    Older adults show age-related slowing in memory search tasks with mixed categories. This slowing disappears when stimuli are categorically distinct, supporting the complexity hypothesis of cognitive aging.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Human Aging Research

    Background:

    • Cognitive aging research investigates age-related changes in mental processes.
    • Memory search tasks are crucial for understanding information processing speed and efficiency.
    • Previous studies suggest age-related cognitive slowing, but the underlying mechanisms require further elucidation.

    Purpose of the Study:

    • To examine the impact of categorical information on memory search performance in older and younger adults.
    • To test the complexity hypothesis of age-related cognitive slowing.

    Main Methods:

    • Participants (old and young adults) performed a memory search task with varying set sizes (2-4 items).
    • Stimulus sets were either categorically mixed or categorically distinct.

  • Response times and accuracy were recorded to assess search rates.

    • Main Results:

    • A significant set size effect was observed in both age groups for categorically mixed stimuli, with older adults exhibiting slower search rates.
    • When stimuli were categorically distinct, search rates did not differ between age groups, and the set size effect was eliminated.
    • Older adults' response times were a monotonic function of younger adults' response times across conditions.

    Conclusions:

    • Categorical organization significantly influences age-related differences in memory search.
    • The findings support the complexity hypothesis, suggesting that task complexity, influenced by categorical structure, drives age-related slowing.
    • Interventions or task designs that simplify categorical processing may mitigate age-related cognitive deficits.
