College students (mean age 25), who evidenced vasoconstriction or vasodilation after consuming alcohol (blood alcohol concentrations of 0.04-0.06%), completed 4 motor tasks (simple and complex reaction time, fast and slow turning) after drinking alcohol or a placebo. Vasodilators were significantly faster than vasoconstrictors on a complex reaction time task, but slower than vasoconstrictors when asked to turn a dial as rapidly as possible and when asked to turn a dial as slowly as possible. These differences did not depend on the subject having consumed alcohol at the time of the task; performance differences between vasoconstrictors and vasodialtors were observed after both alcohol and placebo. Performance differences between those who evidence vasoconstriction or dilation after consuming alcohol depend on the tasks employed to assess the differences.
