Solution shift performance in the elderly

C J Rogers, B J Keyes, B J Fuller

    Journal of Gerontology
    |November 1, 1976

    Summary
    This summary is machine-generated.

    Elderly adults sometimes solve concept problems dimensionally, but stimulus materials impact performance. Rigidity does not explain their difficulties with solution shifts, suggesting alternative factors are at play.

    Area of Science:

    • Cognitive Psychology
    • Developmental Psychology
    • Gerontology

    Background:

    • Cognitive abilities can change with age.
    • Understanding cognitive shifts in elderly adults is crucial for addressing age-related cognitive decline.
    • Previous research on cognitive flexibility in older adults has yielded mixed results.

    Purpose of the Study:

    • To investigate how elderly adults solve concept problems with different solution shifts (reversal and nonreversal).
    • To examine the influence of various stimulus materials (compact designs, distributed designs, distributed foods) on cognitive task performance in the elderly.
    • To explore the underlying reasons for difficulties elderly adults face when shifting solutions in cognitive tasks.

    Main Methods:

    • A concept problem task was administered to 72 elderly adults.

  • The task involved two types of solution shifts: reversal and nonreversal.
  • Stimulus materials were varied, including compact designs, distributed designs, and distributed foods.

    • Main Results:

    • Stimulus materials significantly affected postshift performance in elderly participants.
    • Elderly adults demonstrated dimensional responding under specific circumstances.
    • Analysis indicated that a 'rigidity' explanation does not account for the observed difficulties in shifting solutions.

    Conclusions:

    • Cognitive performance in elderly adults is influenced by the nature of stimulus materials.
    • The elderly can exhibit dimensional responding, challenging simplistic notions of cognitive inflexibility.
    • Alternative explanations beyond rigidity are needed to understand cognitive shifting challenges in older adults.
