Many illusions exploit the brain's tendency to make assumptions based on limited visual information, misinterpreting reality.
When we see ambiguous figures, our minds wander between interpretations.
Geometric patterns are strategically placed to create depth, movement, and even nonexistent objects.
These visual stimuli are ambiguous, so the brain fills in gaps, sometimes surprising us.
Though entertaining, these optical illusions reveal the complexities of human cognition.
Psychologists and neuroscientists can investigate how people perceive and react to these visual puzzles to learn about the complex relationship between the eyes and brain.
Identifying the hidden number '20' in 5 seconds is the real test, which requires eagle-eye precision.
