认知脑电位检测在目击证人心理面孔重建中的应用

检验目击证人对犯罪嫌疑人面孔记忆的正确性是一项困难的工作。在证人面孔记忆的语义提取过程中,严格遵守完形原则,尽量减少影响证人记忆和再认的因素,把握细节,可以提高目击证人心理面孔重建的质量。认知脑电位检测法可以通过对记忆反应的脑电图成分、潜伏期、波幅等指标的测量,有效判断证人对列队辨认中的面孔是否存有记忆。本文对脑电位检测在目击证人心理面孔重建中的研究和应用进行综述,希望能为相关研究和实践提供参考。

Progress on cognitive brain potentials detection in psychological face reconstruction of eyewitnesses

It is difficult to verify the correctness of the suspects＇ faces in the eyewitnesses＇ memory.Gestalt principle should be strictly adopted during the process of extracting semantic memory about the suspects＇ faces.Reconstruction can be improved through controlling the details and minimizing factors that could affect the memory and recognition of the witnesses.Cognitive brain potential detection can be used to determine whether a witness can effectively identify the faces from line ups by measuring EEG components of memory,latency and amplitude of EEG and other indices.This article gives an overview of the researches and applications on brain potential detection in eyewitnesses＇ psychological face reconstruction,so as to provide reference for related research and practice.
