Remembering to remember: adult age differences in prospective memory

T Mäntylä1

Summary

Older adults show greater prospective memory decline than younger adults, especially with complex tasks. Task difficulty, particularly with atypical memory cues, significantly impacts age-related differences in prospective memory performance.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human Development

Background:

  • Prospective memory, the ability to remember future intentions, is crucial for daily functioning.
  • Age-related cognitive changes can impact prospective memory, but the extent and underlying mechanisms require further investigation.

Purpose of the Study:

  • To investigate age-related differences in prospective memory.
  • To examine how task complexity, specifically the typicality of target words, influences prospective memory performance in younger and older adults.

Main Methods:

  • A laboratory-based free-association task was employed.
  • Participants (younger and older adults) performed specific actions upon encountering target words (typical or atypical semantic category instances).
  • Self-initiated retrieval demands were manipulated via target word typicality.

Main Results:

  • Age differences in prospective memory were amplified with atypical target words and reduced with typical targets.
  • Younger adults outperformed older adults in both remembering when to act and what action to perform.
  • Performance decrements were more pronounced in older adults under higher task complexity.

Conclusions:

  • The magnitude of age-related differences in prospective memory is influenced by task complexity.
  • Prospective memory failures are exacerbated in tasks demanding significant self-initiated retrieval operations, particularly for older adults.
