This document discusses perception and optical illusions. It defines perception as the process of selecting and interpreting sensory information to produce meaning. The perception process involves stimuli from the five senses. Gestalt laws of visual perception are described, including figure-ground relationships, proximity, closure, and similarity. Perception constants like size constancy and color constancy are mentioned. Optical illusions are defined as images that create misleading perceptions that do not match reality, using techniques like color, light, and patterns to trick the brain. Examples of shape, kinetic, and impossible shape illusions are provided.

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

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

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
