Affective influences on stereotype judgements

What role does affect play in stereotype judgements? This experiment investigated mood effects on perceptions of Asian (heterosterotype) or Causcasian (autostereotype) characters who were part of a same-race or a mixed-race dyad. We expected that mood should (a) distort stereotype judgements in a mood-consistent direction, and (b) that mood biases should be stronger for mixed-race dyads that require more detailed and inferential processing. Happy, neutral or sad mood was induced in subjects (n=198) using an audio-visual mood induction procedure in an allegedly separate experiment. Subjects were then asked to form impressions of Asian or Caucasian targets associated with a same-race or an other-race partner. As predicted, we found consistent mood-congruent biases in such. However, both positive and negative mood effects were significantly greater when a target was part of a mixed-race dyad, a condition presumably requiring more detailed and substantive inferential processing. These findings are interpreted in terms of current affect-cognition theories, and the implications of the results for everyday affective influences on stereotype judgements are considered.
