The effect of alcohol intoxication on primary and secondary processes in male social drinkers

The acute effects of alcohol intoxication on cognitive style and on locus of control was investigated in an experimental setting. Sixty male subjects were randomly assigned to either an Alcohol, a Placebo, or a Control group. The alcohol dose was 1.0 ml of 100% alcohol/kg body weight. Subjects filled out a modified version of Rotter's locus of control scale and reported their perceptions to Street's Gestalt Completion Test. The latter test was scored in a standardized way for stimulus closeness, indicating a reality oriented and rational functioning, and stimulus distance, indicating a more primitive, irrational and pleasure oriented functioning. Alcohol made subjects less internally controlled and decreased the reality oriented functioning while the pleasure oriented functioning was not affected. Results were discussed in terms of pharmacological mechanisms, disinhibition, and creativity.
