Training self-control by approaching desired objects and avoiding undesired objects with a joystick can improve self-control and develop evaluations of good vs. bad.

“So, if you see something that you're supposed to avoid, you pull the joystick back. So, you creating psychological distance from the temptation versus on the things that you're supposed to approach like the broccoli you're supposed to eat, you're supposed to move the joystick forward. And there's some research to suggest that this kind of automatic you're not actually moving but you know you're taking action that's often associated with movement that that can actually help improve people's self-control over time help develop evaluations such that okay the for dieters for example the chocolate cake is bad but the broccoli is good.”
