Sixty-four healthy males between the age of 18 and 25 (mean age = 20.51 years, SD = 1.99) were recruited to participate in this study. Participants were recruited from the undergraduate population of the Erasmus University in Rotterdam and by posting weblogs on social network sites. Screening measures were conducted to determine medical history and took place by telephone. Inclusion criteria were the absence of a current medical, neurological, or psychiatric condition, and no current use of medication during the past 4 weeks before the experimental session. Participants were not included in the study if they had a self-reported history of alcohol-related problems. The median frequency of drinking days was 9 to 11 days each month, and the median quantity of drinks on each occasion was six glasses. The median age of drinking onset was between 14 and 15 years.
