Binge drinking is a social phenomenon with a high prevalence among undergraduate students. The College Alcohol Study (CAS) found that for a sample of 140 colleges in the United States, 44% of the responding students were binge (≥5/4 successive drinks/ounces for males and females, respectively) drinkers [1]. The neurocognitive effects of this pattern of alcohol intake have not been well studied, but the varied literature suggests several negative sequelae [2]. Although an empirical definition of binge drinking has not been used consistently, cognitive and behavioral studies generally have found frontal lobe and working memory deficits. Heavy social drinkers, defined to include those who engaged in binge drinking episodes, demonstrated delayed auditory and verbal memory deficits related to task difficulty that were absent for light social drinkers [3]. However, the discrepancies between social and binge patterns of alcohol consumption imply that these results should be cautiously extrapolated to the binge drinking population. Other neurocognitive impairments such as deficits in the Paced Auditory Serial Addition Test, executive planning function, episodic memory [4], spatial working memory, and pattern recognition task impairments also have
