Alcohol-Influenced Nonverbal Behaviors During Discussions About a Relationship Problem

摘要

We examined the effect of alcohol intoxication on the display of nonverbal behaviors during discussions with dating partners about a relationship problem. Forty-four heterosexual dyads engaged in a 7-min conversation about a hypothetical infidelity. Males were randomly assigned to drinking condition (sober or .08 g/dl) and their behaviors were coded for behavioral expressivity, verbal expressivity, positive affect, and anxiety at 30 s and 3 min into the interaction. A series of 2 (drinking condition) × 2 (time) repeated measures analyses indicated that as time passed, drinkers nonverbally conveyed more agitation and less positivity, and consequently less pro-relational behavior. Further, drinkers showed more behavioral variability over time compared to their sober counterparts. The implications of these results for understanding alcohol-influenced communication in close relationships are discussed.
