inattentional blindness
failing to see visible objects when our attention is directed elsewhere.
visual capture:
the tendency for vision to dominate the other senses.
an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.
the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).
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.
retinal disparity:
a binocular cue for perceiving depth: By comparing images from the two eyeballs, the brain computes distance—the greater the disparity (difference) between the two images, the closer the object.
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.
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 (having consistent lightness, color, shape, and size) even as illumination and retinal images change.
perceptual adaptation:
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.
human factors psychology:
a branch of psychology that explores how people and machines interact and how machines and physical environments can be made safe and easy to use.
extrasensory perception:
the controversial claim that perception can occur apart from sensory input. Said to include telepathy, clairvoyance, and precognition.
the study of paranormal phenomena, including ESP and psychokinesis.
selective attention:
the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.
monocular cues:
depth cues, such as interposition and linear perspective, available to either eye alone.
