Study: It’s Likely You Can’t Handle Your Alcohol As Well As You Think

If you think you’re a seasoned drinker who knows how to hold your alcohol– think again. University of Chicago researchers tested 155 young adult volunteers on two cognitive and motor coordination tests at the beginning of the study and again five years later. They found heavy drinkers, defined as a person who drank between 10 and 40 alcoholic drinks per week, may have less impairment in simpler fine motor skills relative to lighter drinkers, but the tolerance does not help performance on tasks involving more complex motor processing and short-term memory. They note that for heavy drinkers, lower self-perceived impairment and higher sensitivity to the stimulating and rewarding effects of alcohol could make the habit more dangerous for them. (EurekAlert!
