Demographics for the ALC and NC groups are presented in Table 1. The ALC and NC groups did not differ in age, but ALC had fewer years of formal education than NC. NART scores [National Adult Reading Test; (Nelson, 1982)] were available for a subset of participants and showed a modestly lower estimated premorbid IQ for ALC than NC. ALC endorsed a greater number of depressive symptoms (Beck et al., 1996), scored lower on a general cognitive screening test (Mattis, 2004), and had lower socioeconomic status (Hollingshead, 1975) than NC. As expected, the ALC group had higher lifetime alcohol consumption.
