As far as I know it doesn't make any difference at all whether your psychology degree is a B.A. or B.S. Often a university will award only one or the other so you probably won't have a choice except by what university you choose to attend. If you want to be a clinical psychologist you will have to go to graduate school and obtain either a masters or Ph.D. Again I doubt that graduate programs will care whether you have a B.A. or B.S.
I hope this information is helpful. I wish you the best in pursuing your career goals.

I would assume that since Psychology is essentially a science that studies behavior, a BS could be better, especially if you are looking into clinical psychology. I have a Master of Arts for Human Services Counseling, but it does not allow me to work in clinical positions. Schools will only offer one or the other. I would recommend you look into the reputation of the school and whether they have an excellent program rather than the type of degree. It is also important to look at which one will give you the prerequisites for graduate school. Most careers in psychology will require a graduate degree.
