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.
the learning part of the book is very clear and enjoyable.I cannot say the same about the memory part, the various models and the theory behind them gets quite confusing for the undergrad student.
