撒谎是一件日常生活事件,历史上有很多种测谎方法。事件相关电位(ERP)测谎是根据案情设置不同内容的靶和非靶刺激,比较两者引出的P3波幅和波面积,判定受试者是否撒谎。本文介绍了ERP测谎技术的产生背景,ERP测谎的机制,国内ERP测谎的研究进展,ERP测谎的影响因素,并进行了总结和展望。
Lying is a daily life event, there are a variety of history polygraph method. Event-related potentials (ERP) polygraphs are target and non-target stimuli that are set according to different circumstances and compared with the amplitude and wave area of P3 derived from the two to determine whether the subject is lying or not. This article introduces the background of ERP polygraph technology, the mechanism of ERP polygraph, the research progress of domestic ERP polygraph and the influencing factors of ERP polygraph.
