Across
  1. 1. the system for sensing body orientation and balance, which is located in the semicircular canals of the inner ear
  2. 3. 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
  3. 4. the receptor cells for hearing; these are located in the cochlea and are responsible for changing sound vibrations into neural impulses
  4. 5. 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.
  5. 8. a sound's highness or lowness, which depends on the frequency of the sound wave
  6. 9. the system for sensing the position and movement of individual body parts
  7. 10. the process of organizing and interpreting incoming sensory information
  8. 14. The major organ of hearing; a snail-shaped, bony, fluid-filled structure in the inner ear where sound waves are changed to neural impulses
  9. 16. threshold (just noticeable difference) the minimum amount of difference needed to detect that two stimuli are not the same
  10. 19. diminished sensitivity to constant and unchanging stimulation
  11. 20. a ring of muscle tissue that forms the colored portion of the eye and regulates the size of the pupil
  12. 21. threshold the minimum amount of stimulation needed to detect a particular stimulus
  13. 22. processing information processing that draws on expectations and experiences to interpret incoming sensory information
  14. 23. The light-sensitive surface at the back of the eyeball
  15. 25. nerve the nerve that carries visual information from the eye to the occipital lobes of the brain
  16. 26. focusing conscious awareness on a particular stimulus to the exclusion of others
Down
  1. 2. a theory that predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise)
  2. 6. the adjustable opening in the center of the iris, which controls the amount of light entering the eye
  3. 7. 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.
  4. 11. 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
  5. 12. visual receptor cells located in the retina that can detect only black, white, and gray
  6. 13. the transparent structure behind the pupil that changes shape to help focus images on the retina
  7. 14. the clear, curved bulge on the front of the eye that bends light rays to begin focusing them
  8. 15. information processing that analyzes the raw stimuli entering through the many sensory systems
  9. 17. visual receptor cells located in the retina that can detect sharp details and color
  10. 18. the process by which our sensory systems (eyes, ears, and other sensory organs) and the nervous system receive stimuli from our environment
  11. 24. erve the nerve that carries sound information from the ears to the temporal lobes of the brain
