  1. 5. The sensory system for taste.
  2. 7. The process of organizing and interpreting sensory information.
  3. 10. The central focal point in the retina, around which the eye's cones cluster.
  4. 11. The process by which the eye's lens changes shape to focus near or far objects on the retina.
  5. 12. The theory that color vision depends on three sets of opposing colors (red-green, blue-yellow, black-white).
  6. 13. The amount of energy in a light or sound wave, which determines the brightness or loudness; related to amplitude.
  7. 14. The minimum stimulus energy needed to detect a particular stimulus 50% of the time.
  8. 15. The theory that we perceive depth by interpreting monocular cues (like light and shadow).
  9. 16. Specialized neurons in the visual cortex that respond to specific features of the stimulus, such as shape, angle, or movement.
  10. 19. The light-sensitive inner surface of the eye, containing the rods and cones.
  11. 21. Visual receptors that detect black, white, and gray; necessary for peripheral and twilight vision.
  12. 22. The minimum difference between two stimuli required for detection 50% of the time. Also called the just noticeable difference (JND).
  13. 23. The sense of smell.
  14. 24. Theory that predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise).
Down
  1. 1. Diminished sensitivity as a consequence of constant stimulation.
  2. 2. The ring of muscle tissue that forms the colored portion of the eye and regulates the size of the pupil.
  3. 3. The basic taste sensations are sweet, sour, salty, bitter, and this one for savory/meaty.
  4. 4. The distance from the peak of one light or sound wave to the peak of the next.
  5. 6. Nerve that carries information from the retina to the brain.
  6. 8. The area of the cerebral cortex that receives input from the eyes.
  7. 9. Visual receptors sensitive to color and fine detail; function in daylight or well-lit conditions.
  8. 17. The conversion of one form of energy into another, like sensory stimuli into neural impulses.
  9. 18. The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount).
  10. 20. The opening in the center of the eye through which light enters.
