 Imitation. Imitation. Imitation is. Imitation is. This is one of those words that you don't really need to define too closely, right? Because everybody knows what Imitation is, so you can imitate my response, but it's like, ah, Imitation. Ah, we come up with definitions, and now there's a few things that are important about it. Specifically, it has to be in the presence of the model, okay? So that's probably the biggest thing that people screw up when they're talking about Imitation. Ah, you're just imitating your brother. No, only if brother is present, all right? So my little one, Avery, she's kind of tiny, like three and three-quarters-ish. And then the next one up, I'd want to how old is he, sneaking up on eight here in a few weeks. Anyway, so if Avery is imitating Jacob, the only way for the Imitation to be technical Imitation is if Jake does it, then she does it immediately thereafter in the presence of Jacob with the same stimuli, so on and so forth. So if she just imitates something he says six hours later, then it's not by definition Imitation. But did you notice that I colloquially use the term? I said, she imitated him a couple of hours later? That's not actually Imitation. So again, Imitation, you know what it means, but we've got to add that constraint of doing it in the context of the model. So I think that's probably the most important pieces that I can tell you. I think. I'm not really sure. Don't imitate the way I'm ending this video. And because I have completely forgotten sorts of things over the sorts of things. All sorts of things over the year. The other piece with Imitation happens to be a new behavior, something that you haven't done in the past. Why? Because if you've done it in the past, then it's either been shaped or it's been reinforced. Now it's not an Imitation, right? So it's a new behavior. You're copying what Jacob did, or Avery's copying what Jacob did, just in the presence of him. So it's immediacy and it's a new response. Those are your keys.
