Mike,
I'm very happy to have provided you a window into a clearer mental game world. Thank you for providing a window in what you were thinking watching the video – very helpful feedback.
To answer your questions: I have a BA in business and psychology from Skidmore College (upstate NY), a Master's in counseling psychology from Northeastern University, and I'm licensed by the state of massachusetts as a professional counselor (test + 3200hrs of supervised practice to attain).
There wasn't one classes or classes that shaped my opinion that went into TMGP. It's a combination of my experience as an aspiring professional golfer with a problem choking under major pressure. My inability to find solutions from the sport psychology material available in the late 90's, and a belief that answers had to be out there. Certaintly, the classes I took at undergrade: cognitive, abnormal, neuropsych, behavior, personality, psych research, plus the two years I spent learning advanced assessment, and treatement in traditional psychology, all contributed. I can't say that there was one class that stood out the most. I did seek to blend what I thought were the best of many divisions of psychology, and my performance experience, to create my own style. That's ultimately what's reflected in the book. In psychology, and performance psychology, there seems to be two distict categories: Cog/Behavior approach and a Freudian/unconscious/personal issues approach. I didn't set out do to this, but what I've accomplished is a hybrid between them that gets deeper into the root causes of performance errors, without getting into personal issues.
Classes are hard to recommend, but as far as books go, I've really enjoyed:
Art of Learning
Blink/Outliers
Talent Code
But, I think the key thing that's lead me to form my opinions is constantly asking the question, Why, to things. I just couldn't accept what was being presented to me as fact until there was some theory that made logical sense to me.
I know I didn't give you as much as you may have wanted, but I hope I did give you some direction.
Best,
Jared
