2. What is the modern applications?Insights are applied in VR/AR, AI, design, and understanding neurological visual disorders
3. Why do we see wrong shapes in the Müller‑Lyer illusion?The brain uses the angles at the ends of the lines to guess depth and size. When those angles are changed, the brain misjudges the line length.
4. How can colors trick our eyes in simultaneous contrast?When a color is surrounded by a different color, the brain changes how it looks. This trick shows that we don’t just see colors, we also compare them to what’s around.
