title: Pretest expectancies and cognitive impairment in alcoholics.
abstract: Alcoholics' neurological deficits have been attributed to cognitive impairment associated with brain dysfunction. Because alcoholics perceive themselves as impaired in higher cognitive functions, we investigated the alternative hypothesis that their deficits are predicted by lowered expectancies for successful performance. Ss were 48 male, middle-aged Veterans Administration inpatient alcoholics and 36 community controls. Subjects completed a standard series of neuropsychological tests. Before taking each test, Ss were asked how well they expected to do on that test in relation to members of their community. As predicted, means for the overall measures of expectancies and performance were significantly lower for alcoholics than for control Ss. Although expectancies were significantly correlated with performance, regression analyses indicated they could not account for the obtained performance differences.
