Across
  1. 3. the height of the wave
  2. 9. To be perceived as different, 2 stimuli must differ by a constant minimum percentage rather than a constant amount
  3. 11. hearing loss caused by damage to the mechanical system that conducts sounds waves cochlea;damage to the middle ear
  4. 13. Visual information is analyzed in terms of the opponent colors;Explains after image
  5. 14. total hearing loss due to damage in the inner ear
  6. 16. a vision defect wherein the eye perceives some colors differently than others
  7. 17. a theory predicting how and when we predict the presence of a faint stimulus aid background stimulation assumes that there is no single absolute threshold and that detection depends partly on a person's experience, expectations
  8. 18. the sense of body movement and position including the sense of balance
  9. 20. Taking in information and trying to make sense of it;Work up to brain's sensory information
  10. 21. Minimum stimulation needed to detect stimulus 50% of the time
  11. 22. Whole Basilar Membrane vibrates at the same rate as sound wave;doesn't explain high pitch
  12. 23. Causes sound to move in waves;snail shaped inner ear part
  13. 24. the number of complete wavelength that pass a point in a given time
  14. 25. the pattern of disturbance caused by the movement of energy traveling through a medium as it propagates away from the source of the sound
Down
  1. 1. the theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows then to pass on to the brain
  2. 2. Past experience to new information;Experience and expectations
  3. 4. Encoding stimulus energy into neural messages
  4. 5. visual illusion in which retinal impressions persist after the removal of a stimulus
  5. 6. Minimum difference can detect between any two stimuli 50% of the time
  6. 7. information occurring under the threshold
  7. 8. encoding several stimuli at once
  8. 10. theory the theory that the retina contains 3 different colors receptors such as red, blue, and green
  9. 12. Unchanging stimulus,Allows focus on informative changes,Eliminates distractions
  10. 15. Different pitches activate different places in Basilar membrane;Explains higher pitch sounds but does not explain lower pitch sounds
  11. 19. the system for sensing the position and movement of individual body parts
