Book excerpt: Lie detection, as currently practiced, relies heavily on the use of measures of autonomic activity. It is presumed that lying is emotionally more arousing than truth telling that the increase in affective arousal is mirrored in the measures used in the conventional polygraph. We do not dispute the possibility that telling an untruth may be emotionally arousing. But this is not the entire picture. Zuckerman and Driver (1985) presented a four factor mode) of behavioral cues to deception, which, in addition to factors such as: attempted control, arousal, and affect, also includes cognitive factors, the category into which the present work falls.
