 chaining. Are you ready for this? No. Sit down. Get comfortable. Don't watch us and drive. God, don't watch us and drive. But please watch us. I'm not saying don't watch us. Chaining. Various procedures for teaching behavior chains. Bullshit. You know what a behavior chain is? A behavior chain is a set of behaviors, right? Let's take tying your shoes or even getting into your car. One of the two. Let's go back to shoes. Anyway, you have the shoe, so the response of the shoe, and the next step becomes the SD. The completion of that particular step is the reinforcer, but also the SD for the next step, which is then the SD and the reinforcer for the following steps. You got the shoe, you're pulling it down, you're crossing, so you got SDR. Next step loops, SDR. Makes sense? Behavior chain.
