 a fixed momentary DR0. DR0. DR0. DR0. DR0. I'll let you decide whether it's an issue. I'll let you think about it. I think there might even be a rant on our channel somewhere about that. I don't really remember where it is, but I remember ranting about it. But I've ranted about it a lot, so I really don't know. So what we could be thinking about here is, you know, maybe you're the one doing the, what is it called? What was it called? A fixed momentary DR0 is like, you're going to look up after a given fixed amount of time. And at that moment, if anything other than the problem behavior is occurring, you're going to deliver reinforcers. Okay? All right? So a fixed moment in time, you're going to deliver a reinforcer if the problem behavior is not occurring. And I know that sounds weird because it's a DR0 and a DR0, and they're really just differential reinforcement of other behavior or zero rates of the problem behavior. But an organism can't not respond unless they're dead. So they're doing something, right? So you're going to reinforce other behavior at that particular moment. Maybe it's every five minutes, whatever it is. So fixed momentary, and you're going to just take a peek. Is that behavior occurring? Reinforce if it's not, and just reinforce whatever behavior is occurring. That's it.
