Abstract
To explore the relationship between social drinking and nonintoxicated cognitive performance, 106 well educated male social drinkers were administered memory, visuoperceptive and concept-formation tests. Partial correlational analysis, with age and IQ estimates partialed out, was used to assess the relationship between patterns of alcohol consumption and performance on the neuropsychological tests. Current quantity of alcohol consumed per drinking occasion correlated significantly with some cognitive measures, and current frequency of alcohol use was also related to certain measures. When the total sample was divided into heavy and light-moderate social drinkers, significant correlations between drinking variables and cognitive performance continued to be evident, especially for the heavy social drinkers. There were no significant differences between the cognitive and light-moderate social drinkers. These results offer some support to previous investigations concerned with the detrimental effects of social drinking, but conceptual and methodological issues dictate caution in drawing definitive conclusions from present correlational data.
