This document summarizes key concepts in perceptual organization from psychology. It discusses Gestalt laws of organization, top-down and bottom-up processing, depth perception through binocular disparity and motion parallax, perceptual constancy, motion perception, subliminal perception, extrasensory perceptions, and perceptual illusions. The document was created by Syed Zamurad Abbas Sherazi and focuses on constructing our view of the world through perceptual organization.

4. History and Principles
History 1900s by German psychologists (1923)
To Organize bits and pieces of information
Principles 1. Closure 2. Proximity 3. Similarity 4. Simplicity
The Gestalt Laws of Organization

5. Top-Down and Bottom-up Processing
• Top Down
• Breaking down a stimulus into basic elements
• Allows us to bring experience to bear on
perception
• Bottom up
• From individual components
To the whole perception

6. Depth Perception
Translating 2-D to 3-D
Binocular Disparity
(diff b/w eyes images)
Motion parallax
Binocular
perspective
Brain

7. Depth Perception
More Example

8. Perceptual Constancy
It can mislead us, like.

9. Perceptual Constancy
Moon Size

10. Motion Perception
As the World Turns

11. Perceptual Illusions
The deception of Perception
Visual Errors

12. Subliminal and Extrasensory
Perception
Subliminal Perception
• Perception of messages
• Stimulus- word, sound,
smell
• Drink coke or any
• Major behavior change
Extrasensory Perception (ESP)
• Which does not involve our
known senses.
• 50% united statues
population say right
• 50% say wrong
