Daily increases in perceived control may boost episodic memory, especially for individuals with lower income. This research highlights the link between daily control and cognitive function in at-risk populations.
Area of Science:
- Psychology
- Neuroscience
- Gerontology
Background:
- Long-term perceived control is linked to cognitive function.
- Little is known about daily fluctuations in control and their impact on cognition.
- Socioeconomic differences in this relationship are understudied.
Purpose of the Study:
- To investigate the link between daily changes in perceived control and episodic memory.
- To determine if socioeconomic status (income, education) moderates this association.
- To explore micro-longitudinal effects on cognition in middle-aged and older adults.
Main Methods:
- Analyzed 14-day measurement-burst data from 208 adults (aged 30-81).
- Utilized multilevel models to examine within-person associations.
- Assessed daily perceived control and episodic memory performance.
Main Results:
- Daily increases in perceived control showed a trend towards positive association with episodic memory.
- This association was significant for individuals with lower income.
- No significant moderation by education level was found.
Conclusions:
- Micro-longitudinal increases in perceived control are associated with dynamic changes in daily cognition.
- The link between daily control and episodic memory is more pronounced for lower-income individuals.
- Findings contribute to lifespan development theories, particularly for socioeconomic groups vulnerable to cognitive decline.
