Directional aiming bias in golf putting

Area of Science:

• Sports Science
• Perception and Action
• Motor Skill Acquisition

Background:

• A visuospatial illusion can make accurate golf putting difficult, causing a directional bias.
• Previous research suggests this illusion impacts the perception of the putting line.
• The two-visual-pathway hypothesis offers a framework for understanding these perceptual-motor effects.

Purpose of the Study:

• To investigate if a known perceptual aiming bias affects golf putting performance.
• To compare expert and novice golfers' responses to this visuospatial illusion.
• To examine the relationship between perceptual aiming and action (putting) biases.

Main Methods:

• Participants: 24 expert and 24 novice golfers.
• Tasks: A perception task (aligning a line to the hole) and an action task (putting to a hole at 1m and 4m).
• Analysis: Measured perceptual aiming bias and action aiming bias in putting.

Main Results:

• Novice players exhibited a significant perceptual aiming bias and a smaller putting bias.
• Expert players demonstrated no significant bias in either the perception or putting tasks.
• Results align with previous findings and support the two-visual-pathway hypothesis.

Conclusions:

• Expertise in golf appears to mitigate the effects of visuospatial illusions on putting accuracy.
• Skill differences in golf putting may reflect refined calibration between visual perception and action.
• The study provides further evidence for the two-visual-pathway hypothesis in skilled motor performance.
