Self-Expression While Drinking Alcohol: Alcohol Influences Personality Expression During First Impressions

Abstract

People are motivated to be perceived both positively and accurately and, therefore, approach social settings and adopt means that allow them to reach these goals. We investigated whether alcohol consumption helps or hinders the positivity and accuracy of social impressions using a thin-slicing paradigm to better understand the effects of alcohol in social settings and the influence of alcohol on self-expression. These possibilities were tested in a sample of 720 participants randomly assigned to consume an alcohol, placebo, or control beverage while engaged in conversation in three-person groups. We found support for the hypothesis that alcohol (compared with placebo or control) increased the positivity of observers’ personality expression, but did not find support for the hypothesis that alcohol increased the accuracy of personality expression. These findings contribute to our understanding of the social consequences of alcohol consumption, shedding new light on the interpersonal benefits that alcohol can foster.
