| Abstract: | Investigated the effects of a short training session designed to reduce halo error in performance ratings. 90 low and middle managers rated 1 of 6 hypothetical first-line supervisors on 6 performance dimensions according to behavior displayed in a prepared vignette. Ratings were taken prior to and following the 5-min training session, with rater-ratee combinations counterbalanced. The vignettes were developed to contain previously scaled behavior examples, thus enabling the calculation of "true" criterion scores for each dimension. Comparisons between these "true" criterion and the performance ratings revealed that the training session significantly reduced halo, while leaving validity of the ratings generally unaffected. Performance ratings completed after training possessed lower reliability, although raters provided somewhat more accurate performance profiles.
