    Both young and elderly adults benefit from the generation effect, a memory enhancement strategy. However, older adults showed delayed recall improvement in free recall tasks.

    Area of Science:

    • Cognitive Psychology
    • Developmental Psychology
    • Neuroscience

    Background:

    • The generation effect is a well-documented mnemonic phenomenon where recalling information enhances memory recall.
    • Developmental differences in cognitive strategies and memory performance are observed between younger and older adults.

    Purpose of the Study:

    • To investigate developmental differences in the generation effect between young and elderly adults.
    • To assess the efficacy of internal stimulus generation as a mnemonic device across different age groups.

    Main Methods:

    • Participants (young and elderly adults) engaged in tasks requiring synonym or rhyme generation of stimulus words.
    • Two memory retention tasks were employed: multiple-trial free recall and a 48-hour delayed recognition task.

    Main Results:

    • A significant generation effect was observed in both young and elderly adults across both retention tasks.
    • Elderly participants demonstrated a delayed emergence of the generation effect in free recall, appearing by the second or third trial.

    Conclusions:

    • Internal stimulus generation serves as a potent mnemonic device for both young and elderly individuals.
    • Age-related differences exist in the immediate application of the generation effect, particularly in free recall tasks.
