I feel like I've recognized a sprinkling of terms and concepts on the MCAT, AAMC official guide, and AAMC sample test from all the sociology and psychology classes I've taken (did not major, just took 4 total classes I was interested in). I didn't take intro sociology and I only did AP Psychology like 7 years ago. However, in undergrad, I took one mid-level sociology class, two mid-level psych classes, and one high-level psych class. They were not majority MCAT-terminology-oriented, but just seeing ideas that could show up on the MCAT in a class before doing MCAT prep will not hurt you once you start your prep.
My point based on my experience: any sociology/psychology class will teach you at least a few terms that are on the MCAT. I don't know which specific classes are more high-yield for the MCAT, but like allantois said, you can learn it all through content review. And honestly, based on my and several others' perspectives on here and Reddit, no matter what amount of content review you do for these subjects, you will likely still see some terms or -ologist that you've never seen. I also agree that a bio-oriented psych course will help; I took a neuro-behavior psych class 3 years ago. I don't remember much specifics from the class, but I know it aided my recognition with several terms!
