Enhancing performance expectancies through visual illusions facilitates motor learning in children.

Area of Science:

• Motor learning
• Visual perception
• Developmental psychology

Background:

• The Ebbinghaus illusion, a visual illusion where a central circle's perceived size is influenced by surrounding circles, affects adult golf putting performance.
• Previous research indicated that adults learning golf putting improved more when the hole appeared larger due to the illusion.
• Children's sensitivity to visual illusions and its impact on motor learning is less understood.

Purpose of the Study:

• To investigate if the learning advantage observed in adults due to the Ebbinghaus illusion generalizes to 10-year-old children.
• To examine the effect of perceived hole size (larger vs. smaller) on children's golf putting performance and self-efficacy.
• To assess the impact of the illusion on motor learning, specifically delayed retention performance.

Main Methods:

• Two groups of 10-year-old children practiced golf putting from 2 meters.
• One group practiced with a perceived larger hole (illusion-induced), while the other practiced with a perceived smaller hole.
• Self-efficacy, practice performance accuracy, and delayed retention performance were measured.

Main Results:

• The group practicing with the perceived larger hole showed increased self-efficacy.
• This group also demonstrated superior putting accuracy during the practice phase.
• Crucially, delayed retention performance, indicating learning, was significantly enhanced in the perceived larger hole group.

Conclusions:

• The learning benefits of the Ebbinghaus illusion in golf putting extend to 10-year-old children.
• Enhanced performance expectancies, fostered by the perceived larger hole, appear to be a key mechanism for optimal motor learning.
• Findings support the generalization of visual illusion effects on motor skill acquisition across different age groups.
