基于事件相关电位的测谎技术研究进展

事件相关电位测谎技术通过比较靶与非靶刺激引出的P300差异，来推测被试者对靶刺激内容是否知情，众多的国内外实验研究已证明了此种测试方式的可行性，但却在研究中存在诸多问题，因此文章针对已有研究中存在的问题提出应该以真实的案件情境为测试背景，选择被试者经历过的环境或用过物品为靶刺激，同时通过测前谈话等方式来消除非认知因素的影响。

The progress of event-related potential as an indicator of detecting information in field of polygraph examinations

Event-Related Potential Detection Technique infers whether the man tested knows the content of target stimulus by way of comparing the differences of P300 that come from target and non-target, The possibility of this detection technique has been proved through a lot of domestic and foreign tests. In this article, author brings up that the true case situation should be the detection background, the situation or things that the man tested has experienced or used should be made as the target stimulus, and the effect of cognitive factors should be cleared up by the way of talk before test.
