binocular cues

depth cues, such as retinal disparity or convergence, that depend on the use of two eyes

retinal disparity

a binocular cue for perceiving depth; by comparing images form the two eyeballs, the brain computes distance- the greater the disparity (difference) between the 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 liner perspective, available to either eye alone

interposition

a monocular cue for perceiving depth; if one object partially blocks our view of another, it is perceived as closer

relative size

a monocular cue for perceiving depth; whereby larger objects are perceived as closer than smaller ones

texture gradient

a monocular cue for perceiving depth; a gradual change from a coarse distinct texture to a fine, indistinct texture signals increasing distance.

relative height

a monocular cue for perceiving depth; objects higher in our field of vision are perceived as farther away

relative motion

a monocular cue for perceiving depth; while you are moving, the nearer the object is, the faster it seems to move

linear perspective

a monocular cue for perceiving depth; the more parallel lines converge, the greater their perceived distance

light and shadow

a monocular cue for perceiving depth; a dimmer object seems farther away

motion perspective

8 monocular cues

phi phenomenon

the illusion of movement created by presenting visual stimuli in rapid succession; an illusion of movement created when two or more adjacent lights blink n and off in quick succession

perceptual constancy

perceiving objects as unchanging (having consistent lightness, color, shape, and size) even as illumination and retinal images change

perceptual adaption

in vision, the ability to adjust to an artificially displaced or even inverted visual field

perceptual set

a mental predisposition to perceive one thing and not another

extrasensory perception

ESP: telepathy, precognition, etc.

parapsychologists

those who study of paranormal phenomena
