Abstract
Social drinking young men participated in an experiment exploring whether acute alcohol intoxication affects the characteristics of the psychological defence structure. It was found that a moderate alcohol dose (1.0 ml of 100% alcohol/kg body weight) increased the overall level of defence activity compared to a sober Control group and as measured by the Defence Mechanism Test. This increase was mainly due to a significant increase in the defence mechanism Isolation. Gender differences in this respect and the implications of this shift in the defence structure for the understanding of intoxicated behavior and motives for drinking were discussed.
