Document Summary
Cognition and the mind are studied from complementary perspectives in many academic disciplines: using divergent levels of explanation and methodologies, cognitive scientists usually have specialized training in a particular discipline. The challenge of explaining how unity is going to arise: the challenge of providing a framework that makes explicit information the common ground between all. Local integration: when problems in one region of cognitive science have been tackled using tool and techniques from another region. Global integration: general models that achieve unity across the discipline. Is human reasoning based on logic and probability theory: apply probabilistic reasoning all the time. How accurate: logic and probability are branched of mathematics. Modus ponens and modus tollens: modus ponens: if a is true, then b is true. B is true, thus a is true: modus tollens: if a is true, then b is true. B is not true, thus a is not true. If a is true, then b is true.
