B.S. Cognitive Science

Major Code: CG25

The department offers both a B.A. and a B.S. degree. The B.S. requires completion of a slightly more rigorous course work. The B.S. degree may be taken optionally with a specified area of specialization. There is also an honors program for exceptional students in both degree programs.

So What's the Difference?

Getting a B.S., rather than a B.A., requires that you take more lower division classes and more specific major approved upper division classes. If you choose the B.S., you have the option of specializing in one of five areas: Clinical Aspects of Cognition, Design and Interaction, Language and Culture, Machine Learning and Neural Computation, and Neuroscience. If you choose to specialize, four of your six electives must be on the list of approved courses for that specialization. If you are particularly interested in one area of cognitive science, we strongly recommend that you specialize in that area since it is likely that the only difference in course work between a B.A. and a B.S. with a specialization is one or two more lower division classes.
