Cognitive science, the study of cognitive systems, is a topic of study that cuts across a variety of traditional disciplines. At the UMass Amherst, the Departments of Communication Disorders, Computer Science, Linguistics, Philosophy, and Psychology have been the most visible players in cognitive science. They have shared Sloan Foundation funding in cognitive science, their faculty share several Federal research and training grants, they host the ongoing Five College Faculty Seminar in Cognitive Science, and their graduate students frequently cross departmental boundaries to take courses and do research. Other schools in the Five Colleges also have a rich variety of offerings in cognitive science, and their faculty often participate in the training of UMass Amherst graduate students.
