Motivational biases in causal attributions of arousal.

Two studies hypothesized that the desire to seek ambiguity as to the cause of a particular state of arousal will increase if either that arousal state or its source is potentially threatening to self-esteem. In Exp I, 22 high- and 21 low-sex-guilt male undergraduates (as determined by the Mosher Forced Choice Sex Guilt Inventory) were shown either an arousing erotic movie or a nonarousing movie; in Exp II, 28 high- and 28 low-guilt females were led to believe that they were very aroused by pictures of nude men. Ambiguity was introduced into both situations by means of a bogus, nonthreatening, alternative arousal source (a placebo). Results indicate that high-guilt Ss were actively involved in the process of determining which source was arousing them. More importantly, this involvement appeared to be motivated by ego-defensiveness. In both experiments, when high-guilt Ss were confronted by an erotic stimulus, they chose to attribute arousal to the bogus source—and thus create ambiguity as to the actual cause and nature of their arousal—more than did low-guilt Ss.
