An examination of deception as a conditioned stimulus. / J. James Tomash

Swansea University Author: J. James Tomash

Abstract

The polygraph, and other methods o f lie detection, measure the physiological arousal thought to accompany attempts to deceive. Traditional methods of lie detection, however, have failed to acquire the accuracy and consistency necessary to be relied upon in important applications. The reason for thi...
