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