  • 4

Objectives : The purpose of this study was to evaluate effects of alcohol on psycho - motor performance and subjective assessments in normal adults with high and low trait anxiety. Methods : The subjects consisted of 11 men in each group were tested with two doses of alcohol(0.25g/kg and 0.75g/kg). Blood alcohol concentration(BAC),psychomotor performance(critical flicker fusion threshold, CFFT ; choice reaction time, CRT) and subjective assessment were measured at pre-alcohol baseline and 20,40,80,and 160 minutes after intake of alcohol. Results : 1) There was no significant difference in BACs b etw een two groups at any time points after intake of each dose of alcohol. 2) After intake of 0.25g/kg alcohol, high anxiety group, compared to low anxiety group, reported less anxious and more relaxed feelings. In psychomotor performance test, however, there was no significant difference between the two groups. 3) After intake of 0.75g/kg alcohol, CFFT was increased in high anxiety group while it was decreased in low anxiety group. In subjective assessment, only high anxiety group tended to show more positive response. Conclusion : These results imply that alcohol may be more beneficia l in individuals with high trait anxiety than those with low trait anxiety in terms of objective performance and subjective feelings. Furthermore, these suggest that the alcohol benefits might contribute to drinking more alcohol and frequently in individuals with high trait-anxiety
