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. Some psychologists believe this dissociation from reality may result from an imbalance between bottom-up and top-down processing — a hypothesis ripe for testing using the hollow mask illusion.

Dima and Jonathan Roiser of University College London wanted to understand why people with schizophrenia aren't fooled.
