Document Summary
Figure and ground: the organization of visual fields into object (the figures) that stand out in their surroundings. Grouping: organizing the figure into a meaningful form, the perceptual tendency to organize stimuli into coherent groups. Continuity: we perceive smooth, continuous patterns rather than discontinuous ones. Closure: we fill in gaps to create a complete, whole object. Depth perception: the ability to see objects in three dimensions although the images that strike the retina are two-dimensional: allows us to judge distance. Visual cliff: a laboratory device used to measure depth perception in infants and young animals. Monocular cues: used to judge a person 10 or 100 meters away, depth cues, such as interposition and linear perspective available to either eye alone. Sometimes, adult brains are tricked into seeing things that we aren"t really seeing. Phi phenomenon: an illusion of movement created when two or more adjacent lights blink on and off in quick succession.
