5 Written questions

5 Matching questions

  1. cochlear implant
  2. opponent-process theory
  3. wavelength
  4. retina
  5. inner ear
  1. a created by Edward Hering; alternative theory used to explain after images; suggest that the retina contains three pairs color receptors or cones-yellow-blue, red-green, black-white; pairs work in opposition (thalamus)
  2. b the light-sensitive inner lining of the back of the eyeball; contains receptor cells (rods/cones)
  3. c The distance from the peak of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from longer/red, shorter/blue
  4. d a device for converting sounds into electrical signals and stimulating the auditory nerve by electrodes threaded into the cochlea
  5. e The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.

5 Multiple choice questions

  1. Diminished sensitivity as a consequence of constant stimulation.
  2. visual receptor cell; located in retina; respond to varying degrees of light and dark; responsible for night vision and peripheral vision
  3. Ernst Weber; the principle that accounts for how one notices the difference threshold for any change must be proportional
  4. snail-shaped structure in the inner ear; contains fluid that vibrate; attach the oval window and basilar membrane
  5. in perception, the ability to adjust to an idea or mind set

5 True/False questions

  1. Depth perceptionthe mental process of sorting, identifying, and arranging raw sensory data into meaningful patterns

          

  2. signal detection theoryIn hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch.

          

  3. middle earsnail-shaped structure in the inner ear; contains fluid that vibrate; attach the oval window and basilar membrane

          

  4. basilar membranea device for converting sounds into electrical signals and stimulating the auditory nerve by electrodes threaded into the cochlea

          

  5. cones
    transparent part of the eye behind the iris; focuses light on the retina (accommodation); change shape to focus on objects;-if object is closed, muscles attach to the land contract to make lens around,-if object is far away, the muscles pull to flatten the lens
