Social identity theory holds that social group memberships become part of the psychological self, affecting thoughts, feelings, and behavior. However, tests of this hypothesis have mainly involved judgmental dependent measures. A method is suggested that can provide more direct evidence. Discusses use of that method. (KW)

Considers two determinants--one cognitive and the other motivational--of perceptual fluctuations of in-group variation. Results indicate that when motivation to protect social or personal identity from threat is absent, priming the in-group social category promotes a homogeneous and cohesive view of the in-group.

Reviews the literature on unidimensional and multidimensional models of cohesion and describes cohesion as a multidimensional construct with primary and secondary dimensions. Found that primary dimensions described the cohesiveness of all or most types of groups, whereas secondary dimensions only described the cohesiveness of specific types of…

Examined whether group members differ in the number of in-group subtype distinctions that they draw. Drawing on results of two studies, found that members of groups whose primary function is intragroup interaction (fraternities, sororities, athletic teams) draw more subtype distinctions within their own group than within other groups.

Tested the hypothesis that training in statistical reasoning inhibits erroneous group stereotypes. In study one, 60 students were assigned to a control or one of two training conditions focused on training in the logic of analysis of covariance. Study two (N=82) replicated study one. Study three (N=44) tested an alternative explanation, providing…
