Gives the impression of surfaces receding into the distance. For example, understanding difficult handwriting is easier when reading complete sentences than when reading single and isolated words. However, in the real world, retinal images are rarely seen in isolation (as is possible in the laboratory). Gibson argued strongly against the idea that perception involves top-down processing and criticizes Gregory’s discussion of visual illusions on the grounds that they are artificial examples and not images found in our normal visual environments. Each sense organ is part of a sensory system which receives sensory inputs and transmits sensory information to the brain. Selective perception is a mechanism that allows you to filter the relevant information and avoid a stimuli overload. As clarity of the stimulus (through exposure duration) and the amount of context increased, so did the likelihood of correct identification. The capabilities and limitations of sensory processes 3.
