Abstract

What are "private events" and what is their significance? The term is B. F. Skinner's, but the idea is much older. Before J. B. Watson challenged their methods and their metaphysics, virtually all psychologists assumed that the only way to discover a person's supposedly private states of mind was to ask her about them. Not a believer in minds, Skinner nevertheless agreed that sensations, feelings, and certain unspecified forms of "covert behavior" cannot be observed by others, because they take place inside the body underneath the skin. Then he added that these inner events are of interest only to the physiologist; the concern of the behavior analyst is how intact organisms interact with their environment, not how their inward parts interact with each other. That compromise enabled Skinner to pursue behavior analysis in disregard of neurophysiology, which there was at the time no good way to study anyhow. But Skinner's talk of ineluctably private events was ill considered and ill conceived. There is no well understood sense in which people observe their own sensations, feelings, and "covert behavior," but if these take place inside the body, as it is reasonable to believe, the physiologist can observe them given the sophisticated new machines now available. And since these events inside the body vary with circumstances and influence behavior, the psychologist cannot afford to ignore what the physiologist has to say about them. Black box psychology is out of date. Though it is opaque, the skin is not an epistemological barrier
