Memory conformity may occur when a person's belief in another's memory report outweighs their belief in their own. Witnesses might be less likely to believe and therefore take on false information from intoxicated co-witnesses, due to the common belief that alcohol impairs memory performance. This paper presents an online study in which participants ( = 281) watched a video of a mock crime taking place outside a pub that included a witness either visibly consuming wine or a soft drink. Participants then read a statement from the witness that varied in the number of false details it contained before being asked to recall the crime. We found that the intoxicated witness was regarded as significantly less credible, but participants were not less likely to report misinformation from them. This suggests that intoxication status impacts one's perception of how credible a source is, but not one's ability to reject false suggestions from this source. Our findings reinforce the importance of minimizing co-witness discussion prior to interview, and not to assume that people automatically (correctly or not) discount information provided by intoxicated co-witnesses.
当一个人对他人记忆报告的信任超过对自己记忆的信任时，可能会出现记忆顺应。证人可能不太相信醉酒的共同证人，并因此接受错误信息，因为人们普遍认为酒精会损害记忆表现。本文介绍了一项在线研究，参与者（n = 281）观看了一段模拟犯罪的视频，犯罪发生在一家酒吧外，视频中有一名证人明显在喝葡萄酒或软饮料。参与者随后阅读了证人的一份陈述，陈述中包含的错误细节数量各不相同，然后被要求回忆犯罪情况。我们发现，醉酒的证人被认为可信度明显较低，但参与者报告来自他们的错误信息的可能性并没有降低。这表明醉酒状态会影响一个人对信息来源可信度的认知，但不会影响其拒绝该来源错误暗示的能力。我们的研究结果强化了在询问前尽量减少共同证人讨论的重要性，并且不要假定人们会自动（无论正确与否）忽略醉酒共同证人提供的信息。
