Selective Attention
the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.
inattentional blindness
failing to see visible objects when or attention is directed elsewhere.
visual capture
the tendency for vision to dominate the other senses.
gestalt
an organized whole. Gestalt psychologists emphesized our tendency to integrate pieces of information into meaningful wholes.
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 coherant groups
depth perception
the ability to see objects in three dimension 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
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 a quick succession
perceptual constancy
percieving objects as unchanging (having consistent lightness, color, shape, and size) even as illuminating 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 percieve 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 (ESP)
the controversial claim that perception can occur apart from sensory input. Said to include telepathy, clairvoyance, and precognition
parapsychology
the study of paranormal phenomena, including ESP and psychokineses
