The Effects of Rater Stress on Performance Rating Accuracy
This study examined the effects of rater stress on halo error, severity error and rating accuracy in performance appraisal. Eight-four participants completed either a stressful or nonstressful in-basket exercise, either before or after observing the videotaped performance of a manager. They then rated the manager on several performance dimensions. Ratings provided by participants completing the stressful in-basket were less accurate than those provided by participants completing the nonstressful in-basket. However, ratings provided by these two groups showed no differences in halo or severity error. In addition, raters who completed the in-basket after seeing the target performance but before rating that performance provided less accurate ratings than those completing the in-basket before observing and rating the performance. These result indicate that rater stress may lead to greater appraisal inaccuracy, and that this inaccuracy is largely a function of faulty information retrieval.
