Presentation Transcript

  1. SKIN & BODY SENSES

  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. 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 12/1

  4. PERCEPTION

  5. Rules of Perception

  6. Closure The tendency to perceive a complete or whole figure even when there are gaps in what your senses tell you

  7. Figure-Ground Perception • The perception of figures against a background

  8. Figure-Ground Perception

  9. Proximity • Tendency to group together visual & auditory events that are near each other

  10. Proximity

  11. Similarity • Tendency to group together elements that seem alike

  12. Similarity

  13. Continuity • A third principle of perceptual organization is that of good continuity. This principle is that contours based on smooth continuity are preferred to abrupt changes of direction. Here, for instance, we are more likely to identify lines a-b and c-d crossing than to identify a-d and c-b or a-c and d-b as lines.

  14. Continuity • Tendency to group stimuli into continuous patterns

  15. Common Fate • Tendency to perceive objects that are moving together as belonging together

  16. 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

  17. 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 • Ex. Artists using perspective, clearness, overlapping, shadowing, texture

  18. Depth Perception • Binocular Cues for Depth • Binocular cues require both eyes to see the effect

  19. Perceptual Constancies

  20. Size • Tendency to perceive an object as being of one size no matter how far away it is

  21. Color • Tendency to perceive an object is equally bright even when the intensity of the light around it changes • Ex. – Shirts in the movie theatre

  22. Brightness • Tendency to perceive an object as being equally as bright even when the intensity of the light around it changes

  23. Shape • The knowledge that an object has the same shape no matter what angle it is perceived from

  24. Shape Constancy

  25. VISUAL ILLUSIONS

  26. Muller-Lyer Illusion

  27. more illusions
