This document provides an overview of perception and optical illusions. It defines perception as interpreting information received through the senses to produce meaning, which involves stimuli like sight, sound, texture, smell and taste. The perception process is influenced by Gestalt laws of visual organization, including figure-ground relationships, proximity, closure, and similarity. It also discusses perception constants like size constancy and shape constancy. Optical illusions are then introduced as images that create a perception that does not match reality, using techniques like color, light, and patterns to mislead the brain. Examples of shape, kinetic, and impossible shape illusions are listed.

1. MODULE 3 LESSON 3:
PERCEPTION AND OPTICAL
ILLUSIONS

2. PERCEPTION
TO SEE ≠ TO PERCEIVE
Is the process of selecting and interpreting information
received trough the senses to produce a meaning

3. PERCEPTION PROCESS
Stimuli:
Sight
Sound
Texture
Smell
Taste

4. GESTALT LAWS
It refers to theories of
visual perception
developed by German
psychologists in the
1920s.
These theories
describe how people
tend to organize
visual elements

5. Figure and Background

6. Proximity

7. Closure

8. Similarity

9. Perception Constants: size constancy

10. Perception Constants: shape
constancy

11. Color constancy

12. Ambiguous images
A B

13. OPTICAL ILLUSIONS
Images that create a
perception that in
reality, does not match
the true image.
Optical Illusions can use
color, light and patterns
to create images that
can be misleading to
our brains

14. SHAPE ILLUSIONS

15. KINETIC ILLUSIONS

16. IMPOSSIBLE SHAPES
