| selective attention | the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect. (Myers Psychology 8e p. 237) |
| inattentional blindness | failing to see visible objects when our attention is directed elsewhere. (Myers Psychology 8e p. 238) |
| Gestalt | an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes. (Myers Psychology 8e p. 242) |
| visual capture | the tendency for vision to dominate the other senses. (Myers Psychology 8e p. 242) |
| figure-ground | the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground). (Myers Psychology 8e p. 243) |
| grouping | a Gestalt idea - the perceptual tendency to organize stimuli into coherent groups. (Myers Psychology 8e p. 243) |
| binocular cues | depth cues, such as retinal disparity and convergence, that depend on the use of two eyes. (Myers Psychology 8e p. 245) |
| 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. (Myers Psychology 8e p. 245) |
| visual cliff | a laboratory device for testing depth perception in infants and young animals. (Myers Psychology 8e p. 245) |
| monocular cues | depth cues, such as interposition and linear perspective, available to either eye alone. (Myers Psychology 8e p. 246) |
| 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. (Myers Psychology 8e p. 246) |
| 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. (Myers Psychology 8e p. 246) |
| perceptual constancy | perceiving objects as unchanging (having consistent lightness, color, shape, and size) even as illumination and retinal images change. (Myers Psychology 8e p. 250) |
| phi phenomenon | an illusion of movement created when two or more adjacent lights blink on and off in quick succession. (Myers Psychology 8e p. 250) |
| perceptual adaptation | in vision, the ability to adjust to an artificially displaced or even inverted visual field. (Myers Psychology 8e p. 256) |
| perceptual set | a mental predisposition to perceive one thing and not another. (Myers Psychology 8e p. 257) |
| 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. (Myers Psychology 8e p. 261) |
| extrasensory perception (ESP) | the controversial claim that perception can occur apart from sensory input. Said to include telepathy, clairvoyance, and precognition. (Myers Psychology 8e p. 264) |
