1. Chapter 6 Perception

2. The focusing of conscious awareness on a particular stimulus, as in the cocktail party effect. selective attention

3. inattentional blindness Failing to see visible objects when our attention is directed elsewhere.

4. The tendency for vision to dominate the other senses. visual capture

5. An organized whole. (Our tendency to integrate pieces of information into meaningful wholes.) gestalt

6. The organization of the visual field into objects that stand out from their surroundings. figure-ground

7. The perceptual tendency to organize stimuli into coherent groups. grouping

8. The ability to see objects in three dimensions, although the images that strike the retina are two- dimensional; allows us to judge distance. depth perception

9. A laboratory device for testing depth perception, especially in infants and young animals. visual cliff

10. Depth cues, such as retinal disparity and convergence, that depend on the use of two eyes. binocular cues

11. 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. retinal disparity

12. A binocular cue for perceiving depth; the extent to which the eyes turn inward when looking at an object. The greater the inward strain, the closer the object. convergence

13. Depth cues, such as interposition and linear perspective, available to either eye alone. monocular cues

14. An illusion of movement created when two or more adjacent lights blink on and off in succession. phi phenomenon

15. Perceiving objects as unchanging (having consistent lightness, color, shape, and size) even as illumination and retinal images change. perceptual constancy

16. In vision, the ability to adjust to an artificially displaced or even inverted visual field. perceptual adaptation

17. A mental predisposition to perceive one thing and not another. perceptual set

18. 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. human factors psychology

19. The controversial claim that perception can occur apart from sensory input. (Said to include telepathy, clairvoyance, and precognition.) Extrasensory perception (ESP)

20. The study of paranormal phenomena, including ESP and psychokinesis. parapsychology
