5 Written questions

5 Matching questions

  1. sensory adaptation
  2. absolute threshold
  3. optic nerve
  4. cones
  5. perception
  1. a minimum stimulation needed to detect a particular stimulus 50% of the time
  2. b diminished sesnitivty as a consequence of constant stimulation
  3. c the process of interpreting info received from our environment
  4. d nerve that carries neural impulses from eye to brain
  5. e retinal receptor cells near the center of the retina and function in daylight; detect fine detail and give rise to color sensations

5 Multiple choice questions

  1. principle that, to be percieved as diff., 2 stimuli must differ by constant minimum percentage
  2. the process by which our sensory receptors receive info from our environment
  3. central focal pt. in retina, around which eye's cones cluster
  4. point at which optic nerve leaves the eye, creating a "blind" spot b/c no receptor cells are located there
  5. distance from the peak of one light or sound wave to the peak of the next

5 True/False questions

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

          

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

          

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

          

  4. top-down processinginfo processing guided by higher-level mental processes; construct perceptions and experience expectations

          

  5. difference thresholdminimum stimulation needed to detect a particular stimulus 50% of the time
