 Oh, space responding DRL. All right, wait, hold on. Is that the actual word? Yes, it was. Space responding DRL, differential reinforcement of low rates of behavior. For those of you that don't know what a space responding DRL is, it has to do with when you have intervals with a little, a little, a little, a little, a little. Anyway, I screwed it up. Anyway, so the point is, is that you're trying to reduce the behavior, right? Or reduce the rate of behavior, so you're gonna increase the spaces between the responding. I've been often accused of speaking very fastly, class, and my students, and then historically, have listened very well. Take those to the right. It's really crazy stuff, right? They're writing everything down. Let us say it all in class and then all of a sudden, everything that they learn in class, they start to apply. And as they start to apply what they learn in class, they ask more questions as I slow down, which means that, for me, asking questions is a reinforcer, and it reduces the frequency of me speaking quickly. So as I reduce my rate of responding and increase the IRT between my responses, I'm gonna pick it back up here a little bit because I'm running out of time. So as I increase my IRTs, all right, sorry, as I decrease my IRTs, so we're gonna increase the space between the responses, you could differentially reinforce that to lower the rate of behavior, right? So what I found in classes that I would early on would start out talking extremely fast. And then over time, I would slow down. My students would find a pace that worked for them, and they would keep me at that level by engaging me in discussion. So, spaced responding, differential reinforcement, or differential, what? Differential, no, DRL, differential, differential reinforcement of low rates. Differential reinforcement of low rates of behavior. Thank you.
