Abstract
This study examined the effects of acute alcohol ingestion and prior success or failure upon cognitive performance of 40 healthy, non-alcoholic subjects, during both the ascending and descending limbs of the blood alcohol curve. Measures of physiological arousal were made with frontal/laryngeal electromyographic and skin conductance response level parameters. Major findings were: (1) cognitive performance was impaired by alcohol ingestion; (2) autonomic arousal was significantly greater after alcohol than after placebo; (3) number and amplitude of skin response were greater on the ascending than on the descending limb; (4) the anticipated effects of failure on cognitive performance were ameliorated by alcohol; and (5) differential effects of alcohol on the psychophysiological parameters were demonstrated.
