Discontinuity in cognitive skill.

P A Kolers, R L Duchnicky

    Journal of Experimental Psychology. Learning, Memory, and Cognition
    |October 1, 1985
    PubMed
    Summary
    This summary is machine-generated.

    Learning to read transformed text improves with practice. While skill acquisition is continuous, its expression is discontinuous, likely due to task segmentation.

    Area of Science:

    • Cognitive psychology
    • Perceptual learning

    Background:

    • Reading skill for geometrically transformed text improves with practice.
    • Continuity of learning implies skill improvement within pages, not just across them.

    Purpose of the Study:

    • Investigate the continuity of skill acquisition in reading transformed text.
    • Differentiate between continuous skill acquisition and discontinuous skill expression.

    Main Methods:

    • Compared performance within pages versus between pages.
    • Manipulated text presentation timing and quantity.
    • Reanalyzed published data and conducted three new experiments.

    Main Results:

    • Skill acquisition was found to be continuous with practice.

    Related Experiment Videos

  • Skill expression, however, was observed to be discontinuous.
  • Performance varied based on presentation timing and text quantity.

    • Conclusions:

    • Skill acquisition in reading transformed text is a continuous process.
    • Skill expression appears to require perceptual segregation into task units.
    • Competence develops strictly as a function of practice.
