HOW DO WE LEARN ??

[straightline]

Something I should mention because it can be important in pool but is not covered in the material I linked to: While an internal focus generally negatively impacts performance and learning, this only applies when the focus is on what you are trying to do - on the stroke. For various reasons I won't go into, there is no problem in retaining some focus internally on something that is not, or should not be, involved in the shot.

So attention to keeping your head still when you deliver the shot is not hugely destructive, and may be helpful to someone who has a habit of moving on the shot (although an external focus, staying down to watch the cb bounce off the ob is probably to be preferred if it works for the individual).

Similarly paying some attention to keeping unwanted movement out of the wrist and shoulder can be useful.

Pool is relatively simple as far as technique goes. I think humans can deal with slightly more complexity than shooting a shot - without affecting the shot. I also think pedantics should be left in the PSR and probably only in the rehearsal PSR.
At <shoot time>, the tip of the stick is where the focus should uh, focus. Watch the Judd Trump clip Greg Cantrall posted. Lots of stroke related motion seriously - head, torso, legs; not Iron Willie by any means. The balls on the other hand show no such instability.

I purchased a book that the Lion recommended on a podcast that deals with all this.
With Winning in Mind by Lanny Bassham great read
