National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Effects of Realistic Stress and Procedural Interference in Experimental Lie Detection.

AD643707

Publication Date	1965
Personal Author	Kugelmass, S.; Lieblich, I.
Page Count	8
Abstract	Two different samples of police trainees were used to investigate: (a) the effect of realistic stress in experimental lie detection, (b) the possible interference with the GSR channel resulting from the simultaneous recording of blood pressure. It was found that: (a) GSR detection results under stress were essentially similar to those obtained in mild experimental situations, and far superior in detection efficiency to analysis of heart rate changes. (b) The introduction of a blood-pressure cuff inflated to 80 mm. Hg for the 90 sec. of interrogation (similar to actual field measurement conditions) reduced the efficiency of detection of the GSR channel. (c) There is some suggestion that GSR reactivity may be related to ethnic origin. (Author)
