Memory processes of alcoholic and matched nonalcoholic volunteers were studied under sober, and two alcohol conditions. Alcohol administration significantly impaired registration, recall, and organization in both groups. These processes were differentially susceptible to alcohol's acute effects.

There were no significant differences between groups in the amount of information registered or recalled. However, alcoholics displayed significantly poorer organization under sober and intoxicated conditions, suggesting chronic impairment of abstracting ability due to alcohol.
