Abstract

That every response is also a stimulus has important implications for how we characterize the private experiences of both people and non-human animals. Acting as stimuli, responses, whether covert or overt, change the probability of subsequent responses. Hence, all behavior, covert and overt, is necessarily associative in some sense, and thinking may be characterized as “covert autochaining.” According to this view, animals capable of responding to temporally remote stimuli and to characteristics of their own bodies necessarily engage in some form of associative thinking. This characterization of thinking necessarily presumes that private behavioral events adhere to at least some processes that occur in — and have been extensively studied in — overt behavior. To assume otherwise, as do Daniel Dennett, Robert Nozick, and others, is to be unnecessarily pessimistic both about the robustness of evolutionary processes and about our ability to explain complex human phenomena in rigorous empirical terms.
