Abstract
Thepurposeofthisstudywastoexaminewhetheraculturally-undesirablebehavior
(playingwithapen)wouldbelesslikelytobemimickedbyparticipantsthananeutral
behavior(claspingoneshands).Sixtyparticipantstookpartintheexperiment,in
whichthetypeofbehavior(undesirablevs.neutral)wasawithin-participantfactor.
Duringtwoexperimentalsessions,eachparticipantinteractedwithaconfederatewho
engagedinoneofthetargetbehaviors.Theresultshowedthatnonconsciousmimicry
occurredonlywiththepen-playbehavior.Also,onlymalesshowedmimicryofthepenplaybehavior.Somepossiblereasonsfortheunexpectedresultsarediscussed.
Recently,socialpsychologistshavebeeninterestedinthesocialfunctionsofnonconscious
mimicry‐peoplesautomatictendencytoimitateotherspostures,mannerisms,facial

confederate'srubbingofhis/herface,shakingofhis/herfoot(Chartrand&Bargh,1999;
Cheng&Chartrand,2003;vanBaaren,Maddux,Chartrand,deBouter,&vanKnippenberg,
2003),andplayingwithapen(vanBaarenetal.,2003).Suchtendencytomimicothers'
mannerismsappearsmeaninglessatfirstglance.However,recentresearchhasshownthat
nonconsciousmimicryhasanimportantsocialfunction(Lakin,Jefferis,Cheng,&Chartrand,
2003).InChartrandandBargh's(1999)experiment(Experiment2),forexample,each

Participantswere60undergraduates(30malesand30females)atNaraUniversity,Japan.
Theywerepaid500yenfortheirparticipation.Thirtyparticipants(15malesand15females)
wereassignedtothepen-handconditionandtheremainingthirtyparticipants(15malesand
15females)wereassignedtothehand-pencondition.Therewasabetween-participant

Procedure
Uponarrival,eachparticipantwasaskedtostayinawaitingroom.Afterarrivalofthe

questionnairewasintroducedsothatapenwouldnecessarilybeplacedonthewritingarm.
Aftercompletionofthequestionnaire,theexperimenterexplainedthenatureofthe

Results
Thevideorecordingswerecodedbyfourindependentjudgeswhowereblindtothe
conditionsofparticipants.Eachvideorecordingwascodedbytwoofthejudges.Thejudges

Discussion
Theexperimentwasaimedattestingthehypothesisthatnonconsciousmimicrywould
bemorefrequentlyobservedforaculturally-neutralbehavior(i.e.,hand-claspingbehavior)
thanaculturally-undesirablebehavior(i.e.,pen-playbehavior).Thehand-claspingbehavior
wasmorefrequentlyengagedinthanthepen-playbehavior.Ofthe60participants,24
participantsclaspedtheirhandsatleastonceduringtheexperiment,whilellparticipants
playedwithapenatleastonceduringtheexperiment.Thispatternseemsconsistentwiththe
assumptionthatthepen-playbehaviorwaslessculturallydesirable.Thereisaquestionasto
whynonconsciousmimicrydidnotoccurwiththehand-claspingbehavior.Accordingtothe
confederates,thehand-claspingbehaviorwaslessnoticeablethanthepen-playbehavior.
Theybelievedthatamajorityoftheparticipantsweresoconcentratedonthetaskthatthey
didnotlookattheconfederateatall.Therefore,totestthehypothesis,morenoticeabletarget
behaviorsareneeded.
