In the hollow mask illusion, viewers perceive a concave face like the back side of a hollow mask as a normal convex face. The illusion exploits our brain's strategy for making sense of the visual world: uniting what it actually sees — known as bottom-up processing — with what it expects to see based on prior experience — known as top-down processing. This powerful expectation overrides visual cues, like shadows and depth information, that indicate anything to the contrary. But patients with schizophrenia are undeterred by implausibility: They see the hollow face for what it is. About seven out of Americans suffer from the disease, which is characterized by hallucinations, delusions, and poor planning.
