The effect of post-identification feedback on the recall of crime and perpetrator details

The present study examines the effect of identification feedback on the quantity and accuracy of crime event details recalled, willingness to attempt misleading questions and confidence in the accuracy of these details. All participants (N = 60) viewed a short video clip of a staged building society robbery and then made a false identification of the robber from a target-absent photospread. Eyewitnesses were next given confirming feedback (i.e. told that they had identified the suspect), disconfirming feedback (i.e. told that they had failed to identify the suspect) or no feedback. All eyewitnesses then attempted a series of short-answer questions relating to details about the robber, accomplice, victim, building society, theft and getaway. Disconfirming feedback significantly reduced eyewitness confidence in recall accuracy but there was no significant effect of feedback on the overall quantity and accuracy of details recalled or willingness to attempt misleading questions. The theoretical implications of these results are discussed.
