| Abstract: | During successive daily sessions, each of 8 29–44 yr old chronic male alcoholics received, in counterbalanced order, doses of beverage alcohol (.08, .4, .8, and 1.2 g/kg) prior to viewing nonerotic and erotic films. Measures of penile tumescence obtained by means of a penile plethysmograph showed a significant negative linear effect of increasing alcohol doses during the heterosexual and homosexual films. Ss' expectations about the effect of alcohol on sexual arousal and behavior were discrepant with these physiological findings. Consistently, Ss reported that alcohol would have no effect on their sexual arousal or would increase it. Results are discussed with reference to other studies, and it is concluded that penile tumescence is a convenient, reliable, and discriminating measure of male sexual arousal.
