How Optical Illusions Trick Your Brain

~60 min · 15 stations

How Optical Illusions Trick Your Brain is a self-paced learning path in Visual Arts & Photography, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify why vision requires active mental processing; explain how eyes capture incoming light waves; define the brain's tendency to predict sensory input.

The Conductor

Welcome to the track where we decode the tricks your eyes play on your mind. Mind the gap between what you see and what is real as we pull out of the station.
