As many long-time LBOsters know, I'm a psychology professor (with tenure and everything!), so I feel compelled to respond to Chuck's claims above. First, psychologists have developed many "explanatory theories of mind", from Freud to cognitive psychologists like Sternberg to neurocognitive theorists. You may disagree with one or more of these approaches, but psychologists are definitely not lacking in the "theory of mind" department. Second, Sternberg is a cognitive psychologist; the cognitive perspective is fundamentally at odds with the radical behaviorist ("rat theory") perspective. Radical behaviorists like Skinner reject the notion that mental processes can explain behavior.
