Aging impairs source memory more than item memory. Semantic clustering encoding strategies can improve memory performance in older adults, suggesting a link between semantic knowledge and memory decline.

Area of Science:

  • Cognitive Psychology
  • Neuroscience of Aging
  • Human Memory

Background:

  • Aging is associated with memory deficits, particularly in source memory attribution.
  • Reduced use of encoding strategies contributes to memory decline in older adults.

Purpose of the Study:

  • To investigate the impact of encoding strategy manipulation on item and source memory in young and elderly individuals.
  • To examine age-related differences in semantic clustering and its relation to memory performance.

Main Methods:

  • Participants: 32 young and 68 elderly adults (dichotomized into young-old and old-old based on age 74).
  • Memory Assessment: California Verbal Learning Test (CVLT) Word List A and its alternate form.
  • Encoding Manipulation: Semantic clustering (Blocked List) versus intermixed categories (Unblocked List).

  • Memory Judgments: Assessed 20 minutes and one week post-acquisition.

    • Main Results:

    • Older adults showed a disproportionate decline in source memory compared to item memory.
    • Semantic blocking improved item memory in elders but not in the young.
    • Elderly participants exhibited reduced semantic clustering with age, which positively correlated with source memory performance.

    Conclusions:

    • Source memory is more vulnerable to age-related decline than item memory.
    • Semantic clustering is a beneficial encoding strategy for enhancing memory in older adults.
    • Age-related changes in semantic knowledge may underlie declines in clustering and overall memory performance.
