5 Matching questions

  1. optic nerve
  2. difference threshold
  3. top-down processing
  4. parallel processing
  5. rods
  1. a nerve that carries neural impulses from eye to brain
  2. b retinal recpetors that detect black, white and gray; necessary for peripheral and twilight vision when cones don't respond
  3. c minimum diff. b/w 2 stimuli required for detection 50% of the time
  4. d processing of aspects of a problem simultaneously; brain's natural mode of info processing for many functions including vision
  5. e info processing guided by higher-level mental processes; construct perceptions and experience expectations

5 Multiple choice questions

  1. the process by which our sensory receptors receive info from our environment
  2. dimension of color that is determined by the wavelength of light; for example, blue and green as colors
  3. point at which optic nerve leaves the eye, creating a "blind" spot b/c no receptor cells are located there
  4. theory that opposing retinal processes enable color vision
  5. principle that, to be percieved as diff., 2 stimuli must differ by constant minimum percentage
