the first involving multiple alcohol doses. Use of multiple doses is important as dosage is a key factor in subjective response (Morean and Corbin 2010; Schuckit et al. 1984). The use of lower risk social drinkers allows for investigation of relationships between impulsivity and subjective response to alcohol with minimal confounding by heavy alcohol exposure, which has been found to affect both subjective response to alcohol (Morean and Corbin 2008) and impulsive behavior (see Leeman et al. 2009).
