How does Soar currently stand as a psychology theory?
Sadly, there is not a cut and dried answer to this question. Answering this fully will require you to figure out what you expect from a psychology theory and then evaluate Soar on those criteria. If you expect a theory to predict that humans are intelligent, and that they have been and can be shown to learn in several domains, it is nearly the only game in town. If you require limited short term memory directly in the architecture, that’s not in Soar yet (try ACT-R). With this in mind, there are numerous resources for finding out more. The first port of call should be Newell’s 1990 book, Unified Theories Cognition. This may satisfy you. This makes the most coherent case for Soar, although it is slowly becoming out of date with respect to the implementation. There are also two big books, The Soar papers (Vol. 1 and 2), that provide numerous examples of Soar’s use. The examples tend to be more biased towards AI, but there are numerous psychology applications in them. If you go to the ISI
