Effects of Alcohol on Psychomotor Performance of Women: Interaction With Menstrual Cycle

The effects of alcohol on performance were investigated in 10 ovulating young women. Placebo drink and three doses of alcohol were administered in a random order both during follicular and luteal phases of the menstrual cycle. The women had significantly slower verbal information processing rate and poorer visual detection performance during the follicular than the luteal phase of the menstrual cycle. In psychomotor tasks other than tracking, dose--response relationships of alcohol were different during the different phases of the menstrual cycle.
