 Well, all right. So an unconditioned negative reinforcer folks, I don't know why isn't it except what it's going to keep it for now. So anyway, so an unconditioned negative reinforcers when you escape something, since it's negative, right, negative reinforcer you escape, your behavior is going to increase, you're going to increase the probability of this because it's a reinforcer. So negative reinforcer uncondition, the thing you are escaping is something that you did not have to learn about. In other words, you know, like loud noises. That was supposed to be a storm. But anyway, so loud noise is extremely hot things like inside of a volcano. You know, you escape that, it's going to be better for you. So basically anything that the two species finds punishing without any learning history. When you escape those things, loud noises, hot sounds, hot sounds, loud noises, hot sounds, you get the idea. Basically when you when you escape any of that sort of stuff, an unconditioned Punisher, that is an unconditioned negative really, negatively reinforcing situation. Also when you avoid those things, but that gets a little trickier to think about logically. So we'll just focus on the escape side of things. Unconditioned negative reinforcement.
