When you mimic or imitate certain motions that a character is making in an effort to "boost" that action. For example: pulling up the controller when you're reeling in a fish in a game, or turning the controller when making a sudden turn in a racing game - even if the game doesn't read your movements. Or hissing out in pain when your character gets shot/punched. And so on. I know it's part of being "immersed" and without thinking it we like to hone that sense of immersion, but is there a psychological term for it?
