    This study explored semantic priming in adults, finding both young and older individuals benefit from automatic priming. However, older adults showed more errors on nonword trials during controlled priming.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Human Aging Research

    Background:

    • Semantic priming effects are crucial for understanding word recognition.
    • Investigating age-related differences in cognitive processes like priming is vital for understanding cognitive aging.

    Purpose of the Study:

    • To examine age differences in automatic and controlled semantic priming.
    • To analyze how varying prime probabilities affect young and older adults' performance.
    • To assess age-related variations in accuracy, response bias, and latency.

    Main Methods:

    • Lexical decision task with tachistoscopic parafoveal stimulus presentation.
    • Manipulation of valid prime probabilities to differentiate automatic and controlled priming.
    • Measurement of response latency, accuracy, and error patterns.

    Main Results:

    • Both age groups demonstrated benefits without costs in automatic priming.
    • Both groups exhibited benefits and costs under controlled priming conditions.
    • Older adults showed a higher error rate on nonword trials compared to young adults.

    Conclusions:

    • Age differences exist in controlled semantic priming, particularly in error patterns.
    • Older adults may exhibit distinct error tendencies in lexical decision tasks.
    • Understanding these age-specific priming effects can inform cognitive aging research.
