Abstract

The Purpose of the present study was to investigate experimentally the effects of the social categorization and outcome information on reducing intergroup bias in the cooperative task performance. In the first phase of the present study, members of the two groups either wore similar uniforms or different uniforms to distinguish the groups. In the second phase of the study, the two groups were combined and worked cooperatively on the tasks. And the outcome of the cooperative endeavor was manipulated so half the groups succeed and half failed. The main findings were as follows: (1) The one-group members (superordinate group) showed lower intergroup bias than the separate-two group members (subordinate group). (2) Success at the task increased the elimination of former group identies during intergroup cooperation. (3) The one-groups in the success feedback condition have lower degrees of bias than the separate-two groups in the failure feedback condition.
