The impact of positive mood and category importance on crossed categorization effects.
Four studies examined the effect of positive versus neutral affect on preference among potential discussion partners who were members of two in-groups, two out-groups, or both an in-group and an out-group (crossed targets). The importance of targets' category memberships was manipulated by idiographically based selection. Positive affect elevated evaluation of crossed targets with a dominant (differentially important) in-group (Study 1). When categories were made equally important, positive affect had no impact (Studies 2 and 3). Study 4 presented crossed targets with both equally and differentially important group memberships and showed that differential category importance (dominance) is necessary for positive affect to influence judgments about them. These results are explained by the broadened categorization induced by positive affect.
