    Older adults performed similarly to younger adults on information-processing tasks when using strategies that minimized processing demands. However, age-related disadvantages emerged with more complex strategies.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience of Aging
    • Human Information Processing

    Background:

    • Cognitive aging research explores how information processing abilities change with age.
    • Understanding age-related differences in cognitive strategies is crucial for interventions.

    Purpose of the Study:

    • To compare information-processing strategies and performance between old and young adults.
    • To identify how different cognitive strategies impact age-related performance differences.

    Main Methods:

    • Matched groups of old and young adults completed two information-processing tasks: rotated figures and sentence verification.
    • Reaction times and verbal reports were analyzed to identify cognitive strategies employed.
    • Participants' strategy selection and task performance were compared across age groups.

    Main Results:

    • The distribution of strategy use was similar between old and young adults.
    • Age differences in performance varied depending on the strategy used.
    • Older adults showed minimized age-related disadvantages when using processing-reducing strategies.

    Conclusions:

    • Older adults can effectively utilize strategies that reduce cognitive load, performing comparably to younger adults.
    • Cognitive strategies imposing higher processing demands or memory load exacerbate age-related performance deficits.
