  23. 23. • GESTALT THEORY: three major gestalt laws of perception are discussed: – FIGURE-GROUND DISCRIMINATION IS concerned with how we differentiate between an object and its context. – LAWS OF GROUPING looks at how we associate objects as we perceive them and include concepts such as proximity, similarity, continuation and common region. – GOOD FIGURE (also known as the law of pragnanz) is the concept that strong, simple figures have more appeal to readers than ones that are complicated for the eye to decode. VISUAL PERCEPTION
  24. 24. • CONSTRUCTIVISM: The theory of constructivism has to do with the ways in which we create ideas about the world around us by combining a number of representative images of that world. Important in this theory is the realization that, because we are always adding new images to that amalgamation (i.e. sampling), our perception is constantly in flux. • ECOLOGICAL PERCEPTION: In contract to constructivism, direct perception asserts that viewer and viewed object are one ecosystem instead of two discrete entities.
