Neuropsychologic decrements as a function of alcohol intake in male students

Drinking history and sober neuropsychologic performance were examined in 45 male university students between the ages of 21 and 30 yr. Sober performance on the Shipley-Hartford Institute of Living Scale was significantly and inversely related to the amount of alcohol consumed per drinking event. Neither frequency of drinking nor lifetime alcohol consumption were significantly related to cognitive performance in controlled multiple regression equations. These findings emphasize the need for more information about the effects of social drinking on health.
