 I think we'll start this out with a demo of the Hilbert chain, as you're going to have eight pads. One, two, five, I'm in the house! You grabbed by the pumpkin full of iron. We might be wrong. We're buddy, but not always a gentleman. You know. Looks like I'm taking a wee, if you're coming from the other side. Ladies and gentlemen, there's, as usual, here at Psychor, there's always more to the story. So, well, let me find my way out of this mess here. Alright, there we go. Hi. So, that was really weird. I echo a lot in there. Anyway, that's really about bothersome. Anyway, a couple of things we need to know about some schedules of reinforcement. They just kind of want to add that we haven't really included in some of the other videos. The first thing is I want you to be aware of a limited hold. Way cool technique, alright? Everybody's familiar with the limited hold, but it can sometimes be difficult to use, but I think that's a really important procedure to be aware of. And to use, as you see fit, maybe often, hinted wink, wink, nod, nod. So, that particular procedure, limited hold, is where you make the completion of a schedule, right? So, you've got one of your basic schedules. It could be complex, but anyway. So, you get a schedule, right? Let's say an FR, fixed ratio, seven, whatever that means, right? So, we have an FR seven, and the completion of that should deliver a reinforcer, right? However, you could put it on a limited hold, where it's only going to be available for a certain amount of time. So, meaning you have to complete your FR seven within a given timeframe. If you miss it, if you miss the end of that timeframe, no reinforcer for you. It's like, no soup for you, right? So, for an old, that's a really old Seinfeld reference. Like, none of you guys watching this are going to get it. But if you do, great. Congratulations. And you get reinforcers for referencing an old TV show. So, limited hold, again, reinforcement is only available for a specific period of time. So, you still have to complete the schedule, but it has to be done within a timeframe. So, let's see what other stuff do we need. Ratio strains, alright? Since we were talking about a fixed ratio, I briefly mentioned ratio strain in another, and probably two or three videos. But it's important because when you're really pushing on somebody, when you're really working hard, you're getting that ratio up there, and you're thinning out the schedule. And that's another thing we're going to talk about here in a sec. So, you're thinning out the schedule, you're reducing the amount of reinforcer that you're delivering for the behavior. You've got more and more behavior being held by the schedule that you're on. You're thinning it out, you're thinning it out, and all of the person says, I'm done. I am not going to work for you anymore. I've had it. I've had enough. I'm done. I quit. I'm out. Ratio strain, right? Thinking back to the Penny Packers-Pedens video, and I'm kind of giggling, so go look that one up about ratio strain. You'll understand why I'm giggling. So ratio strain, that one. So again, that means you just pushed them a little too far. Not enough reinforcement available for that particular behavior to maintain. So you might have to rich it up that schedule a little bit or thicken up that schedule a little bit. So the last thing is thinning the schedule, right? Which I should have done before the ratio is strained. But anyway, so you start out quite rich, right? So you've seen the other videos. You understand that reinforcement should be done initially very frequently. So maybe a continuous reinforcement schedule, and then you start to thin that out, right? So as you thin that out, you're going to get effects each time you start to thin that out. So be wary of the fact that if you take too big of a jump, you're going to lose the behavior. You're going to put the personal ratio strain or whatever the case may be. And they're just going to essentially stop working. There's going to be all sorts of other things that happen, because functionally speaking, as you thin that schedule, you're really kind of in an odd way putting people on an extinction procedure. So not directly, but you get what I mean. If you were on a continuous reinforcement schedule, so for every behavior that you're engaging in, you've got a reinforcer for it. Then we start to thin that out. Now you're going three, four, five, six behaviors before you're in a reinforcer. Three, four, five, and six are all, or five are all extinction. Because you're not in a reinforcer for those. So that can be challenging to deal with. You do want a program for this. It's really important in order to make sure that you are switching from contrived scenarios to natural scenarios. That's kind of the idea with thinning the schedule is you're delivering your contrived reinforcers early on in the program. You want to fade those out and get rid of those to where the natural reinforcers take their place. You do that by thinning the schedule. So I think that's a pretty good little vignette on some of the things you need to worry about with schedules reinforcement. And I'm sure there's plenty more to talk about. So I'm going to go back over here because it's really cool.
