Hypothesized that heightening ingroup cohesion would increase discrimination toward an
outgroup. This prediction was not supported. Instead, it was found that for the most part, only …

ingroup and outgroup members were either similar or dissimilar to themselves on attitudes …

to promote intergroup discrimination. Out-group members may be convenient targets of bias …

Four experiments addressed the different forms and functions of in-group bias in different
contexts. The authors proposed 2 functions: an identity-expressive function and an …

We examined the impact of intergroup similarity on two aspects of intergroup relations.
Drawing on social identity and belief congruence theory, we hypothesized that—at high …

The prediction from several theories of interpersonal relations that intergroup similarity
would lead to less differentiation and more attraction was contrasted to a hypothesis from …

The present research examined factors that moderate and mediate the reduction of
intergroup bias. Two 3-person laboratory groups, which had first worked separately on a …

Examined the effects of 5 levels of intergroup orientation on (a) member evaluations of both
ingroup and outgroup and (b) proxemic behavior both within and between groups. Ss were …

The concept of similarity occupies an important place in several theories of social relations.
An experiment was designed to examine the effects of both status and attitudinal similarity …
