Psychological Sciences

From the neural basis of behavior in non-human animals to interpersonal interactions and relationships, the Department of Psychological Sciences trains students with an expansive understanding of psychology while also combining it with other sciences. Home to the some of the world’s leading psychology experts, the department offers abundant research and education opportunities for both undergraduate and graduate students across a wide range of psychology topics.

Undergraduate Programs

As a student in one of our two undergraduate majors, you’ll gain a broad foundation in psychology and find out what makes people tick by exploring the human brain and mind. The psychological sciences major offers maximum flexibility to tailor coursework to your interests, while the brain and behavioral sciences major emphasizes neuroscience and cognitive science. Students within both majors can earn course credit for work within faculty research labs. You may also apply to our Research-Focused Honors Program beginning in your junior year to conduct an independent research project under the close supervision of a faculty member.
