 An unconditioned motivating operation is a motivating operation that has not been conditioned No, that doesn't work. No God. I hate it when I do it. No, I'm kidding. It's true The word unconditioned always bothers me hasn't been conditioned. No, it's just that it's that you didn't need conditioning in order for it to work Really, right? What is that supposed to mean? Well, think about it for a second If I withhold water from you for like, I don't know 14 15 16 days I mean ours. It might be that you will engage in behaviors to seek out said water, right? So there is a motivating operation present one could say thirsty But that is so not behavioral to do that. It's not observable. So we just say since it's been 14 hours since your last drink of water We assume this person is engaged is going to engage in water-seeking behavior Right, you get what I'm doing. I'm being highly technical with my description But the unconditioned motivating operation part is that you didn't have to learn anything special about that, right? It's just a it's a reflexive sort of thing I mean if I withhold oxygen from you for a while, I'm sure you'll desire oxygen and it'll create a motivating scenario That's the point. It prompts you to engage in it sets up a condition where engaging in certain behaviors will produce reinforcers but it's without learning history because you didn't it's keeping alive and sex and food and water and air and It's all the unconditioned stuff
