Abstract: | Subjects were led to perceive a trainee as either similar or dissimilar to themselves. During subsequent influence trials, subjects attempted to assess the causes of the trainee's performance and to employ rewards, punishments, or manipulations of the trainee's environment to optimize her performance. It was predicted that subjects would perceive the performance of dissimilar trainees as caused more by the dispositional factor of motivation than the performance of similar trainees, and that dissimilar trainees would thus be rewarded more upon success as well as punished more upon failure. The hypotheses were supported, and a model of reward-punishment behavior and attribution is discussed. |
