 All right, welcome back to Cycler's YouTube channel. We have ourselves the DRI. And I'll let you know what that means. It means there are certain behaviors. I don't know when I'm going Irish now. Anyway, certain behaviors that are incompatible, differential reinforcement of incompatible behaviors. For instance, I've had Kettos where they have a stimulatory response or some type of tantrum, if you will, where they're doing something like this and they can't do anything else and they can't get stuck or they get stuck in this pattern and they have TAs that prompt them to go and it's completely incompatible. Now they have to keep their hands closed and you're going to reinforce them for keeping their hands closed because they're no longer doing this and making a big scene in the mall. DRI.
