Document Summary
Unit 1: introduction to the perception of form. Distinguishing figure from background is a complex visual function. The whole is greater than the sum of its parts. Believed that people perceive the whole stimulus rather than each individual part. Each thing can be reduced to basic elements. Movies are made from quickly flashing static pictures. Motion is an emergent property of a sequence of pictures. Believed we are either born with these laws of organization or grouping tendencies or that we acquire them very rapidly. Laws that describe how we organize visual input. The ability to distinguish an object from its background in a visual scene. The tendency to group elements that are close together in space. The tendency to fill in gaps in a contour to perceive a whole object. The tendency to group together elements that are physically similar. The ability to perceive a simple, continuous form rather than a combination of awkward forms.
