Psychology vs Psychology & Social Behavior?

Hi! I am an incoming freshman at UCI. I got accepted as a psych major (cognitive science).

During orientation I plan to request a change of major to Psychology & Social Behavior as I’m more interested in that field of psychology. However, one of my original plans with a psych major was to become a neuropsychologist… which means I should stick with my Cognitive science/psych major, right?

Long story short, I don’t know if I should stick with Cog Sci or switch to PSB. What are the main differences?
Sorry if this is confusing but any help would be appreciated.

Stick to cog sci
