How do you address compulsive behaviors in the classroom?

Rob, what are some ways to address some very serious compulsive behaviors or rigidity in the classroom? So that's a broad class of behavior. We know what are they doing compulsively when two kids playing with themself, somebody is compulsively hand in his pants? Is he compulsively putting things in his mouth? Is he always blurting out? It really depends on the individual and the type of behavior. If you're talking about behavior, behaviors that are automatically reinforced. And the behaviors that are listed often are in some cases then probably very similar strategies, I guess, at the baseline without knowing the individual, the same thing. It's like, what are some things that you can do to get them engaged in alternative behaviors that have more powerful reinforcers for them? There was a study a couple of years ago where they were looking at things like skin picking. And so they did some training of what this campaign looked like, what it not look like, some sort of simple discrimination training. And then they use what was called varro. So a differential reinforcement of other behaviors. So they sent a period of time. And the individual, the young woman, and she was reinforced for a certain period of time without new scabs on her wrist, on her fingers, that that's a nice way. Sometimes you may not be able to catch them actually doing the skin picking, but you're able to look at the redness or some sort are any sort of physical damage.
