  6. 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 Clip:“Is Seeing Believing?” Why do the people in this “Illusion Room” appear to change heights as they switch positions? How are our monocular depth cuesbeing misled?

  11. Illusions • Illusions: • Perceptions that misrepresent physical stimuli

  20. 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 scienceconcluded little about this subject?
