The effect of alcohol consumption on risk-taking while driving.

Using a cover story of the effects of alcohol on perceptual and motor abilities, three levels of alcohol consumed (high, moderate, and none) were combined with three levels of alcohol expected (high, moderate, and none) to determine their effects on risk-taking while driving. Thirty-nine subjects were randomly assigned to six conditions. A driving simulation task was employed; dependent variables were cars passed and total time at high speed. Results indicated greatest risk-taking, measured by cars passed and time spent at high speed, by subjects who believed they had consumed a moderate amount of alcohol. Actual amount of alcohol consumed produced no significant differences.
