Keywo ds: He ping Prosocia behavior Positive afect We -being Prosocia spending

Numerous theories attempt to exp ain humans' extraordinary prosocia ity, but predictions are rare y tested among antisocia individua s, whose dampened concern for others ofers a particu ar y strong test of genera -izabi ity for prosocia action. To bui d upon past research demonstrating the emotiona benefts of prosocia ity among non-ofending popu ations and broaden our understanding of how far this re ationship may extend, we examined whether the emotiona benefts of prosocia spending are detectab e in samp es of de inquent youth and recent crimina ofenders reporting e evated antisocia tendencies and psychopathic persona ity features. Findings revea that, contro ing for base ine happiness, ex-ofenders (N = 501) report greater positive afect after reca ing a time they spent money on others than after reca ing a time they spent money on themse ves. Simi ar y, de inquent youth (N = 64) and ex-ofenders (N = 777) random y assigned to purchase an item for a needy chi d reported greater positive afect than those who purchased an item for themse ves. Fina y, a arge pre-registered rep ication (N = 1295) suggests the immediate emotiona benefts of prosocia spending are de-tectab e among ex-ofenders when contro ing for base ine happiness. Together, these fndings demonstrate the emotiona rewards of reca ed and immediate acts of giving in a new and theoretica y re evant popu ation.

Humans are considered one of the most prosocia species on the p anet and recent research suggests that most peop e fee good after he ping others (Aknin, Barrington-Leigh et a ., 2013). Yet, examp es of se fsh and antisocia behavior abound. Peop e frequent y hurt others by ying, stea ing, and cheating – often to promote se f-interest. In addi-tion, a substantia portion of extreme ofenses, such as rape and assau t, are committed by individua s reporting e evated eve s of antisocia and psychopathic features (Hemphi , Temp eman, Wong, & Hare, 1998). Whi e antisocia actors may be ess ike y to e ective y engage in gen-erous action, is it possib e that they sti reap hedonic benefts from giving? The present investigation exp ores this question by examining the emotiona impact of prosocia behavior in two re evant popu ations – recent crimina ofenders and de inquent youth reporting e evated antisocia tendencies.

Severa ines of evidence suggest that antisocia y inc ined in-dividua s, ike ex-ofenders, may not experience the warm g ow of giving. By defnition, these individua s have committed vio ent or otherwise antisocia crimes that have caused physica , emotiona , or psycho ogica pain to others. Antisocia features are common y asso-ciated with increased se fshness, narcissism, impu sivity, and disregard for others (Hastings, Zahn-Wax er, Robinson, Usher, & Bridges, 2000; Lynam, 2011), which may be why individua s disp aying these

tendencies are more ike y to engage in harmfu and mora y re-prehensib e action than the genera popu ation. Given that many forms of prosocia ity require persona cost and are motivated by care for others (Eisenberg & Mi er, 1987), individua s with a crimina history reporting e evated antisocia or psychopathic persona ity features may experience dampened emotiona rewards or even emotional costs from prosocia action. Indeed, to the extent that reduced empathy and pro-socia emotions are experienced among individua s disp aying e evated antisocia and psychopathic tendencies – features often detected in this popu ation and uti ized for assessment (APA, 2013; Dadds et a ., 2009) – it is possib e that prosocia behavior cou d ead to ower eve s of we -being among this target popu ation, especia y in comparison to beha-vior that provides persona gain and may fu f se fsh drives. This possibi ity is supported by recent corre ationa evidence indicating that the emotiona rewards of generous spending are moderated by se f-transcendent va ues (concern for peop e or entities outside onese f) among non-ofending popu ations; on y individua s reporting higher se f-transcendent va ues reported happiness gains from spending money on others (Hi & Howe , 2014).

(Aknin, Dunn, Sandstrom, & Norton, 2013; Norenzayan & Heine, 2005). Prosocia behavior emerges ear y in ife (Browne , 2013), activates p easure centers of the brain (e.g., Harbaugh, Mayr, & Burghart, 2007), and can be earned at speeds akin to other rewarding activities, such as fnding food rewards (Barta , Decety, & Mason, 2011). Vo unteering and prosocia spending (using one's fnancia resources for others) have been inked with greater we -being in numerous countries around the wor d (e.g., He iwe , Huang, & Wang, 2017; Meier & Stutzer, 2008). Fina y, experimenta evidence indicates that chi dren and adu ts from rich and poor countries express greater happiness after using their re-sources (money or food) to beneft others than after using resources to he p themse ves (Aknin, Broesch, Ham in, & Van de Vondervoot, 2015; Aknin, Dunn, Sandstrom, & Norton, 2013; Geenen, Hohe üchter, Langho f, & Wa ther, 2014). Indeed, a recent meta-ana ysis of 27 ex-perimenta studies suggests that various forms of he ping behaviour have a causa impact on happiness (Curry et a ., 2018). Together, these fndings suggest that the hedonic rewards of prosocia behavior are widespread and raise the possibi ity that they may a so be detectab e within un ike y samp es, such as among ex-ofenders and at-risk or de inquent youth expressing e evated antisocia persona ity features.

Important y, however, the emotiona rewards of prosocia ity may not be comparab e in size across samp es. Indeed, Norenzayan and Heine's (2005) discussion of psycho ogica universa s acknow edges various eve s of commona ity, and identifes one type – ca ed “func-tiona universa s” – that are present in most humans but vary in strength or degree. For examp e, existing research demonstrates that the within-country association between income and happiness fuc-tuates with a country's average income (e.g., Deaton, 2008; Diener & Biswas-Diener, 2002). A ong simi ar ines, the emotiona rewards of prosocia behavior may vary as a function of the actor's antisocia persona ity traits. As indicated in Tab e 1, past experiments probing the we -being benefts of generous as opposed to se f-directed spending in non-ofending student and community samp es typica y revea efect sizes ranging from 0.19 to 0.93. Might the we -being benefts of pro-socia spending be detectab e among antisocia popu ations?

1. Prese t research

The present work seeks to examine whether the emotiona benefts of prosocia ity are detectab e (even if sma ) among antisocia in-dividua s who p ace reduced concern on the we fare of others. In doing so we provide what Popper (1963) termed a “severe test” of the hy-pothesis that prosocia behaviour is a functiona universa and eads to emotiona rewards in most humans by investigating whether giving resu ts in happiness among a high y improbab e popu ation: antisocia actors.

To exp ore this question, we adapted previous paradigms used to compare the emotiona consequences of prosocia and persona y ben-efcia behavior with fe ony- eve ex-ofenders (Experiments 1, 3–4) and high-risk or de inquent youth (Experiment 2). Participants were

Table 1 Observed efect sizes in prosocia spending experiments.

random y assigned to either reca (Experiment 1) or engage in (Experiments 2–4) an act of generous or persona spending and then report their we -being. Consistent with past research (Aknin, Barrington-Leigh et a ., 2013; Dunn et a ., 2008), we predicted that generous action wou d ead to greater positive emotion than persona gain when contro ing for base ine happiness. Respondents a so com-p eted measures of antisocia and psychopathic persona ity traits, a - owing us to confrm that the samp es reported e evated eve s of an-tisocia and psychopathic persona ity features in comparison to community samp es. We report a conditions/manipu ations, measures, and exc usions for a experiments. Materia s, data, and the pre-regis-tration for Experiment 4 can be found at https://osf.io/x3ypv/.

2. Experime t 1

2.1. Methods

2.1.1. Pa ticipants 514 ex-ofenders (Mage = 31.24, SD = 8.06, 0.95CI [30.05–31.90];

67.2% men) were recruited on Amazon's Mechanica Turk (MTurk). Samp e size was determined before any data ana ysis. Participants identifed as Caucasian (66.5%), Asian (11.4%), B ack/African American (9.6%), Hispanic/Latino (9.0%), and American Indian/ A askan Native (1.6%), Other (1.6%). An additiona 2 participants (0.4%) did not respond.

Whi e MTurk has its imitations (e.g., Pao acci & Chand er, 2014), we intentiona y uti ized this p atform to reach a arge number of ex-ofenders. Given that individua s with severe crimina histories as we and antisocia traits may have troub e fnding traditiona work, we reasoned that individua s wou d turn to a ternative options, ike MTurk, that require no background check. This samp e size was determined a priori using G*power to a ow detection of a sma -to-medium efect (d = 0.25) with a pha at 0.05 and 80% power.

2.1.2. Qualifcation and c iminal histo y check Participants indicated whether they had committed a fe ony eve

ofense or engaged in extensive crimina /i ega activity within the past 5 years; on y those reporting a severe crimina history qua ifed (see Tab e 2 for crimina behavior categories and ofense frequencies). Consistent with forensic psycho ogy and crimino ogy methodo ogy (Thornberry & Krohn, 2000), se f-reported crimina behavior was used because we did not have access to federa or state incarceration records. This strategy is advantageous because se f-report data are more in-c usive than federa or state records, which on y refect crimes known to the po ice and drastica y underestimate actua ofense rates (Co eman & Moynihan, 1996). Se f-report measures a so demonstrate favourab e measurement properties (e.g. high re iabi ity; Jo ife et a ., 2003) and are robust to misreporting (Sweeten, 2012).

Average CAPP responses cou d not be com-pared to community samp es because this information is not avai ab e in the iterature. Crimes sum to > 501 because severa participants reported engaging in more than one behavior.

2.1.3. C iminal histo y check Recognizing that se f-reported crimina history may raise concerns

of fa se responding, we imp emented a procedure to identify those that may be ying. Specifca y, we required that participants indicate their crimina activity at both the beginning and end of the survey. In ight of the ong experimenta procedure (100+ questions, taking > 30 min to comp ete) we reasoned that participants who may have ied about their crimina history at the start of the survey wou d not be ab e to accu-rate y report the same activity at the end. Therefore, we compared crimina activities isted at both time points to confrm matched reports. As noted in Tab e 3, responses from thirteen individua s did not match and were exc uded from ana yses, eaving the fna samp e of 501 participants (Mage = 31.21, SD = 8.08, 0.95CI [30.50–31.90]; 67.3% men).

2.2. P ocedu e

Participants comp eted a state (“Do you fee happy right now? 1-not at all, 5-ext emely) and trait measure of happiness (“In genera , I con-sider myse f…” 1-a ve y happy pe son, 7-a ve y unhappy pe son; Lyubomirsky & Lepper, 1999). Consistent with past research (Aknin, Barrington-Leigh et a ., 2013), these items were signifcant y corre ated, (499) = 0.36, p < .001, and averaged to create a measure of base ine happiness. Additiona items assessing state a ertness, tiredness, sadness,

Table 3 Samp e size and exc usion information for Experiments 1–4.

and hunger were co ected as we . For transparency, ana yses inc uding the on y other positive afect term (a ertness) in the base ine composite can be found in the SI for a studies (resu ts do not change when a ertness is added to the base ine composite); a other items were in-c uded as distractors to disguise a focus on we -being.

Participants were random y assigned to reca a time when they spent approximate y $20 do ars on either themse ves (pe sonal spending) or someone e se (p osocial spending). Specifca y, participants saw one of two random y assigned prompts asking them to “p ease take the next two minutes to think back to and describe in as much detai as possib e the ast time you spent approximate y $20 on yourse f [someone e se].” Participants then reported their we -being using the Positive and Negative Afect Schedu e inc uding additiona items “happy” and “sad” (PANAS; Watson, C ark, & Te egen, 1988; PA: α = 0.92; NA: α = 0.93).

We ca cu ated post-reca positive afect by averaging the 10 ori-gina positive afect (PA) items on the Positive and Negative Afect Schedu e (PANAS; Watson et a ., 1988) a ong with ratings of “happy”. We chose to do so in the present work, as done in past research (see Aknin, Dunn, Sandstrom, & Norton, 2013; Aknin, Dunn, Whi ans, Grant, & Norton, 2013; Aknin, Mayraz, & He iwe , 2017; Whi ans, Aknin, Ross, Chen, & Chen, under review) because, whi e the PA sub-sca e of the PANAS captures many e ements of one's current positive state, we reasoned that se f-ratings of one's happiness were extreme y re evant to the question at hand and high y consistent. Supporting this c aim, eva uations of “happy” were high y and signifcant y corre ated with the average of the 10 origina PA items, (499) = 0.724, p < .001. Simi ar y, we averaged the 10 origina negative afect (NA) items on the PANAS with ratings of the word “sad” (ana yses examining negative afect are reported in the SI). Eva uations of “sad” were high y and signifcant y corre ated with the average of the 10 origina NA items, (499) = 0.787, p < .001. Participants a so comp eted the Subjective Happiness Sca e (SHS; Lyubomirsky & Lepper, 1999; α = 0.86) and the Satisfaction with Life Sca e (SWLS; Diener, Emmons, Larsen, & Grifn, 1985; α = 0.91).

To assess antisocia and psychopathic persona ity features, partici-pants then comp eted the Triarchic Psychopathy Measure (TriPM; Patrick, 2010; α = 0.91), the Comprehensive Assessment of Psycho-pathic Persona ity (CAPP; Cooke, Hart, Logan, & Michie, 2004; α = 0.95), and the Psycho ogica Entit ement Sca e (PES; Campbe , Bonacci, She ton, Ex ine, & Bushman, 2004; α = 0.76). Participants a so comp eted the Ba anced Inventory of Desirab e Responding (BIDR; Pau hus, 1984; α = 0.83) to capture impression management and se f-deceptive enhancement (see OSF for study materia s and data; see SI for ana yses demonstrating a sma but signifcant corre ation between psycho ogica entit ement and crimina behaviour).

2.2.1. Coding To gain insight into how ex-ofenders spend money, each reco ec-

tion was coded a ong six dimensions: (i) benefciary (who was the target of spending? e.g. se f, friend, etc.; each target coded as 1 = yes, or 0 = no), and (ii) content (what was purchased? food, c othing, etc.; each item coded as 1 = present, or 0 = absent). In addition, coders rated the extent to which the purchase appeared to be motivated by (iii) need vs. want, (iv) ob igation vs. vo ition, and (v) se fshness vs.

ofense and severa committed crimes of the highest severity (e.g., rape, murder). Moreover, because non-c inica measures of psychopathy do not have cut-of scores to c assify respondents, we compared the re-sponses provided by the present samp e to base rates observed in the genera popu ation; doing so provides a meaningfu benchmark, probing whether the present samp e reported simi ar or e evated eve s of psychopathic tendencies. As a who e, participants reported sig-nifcant y higher scores on the TriPM and two re evant sub-sca es (meanness and disinhibition; Mtotal = 133.30, SD = 22.96, 0.95CI [131.00–135.00]; MMeanness = 38.28, SD = 11.89, 0.95CI [37.20–39.30]; MDisinhibition = 45.85, SD = 12.16, 0.95CI [44.80–46.90]) than community samp es (Dris ane et a ., 2014: Mtotal = 120.10, SD = 15.67, 0.95CI [119.00–121.00]; MMeanness = 32.19, SD = 7.87, 0.95CI [31.60–32.80]; MDisinhibition = 35.13, SD = 7.44, 0.95CI [34.50–35.70]; TriPM tota , t (500) = 12.873, p < .001; Meanness, t(500) = 11.459, p < .001, Disinhibition, t(500) = 19.730, p < .001; see Tab e 2). These fndings suggest that we successfu y recruited individua s with e evated anti-socia and psychopathic persona ity features as compared to the genera pub ic.

2.3.2. Manipulation check Independent samp es t-tests comparing the benefciary identifed in

spending reco ections acted as a manipu ation check, confrming that participants reca ed spending memories consistent with their assigned prompt. Participants in prosocia spending condition were more ike y to indicate that the benefciary was a friend, fami y member, romantic partner or charity. Participants in the persona spending condition were more ike y to indicate that they were the benefciary of their purchase (see Tab e 4).

2.3.3. Emotional consequences of ecalled pe sonal o p osocial spending We compared average post-reco ection positive afect provided by

participants in the two reco ection conditions with an independent samp es t-test. A sensitivity power ana ysis conducted through G*Power 3 suggested we had 80% power to detect an efect of d = 0.22 or

Note: The APSD refers to the Antisocia Process Screening Device and the ICU refers to the Inventory of Ca ous-Unemotiona Traits; both questionnaires as-sess antisocia persona ity features and ca ousness/unemotiona ity in youth under 18. Two separate one-samp e t-tests revea ed that average APSD and ICU tota scores were not signifcant y diferent than scores reported by other justice invo ved youth in previous research (Di ard, Sa ekin, Barker, & Grimes, 2013; Kimonis, Kennea y, & Gou ter, 2016).

simi ar. Resu ts revea ed a margina diference; participants in the prosocia spending condition reported s ight y higher positive afect (M = 3.19, SD = 0.91, 0.95CI [3.08–3.30]) than participants in the persona spending condition (M = 3.05, SD = 0.91, 0.95CI [2.94–3.16]), t(498) = 1.711, p = .088, 0.95CI [−0.021, 0.299], d = 0.16 (Fig. 1). When base ine happiness was added as a covariate to contro for individua diferences in we -being, the main efect of condition on post-reca positive afect was signifcant, F (1,497) = 4.104, p = .043, η2 = 0.01. Important y, the main efect of condition remained signifcant when contro ing for impression man-agement and se f-deceptive enhancement, F(1,493) = 3.914, p = .048, suggesting that positive impression and ego enhancement were un ike y to account for the observed efect. Consistent with past research (Aknin, Barrington-Leigh et a ., 2013), reca ing a prosocia act did not predict higher trait happiness as captured on the post-manipu ation measure of the SHS, t(498) = 0.072, p = .943, or ife satisfaction as captured on the SWLS, t(499) = 0.363, p = .716. However, bootstrap ana yses suggested an indirect efect of condition via positive afect on trait happiness (unstandardized indirect efect = 0.02, 95% CI [ < 0.01, 0.05]) and ife satisfaction (unstandardized indirect efect = 0.03, 95% CI [ < 0.01, 0.06]) when contro ing for base ine happiness.

Coder ratings revea ed that purchase content was simi ar across conditions with a few exceptions (e.g., experiences more common in prosocia condition). Given past research demonstrating that experi-entia purchases ead to greater happiness than materia purchases (Van Boven & Gi ovich, 2003), we added coder ratings of this dimension to the ANCOVA described ear ier. The efect of reca condition on positive afect remained signifcant, F(1,457) = 5.624, p = .018, suggesting that the materia -experientia nature of purchases does not account for the present resu ts. Simi ar y, the efect of condition remained signifcant when contro ing for vo ition (vs. ob igation) and want (vs. need) in separate ANCOVA ana yses, Fs ≥ 4.50, ps < .035, suggesting that the observed efect is robust to variations a ong these dimensions.

Fina y, a though exp oratory, coder ratings indicated that in-dividua s in the prosocia (vs. persona ) spending condition were more

ike y to spontaneous y report being “happy” in their open-ended de-scriptions, F(1,460) = 5.428, p = .020.

Experiment 1 suggests that ex-ofenders experience greater hedonic rewards after refecting upon generous spending than persona spending when contro ing for base ine we -being. We next examined the immediate emotiona consequences of persona and prosocia spending in three experiments.

3. Experime t 2

3.1. Methods

3.1.1. Pa ticipants Seventy-six de inquent youth (Mage = 15.73, SD = 1.33, 0.95CI

[15.40–16.00]; 36.6% men) were recruited at outreach centers pro-viding services for at-risk youth to participate in a study on resi iency and everyday experiences in exchange for gift cards. Participants identifed as Indigenous (15.6%), Caucasian (14.1%), and East Indian (6.3%). Twenty youth (31.3%) indicated that they preferred not to report their ethnicity and another twenty youth (31.3%) did not pro-vide a response. As in Experiment 1, a power ana ysis was conducted using G*Power 3 to determine sensitivity, resu ts suggested we had 80% power to detect an efect of d = 0.65 or simi ar.

If a youth expressed interest, a researcher co ected his/her parent or ega guardian's contact information and gave the youth an in-formationa packet to take home. Parents/guardians were contacted to obtain parenta consent. Once obtained, a researcher set up a one-on-one meeting for data co ection at a oca resource center. Youth pro-vided assent. As noted in Tab e 3, twe ve youth were exc uded for ei-ther: opting-out of the prosocia task (n = 8; this decision is consistent with Aknin, Barrington-Leigh et a ., 2013 and fndings do not change if these individua s are inc uded), fai ing to comp ete > 75% of the de-pendent variab es (n = 2), or because they cou d not understand the study procedures, requiring ear y study termination (n = 2). This eft a fna samp e of 64 high-risk youth (Mage = 15.89, SD = 1.25, 0.95CI [15.60–16.20]; 38.1% men), which surpassed our pre-determined stopping ru e of n = 60 (the sma est number of participants required to detect a medium-to- arge efect as observed in past work, Aknin, Dunn, Sandstrom, & Norton, 2013). Samp e size was determined before any data ana ysis.

3.1.2. Qualifcation To qua ify, youth must have se f-reported either (a) engagement in

one or more of 21 possib e crimina behaviors within the past six months, (b) use of one or more i ega substances in the previous 30 days, or (c) membership in a de inquent peer group, defned as having 1 or more friends engaging in crimina behavior within the past 6 months. No youth were inc uded for meeting criteria “b” on y (see Tab e 5 for the samp e's risk criteria). Inc usion criteria were in-tentiona y broad – though sti designed to identify youth at risk of crimina ity based on we -supported risk factors – to obtain as arge a samp e as possib e.

3.2. P ocedu e

Base ine emotion was assessed using the same items as Experiment 1. State and trait happiness scores were positive y corre ated, (62) = 0.52, p < .001, and combined to create a sing e measure of base ine we -being.

3.2.1. Goody-Bag Pa adigm Adapting a previous paradigm used by Aknin, Barrington-Leigh

et a . (2013), participants were provided with a questionnaire in-forming them that they had earned an additiona $2.50 for their par-ticipation. Funds were represented as a paper voucher. Participants signed a receipt to encourage fee ings of ownership. The questionnaire

5

K.B. Hanniball et al.

then invited participants to use their voucher to purchase a goody-bag (va ued at $3.00) f ed with either choco ate, juice, or both. Critica y, youth were random y assigned to one of two spending conditions. In the pe sonal spending condition, participants were to d the goody-bag they purchased was for them and avai ab e for pickup at the conc usion of the experiment. In the p osocial spending condition, participants were to d that the goody-bag they purchased wou d be donated to a sick chi d at a oca chi dren's hospita . After the purchase, participants received a thank-you note confrming this information.

3.2.2. Opt-out In ight of past research demonstrating that a sense of vo ition is

essentia for experiencing the emotiona rewards of prosocia behavior (Weinstein & Ryan, 2010), participants in both conditions had the op-portunity to opt-out of purchasing a goody-bag and take the cash va ue ($2.50) for themse ves. This option was inc uded to ensure that parti-cipants in the prosocia spending condition fe t as though they had chosen to give a charitab e gift. We attempted to discourage opting-out by exp aining that va ue wou d be mai ed 90 days after study comp e-tion, but eight participants in the prosocia spending condition and nine participants in the persona spending condition opted out of purchasing a goody-bag. As noted in Tab e 3, individua s assigned to the prosocia spending condition and choosing to take the cash for themse ves were exc uded from ana yses because they did not comp ete a prosocia act. This data ana ytic decision is consistent with past work uti izing this paradigm (e.g. Aknin, Barrington-Leigh et a ., 2013) and is necessary to ensure that participant behavior a igned with the manipu ation. Im-portant y, however, resu ts do not change if prosocia opt-outs are in-c uded. Participants opting out of the prosocia spending task did not difer from the rest of the samp e in base ine happiness or any at-risk criteria (e.g., crimina behaviors, antisocia persona ity features; ts < 0.80, ps > 0.30, ds < 0.30), suggesting that these were not the most antisocia or crimina y inc ined individua s. Consistent with past re-search (Aknin, Barrington-Leigh et a ., 2013), the nine participants in the persona spending condition who took the cash were retained be-cause these individua s chose a persona beneft, which is consistent with their condition assignment; resu ts do not change if these nine individua s are exc uded.

Participants noted their spending choice on a purchase card and handed it, with the $2.50 voucher, to the researcher. If the participant purchased a goody-bag, the researcher packaged their items im-mediate y to show that their goody-bag was rea . In both spending conditions, the goody-bag was set-aside unti the conc usion of the experiment and participants were given a pre-prepared note thanking them for their purchase. If the participant took the cash for him/herse f, they were asked to provide their mai ing information for de ivery.

A information indicating condition assignment was unknown to the researcher, prec uding diferentia treatment. This was achieved by: (1) having study materia s organized weeks in advance by researchers who did not run experimenta sessions, (2) ensuring materia s were in sea ed enve opes unti the experimenta session began so that the re-searcher cou d not view condition assignment information, (3) making sure a study materia s were identica for both conditions. As such, the researcher earned of condition assignment at the end of the experiment to give participants in the persona spending condition their goody-bag. Goody-bags purchased in the prosocia condition were donated to a oca chi dren's charity.

After the purchase, participants comp eted the PANAS inc uding “happy” (Watson et a ., 1988; PA: α = 0.83; NA: α = 0.91) and SWLS (Diener et a ., 1985; α = 0.83). The corre ation between “happy” and the 10 origina positive afect items was signifcant and positive, (62) = 0.510, p < .001. Due to a methodo ogica oversight, “sad” was not inc uded in the PANAS.

3.2.3. Risk C ite ia and Delinquent Behavio Youth comp eted the Youth Se f-report of Ofending sca e (Huizinga,

Journal of Experimental Social Psychology xxx (xxxx) xxx–xxx

Esbensen, & Weiher, 1991; α = 0.90), an adapted Teen Confict Survey (Bosworth & Espe age, 1995; α = 0.84), and De inquent Peers Sca e (Thornberry, Lizotte, Krohn, Farnworth, & Jang, 1994; α = 0.94) to assess se f-reported substance abuse within the past 30 days and the proportion of a youth's friend group invo ved in crimina or de inquent behaviors, respective y.

3.2.4. Antisocial pe sonality and callous-unemotional t aits Two questionnaires assessed antisocia persona ity features and

ca ousness/unemotiona ity, precursors of psychopathic persona ity disturbance, in youth under 18: the Antisocia Process Screening Device – Se f Report (Frick & Hare, 2001; α = 0.77) and the Inventory of Ca ous-Unemotiona Traits (Frick, 2004; α = 0.78). See OSF for study materia s and data.

3.3. Results

Most youth (79.7%) reported recent crimina activity and 12% had been incarcerated (see Tab e 5 for more detai ). Additiona y, one-samp e t-tests revea ed that youth in the present study reported simi ar eve s of antisocia persona ity features (MAPSD = 13.10, SD = 5.31, 0.95CI [11.80–14.40]; MICU = 26.14, SD = 8.47, 0.95CI [24.10–28.20]) to other justice-invo ved youth assessed in previous research (Di ard et a ., 2013: MAPSD = 13.82, SD = 5.14, 0.95CI [13.30–14.30] Kimonis, Kennea y & Gou ter: MICU = 24.54, SD = 9.23, 0.95CI [23.30–25.70]; APSD, t(58) = −1.04, p = .30; ICU, t (55) = 1.42, p = .16), suggesting that we were successfu in recruiting an antisocia youth samp e.

Were the emotiona benefts of prosocia spending detectab e among at-risk and de inquent youth? Participants random y assigned to the prosocia spending condition reported higher positive afect (M = 3.16, SD = 0.65, 0.95CI [2.93–3.40]) than youth random y assigned to the persona spending condition (M = 2.75, SD = 0.71, 0.95CI [2.55–3.00]), t(62) = 2.410, p = .019, 95CI [0.069, 0.749], d = 0.60. Resu ts were simi ar when base ine happiness was added as a covariate, F(1,60) = 7.411, p = .008, ηP

2 = 0.11. Post-spending ife satisfaction did not difer by condition, t(61) = 0.777, p = .440, but rep icating Experiment 1 and past research, bootstrap ana yses revea ed that gen-erous spending predicted higher ife satisfaction through positive afect, unstandardized indirect efect = 0.09, 95% CI [0.01, 0.23].

Experiment 2 suggests that the immediate benefts of generous be-havior are detectab e among at-risk youth. Given the sma samp e and restricted age range, we conducted a rep ication with a arger samp e of adu t ex-ofenders.

4. Experime t 3

4.1. Methods

4.1.1. Pa ticipants 848 individua s (Mage = 31.20, SD = 7.25, 95CI [30.70–31.70];

68.0% men) with a se f-reported history of serious crimina activity were recruited on MTurk. Participants identifed as Caucasian (57.1%), Asian (23.4%), B ack/African American (8.9%), Hispanic/Latino (5.3%), American Indian/A askan Native (3.0%), and “other” (2.1%). Two additiona participants (0.3%) did not respond to the question.

Mturk was used to recruit ex-ofenders for the same reasons isted in Experiment 1. A samp e of 800 was determined a priori using G*power to a ow detection of a sma efect (d = 0.20) with a pha at 0.05 and 80% power. Samp e size was determined before any data ana ysis. As noted in Tab e 3, a participants passed the crimina history check, however, consistent with Experiment 1 and past research (Aknin, Barrington-Leigh et a ., 2013) seventy-one individua s in the prosocia condition who opted out of comp eting a prosocia action were ex-c uded from ana yses (exp ained be ow; resu ts are simi ar if these in-dividua s are inc uded). This eft a fna samp e of 777 adu ts

(Mage=31.24, SD = 7.39, 95CI [30.70–31.80], 68.4% men) of ex-of-fenders.

4.1.2. C iminal histo y check The same requirements and procedure uti ized in Experiment 1

were repeated here. The on y diference, however, was that participants were asked to report their crimina history on a s ight y revised crimina check ist that a owed us to emp oy a crimina severity sca ing method to generate ofending scores (Kazemian & Le B anc, 2007; Le B anc & Fréchette, 1989). Once again, we required that participants provide matching crimina history reports at the beginning and end of the survey to warrant inc usion. As noted in Tab e 3, a participants met this requirement and were retained in ana yses. Tab e 6 presents the fu ist of fe onies that participants used to identify past crimina behavior, a ong with the number of participants reporting engagement in each activity.

4.2. P ocedu e

Participants reported their base ine we -being on the same mea-sures used in Experiments 1–2 with the addition of a sing e item “proud”. State and trait happiness scores were positive y corre ated, (775) = 0.47, p < .001, and combined to create a sing e measure of base ine we -being. Ana yses inc uding the item “proud” are presented in the SI and do not difer from those reported here.

4.2.1. Goody-Bag Pa adigm We adapted the goody-bag paradigm for an on ine p atform by

te ing participants that they had earned an additiona $0.10 (presented as an e ectronic voucher) for their participation and were encouraged to take ownership of this money by typing their MTurk ID as an e ectronic receipt.

Participants were then given the choice of making a purchase with their additiona funds. To faci itate more meaningfu purchases, parti-cipants were to d that the additiona $0.10 sum wou d be mu tip ied by 10 to provide $1 of purchasing power. As such, participants random y assigned to the p osocial spending condition were given the option to use their funds to make a $1 donation to one of two rea charity projects current y isted on ine through the non-proft organization DonorsChoose.org. One project provided snack items to hungry stu-dents in ow-income neighbourhoods and the other project provided pens to needy students. Participants random y assigned to the pe sonal spending condition were given the option to purchase a snack item or pen (va ued at $1) for themse ves. Thus, purchase options (snacks or pen) and va ue ($1) were equated across conditions.

4.2.2. Opt-out Once again, given past research demonstrating that a sense of vo-

ition is essentia for experiencing the emotiona rewards of prosocia behavior (Weinstein & Ryan, 2010), participants in both conditions had the opportunity to opt-out of the purchasing decision and keep the $0.10. This option ensured that participants in the prosocia condition fe t as though they had chosen to give a charitab e gift. A tota of 168 participants kept the funds (prosocia spending condition, n = 71; persona spending condition, n = 97), but as noted in Tab e 3, on y those in the prosocia spending condition were exc uded from ana yses because they did not comp ete a prosocia act (consistent with Aknin, Barrington-Leigh et a ., 2013). Individua s opting-out of the prosocia condition did not difer from the rest of the samp e in crimina beha-viour, t(75.46) = −1.32, p = .19 or vio ent activity, t(20.98) = −1.82, p = .08, but they did report higher antisocia ity on the TriPM and CAPP (ts > −2.20, ps < .02). Important y, however, when individua s opting-out of the prosocia condition were removed, the remaining samp e sti reported signifcant y higher antisocia and psychopathic persona ity features than those reported in community samp es (ts > 16.6, ps < .01). Moreover, key resu ts remain unchanged when

prosocia opt-outs are inc uded.2 Consistent with past research, parti-cipants who opted to take the cash for themse ves in the persona spending condition were retained because these individua s chose a persona beneft in the form of cash for themse ves.3

Participants were given a thank-you note after their purchase in-dicating that their donation or item wou d be de ivered at the conc u-sion of the experiment. After, participants reported their current efect on the PANAS inc uding “happy” and “sad” (Watson et a ., 1988; PA: α = 0.92; NA: α = .96). As in Experiments 1–2, the item “happy” was added to the PANAS. The corre ation between “happy” and the 10 origina PA items was signifcant and positive, (775) = 0.737, p < .001. Simi ar y, as seen in Experiment 1, the item “sad” was in-c uded in the measure of NA. The corre ation between the item “sad” and the 10 origina NA items was signifcant and positive, (775) = 0.825, p < .001. Participants a so comp eted the Benefcence Satisfaction Sca e (Marte a & Ryan, 2016; α = 0.92) to assess perceived positive impact of one's behavior on others (e.g., “I have been ab e to improve the we fare of other peop e”).

Fina y, participants comp eted the same measures of antisocia / psychopathic persona ity and ca ousness/unemotiona ity used in Experiment 1: the TriPM (Patrick, 2010; α = 0.91), CAPP (Cooke et a ., 2004; α = 0.96), PES (Campbe et a ., 2004; α = 0.91), and BID-R (Pau hus, 1984; α = 0.80). See SI for ana yses demonstrating a sma but signifcant corre ation between psycho ogica entit ement and crimina behaviour.

were not sent the grano a bar or pen they purchased. Instead, partici-pants were credited the $1.00 va ue as a bonus to their mTurk account within 10 days of study c ose. Simi ar y, participants who opted to keep the $0.10 for themse ves had the money credited to their mTurk ac-count within 10 days of study c ose. Donations in the prosocia spending condition were distributed as stated. Critica y, de ayed payment, do-nation, and debriefng were used to ensure that these payment detai s did not a ter participant behavior during data co ection (see OSF for study materia s and data).

4.3. Results

4.3.1. C iminal activity and antisocial pe sonality Near y three quarters of the samp e (72.6%) had been arrested for

crimina behavior (see Tab e 6 for detai ed breakdown of ofenses). Once again, because non-c inica measures of psychopathy do not have cut-of scores to c assify respondents, we compared the responses pro-vided by the present samp e to base rates observed in the genera po-pu ation as a benchmark. Doing so a owed us to examine whether the present samp e reported simi ar or e evated eve s of psychopathic tendencies. Participants reported signifcant y higher scores on the TriPM and two re evant sub-sca es (meanness and disinhibition; Mtotal = 139.82, SD = 21.20, 0.95CI [138.00–141.00]; MMeanness = 38.65, SD = 10.85, 0.95CI [37.90–39.40; MDisinhibition = 49.04, SD = 11.57, 0.95CI [48.20–49.90]) than commu-nity samp es (Dris ane et a ., 2014: Mtotal = 120.10, SD = 15.67, 0.95CI [119.00–121.00] MMeanness = 32.19, SD = 7.87, 0.95CI [31.60–32.80]; MDisinhibition = 35.13, SD = 7.44, 0.95CI [34.50–35.70]; TriPM tota , t (776) = 25.930, p < .001; Meanness, t(776) = 16.600, p < .001, Disinhibition, t(776) = 33.516, p < .001), again suggesting that we were ab e to recruit individua s with e evated eve s of antisocia and psychopathic persona ity features.

4.3.2. Emotional consequences of pe sonal o p osocial spending Ex-ofenders who purchased an item for a needy chi d reported

higher positive afect (M = 3.39, SD = 0.92, 0.95CI [3.18–3.60]) than ex-ofenders who purchased an item for themse ves (M = 3.25, SD = 0.91, 0.95CI [3.07–3.43]), t(775) = 2.055, p = .04, 0.95CI [0.006, 0.263], d = 0.15. Resu ts were simi ar when base ine we -being was added as a covariate, F(1,774) = 4.696, p = .031, ηP

2 = 0.006, and when contro ing for socia y desirab e responding and se f-deceptive enhancement, F(1,773) = 5.097, p = .024, ηP

2 = 0.007. A post-hoc power ana ysis conducted with G*Power 3 suggested we had 80% power to detect an efect of d = 0.20 or simi ar.

Fina y, we conducted an exp oratory investigation into the impact of spending condition on benefcence satisfaction – defned as the sa-tisfaction one fee s from positive y impacting others – as measured by the Benefcence Satisfaction Sca e (Marte a & Ryan, 2016). Resu ts of an independent samp es t-test revea ed that individua s in the prosocia spending condition reported signifcant y higher fee ings of benefcence satisfaction (M = 5.33, SD = 1.26, 0.95CI [5.04–5.62]) than did those in the persona spending condition (M = 3.80, SD = 1.66, 0.95CI [3.47–4.13]), t(764.62) = −14.521, p < .001. Fee ings of benef-cence, in turn, predicted higher eve s of post-spending positive afect, standardized beta = 0.537, p < .001, whi e contro ing for condition assignment, standardized beta = −0.167, p < .001. As such, these fndings are consistent with mediation; higher eve s of positive afect may be partia y exp ained by fee ings of benefcence (unstandardized indirect efect = 0.44, 0.95CI [0.36, 0.54]), but given the ambiguity surrounding mediation ana yses (Fied er, Harris, & Schott, 2018), these fndings shou d be interpreted with caution as on y one possib e ex-p anation.

Experiment 3 suggests that the immediate benefts of generous be-havior are detectab e among se f-reported ex-ofenders when contro - ing for base ine happiness. Fina y, we tested our main directiona hypothesis – that the emotiona benefts of prosocia spending wou d be

detectab e among antisocia individua s (whi e contro ing for base ine happiness) – in a arge, pre-registered rep ication.

5. Experime t 4

5.1. Methods

5.1.1. Pa ticipants 1414 individua s (Mage = 30.34, SD = 7.39, 0.95CI [30.00–30.70];

62.0% men) with a se f-reported history of serious crimina activity were recruited on MTurk. Participants identifed as Caucasian (52.7%), Asian (28.5%), B ack/African American (9.9%), Hispanic/Latino (4.2%), American Indian/A aska Native (2.8%), Hawaiian/Pacifc Is ander (0.2%), and “other” (1.5%). An additiona 0.2% did not iden-tify their ethnicity.

We aimed to recruit a fna samp e of 1280, which was determined a priori using G*power to detect a sma efect (d = 0.15) at 80% power and a pha at 0.05 one-tai ed. Samp e size was determined before any data ana ysis. We oversamp ed s ight y to a ow exc usions that a igned with pre-registered criteria: fai ing the crimina history check and prosocia opt-outs. Consistent with pre-registered exc usion criteria, one hundred nineteen individua s in the prosocia condition who opted out of comp eting a prosocia action were exc uded from ana yses. To confrm crimina history, we emp oyed the same procedure used in Experiments 1 and 3, which required that participants provide matching crimina history reports at the beginning and end of the survey to warrant inc usion. As noted in Tab e 3, a participants met this pre-registered requirement. This eft a fna samp e of 1295 ex-of-fenders (Mage=30.44, SD = 7.33, 0.95CI [29.90–30.70], 61.1% men).

5.2. P ocedu e

The procedure for Experiment 4 was identica to Experiment 3 with the fo owing exceptions. First, a shorter and more stream ined ist of measures was presented to participants. At base ine, on y state happi-ness was measured (same item from Experiments 1–3) to iso ate the impact of momentary diferences in we -being. Post-spending, on y the adapted PANAS, inc uding the items “happy” and “sad” (PA: α = 0.93; NA: α = 0.96), the CAPP (α = 0.91), TriPM (α = 0.90), and BID-R (α = 0.79) were measured. As in Experiments 1–3, “happy” corre ated positive y and signifcant y with the 10 origina PA, (1411) = 0.741, p < .001. Simi ar y, as seen in Experiments 1 and 3, “sad” corre ated positive y and signifcant y with the 10 origina NA items, (1411) = 0.823, p < .001.

Second, in attempt to further encourage spending and disincentivize opt-out behavior, participants were provided with additiona earnings of on y $0.05 (ha f the va ue of Experiment 3), which was mu tip ied by 20, to provide $1 of purchasing power, if used for a spending decision in both the persona and prosocia spending conditions. Fina y, we updated the charitab e giving choices in the prosocia condition to re-fect new and active postings on DonorsChoose.org. Like before, charitab e projects provided snacks or writing supp ies to needy chi -dren, and purchasing options in the persona condition were snack items or writing supp ies (see OSF for pre-registration, study materia s and data).

5.3. Results

5.3.1. C iminal activity and antisocial pe sonality A arge portion of the samp e (69.0%) had been arrested for crimina

behavior (see Tab e 7 for the fu ist of fe onies that participants used to identify past crimina behavior, a ong with the number of participants reporting engagement in each activity). Consistent with our pre-regis-tered samp ing p an, participants reported signifcant y higher scores on the TriPM (Mtotal = 139.53, SD = 21.73, 0.95CI [138.00–141.00]; MMeanness = 41.89, SD = 11.78, 0.95CI [41.20–42.50];

5.3.2. Emotional consequences of pe sonal o p osocial spending We tested our pre-registered hypotheses with the fo owing ana-

yses. First, we compared post-spending positive afect with an in-dependent samp es t-test. Whi e ex-ofenders who purchased an item for a needy chi d reported higher positive afect (M = 3.23, SD = 0.96, 0.95CI [3.15–3.31]) than ex-ofenders who purchased an item for themse ves (M = 3.17, SD = 0.93, 0.95CI [3.10–3.24]), this diference was not statistica y signifcant, t(1289) = 1.091, p = .138 one-tai ed, 95CI [−0.046, 0.161], d = 0.06. However, consistent with our pre-registered hypotheses, the main efect of condition on post-spending positive afect was signifcant when contro ing for base ine happiness, F(1,1228) = 3.500, p = .031, one-tai ed, d = 0.11. Additiona y and consistent with our pre-registered hypotheses, the main efect of con-dition on positive afect was signifcant when contro ing for base ine happiness and socia y desirab e responding, F(1,1287) = 3.590, p = .029 one-tai ed. Resu ts of a sensitivity ana ysis conducted through G*Power 3 suggested we had 80% power to detect an efect of d = 0.16 or simi ar. These fndings suggest that the emotiona rewards of pro-socia spending are detectab e in antisocia samp es when contro ing for base ine we -being.

6. Ge eral discussio

This research is the frst to examine whether the emotiona rewards of generous behavior are detectab e among individua s with crimina histories and antisocia inc inations. Whi e e evated antisocia and psychopathic persona ity features are thought to refect higher se f-in-terest and dampened concern for others (Hastings et a ., 2000; Lynam,

Journal of Experimental Social Psychology xxx (xxxx) xxx–xxx

2011), this work suggests that adu ts and ado escents reporting anti-socia tendencies experience hedonic rewards from giving when con-tro ing for base ine happiness. These fndings provide a severe test of the theory that emotiona beneft is inked to prosocia action and add to recent work suggesting that the emotiona benefts of prosocia be-haviour may be a functiona universa , detectab e across the g obe and ifespan (Aknin et a ., 2015; Aknin, Barrington-Leigh et a ., 2013).

Efect sizes observed in three of the present studies (Experiments 1, 3–4) are sma er than those detected in past research conducted with non-ofender samp es. Whi e the detection of any emotiona beneft from giving among individua s reporting e evated antisocia and psy-chopathic tendencies is consistent with the defnition of a functiona universa (Norenzayan & Heine, 2005), these fndings suggest that the warm g ow of giving may be neg igib e or absent among exceptiona y antisocia ofenders.

Critica y, however, we be ieve that the present fndings are of va ue for at east three reasons. First, as noted in the introduction, ex-ceptiona y antisocia individua s reporting e evated eve s of psycho-pathic persona ity features are known to experience “ imited prosocia emotions” (APA, 2013) and reduced empathy for others (Dadds et a ., 2009). As such, a though we did not have the means to assess c inica eve s of antisocia or psychopathic persona ity features, the present fndings are notab e precise y because they deviate from theoretica predictions indicating that antisocia actors might experience negative emotiona consequences from engaging in prosocia action, especia y in comparison to opportunities for se f-gain. Second, the present resu ts extend our understanding of prosocia ity and its consequences to new, theoretica y re evant, and understudied samp es: ex-ofenders and de- inquent youth expressing heightened antisocia ity. Fina y, seeing as our samp es represented antisocia actors iving in the genera popu a-tion, these fndings suggest that prosocia ity may be rewarding for the majority of antisocia ofenders encountered on a dai y basis.

Severa important imitations warrant discussion. First, our samp e did not inc ude the most extreme antisocia actors, such as those sur-passing c inica diagnostic thresho ds for psychopathic persona ity dis-order/antisocia persona ity disorder, or individua s current y in-carcerated for extensive crimina careers. As noted above, future research shou d examine boundary conditions at extreme y high anti-socia responding. Second, individua s exhibiting e evated psychopathic tendencies may have troub e reporting their own and others emotions (Herpertz et a ., 2001; Li ienfe d, Fow er, & Patrick, 2006). Indeed, whi e participants may have reported e evated positive afect, we cannot confrm that they are interpreting their afect in simi ar ways to non-ofending samp es. However, such emotiona hyporesponsiveness is rare in se f-reported emotion (Gao, Raine, & Schug, 2012) and, if anything, wou d make the present fndings harder to detect.

Perhaps a more re evant concern is that individua s with e evated psychopathic traits tend to engage in deception, a cardina feature of psychopathic persona ity disorder, especia y when given the opportu-nity to appear as a princip ed character (Li ienfe d et a ., 2006). Whi e it is possib e that participants infated ratings of positive afect after prosocia action to appear favourab y, severa features a eviate this concern. First, data co ection in Experiments 1, 3, and 4 was anon-ymous, meaning that on y the participant was aware of his/her beha-vior and emotiona response. Experiment 2 was conducted in person, but research assistants were unaware of condition, reducing the possi-bi ity for immediate praise or reward. Second, participants committing prosocia behavior in Experiments 2–4 did not have contact with their benefciary, and a gifts were donated anonymous y, ru ing-out im-mediate praise and pub ic positive se f-presentation as exp anations for increased positive afect. Third, participants were unaware of other conditions, removing the desire to anchor responses to other-directed spending. Fina y, the emotiona rewards of prosocia behavior remain whi e contro ing for impression management. Thus a though we cannot defnitive y ru e out se f-presentation as an a ternative ex-p anation, these features minimize concerns.

In addition, participants did not incur arge fnancia oses when engaging in prosocia spending. Indeed, acts of persona and prosocia spending cost participants in Experiments 3 and 4 either $0.05 or $0.10, a sum that was then mu tip ied by researchers to provide meaningfu purchasing power. Given that rea wor d acts of persona and prosocia spending are rare y this sma or mu tip ied in va ue, this may imit genera izabi ity. Fina y, statistica power to detect efects in Experiment 2 was ow given the sma samp e and s ow recruitment. Whi e sma samp es may be a common occurrence when studying unique popu ations, future research shou d aim to rep icate these fndings with in-person methods and arger samp es.

The present fndings ofer practica and theoretica imp ications. First, resu ts demonstrating that ex-ofenders and at-risk youth may experience emotiona benefts from he ping others might humanize ex-ofenders who are often viewed as irredeemab e (Pager, 2003). To the extent that emotiona rewards make subsequent behavior more ike y, the present work suggests that a truistic based intervention strategies may provide efective routes for treatment and rehabi itation (Barnao, Ward, & Robertson, 2016; Gredecki & Turner, 2009; Lebe , Richie, & Maruna, 2015), presuming that they are consistent with we -va idated methods of correctiona programming (Andrews, 2012). In turn, these fndings cou d ofer guidance for re-eva uating how crimina and high-risk popu ations are treated, especia y through rehabi itation (Lebe et a ., 2015). More broad y, these fndings contribute to a greater un-derstanding of human prosocia ity and suggest that the warm g ow of giving may be detectab e among antisocia popu ations.
