The Effect of Alcohol on Emotional Response to a Social Stressor:
Michael A. Sayette, Daniel W. Smith, Mary Jo Breiner, G. Terence Wilson
Social drinkers were administered either an alcoholic, placebo or no-alcohol control beverage. Subjects were next informed that they were to give a self-disclosing speech about their body and physical appearance. Subjects' heart rate and videotapes of their facial expression were recorded during this instruction. Facial reactions to the Stressor were analyzed using a system based on the Maximally Discriminative Facial Coding System (Izard, 1979). Subjects who were intoxicated showed significantly less negative emotion, as measured by the facial expression analysis, than those subjects consuming either the control or placebo beverage. We attribute this effect of alcohol to its actions on subjects' appraisal of anxiety-inducing information. (J. Stud. Alcohol 53: 541-545, 1992)
