    Older adults did not use more efficient problem-solving strategies when faced with increased task difficulty. Task difficulty did not significantly impact problem-solving efficiency in either younger or older adults.

    Area of Science:

    • Cognitive psychology
    • Gerontology
    • Human development

    Background:

    • Older adults often exhibit changes in cognitive functions.
    • Problem-solving efficiency can be influenced by age and task complexity.

    Purpose of the Study:

    • To investigate if increased task difficulty enhances problem-solving strategies in older adults.
    • To compare problem-solving efficiency between younger and older adults under varying task difficulties.

    Main Methods:

    • Participants completed the Twenty Questions task with varying numbers of possible solutions (64 vs. 10,000).
    • Task difficulty was manipulated by the number of solutions and their physical presence.
    • Problem-solving efficiency was measured for both younger and older adult groups.

    Main Results:

    • Younger adults demonstrated greater efficiency than older adults in problem-solving.
    • No significant effect of increased task difficulty on problem-solving strategies was observed for either age group.
    • The physical presence of solutions did not alter problem-solving efficiency.

    Conclusions:

    • Increased task difficulty does not necessarily elicit more efficient problem-solving strategies in older adults.
    • Age remains a factor in problem-solving efficiency, independent of task difficulty.
    • Further research is needed to understand age-related cognitive strategies in complex problem-solving scenarios.
