Ebbinghaus visual illusion: no robust influence on novice golf-putting performance

Area of Science:

• Cognitive Psychology
• Sports Science
• Perception

Background:

• The Ebbinghaus visual illusion can alter perceived object size.
• Previous research suggested visual illusions might improve sports performance, specifically in golf putting.

Purpose of the Study:

• To investigate if the Ebbinghaus visual illusion reliably improves novice sports performance.
• To replicate and extend findings on the influence of visual illusions on motor tasks.

Main Methods:

• Experiments adapted procedures from Witt et al. (2012), using the Ebbinghaus illusion with a golf putting task.
• Adjustments included varying putting distances (3.5m, 2m, 1m) and illusion presentation methods.
• Hole perception and putting accuracy were measured.

Main Results:

• Replication attempts failed to show the Ebbinghaus illusion influencing hole perception or putting performance.
• Modifying illusion presentation improved perceived hole size but did not impact putting accuracy.
• Performance remained unaffected even with a shortened 1m putting distance.

Conclusions:

• The Ebbinghaus illusion does not reliably enhance novice golf putting performance.
• The purported benefits of visual illusions on sports skills may not be a robust phenomenon.
• Further research is needed to understand the complex relationship between visual perception and motor skills.
