 All right, here we have recovery from punishment procedure. That's kind of a problem here. The idea with punishment is you're decreasing a behavior. Well, you better make sure that every time you punish, you should be contingent on the behavior. The issue is, with this particular thing, if you have a behavior come back and you don't punish them, it recovers. Because that contingency is no longer in place, and it just meant reinforcement. So now you have a once-punished behavior recovering from your punishment procedure. So a great example would be, I have a kiddo that pulls a sister's hair, so I punch him in the face. He stops pulling a sister's hair, and he pulls a sister's hair, and I punch him in the face, and he's done. He didn't do it for a long time, but let's say it's been a while, and I wasn't home, and he pulls a sister's hair, and, well, there was no punishment contingency in place, so all of a sudden he's recovered, and he's back into pulling a sister's hair. That's why we go with alternatives in using reinforcement, folks.
