Two studies examined relations between groups (humanities and math-science students) that implicitly or explicitly share a common superordinate category (university student). In Experiment 1, 178 participants performed a noninteractive decision-making task during which category salience was manipulated in a 2 (superordinate category salience)×2 (subordinate category salience) between-groups design. Consistent with the mutual intergroup differentiation model, participants for whom both…

Intergroup Similarity and Subgroup Relations: Some Implications for Assimilation

Two studies examined the effects of perceptions of similarity on relations between subgroups (humanities and math-science students) that share an active superordinate category (University of

The Other Side of We: When Outgroup Members Express Common Identity

Across both studies, high school students who learned that other ingroup members categorized students at both schools within the common identity of “students” showed less intergroup bias in evaluations and greater willingness for contact.

Superordinate and Subgroup Identification as Predictors of Intergroup Evaluation in Common Ingroup Contexts

We examined the combined effects of subgroup and superordinate group identification on intergroup evaluations within common ingroup identity contexts. In Studies 1 and 2 we observed a positive

Merging on mayday: subgroup and superordinate identification as joint moderators of threat effects in the context of European Union's expansion

Threat has been proposed as an important cause of prejudice with social identification moderating its effects. In the context of the expansion of the European Union, two studies (N = 216 students and

Subgroup identities as a key to cooperation within large social groups.

It is suggested that subordinate identities sometimes provide a more meaningful basis for self-definition and, when this is the case, activating subordinate level of identity might lay the foundation for enhanced cooperation within higher-order identities.

Superordinate identities and intergroup conflict: The ingroup projection model

This chapter summarises results from a research programme on the psychological basis of tolerance and discrimination in intergroup relations, with particular consideration of the role of

Assimilation and Diversity: An Integrative Model of Subgroup Relations

A model of sociostructural relations among subgroups within a superordinate category is presented. Contextualized by discussion of political and social psychological models of intergroup contact, we

Mutual Acculturation and Social Categorization: A Comparison of Two Perspectives on Intergroup Bias

Using Berry, Trimble, and Olmedo's (1986) theorizing as a foundation, the present article applies acculturation constructs to the domain of intergroup bias and compares them to social categorization

Battling ingroup bias with effective intergroup leadership

The results of two studies supported the hypothesis and intergroup leadership theory, demonstrating an intergroup relational identity is an effective strategy for improving intergroup relations.

When “They” becomes “We”: Multiple contrasting identities in mixed status groups

The present research investigated the development of multiple in-group identities among minority group members within a higher status majority. Explicit and implicit identification with the in-group



Superordinate goals and intergroup conflict

We have examined the effects of different types of superordinate goals on intergroup differentiation and attraction. On the basis of Social Identity Theory it was hypothesized that a reduction in

Subgroup differentiation as a response to an overly‐inclusive group: a test of optimal distinctiveness theory

Optimal distinctiveness theory (ODT; Brewer, 1991, 1993a,b) argues that people can respond to membership of an over ly inclusive group by engaging in a drive for subgroup distinctiveness. To test

Intergroup bias: status, differentiation, and a common in-group identity.

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 task, were informed prior to

Superordinate goals and intergroup behaviour: The effect of role ambiguity and status on intergroup attitudes and task performance

An experiment examined the effects of role ambiguity and relative group status in an intergroup situation where a superordinate goal was salient. One-hundred-and-fifty-six subjects in groups of three

The social dimension: Intergroup differences in group perceptions

The purpose of this chapter is to discuss the phenomenon of intergroup differences in group perceptions. My prime concern is with how and why groups differ in their perceptions of their own and other

The Criss‐cross Categorization Effect in intergroup discrimination

The effect of criss-crossing two dichotomous social categorizations on intergroup discrimination is studied. One hundred and thirty-nine 12–13 year old schoolchildren were randomly assigned to five

Previous research has shown that independent cross-cutting social categories reduce discrimination between groups. How-ever, the effect of correlated cross-cutting categories on intergroup relations

Generalized Intergroup Contact Effects on Prejudice

The intergroup contact hypothesis is tested with self-reports of 3,806 survey respondents in seven 1988 national probability samples of France, Great Britain, the Netherlands, and West Germany. With

Social categorization and behavioral episodes: A cognitive analysis of the effects of intergroup contact.

The effects of intergroup contact on stereotypic beliefs, it is argued, depend upon (1) the potential susceptibility of those beliefs to disconfirming information and the degree to which the contact
