Sexual Attitudes Moderate the Effects of Alcohol Intoxication on Women's Risk Judgments

This study evaluated the effects of alcohol intoxication, sexual attitudes, and sexual victimization history on the cognitive processes underlying undergraduate women's risk judgments. Participants were 116 unmarried, undergraduate women between the ages of 21 and 29. The sample was diverse ethnically and composed primarily of heterosexual women. Stimuli were written vignettes describing social situations that varied on dimensions of sexual victimization risk and potential impact on women's popularity. Participants were assigned randomly to an alcohol or a no-alcohol condition, and completed an explicit classification task in which they rated how risky each situation was in terms of their having an unwanted sexual experience. They then completed the Sexual Experiences Survey (SES) and the Sociosexuality Scale (SS); SES responses were used to quantify the severity of victimization experiences, and SS responses were used to measure endorsement of positive attitudes toward casual, impersonal sex. Although there was no main effect for condition, higher sociosexuality predicted use of higher thresholds for judging situations as risky. Importantly, sociosexuality interacted with condition such that higher sociosexuality predicted lower sensitivity to risk information in the alcohol condition but not in the no-alcohol condition. More severe victimization history predicted increased use of popularity impactwhen judging risk. This study emphasizes the importance of identifying specific cognitive processes affected by alcohol that may explain why women have difficulty processing contextual cues signaling risk in social situations. It demonstrates also the relevance of examining individual difference factors that may exacerbate the relationship between intoxication and cognitive processing of risk-relevant information.
