Random practice, where skills are mixed, improves motor learning more than blocked practice. However, this benefit may disappear with more extensive skill transfer tasks in children.

Area of Science:

  • Motor Learning
  • Motor Skill Acquisition
  • Cognitive Psychology

Background:

  • The contextual interference effect suggests random practice enhances motor skill learning compared to blocked practice.
  • This effect has been consistently observed in various motor tasks and populations.
  • Understanding the boundaries of this effect is crucial for optimizing motor skill development.

Purpose of the Study:

  • To investigate the contextual interference effect in children performing a linear positioning task.
  • To determine if the contextual interference effect persists in extended transfer trials.
  • To examine the impact of practice schedules on motor skill retention and transfer.

Main Methods:

  • A study involving 57 children (24 boys, 33 girls, mean age 10.5 years) was conducted.

  • Participants were randomly assigned to either a random practice or blocked practice group.
  • A linear positioning motor task was used to assess motor skill learning, retention, and transfer.

    • Main Results:

    • The contextual interference effect was initially observed, with random practice outperforming blocked practice.
    • However, this effect appeared to diminish or dissipate during extended transfer trials.
    • This suggests that the benefits of random practice may be context-dependent or change over time.

    Conclusions:

    • The findings indicate that the contextual interference effect may not be universally robust, particularly in later stages of skill acquisition.
    • Extended practice or transfer may alter the relative effectiveness of random versus blocked practice schedules.
    • Further research is needed to explore the factors influencing the persistence of the contextual interference effect in pediatric motor learning.
