Abstract

Recent research shows that post-identification feedback affects subsequent identification performance in single-suspect crimes: confirming feedback improves subsequent identification performance and disconfirming feedback impairs performance. The present research demonstrates similar effects in multiple-culprit crimes. Witnesses viewed a mock crime and attempted to identify two different culprits from separate lineups. Following the first lineup witnesses received disconfirming feedback or no feedback. Identification performance for the second lineup was measured via ROC curves and compound SDT estimates of discriminability. Disconfirming feedback (vs. no feedback) following an attempted identification of one culprit impaired the identification of a different culprit from a subsequent lineup.
