The influence of discrepant perceptions of performance and amount of performance information on future performance judgments

The purpose of the present study was to investigate the effect of amount of performance information (API) and discrepant self-appraisal information on the modification of supervisor's original performance ratings. Confidence in original ratings was expected to mediate the relationship between API and modification of ratings after begin presented with discrepant self-appraisal information. The results indicated that AP! was not related to modification of original ratings. Moreover, API was unrelated to confidence in original ratings. However, as expected there was a negative relationship between confidence and modification of ratings, although the correlation was not significant. Additional analyses indicated that supervisors in the low API condition became more confident in their final performance ratings after viewing self-ratings than those in the high API condition. The implications of the findings of this study are discussed.
