IRS -- Individual Reward Systems
Here's a thought. What if, instead of having a set of consequences for negative behaviors, I had a set of rewards for positive behaviors? Deposits for being good instead of demerits for being bad. Food? Money? Entertainment? That kind of external reward system doesn't nurture the development of internal motivation, but for some kids it might be novel enough to be effective. Maybe, eventually, "being good" will become rewarding in its own right and they can be weened off of the life-support of external controls.
