- 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.
