Abstract: Extracting the memory of witnesses for the faces of the suspects is a difficult task. Because the witnesses may confront a variety of factors in the process of memorizing faces, as well as the influences of extraction and recognition memory, it would lead to face psychological reconstruction of distortion. After all, from the view of cognitive and experimental psychology, analyzing the factors of affecting the psychological rehabilitation and extracting memory with the best means can enable face reconstruction reliability maximum. Cognitive which has potential in the field of memory test is getting more sophisticated, so the eyewitness recognition, whether is correct or not, has a reliable reference. From the ERP of the memory responses analysis, it can determine the witness whether remember the faces which appear on parade.

摘要： 提取目击证人对犯罪嫌疑人的面孔记忆是一项困难的工作，由于证人在识记面孔时有多种影响因素，在提取和再认记忆时又会有各种认知因素的影响，导致面孔心理重建的失真。因此，从认知心理学和实验心理学的角度入手，分析影响心理重建的因素，并用最佳的手段提取记忆，可以使面孔重建的可靠性最大化。认知相关电位在记忆检测领域的日臻完善，使目击证人的再认正确与否有了可靠的参照，从记忆反应的脑电图形分析，可以有效判断证人对列队辨认中的面孔是否存有记忆。
