1
Chapter 8.3Perception, Illusions, and ESP
  • Mr. McCormick
  • Psychology

2
Do-Now(Discussion)
  • What are optical illusions?
  • Why do you think we experience them?
  • Provide an example of one optical illusion that
    you have experienced.

3
Perceptual Organization
  • Gestalt
  • The experience that comes from organizing bits
    and pieces into meaningful wholes

Depth Perception
  • Depth Perception
  • The ability to recognize distances and
    three-dimensionality

7
Monocular Depth Cues
  • Monocular Depth Cues
  • Cues that can be used with a single eye
  • E.g.
  • Relative Height
  • Interposition
  • Light and Shadows
  • Texture/Detail
  • Motion Parallax
  • Linear Perspective
  • Relative Motion

8
Monocular Depth Cues
  • How can you use monocular depth cues
  • to perceive distance in this image?

9
Binocular Depth Cues
  • Binocular Depth Cues
  • Cues that depend upon the movement of both eyes
  • E.g.
  • Convergence
  • Retinal Disparity

10
Video ClipIs Seeing Believing?
  • Why do the people in this Illusion Room appear
    to change heights as they switch positions?
  • How are our monocular depth cues being misled?

11
Illusions
  • Illusions
  • Perceptions that misrepresent physical stimuli

Extrasensory Perception
  • Extrasensory Perception (ESP)
  • An ability to gain information by some means
    other than the ordinary senses
  • Types of ESP
  • Clairvoyance
  • Telepathy
  • Psychokinesis
  • Precognition

21
Review
  • What are Gestalts? What do they imply about
    perception?
  • What are the two ways in which humans perceive
    depth? Provide one example of each.
  • What are illusions? What do they imply about
    perception?
  • What is ESP? Why has science concluded little
    about this subject?

Homework
  • Study for Test
