| A | B |
| binocular cues | depth cues, such as retinal disparity and convergence, that depend on the use of two eyes |
| perceptual adaption | in vision, the ability to adjust to an artificially displaced or even inverted visual field |
| perceptual set | a mental predisposition to percieve one thing and not another |
| convergence | a binocular cue for perceiving depth; the extent to which the eyes converge inward when looking at an object |
| interposition | if one object partially blocks our view of another, we perceive it as closer |
| monocular cues | distance cues, such as linear perspective and overlap, available to either eye alone |
| visual cliff | a laboratory device for testing depth perception in infants and young animals |
| 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 capture | the tendency for vision to dominate the other senses |
| grouping | the perceptual tendency to organize stimuli into coherent groups |
| selective attention | the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect |
| perceptual constancy | perceiving objects as unchanging (having consistent lightness, color, shape, and size) even as illumination and retinal images change |
| phi phenomenon | an illusion of movement created when two or more adjacent lights blink on and off in a succession |
| visual agnosia | a syndrome in which all parts of the visual field are seen, but the objects are seen without meaning |
| closure | we tend to ignore gaps to create a complete, whole object |
| figure-ground | the difference between figure (object) and the background |
| relative size | when two objects are similar size, we perceive the smaller one as further away |
| linear perspective | parallel lines appear to converge with distance |
| human factors psychology | a branch of psychology that explores hoew people and machines interact and how machines and physical environments can be adapted to human behaviors |
| parapsychology | the study of paranormal phenomena, including ESP and psychokinesis |
