Abstract

Information given to witnesses after an identification decision greatly alters their impressions of the original event and importantly, their identification confidence. Two experiments investigated the possibility that the effect of feedback on confidence may be altered according to the strength of the witness's cues to accuracy. Experiment 1 used a manipulation of exposure duration to alter recognition accuracy prior to the delivery of confirming, disconfirming or no feedback. While the feedback effect was not different across exposure duration conditions, decisions that were made more quickly were less likely to show large changes in confidence due to feedback. Experiment 2 manipulated the distinctiveness of faces and showed that the effects of feedback on confidence, and on the resolution of the confidence judgement, were more pronounced when disconfirming feedback was given for distinctive faces and when confirming feedback was given for typical faces. These studies showed that the impressions that participants formed of their likely accuracy might moderate the effects of feedback on decision confidence. Copyright © 2006 John Wiley & Sons, Ltd.
