2012 skin & body senses-perception

  1. 1. SKIN & BODY SENSES
  2. 2. SKIN SENSES  COMPRISED OF:  PRESSURE  TEMPERATURE  PAIN  DETERMINED BY THE NUMBER OF PAIN RECPETORS IN A GIVEN AREA  NECK & BACK OF THE KNEE HAVE MANY
  3. 3. BODY SENSES KINESTHESIS  INFORMS BRAIN ABOUT THE POSITION AND MOTION OF THE BODY VESTIBULAR SENSE  INFORMS THE BRAIN AS TO THE VERTICAL POSITION OF THE BODY
  4. 4. PERCEPTION Does the door swing in or out? Where do you focus your attention?
  5. 5. Muller-Lyer Illusion Which line between the arrows is longer?
  6. 6. 6 Rules of Perception Closure Figure-Ground Perception Proximity Similarity Continuity Common Fate
  7. 7. ClosureThe tendency to perceive a complete or whole figure even when there are gaps in what your senses tell you.
  8. 8. Figure-Ground Perception The perception of figures against a background. Which is which? What we perceive as a figure and what we perceive as a background influences our The Vase or Profile perception perception
  9. 9. Proximity  Nearness of one item to another  People tend to group together visual & auditory events that are near each other
  10. 10. Similarity  Tendency to group together elements that seem alike  Think of similar objects as belonging together
  11. 11. Continuity  Tendency to group stimuli into continuous patterns  People would rather see continuous patterns rather than disrupted onesA third principle of perceptual organization is that of good continuity. This principle is that contours based on smoothcontinuity are preferred to abrupt changes of direction. Here, for instance, we are more likely to identify lines a-b and c-dcrossing than to identify a-d and c-b or a-c and d-b as lines.
  12. 12. Common Fate Tendency to perceive objects that are moving together as belonging together Ex. - if you saw a group of runners it is assumed that they are running to the same place
  13. 13. Stroboscopic Motion  Visual illusion in which the perception of motion is generated by the presentation of a series of stationary images in rapid succession  Flip book  Claymation Movies  “Chicken Run”  Gumby
  14. 14. Depth Perception Monocular Cues for Depth Monocular cues need only one eye to be perceived and make objects on a 2- D surface appear to be 3-D Examples of these cues are perspective, clearness, overlapping, shadows, and motion parallax
  15. 15. Depth Perception Binocular Cues for Depth Binocular cues require both eyes to see the effect
  16. 16. Depth Perception Binocular Cues (Continued) Two cues for depth perception  Retinal Disparity  Convergence Both work related to the closeness of objects to the eyes http://dragon.uml.edu/psych/depth2.html
  17. 17. Perceptual Constancies Size Color Brightness Shape
  18. 18. Size Tendency to perceive an object as being of one size no matter how far away it is  Experience is key
  19. 19. Shape The knowledge that an object has the same shape no matter what angle it is perceived from
