Perception

Perception Outline one direct theory of visual perception: Gibson’s theory: Gibson’s mainly focuses on the idea that perception is a lot more biological and that we directly perceive using an optic array (Information is assumed to consist of signals and to be transmitted from the receptors to the brain). Instead of using the brain to interpret things we use the environment in which perception takes place and the activities of the perceiver within that environment. We then use the affordances (such terrain, water, vegetation, etc.) which provide the clues necessary for perception. However this would eliminate the possibility for the different interpretation and mistakes of visual illusions Using this purely bottom up approach to perception means that all objects in the world have a behavioural ‘significance’ for humans and animals. For example a chair is for sitting on, however the meaning to you of the chair can change according to your mood, if you need to reach for a book the chair is for standing on. Research that could support this idea is Palmer (1975). He showed his group of participant’s scenes that were easily recognisable (for example a kitchen). He would then briefly show them 3 separate images of objects, and ask perception, visual, theory, kitchen, illusions, perceptual, objects, participants, gibson’s, gibson, using, support, set, research, perceiver, perceive, need, life, idea, however, good, example, chair, world, view, takes, scene, properly, process, picture, people, organization, one, likely, interpretation
