 Lifestyle Variables That Affect Intellectual Functioning

Show Summary Details


The Life Complexity Inventory (LCI) has been used since 1974 to characterize the microenvironment of participants in the Seattle Longitudinal Study. Early analyses of this instrument identified eight lifestyle factors that were related to measures of intellectual abilities. Low-to-modest positive correlations were found between amount of leisure activity and levels of cognitive functioning. Positive lifestyle characteristics were also correlated with high levels of cognitive functioning, with the dimensions of prestige, social status, and work characteristics showing the highest correlations. This chapter discusses lifestyle variables that affect intellectual functioning. Family similarity in lifestyles was examined for parent-offspring and sibling dyads, along with the effects of work characteristics and retirement on cognitive functions.
