of sobriety varying from days to several years to each other or with a control group of healthy participants (e.g., Brandt et al., 1983; Hochla et al., 1982; Markowitsch et al., 1986; Munro et al., 2000; Reed et al., 1992). To assess within-subject change, longitudinal designs, retesting the same group of alcoholic patients and control participants at variable time intervals, are preferred (e.g., Fabian and Parsons, 1983; Glenn et al., 1994; Rosenbloom et al., 2004; Rourke and Grant, 1999; Yohman et al., 1985).
