Vocabulary acquisition: a neglected aspect of language learning.
Paul Meara
Introduction
Vocabulary acquisition is part of the psychology of second language learning that has
received short shrift from applied linguistics, and has been very largely neglected by
recent developments in research. This neglect is all the more striing in that learners
themselves readily admit that they e!perience considerable difficulty "ith vocabulary,and once they have got over the initial stages of acquiring their second language, most
learners identify the acquisition of vocabulary as their greatest single source of
problems.
This article is an attempt to redress this neglect. #t summarises the current "or being
done on vocabulary acquisition, and dra"s attention to a number of studies carried out
by e!perimental psychologists "hich may have implications for the development of
vocabulary in the second language. The article ends "ith a number of questions "hich
have not been investigated in any depth, but "hich seem to me to be "orth looing at
more closely.
A: Bibliographies and general works
$espite the comments above about the general level of neglect in the study of
vocabulary acquisition, there do e!ist a number of bibliographies of relevance to
anybody "oring in this field. The most important of these is $ale and %a&i 19'(, a
very e!tensive "or, not primarily concerned "ith foreign language acquisition, but
containing three relevant subsections "ith some 1)0 references. The 19'( edition of this
"or is actually a re"oring of an earlier edition, and this may account for the fact that
most of the references relate to second language "or carried out in the 19(0s. The most
recent bibliography dealing specifically "ith *+ vocabulary acquisition is T"omey 199.
This "or is patchy in its coverage, ho"ever, and a fuller bibliography, using a largerdatabase, is in preparation -Meara, in prep..
The principal impression that emerges from these bibliographies is that research in
vocabulary acquisition has been largely atheoretical and unsystematic. There are no
1

2/29
Meara 1980
clear theories of vocabulary acquisition, and the level of research activity is in general
fairly lo". T"omey, for instance, contains a large number of references "hich are short
articles aimed at providing practical tips for teachers concerned "ith particular items of
vocabulary for a particular target audience -e.g. /ro"n 19 Martin 19' 2alt 19'%idout 19, and on the "hole, research in the field has avoided the serious theoretical
questions that arise once one moves a"ay from this very basic level.
3 number of generalised approaches to vocabulary acquisition do e!ist. 4alisson 190
discusses vocabulary teaching at length, and considers the effectiveness of different
types of vocabulary learning e!ercises. These ideas are e!panded in 4alisson 199. 3n
approach to vocabulary teaching based on contrasting le!ical structure is to be found in
5olec 19 -cf. also $agut, 19, for a shorter argument on the same lines. T"o other
large6scale "ors, $ale, 7%oure and /amman 191 and 7%oure 19 are also "orth
mentioning at this stage. They are both concerned e!clusively "ith first languagevocabulary development, but the ideas discussed are clearly of some relevance to second
language learners.
The also e!ists a number of shorter articles "hich dra" attention to the need for further
"or on vocabulary acquisition. Marton 19 discusses the problems of idioms, "hich
he sees as the biggest obstacle to fluent comprehension in advance learners. *ord 19
dra"s attention to the importance of *eopolds 198 study of semantic development in a
bilingual child -cf. also oshida 198 for an empirical study along these same lines. 3
brief but e!cellent critique of vocabulary research is *evenston 199, "ho reiterates a
number of points made in this paper, criticising applied linguistics for its general neglect
of vocabulary learning in favour of the study of syntactic development. *evenston
discusses a number of research pro:ects "hich have only recently begun, and "hich are
therefore difficult to assess satisfactorily. These include *evenstons o"n "or, -/lum
and *evenston 198 and *evenston and /lum 19, "here it is argued that the le!ical
simplification strategies used by learners may follo" universal rules and *innarud
199, "ho suggests that foreign language learners may have characteristically lo" levels
of vocabulary richness compared to normal speaers. -7n this use of type toen ratios as
a measure of learners vocabulary cf. also ;ebber 19,

B: Vocabulary control
The best developed and most systematic "or in the field is to be found in attempts to
:ustify the selection of vocabulary items for inclusion in courses and e!aminations on the
basis of frequency counts and similar ob:ective measures. This "or is too "ell6no"nto need discussion here. 4ood summaries can be found in /ongers 19 Macey 19')
and 2yracuse =niversity %esearch >orporation 19(.
$espite their obvious merits, frequency counts are no" very much out of favour "ith
applied linguists -cf. ;ilins, 19+, for a fairly typical criticism of this sort approach. #n
contrast to the very carefully chosen vocabulary of earlier course boos, many modern
boos appeared to rely almost entirely on sub:ective assessments of the usefulness of
"ords. Van ? -19, for instance, contains no discussion of "hat criteria "ere used for
the inclusion of "ords in the Threshold *evel vocabulary -cf. also 5offman 19'. #n
general, language teachers seem to be una"are of more recent developments in "ordcounts. ;estsGeneral Service List19)( is often cited by publishers and e!amining boards
as guiding their choice of "ords in readers and e!aminations for learners in ?nglish, for
e!ample, despite the fact that both this list and the related Thorndie6*orge list have
no" been superseded by the more recent @ucera6Arancis count -@ucera and Arancis
19'. %ecent counts for a number of other languages commonly taught to learners also
e!ist, and ought to be more "idely no"n. These include Builland and >hang6
%odrigue& 19' for 2panish Builland, /rodin and $avido"itch 190 for Arench and
Builland and Traversa 19( for #talian. 3n important feature that differentiates most of
these modern counts from their earlier counterparts is the use of computers in their
preparation. 3ll the early counts "ere carried out by hand -the Thorndie6*orge count
"as in fact begun during the $epression as a "ay of providing "or for the
unemployed, and "ere accordingly both e!pensive and slo" to reach completion. The
rapid processing facilitated by computers maes it possible to produce "ord counts at
minimal cost, and to eep them regularly updated.
This use of computers to carry out simple statistical analyses of te!ts is a development
"hich is liely to be of some importance to language teachers, as it has considerable
implications for the preparation teaching materials. >omputer programs "hich "ill do
"ord counts and similar basic statistics on continuous te!t have e!isted for some time,
and they are no" beginning to appear in the form of easy6to6use pacages, designed for
amateurs "ith no real e!perience of computer programming, and they require onlyminimal instruction before they can be used. 3n e!cellent e!ample of an easy to use
pacage of this sort is the Oxford Concordance Project -5oceyand Marriott 199680
/urnard, 5ocey and Marriott 199. This pacage produces basic "ord counts for te!ts
of any reasonable length, alphabetical listings, frequency listings, concordances "ith
(
8/12/2019 Paul Meara_Vocabulary Acquisition
4/29
Meara 1980
conte!ts of specified lengths, and so forth. Though the pacage is primarily aimed at
literary scholars, its uses are of course not limited to literary te!ts. #t could also be used,
for e!ample, to provide accurate frequency counts of the vocabulary used in special6
purpose situations or to prepare a glossary to accompany set te!t, and so forth. =se oftools of this ind seems liely to become increasingly important in the preparation
teaching materials -cf. *yne and 19) >ulhane 19 and Bohnson 19+. 3n interesting
general introduction to this sort of "or is Morton 199.
This outline of research into vocabulary control and selection has been deliberately brief,
and is not intended to be a comprehensive one. 7n the "hole this "or is "ell6no"n
and reasonably familiar. My main reason for raising it here is because "or of this type
has played such a preponderant part in the study of vocabulary acquisition that no
revie" "ould be complete "ithout at least a cursory mention. 5o"ever, the "or is
also important because it illustrates t"o aspects of research into vocabulary acquisition"hich are characteristic of the field is "hole, and therefore deserve further comment. #n
the first place, this "or is characteristic in that it concentrates on "hat is basically a
problem to do "ith the management of learning, rather than "ith the learning process
itself 6 i.e. the ob:ect of this type of research is to decide "hat "ords are to be taught, not
to find out ho" "ords are actually learned. This is an important point, and "ill be
returned to later at the end of the ne!t section. #n the second place, this "or also
illustrates ho" easy it is to fall into the trap of accepting uncritically a "hole set of
assumptions, and to design a large research programme around these assumptions,
"ithout ever calling their validity into question. #n this case, the central assumption is
that it really is necessary to place a severely restricted upper limit on the number of
"ords that the learners can reasonably be e!pected to acquire in a foreign language.
2ome simple arithmetic indicates that a vocabulary of +000 "ords could be learned in 11
months if ne" "ords "ere acquired at a rate si! per day. This figure does not appear to
be "ildly e!cessive, given "hat "e no" about the capacity of the brain to acquire ne"
information. Cevertheless, most teachers "ould undoubtedly consider +000 "ords to be
"ell beyond the capacity of many learners, even over a five6year course instruction -cf.
for instance, ;iclo" 19, and /arnard 191, "here these assumptions are made quite
e!plicit. Co doubt there is some practical :ustification, based on e!perience, for this
general belief that learners cannot easily acquire a large foreign language vocabulary in
a short space of time, but the theoretical basis for this agreement is by no means clear.
This is obviously an area in "hich further research "ould be most useful.
C. Mnemonics
The second ma:or area of research to be discussed is one "hich has, in a "ay, addressed
itself to this problem, challenging the assumption that massive vocabularies cannot be
8/12/2019 Paul Meara_Vocabulary Acquisition
5/29
Meara 1980
acquired by introducing mnemonic techniques into the teaching of vocabulary.
The best studied of these methods is the ey"ord method "hich has been the ob:ect of
considerable attention in the last fe" years particularly in the =nited 2tates -3tinsonand %augh 19) 3tinson 19) %augh and 3tinson and 19 3/3**7
-pronounced cob6eye6oh DsicE might be lined to ?nglish ?? and ?? to 57%2? via
the image of horse "ith a great side cyclopean eye in the middle of its forehead. 7r
more prosaically, >3/3**7 might be lined to the ?nglish "ord >3/, "hich in turn
"ould be lined to 57%2? via the image of horse dra"ing a cab. The papers listedabove report a number of e!periments "hich compare more traditional "ays of learning
vocabulary -e.g. list repetition "ith this ey"ord method, and despite its initial
implausibility, present some impressive results in support of this sort of practice. %augh
and 3tinson -19, for e!ample, report that learners using the ey"ord method can
cope "ith very long list of "ords -'0 items and still get 80 percent correct on a
subsequent test, a figure that is considerably better than that produced by learners using
repetition and rehearsal methods. More importantly, the ey"ord groups preserve their
advantage over time, and sho" less evidence of forgetting than is found "ith control
groups.
This evidence is very impressive at first sight, but "or of this ind is actually rather
problematical at a deeper level, and needs to be treated "ith some caution. The most
obvious problem is that e!periments of this sort treat vocabulary items as discreet pairs
of translation equivalents, and completely ignore the comple! patterns of meaning
relationships that characterise a proper, fully formed le!icon, as opposed to a mere "ord
list. *earning vocabulary is not :ust a matter of acquiring translation equivalentsF it is
"ell6no"n that languages rarely map their le!ical items onto each other in a one6to6one
fashion. 2ome le!ical structuring must go on even "hen the shortest "ord list is
learned, and any vie" of vocabulary acquisition "hich treats the problem as a simple
matter of pairing "ords "ith their translation equivalents is an oversimplified one,
"hich cannot adequately account for ho" these semantic relationships are built up in aforeign language vocabulary. 3ll the e!perimental studies of vocabulary acquisition
"hich mae use of mnemonic devices are basically subscribing to model of paired
associate learning "hich does not seem to me to be sufficiently rich to account for "hat
is involved in the acquisition of a second language vocabulary -cf. for e!ample >rothers
)
8/12/2019 Paul Meara_Vocabulary Acquisition
6/29
Meara 1980
and 2uppes 19' "here a model of vocabulary acquisition based on paired associate
learning e!plicitly discussed.
3 second problem that characterises the ey"ord studies is that they are generally one6off e!periments that do not study real language learners in the course of learning a
language, but only sub:ects prepared to tae part in a small number of e!perimental
sessions in a laboratory setting. This means that the sub:ects tested often have initial
vocabulary of &ero, and it is unclear ho" far and results in such e!periments might be
generalisable to more advanced learners. More importantly, it means that the
comparison bet"een the ey"ord method and other methods is usually limited in
practice to methods that can also be contained "ithin a single e!perimental session, such
as rote learning by repetition. ;hether the ey"ord method is in the long6term more
effective than other methods "hich are not readily comparable "ith it, such as the 2ilent
;ay, or Total #mmersion, or even methods "hich place special emphasis on vocabularyacquisition such as 4ouins 2eries Technique -4ouin 1880 or /arters >omaparative
Method -/arter 190 /ecer 19, is typically a question "hich is not ased. #ndeed,
even "ithin its o"n terms of reference, the comparisons made are rather spurious. #t is
difficult to imagine that even the most ardent believers in rote learning methods might
require their students to use this method "ith lists containing '0 items. #t seems
important, then, that these laboratory tests should be complemented by properly
controlled longitudinal classroom tests, before their findings are "idely accepted.
3 third problem is that the ey"ord method is used principally in situations "here the
target language "ord is required to evoe the native language equivalent. The phonetic
lin idea seems to "or reasonably "ell in this respect, and the method does seem to
have some value as far as recognition vocabulary is concerned. The value of the method
for developing active vocabulary is much less clear, ho"ever, and it seems liely that the
practice of stressing crude phonetic similarities bet"een *1 "ords and target language
"ords "ould in the long6term have a serious detrimental effect on the pronunciation of
target language "ords.
3 final point to be made about this "or is that %augh and 3tinson, at least, have a
highly directive approach to the choice of ey"ords. 7ne might have e!pected that this
choice could easily be left to the individual learner, but %augh and 3tinson actually go
to some lengths to stress that not all ey"ords are equally effective, and only ey"ordssho"n by e!tensive research to be effective should be used.
3 more recent mnemonic technique is the 5oo ;ord technique, described by
8/12/2019 Paul Meara_Vocabulary Acquisition

Meara 1980
suffer some of the same problems as the ey"ord method. The same criticism also
applies to 7tt, /lae and /utler 19', "ho report a number of studies using elaborative
techniques -*ado, /ald"in and *obo 19' /utler, 7tt and /lae 19( @nop
1914roberg 19+ 5olley 191 cf also 2et&ler and >lar 19'.
. !eneral comments
2o far "e have covered t"o areas of research in the broad field of vocabulary
acquisition. These t"o areas may at first sight appear to be relatively unconnected. #n
fact, ho"ever, they are both lined in that they share common defectF their concern "ith
the peripheral aspects of vocabulary acquisition rather than central ones. #n the case of
research into the uses of frequency counts, "e have already seen ho" the management
of learning rather than an understanding ho" learning taes place and "hat it involves,
is the principal driving force behind the investigations reported. /asically, the learners
load is lightened for them by "oring out beforehand "hich "ords are liely to be ofuse to them, and "hich ones are not "orth the trouble of learning. ;hat happens to the
"ords that are learned is not in question. ;ith mnemonics, too, the emphasis is placed
squarely on the management of the learning process, the main theoretical questions
ased being ones concerned "ith the effectiveness of different forms of presentation.
/oth these approaches, then, are concerned "ith "hat is basically the periphery of
acquiring ne" vocabulary. et it must be obvious that these peripheral aspects,
important though they may be, leave unans"ered a large number of questions "hich
are of considerable relevance to our understanding of ho" vocabulary is acquired.
*earning ne" "ords is not an instantaneous process 6 if it "ere, and if presentation "ere
the only critical variable involved, then "ords "ould not be forgotten and need to be re6
learned. 3s it is, ho"ever, it seems that "ords are absorbed slo"ly over time, and that
only gradually do they become fully integrated into the learners personal stoc of
"ords, "hen they can use them "ith the same sort of fluency and that characterises the
"ords they use in their native language. 2ome "or that is relevant to this rather more
difficult question is discussed in the sections that follo".
There does e!ist a reasonably large body of e!perimental "or "hich has attempted to
investigate ho" bilingual speaers store "ords in their mental dictionaries. These
studies may not appear to be of direct relevance to language teaching and language
learning, but in fact their relevance is often greater then appears at first sight. Theirimportance lies in the fact that they provide us "ith some clues about "hat the end
product of learning a foreign language might consist of, and "hat sort of behaviour can
be e!pected of a fluent bilingual. #nformation of this ind should, in theory at least,
enable us to compare the behaviour of non6fluent bilinguals 6 i.e. language learners 6
8/12/2019 Paul Meara_Vocabulary Acquisition
8/29
Meara 1980
"ith that of fluent bilinguals, and so to mae inferences about the "ay a developing
vocabulary in a second language gro"s. /asically, this "or can provide us "ith a
model, albeit a setchy one, against "hich to assess the more limited abilities of less
fluent learners.
Most of the "or to be described in the ne!t sections is not ostensibly concerned "ith
foreign language learners the sub:ects used in these e!periments are usually balanced
bilinguals 6 i.e. speaers "ho are :udged to be equally fluent in both their languages.
The main purpose of this research has been to compare t"o types of bilinguals 6
compound and coordinate 6 a distinction first dra"n by ?rvin and 7sgood 19). ?rvin
and 7sgood argued that the "ay in "hich a language "as acquired might be e!pected
to produce different types of structuring in a bilinguals mental dictionary. >ompound
bilinguals, those "ho have acquired the t"o languages together in a single environment,
usually in infancy, might be e!pected to have a single set of meanings tagged by t"osets of labels, one for each language. #n contrast, ?rvin and 7sgood argued that
coordinate bilinguals, "ho learned their t"o languages in largely separate
environments, might develop "hat are effectively t"o separate le!icons, one for each
language, "hich function independently of each other.
3gain, this "or may not seem to be directly relevant to second language acquisition,
but the relevance is there, nonetheless. *ambert has argued that certain types of
teaching method may be more liely to produce behaviour characteristic of one type of
bilingual, rather than the other. $irect Method teaching, for instance, "hich tries to
eliminate reference to a learners mother tongue, might be more liely to produce the
learners "ith the characteristics of coordinate bilinguals. ?!perimental evidence to
support this claim is not available, ho"ever, and a rather different claim has been put
for"ard by %iegel 19'8. %iegel argues that this dichotomy is a false one, and that there
is actually a natural development from a sort of compound system to one "hich is closer
in ind to the classical coordinate model, irrespective of the language acquisition
bacground.
The reason "hy this "or is of some relevance to second language acquisition is that
many of the balanced bilinguals the used as sub:ects in these e!periments are actually
far from equally fluent in their t"o languages. #n fact, the criteria used to decide on an
acceptable level of ability in the second language are often ill defined and crude, and inpractice the term bilingual can mean anything from fully and equally fluent in both
languages, to someone "ho has only barely begun to acquire their second language and
could not be considered equally fluent by any stretch of the imagination. The
unsatisfactory nature of the tests used to measure second language fluency -often only
8

Meara 1980
self6ratings, or impressionistic :udgements made by the e!perimenter is a ma:or fla" in
this literature. #t does mean, ho"ever, that a number of the studies, despite their
pretensions, are actually concerned "ith ordinary language learners.
The "or to be considered in the ne!t sections fall into t"o partsF -a e!periments
concerned "ith the general question of "hether the bilinguals le!icons are separate or
independent, and -b e!periments concerned "ith the semantic relationships that e!ist
bet"een "ords in the bilinguals le!icons. 3 third area 6 the ability of bilinguals to
handle "ords in each of their t"o languages in very demanding situations such as
tachistoscopic recognition tass, or dichotic listening tass, and so forth 6 "ill not be
considered here, due to lac of space. #nterested readers are referred to 3lbert and
7bler 199, an e!cellent boo "ith a superb bibliography -though cf. 4reen and
Ce"man 1980 for critical revie". This "or suggests that there may be ma:or
differences bet"een stronger and "eaer languages, and provides some evidence for theclaim that second language "ords may be processed less effectively by certain parts of
the brain. #n particular, a number of studies suggest that there are hemispheric
asymmetries for different languages -cf. ;alters and Gatorre 198 for 2panish 5amers
and *ambert 19 for Arench @ershner and Beng 19+ for >hinese and 7rbach 19)( for
5ebre". This type of research is becoming increasingly sophisticated and influential
and loos lie becoming one of the ma:or gro"th areas in psycholinguistics in the
immediate future.
". Memory e#periments
The "or to be revie"ed in this section consists of a number of e!perimental studies
"hich have all attempted to test the claim that bilinguals have t"o separate,
independently functioning le!icons, rather than a single fully integrated one.
Aor reasons "hich are not "holly clear, this claim seems to have been most often
investigated by the use of memory tass, and in particular by the use of tass "here
interference from one language to another is observed. This is obviously a fairly crude
tool, and the results found in these e!periments are correspondingly limited. The
general line of argument is that if bilinguals t"o sets of "ords "ere stored totally
independently, then very little interference "ould be e!pected in tass that require
sub:ects to use both of their languages. ;here interference is found, this is usually
interpreted as supporting the claim that the t"o languages function interdependently,and are not "holly separated.
The more important studies of this ind are summarised in table 1. =seful discussions
of this "or "ill be found in 3lbert and 7bler 199 and Mc>ormac 19. The e!peri6

mental methods may seem rather obscure, but in general they are techniques "hich
have been "idely used in e!periments "ith monolingual sub:ects, and "hich produce
robust results "hich are reasonably "ell understood.
The bul of the "or reported in table 1 is generally taen as supporting the
interdependence position, rather than the independence positionF i.e. it seems to support
the claim that "ords in a second language are indeed integrated in some "ay "ith
"ords in the first language to form a comple! "hole le!icon. The logic of this argument
is not al"ays as clear as it might be, ho"ever and some of the data argues strongly
against this position. Tulving and >olotla 190 for e!ample sho"ed that in mi!ed
language lists of "ords, recall "as much "orse than in single language lists, and that the
greater part of this deficit seems to be due to the fact that *1 "ords are handled less
satisfactorily in secondary memory than "ords from "eaer languages. This finding is
at odds "ith some of the other findings reported, and is not "hat "ould have beene!pected, but there are no obvious faults "ith this e!periment, and it therefore needs to
be taen seriously. 2ome of the other e!periments, particularly the ones that use
2panish as one of the languages tested, are rather less satisfactory and need to be treated
"ith some caution. The sub:ects in these studies are usually schoolchildren brought up
speaing 2panish as their mother tongue, but being taught ?nglish as the medium of
instruction in 3merican schools. Most of the sub:ects rated themselves as more fluent in
?nglish than in 2panish, and "ere thus classified as ?nglish dominant, but this seems
rather implausible. The use of self6ratings "ith sub:ects such as these seems to be an
unreliable method of assessment in vie" of the obvious pressure that sub:ects must be
under to overrate their competence in ?nglish and to underplay their abilities in
2panish.
4enerally speaing, the results of these studies sho" that sub:ects are a"are of the
language in "hich "ords are presented, and that they use language as a classifying label
more successfully than they use other more arbitrary coding features such as colour, but
this last finding is hardly surprising in vie" of the artificiality and unfamiliarity of the
colour coding tas -cf. Mc>ormac 19'. More interesting is the finding that it is much
harder to remember the language of presentation "hen languages and semantic
categories are confused, and the finding that sub:ects have some difficulty in recognising
"ords in a list as ne" ones "hen they have previously been presented in translated
form. These results sho" clearly than "hen some ind of cognitive operation other thansimple recall of the phonetic form is called for, it does become e!tremely difficult to eep
t"o languages apart. #n this sense, forms in one language clearly evoe the
corresponding related forms in the other language, a finding "hich "ould be very
difficult to e!plain if the independent le!icons claim "ere true.

. -emantic tests
The "or reported in the previous section is rather unsatisfactory in that it all treats the
bilinguals le!icon as though it consisted of one or t"o undifferentiated "holes about
"hich it "as possible to mae s"eeping generalisations. There is, of course, no reasonto assume that all the "ords in the le!icon should behave in the same "ay as each other,
and :ust as "ords are differentiated in the le!icons of monolingual speaers in terms of
frequency, length, and other similar ob:ective characteristics, it is quite liely that similar
features may produce subsets of "ords in the bilinguals mental le!icon "hich also have
quite different behavioural properties.

here. ;hat this "or sho"s, "ithout e!ception, is that interlingual conditions do sho"
strong evidence of interference, though less than "ould be e!pected in the case of
monolingual sub:ects. $yer sho"ed that the level of interference "as in part related to
the phonetic shape of the "ords. Thus, for ?nglish speaer, for e!ample "hen ased toname the "ord printed in red in, the 2panish "ord azul"ould be much less disruptive
than the Arench bleubecause of the similarity bet"een bleuand the ?nglish "ord blue.
7ther things being equal, ho"ever, the amount of interference caused by the foreign
language "ords appears to depend on the level of proficiency of the sub:ects, but this
correspondence has been measured only in very gross terms. 3gain, the logic of these
data is that they support the idea that bilinguals t"o le!icons are integrated into a single
"hole. 5o"ever, if bilinguals colour "ords in a second language "ere totally
integrated "ith their *1 colour "ords, then one "ould e!pect to find 2troop interference
equally great in either language. #n as much as the "eaer language produces less
interference, this suggests that "ords in second language are not fully integrated at thesemantic level, or at least than they are not treated "ith the fluency that is usually
accorded to first language "ords. 3 similar argument based on data using semantic
differentials in t"o languages is to be found in Baobovits and *ambert 19'1 and
*ambert and Baobovits 19'0.
7ne of the most accessible and most easily understood methods of studying the
structure of semantic relationships in bilingual le!icons is the use of "ord associations.
#n its simplest form, this technique involves the presentation of a number of single
"ords to the sub:ects participating, and they are then instructed to reply "ith the first
"ord that each of these stimulus "ords maes them thin of. The bul of the responses
produced in tass of this sort are note"orthy principally for their banality, at least as
long as unemotive, common "ords are used. Aar from being original, most peoples
responses are characteristically shared "ith a large proportion of the rest of the
population of normal adult native speaers -cf.

and there thus e!ist "ell6documented sets of response norms for these 100 "ords,

providing the responses. This "ord list has also been translated into a number of
languages other than ?nglish -%osen&"eig 19'1 for Arench, #talian and 4erman5a"orth 199 for 2panish and this maes it possible to compare the responses of native
?nglish speaing learners of these languages "ith responses that "ould be e!pected of a
normal native speaer population. The principal disadvantage of using the @ent6
%osanoff list is that a large proportion of the "ords that mae it up consist of high
frequency "ords "hich produce highly stereotyped response patterns "hich do not
vary greatly from one language to another. This means that only a small subset of the
list is of any real interest "here the main purpose of the study is to mae cross language
comparisons.
-b method. The standard "ord association method has already been described. 3number of variations on this basic theme "ill be found in table +, ho"ever. The chief of
these is the continuous association method in "hich a single "ord is presented as the
stimulus but instead of providing only a single "ord in response, sub:ects are required
to produce a continuous stream of responses for a given length of time -usually in the
region of one minute. These responses are then pooled and counted as in the standard

measure. This technique produces patterns of responses that closely resemble those
produced "ith the standard method using single responses. The continuous association
method has the practical advantage that it is viable "ith a relatively small number of
sub:ects, ho"ever. $eese 19') claims that a minimum of )0 sub:ects is necessary toproduce stable norms for ?nglish using the standard method, and there is some
evidence that other languages may require even larger numbers of sub:ects than this.
;ith the continuous association method, ho"ever, stable response patterns can be
found "ith as fe" as 1) sub:ects.
-c interlingual associations. These are associations made in a language that is not the
same as the one in "hich the stimulus "ord "as presented.
-drestricted associations. This term describes a technique principally used by %iegel and
his associates. #t consists of a basic elicitation technique for single responses, but "ithlimitations imposed on the type of response allo"ed. Thus, for e!ample, sub:ects might
be instructed to produce a response that could describe the stimulus, or one that "as a
superordinate of it.
-e language s"itching. This variation is used only in con:unction "ith the continuous
association method. 2ub:ects are required at specified intervals to stop producing
associations in one language, and to change to their other one.
$espite these important differences in method, it is possible to dra" some general
conclusions from the studies of "ord association behaviour in bilinguals and foreign
language learners. Airstly, on measures of fluency, such as number of responses, speed
of responses and so forth, bilingualspeaers are less adept in their "eaer language than
in their stronger one. 2econdly, responses in a "eaer language tend to be striingly
lessstereotyped than responses in a stronger language. This finding is odd in vie" of
the fact that learners must have smaller vocabularies than native speaers, and this
"ould lead one to e!pect that the range of possible responses "ould be correspondingly
more restricted and less variable. The general inference from these t"o points is that
"ords in a second language are less "ell6organised and less easily accessible than those
in the mental le!icon of native speaer. 5o"ever there is some evidence that these
differences diminish "ith increasing proficiency in the second language, and this
suggests that given the right sort of coa!ing, "ords from the second language do end upby becoming fully integrated into learners personal le!icons.
Thirdly, clang associates -i.e. responses "hich are principally phonetically motivated,
rather than semantically motivated account for a large proportion of the responses

in foreign language learners. 5o"ever, even this "or is unsystematic, and fails to
sho" any signs of a coherent and coordinated research strategy. This "or also suffers
from the dra"bac that it is concerned principally "ith groups of learners in an area
"here large individual differences might be e!pected.
>learly, then, the study of vocabulary acquisition is an area "here the sort of research
"or out that has been carried out is far from satisfactory, and "here a large number of
questions still remain to be ans"ered. *evenston 199 concluded his discussion of some
problems in vocabulary research "ith a list of questions and suggestions for further
"or. 3ll these questions are "orth pondering, but they might usefully be
supplemented by some additional questions "hich have a slightly different emphasis.
-a are there any systematic differences bet"een "ell6no"n and recently acquired
"ords in a second languageJ -b do ne"ly acquired "ords in a second language pass
through any identifiable stages of acquisitionJ -c is it the case that *+ "ords everproduce behaviour that is indistinguishable from "hat "ould be e!pected "ith *1
"ordsJ -d are there any clear thresholds "hich it is necessary for an *+ "ord to cross
before it can be considered to be properly acquiredJ #f so, "hat types of activity lead to
these thresholds being crossedJ -e ho" is it that *+ "ords "hich are often learned as
paired associates of their *1 translations eventually come to operate in a "ay that is
relatively independent of their translationJ -f is the acquisition of ne" "ords affected
by such considerations as the morphological structure of *+ "ords, or their phonetic
structureJ -g are the le!ical errors of learners -e.g. malapropisms systematically
different from those of native speaersJ
7ur current understanding of vocabulary acquisition has almost nothing to say on any
of these points, and there is no doubt that "or along the lines suggested here could be
the beginnings of a very useful research programme.
