The reciprocal effects of leisure time activities and intellectual functioning in older people: a longitudinal analysis

Abstract

By using data from a representative longitudinal survey, the authors provide strong evidence that complex leisure time activities increase intellectual functioning for workers and nonworkers. Although the effects were relatively moderate, both the present article and its predecessor on the effects of paid work (C. Schooler. Mulatu, & Oates. 1999) showed that, even in old age, carrying out complex tasks has a positive effect on intellectual processes. In both cases, initially high levels of intellectual functioning led to high levels of environmental complexity, which in turn raised levels of intellectual functioning, thus providing a pathway contributing to the high correlation of intellectual functioning over a 20-year period in middle and late adulthood. The present findings indicate that even in old age carrying out substantively complex tasks builds the capacity to deal with the intellectual challenges such complex environments provide.
