This EMDR or Bilateral Stimulation just sounds like a form of hypnosis, but by using some techie devices to help put the person into a suggestive mindset.
Once under, the player is told to forget their fears, now they are cured.
A kind of placebo....but heck, placebos work, especially in games where confidence is key to performance.
Still, the long term results of such a strategy are probably not so great. As once failure occurs, doubts as to the method's effectiveness will creep into the player's mind.
I find the description that this method 'releases past trauma' to be specious. I think it releases current fears to a degree, and puts one in a state of confidence.
Confidence is the key to pool. I think it's the main thing that seperates the cream from the crop. A lot of hard work helps. Especially if that hard work is done with a mental attitude of confidence.
