Across
  1. 4. / the system for sensing the position and movement of individual body parts
  2. 6. Constancy / perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object
  3. 8. Perception / the ability to see objects in three dimensions although the images that strike the retina are two dimensional; allows us to judge distance
  4. 12. Detection Theory / a theory predicting how and when we detect the presence of a faint stimulus (signal) amin background stimulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and level of fatigue
  5. 13. Cues / depth cues, such as interposition and linear perspective, available to either eye alone
  6. 14. / the study of paranormal phenomena, including ESP and psychokinesis.
  7. 18. Sense / the sense of body movement and position, including the sense of balance
  8. 19. / the light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information
Down
  1. 1. 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
  2. 2. / the transparent structure behind the pupil that changes shape to help focus images on the retina
  3. 3. / a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.
  4. 5. Perception (ESP) / the controversial claim that perception can occur apart from sensory input; includes telepathy, clairvoyance, and precognition
  5. 7. Nerve / the nerve that carries neural impulses from the eye to the brain
  6. 9. Spot / the point at which the optic nerve leaves the eye, creating a "blind" spot because no receptor cells are located there
  7. 10. / the central focal point in the retina, around which the eye's cones cluster
  8. 11. (three-color) Theory / the theory that the retina contains three different color receptors - one most sensitive to red, one to green, and one to blue- which, when stimulated in combination, can produce the perception of any color
  9. 14. Phenomenon / an illusion of movement created when two or more adjacent lights blink on and off in quick succession
  10. 15. / the sense or act of hearing
  11. 16. Law / the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount)
  12. 17. / an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes
