 I'm not going to get that, are you? Let me try again. Yeah, yeah, yeah, yeah. The definition of the word for the envelope. Prediction! Sorry. That kind of fell a little bit flat. I predicted that it would because I didn't have an envelope. Number one. No, prediction. You're wondering where the word was and why I put that shit to my head. You have to go back and watch some old Johnny Carson to understand. So anyway, prediction. It's a statement about an anticipated outcome of the result of an experiment or whatever a condition or the application of an independent variable. How about just a schedule of reinforcement? It's what you predict is going to happen. It's based on usually empirical reasoning, not just rational stuff. So you need some good evidence to make a good prediction about what you think is going to occur under certain conditions. Oftentimes we use the baseline to make a prediction about what's going to happen in the experimental phase change. I don't know what else to say other than make your own predictions about what the next video is going to be.
