Acute alcohol intoxication, negative affect, and autonomic arousal in women and men.
The present study tested the hypothesis that acute moderate alcohol intoxication is associated with reductions in experimentally-induced negative affect among 64 moderately drinking adult women and men. The effort incorporated a balanced placebo design, multiple measures of affective responses including cardiovascular and electrodermal activity, and control for phase of the sexual cycle among nonoral contraceptive women. Negative effect and psychophysiological responses to intoxication following stress manipulation were a complex function of beverage, expectancy, and gender. Expectation of a moderate alcohol dose among women at the premenstruum was associated with higher levels of self-reported anxiety, whereas alcohol consumption guised as tonic seemed to be related to tension reduction. Alcohol tended to increase autonomic arousal among men, but there were no significant changes in negative affect. Moderate intoxication was associated with increased heart rate regardless of gender, and alcohol expectancy increased levels of skin conductance for men and women.
