The questions under consideration concern quantitative and qualitative aspects of the relationship between cognitive abilities and behavioral competences in the elderly institution residents. The former was assessed by an array of five cognitive measures, namely, two Piagetian tasks, Set Test, WAIS Vocabulary and Digit Span subtests and the WMS Associative Learning subtest and the latter by the Stockton Geriatric Rating Scale (SGRS). The overall variance in common between the two sets of variables was approximately 70 percent. Of the cognitive tasks, those most highly predictive of behavioral competences were the Piagetian tasks, Set Test and, to a lesser extent, WAIS Vocabulary subtest. Of the four SGRS factors, that predicted to the greatest extent was apathy, with physical disability to a lesser extent.
