Perceiving the Affordances is a personal history and intellectual autobiography of Eleanor Gibson, the groundbreaking research psychologist who was influential in the founding of the theory of perceptual development. It is also a biography of her husband, James J. Gibson, who was a major perceptual theorist and the founder of the ecologically-oriented theory of perception. This is the story of their lives together and how each came to make particular contributions. This book is of interest to people who study perception, perceptual development, infancy, developmental psychology, and the history of psychology.
