If you visualize the hole bigger, you will sink more putts? A study published by Purdue University in 2012 thinks so. "People in our study made more successful putts in a smaller hole when a visual illusion helped them perceive it as larger," said Jessica K. Witt, a Purdue assistant professor of psychological science.
"More work is needed to better understand this effect, but we think the perceived increase in target size will boost confidence in one's abilities." Her findings are in the April 2012 issue of Psychological Science.
