This course is an introduction to the five basic senses — touch, smell, taste, hearing, and vision. One half of the semester will be devoted to discussing the basic aspects of vision, including the biology of the visual system, color perception, identification of objects, depth perception, and visual illusions. The other half of the semester will be devoted to hearing, touch, smell, and taste. The course will take a functional approach to the senses, describing not only how the senses work, but what the senses are used for, and how impairments in the senses can have a profound influence on everyday life.
