Eyewitnesses to crimes are regularly under the influence of drugs, such as cannabis. Yet there is very little research on how the use of cannabis affects eyewitness memory. In the present study, we assessed the effects of cannabis on eyewitness recall and lineup identification performance in a field setting. One hundred twenty visitors of coffee shops in Amsterdam viewed a videotaped criminal event, were interviewed about the event, and viewed a target-present or target-absent lineup. Witnesses under the influence of cannabis remembered significantly fewer correct details about the witnessed event than did sober witnesses, with no difference in incorrect recall. Cannabis use was not significantly associated with lineup identification performance, but intoxicated witnesses were significantly better at judging whether their lineup identification was accurate. Theoretical and practical implications of the findings are discussed.
犯罪的目击者经常受到毒品的影响，比如大麻。然而，关于使用大麻如何影响目击者记忆的研究却非常少。在本研究中，我们在实地环境中评估了大麻对目击者回忆及列队辨认表现的影响。120名阿姆斯特丹咖啡店的顾客观看了一段犯罪事件的录像，接受了关于该事件的询问，并观看了一个有目标人物或无目标人物的列队。受大麻影响的目击者记住的关于所目睹事件的正确细节明显少于清醒的目击者，错误回忆方面则没有差异。大麻使用与列队辨认表现没有显著关联，但醉酒的目击者在判断自己的列队辨认是否准确方面明显更出色。我们讨论了这些发现的理论和实际意义。
