 acquisition. This is the period of which you're acquiring the skill. Basically this is the learning stage that it would be a learning curve, so you're acquiring it. It could be acquiring a response of any kind. It could be when you're going through classical conditioning or you're acquiring that conditioning status, whatever you want to call that. That's kind of a weird way to think of it. But anyway, so the acquisition phase might be another way that you could do it, or describe it, but acquiring. You're getting something. You're gaining something. You're learning something. You're suddenly able to perform a behavior. However, you need to be really cautious about what it is you are acquiring. You are acquiring skills. You're not acquiring knowledge, okay? Because knowledge is something inside your head, but you cannot measure. And we'll talk about that later with private events. Thank you very much. Talk to you later. Bye.
