The effects of alcohol-taking on performances of cognitive tasks were analyzed and possible influences on cardriving were discussed. Subjects were participated in psychological experiments which assessed their cognitive performances before and after taking alcohol. Three types of tasks were employed; 1) Simple Reaction Task (SRT), 2) Motion extrapolation task (MET) and 3) Combined task of SRT and MET. In SRT, subjects required to press a key when visual target appeared anywhere on display. In MET, subjects extrapolated arrival times of invisible moving target. Although the amount of alcohol taken by the subjects was relatively small (Beer [5% of alcoholic content] 500ml), subject's cognitive performances were damaged after drinking. Especially, performances of combined task, in which subjects executed SRT and MET simultaneously with different visual targets, were much lowered. These results suggested that alcohol-taking impaired attention, and subjects might have difficulties to share cognitive resources between two tasks under drinking situation. Perhaps this might be the reason why driving after drinking is risky in most cases.
