Document Summary
1920s and 1930s: group of psychologists in germany believed that the whole is different than the sum of its parts: believed people perceive the whole stimulus rather than putting together a collection of the discrete parts. Eg. movie: motion is an emergent property of the sequence of pictures: not continuous movement. Perception of the movie is more than collection of thousands of still photographs: if you looked at each photograph rather than all together it is not as good. Did not just believe whole was greater, they also proposed laws of organization. Gestalt principles: laws that describe how we organize visual input. 6 gestalt principles: figure ground ability to determine what part of a visual scene is part of object and what is background. Some pictures are easy to tell if in foreground or background, but some pictures such as the goblet illusion can be reversible: proximity says that elements that are close together in space tend to belong together.
