Across
  1. 3. receptor cells in the retina responsible to night vision and perception of blindness
  2. 4. ability to screen out sensory information and focus on only a small portion
  3. 6. the difference between 2 stimuli must differ from a constant proportion, not a constant amount
  4. 8. wavelength of light wave
  5. 9. process where our eyes sense light and change it to neural messages that our brain can handle
  6. 13. area of the retina that is the center of the visual field
  7. 14. theory that pitch is determined by the location of the greatest vibration of the basilar membrane
  8. 17. people won't notice a change in scenery after a brief interruption
  9. 21. minimum difference between 2 stimuli that can be detected at least 50% of the time
  10. 22. intensity of light wave
  11. 23. receptor cells in the retina responsible for color
  12. 24. place on the retina where there are no receptors
Down
  1. 1. vibrating membrane in cochlea of the inner ear; it contains receptors for sound
  2. 2. the lining of the eye that contains receptor cells that are sensitive to light (transduction occurs here)
  3. 5. part of ear that carries sound waves into the ear also called auditory canal
  4. 7. part of ear containing fluid that vibrates (where sound waves are converted to neural impulses)
  5. 10. theory that pitch is determined by frequency with which hair cells in the cochlea fire
  6. 11. the transparent protective coating over the front part of the eye
  7. 12. transparent part of eye inside the pupil that focuses on light onto the retina
  8. 14. small opening in the iris which light enters
  9. 15. person's ability to know the position and movement of your body parts
  10. 16. a person's diminishing sensitivity to a stimulus
  11. 18. part of ear that vibrates due to sound waves
  12. 19. minimum stimulation needed to detect a stimulus 50% of the time
  13. 20. colored part of eye
