Technical Abstract: Few studies have examined the impact of alcohol hangover on performance. In the present placebo-controlled study, 19 college-aged males were administered either 2.0 mL/kg of 100-proof vodka (10 subjects) or a placebo (9 subjects) in 3 equal-sized drinks during a 60-min period. Ten minutes after subjects finished drinking, average breath alcohol level (BAL) was 0.061 in treated subjects. Four hours later, subjects were administered the Digit Span, Digit Symbol and Letter-Number subtests from the WAIS-III, and an 18-min tracking task to measure eye-hand coordination. BAL after 4 hours was 0.022. No significant group differences were observed on any of the WAIS-III subtests. However, subjects who had received alcohol performed significantly worse (less time on target; p<0.05) than placebo subjects during the tracking task when configured for greatest difficulty (target moved at high speed in a counterclockwise circular direction). The results suggest that hangover can produce significant impairment under heavy task demands.
