When and how perceived control buffers against cognitive declines: A moderated mediation analysis.
Abstract
Although perceived control is a well-established predictor of cognitive aging, less is known about how and under what developmental circumstances these beliefs about personal influence may protect against cognitive declines. Our study examined light physical activity (LPA) as an unexplored mechanism that may link changes in two facets of perceived control (personal mastery, perceived constraints) to longitudinal trajectories of cognitive functioning. We also examined whether mediated pathways were moderated by age (i.e., differed across the adult lifespan). We analyzed two-wave, 9-year data from the national Midlife in the United States Study (

Research summary
The paper claims that light physical activity may mediate the relationship between perceived control and cognitive functioning across the adult lifespan. This research is relevant as it explores psychological and behavioral factors that could influence cognitive aging, potentially addressing root causes of cognitive decline rather than merely treating symptoms.
