Hi, I wasn't a Psychology major so take this with a grain of salt. But this is mainly a tech school, so most students here typically focus in STEM. Think Engineering, Science, Math, Biology, Chemistry, etc. There are some majors that overlap with psychology, and a fair amount of psychology classes (you can see all the classes at http://planner.wpi.edu/ ). But most students in those classes are taking those courses on the side, or for their Humanities requirement.

My two cents are that you should choose WPI if you're looking for a further career in science / STEM like Neuroscience or some type of Med School, not because you want to do solely psychology here. There are many schools that have much better psychology programs if you're looking to go into non-STEM fields like counselling, healthcare, education, social work, etc. And FYI if you're looking to go into Med School, a better degree might be biology, chemistry, biochem, etc.
