    Area of Science:

    • Child development
    • Motor control research

    Background:

    • Fine motor skills develop throughout childhood.
    • Understanding developmental changes in motor control is crucial.

    Purpose of the Study:

    • To investigate the relationship between age and fine motor control in children.
    • To examine if skeletal maturity correlates with motor task performance.
    • To determine the underlying mechanisms of motor skill improvement with age.

    Main Methods:

    • Sixty children aged 5, 7, and 9 years participated.
    • A reciprocal tapping task was used to measure movement time, analyzed using Fitts' Law.
    • Hand-wrist X-rays were performed to assess skeletal age.

    Main Results:

    • No significant correlation was found between fine motor task performance and skeletal age.
    • Movement time improved with age in the tapping task.
    • Improvement in motor control was attributed to enhanced movement planning rather than increased arm speed.

    Conclusions:

    • Motor skill development in children is linked to cognitive planning abilities.
    • Skeletal maturity is not a primary determinant of fine motor skill performance in this age range.
    • Age-related improvements in motor tasks are driven by predictive control mechanisms.
