On privacy, causes, and contingencies

Radical behaviorism may be distinguished from other varieties of behaviorism, notably methodological behaviorism, by the way it accommodates private events in causal explanations of behavior. That is, in an operational sense, radical behaviorism accommodates private phenomena in the context of the three term contingency of reinforcement with regard to their discriminative function, their nature as responses, or their reinforcing function. In any case, any contribution of a private phenomenon is presumably linked at some point to a prior public event that has endowed the private phenomenon with its functional significance.
