THE INFLUENCE OF ASSESSEE PERFORMANCE VARIATION ON ASSESSORS’JUDGMENTS
通过模拟评估中心实验，发现被评估者绩效变化（内部或之间）会导致对比效应，影响评分准确性，但某些情况下对比效应反而提高评分准确性。
Assessors evaluated assessees’performances in one of three performance conditions in an assessment center simulation: a consistent performance condition, a within‐assessee performance variation condition, or a between‐assessee performance variation condition. Contrast effects influenced ratings of assessees when there was variation in performance within assessees. For each assessee, the low target performance was rated lower when the assessee's prior performance had been dissimilar (high) than when the assessee's prior performance had been similar (low). Contrast effects also infiuenced assessors’ratings of the target assessee when there was variation in performance among assessees. The low performing target assessee was rated significantly lower when he was evaluated with two high performers than when he was evaluated with two low performers. In addition, ratings obtained when there was performance variation among assessees were more accurate than those obtained when there was no performance variation, suggesting that under some circumstances contrast effects may not lead to inferior judgments.
