Document Summary
Two important factors in perception of form. Size constancy: ability to recognize that an object remains constant in size regardless of its distance from us or the size of the image on our retinas. Three variables determine ability to maintain size constancy: Past experience with the actual size of an object. Knowledge of the object"s distance from you. Shape constancy: ability to recognize that an object"s shape remains constant regardless of changes in our viewing orientation/angle. Monocular cues: allow depth perception with a single eye. Often used by painters to give the illusion depth. Binocular cues: require two eyes for the perception of depth. Relative size: smaller objects appear farther away. Texture gradients: less-detailed objects appear farther away. Relative height: objects higher in our plane of vision appear farther away. Linear perspective: when parallel lines of objects converge, we perceive distance. Interposition: when one object blocks out another, that object appears closer.
