5 Written questions

5 Matching questions

  1. accomodation
  2. fovea
  3. rods
  4. absolute threshold
  5. bottom-up processing
  1. a analysis that begins with the sensory receptors and works up to the brain's integration of sensory info
  2. b central focal pt. in retina, around which eye's cones cluster
  3. c retinal recpetors that detect black, white and gray; necessary for peripheral and twilight vision when cones don't respond
  4. d minimum stimulation needed to detect a particular stimulus 50% of the time
  5. e process by which eye's lens changes shape to focus near or far objects on thr retina

5 Multiple choice questions

  1. principle that, to be percieved as diff., 2 stimuli must differ by constant minimum percentage
  2. nerve that carries neural impulses from eye to brain
  3. point at which optic nerve leaves the eye, creating a "blind" spot b/c no receptor cells are located there
  4. the process of interpreting info received from our environment
  5. retinal receptor cells near the center of the retina and function in daylight; detect fine detail and give rise to color sensations

5 True/False questions

  1. psychophysicsstudy of relationships b/w physical characteristics of stimuli and our psychological experience of them

          

  2. opponent-process theorytheory that opposing retinal processes enable color vision

          

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

          

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

          

  5. top-down processinganalysis that begins with the sensory receptors and works up to the brain's integration of sensory info
