Older adults showed lower memory performance than younger adults, and activity levels did not fully close this age-related memory gap. Vocabulary remained a key predictor of memory across both age groups.

Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Gerontology

Background:

  • Age-related cognitive decline is a significant concern.
  • Understanding factors influencing memory performance in aging is crucial.

Purpose of the Study:

  • To investigate the relationship between physical and social activities and memory performance in young and old adults.
  • To determine if activity levels can account for age-related differences in memory.

Main Methods:

  • Participants: Young and old adults.
  • Measures: Vocabulary test, Activities Frequency Inventory (AFI), Activity Preference Scale (APS), and everyday memory tests.
  • Analysis: Comparison of memory performance between age groups and activity levels, regression analyses.

Main Results:

  • Young adults outperformed old adults on memory tests.
  • Higher activity preference (APS) in young adults and higher activity frequency (AFI) in old adults correlated with better memory.
  • The age gap in memory performance persisted even when comparing active older adults with inactive young adults.
  • Activity measures did not significantly improve memory prediction beyond vocabulary scores.

Conclusions:

  • While activity engagement is associated with better memory, it does not eliminate age-related memory deficits.
  • Vocabulary knowledge is a robust predictor of memory performance across the lifespan.
  • Further research is needed to explore other factors contributing to memory differences in aging.
