 All right, I hope you're ready. We're back for escape and avoidance. All right, escape and avoidance, here we are in negative reinforcement, all right. That's what we're really talking about with regard to escape and avoidance is that, again, we're gonna strengthen a behavior, but we're gonna do so by contingently removing or avoiding a stimulus. And so the definition that we're gonna function with here or work with in terms of this course is gonna be the increasing of a behavior by the contingent removal of a stimulus. So again, the contingent is the part that it's a rule, so you have to do the behavior first. The behavior causes the removal of a stimulus. And there's two different ways to think about that removal of a stimulus, but we'll get into that in a second. Of course, that's the title, you can escape it or you can avoid it, all right. So from a different perspective or from a more cloak wheel perspective here, the loss of a stimulus following a behavior can increase the frequency or occurrence of that behavior. And that is negative reinforcement. So again, negative does not mean bad. You gotta get, you don't wanna think of that. You don't wanna think negative is bad and positive is good. Negative is just the loss of something. So take a aspirin is the behavior, the loss, what do I lose as a result of my headache? Flip the light switch, right? What do I lose? I lose the light, right? So if I'm turning it off, okay, so I've got light in the room and I'm leaving for the day and I flip the switch and there you go, the light goes off. That negatively reinforces me flipping the light switch. If I want the lights off, pretty straightforward. Again, here's the contingent part. The stimulus must be present. Oh, I'm sorry, it's not the contingent part, I was misreading my slide. In order to deal with escape, right, the stimulus must be present. That's, you have to have that first. So in other words, think of the car, you know, the, you know, the beep, beep, beep, you know, that sort of thing when you haven't put on your seatbelt, right? So you get in a car, you start driving on a road and it's beeping and that stimulus is now present. So when you then connect your seatbelt, it is negatively reinforced by escaping that stimulus. So with regard to escape, you must already be experiencing that aversive stimulus. Another thing that I've thought of here or that I've experienced here with regard to escape has to do with, let me say, like if you're out in the cold or something like that, you've got your gloves on, you got all that stuff on and you're still a little bit chilly. So what do you do? You take and open one of those little hand warmer things and sure there's this positive thing added that heat is actually added, but you're also escaping the cold. So you're escaping that cold feeling on your hands or in your feet or wherever you're putting those little hand warmers or tow warmers, whatever they are, right? So you're escaping that and that's gonna negatively reinforce you using those particular pads in the future. But again, you have to be experiencing something in order to escape it. It's a little different for the other side of negative reinforcement for the avoidance examples.
