  1. 1. the number of complete wavelength that pass a point in a given time
  2. 10. the height of the wave
  3. 12. Encoding stimulus energy into neural messages
  4. 16. 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
  5. 17. Minimum stimulation needed to detect stimulus 50% of the time
  6. 18. the pattern of disturbance caused by the movement of energy traveling through a medium as it propagates away from the source of the sound
  7. 19. encoding several stimuli at once
  8. 20. total hearing loss due to damage in the inner ear
  9. 21. the system for sensing the position and movement of individual body parts
  10. 22. a vision defect wherein the eye perceives some colors differently than others
  11. 23. hearing loss caused by damage to the mechanical system that conducts sounds waves cochlea;damage to the middle ear
  12. 24. Past experience to new information;Experience and expectations
Down
  1. 2. theory the theory that the retina contains 3 different colors receptors such as red, blue, and green
  2. 3. Taking in information and trying to make sense of it;Work up to brain's sensory information
  3. 4. Minimum difference can detect between any two stimuli 50% of the time
  4. 5. Unchanging stimulus,Allows focus on informative changes,Eliminates distractions
  5. 6. the theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows then to pass on to the brain
  6. 7. Whole Basilar Membrane vibrates at the same rate as sound wave;doesn't explain high pitch
  7. 8. the sense of body movement and position including the sense of balance
  8. 9. information occurring under the threshold
  9. 11. Causes sound to move in waves;snail shaped inner ear part
  10. 13. visual illusion in which retinal impressions persist after the removal of a stimulus
  11. 14. Visual information is analyzed in terms of the opponent colors;Explains after image
  12. 15. To be perceived as different, 2 stimuli must differ by a constant minimum percentage rather than a constant amount
  13. 19. Different pitches activate different places in Basilar membrane;Explains higher pitch sounds but does not explain lower pitch sounds
