警告对共同目击者讨论后产生的错误记忆的影响

The Effects of warning on false memory resulting from co-witnesses discussion

采用误导信息干扰范式,研究了事件后正确诱导与事件后误导对共同目击者的记忆准确性的影响。实验1,要求被试接受事件后诱导信息后进行线索化自由回忆,结果发现,目击者对事件后正确诱导信息项目的记忆准确性显著提高;对事件后误导信息项目的记忆准确性显著下降,产生了共同目击者误导信息效应。实验2,研究了警告对目击者记忆准确性的影响。在回忆前警告被试共同目击者提供的事件后信息不完全正确,请按照自己的记忆来完成线索化自由回忆,讨论无警告组与讨论警告组比较发现,警告并没有改变事件后误导信息效应,也没有改变目击者对正确诱导项目的记忆准确性,说明共同目击者讨论所产生的诱导效应很强烈,并且不容易改变。

Using misleading information paradigm, we explored the differential effects that the true and the false of oost-event iniormatlon on recalling Ior co-witness event, we analyzeu memory accuracy. In Study 1, participants received post-event, and then completed 20-item cued-recall questionnaire, the result was that, participants who received the true post-event information were more accuracy than no discussion; participants who received the false post-event.information were less accuracy than no discussion. In study 2, participants were warned that they have received the post-event information meight be wrong, so, they recalled the event based on themselves＇ memory. The result was that, warning didn＇t change the accuracy. The findings reported in the current experiment suggest that memory conformation may result from memory change and be not easily changed.
