Great book minus some flaws like casually reinforcing the myth that Columbus was a rebel who thought the world was round (not a central issue obviously) and not mentioning practical as opposed to merely statistical significance. No mention of hyperbolic or other time-inconsistent approaches to discounting made. Nice explanation of the Rescorla-Wagner model. Makes useful incursions into the philosophy of science at points. All told, more textbooks should be like this. Caveat: I didn't read the part of the book on memory because not interested and skimmed the chapter on connectionism because already far too familiar.
