Reinforcement: The metaphorical, symbolic, or actual point where behavior is strengthened, altered, or otherwise changed. A reinforcer can be many things. It can be an object as large as a house, or objectified in a subtle change of feeling. It can be displayed as a change in observable behavior, or a change in the likelihood of behavior yet to come. It can be an event that 'pulls' behavior from us, like a Pavlovian reflex; it can be an event that 'pushs' and is glued to behavior like a Skinnerian positive reinforcer; or it can be a mere wisp of a thought evidenced in a simple change of mind. In short, like the cheshire cat, it is here, but never here, a tease perhaps that's needed to get us about in Neverland. It is something everyone knows and no one knows. Indeed, if this author knew for sure, he would write it here, and find the revelation no doubt very reinforcing indeed.
