The present research investigated a new method for discriminating non-guilty persons from guilty ones in polygraph test based on the autonomic response pattern. Electrodermal activity, respiration movement, and plethysmogram have been used as indices in polygraph test. However, electrodermal activity tends to be habituated and plethysmogram can not indicate the activity level of sympathetic nervous system precisely. We introduced normalized pulse volume (NPV) into polygraph test as a new autonomic index. NPV showed significant decrement in the critical than in the non-critical questions. The results confirmed that NPV was a sensitive index of the peripheral vascular tone. NPV was used as a reliable and valid autonomic index in later studies. For investigating correlation patterns of autonomic responses, we conducted factor analysis on responses induced by emotion-evoking stimuli. Three factors were extracted ; a factor of blood pressure and peripheral vessel, a factor of respiration am … More plitude and inter heartbeat interval, and a factor of electrodermal indices. This analysis showed that autonomic responses were patterned by physiological systems. We also found characteristic response changes in the critical question. We named these physiological changes "the critical-question pattern". The responses during the critical question of guilty subjects corresponded to the pattern, while the responses of non-guilty subjects did not. The results indicated that three information were useful to discriminate non-guilty subjects from guilty ones ; the number of significant differences, the percentage of the differences corresponded to the critical-question pattern, and the percentage of responses related to peripheral vascular resistance corresponded to the critical- question pattern. We examined the availability of latent class discrimination method for polygraph test. This new multivariate method conducted guilty/non-guilty discrimination based on how a given response follows the critical-question pattern in each physiological system. The performance of this method was better than other conventional multivariate analyses. Less

本研究探讨了一种基于自主反应模式的测谎仪测试中区分无罪者和有罪者的新方法。皮肤电活动、呼吸运动和体积描记图已被用作测谎的指标。然而，皮肤电活动具有习惯性，体积描记图不能准确反映交感神经系统的活动水平。我们将标准化脉搏容积（NPV）作为一个新的自主神经指标引入到多导生理测试中。NPV在关键问题上比在非关键问题上显著降低。结果证实，NPV是反映外周血管张力的敏感指标。NPV在后来的研究中被用作可靠和有效的自主神经指标。为了探讨自主神经反应的相关模式，我们对情绪诱发刺激引起的反应进行了因子分析。提取了三个因子，即血压和外周血管因子、呼吸和心率因子， ...更多信息 频率和心跳间期，以及皮肤电指标的一个因素。这一分析表明，自主反应是由生理系统模式。我们还发现了关键问题的特征反应变化。我们将这些生理变化命名为“关键问题模式”。有罪被试在批判性提问时的反应符合这一模式，而无罪被试在批判性提问时的反应不符合这一模式。结果表明，三个信息是有用的区分无罪的人有罪的，显着差异的数量，差异的百分比对应于关键问题模式，和周围血管阻力相关的反应的百分比对应于关键问题模式。我们研究了潜在类别区分方法在测谎中的有效性。这种新的多变量方法进行有罪/无罪的歧视的基础上，一个给定的响应如何遵循每个生理系统中的关键问题模式。这种方法的性能优于其他传统的多变量分析。少
