James J. Gibson

James Jerome Gibson (January 27, 1904–December 11, 1979), was an American psychologist, born in McConnelsville, Ohio, who received his Ph.D. from Princeton University's Department of Psychology, and is considered one of the most important 20th century psychologists in the field of visual perception. In his classic work The Perception of the Visual World (1950) he rejected the then fashionable theory of behaviorism for a view based on his own experimental work, which pioneered the idea that animals 'sampled' information from the 'ambient' outside world. He studied the concept of optical flow (later published as part of his theory of affordance). According to Gibson, one determines the optical flow (which can be described as the apparent flow of the movement of objects in the visual field relative to the observer) using the pattern of light on the retina. The term 'affordance' refers to the opportunities for action provided by a particular object or environment. This concept has been extremely influential in the field of design and ergonomics: see for example the work of Donald Norman who worked with Gibson, and has adapted many of his ideas for his own theories.

In his later work (such as, for example, The Ecological Approach to Visual Perception (1979)), Gibson became more philosophical and criticised cognitivism in the same way he had attacked behaviorism before. Gibson argued strongly in favour of direct perception and direct realism (as pioneered by the Scottish philosopher Thomas Reid), as opposed to cognitivist indirect realism. He termed his new approach ecological psychology. He also rejected the information processing view of cognition. Gibson is increasingly influential on many contemporary movements in psychology, particularly those considered to be post-cognitivist.

I seem to be, to my surprise, a member of a large profession. There are some 20.000 psychologists in this country alone, nearly all of whom have become so in my adult lifetime. They are all prosperous. Most of them seem to be busily applying psychology to problems of life and personality. They seem to feel, many of them, that all we need to do is to consolidate our scientific gains. Their self-confidence astonishes me. For these gains seem to me puny, and scientific psychology seems to me ill-founded. At any time the whole psychological applecart might be upset. Let them beware!

Gibson died in Ithaca, New York. He was married to fellow psychologist Eleanor J Gibson.
