In Experiment 1 the concern with the appearance of bias is measured as a chronic state using the external motivation to respond without prejudice scale (Plant & Devine, 1998). In Experiment 2 it is manipulated by varying the race of the experimenter (black versus white). Time perception is assessed via a temporal discrimination task commonly used in the literature. Models of time perception identify arousal as a factor that causes perceived time to slow, and we speculate that arousal arising in intergroup interactions can alter time perception.e0182241-e0182241enCC BYhttp://creativecommons.org/licenses/by/4.0/AdolescentAfrican AmericansAnalysis of VarianceDiscrimination, PsychologicalEuropean Continental Ancestry GroupFacial RecognitionFemaleGoalsHumansMaleMotivationPsychological TestsRacismRegression AnalysisSocial BehaviorTime PerceptionYoung AdultArticle2021-01-28
