 DRL, differential reinforcement of low rates of behavior. Sorry, my brain's moving too quickly. I'm trying to reinforce it as it slows down. You get the idea? Right, so we're just gonna reinforce a lower rate of responding, okay? So whenever the organism, the person, whatever's engaging in fewer behaviors per interval or per minute, per hour, whatever, maybe you're doing the whole session, whatever. So whenever they're engaging in fewer behaviors, you can drop a reinforcer on them, right? So the idea is that over time, if you drink it, if you really drop it on them, it might actually be punishing. And there's a funny thing for you. Anyway, so no, deliver a reinforcer when the behavior is occurring at a lower rate than what it was in the past. Over time, you're gonna see that this slows the behavior down. It sounds kind of odd and some people get a little confused because you're really reducing the rate of a responding using reinforcement. And reinforcement strengthens behavior. Kind of, it reinforces the current rate, right? So you have to think of behaviors a little more molar. It's not quite as molecular as what most people think of it. And as a result, you can reinforce a rate of responding. So when that rate slows down, deliver a reinforcer. Rate slows down, deliver a reinforcer. If it's happening it too fast, then you might wanna think about one of the other DRs, like maybe a diminishing rates or something like that or a duration issue that you're trying to change. So anyway, differential reinforcement of low rates of behavior.
