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.
电视上播放的犯罪重演节目鼓励目击者提供有关未解决犯罪的信息。然而，鉴于目击者的记忆可能会因接触事件后的信息而改变，犯罪重演有可能影响目击者的记忆。当前的研究考察了犯罪重演对目击者记忆的影响。在两项实验中（实验1有干扰任务，实验2无干扰任务），向参与者展示了三个版本的犯罪视频之一，这些视频在模糊程度上有所不同。一周后，一半的参与者观看了犯罪重演。然后，所有参与者都完成了一项关于原始事件的引导式自由回忆和线索回忆任务。在两项研究中，接触重演并没有改善目击者的记忆；相反，观看重演的参与者更有可能接受重演中的错误信息。这些发现揭示了使用犯罪重演来获取目击者陈述可能存在的潜在问题。
