Abstract
This experiment investigated the effects of alcohol ingestion on
three measures of human performance: (a) information processing
time, (b) reaction time and (c) movement time. The relationship
between the alcohol effects and the drinking history of the subjects
was also examined in order to determine the existence of any alcohol
adaptation. In addition, the influence of alcohol on manifest anxiety
was investigated. The analyses of variance and correlation analysis
which were performed showed that dosage had a significant effect on
information processing time and reaction time but had no significant
effect on movement time. The rate of ingestion, except at the highest
rate of 3 oz/35 min, did not significantly contribute to the effects
of dosage. There was no significant correlation between alcohol
effects and drinking history or manifest anxiety changes. The results
of this study indicate that, even at small dosages, alcohol has a great
effect on cognitive ability. It was also shown that alcohol effects
psychomotor performance to a lesser degree and has little effect on
neuromuscular performance.
