 discriminated operant. It's an operant that occurs more frequently in one condition than in others, or in one environmental setting than others. So you might ask, what's an operant? It's a fancy way of saying behavior. It's a little more than that, but that's good enough for now. So a behavior that happens more frequently, or even arguably less frequently. Anyway, so the frequency of a behavior changes in one context versus another. I'm hilarious on camera, but my wife thinks I'm boring as hell. Brad back there does back hand springs if you give him in the right to environmental conditions. So he'll do them all day long and I'm not going to tell you why or how because it's a secret. Anyway, the point being that you learn to discriminate when a particular behavior is going to get reinforced and the end result, the effect, is a discriminated operant that you engage in a behavior more frequently or less frequently in certain contexts. That's it.
