 differential reinforcement of other behaviors with an fixed interval. Does it need any more explanation? I mean just go to the other video on DRO, DR0, DR0, DR0, differential reinforcement of other behavior. Go watch that video and then come back here and oh sorry don't come back here yet. Go watch the other video on fixed intervals which is about the first response that's going to be reinforced after a given amount of time has occurred, right, or past, right? So we're gonna put a fixed interval, we're gonna put an fi in combination with a DRO schedule. So when you're doing other things, something other than the problem behavior, we're going to reinforce that only after one response after a given amount of time has occurred. So if I'm in the classroom I might reinforce a little Billy for doing something other than being disruptive every four minutes. So that would be a fixed interval 4, right? So in fi 4 and I would likely reinforce that little dude if he's doing something other than being disruptive to the classroom, Mr. Cameraman being disruptive to the set. So every four minutes you could deliver a reinforcer for engaging in a behavior other than the problem of the target behavior. So that's really all it is, it's just mixing these things together which is what behavior analysis is all about. Take these small components and mix them together to make something complex.
