Style of Group Interaction, Anonymity, and Group Performance as Determinants of Egocentric Perceptions.

Members of cooperative groups usually claim greater personal responsibility for their groups performance after a group success than after a group failure, an attributional bias termed egocentrism. The present study attempted to replicate this basic effect and also to test the following hypotheses a egocentrism would be greater when subjects privately record their perceptions than when they expect to share those perceptions with other group memebers, and b face-to-face interaction among group members during the problemsolving phase of the groups activities would increase group identification and decrease egocentrism as compared to non-face-to-face interaction.
