Motor schema formation and retention in young children

Area of Science:

• Motor Learning
• Motor Skill Acquisition
• Cognitive Psychology

Background:

• Schmidt's (1975) motor schema theory posits that variability of practice enhances motor schema formation.
• Understanding how practice variations influence motor skill learning and long-term retention is crucial for effective training.
• Previous research has explored motor learning principles, but further investigation into the variability-of-practice hypothesis is warranted.

Purpose of the Study:

• To test the variability-of-practice hypothesis regarding motor schema formation.
• To examine motor schema retention after a 2-week interval.
• To investigate the impact of varied practice on transfer of learning to novel tasks.

Main Methods:

• Preschool children participated in a bean bag tossing task over five days (100 trials total).
• Four groups received practice with varying bean bag weights to manipulate practice variability.
• Performance was assessed using criterion and novel weighted bean bags, and a similar new task, immediately and after a 2-week retention period.

Main Results:

• Results supported the variability-of-practice hypothesis, demonstrating enhanced schema formation and transfer to novel tasks within the same movement class.
• The group practicing with variable weights showed significantly less performance loss after the 2-week retention interval compared to other groups.
• Variability of practice facilitated more robust motor schema development and retention.

Conclusions:

• Variability of practice is effective for motor schema formation and promotes better learning and retention of motor skills.
• Training protocols incorporating varied practice conditions can lead to more durable skill acquisition and improved transfer.
• The findings have implications for designing effective motor skill learning programs for children.
