Brown University's Department of Cognitive and Psychological Sciences is dedicated to the multidisciplinary study of mind, brain, behavior and language. It offers  two Ph.D. programs: in Cognitive Science and Psychology. Ph.D. students are accepted by the department and formally choose one of the  two programs during the first year. The department does not accept students interested in obtaining terminal master's degrees.

The Cognitive Science Ph.D. program is designed to prepare students for careers as scientists and teachers who will make contributions to society in academic or applied settings. Students will gain broad competence in the scientific issues and experimental, theoretical, and/or computational methods relevant across fields of cognitive science and will develop expertise in one or more research specializations. Programs of study are highly individualized; decisions about research and coursework are made in close collaboration with a research advisor and graduate committee chosen by each student. Students may change areas, programs, and/or advisors as their interests develop. Students are also encouraged to collaborate with faculty members who are not their primary advisors.

Students accepted into the Cognitive Science Ph.D. program are guaranteed five years of financial support contingent on satisfactory progress toward the degree. In addition to the Graduate School's doctoral support, the department also typically provides a summer stipend for a fourth summer if the student continues to work on research over that period. Support normally comes in the form of teaching or research assistantships, and students are encouraged to apply for their own fellowships (e.g., NSF) before or after being admitted to the program.
