5 Matching questions

  1. rods
  2. accomodation
  3. Weber's law
  4. parallel processing
  5. top-down processing
  1. a retinal recpetors that detect black, white and gray; necessary for peripheral and twilight vision when cones don't respond
  2. b process by which eye's lens changes shape to focus near or far objects on thr retina
  3. c info processing guided by higher-level mental processes; construct perceptions and experience expectations
  4. d processing of aspects of a problem simultaneously; brain's natural mode of info processing for many functions including vision
  5. e principle that, to be percieved as diff., 2 stimuli must differ by constant minimum percentage

5 Multiple choice questions

  1. amount of energy in a light or sound wave, which we perceive as brightness or loudness determined by a wave's amplitude
  2. point at which optic nerve leaves the eye, creating a "blind" spot b/c no receptor cells are located there
  3. central focal pt. in retina, around which eye's cones cluster
  4. diminished sesnitivty as a consequence of constant stimulation
  5. minimum stimulation needed to detect a particular stimulus 50% of the time

5 True/False questions

  1. bottom-up processinginfo processing guided by higher-level mental processes; construct perceptions and experience expectations

          

  2. retinalight-sensitive inner surface of the eye, containing the receptor rods and cones and layers of neurons that begin processing of visual info

          

  3. opponent-process theoryinfo processing guided by higher-level mental processes; construct perceptions and experience expectations
