In computer gaming circles there is a very important term known as immersion, when the human player's sense of self is transferred to the player's avatar in the game. Anyone who has become completely engrossed in a novel can relate to this experience, except that in a game, choices are made by the player so the level of immersion, or identification with, a character can be deeper.
In the best professional training programs, various simulations are used to familiarize newcomers to the job, in addition to wearing the clothes or uniforms associated with that job. In a sense newcomers are "playing" out the role they are to take on professionally, until they become what they have been imitating.

We must do all we can to teach them they also have power and choice in the world.
