 Oh, sweet, all right, so you know that I cheat now and look up definitions before I talk. That's not cheating. It's a very good way to do it. Bob-ding. Bob-ding. Yes, woo-hoo. But we do not want formal similarity, folks, otherwise it would be plagiarism. See the Jack Michael description about that, copying a text, except this wouldn't count because it's, sorry, I'm getting all my definitions confused. You probably don't care about any of that because this is about group contingencies. A group contingency is when you're just basically modifying the behavior of an entire group of people. It could be based on one person in the group. It could be based on multiple people in the group. It could be based on the entire group performing certain actions, right, so all of them. There's lots of different pieces. You're going to have to see the other videos about that, but a group contingency is where you have a contingency set up for a large group of people, but the criteria is based on, like I said, individuals, groups of individuals, or everybody in the group. I don't know why my arms are sitting like this, but I'm not cold. I just happened to sit like this for this video and didn't move. Don't ask me why.
