 Watch out, folks. He has an abundance of hair. I think that's a hint. Bonus response cost, which is the entire idea that if you're going to implement a negative punishment procedure, see, negative punishment, you will have something to take away. And that means that if a kid continues to exhibit a behavior that causes him to lose a reinforcer, he doesn't lose all of his reinforcers for doing the correct things. So my favorite example is every time Timmy yells in class, he loses five minutes of recess. When he's reinforced for the correct thing, he can earn ten minutes of recess. The idea behind a bonus response cost is so that the kid doesn't end up owning you six weeks of recess for something he did four months ago. I still owe that bitch. Dead collectors. Perfect example of why we need bonus response costs. Ooh, I like it. Cheerio.
