Stopping crime? The effect of crime re-enactments on eyewitness memory.

Crime re-enactments broadcast on television encourage witnesses to provide information regarding unsolved crimes. However, given that eyewitness memory can be altered through exposure to post-event information, it is possible that crime re-enactments may influence the memory of eyewitnesses. The current studies examined the effects of crime re-enactments on eyewitness memory. In two experiments (Experiment 1 with a distractor task, Experiment 2 without a distractor task), participants were shown one of three versions of a crime video that differed in their ambiguity. One week later half of the participants viewed a crime re-enactment. All participants then completed a guided free- and cued-recall task regarding the original event. Across both studies, exposure to the re-enactment did not improve eyewitness memory; instead, participants who viewed the re-enactment were more likely to accept the misinformation in the re-enactment. The findings shed light on potential issues with using crime re-enactments to elicit eyewitness accounts.
