The program in Perception, Brain and Behavior is designed to provide students with the training necessary to conduct research on the sensory aspects of vision and hearing. The faculty members in this area have worked on a wide variety of topics, but their general emphasis has been on the more fundamental mechanisms involved in visual and auditory perception. Students will learn about the behavioral (psychophysical) and physiological techniques best suited for studying sensory mechanisms, and about mathematical modeling of sensory phenomena and systems. A traditional goal of sensory psychology is to explain psychophysical facts in terms of known physiological facts, accordingly, students in the Perception, Brain and Behavior area will be expected to study the literature in both domains. Graduates from Perception, Brain and Behavior will be qualified to work in either academic or industrial settings
