 I'm going to do my best to make Rascola and Wagner proud because if you understand Rascola Wagner, you understand unpairing. Unpairing is really easy, folks. We're getting deeper into it just so you can make it more cool and give us more time on the video because really, all we have to do is worry about this. Remember that when you're talking about classical conditioning, which is the best way to deal with this example, mind you, a CS must predict a US. In the way to make that work, and if you go back to the original article, it talks about varying the probability of the US occurring in the presence of the CS. So if you want to establish conditioning, that's the way you do it. US happens in the presence of the CS, so eventually the CS comes to predict the US. Let's break that prediction, unpair. Present the CS over and over. That's one way to do it. Or you could present the CS without the US. Actually, you could still present the CS, but just make sure it's not contingent that there's no same time or predictability. Actually, you don't want the same time that's simultaneous conditioning. It doesn't work as well. So trace conditioning. So anyway, you get the idea, folks, you're going to unpair something by breaking the predictability between the two stimuli of a CS and a US. Generalize that over into reinforcers and condition reinforcers, and you understand what we're getting at.
