I posted this thread on r9k but perhaps this board is more appropriate for it.

>think about wanting do to a certain action
>don't do it

I wonder what are the mechanisms behind this.
For example, when you think about punching in the throat someone you're talking to but you don't do it. Or when you think about going to the gym but you don't do it. Instead, if you think about picking up a pencil, you do it. What is the filter between our thoughts and our actions? Can it be manipulated to make previously "blocked" actions available to do? And also, can it be altered to make previously "allowed" actions blocked?
