Differential effects of intergroup contact for authoritarians and social dominators: a dual process model perspective

Intergroup contact is among the most effective ways to improve intergroup attitudes. Research examining whether the effects of contact are contingent on individual differences is limited, however. The authors test a dual process model perspective of individual differences in contact and prejudice. Their model predicts that intergroup contact should be particularly effective for people high in right-wing authoritarianism, but not those high in social dominance orientation, because these ideological attitudes are driven by different underlying motivational goals. The authors confirm these hypotheses in longitudinal (N = 805) and cross-sectional (N = 1,343) national probability samples. They also isolate perceived social threat, but not competitive threat, as a mediator for the interaction of right-wing authoritarianism and contact on prejudice. The authors elaborate on the individual difference mechanisms that facilitate and inhibit the effects of intergroup contact on prejudice and discuss how these relations may depend on contextual factors and the varying functions of prejudice.
