5 Written questions

5 Matching questions

  1. top-down processing
  2. optic nerve
  3. rods
  4. intensity
  5. retina
  1. a retinal recpetors that detect black, white and gray; necessary for peripheral and twilight vision when cones don't respond
  2. b nerve that carries neural impulses from eye to brain
  3. c info processing guided by higher-level mental processes; construct perceptions and experience expectations
  4. d light-sensitive inner surface of the eye, containing the receptor rods and cones and layers of neurons that begin processing of visual info
  5. e amount of energy in a light or sound wave, which we perceive as brightness or loudness determined by a wave's amplitude

5 Multiple choice questions

  1. distance from the peak of one light or sound wave to the peak of the next
  2. central focal pt. in retina, around which eye's cones cluster
  3. minimum diff. b/w 2 stimuli required for detection 50% of the time
  4. principle that, to be percieved as diff., 2 stimuli must differ by constant minimum percentage
  5. nerve cells in the brain that respond to specific features of stimulus, such as shape, angle or movement

5 True/False questions

  1. absolute thresholdminimum diff. b/w 2 stimuli required for detection 50% of the time

          

  2. parallel processingprocessing of aspects of a problem simultaneously; brain's natural mode of info processing for many functions including vision

          

  3. subliminalbelow one's absolute threshold for conscious awareness

          

  4. psychophysicsthe process of interpreting info received from our environment

          

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