11 Perceptual Illusions
12 Perceptual Organization: Illusory Contours
13 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 a school of psychology founded in Germany in the 1900s that maintained our sensations are processed according to consistent perceptual rules that result in meaningful whole perceptions, or gestalts.
14 Perceptual Grouping Principles Organization: Gestalt grouping principles are at work here.
15 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
16 Perceptual Grouping Principles Organization:
17 Law of Proximity
18 The Law of Similarity
19 The Law of Continuation
20 Perceptual Organization: Closure Gestalt grouping principles are at work here.
21 The Law of Closure
22 Perceptual Organization Figure and Ground--organization of the visual field into objects (figures) that stand out from their surroundings (ground)
23 Goblet or Faces?
24 Faces or Vases?
25 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
26 Perceptual Organization: Depth Perception Visual Cliff a laboratory device for testing depth perception in infants and young animals. It suggests that the ability to perceive depth is at least partially innate.
27 Perceptual Organization: Depth Perception Visual Cliff
28 Perceptual Organization: Depth Perception Illusory Depth
29 Perceptual Organization: Depth Perception Illusory Depth Explanation
30 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
31 Relative Size Perceptual Organization: Depth Perception
32 Perceptual Organization: Depth Perception Interposition

35 Perceptual Illusions
36 Perceptual Illusions
37 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
38 Perceptual Organization: Depth Perception Relative Height
39 Relative Motion
40 Perceptual Organization: Depth Perception Perspective Techniques
41 Linear Perspective
42
43 Perceptual Organization: Depth Perception Light and Shadow
44 In or Out?
45 Motion Perception Phi Phenomenon an illusion of movement created when two or more adjacent lights blink on and off in succession. (Christmas lights)
46 Perceptual Constancy Perceptual Constancy perceiving objects as unchanging even as illumination and retinal image change color shape size
47 Shape Constancy It is hard to tell if the figure on the upper right is a trapezoid or a square slanted backward. If we add texture, the texture gradient helps us see that it is actually a square
48 Perceptual Organization
49 Ponzo Illusion Converging lines indicate that top line is farther away than bottom line
50 Perceptual Organization: Muller- Lyer Illusion
51 Perceptual Organization- Brightness Contrast
52 Autostereogram Another way to create the illusion of depth through binocular stereopsis is with an Autostereogram An autostereogram is formed by superimposing two repeating patterns The two patterns are slightly offset, and when viewed properly, this offset is seen as a binocular disparity
53 Autostereogram
54 Perceptual Organization: Size-Distance Relationship
55 Perceptual Organization: Grouping Principles Impossible doghouse
56 Sensory Restriction: Blakemore & Cooper, 1970 Kittens raised without exposure to horizontal lines later had difficulty perceiving horizontal bars.
57 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
58 Perceptual Set: Schemas What you see in the center is influenced by perceptual set
59 Gore or Clinton?
60 Mona Lisa
61 Mona Lisa
62 Perceptual Set: Context Effects Context Effects our stereotypes about gender or culture can color context.
63 Perceptual Set: Schemas Flying Saucers or Clouds?
64 Is There Extrasensory Perception? Parapsychology the study of paranormal phenomena ESP the controversial claim that perception can occur apart from sensory input. Psychokinesis moving objects with your brain.
65 Is There Extrasensory Perception? Extrasensory Perception controversial claim that perception can occur apart from sensory input Telepathy mind-to-mind communication; one person sending thought to another or perceiving another s thoughts. Clairvoyance perceiving remote events, such as sensing that a friend s house is on fire. Precognition perceiving future events, such as a political leader s death or a sporting event s outcome.
