 Fixing my caterpillars as my children call them. Anyway, sorry folks, I am operating under multiple schedules of reinforcement that I've established myself. Anyway, no, it's not really that odd when you understand what a multiple schedule is. It's another compound schedule where you have two or more simple schedules of reinforcement or semi-complex ones. Whatever. I'm just talking to myself in a circle today. Two or more schedules of reinforcement operating at any given moment. The cool thing about a multiple schedule is that it's signaled. You know when you're on this one or that one because it has a discriminative stimulus associated with it. Red light, green light, red light, green light. And then you bounce between your VI-5 and your FR-7, whatever it is. So at least it's discriminated. So the organism knows what knows. At least it's signaled what schedule of reinforcement you're operating under. Reinforcers are delivered for the completion of any element along the way at any given time that you choose.
