Summary
Two experiments designed to test the effects of alcohol on suppression of bar pressing are reported. In Experiment I, a modified version of the conditioned suppression technique was employed. The results showed that alcohol facilitated bar-pressing both prior to and after the introduction of a fear-inducing stimulus. Experiment II was designed to test the possibility that alcohol had facilitated bar-pressing prior to the buzzer in Experiment I by reducing fear which had generalized to the entire situation. As no emotional conditioning procedures were used at all, there was no possibility of such generalization. Yet, the effects of alcohol were the same in Experiment II as in Experiment I. It was concluded that the action of alcohol here could not be interpreted within a fear-reduction framework.
