The Effects of Augmented Physiological Feedback on Detection of Deception

Abstract

The purpose of this study was to assess the effects of two types of augmented physiological feedback (APF) on the reliability and accuracy of probable-lie comparison question test (CQT). Two hundred and ten college students participated in the study half of whom were guilty of a mock crime and half innocent. During questioning, one group received skin conductance feedback, a second group received composite feedback (skin conductance, cardiograph, and respiration), and a third group received no feedback. The results indicated that APF did not increase detection rates above that of no-feedback group in this study. However, APF did decrease the rate of habituation during repetition of the question sequences thus allowing for greater discrimination between innocent and guilty participants as the CQT progressed.
