Episode notes
The Dress Illusion
- The white/gold or black/blue dress controversy illustrates how predictions shape perception.
- Morning people, accustomed to bright light, see white/gold, while night owls see black/blue.
Perception vs. Hallucination
- Perception is anchored to the world through prediction error signals, refining top-down guesses.
- Hallucination is uncontrolled perception, as the brain's machinery is designed for world interaction.
Change Blindness
- Change blindness supports predictive processing; overconfidence in predictions filters out new evidence.
- The brain predicts its own confidence in its predictions, influencing how it processes sensory input.
