  1. 3. The light-sensitive surface at the back of the eyeball.
  2. 4. ____ sense The system for sensing the position and movement of individual body parts.
  3. 7. A sound’s highness or lowness, which depends on the frequency of the sound wave.
  4. 8. ____ spot The point at which the optic nerve travels through the retina to exit the eye; the lack of rods and cones at this point creates a small blind spot.
  5. 11. _____ attention Focusing conscious awareness on a particular stimulus to the exclusion of others.
  6. 12. Visual receptor cells located in the retina that can detect sharp details and color.
  7. 13. Visual receptor cells located in the retina that can detect only black, white, and gray.
  8. 14. ____ down processing: Information processing that draws on expectations and experiences to interpret incoming sensory information.
  9. 16. ____ nerve The nerve that carries sound information from the ears to the temporal lobes of the brain.
  10. 19. ____ threshold: (just noticeable difference) The minimum amount of difference needed to detect that two stimuli are not the same.
  11. 20. A transparent structure behind the pupil in the eye that changes shape to focus images on the retina.
  12. 21. ____ nerve The nerve that carries visual information from the eye to the occipital lobes of the brain.
  13. 23. sensory _____ Diminished sensitivity to constant and unchanging stimulation.
  14. 24. ______ threshold: The minimum amount of stimulation needed to detect a particular stimulus.
  15. 26. ______ cells Specialized cells in every sensory system of the body that can turn other kinds of energy into action potentials (neural impulses) that the brain can process.
Down
  1. 1. ______ detection theory: A theory that predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise).
  2. 2. _____ sense The system for sensing body orientation and balance, which is located in the semicircular canals of the inner ear.
  3. 5. _____ theory A theory of color vision that says cones are sensitive to red, green, or blue light—the three colors that combine to create millions of color combinations.
  4. 6. The major organ of hearing; a snail-shaped, bony, fluid-filled structure in the inner ear where sound waves are changed to neural impulses.
  5. 9. ___ cells The receptor cells for hearing; these are located in the cochlea and are responsible for changing sound vibrations into neural impulses.
  6. 10. The process by which sensory systems (eyes, ears, and other sensory organs) and the nervous system receive stimuli from our environment.
  7. 15. The adjustable opening in the center of the iris, which controls the amount of light entering the eye.
  8. 17. A ring of muscle tissue that forms the colored portion of the eye and regulates the size of the pupil.
  9. 18. The process of organizing and interpreting incoming sensory information.
  10. 21. _______ process theory A theory of color vision that says color is processed by cones organized in opponent pairs (red–green, yellow–blue, and black–white); light that stimulates one half of the pair inhibits the other half.
  11. 22. The clear, curved bulge on the front of the eye that bends light rays to begin focusing them.
  12. 25. _____ up processing: Information processing that analyzes the raw stimuli entering through the many sensory systems.
