 So different there, this is helping you. You're going to like this. Alright, we're here with a full session, DRL, differential reinforcement of low rates. The idea being say, throughout a class time or a whole day, we're going to decrease cussing, right? So over the course of the week, you're going to allow 10 cusses on Monday. If it's at 10 or under 10, you're going to be reinforced. But on Tuesday, you're only going to allow someone to cuss eight times on Tuesday. If it's at or under, you're going to reinforce and so on and so forth, going down throughout the week. So on Friday, no one is allowed to, or they can only cuss through four times. Differential reinforcement of low rates, full session.
