5 Matching questions

  1. Young-Helmholtz trichromatic theory
  2. middle ear
  3. rods
  4. basilar membrane
  5. taste buds
  1. a visual receptor cell; located in retina; respond to varying degrees of light and dark; responsible for night vision and peripheral vision
  2. b created by Hermann von Helmholtz; theory of color vision based on additive color mixing; suggest that the retina contains three types of color receptors, cones: red, green, blue
  3. c groups of cells located on the tongue that enable one to recognize different tastes (sweet, sour, bitter, salt)
  4. d A membrane inside the cochlea which vibrates in response to sound and whose vibrations lead to activity in the auditory pathways.
  5. e The chamber between the eardrum and cochlea containing three tiny bones (Hammer, Anvil, and Stirrup) that concentrate the vibrations (conduction) of the eardrum on the cochlea's oval window.

5 Multiple choice questions

  1. Laboratory device for testing depth perception in infants and young animals
  2. The number of complete wavelengths that pass a point in a given time (for example, per second).
  3. Perceiving familiar objects as having consistent color, even if changing illumination alters the wave-lengths reflected by the object
  4. the mental process of sorting, identifying, and arranging raw sensory data into meaningful patterns
  5. the raw data of experience; sensory stimulation; example are eyes only register light energy and ears only register wave energy

5 True/False questions

  1. transductionConversion of one form of energy into another. In sensation, the transforming of stimulus energies into neural impulses.


  2. opponent process theoryThe theory that opposing retinal processes (red-green Christmas, yellow-blue Michigan, white-black) enable color vision.


  3. blind spot
    place on the retina out where the optic nerve leaves the eye, no receptors (rods/cones) are located here


  4. wavelength
    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


  5. foveaThe central focal point in the retina, around which the eye's cones cluster.
