事件相关电位测谎的心理测量学要素分析

Analyzing the Psychometric Factors of Event-related Potentials in Lie Detection

事件相关电位测谎是在对信息加工脑活动的电生理显示的基础上,通过直接读取案件相关的脑电位变化,来判别被测人是否与案件有关的心理测试方式。文章从心理测量学的角度分析此种测试方式的科学性、客观性并认为该测试方式的指标选择具有代表性,可测性和可接受的信度和效度。

In criminal lie detection, the examination of the changes in event-related potentials read from the electrophysiological display of information processing in the brain can determine whether the suspect under test is involved in the case or not. The article, therefore, focuses on the scientificity and objectivity of event-related potential in criminal lie detection from a psychometric view, and argues that the indicators selected by this kind of detection are indeed representative, measurable and with acceptable reliability and validity.
