The present study was designed to investigate the effect of negative evaluation to group performance upon members' interpersonal relation and group performance itself. It was hypothesized that members in incompatible groups would be more affected by negative evaluation than members in compatible groups. The difference would be reflected in interpersonal relation and group performance. 80 4th-grade boys and girls were assigned to four dyadic exprimental and control groups. Four groups were compatible-negative evaluation (P-F), incompatible-negative evaluation (N-F), compatible-non negative evaluation (P-C) and incompatible-non negative evaluation (N-C). Compatible and incompatible groups were constructed by the result of a sociometric test. The task was to trace S-figure in co-operation with partner as fast as possible. Performance was judged on two dimensions, speed and errors. The change in interpersonal relations was measured by 6 questionnaire items. Results were summarized as follows: 1. In interpersonal relations, the effect of negative evaluation was the greatest in N-F groups. 2. The change in interpersonal relation was not reflected in group performance. 3. Errors were decreased by negative evaluation. 4. When negative evaluation was given, boys tended to lower their self-evaluation, while girls tended to heighten their self-evaluation.
