Chapter 8.3: Perception, Illusions, and ESP Mr. Loeffler Psychology

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.

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

Monocular Depth Cues Monocular Depth Cues: Cues that can be used with a single eye E.g.: Relative Height Interposition – overlapping of images Light and Shadows Texture/Detail – further away = less detail Motion Parallax Linear Perspective-lines converge in the distance Relative Motion

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

Binocular Depth Cues Binocular Depth Cues: Cues that depend upon the movement of both eyes E.g.: Convergence – eyes turn inward to see nearby objects Retinal Disparity – position of your eyes

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 cues being misled?

Perceiving certain objects in the same way regardless of changing angle, distance or lighting
