Credibility assessment: Psychophysiology and policy in the detection of deception
Current and developing techniques for detecting deception are evaluated. Following a brief history of lie detection, the authors thoroughly examine traditional polygraphy. An exploration of the technical and methodological aspects of polygraphy then precedes a discussion of the use of the polygraph in screening, criminal investigations, sex offender monitoring, and in court cases. Problems and issues affecting polygraph outcomes, such as examiner bias, signal to noise ration, and various countermeasures are then explored. Finally, developing lie detection technologies, such as voice stress analysis, thermal imaging, pupillometry, brain wave assessment, and functional magnetic resonance imaging, are evaluated. The authors conclude that, despite recent advances in deception detection technology, continuing research is necessary to assess the accuracy of these instruments and the specific arenas in which each technique is most useful.
