from Part II - Mechanisms of Cognitive Aging
Published online by Cambridge University Press: 28 May 2020
This chapter considers ways that perceived time – both at the level of seconds and lifetimes – may influence adult development. Research suggests that age-related impairments in divided attention contribute to older adults’ underestimation of short-term duration judgments. A separate literature suggests that perceived constraints on future time lead to the prioritization of emotionally meaningful goals. We consider ways that these two research streams may inform one another. Findings about duration judgments may help to explain age-related time acceleration that affects perceptions of the future. Findings about motivational changes associated with perceived constraints on time may influence attention in ways that reduce accuracy of duration judgments. We urge joint consideration of these literatures in hypothesis generation about developmental trajectories of cognitive processing, motivation, and emotional well-being.
