Cognitive science is the study of the ways in which information is acquired and used by humans, other living organisms, and also artificial cognitive systems. The CEU Department of Cognitive Science concentrates on social and biological aspects of human cognition: how learning, processing, and sharing information about and with others takes place, and how computational models of human cognition can be realized in the brain. Students and faculty undertake interdisciplinary research drawing on psychology, neuroscience, philosophy, mathematical modeling, linguistics, and the social sciences. The department focuses on four main areas of research: infant cognitive development, social cognition, cognition and economics, and the emergence and use of internal representations based on sensory perception. The department currently offers one doctoral program.
