Are there any non-pseudoscientific psychology theories? That's a good question. Here's an off-the-top-of-my-head list: Rescorla-Wagner, Pavlovian learning, Habituation, failure to thrive, opponent processes, dominance hierarchies, learned helplessness, one-trial learning of disgust, avoidance theory of phobia, short-term vs. long-term memory, chunking, the hypergeometric forgetting curve, public inhibition of non-dominant behaviors.

A challenge for Psychology in the U.S. is that Statistics is usually included in the curriculum in Spring of Senior year -- an after-thought. I've been off-and-on poking at creating a course that would put statistics immediately after Intro Psych.
