Unwillingness for contact with outgroup members is a form of prejudice. In two studies, we tested the proposition that perceived competence has an indirect effect on willingness for intergroup contact through its effect on realistic threat, and that perceived warmth moderates this relationship. In Study 1, Hong Kong students (N = 144) rated the perceived warmth and competence of an outgroup, Mainland Chinese students, as well as the extent to which they perceived the group as presenting a realistic threat, and willingness for contact with them. In Study 2 (N = 205), we attempted to manipulate the warmth (high vs. low) and competence (high vs. low) of an unfamiliar outgroup, and tested the effects on realistic threat and willingness for intergroup contact. In both studies, we found an interaction effect between warmth and competence in the prediction of realistic threat. When the outgroup was perceived as warm, competence was found to have a negative association with realistic threat (Study 1), whereas when the outgroup was perceived as lacking warmth, competence was found to have a positive association with realistic threat (Study 2). In both studies, perceived warmth moderated the indirect effect of perceived competence on willingness for intergroup contact. Implications for the role of warmth and competence stereotypes in threat perception and prejudice are discussed.
