Interdisciplinary Ph.D. Program in Cognitive Science 

Note: The Interdisciplinary Ph.D. Program in Cognitive Science is no longer enrolling new students as of 2023-2024. The program is being redesigned as a Degree Specialization (Graduate Specialization in Cognitive Science), and, pending Graduate Council review, plans to begin enrolling new students in 2025. For questions regarding the new specialization, please contact the incoming co-directors Matthew Fulkerson (mfulkerson@ucsd.edu) and Caren Walker (cmwalker@ucsd.edu).  What follows is information for existing students in the Interdisciplinary Ph.D. Program.

The Interdisciplinary Program in Cognitive Science has eight participating departments: Anthropology, Communication, Computer Science and Engineering, Linguistics, Neurosciences, Philosophy, Psychology, and Sociology. Students enroll in one of these departments as their "home department" and after initial admission to their home department enroll in the Interdisciplinary Program. The degree lists both the home department and Cognitive Science; for example, if the home department is Anthropology, the degree title is "Ph.D. in Anthropology and Cognitive Science."

Program Requirements

The Interdisciplinary Ph.D. program is distinct from the Cognitive Science Ph.D. program, both in admissions and graduation requirements. The Interdisciplinary program consists of:

  1. A primary specialization in one of the established disciplines of cognitive science, accomplished through the home department (maintain good standing, qualify for candidacy in home department including any adjusted requirements for IDP students the home department has established).
  2. A secondary specialization in a second field of study – providing tools of inquiry in an additional discipline outside of the home department. More on this below.
  3. Breadth requirement – five total classes to provide familiarity with general issues in the field and the various approaches taken to these issues by scholars in different disciplines.  Composed of COGS 200 Cognitive Science Seminar (3 quarters) plus two of: COGS 201 Neural Dynamics of Cognition, COGS 202 Cognitive Science Foundations: Computational Modeling of Cognition or COGS 203 Theories and Methods in the Study of Cognitive Phenomena.  Students may substitue a quarter of COGS 260 for one quarter of COGS 200.
  4. Qualifying Examinations as specified by the home department; the student must demonstrate familiarity with the approaches and findings from several disciplines relevant to the proposed dissertation research and must satisfy the committee of the quality, soundness, originality and interdisciplinary character of the proposed research.
  5. A dissertation possessing an interdisciplinary character, drawing on the primary and secondary specializations as verified. The thesis committee must include at least three members from the student's home department, including the student's adviser and at least three members of the Interdisciplinary Cognitive Science Program, at least two of whom are outside the student's home department, and otherwise follows typical appointment procedures. 

Secondary Specialization

Expertise beyond home department disciplines can be defined in several ways, within or across participating departments. All existing IDP students should have an individual study plan determining how they will meet their secondary specialization which takes the equivalent of a full year of study, optionally spread over several years.  Ideally, students who elect to do research in their areas of secondary interest will be able to accomplish a substantive piece of work, either of publishable quality or that will be of significant assistance in their dissertation projects.  If a secondary area consists entirely of courses, it will typically consists of 6 or more graduate courses, taken for a grade unless the plan justifies taking the course S/U.

Two, of essentially unlimited, possibilities for secondary specialization are below:

Cognitive Psychology: Get a basic introduction to cognitive psychology through the Proseminar in Cognitive Psychology (PSYC  218) and acquire or demonstrate knowledge of statistical tools and experimental design through the statistics sequence PSYC 201AB.  Finally, and, perhaps of most importance, the student should do a year-long project of empirical research in psychology with the guidance of a member of the Department of Psychology.

Philosophy:  Focus on philosophy of science, philosophy of mind, philosophy of psychology, philosophy of neuroscience, or philosophy of language, depending on their area of primary specialization. Courses suitable for this program include PHIL 234. Philosophy of Language, PHIL 236. Philosophy of Mind, PHIL 250. Philosophy of the Cognitive Sciences, and PHIL 285. Seminar on Special Topics, which will frequently focus on issues relevant to cognitive science. Students will prepare a research paper (preferably originating in one of the above courses) that demonstrates control of the methodology and knowledge of important issues in their area of specialization.

For adjustments to existing plans, or for examples of ways to meet the secondary specialization, contact the Program Directors (mfulkerson@ucsd.edu or cmwalker@ucsd.edu).

Overview

The program can be summarized in this way:

  1. In the first years, their home department provides basic training within the student's primary specialization.
  2. In the middle years, acquisition of secondary specialization and participation in the Cognitive Science Seminar (Cog Sci 200) and other coursework requirements.
  3. In the final years, dissertation research on a topic in cognitive science, supervised by faculty from the program.
