Verbal fluency and figural fluency in bright children.

R W Evans, R M Ruff, C T Gualtieri

    Perceptual and Motor Skills
    |December 1, 1985
    PubMed
    Summary

    Intellectually bright children and adults show age-related improvements in verbal and figural fluency. Motor speed affects figural fluency, but age differences remain significant, suggesting unique developmental trajectories for cognitive abilities.

    Area of Science:

    • Cognitive Psychology
    • Developmental Psychology
    • Neuroscience

    Background:

    • Previous research indicates age-dependent performance on fluency tasks.
    • Understanding cognitive development in intellectually bright individuals is crucial.

    Purpose of the Study:

    • To assess verbal and figural fluency in intellectually bright children and adults.
    • To investigate the influence of age and motor speed on fluency measures.
    • To evaluate a new figural fluency task's reliability and validity.

    Main Methods:

    • Participants included intellectually bright children (Grades 2, 4, 6) and adults.
    • Measures included verbal fluency and a novel figural fluency task.
    • Analysis of covariance was used to control for motor speed.

    Main Results:

    • Age-dependent performance was observed on both verbal and figural fluency tasks.
    • Motor speed partially accounted for performance differences on the figural task, but age effects persisted.
    • Results suggest distinct developmental patterns for verbal and figural fluency in bright individuals.

    Conclusions:

    • The new figural fluency task shows promise as a valid measure.
    • Age-related improvements in fluency differ between intellectually bright and average individuals.
    • Further research is warranted on age and IQ influences on cognitive fluency.
