    Processing efficiency in children and adults shows complex developmental changes. Name-match decisions improved with age, but physical-match interference persisted, impacting older children and adults.

    Area of Science:

    • Cognitive Psychology
    • Developmental Psychology
    • Human Information Processing

    Background:

    • Information processing efficiency evolves throughout childhood.
    • Understanding developmental changes in decision-making is crucial for cognitive science.

    Purpose of the Study:

    • To investigate age-related differences in information processing efficiency.
    • To examine how children and adults process visual and semantic information.

    Main Methods:

    • Participants (8, 10, 12 years, and adults) performed rapid same/different judgments on line drawings.
    • Judgments were based on physical appearance (physical match) or name (name match).
    • Reaction times measured processing efficiency, including interference effects.

    Main Results:

    • Different judgments took longer than same judgments for children, decreasing with age.
    • Name-match judgments were slower than physical-match judgments, with inconsistent age-related changes.
    • Interference from irrelevant physical information in name-match tasks decreased with age.
    • Interference from irrelevant name information in physical-match tasks remained significant for older children and adults.

    Conclusions:

    • Cognitive processing efficiency shows complex developmental trajectories.
    • Age impacts the ability to ignore irrelevant information differently depending on the task.
    • Developmental changes in information processing are not uniform across all cognitive tasks.
