Don't ignore the other half: the impact of ingroup identification on implicit measures of prejudice

Recently several implicit measures of prejudice have been developed. Prejudice indices based on these measures are computed from response differences to positive and negative targets resulting from outgroup compared to ingroup stimuli. Up to now the focus of research involving these measures has mainly been on attitudes and relations to outgroups (i.e. negative attitudes towards the outgroup). It is suggested here that implicit measures of prejudice are also influenced by one's relation towards the ingroup (i.e. ingroup identification), because they involve ingroup as well as outgroup stimuli. A correlational study and an experiment were conducted that supported this prediction. Implications for the application of implicit measures are discussed. Copyright © 2005 John Wiley & Sons, Ltd.
