Binge-groups consisted of male/female alcohol drinkers that were non-binging (>1 but <5/4 alcoholic drinks/ounces within 2 hours and occurring within the past 6 months), low-binging (5/4–7/6 drinks/ounces within 2 hours on more than 1 occasion within the past 6 months), and high-binging (≥10 drinks/ounces within 2 hours on more than 1 occasion within the past 6 months). Equal numbers of each sex and n = 16 in each binge group were obtained (total N = 96). Participants were matched on educational level, handedness, and demographic background. Participants were instructed to refrain from any alcohol consumption and drug use for at least 48 hours prior to testing.
