 I think we'll start this out with the demo. We got a hell of a change as you're going to have eight hands. I'm going to drive a bit loud! You're going to have to buy the function full of her. We might be wrong. We're funny, but it's not always a joke. I promise you have to clap for me first. If I was able to clap without moving my hands, would you laugh? That was a case of imitation. New response I learned. You're recording right now. Sure, of course. Alright, here we go. I honestly have no idea why I'm sitting in this position. Probably because I'm as confused as you are, because this is not the first time we've recorded this video, which I've given this lecture, I don't know, maybe 150 times, 200 times. I've never screwed it up until I put myself behind a camera, and then I completely buggered it and buggered it more than once. So we're here to tell you that it's not going to get buggered this time. And I know that. I'm going to beat this into you because I brought a hammer. I often don't leave the house without a hammer. This is an interesting hammer. Sorry, I really am proud to say, made in the US, I'm proud to say that I didn't leave the house without a hammer. I don't know. Folks, I'm showing you the hammer for a particular reason, because I'm talking about stimulus equivalence. And so this would be a hammer. So if I showed you this, we were trying to demonstrate reflexivity. So that's the most simple form of stimulus equivalence training. So we got a hammer, and I show a series of pictures on the wall over there. So I don't know, pick the one that's a hammer. And if you correctly pick it without me training you, so I just show you this, and you pick the hammer out of that list of images, then congratulations, you have reflexivity. A equals A, hammer, hammer. You picked the hammer, congratulations, well done. So that's really simple, let's go for symmetry. This time I'm going to try to set this up over here. Gravity works better on you. This is not a physics class, I apologize. So now we have a hammer, but we're going to make A equal B. So if I'm demonstrating symmetry, then when I show you a hammer, and I show you a list of written words, so when I show you that list of written words, you will choose the word hammer out of the list. Now, that's kind of the initial part to test whether or not you've actually developed it. You flip everything around, you hang this up here, and I show you the word over here. So I show you the word hammer, and hopefully you'll choose the hammer from the list. So that would be symmetry. So the last one of stimulus equivalents has to do with, well not has to do with, it is transitivity. This is A equals B and B equals C, therefore A equals C. Isn't that the way it's always taught in class? Just you write A equals B, B equals C, A equals C, and you didn't test it, and A, life's good, you have transitivity. Well, we're going to do a little bit better of an example here. So hammer, okay, that's our stimulus. So we're going to focus on stimulus. I'm going to connect this with the written word hammer. And when I connect this with the written word hammer, then I'm going to take this away, and I'm going to put the written word hammer here. And then I'm going to have, actually now, yeah, that'll work, whatever, doesn't matter. So the written word hammer is here. Now I'm going to have three audio files, say, I don't know, whatever they are. One of those audio files will say the word hammer, okay? So now you can connect the written word to the spoken word. Now the question is, if I show you this, and then you have the list of spoken words up here, well, do you actually choose the one that says hammer? Because I never connected this physical object with the spoken word hammer when you're trying to train someone. I did the written word and so on and so forth. So we can play with this around a little bit. But the idea then would be flip it back around and go present the audio and see if you can eventually choose the hammer out of the list of words. So, transitivity. So that would be your basics on what you call it. What is this? This is why I always forget what stimulus equivalents. So, made it. Without a cut. All right, so stimulus equivalents, we can talk about match to sample procedures and develop the training around all this stuff, but really we're just talking about different types of discriminations and generalizations. We're really talking specifically about special cases of stimulus control. So, I don't know what else we need to go over here. Is that it?
