    Memory codification explains word superiority and repetition effects in item identification. Pseudoword codes become as permanent as word codes after learning, suggesting strong memory retention.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Human Memory

    Background:

    • The word superiority effect demonstrates faster word identification than pseudoword identification.
    • The repetition effect shows that prior item exposure enhances subsequent identification.

    Purpose of the Study:

    • Investigate memory processes behind word superiority and repetition effects.
    • Examine codification development and retention for pseudowords.
    • Analyze the growth and decay of the repetition effect for words and pseudowords.

    Main Methods:

    • Threshold identification tasks were used to assess accuracy.
    • Repetition effects were studied across different presentation spacings and delays (including one year).
    • A computational model of identification was developed and tested against the data.

    Main Results:

    • Codification of pseudowords was complete after approximately five repetitions, matching word identification accuracy.
    • The repetition effect decayed significantly over time, particularly after one year, suggesting an episodic memory basis.
    • Learned pseudoword codes demonstrated comparable strength and permanence to word codes after one year.

    Conclusions:

    • Codification underlies both word superiority and repetition effects.
    • The repetition effect relies on episodic memory, which is subject to forgetting over long delays.
    • Learned memory codes for words and pseudowords are similarly robust and long-lasting.
