Adult age differences in recognition memory for a nonsemantic attribute

D H Kausler, J M Puckett

    Experimental Aging Research
    |August 1, 1980
    PubMed
    Summary

    Older adults show memory deficits not only for word meaning but also for word case. This suggests that encoding word case is an effortful cognitive process, not automatic.

    Area of Science:

    • Cognitive psychology
    • Neuroscience of aging
    • Human memory research

    Background:

    • Adults commonly exhibit age-related deficits in recognizing word content.
    • The generalizability of these deficits to nonsemantic attributes is not well understood.
    • Case format (upper vs. lower) is a nonsemantic word attribute.

    Purpose of the Study:

    • To investigate whether age-related memory deficits extend to the recognition of word case.
    • To determine if encoding of nonsemantic attributes like word case is an automatic or effortful process.
    • To compare young and elderly adults' performance on word content and case recognition tasks.

    Main Methods:

    • Participants: Young adults and elderly adults.
    • Task: Recognition memory for word content and word case (upper vs. lower) after study list presentation.
    • Analysis: Comparison of recognition scores between age groups and between tasks.

    Main Results:

    • Both young and elderly adults performed significantly above chance on case recognition.
    • Elderly adults exhibited lower recognition scores than young adults for case alone.
    • Elderly adults also showed lower recognition for word content combined with case compared to young adults.

    Conclusions:

    • Age-related deficits in memory extend to the recognition of nonsemantic attributes like word case.
    • Encoding of word case is not an automatic memory process.
    • Case encoding appears to involve cognitively effortful processes sensitive to aging.
