ABSTRACT: Using the Implicit Association Test (IAT), recent experiments have demonstrated a strong and automatic positive evaluation of White Americans and a relatively negative evaluation of African Americans. Interpretations of this finding as revealing pro-White attitudes rest critically on tests of alternative interpretations, the most obvious one being perceivers, greater familiarity with stimuli representing White Americans. The reported experiment demonstrated that positive attributes were more strongly associated with White than Black Americans even when (a) pictures of equally unfamiliar Black and White individuals were used as stimuli and (b) differences in stimulus familiarity were statistically controlled. 75 students at the University of Washington participated in the study. This experiment indicates that automatic race associations captured by the IAT are not compromised by stimulus familiarity, which in turn strengthens the conclusion that the IAT measures automatic evaluative associations.
