    1. 1. Myers’ PSYCHOLOGY (7th Ed) Chapter 6 Perception James A. McCubbin, PhD Clemson University Worth Publishers
    2. 2. Perception  Selective Attention focus of conscious awareness on a stimulus particular
    3. 3. Change Blindness
    4. 4. Perceptual Illusions
    5. 5. Perceptual Illusions
    6. 6. Perceptual Illusions
    7. 7. Perceptual Illusions
    8. 8. Perceptual Illusions
    9. 9. Perceptual Illusions
    10. 10. Perceptual Illusions
    11. 11. Perceptual Organization: Gestalt  Visual Capture  tendency for vision to dominate the other senses  Gestalt--an organized whole  tendency to integrate pieces of information into meaningful wholes
    12. 12. Perceptual Organization: Gestalt  Grouping  the perceptual tendency to organize stimuli into coherent groups  Grouping Principles      proximity--group nearby figures together similarity--group figures that are similar continuity--perceive continuous patterns closure--fill in gaps connectedness--spots, lines, and areas are seen as unit when connected
    13. 13. Perceptual Organization: Illusory Contours
    14. 14. Perceptual Organization  Figure and Ground--organization of the visual field into objects (figures) that stand out from their surroundings (ground)
    15. 15. PerceptualOrganization: Grouping Principles
    16. 16. PerceptualOrganization: Closure  Gestalt grouping principles are at work here.
    17. 17. PerceptualOrganization: Grouping Principles  Gestalt grouping principles are at work here.
    18. 18. Perceptual Organization: Depth Perception  Depth Perception  ability to see objects in three dimensions  allows us to judge distance  Binocular cues  retinal disparity  images from the two eyes differ  closer the object, the larger the disparity  convergence  neuromuscular cue  two eyes move inward for near objects
    19. 19. Perceptual Organization: Depth Perception Visual Cliff
    20. 20. Perceptual Organization: Depth Perception  Monocular Cues  relative size  smaller image is more distant  interposition  closer object blocks distant object  relative clarity  hazy object seen as more distant  texture coarse --> close fine --> distant
    21. 21. Perceptual Organization: Depth Perception Relative Size
    22. 22. Perceptual Organization: Depth Perception Interposition
    23. 23. Perceptual Organization: Depth Perception  Monocular Cues (cont.)  relative height  higher objects seen as more distant  relative motion  closer objects seem to move faster  linear perspective  parallel lines converge with distance  relative brightness  closer objects appear brighter
    24. 24. Perceptual Organization: Depth Perception Relative Height
    25. 25. Perceptual Organization: Depth Perception Perspective Techniques
    26. 26. Perceptual Organization: Depth Perception Light and Shadow
    27. 27. Perceptual Organization: Depth Perception Illusory Depth
    28. 28. Perceptual Constancy  Perceptual Constancy  perceiving objects as unchanging even as illumination and retinal image change  color  shape  size
    29. 29. Perceptual Organization
    30. 30. Perceptual Organization: Depth Perception Illusory Depth Explanation
    31. 31. Perceptual Organization: Muller-Lyer Illusion
    32. 32. Perceptual Organization: Size-Distance Relationship
    33. 33. Perceptual OrganizationBrightness Contrast
    34. 34. PerceptualOrganization: Grouping Principles  Impossible doghouse
    35. 35. Sensory Restriction: Blakemore & Cooper, 1970  Kittens raised without exposure to horizontal lines later had difficulty perceiving horizontal bars.
    36. 36. Perceptual Interpretation  Perceptual Adaptation  (vision) ability to adjust to an artificially displaced visual field  prism glasses  Perceptual Set  a mental predisposition to perceive one thing and not another
    37. 37. Perceptual Set: Schemas  What you see in the center is influenced by perceptual set
    38. 38. Perceptual Set: Schemas Flying Saucers or Clouds?
    39. 39. Perception and the Human Factor  Human Factors Psychology  explores how people and machines interact  explores how machine and physical environments can be adapted to human behaviors
    40. 40. Perceptual Set: Human Factors 10 Altitude (thousands of feet) Pilot’s perceived descent path 8 6 4 Altitude looks this much higher 2 Actual descent path 0 20 18 16 14 12 10 8 6 4 Distance from runway (miles) 2
    41. 41. Is There Extrasensory Perception?  Extrasensory Perception  controversial claim that perception can occur apart from sensory input  telepathy  clairvoyance  precognition  Parapsychology  the study of paranormal phenomena  ESP  psychokinesis
