Figure-ground- the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground) Grouping- the perceptual tendency to organize stimuli into coherent groups 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 for testing depth perception in infants and young animals Binocular cues- depth cues, such as retinal disparity and convergence, that depend on the use of two eyes

Unformatted text preview: Retinal disparity- a binocular cue for perceiving depth. By comparing images from the two eyeballs, the brain computes distances- the greater the disparity (difference), between two images, the closer the object Convergence- a binocular cue for perceiving depth, the extent to which the eyes converge inward when looking at an object. The greater the inward strain, the closer the object. Monocular cues- depth cues, such as interposition and linear perspective, available to either eye alone. Phi phenomenon- an illusion of movement created when two or more adjacent lights blink on and off in quick succession Perceptual constancy- perceiving objects as unchanging 9 having consistent lightness, color, shape and size) even as illumination and retinal images change....
