The effects of group expectations and self-esteem upon self-evaluation.

This study explores the effect of a specific level of achievement upon an individual's evaluations of his performance when the achievement is relative to an aspiration level set by a group and to the member's stabilized expectations about himself as represented by his self-esteem. Ss were assigned to one of 4 conditions, composed of the combinations of high and low group expectations and relevance and non-relevance of task to the purposes of the group. Half of the Ss within each experimental condition were allowed to succeed and the other half made to fail. Several specific hypotheses within this framework were tested. "The group's expectations appear to have been more potent as a scale of reference than the individual's self-esteem in determining his evaluation of his performance. When the influence of the group was weakest (task was non-relevant) persons high in self-esteem… differed in the way they evaluated their performance. When the influence of the group was strongest (task was relevant) there was no difference in the way that persons high or low in self-esteem rated their achievement."
