Three studies were conducted to investigate the relation between perceptions of group entitativity and group similarity. The first two studies tested whether entitativity and similarity would be perceived differently in participants' ingroups and outgroups. Across several different group types, we found that, in comparison to outgroups, ingroups were perceived to be relatively more entitative than outgroups, whereas outgroup members were perceived to be highly similar in comparison to ingroup members. The results of Study 3 showed that manipulation of group entitativity influenced perceptions of group entitativity but not of group similarity, whereas manipulation of similarity influenced perceptions of group similarity but not of group entitativity. The results of these studies provide support for the contention that entitativity and similarity are distinct (though related) concepts that function differently in group perception.

Two experiments show that repeated exposure to information about a target person reduces individuation and thereby increases stereotyping of the target person based on social group memberships. The eVect is not due to familiarity-induced liking (the mere exposure eVect), nor is it mediated by increased accessibility of the target's social category, nor by increases in perceived social judgeability. The results are most consistent with the use of feelings of familiarity as a regulator of processing mode, such that familiar objects receive less systematic or analytic processing. In everyday life, frequent exposure to another person ordinarily produces not only familiarity but also liking, individuated knowledge, and friendship, factors that may eVectively limit stereotyping. But when previous exposure is unconfounded from these other factors, its eVect can be to increase stereotyping.
