  1. 1. A new stimulus must differ at a constant proportion from original stimulus if a change is to be detected.
  2. 4. A type of threshold that's the minimum amount of sensation we can detect.
  3. 6. A kind of hearing loss that results from damage to the middle/inner ear (EX. excessive loud noises).
  4. 7. A type of threshold that's the smallest/weakest amount of change in a sensation we can detect.
  5. 9. The enhancement of one or more sense in response to loss of another sense.
  6. 11. A condition when one sensory system triggers automatic sensations in another.
  7. 12. The process of making meaning out of sensory info.
  8. 13. A mode of info processing where info flows from higher-level structures in brain to lower-level structures.
  9. 14. A theory that detection of sensory stimulus involves some amount of decision making.
  10. 15. A color vision theory that combines both ideas from Trichromatic and Opponent-process theories.
  11. 17. Specialized cells that transform physical energy into nerve impulses.
  12. 18. A decline in sensitivity to a constant stimulus.
  13. 19. The process of converting energy from the environment into nerve impulses.

  1. 2. A mode of info processing where info flows from sensory receptors up to brain.
  2. 3. A kind of hearing loss that results from damage to the eardrums (EX. earwax buildup).
  3. 5. A small area of the retina that's insensitive to light, where the optic nerve leaves the eye.
  4. 8. A snail shaped tube in the inner ear where sound vibration is converted into nerve impulses.
  5. 9. The process of sensing our environment through sensory organs.
  6. 10. The ability to perceive sameness even when the image on retina changes
  7. 16. A tissue thin inner lining made of light-sensitive photoreceptors in the eye.
