Abstract
The effects of both heavy social drinking and high familial alcoholism risk status on the cognitive performance of college men were examined in this study. A two by three factorial design was employed represented by two social drinking (heavy/nonheavy) and three familial risk groups (high, middle, and low). The cognitive performance tasks employed-group embedded figures, revised Beta mazes, mirror tracing, and symbol-digit paired associate learning-had all been previously shown to present difficulties to male acoholics. No evidence was obtained of a relationship between heavy drinking or familial risk and cognitive functioning, nor a meaningful interaction of these two independent variables. Little evidence was revealed for the "hangover hypothesis" as evidenced by a relationship between drinking behavior within the past week and cognitive performance. The findings are discussed in the context of previous findings in these areas and the general difficulties of interpretation posed in nonexperimental research based on subject variables.
