| Abstract: | Choice reaction time and serial learning tasks were studied in three groups of elderly men (aged 65 to 85), including (a) hospitalized veterans, (b) veteran outpatients, and (c) nonhospitalized veteran volunteers. Demographic variables, life satisfaction, and attitudes toward aging, as well as objective and subjective measures of physical impairment, were assessed in each group. The three groups differed on both reaction time and serial learning measures. Multivariate analysis revealed that objective physical health assessments were the best predictors of reaction time performance, whereas subjective assessments best predicted serial learning performance. More negative attitudes and life satisfaction were associated with impaired physical health, but these psychosocial measures were poor predictors of behavioral performance. |
