Look up yips in Wikipedia, where there are several links. Even at club level, I have come across quite a few senior players who have the yips. One of my close friends has them to the extent that if he is playing for money, his opponent(s) won't concede even one foot putts because it is known that he is quite likely to miss them!The
I've never heard of the Mayo clinic but - and call me cynical - do they offer treatment for the yips in return for money?
Can you link to a scientific report about the yips by anyone who doesn't profit from people believing in them?
