study of these potentially important factors is warranted. As recommended by Morean and Corbin (2010), the use of standardized alcohol-administration procedures and risk-group categorization methods (e.g., binge drinking; Wechsler and Isaac, 1992)—along with validated measures of subjective stimulation and sedation (Martin et al., 1993; Ray et al., 2009) and placebo-controlled designs to rule out expectancy explanations—will speed advancements in this area.
