The present study investigated the conditions that determine when intergroup cooperation will result in increased intergroup attraction. In the first phase of the study groups were led to believe that they were either competing, cooperating, or having no interaction with a second group. The results indicated that competition led to the least…

The effects on the development of interpersonal attraction of group outcome, race, and helping a less competent member of a cooperating interracial group were investigated in a 3 × 3 × 2 factorially designed experiment. The level of competence of group members was also varied. The Ss, who were White military servicemen from small towns and…

On a dot estimating task, the social categorization Protestant/Catholic was crossed with an experimentally manipulated categorization of over/underestimators. It was hypothesized that compared with single religion groups, discrimination against the outgroup and favoritism to the in-group would be significantly reduced in the mixed religion…

Tested the hypothesis that positively evaluated words, when paired with emotionally ambiguous slide photographs of Japanese and East Indian Canadians, would bring about a positive change in attitudes toward these 2 groups. Lower mainland (British Columbia) attitudes toward Japanese Canadians are positive and attitudes toward East Indian…

Several studies have found that the mere categorization of persons into groups is sufficient to promote intergroup discrimination. Out-group members may be convenient targets of bias because they are more deindividuated than in-group members. If so, then intergroup discrimination may be lessened through individuation of the out-group. In the…

It was hypothesized that intergroup cooperation would increase intergroup attraction to the extent that previous group identities were erased. In the first phase of the present study, two groups of subjects either competed or acted interdependently. Members of the two groups either wore similar uniforms or different uniforms to distinguish the…

Subjects were 153 children between the ages of five and nine, randomly assigned to one of three groups: Group 1 (Control), Group 2 (subjects viewed one film) or Group 3 (subjects viewed two…

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 categorization conditions: one simple, division into one ingroup and outgroup; and four crossed, half the ingroup members by one division are…

In the absence of information to the contrary, an individual tends to assume that members of an out group have values which differ from his own. The effect is even more marked for highly prejudiced persons. In the present paper two experiments are reported which extend the belief similarity hypothesis.

Predicted that intergroup attraction would most likely increase when Ss felt the environmental conditions interfered with successful cooperation as opposed to fostering a successful effort. Two groups of Ss (256 undergraduates) competed for extra credit and then cooperated to achieve a pre-determined performance level. In…
