it is necessary to keep the task intention
continuously accessible in working memory. Accordingly, the absence of prompts makes cognitive
control more susceptible to goal neglect. Past research on Stroop interference has varied the
composition of Stroop trials to manipulate the availability of prompts (Kane & Engle, 2003). To
connect our findings to this work, we decided to manipulate prompts in a similar way.
In a Stroop task that was adapted from Kane and Engle (2003), we embedded critical trials
in a context of filler trials. Filler trials were either congruent (75% congruent condition) or
incongruent (12,5% congruent condition). Following Kane and Engle, we reasoned that a context of
congruent filler trials encourages participants to disregard the task instruction to ignore the word
meaning. Accordingly, every time participants encountered one of the rare incongruent trials in the
context of mainly congruent trials they had to re-initiate cognitive control. The context of congruent
trials thus made cognitive control highly sensitive to goal neglect. By contrast, a context of
incongruent filler trials continuously prompts the task intention to ignore the word meaning.
Accordingly, participants in the 12,5% congruent condition only needed to maintain cognitive
control. A context of incongruent filler trials thus made cognitive control less sensitive to goal
neglect. Theoretically, we regard goal neglect as a key mechanism that explains the functional
When The Going Gets Tough… 99
differences between action- and state-oriented individuals. Therefore, we expected high demands to
evoke performance differences between action- and state-oriented participants in the 75% congruent
condition but not necessarily in the 12,5% congruent condition.
The mechanism that underlies cognitive control has important implications for whether the
effects of action versus state orientation and high demands should be expected on response latencies
versus errors. As noted in the Introduction, cognitive control deficits on incongruent trials in a
context of predominantly congruent trials (75% congruent condition) are more likely to be reflected
by increased errors rather than an overall increase in response time latencies (Kane & Engle, 2003).
By contrast, when preceding trials are predominantly incongruent (12,5% congruent condition),
performance deficits on incongruent trials are more likely to be manifest in a shift towards slower
response time latencies rather than increased errors. Because we assumed that action versus state
orientation moderates the vulnerability to goal neglect under high demands, we expected the effects
in Study 4.4 to emerge in errors rather than response latencies.
To induce varying levels of demand, we induced a prospective memory load among half of
the participants. Specifically, we told participants in the high-demanding condition that they would
have to perform a task at the end of the experimental session for which they could earn an extra
financial reward. We reasoned that this instruction would strain working memory (Goschke &
Kuhl, 1993; Jostmann & Koole, in press; Chapter 2; Kuhl & Helle, 1986) and thereby give rise to a
demanding context. Participants in the low-demanding condition did not receive any hints about an
upcoming task. We expected that the prospective memory load would trigger different mobilization
of control resources among action- versus state-oriented participants, such that prospective memory
load lowers Stroop interference among action-oriented compared to state-oriented participants.

Method
Participants and Design
Participants were 155 paid volunteers at the Vrije Universiteit Amsterdam (52 men and 103
women, average age 20). The experimental design was 2 (orientation: action vs. state; between
participants) x 2 (prospective load: high vs. low; between participants) x 2 (congruency proportion:
75% congruent vs. 12,5% congruent, between participants). Fourteen participants failed to pass a
colorblindness test and were therefore removed from the dataset. The main dependent variables
consisted of participants’ average response latencies and errors in a Stroop task.
Procedure
The general procedure and the equipment were similar to Studies 4.1 and 4.3. Participants
were randomly assigned to one of the four experimental conditions (prospective load – 75%
congruent: n = 35; prospective load – 12,5% congruent: n = 37; no prospective load – 75%
congruent: n = 34; no prospective load – 12,5% congruent: n = 35). Participants started by filling
out some questionnaires, which contained our assessment of individual differences in action versus
state orientation (KR 20 = .77). Based on their responses, eighty-four participants were classified as
state-oriented, and seventy-one participants were classified as action-oriented.4.5 Participants moved
on with a study that contained our manipulation of prospective memory load. After this, participants
continued with the Stroop task, which served as our measure of cognitive control. Next, participants
were tested for colorblindness, after they were paid, debriefed, and thanked for their participation.
Prospective Memory Load Manipulation. After the individual differences assessment, we
manipulated prospective memory load. The procedure, which was developed by Koole and
Jostmann (2004), required participants to first solve a number of simple arithmetic sums. During
each sum, participants had to add up three one- or two-digit numbers and type in the correct
response. After participants had solved one practice sum, they were given 2.5 minutes to solve as
many sums as possible. During the entire task, the remaining time was displayed on the computer
When The Going Gets Tough… 101
screen. After 2.5 minutes had passed, participants were given feedback regarding the number of
sums they had solved correctly. Subsequent to the feedback, the prospective load was induced.
Participants in the prospective load condition were told that there would be a second block
of arithmetic sums. Participants were further informed that the level of difficulty and amount of
time for the second block were identical to the first block. However, during the second block,
participants could earn a financial bonus if they improved their performance compared to the first
block. Specifically, participants would receive a bonus of €1.00 if they solved at least 10% more
sums and a bonus of €2.50 if they solved at least 25% more sums during the second block. It was
further explained that the second block of arithmetic sums would be preceded by several unrelated
studies, ostensibly to avoid fatigue. These unrelated studies included our measure of cognitive
control. Participants in the no prospective load condition were told that they had solved more sums
during the first block than the average participant within the same amount of time. Therefore, they
received an extra bonus of €2.50. The unexpected reward was provided to keep the total financial
compensation constant across conditions. In the no prospective load condition, no mention was
made of a second block of arithmetic sums. All participants completed a second block of arithmetic
sums after the Stroop task.
Stroop task
The Stroop task, which was based on Kane and Engle (2003), was similar to Study 4.1 with
the following exceptions: Specifically, the task consisted of 160 trials, 60 of which were critical for
analysis. The remaining 100 trials were filler trials, which, however, were not identifiable by the
participants as fillers. Trials were randomly defined as respectively filler trials or critical trials
before the experiment was conducted. All analyses reported in the Results section include only
critical trials. (Analyses including critical trials and filler trials revealed equivalent results.)
Participants saw 20 critical trials of each trial type (incongruent, neutral, congruent). In the 12,5%
congruent condition, filler trials were incongruent. Participants in the 12,5% condition thus saw 20
When The Going Gets Tough… 102
congruent trials, 20 neutral trials, and 120 incongruent trials. By contrast, in the 75% congruent
condition, filler trials were congruent. Accordingly, participants in the 75% congruent condition
saw 120 congruent trials, 20 neutral trials, and 20 incongruent trials. All color words and ink colors
were equally represented across filler and critical trials (except for the neutral letter string XXXX,
which was only presented during critical trials.) The presentation of all 160 trials varied randomly
for each participant.
Results
Manipulation Checks. After participants had completed the second block of arithmetic sums,
we asked participants to indicate why they would receive an extra bonus. One hundred thirty-seven
participants (96.5% of the entire sample) provided the correct answer. Rerunning the main analyses
without the five participants who failed this test (3.5% of the entire sample) yielded no
substantively different results, so we retained them in the dataset. We further assessed how
participants currently felt (1 = very bad, 9 = very good) before the prospective load manipulation,
and how they felt directly after the manipulation but before the Stroop task. To obtain an index of
mood change as a function of prospective load, we subtracted participants’ mood ratings before the
manipulation from their mood ratings after the manipulation with higher scores indicating greater
mood improvement (Grand M = .49). A 2 (orientation) x 2 (prospective load) ANOVA revealed
greater mood improvements when prospective load was absent rather than when it was present (M =
.90 vs. M = .10), F(1, 137) = 6.76, p < .02, ηp2 = .05. No effects involving orientation occurred, all
Fs < 1. Mood improvements were not related to Stroop interference in response latencies (r = -.01,
ns) or to Stroop interference in errors (r = -.02, ns).

Stroop Effect
Color Evaluation Latencies. Before analyzing response time latencies, we removed
erroneous responses (2.7% of all responses) and responses faster than 300 ms (4.6% of all
responses) from the dataset. On average, participants’ responses on neutral trials were faster than
responses on incongruent trials, F(1, 140) = 46.24, p < .001, ηp2 = .25 (M = 532 vs. M = 594). In
addition, average responses on congruent trials were faster than responses on neutral trials, F(1,
140) = 36.36, p < .001, ηp2 = .21 (M = 506 vs. M = 532). Thus, color evaluation latencies revealed
evidence of both interference and facilitation. Next, we subtracted participants’ mean response
latencies on neutral trials from participants’ mean response latencies on incongruent trials to obtain
an index for Stroop interference. A 2 (orientation: action vs. state) x 2 (prospective load: high vs.
low) x 2 (congruency proportion: 75% congruent vs. 12,5% congruent) ANOVA on Stroop
interference yielded a significant main effect of congruency proportion, F(1, 133) = 7.77, p < .007,
ηp2 = .06. There was less Stroop interference in the 12,5% congruent condition than in the 75%
congruent condition (M = 30 vs. M = 97). The effect of congruency proportion was qualified by
orientation nor prospective load, all ps > .11.
Errors. Initial analysis revealed that participants conducted more errors on incongruent trials
than on neutral trials, F(1, 140) = 31.60, p < .001, ηp2 = .18 (M = .98 vs. M = .33). Participants’
errors on neutral trials did not differ from those on congruent trials, F < 1 (M = .33 vs. M = .29).
Thus, error data revealed evidence of interference but no facilitation.
Next, we subtracted participants’ mean errors on neutral trials from participants’ mean errors
on incongruent trials to obtain an index for Stroop interference. We then analyzed Stroop
interference using a 2 (orientation) x 2 (prospective load) x 2 (congruency proportion) ANOVA,
which revealed a main effect of congruency proportion, F(1, 133) = 19.43, p < .001, ηp2 = .13. On
average, Stroop interference was lower in the 12,5% congruent condition than than in the 75%
congruent condition (M = .18 vs. M = 1.15). However, this main effect was qualified by the
When The Going Gets Tough… 105
predicted three-way interaction between orientation, prospective load, and congruency proportion,
F(1, 133) = 6.35, MSE = 1.607, p < .02, ηp2 = .05. Relevant means are displayed in Table 4.4.
We proceeded with separate analyses for the 75% congruent condition and the 12,5%
congruent condition. Recall that we hypothesized that effects of orientation and prospective load on
cognitive control were caused by goal neglect. Accordingly, effects of orientation should especially
be apparent when prompts were absent, that is, in the 75% congruent condition. Consistent with
this, a 2 (orientation) x 2 (prospective load) ANOVA found no significant effects in the 12,5%
congruent condition, all ps > .2. By contrast, the same 2 (orientation) x 2 (prospective load)
ANOVA in the 75% congruent condition yielded a significant two-way interaction between
orientation and prospective load, F(1, 65) = 4.94, p < .04, ηp2 = .07. When prospective load was
present, state-oriented participants displayed greater Stroop interference than action-oriented
participants, F(1, 133) = 5.33, p < .03, ηp2 = .04 (M = 1.80 vs. M = .80). However, when
prospective load was absent, the pattern was reversed. State-oriented participants showed a
marginally smaller Stroop interference effect than action-oriented participants, F(1, 133) = 2.97, p =
.087, ηp2 = .04 (M = .58 vs. M = 1.33).
Another way of interpreting the orientation by prospective load interaction in the 75%
congruent condition is to note that, among state-oriented participants, Stroop interference was
higher when prospective load was present rather than absent, F(1, 133) = 9.04, p < .004, ηp2 = .06.
Among action-oriented participants, however, we found a non-significant reversal, such that Stroop
interference was greater when prospective load was absent rather than present, F(1, 133) = 1.33, p =
.26, ηp2 = .01.
Supplementary Analyses. Effects on Stroop interference in errors remained unchanged when
we controlled for Stroop interference in response latencies. Thus, there was no indication for a
speed/accuracy trade-off. Moreover, effects on Stroop interference in errors remained unchanged
when we controlled for the number of solved sums during the first arithmetic task (Grand M =
When The Going Gets Tough… 106
14.2), or for mood improvements induced by the prospective load manipulation (Grand M = .49).
Finally, for each participant, we computed an index of performance improvement by subtracting the
number of correctly solved arithmetic sums during the first block from the number of correctly
solved sums during the second block. Action- versus state-oriented participants displayed similar
performance improvements during the second block of arithmetic sums (Grand M = .7). Stroop
interference in errors was not affected by performance improvements.
Discussion
The results of Study 4.4 illuminate some of the mechanisms through which action versus
state orientation moderates the impact of demands on cognitive control. In line with a goal neglect
account, action versus state orientation moderated cognitive control when no prompts for cognitive
control were available in the 75% congruent condition. In addition, the effects of action versus state
orientation emerged on errors rather than response latencies. Previous work suggests that, in the
context of the paradigm used in Study 4.4, errors are the most sensitive index of goal neglect
processes (Kane & Engle, 2003). Taken together, goal neglect appears to be a critical mechanism
that explains why action versus state orientation moderates the impact of demands on cognitive
control (cf. Jostmann & Koole, in press).
When the task context discouraged goal neglect by providing prompts (i.e., in the 12,5%
congruent condition), neither errors nor response latencies revealed any differences in cognitive
control as a function of demands and action versus state orientation. Previous work indicates that
the availability of prompts in the paradigm used in Study 4.4 does not remove the competition
between the competing ink color and word color dimensions (Kane & Engle, 2003). Accordingly,
the basic capacity for competition resolution seems to remain unaffected by action versus state
orientation (cf. Baumann & Kuhl, 2005; Dibbelt, 1997; Fuhrmann & Kuhl, 1998). However, this
conclusion may need to be qualified in light of the potential occurrence of sequence or practice
effects during repeated response activations (cf. Mayr, Awh, & Laurey, 2003). To the extent that
When The Going Gets Tough… 107
sequence or practice effects have reduced the required amount of cognitive control below a critical
level in the 12,5% congruent condition, participants' action versus state orientation may have
become irrelevant. Future research may address this possibility by including a trial type that is more
resistant against practice effects (see the difficult trials in Study 4.2), or by increasing the number of
different ink colors to reduce the likelihood of response repetitions (cf. Kerns, Cohen, MacDonald,
Cho, Stenger, & Carter, 2004).
In the low-demanding condition in Study 4.4, participants experienced a significant mood
improvement. Accordingly, one might wonder whether the effects in Study 4.4 could be
alternatively explained by mood improvements in the low-demanding condition rather than, as we
suggest, by prospective load in the high-demanding condition. Supplementary analyses render a
mood-based explanation less likely because mood improvements were not related to Stroop
interference. In addition, all analyses on Stroop interference remained intact when we statistically
controlled for mood improvements. Finally, unlike Stroop interference, mood improvements after
the demand induction were not affected by action versus state orientation (cf. Koole & Jostmann,
2004, Experiment 1). We therefore conclude that the effects in Study 4.4 were unlikely to result
from mood improvements in the low-demanding condition.
General Discussion
In the present research, we investigated how action versus state orientation regulates the
impact of high demands on cognitive control. Across four studies, we found evidence that high
demand leads to greater cognitive control in Stroop tasks among action- compared to state-oriented
individuals. By contrast, low demand led action-oriented individuals to display comparable or lower
levels of cognitive control compared to state-oriented individuals. Our findings were consistent
across different manipulations of demands. Action- compared to state-oriented participants
displayed greater cognitive control after the performance of a demanding task (Studies 4.1 and 4.2),
and under prospective load (Study 4.4). Notably, action versus state orientation moderated cognitive
When The Going Gets Tough… 108
control even in response to real-life demands (Study 4.3). Taken together, action versus state
orientation moderates cognitive control across different operationalizations of demand.
We identified goal neglect as a key mechanism that explains the functional differences
between action-oriented and state-oriented individuals under high demand. Specifically, high
demand in Study 4.4 led action-oriented participants to display better cognitive control compared to
state-oriented participants when task conditions were conducive to goal neglect. Because goal
neglect reflects an insufficiency of working memory during cognitive control (Kane & Engle,
2003), our findings suggest that improved cognitive control under high demands is due to more
efficient use of working memory among action- compared to state-oriented individuals. This idea is
consistent with recent findings that under high demands action-oriented individuals utilize their
working memory capacity more efficiently than state-oriented individuals as indicated by
individuals’ OSPAN scores (Jostmann & Koole, in press; Chapter 2). Taken together, action-
oriented individuals seem to be better protected against goal neglect under high demand than state-
oriented participants.
The conditions that trigger action versus state orientation to regulate cognitive control
theoretically involve sustained working memory use. Such sustained use may be caused by
prolonged engagement in difficult tasks or persisting prospective load. Action versus state
orientation therefore should not be triggered by task difficulty per se but rather by the draining
effects of prolonged task difficulty. In line with this reasoning, action-oriented participants did not
outperform state-oriented participants on the difficult working memory task at the beginning of
Study 4.1 but only on the subsequent Stroop task. Moreover, we found no performance differences
in Study 4.2 between action- and state-oriented participants on difficult trials in the first two blocks
but only in the third block after task engagement had been progressed. In short, action versus state
orientation regulates cognitive control when difficult task conditions persist over time. The
importance of prolonged task difficulties may be related to the activity of dopaminergic circuits in
When The Going Gets Tough… 109
the brain, which become depleted after prolonged activation of working memory (cf. Lorist et al.,
2005).
The effects of action versus state orientation have some similarities with the effects of
working memory capacity. Both constructs moderate cognitive control, especially under conditions
that encourage goal neglect (Kane & Engle, 2003). However, there also exist important differences.
Unlike individuals high in working memory capacity, action-oriented individuals displayed
cognitive control improvements only under high-demanding circumstances. Under low-demanding
circumstances, action-oriented individuals performed equally well (Studies 4.2 and 4.4) and
sometimes even worse than state-oriented individuals (Study 4.3; cf. Koole et al., 2005). In
addition, action versus state orientation did not moderate cognitive control under conditions that
discourage goal neglect (Study 4.4). By contrast, such moderating effects have been reported for
working memory capacity under almost identical task conditions, although the effects were not
always robust across experiments (Kane & Engle, 2003). Finally, action versus state orientation
moderated cognitive control over and above individual differences in working memory capacity
(Study 4.1). In sum, although there exist some similarities between the two constructs, the effects of
action versus state orientation on cognitive control are conceptually and empirically distinct from
the effects of working memory capacity.
Based on the present research and recent findings (Jostmann & Koole, in press; Chapter 2;
cf. Kuhl, 2000), we suggest that individual differences in working memory capacity reflect general
limitations in cognitive control, whereas action versus state orientation reflects the ability to use
one’s working memory capacity efficiently to exert cognitive control under high demands.
Importantly, higher working memory efficiency makes it unnecessary for action-oriented
individuals to mobilize extra efforts (cf. Brehm & Self, 1989; Eysenck & Calvo, 1992). Under high
demands, increased effort mobilization during cognitive control may lead to subsidiary costs as
indicated by a speed/accuracy trade-off (Boksem, 2006; cf. Hockey, 1997). No such speed/accuracy
When The Going Gets Tough… 110
trade-off was found in the present research. It thus appears that action versus state orientation under
demands relates to differences in processing efficiency rather than capacity, or effort mobilization.
Limitations and Future Directions
The present research remains preliminary and therefore leaves many questions open for
further investigation. One important task for future research is to gauge the scope of the impact of
action versus state orientation on executive functions. One recent analysis suggests the separability
of three executive functions including mental set shifting, information updating, and inhibition of
prepotent responses (Miyake et al., 2000). The present research on cognitive control in Stroop tasks
has shown that action versus state orientation moderates the impact of high demands on the third set
of functions. Moreover, initial evidence from our laboratory suggests that action versus state
orientation also moderates the effects of high demands on more complex executive tasks including
the OSPAN task (Jostmann & Koole, in press; Chapter 2), or the Tower-of-Hanoi task (Jostmann,
Gieselmann, & Koole, 2004). Future research is needed to examine whether the effects of action
versus state orientation also apply to other executive functions such as set shifting and updating.
The present findings might also be relevant for more applied research. The present research
revealed that state-oriented participants under high demands display some symptoms that are
characteristic of depression, such as lack in initiative (Hertel & Hardin, 1990) or “forgetting” to
enact one’s intentions (Kuhl & Helle, 1986). Although the present research focused exclusively on
non-clinical populations, PSI theory (Kuhl, 2000; Kuhl & Beckmann, 1994a) suggests a link
between state orientation and vulnerability to depression. Future research on the antecedents of
depression might therefore benefit from considering the role of state orientation and chronically
elevated levels of demand. Moreover, the relative performance decrements among state-oriented
individuals under high demands raise the question how working, learning and testing conditions
should be structured in order to provide ideal environments for employees or students with an
action versus state orientation, respectively (cf. Diefendorff et al., 1998, 2000). In sum, applied
When The Going Gets Tough… 111
research might profit from considering the role of action versus state orientation under high
demands.
Concluding Remarks
The capacity to exert cognitive control is a fundamental prerequisite for intentional action.
The present research suggests that at least some people may be capable of strategically adjusting
their capacity for cognitive control to the demands of the situation. Indeed, we found consistent
evidence that action-oriented individuals strengthen their cognitive control under high-demanding
circumstances in comparison with state-oriented individuals. As such, action orientation may be a
vital resource in the regulation of cognitive control under demanding conditions.

Chapter 5
Dealing with Demands
Conclusions, Integration, and Implications
The present dissertation highlights the role of action control in coping with high demands. In
Chapter 1, I defined action control as the mental processes that allow people to form, maintain, and
implement (or disengage from) their intentions. Action control presumes effective management of
working memory. High demands involve sustained activation of working memory, which reduces
the effectiveness of this system. I therefore reasoned that effective action control should moderate
the psychological impacts of high demands. Accordingly, action-oriented individuals, who are
highly skilled at action control, may shield themselves more effectively against high demands than
state-oriented individuals, who are less skilled at action control.
Because action control operates at a global level of psychological functioning, action control
should moderate the impact of high demands across many major domains of human functioning,
including cognition, affect, and behavior. Chapter 1 reviewed previous research that provided some
suggestive support for this notion. This previous research suffered from important limitations, and
no research systematically examined how action versus state orientation moderates the impact of
high demands on cognition, affect, and behavior. I therefore conducted a program of research aimed
at clarifying the role of action versus state orientation in cognitive, affective, and behavioral
shielding against high demands. This research is described in Chapters 2 to 4.
In this final chapter, I summarize the main theoretical conclusions that can be drawn from
Chapters 2 to 4. In addition, I make an initial attempt to integrate the findings that emerged from the
present dissertation research into a coherent theoretical model. This model, which is based on recent
models of intentional action (Kuhl, 2000) and working memory (Braver & Cohen, 2000; Cohen,
Braver, & Brown, 2002), attributes a central role to the updating function of working memory.

Action Orientation and Cognitive, Affective, and Behavioral Shielding
Cognitive shielding refers to the extent to which people are able to protect their working
memory resources from the burden of demands. Chapter 2 found evidence that action- compared to
state-oriented individuals display improved cognitive performance under high demands on tasks
that rely on working memory. High demands were induced by having participants visualize a
demanding relationship, whereas low demands were induced by having participants visualize an
accepting relationship (Baldwin & Sinclair, 1996). Visualizing a demanding relationship led to
higher operation span (OSPAN) scores (Study 2.1; cf. Turner & Engle, 1989) and greater intention
memory in a postponed intention task (Study 2.2; cf. Goschke & Kuhl, 1993) than visualizing an
accepting relationship among a action-oriented individuals. By contrast, state-oriented individuals
had lower OSPANs (Study 2.1) and smaller intention memory (Study 2.2) after visualizing a
demanding compared to an accepting relationship. In sum, action- but not state-oriented individuals
diplay improved cognitive shielding under high demands.
Affective shielding refers to the extent to which people are able to maintain or restore a
positive affective state, particularly under demanding conditions. In Chapter 3, I found evidence
that action-oriented individuals are also more effective at affective shielding than state-oriented
individuals (cf. Koole & Jostmann, 2004). Using a subliminal priming task (Chartrand, Van Baaren
& Bargh, 2006), participants in Study 3.1 were exposed to schematic faces with either an angry,
neutral, or happy expression. Among participants who were primed with angry faces, those with an
action orientation showed a more positive affective reaction than those with a state orientation on a
basic affect measure (Tesser, Millar, & Moore, 1988). No similar affective differences between
action- and state-oriented individuals were found among participants who were primed with neutral
or positive faces. Moreover, state-oriented individuals displayed a more negative affective reaction
when they were primed with angry compared to happy faces, whereas no such effect was found
among action-oriented individuals. Taken together, Chapter 3 found evidence that action- compared
When The Going Gets Tough… 114
to state-oriented individuals display more efficient affective shielding, even when affect is
processed at unconscious levels.
Behavioral shielding refers to the extent to which people are able to enact their intentions.
Chapter 4 operationalized behavioral shielding as participants’ ability to exert cognitive control in
Stroop tasks, which required participants to override a strong but task inappropriate response
tendency. High demands were manipulated by having participants perform a difficult task that
strains working memory (Studies 4.1 – 4.2; cf. Kazén & Kuhl, 2005; Turner & Engle, 1989), or by
inducing a norm for future task performance (Studies 4.4; cf. Koole & Jostmann, 2004). Moreover,
Chapter 4 also measured the level of demand in participants’ personal lives (Study 4.3; cf.
Baumann, Kaschel, & Kuhl, 2005). Across these different demand manipulations, high demands led
to greater cognitive control among action- compared to state-oriented individuals. No similar
differences in cognitive control were found under low demands. Chapter 4 thus found evidence that
action- compared to state-oriented individuals are more effective at behavioral shielding under
demanding conditions.
Chapter 4 further shed light on one mechanism whereby action orientation facilitates
behavioral shielding under high demands. More specifically, improved behavioral shielding under
high demands among action- compared to state-oriented individuals was found to depend on
whether behavioral shielding requires the active representation of an intention in working memory
(Study 4.4). When the task intention to ignore the word meaning during a Stroop trial was prompted
by a large proportion of incongruent Stroop trials (cf. Kane & Engle, 2003), action- versus state-
oriented individuals displayed no differences in cognitive control in response to varying levels of
demand. By contrast, when participants had to maintain the task intention in working memory
because no external prompts were available, high demands led to increased cognitive control among
action- compared to state-oriented individuals. Taken together, the findings of Study 4.4 suggest
When The Going Gets Tough… 115
that behavioral shielding among action- versus state-oriented individuals under high demands
depends on whether people can utilize their working memory efficiently to guide cognitive control.
An Integrative Model of Action Control and Coping with Demands
The central theme of the present dissertation is that action-oriented individuals shield
themselves better than state-oriented individuals against the psychological costs of high demands in
cognition, affect, and behavior. In psychology, cognition, affect, and behavior are widely
recognized as the main components of psychological functioning. It thus appears that action versus
state orientation thus regulates the psychological impact of demands across all main domains of
human functioning. This very general influence of one variable might be considered surprising,
because many psychologists today focus on processes and phenomena that are highly specific to
particular paradigms and experimental tasks. How can a single variable like action versus state
orientation predict such broad aspects of human functioning?
One explanation for the observed generality across domains is that the different types of
shielding are related to another because they each contribute to intentional action control.
Specifically, cognitive shielding facilitates the formation and maintenance of intentions. Moreover,
affective shielding processes block negative mood and the activation of intention-inappropriate
action tendencies. Finally, behavioral shielding facilitates the implementation of intentions by
overriding competing impulses. Because overall action control can only be effective to the extent
that all subcomponents function effectively, it is likely that improved shielding in one domain may
also lead to improved shielding in other domains. In the following, I will further elaborate on this
idea by proposing an integrative model of action control and coping with high demands.
When The Going Gets Tough… 116
Figure 5.1. A Functional Model of Intentional Action Control
(Adapted from PSI theory; Kuhl, 2000; Concepts in Italics are Added by the Author).
This theoretical integration is based on a recent model of intentional action control that has
been elaborated in personality systems interactions (PSI) theory (Kuhl, 1984, 2000, 2001).
According to PSI theory, effective action control depends on the interaction between high-level
mental systems like working memory (and in particular intention memory; cf. Kazén & Kuhl, 2005)
and low-level behavioral output systems (see Figure 5.1). When the neuro-cognitive pathway
between working memory and behavioral output systems is inhibited, no information between these
two types of systems can be exchanged. In such cases, people’s behavior is likely to be determined
by automatic behavior routines. However, when the pathway is facilitated, intentions that are
represented in working memory can be released to make them accessible for implementation
through behavioral output systems. Moreover, pathway facilitation also allows perceptual
information to enter working memory thereby changing its contents. Such perceptual information
may include sensory information but also information about personal goals and needs. Taken
together, pathway facilitation leads to what recent neuropsychological models (Braver & Cohen,
2000; Cohen et al., 2002) would refer to as the updating of working memory.
PSI theory (Kuhl, 2000, 2001) further proposes that the pathway between working memory
and behavioral output systems is mediated by positive affect. Specifically, high positive affect

(Intention Memory)
When The Going Gets Tough… 117
facilitates the pathway, whereas low positive affect leads to its inhibition (for experimental
evidence, see Kazén & Kuhl, 2005; Kuhl & Kazén, 1999). On a neurological level, high positive
affect has been associated with increased activity of the neurotransmitter dopamine (Ashby, Isen, &
Turken, 1999). Consistent with the predictions of PSI theory regarding the role of positive affect,
recent neuropsychological models (Braver & Cohen, 2000; Cohen et al., 2002) suggest that
increased dopaminergic activity in relevant brain regions (e.g., prefrontal cortex) facilitates the
updating of working memory. Recent research indeed suggest that the experimental induction of
high positive affect, and a genetic disposition for high dopaminergic activity both facilitate
intention implementation in a cognitive control task on the one hand, and the uptake of new
information in working memory on the other hand (Dreisbach et al. 2005; Dreisbach & Goschke,
2004; cf. Olivers & Nieuwenhuis, 2006). Taken together, high positive affect or high dopaminergic
activity facilitate the updating of working memory.
Based on the foregoing analysis, I suggest that successful action control depends on how
well people can update their working memory. This updating mechanism, in turn, may explain the
threefold effect on action control including cognitive, affective, and behavioral effects. Specifically,
updating may contribute to cognitive shielding because, on the one hand, it causes old and
potentially irrelevant information to be erased and, on the other hand, it allows new and potentially
more relevant information to enter working memory.5.1 Moreover, because updating is related to
increased positive affect, updating may also help people to shield against negative affect. Finally,
updating may contribute to behavioral shielding because it makes intentions that are represented in
working memory, accessible to guide behavioral output. If this line of reasoning is correct, the
effects of high demands on the shielding of cognition, affect, and behavior may be mediated by the
updating function of working memory.
Under high demands, the updating function likely becomes temporarily impaired. The
reason is that high demands involve the sustained activation of working memory, which, in turn,
When The Going Gets Tough… 118
leads to declines in dopaminergic activity. In line with this idea, recent research suggests that
cognitive impairments after prolonged engagement in a cognitive control task are caused by
decreases in dopaminergic activity (Lorist, Boksem, & Ridderinkhof, 2005). To the extent that
working memory updating is involved in cognitive control (cf. De Jong, Berendsen, & Cools, 1999;
Kane & Engle, 2003), the findings of this research thus support the idea that high demands impair
the updating function of working memory. Consequently, an effective way to cope with high
demands is thus to maintain the updating function of working memory. Because the updating
function is an essential part of action control, high skills at action control among action-oriented
individuals lead to more effective coping with high demands than low action control skills among
state-oriented individuals.
In sum, the “updating model” of action control and coping with high demands holds that
effective action control involves the updating function of working memory. Efficient updating of
working memory contributes to triple shielding of cognition, affect, and behavior. Updating is
facilitated by increased positive affect and high activity of its neurological substrate dopamine.
Under high demands, dopaminergic activity declines thereby leading to a transient impairment of
the updating function. Coping with high demands requires people to restore the updating function.
Accordingly, the updating model predicts that action-oriented individuals cope better with high
demands than state-oriented individuals because they can regulate the updating function more
effectively under high demands than state-oriented individuals.
The updating model integrates the findings of the present dissertation and links them to
contemporary discussions of action control and working memory. Although the ultimate validity of
the model remains to be tested by future research, the major findings of present dissertation are
consistent with its assumptions. For instance, Chapter 2 revealed that action- but not state-oriented
individuals utilize their working memory capacity more efficiently under high compared to low
demands. Moreover, Chapter 3 found that action- compared to state-oriented individuals are better
When The Going Gets Tough… 119
able to regulate their affective states (cf. Koole & Jostmann, 2004). The regulation of one’s
affective states can be expected to increase the updating of working memory. Finally, Chapter 4
found that improved cognitive control under high demands among action-oriented individuals only
occurred when cognitive control relied heavily on working memory because external prompts were
lacking. To the extent that efficient use of working memory involves updating, the present findings
suggest that action- compared to state-oriented individuals can better update working memory
under high demands.
Theoretical Implications
The present dissertation examined coping with demands using well-established and
validated measures of high-level functioning including the OSPAN task of working memory and
the Stroop task. These tasks have been used in various psychological sub-disciplines such as, for
instance, cognitive psychology or cognitive neuroscience. As such, the present dissertation helps to
bridge the literature on action control and coping with high demands with existing cognitive and
neuropsychological theories of executive functioning. The present dissertation thus indicates that
much is to be gained from a continued theoretical exchange between the areas of intentional action
control, coping with demands, and cognitive neuroscience.
A powerful theoretical approach in cognitive neuroscience is formed by recent neuro-
cognitive models of working memory regulation (Braver & Cohen, 2000). As outlined above, the
process whereby working memory gets updated could provide an integrative theoretical framework
for understanding the effects of action versus state orientation on coping with demanding situations.
Testing the predictions of the updating model in the context of coping with high demands may be
an important task for future research. One important prediction that could be tested during future
research is the notion that coping with high demands depends on how efficient people can update
their working memory. Because updating is linked to the up-regulation of positive affect (or
dopaminergic activity), one can assume an important mediating role of affect regulation during the
When The Going Gets Tough… 120
coping process (cf. Kuhl, 2000). In the context of the present research, one would predict that affect
regulation mediates the effects of action versus state orientation and high demands on working
memory (cf. Chapter 2) and on cognitive control (cf. Chapter 4). For instance, improved cognitive
control in Stroop tasks among action- compared to state-oriented individuals under high demands
should be mediated by more effective affect regulation among action-oriented individuals.
The mediating role of affect regulation in the effects of action versus state orientation is
theoretically plausible (Braver & Cohen, 2000; Koole & Kuhl, in press; Kuhl, 2000). However, it
may not be easy to detect empirically. A possible problem is that many measures of affect
regulation (e.g., the affective Simon task; De Houwer & Eelen, 1998) interfere with the regulatory
process and therefore decrease the possibility to find effects on subsequent measures of action
control. Likewise, it might be difficult to detect mediating effects of dopaminergic activity because
dopamine cannot be measured directly in human participants.
However, recent research suggests a promising way to assess dopaminergic activity
unobtrusively through its behavioral correlates. Specifically, dopaminergic activity correlates with
spontaneous eye blinks, which makes the assessment of spontaneous eye blinks through video
observation, EMG, or EEG registration a potential way to measure dopaminergic activity (Bacher &
Smotherman, 2004; Dreisbach et al., 2005). Another unobtrusive way to measure dopaminergic
activity may be to assess dopamine gene polymorphisms (i.e., the DRD4 exon III 4/7 genotype;
Dreisbach et al., 2005). Taken together, using unobtrusive measures of dopaminergic activity such
as spontaneous eye blinks or gene polymorphisms may be fruitful way to examine the predicted
affective-dopaminergic mediation effects on coping with high demands.
On a more global level, the insights of the present dissertation may inform different research
fields that examine self-regulation processes that seem closely related to working memory function.
For instance, social psychological research on so-called “ego-depletion” (Muraven & Baumeister,
2000; Schmeichel, Vohs, & Baumeister, 2003), neuro-cognitive research on mental fatigue (Lorist,
When The Going Gets Tough… 121
Klein, Nieuwenhuis, De Jong, Mulder, & Meijman, 2000; Van der Linden, Frese, & Meijman,
2003), and classic coping research (cf. Hockey, 1997; Zeidner & Endler, 1996) are conceptually
and methodologically distinct areas of research. However, the relevant empirical phenomena
display some important similarities in that they all involve drops in performance under high
demands. One intriguing issue for future research is therefore whether similar or different processes
are involved during coping with, for instance, ego depletion and coping with mental fatigue.
On the basis the present dissertation, it would be informative to consider the role of action
versus state orientation in phenomena such as ego depletion. Typical ego depletion studies measure
how long people can persist on a tiring task, such as squeezing a handgrip (cf. Martijn, Tenbült,
Merckelbach, Dreezens, & De Vries, 2002; Muraven, Tice, & Baumeister, 1998). Such tasks
require participants to inhibit their impulses (e.g., giving up on the physical exercise). However,
they do not necessarily require participants to maintain an explicit intention representation in
memory because the intention is already prompted by the task context (e.g., doing the exercise).
The findings of the present dissertation suggest that state- compared to action-oriented individuals
have no more difficulties to exert cognitive control under high demands when the task intention is
externally prompted (see particularly Chapter 4). As such, the present perspective suggests that
state-oriented individuals may perform equally well or even better than action-oriented individuals
in many ego depletion tasks (cf. Baumann & Kuhl, 2005; Fuhrmann & Kuhl, 1998). Although this
provocative hypothesis remains to be tested empirically, one can conclude that considering the
findings of the present dissertation may contribute intriguing new insights to other research on self-
regulation.
Practical Implications
The findings of the present dissertation also have practical implications. One major set of
findings of the present dissertation is that individuals vary widely in their ability to cope with
demands. The same intervention that may help one group of individuals is likely to undermine the
When The Going Gets Tough… 122
performance of another group of individuals. Thus, the results of the present dissertation strongly
suggest that individual differences in specific coping abilities should be taken seriously. Imposing a
uniform task structure upon both action- versus state-oriented individuals may well result in sub-
optimal performance for either group of individuals. The most optimal interventions will tailor task
settings to the specific characteristics of the individuals.
State-oriented individuals seem to warrant special attention when it comes to coping with
demands. The present dissertation found repeatedly that state-oriented individuals’ inability to
utilize their mental capacities efficiently under high demands (for instance, see Chapter 2, Studies
2.1 – 2.2). These findings converge with field studies showing that state-oriented individuals’
inability to utilize their mental capacities efficiently under high demands may lead to performance
impairments in many everyday achievement settings such as at work or during one’s study
(Bossong, 1998; Diefendorff, Hall, Lord, & Strean, 2000). The question therefore arises how state-
oriented individuals can be helped to meet their goals more effectively.
Before I turn to more practical considerations, it is important to recognize that high
performance of the individual under high demands is valued especially in modern Western society.
There exist other societies, for instance, who place greater value on virtues such as self-sacrifice or
collective rather than individual performance (cf. Markus & Kitayama, 1991). As such, having a
state orientation may be become more problematic the more a society or culture values high
effectiveness under high demand. The adaptiveness of state orientation may indeed be considered
from an interpersonal or group level. Specifically, it is possible that state-oriented individuals’
hesitation is adaptive on a group level as, for instance, when it prevents the premature
implementation of erroneous group decisions (for initial evidence, see Haschke & Kuhl, 1995;
Olvermann, Metz-Göckel, Hannover, & Pöhlmann, 2004). Practitioners are thus advised to take a
broad perspective on the utility of action versus state orientation, and consider potential tradeoffs
When The Going Gets Tough… 123
between the interests of the individual and the interests of the broader social system within which
the individual functions.
It is also important to consider whether state orientation can sometimes be adaptive (cf.
Koole, Kuhl, Jostmann, & Vohs, 2005). The present research found that state-oriented individuals
sometimes outperform action-oriented individuals under low demands (for instance, see Chapter 2).
However, it is possible that such performance improvements were not due to greater processing
efficiency (cf. Eysenck & Calvo, 1992; Gray, Burgess, Schaefer, Yarkoni, Larsen, & Braver, 2005)
but to greater effort investment (cf. Kahneman, 1973). The problem with great effort investment is
that it may lead to resource depletion among state-oriented individuals (cf. Hockey, 1997; Muraven
& Baumeister, 2000). As such, the benefits of being state-oriented under low demands may only be
short-lived and backfire when resources are depleted.
In short, it seems likely that many state-oriented individuals will display significant
functional deficits under demanding conditions, deficits that these individuals would gladly do
without. As such, I will consider the potential merits of some strategies that might be used to help
individuals to cope with high demands. One radical strategy may be to eliminate demands
altogether from the lives of state-oriented individuals. This strategy seems difficult to realize,
because demands are an integral aspect of modern life. However, even more moderate strategies
that seek to reduce dermands as much as possible should be applied with caution. Some prior
research research suggests that self-regulatory resources such as action orientation are much like a
skill that has to be learned and trained (Schulte, Hartung, & Wilke, 1997; cf. Muraven, Baumeister,
& Tice, 1999). Thus, although reducing demands is likely to provide temporary relief to state-
oriented individuals, it may at the same time deprive these individuals from the opportunity to
increase their coping skills to deal with demanding situations in other contexts. Consequently, the
strategy of reducing or eliminating demands altogether may ultimately backfire for state-oriented
individuals.
When The Going Gets Tough… 124
In Chapter 4, Study 4.4, cognitive control among state-oriented individuals was greatly
facilitated by providing them with external prompts. Thus, applied settings may use external
prompts to help state-oriented students or employees to free up their working memory and thus to
maintain their behavioral efficiency under high demands. In more unstructured and unpredictable
situations, however, it will be useful to teach state-oriented individuals strategies to generate their
own idiosyncratic prompts and to form implementation intentions or action plans (cf. Gollwitzer,
1996).
It should further be noted that the functional impairments of state orientation should not
apply for tasks that can be executed on the basis of automatic behavior routines. Some
psychologists have argued that many of people’s daily activities can be performed on automatic and
routine levels (Aarts & Dijksterhuis, 2000; Bargh & Chartrand, 1999). As such, state-oriented
individuals may be able to function well during most daily activities. Moreover, even in cases that
people cannot rely on automatic processing state-oriented individuals may perform similarly well as
action-oriented individuals when external prompts are available (cf. Chapter 4). Because everyday
life is full of external prompts that remind people of what they should do such as traffic signs,
advertisements, calendars, alarm clocks, notebooks etc., state-oriented individuals may experience
little hinder under high demands when such prompts are present.
A final set of questions relates to whether and how state-oriented individuals might be
encouraged to become more action-oriented. According to PSI theory (Kuhl, 2000; cf. Koole, Kuhl,
Jostmann, & Finkenauer, 2006), action versus state orientation is not biologically determined but
develops from childhood experiences with demanding situations. As such, it is theoretically be
possible for a person to change from reacting in a predominantly state-oriented mode in demanding
situations towards a more action-oriented mode of responding (cf. Schulte et al., 1997). One
possible way to make people more action-oriented may be to expose them to moderate levels of
demands in order to inoculate them against higher levels of demands (cf. Bossong, 1998;
When The Going Gets Tough… 125
Meichenbaum & Deffenbacher, 1988). An effective way to implement such training may be to
focus on specific critical life domains such as work, education, or social relations, rather than trying
to improve someone’s overall action orientation across situations (cf.Diefendorff, Hughes, &
Kamin, 2001).
Concluding Remarks
In modern society, coping effectively with high demands is increasingly necessary for
managing one’s professional, academic, and social lives. The present dissertation found converging
evidence that coping effectiveness is intimately linked to intentional action control. Indeed, action-
oriented individuals were found to cope more effectively with high demands than state-oriented
individuals in terms of the functioning of working memory, affect regulation, and cognitive control.
As such, action versus state orientation represents a key factor in knowing who gets going when the
going gets tough.

1.2. I use the term “automaticity” to refer to mental and behavioral processes that are
unintended and that elude people’s conscious awareness. The issue of automaticity versus
controllability of human behavior is complex and subject to an ongoing debate, which is beyond the
scope of the present dissertation. The interested reader may further consult Goschke (2003), Kuhl
and Koole (2004), Monsell (1996), Moors and De Houwer (2006), and Wegner and Bargh (1998).
1.3. The terms “cognitive control”, “action control”, “executive control”, “voluntary
control”, “self-control”, “control”, and “volition” have often been used interchangeably in the
literature. In the present dissertation, I use the term “cognitive control” to refer to what Miyake and
colleagues (2000, p. 57) denote as “one’s ability to deliberately inhibit dominant, automatic, or
prepotent responses when necessary”. By contrast, I use the term “action control” more generally to
refer to the mental processes that lead to the formation, maintenance, and implementation of (or
disengagement from) an intention (cf. Kuhl & Goschke, 1994a).
1.4. The term “demand” has elsewhere been used in different ways to refer to conditions in
which people have to perform several mental operations simultaneously or in quick succession
(e.g., Beilock et al., 2004; cf. Pashler, 1994), or to refer to situations that people experience as
potentially threatening for their well-being or self-image (e.g., Blascovich & Mendes, 2000).
1.5. It seems likely that sudden declines in positive affect can have very similar effects on
working memory effectiveness as sustained working memory use. Such declines can either be
triggered directly through, for instance, externally presented aversive stimuli (cf. Study 3.1), or
When The Going Gets Tough… 127
indirectly through the activation of intention memory during prospective load (cf. Study 4.4; Kuhl,
2000; Kuhl & Kazén, 1999).
1.6. In the present dissertation, the most relevant dimension of the ACS-90 is demand-
related action versus state orientation (AOD). All examples and references are therefore related
specifically to AOD (except for Chapter 3). For the sake of brevity, I use the more general term
action versus state orientation throughout this dissertation to refer to AOD. Discussions of threat-
related action versus state orientation (AOT), another facet of the broader action orientation
construct, can be found in Chapters 2 – 4. The terms “demand-related” and “threat-related” action
versus state orientation were suggested by Koole and Jostmann (2004) to replace the original
“decision-related” and “failure-related” action versus state orientation, respectively (Kuhl, 1994a,
1994b). The new labels fit better with relevant constructs within PSI theory (Kuhl, 2000, 2001).

basic affect was significant, β = - .242, t(84) = - 2.25, p < .03.
3.3. We believe that the low reliability coefficient of the basic affect measure can be
explained by a peculiarity of our task. Specifically, task instructions informed participants that the
experimenters were interested in why some combinations of letters were evaluated more positively
than others. Presumably, these instructions had made participants believe that their preferences for
some of the stimuli should be expressed in comparison to other stimuli. As a consequence, a
relatively positive evaluation of a target stimulus might have been followed by a comparatively
negative evaluation of a subsequently presented target stimulus. Given the random order
presentation of the three stimuli, intercorrelations appeared to be rather weak.

article and is not suitable for citation. Note that an earlier version of Chapter 4 included an
additional study, which examined the impact of action versus state orientation and demands on the
gender priming effect (cf. Blair & Banaji, 1996). Because it is not clear whether the gender priming
effect is conceptually equivalent to the Stroop effect (cf. De Houwer, 2003; Kornblum, Hasbroucq,
& Osman, 1990), I dropped the study from the final version of this chapter.
4.2. Study 4.1 also examined the effects of individual differences in achievement motivation
on cognitive control. To this end, we used Elliot and McGregor’s (2001) goal achievement scale,
which differentiates between mastery-related achievement motivation (6 items; Cronbach’s Alpha =
.76), and performance-related achievement motivation (6 items; Cronbach’s Alpha = .68). We
found no significant correlations between action versus state orientation and mastery-related
achievement motivation (r = .14), or performance-related achievement motivation (r = -.10),
respectively. Moreover, a 2 (orientation: action vs. state; between participants) x 2 (mastery
motivation: high vs. low; between participants) ANOVA on Stroop interference in response
latencies revealed a significant main effect of orientation, F(1, 49) = 5.11, p < .03, ηp2 = .09, but no
effects involving mastery motivation, all Fs < 1.7. In addition, a 2 (orientation: action vs. state;
between participants) x 2 (performance motivation: high vs. low; between participants) ANOVA on
Stroop interference in response latencies revealed a significant main effect of orientation, F(1, 49) =
4.53, p < .04, ηp2 = .09, and a marginal effect of performance motivation, F(1, 49) = 3.18, p < .07,
ηp2 = .07. Participants with high performance motivation displayed somewhat more Stroop
interference than participants with low performance motivation (M = 99 ms vs. M = 69 ms). The
interaction term between orientation and performance motivation was not significant, F < 1. In sum,
the effects of action versus state orientation on cognitive control in Study 4.1 were independent of
individual differences in achievement motivation.

4.3. Following Kuhl (1994b), we included measures of threat-related action versus state
orientation (AOT) in Studies 4.1 – 4.4. Across Studies 4.1 – 4.4, we found no interactive effects of
AOT and demands on cognitive control. Therefore, we do not further report on this individual
difference.
4.4. We also examined our data in Studies 4.1 – 4.4 using participants’ responses on the
AOD subscale as a continuous variable in a regression approach. In Study 4.1, the effect of
orientation was significant even when we controlled for OSPAN scores, β = -.28, t(52) = -2.08, p <
.05, R2 = .09. In Study 4.2, we conducted a (trial difficulty) x (task duration) repeated measures
analysis with participants’ responses on the AOD subscale as a covariate. The analysis revealed a
significant interaction between trial difficulty, task duration, and the covariate, F(2, 72) = 4.87, p <
.02, ηp2 = .12. In Study 4.3, the (AOD) x (real-life demand) interaction was significant, β = -.30,
t(76) = -2.64, p < .02, R2 = .11. In Study 4.4, the (AOD) x (prospective load) x (congruency
proportion) interaction was significant, β = .17, t(140) = 2.07, p < .05, R2 = .18. Within the 75%
congruent condition, the (AOD) x (prospective load) interaction also reached the level of
significance, β = -.253, t(68) = -2.10, p < .05, R2 = .07.
4.5. In Study 4.4, we deviated from the normative split because of an otherwise
disproportionally unequal distribution of participants across cells. We based the classification of
participants as either action- versus state-oriented on the empirical rather than the normative
median. Participants with seven or less action-oriented responses on the AOD subscale were
classified as state-oriented, whereas the remaining participants were classified as action-oriented.
Rerunning the main analyses after exclusion of the mid-group of participants (i.e. participants who
had given six or seven action-oriented responses; n = 29) left the results intact. Specifically, an
(orientation) x (prospective load) x (congruency proportion) ANOVA revealed the predicted three-
way interaction, F(1, 105) = 4.43, p < .04, ηp2 = .04. A separate (orientation) x (prospective load)
ANOVA within the 75% congruent condition yielded the predicted two-way interaction, F(1, 49) =
When The Going Gets Tough… 131
3.90, p = .054, ηp2 = .07. The results in Study 4.4 were thus not dependent on the use of the
empirical versus the normative median. Moreover, when we conducted regression analyses on the
entire sample, we obtained equivalent results to an ANOVA approach (see Footnote 4.4).
5.1. Note that working memory should not erase old information that is still relevant.
Moreover, working memory should also not allow new but irrelevant information to enter. These
two situations are phenomenologically experienced as forgetfulness and distraction, respectively.
Working memory and the dopaminergic system thus have the paradoxical task of safeguarding
against irrelevant information but still remaining open for relevant information. How this task is
solved has not yet been fully understood (cf. Goschke, 2003). One suggestive possibility is the
existence of two antagonistic dopamine systems that become activated when information is
categorized as irrelevant or relevant, respectively. In line with this idea, Cohen and colleagues
(2002) recently suggested that so-called D1-receptors regulate tonic increases in dopamine thereby
protecting information in working memory. By contrast, D2-receptors regulate phasic increases in
dopamine thereby facilitating the updating of working memory with new information (cf.
Durstewitz et al., 1999).

Summary
High demands are a pervasive condition in many people’s professional, academic, and social
lives. High demands occur, for instance, when people have many pressing affairs simultaneously on
their mind. Because high demands can make people less successful at reaching their goals, it is
important to understand how people can cope effectively with high demands. The present
dissertation examines coping with high demands from an action control perspective (Kuhl, 1984,
2000). Action control refers to the mental processes that are involved in the formation,
maintenance, and implementation of (or disengagement from) an intention. Such processes rely on a
high-level working memory system that is partly located in the prefrontal cortex.
In the present dissertation, high demands refer to conditions that are characterized by
sustained use of working memory. Sustained use of working memory can lead to a transient decline
of its effectiveness. Because working memory effectiveness is a key function of action control,
strong action control skills may be an important factor in coping with high demands. Accordingly,
the present dissertation tested the hypothesis that individuals who are highly skilled at action
control, or action-oriented individuals, cope more effectively with high demands than individuals
who are less skilled at action control, or state-oriented individuals.
In three series of studies, I experimentally induced high versus low levels of demands or I
measured participants’ level of demand in their real lives. Coping effectiveness among action-
versus state-oriented individuals was measured across three major psychological domains including
cognition, affect, and behavior. In a first line of research (Chapter 2), action- compared to state-
oriented individuals were found to be better able at cognitive shielding as reflected by the efficiency
with which people can make use of their working memory capacity under high demands.
Specifically, action-oriented individuals displayed more efficient use of their working memory
capacity in an “operation span task” (Study 2.1) and a “postponed intention task” (Study 2.2) under
high compared to low demands. Among state-oriented individuals, I found the reversed pattern such
When The Going Gets Tough… 133
that high demands led to less efficient use of working memory than low demands. A second line of
research (Chapter 3) revealed that action-oriented individuals are also better able at affective
shielding as reflected by their positive affective reactions in response to subliminally primed
negative affect in comparison with state-oriented individuals’ reactions (Study 3.1).
In a third and final line of research, action- compared to state-oriented individuals were also
found to be better able at behavioral shielding (Chapter 4) as reflected by the ability to implement a
difficult intention. Specifically, in a series of “Stroop color evaluation tasks”, action-oriented
individuals were found to be better able to override a strong but inappropriate response tendency
(Studies 4.1 – 4.4). Across all three lines of research, improved performance among action-
compared to state-oriented individuals was found only under high but not under low demanding
conditions indicating that action compared to state orientation reflects better coping abilities rather
than better overall mental skills across conditions.
To integrate the findings, the present dissertation proposes the “updating model” of action
control and coping with high demands (Chapter 5). Based on recent neuro-cognitive theories of
working memory regulation (Braver & Cohen, 2000; Kuhl, 2000), the updating model suggests that
high demands inhibit the neuro-cognitive pathway between working memory and behavioral output
systems thereby rendering an updating of information between these two systems difficult. When
updating fails, working memory utilization becomes less efficient, and intentions become less
available to guide behavioral output. Furthermore, pathway inhibition is linked to decreased
dopaminergic activity and reduced positive affect. Taken together, failure to update working
memory is la likely reason for detrimental effects of high demands on different psychological
domains including cognition, affect, and behavior.
The updating model further suggests that action compared to state orientation facilitates the
updating function of working memory. A likely way how action orientation restores the updating
function is by upregulating positive affect (cf. Koole & Jostmann, 2004). The empirical test of this
When The Going Gets Tough… 134
assumption provides an important task for future research on effective coping with high demands.
Chapter 5 provides some ideas about how this task may be accomplished. In sum, the updating
model integrates the findings of the present dissertation with contemporary theories of working
memory regulation, and provides some promising perspectives for further research.

Samenvatting
Veel mensen komen tijdens hun werk, in hun studie, en in hun sociale leven geregeld onder
hoge psychische druk te staan. Hoge psychische druk ontstaat bijvoorbeeld als mensen veel
dringende aangelegenheden tegelijkertijd moeten regelen. Als gevolg hiervan zijn mensen vaak
minder succesvol in het bereiken van hun doelen. Gezien deze en andere potentiële gevolgen is het
belangrijk om te begrijpen hoe mensen op een effectieve manier kunnen omgaan met belastende
situaties die hoge psychische druk veroorzaken. Dit proefschrift onderzoekt deze vraag vanuit het
perspectief van de actie-controle theorie (Kuhl, 1984, 2000). Actie-controle verwijst naar de
mentale processen die betrokken zijn bij het vormen, vasthouden (of loslaten), en uitvoeren van
gedragsintenties. Deze processen maken allemaal gebruik van het zogenaamde werkgeheugen, een
geavanceerd mentaal systeem dat ten dele gelokaliseerd is in de prefrontale hersengebieden.
Een belangrijk kenmerk van belastende situaties is dat mensen aanhoudend gebruik moeten
maken van hun werkgeheugen. Door aanhoudend gebruik kan het werkgeheugen echter tijdelijk
uitgeput raken. Omdat het werkgeheugen een belangrijke functie heeft voor actie-controle, is het
aannemelijk dat mensen beter met druk kunnen omgaan naarmate zij bekwamer zijn in actie-
controle. In dit proefschrift heb ik de hypothese onderzocht dat mensen die bekwaam zijn in actie-
controle, of actiegeoriënteerde mensen, effectiever kunnen omgaan met psychische druk dan
mensen die minder bekwaam zijn in actie-controle, of toestandsgeoriënteerde mensen.
In drie reeksen onderzoeken heb ik bij actie- en toestandsgeoriënteerde proefpersonen hoge
of lage druk experimenteel geïnduceerd of de mate van druk in hun persoonlijke levens gemeten.
De effectiviteit in het omgaan met druk heb ik vervolgens op drie niveaus van psychologisch
functioneren gemeten: cognitie, affect, en gedrag. In een eerste reeks onderzoeken naar zogenaamde
cognitieve bescherming (Hoofdstuk 2) heb ik gevonden dat de efficiëntie van het werkgeheugen bij
actiegeoriënteerden beter is onder hoge dan onder lage druk, zoals bleek uit hun prestatie in de
zogenaamde “operatie-spanne taak” (Studie 2.1) en in de “uitgestelde intentie taak” (Studie 2.2). Bij
When The Going Gets Tough… 136
toestandsgeoriënteerden vond ik daarentegen efficiënter gebruik van het werkgeheugen onder lage
dan onder hoge druk. In een tweede onderzoekslijn naar affectieve bescherming (Hoofdstuk 3) vond
ik dat actiegeoriënteerden positievere affectieve reacties gaven dan toestandsgeoriënteerden nadat
ik bij hen onbewust negatief affect had geïnduceerd (Studie 3.1).
In een derde en laatste onderzoekslijn naar gedragsmatige bescherming (Hoofdstuk 4)
bleken actiegeoriënteerden moeilijke intenties beter uit te kunnen voeren dan
toestandsgeoriënteerden. In een reeks zogenaamde “Stroop kleurbenoemingstaken” (Studies 4.1 –
4.4) konden actiegeoriënteerden onder hoge druk een dominante maar onbedoelde respons beter
onderdrukken en een bedoelde respons beter uitvoeren. In alle drie de onderzoekslijnen bleken
actiegeoriënteerden alleen beter te presteren dan toestandsgeoriënteerden wanneer de druk hoog
was. Deze observatie suggereert dat actiegeoriënteerden niet onder alle omstandigheden over
grotere mentale capaciteiten beschikken dan toestandsgeoriënteerden.
Om de bevindingen van dit proefschrift theoretisch te integreren formuleer ik in Hoofdstuk 5
het “actualiseringmodel” van actie-controle en omgaan met psychische druk. Het model bouwt
voort op recente neuro-cognitieve theorieën over de regulatie van het werkgeheugen (Braver &
Cohen, 2000; Kuhl, 2000). Eén belangrijke veronderstelling van het actualiseringmodel is dat hoge
druk de neuro-cognitieve verbinding tussen het werkgeheugen en gedragsuitvoerende systemen
verzwakt. Door deze verzwakking wordt de actualisering van informatie in het werkgeheugen
moeilijker zodat irrelevante informatie niet uit het werkgeheugen verwijderd kan worden en
relevante informatie niet voldoende verwerkt kan worden. Als gevolg hiervan nemen de efficiëntie
van het werkgeheugen en de beschikbaarheid van intenties voor de gedragscontrole af. Daarnaast
wordt de activiteit van de neuronale overbrenger dopamine, en daardoor de opwekking van positief
affect, verminderd. Met andere woorden, als het werkgeheugen onder hoge druk niet meer
voldoende geactualiseerd kan worden, neemt het psychologische functioneren op cognitief,
affectief, en gedragsniveau af.
When The Going Gets Tough… 137
Een tweede veronderstelling van het actualiseringmodel is dat actieoriëntatie de
actualisering van het werkgeheugen bevordert. Dit gebeurt waarschijnlijk door de opwekking van
positief affect tijdens hoge psychische druk (zie Koole & Jostmann, 2004). De empirische test van
deze aanname vormt een belangrijke taak voor toekomstig onderzoek naar de gevolgen van hoge
druk. In Hoofdstuk 5 geef ik een aantal suggesties hoe dit gedaan zou kunnen worden. Samengevat
integreert het actualiseringmodel de bevindingen van dit proefschrift met hedendaagse theorieën
over de regulatie van het werkgeheugen, en biedt het een aantal veelbelovende perspectieven voor
toekomstig onderzoek naar psychische druk.

Zusammenfassung
Viele Menschen sind im Beruf, in der Ausbildung und in ihrem sozialen Umfeld hohen
mentalen Belastungen ausgesetzt, etwa dann, wenn viele dringende Angelegenheiten zur gleichen
Zeit erledigt werden müssen. Weil es bei hoher Belastung oft schwierig ist, persönliche Ziele zu
erreichen, stellt sich die Frage, wie Menschen auf eine effektive Weise mit Belastungen umgehen
können. In der vorliegenden Dissertation wird diese Frage aus der Perspektive der
Handlungskontrolltheorie (Kuhl, 1984, 2000) untersucht. Die Handlungskontrolltheorie beschreibt
die mentalen Prozesse, die beim Formen, Festhalten (oder Loslassen) und Ausführen von
Verhaltensabsichten beteiligt sind. Kern dieser Prozesse ist das so genannte Arbeitsgedächtnis, ein
komplexes mentales System, das zum Teil in präfrontalen Gehirnarealen lokalisiert ist.
Während hoher Belastungen wird das Arbeitsgedächtnis fortlaufend in Anspruch
genommen. Bei längerer Inanspruchnahme lässt seine Effektivität oft nach. Da das
Arbeitsgedächtnis eine wichtige Funktion innerhalb der Handlungskontrolle erfüllt, ist zu vermuten,
dass der effektive Umgang mit Belastungen eine starke Handlungskontrolle voraussetzt. In der
vorliegenden Dissertation habe ich daher die Hypothese getestet, dass Menschen, die über eine
starke Handlungskontrolle verfügen (Handlungsorientierte), effektiver mit Belastungen umgehen
können als Menschen, deren Handlungskontrolle schwächer ist (Lageorientierte).
In drei Untersuchungenreihen habe ich hohe oder niedrige Belastungen bei handlungs- und
lageorientierten Probanten experimentell induziert beziehungsweise das Belastungsniveau in deren
Alltagsleben erfasst. Die Effektivität im Umgang mit hohen Belastungen habe ich auf drei
verschiedenen psychologischen Funktionsebenen untersucht: Denken, Fühlen, und Handeln. In
einer ersten Reihe von Untersuchungen zur Abschirmung des Denkens (Kapitel 2) zeigte sich an
Hand der so genannten “Operationsspannenaufgabe” (Studie 2.1) und der “Aufgeschobenen
Absichtssaufgabe” (Studie 2.2), dass die Effizienz des Arbeitsgedächtnis bei Handlungsorientierten
unter hohen Belastungen größer ist als unter niedrigen Belastungen. Bei Lageorientierten
When The Going Gets Tough… 139
beobachtete ich den umgekehrten Effekt, nämlich dass die Effizienz des Arbeitsgedächtnis unter
hohen Belastungen kleiner ist als unter niedrigen Belastungen. In einer zweiten Untersuchungseihe
zur Abschirmung des Fühlens (Kapitel 3) beobachtete ich bei Handlungsorientierten positivere
affektive Reaktionen als bei Lageorientierten, nachdem ich zuvor unterschwellig einen negativen
Affekt induziert hatte (Studie 3.1).
In einer dritten und letzten Reihe von Untersuchungen zur Abschirmung des Handelns
(Kapitel 4) zeigte sich, dass Handlungsorientierte schwierige Verhaltensabsichten bei hoher
Belastung besser ausführen können als Lageorientierte. In einer Reihe so genannter “Stroop-
Farbbenennungsaufgaben” (Studien 4.1 – 4.4) konnten Handlungsorientierte eine dominante, aber
unbeabsichtigte Verhaltensneigung besser unterdrücken, um statttdessen eine beabsichtigte
Handlung auszuführen. In allen drei Untersuchungsreihen war die Leistung Handlungsorientierter
nur bei hoher Belastung besser als die der Lageorientierten. Dieses zeigt, dass Handlungsorientierte
nicht in jeder Situation über größere mentale Fähigkeiten verfügen als Lageorientierte.
Um die Resultate der vorliegenden Dissertation theoretisch zu integrieren, formuliere ich in
Kapitel 5 das “Aktualisierungsmodell” von Handlungskontrolle im Umgang mit hoher Belastung.
Das Modell basiert auf aktuellen neuro-kognitiven Theorien des Arbeitsgedächtnis (Braver &
Cohen, 2000; Kuhl, 2000). Eine Grundannahme des Aktualiserungsmodells ist, dass hohe
Belastungen die neuro-kognitive Verbindung zwischen dem Arbeitsgedächtnis und
verhaltensausführenden Systemen vorübergehend abschwächt. Durch diese Schwächung kann das
Arbeitsgedächtnis nicht mehr ausreichend aktualisert werden, so dass irrelevante Information
aktiviert bleibt, während relevante Information nicht ausreichend verarbeitet werden kann. Als
Folge hiervon nehmen die Effizienz des Arbeitsgedächtnis und damit der Einfluss von Absichten
auf die Verhaltenssteuerung ab. Eine weitere Folge ist, dass sich die Aktivität des neuronalen
Botenstoffs Dopamin und damit die Generierung positiven Affekts verringert. Mit anderen Worten,
When The Going Gets Tough… 140
wenn das Arbeitsgedächtnis unter hohen Belastungen nicht mehr ausreichend aktualisiert werden
kann, hat dies die Beeinträchtigung des Denkens, Fühlens, und Handelns zur Folge.
Eine weitere Grundannahme des Aktualisierungsmodells ist, dass Handlungsorientierung die
Aktualisierung des Arbeitsgedächtnis erleichtert. Dies geschieht wahrscheinlich durch die
Generierung positiven Affekts bei Handlungsorientierten als Reaktion auf hohe Belastungen (siehe
Koole & Jostmann, 2004). Der empirische Test dieser Annahme ist eine wichtige Aufgabe für die
weitere Erforschung der Folgen hoher Belastungen. In Kapitel 5 unterbreite ich eine Reihe von
Vorschlägen, wie dieser Test erbracht werden kann. Zusammengefasst lässt sich sagen, dass das
Aktualisierungsmodell es ermöglicht, die vorliegenden Ergebnisse mit aktuellen Theorien des
Arbeitsgedächtnisses zu integrieren, und sich daraus vielversprechende Perspektiven für die
zukünftige Erforschung mentaler Belastungen ergeben.
