(estimated using age, gender, height, and weight) and the duration of the drinking period (15 min), using published formulas (see Curtin & Fairchild, 2003; Watson, 1989).

After drinking, participants sat idle for 15 min, which in the alcohol condition allowed the alcohol to begin absorption into the blood.
