Retrieval of information from long-term memory.

J R Anderson

    Science (New York, N.Y.)
    |April 1, 1983
    PubMed
    Summary

    Retrieval time from long-term memory depends on concept network activation. Fan effects, which slow retrieval, are reduced by overlearning or changing judgment tasks.

    Cognitive psychology·2001

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Information Processing

    Background:

    • Long-term memory stores information as interconnected concept networks.
    • Information retrieval involves spreading activation through these networks.
    • Retrieval time is influenced by activation levels and network pathways.

    Purpose of the Study:

    • To investigate the relationship between memory network structure and information retrieval time.
    • To examine the impact of 'fan effects' on retrieval efficiency.
    • To identify strategies for mitigating fan effects in memory recall.

    Main Methods:

    • Utilized a spreading activation model to simulate memory retrieval.
    • Analyzed the influence of fan effects (multiple pathways from a node) on activation dissipation.
    • Compared retrieval times across different learning and task conditions (overlearning, recognition vs. consistency judgments).

    Main Results:

    • Retrieval time increases with the number of pathways (fan effect) due to activation dissipation.
    • Overlearning the material significantly reduces fan effects.
    • Shifting from recognition to consistency judgments also mitigates fan effects.

    Conclusions:

    • Memory retrieval efficiency is constrained by the fan effect, where activation spreads thinly across multiple associations.
    • Cognitive strategies like overlearning and task modification can enhance memory recall by overcoming fan effects.
    • Understanding network dynamics is crucial for optimizing information access from long-term memory.
