An existing-groups design was adopted comparing existing groups of ‘excessive’ alcohol users and low-dose/non-users. The participant group was a convenience sample of students studying at a college and a university in the northeast of England. No intelligence measures were administered in the study. Forty-five participants were identified as ’excessive alcohol users’ (28 females, 17 males; mean age 17.8 years (SD = 1.14, age range of 16–19 years)) ingesting above 21 and 14 units per week for males and females, respectively, over a period of one year or more. Sixty-three were identified as ’low-dose/no-alcohol controls’ (41 females, 22 males; mean age 16.8 years [SD = 1.13, age range of 16–19 years]) ingesting below the 21/14 units per week estimates over one year or more (incorporating nine nonusers). A U.K. unit (8 g ethanol) contains .343 U.S. fluid ounces of ethanol [6]. The mean alcohol consumption for the excessive alcohol user group was 27.2 units (9.33 U.S. ounces) per week (range = 20–50 units; SD = 7.90), and the mean alcohol consumption for the low-dose/no-alcohol group was 1.50 units (.51 U.S. ounces) per week (range = 0–4 units; SD = 1.34). The drinking participants reported being ‘drug free’ for at least 48 hours prior to testing and reported that they had never suffered from alcohol dependency or any form of clinical amnesia or depression. These latter checks were based on self-reports and no biological or clinical screening measures were used.
