Abstract
Decisions to commit crimes are often made under the influence of visceral feelings such as anger or sexual arousal. Rational choice models of offender decision-making assume that individuals can anticipate, in an unaroused state, their responses to such visceral feelings. This assumption is tested in an experiment in which sexually aroused and nonaroused males predict their own behavior in a date rape scenario. Aroused and nonaroused participants were asked a battery of questions designed to measure their perceptions of the costs and benefits of acting in a sexually aggressive manner, their level of arousal, and a probabilistic prediction as to how aggressively they would act in the conditions described in the scenario. The authors find that sexual arousal does increase subjects' expectations of their own sexual aggressiveness and that this impact is not mediated by perceptions of the costs or benefits of such aggression.
