The Effects of Incentives on the Detection of Deception.

Abstract

A mock crime experiment was conducted to explore the effects of manipulating motivation to deceive on the physiological detection of deception using the control question test. Sixty subjects were assigned to one of four conditions in a 2 X 2 factorial design (two motivational states crossed with innocence or guilt). The motivation manipulation failed to produce any significant effects. The control question test performed reasonably well. The original examiners' outcomes with guilty subjects were 80% correct, 7% incorrect and 13% were inconclusive. With the innocent subjects the original examiners' outcomes were so correct, 17% incorrect and 33% were inconclusive. Electrodermal measures provided the greatest discriminability between innocent and guilty subjects followed by respiratory and cardiovascular measures. The results add to the already complex set of motivation results in the literature, and they were discussed within the context of Steller's systems theory, previous research, and research needed in the future.
