ABSTRACT Introduction: Given evidence that activity engagement in older adulthood can have protective effects on the aging brain, we investigated the idea that volunteering in the community, which often encompasses social, cognitive, and physical activity, might benefit cognition. Method: Ninety-one retired 65- to 75-year-olds reported their sociodemographic characteristics, wellbeing, volunteering, and activity engagement. They also completed computerized cognitive tests that tapped specific functions known to decline disproportionately with age. Results: Volunteering at least monthly was associated with better working memory and more social and cognitive activity. Mediation analyses indicated that volunteering was indirectly related to switching performance via cognitive activity. However, the volunteering-working memory association did not depend on activity engagement, leaving the underpinning mechanisms unclear. Conclusions: These findings provide new insight into positive associations between older people’s volunteering, activity engagement, and cognitive functioning. However, further work is needed to understand the mechanisms that drive volunteering-cognition links, and to establish causality. 相似文献

According to an intuitive claim, in saying that one sees a picture's subject, i.e., what a picture presents, in the picture's vehicle, i.e., the picture's physical basis, by ‘in’ one does not mean the spatial relation of being in, as holding between such items in the real space. For the picture's subject is knowingly not in the real space where one veridically sees the picture's vehicle. Some theories of pictorial experience have actually agreed with this intuition by claiming that the picture's subject lies in a pictorial space of its own, disconnected from the real space that includes the picture's vehicle. Yet, not only linguistic evidence suggests that when used as above, ‘in’ means precisely that very relation, but an appropriate theory of pictorial experience can justify the above claim. 相似文献
