Practicing kayak rolls with high contextual interference, or alternating sides, improved skill acquisition and retention compared to blocked practice. This suggests randomizing practice may optimize learning for new motor skills.

Area of Science:

  • Motor Learning
  • Sports Science
  • Kinesiology

Background:

  • Contextual interference (CI) involves altering practice order of similar motor tasks to enhance learning.
  • Previous research shows CI benefits skills like batting and serving.
  • Current kayak instruction often uses blocked practice for the Pawlata roll.

Purpose of the Study:

  • To investigate the efficacy of high contextual interference (HCI) for learning the kayak Pawlata roll.
  • To compare HCI with low contextual interference (LCI) based on current instructional recommendations.
  • To determine if HCI improves skill acquisition, retention, and transfer.

Main Methods:

  • 16 novice kayakers were randomly assigned to HCI (alternating sides) or LCI (one side to criterion) groups.

Related Experiment Videos

  • Participants learned the Pawlata roll skill.
  • Performance was assessed via retention and transfer tests after one week.

    • Main Results:

    • The HCI group acquired the Pawlata roll faster than the LCI group.
    • HCI led to quicker success in retention (full roll) and transfer (half roll) tests.
    • Acquisition was unexpectedly improved, not impaired, under HCI, suggesting enhanced bilateral transfer.

    Conclusions:

    • High contextual interference, involving randomized practice, is more effective for learning the kayak Pawlata roll than traditional blocked practice.
    • Current instructional methods advocating blocked practice may not be optimal for skill acquisition and retention.
    • Randomized practice may enhance bilateral transfer, leading to faster and more effective skill development.
