Document Summary
Billions of photons/light-rays hit the retina at the back of your eye. Your mind organizes them into powerful, cohesive objects set in space. This process of organizing involves grouping the stimuli together into objects. Notice that, because there are billions of points of light, hitting the retina, there are an almost infinite number of alternative groupings that you can make. Perceptual organization is the study of why the perceptual system chooses one grouping as opposed to the alternatives. The main idea put forward by this school was that the perceptual system groups by using criteria- and these criteria are really aesthetic criteria. Recall that the gestalt approach says that the structure of what you perceive comes from inside your mind; i. e. , by imposing the criteria of grouping. The source of structure is not your mind, but the environment: j. gibson: He proposed what is called the ecological approach to understanding perception.
