Across
  1. 3. An organized whole; psychologists in this field emphasize our tendency to integrate pieces into wholes
  2. 6. Analysis that begins with the sensory receptors and works up to the brain’s integration
  3. 8. The light-sensitive inner surface of the eye
  4. 9. Depth cues that depend on the use of two eyes
  5. 10. Theory that the rate of nerve impulses matches the frequency of a tone
  6. 12. The sense of body movement and position, including balance
  7. 15. The central focal point in the retina where cones are concentrated
  8. 17. The system for sensing the position and movement of individual body parts
  9. 18. The ability to see objects in three dimensions
  10. 20. The theory that the retina contains three types of color receptors
  11. 21. The process of organizing and interpreting sensory information
  12. 24. The nerve that carries neural impulses from the eye to the brain
  13. 25. Information processing guided by higher-level mental processes
  14. 27. A mental predisposition to perceive one thing and not another
  15. 28. The minimum stimulation needed to detect a stimulus 50% of the time
  16. 29. The conversion of one form of energy into another, especially sensory input into neural signals
Down
  1. 1. Theory that links pitch we hear with the place where the cochlea’s membrane is stimulated
  2. 2. The process by which sensory receptors receive stimulus energies from the environment
  3. 4. The theory that opposing retinal processes enable color vision
  4. 5. Focusing conscious awareness on a particular stimulus
  5. 7. The controversial claim that perception can occur apart from sensory input
  6. 11. The minimum difference a person can detect between any two stimuli half the time
  7. 13. The point where the optic nerve leaves the eye and no receptor cells are located
  8. 14. Diminished sensitivity to an unchanging stimulus
  9. 16. The principle that, to be perceived as different, two stimuli must differ by a constant proportion
  10. 19. Depth cues available to either eye alone
  11. 22. Retinal receptors that detect fine detail and color; function in daylight or well-lit conditions
  12. 23. Retinal receptors that detect black, white, and gray; important for peripheral and night vision
  13. 26. Theory that the spinal cord contains a neurological “gate” that controls pain signals
