The Ecological Approach to Visual Perception: Classic Edition

This book, first published in 1979, is about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.

The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.

James J. Gibson (1904–1979) is one of the most important psychologists of the 20th century, best known for his work on visual perception. He received his Ph.D. from Princeton University and his first major work was The Perception of the Visual World (1950) in which he rejected behaviorism for a view based on his own experimental work.

In his later works, including The Ecological Approach to Visual Perception (1979), Gibson became more philosophical and criticized cognitivism in the same way he had attacked behaviorism before, arguing strongly in favor of direct perception and direct realism, as opposed to cognitivist indirect realism. He termed his new approach "ecological psychology".

Gibson’s legacy is increasingly influential on many contemporary movements in psychology, particularly those considered to be post-cognitivist.
