There are unlimited terms, and no single resource will teach you every concept that you will need to know.
If you have MCAT prep books, just use your psych / soc book as a reference. Read the neuroanatomy parts and get a general idea of the CNS / PNS / ear / eyes / relevant physio.
Then go through all the KA P/S passages and study the concepts that come up as you go. For example, if you see a question asking about
reinforcement, but you don't know about it, read about that part in your psych / soc book, use google, or watch a KA video.
Use Anki or flashcards to keep track of all of these concepts and cycle through your deck after you get through all the KA passages to memorize all of your terms.
At this point you will have a core understanding of P / S concepts and you can just add to your deck as you take passages for practice, full-lengths, and AAMC material. If there is something you don't know just use keep using google, KA videos, or post on here.
At least that was my approach. I decided that I wasn't going to just read my P/S book after getting super bored within the first day and found videos to be too slow. Many others use different strategies so feel free to modify as you feel is best
I hope this helps because about a month ago I posted about studying P / S - I wasn't sure how to approach it. With a bit of studying you'll find that this section isn't as scary as the others!
If you have time you can also take an intro to psych class which covers a bulk of what you need to know.
