Show Answers:

  1. the act of converting sensation into neural impulses
    sensory transduction
  2. the smallest amount of stimulus one can detect
    absolute threshold
  3. the minimal difference needed to notice a difference between two stimuli
    difference threshold
  4. this type of threshold is propotional to the stregth of the original stimulus
    difference threshold (radio loud...needs to be louded to notice change)
  5. this type of adaptation allows us to focus on important stimuli
    sensory adaptation
  6. when a babies cry can wake a mother up, but a thunderstorm can not...this is an example of?
    sensory adaptation
  7. this type of processing intakes raw sensory data to the brain, the brain uses all the data to build a perception

    rods for night vision
  14. these eye receptors are used for central and color vision
  15. these eye receptors need more light than their counter part
  16. the regio of our vision where vision is the sharpest
