Ninety-six healthy adults (49 women), all white/non-Hispanic, ages 21–36 years (M = 23 years, SD = 3), were recruited from the Columbia, MO community using mass email announcements and advertisements in local periodicals. Eligibility was determined using a structured telephone interview. Individuals indicating any condition that would contraindicate alcohol administration (pregnancy; abstention; symptoms of alcohol or drug dependence; history of serious mental or physical illness; prescription medication other than oral contraception) or who reported history of head trauma or neurological disorder were excluded from the sample, as were individuals who reported drinking less than an average of 2 or more than an average of 25 drinks per week in the past three months. Eligible participants were scheduled for lab appointments and instructed to abstain from alcohol and other drugs for 24 hours prior and to eat a light meal 4–6 hours prior to their appointment. All lab sessions began between 12:00-4:00 pm. Affidavits completed upon arrival at the lab were used to ensure participants’ compliance with pre-session protocols and maintenance of study eligibility since the interview. Participants were compensated $12/hour for their time.
