Princeton, New Jersey, and a fellow of the Center for Advanced Study in the Behavioral Sciences at Stanford University. Gibson was elected into the National Academy of Sciences in 1967. Gibson received honorary doctorates by Edinburgh and Uppsala Universities. Gibson died in Ithaca, New York on December 11, 1979. He was 75 years old. Major contributions and works Gibson's approach to visual perception The question driving Gibson's research on perception was "how do we see the world as we do?". This instigated his empirical research, the environment, and how the individual experiences said environment. There were two primary ways in which James J. Gibson reformed the way psychology views perception. The first is that the templates of our stimulation are affected by a moving organism. This was shown through his research on optic arrays. Secondly, he formulated the idea of three-dimensional space being conceptual. To Gibson, perception is a compilation of the person's environment and how the person interacts with it. James Gibson's major contributions throughout his career were published in three of his major works: The Perception of the Visual World (1950), The Senses Considered as Perceptual Systems (1966), and The Ecological Approach to Visual Perception (1979). Much of Gibson's work on perception derives from his time spent in the U.S. Army Air Force. Here, he delved into thoughts on how imperative perception is on daily functions. His work may be the first to show a distinct difference between types of perception. Form perception, on one hand, is a display of two static displays, whereas object perception, involves one of the displays to be in motion. Gibson laid down the base for empirical perception research throughout his lifetime. He did work on adaptation and inspection of curved lines, which became a precursor for perceptual research later. His basic work rejected the perspective that perception in and of itself is meaningless, he instead argued meaning is independent of the perceiver. He claimed that the environment decides perception, and that meaning is in what the environment "affords" the observer. Major works 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,
