Hypothesis
Changes in light physical activity may link perceived control to cognitive aging trajectories.
Conclusion
The study found that perceived control influences cognitive decline through changes in light physical activity, especially in older adults.
Supporting Evidence
- Changes in personal mastery and perceived constraints predicted changes in light physical activity.
- Changes in light physical activity predicted changes in episodic memory and executive functioning.
- The mediated pathways were strongest in old age for episodic memory.
Takeaway
Feeling in control can help keep your brain healthy as you get older, especially if you stay active.
Methodology
The study used autoregressive mediation and moderated-mediation models to analyze 9-year data.
Participant Demographics
