事件相关电位在刑事测谎中的基本原理和方法

Basic Principle and Method of Event Related Electric Potential in Criminal Polygraph

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,即得到无法伪装和隐藏的脑电位的波幅、波的正负极性、潜伏期等参量变化为检测依据的新的心理测试技术。尽管事件相关电位测谎还存在着一定的局限性,但是该技术的诞生和应用将推动心理测试技术的科学化发展,成为刑事技术当中的锐利武器。

The event related electric potential polygraph is to the information processing cerebral activity electricity physiology demonstration foundation, through the direct read case related brain potential shift, namely obtains is unable to camouflage and hideaway brain electric potential parameter changes and so on wave amplitude, wave positive and negative polarity, incubation period for the examination basis new psychological test technology. Although the event related electric potential polygraph also has certain limitation, but this technology The birth and the application will impel the psychological test technology the scientific development, becomes in the middle of the criminal technology the sharp weapon.
