The present study was conducted to investigate the effects of sociometric status, self-other relationship, and other person's evaluation of the subject's performance upon feelings toward that other person who had evaluated it (S→O) and upon the evaluation of his own and that other person's performance. Seventy-four female undergraduates served as subjects in this experiment. The results were as follows: In the low sociometric status group, whether they chose each other or not in a sociometric test, it was found that when other person's evaluation of subject's performance was positive, he enhanced S→O and the evaluation of his own and other's performance, but when it was negative, he lowered them. While in the high sociometric status group the above tendency in S→O and his evaluation of other's performance was found only when they did not choose each other. The influence of other's evaluation on the evaluation of his own performance was not verified.
