Distraction impairs working memory, especially in older adults. Task-irrelevant information disrupts attention and memory encoding, affecting goal-directed actions across age groups.

Area of Science:

  • Cognitive Psychology
  • Neuroscience of Aging

Background:

  • Working memory is crucial for cognitive tasks.
  • Selective attention filters information.
  • Aging can affect cognitive functions.

Purpose of the Study:

  • To investigate how taxing selective attention affects working memory.
  • To examine age-related differences in response to distraction.

Main Methods:

  • Two experiments were conducted.
  • Participants performed tasks under conditions with and without task-irrelevant information.
  • Performance metrics included efficiency and error types.

Main Results:

  • Task-irrelevant information disrupted working memory efficiency in both age groups.

  • This disruption was generally more pronounced in older adults.
  • Distraction increased intrusion errors (both groups) and memory-based errors (older adults).

    • Conclusions:

    • Distraction negatively impacts the maintenance of goal-directed thought and action.
    • Older adults show greater vulnerability to distraction's effects on working memory.
    • Distraction particularly affects encoding and retention in older adults.
