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. In healthy viewers, the illusion is so powerful that even when aware of the illusion see video below , they are unable to see the concave face — the mind just flips it back.

Many neuroscientists believe we have brain regions dedicated to processing faces, and some brain injuries can leave patients unable to recognize faceseven schizophrenia gif their vision and other memories remain intact.

Schizophrenia is a psychiatric disorder characterized by a distorted perception of reality and bizarre behavior. While the exact cause of schizophrenia is not known, multiple biological, psychological and social factors are thought to play parts in the development of the disease. Males have a 1. Patients with schizophrenia have a mortality ratio of 2. Most of these deaths are attributable to suicide and presence of co-morbid physical health conditions 1. There is sturdy evidence that complications of birth and pregnancy have a significant yet modest effect in increasing the risk of persons developing schizophrenia 7.

Diagnosis of schizophrenia involves ruling out other mental health disorders and determining that symptoms are not due to substance abuse, medication or a medical condition. Determining a diagnosis of schizophrenia may include:. Schizophrenia requires lifelong treatment, even when symptoms have subsided. Treatment with medications and psychosocial therapy can help manage the condition. In some cases, hospitalization may be needed. A psychiatrist experienced in treating schizophrenia usually guides treatment. The treatment team also may include a psychologist, social worker, psychiatric nurse and possibly a case manager to coordinate care.

Dima and Roiser analyzed the fMRI data using a relatively new technique called dynamic causal modeling, which allowed them to measure how different brain regions were interacting during the task. This powerful expectation overrides visual cues, like shadows and depth information, that indicate anything to the contrary. Description Schizophrenia brain large. Many neuroscientists believe we have brain regions dedicated to processing faces, and some brain injuries can leave patients unable to recognize faces , even though their vision and other memories remain intact. But patients with schizophrenia are undeterred by implausibility: They see the hollow face for what it is. In patients with schizophrenia, no such strengthening occurred. Dima thinks when healthy subjects see the illusion, which is somewhat ambiguous, their brains strengthen this connection such that what they expect — a normal face — becomes more influential, overpowering the actual, though unlikely, visual information.

Schizophrenia and schizoaffective disorder are scary words to a lot of people but knowing that psychotic episode is like might help alleviate that.. They assume that those of us who have these illnesses are violent and that the voices we hear tell us to kill people. People do not need to fear people with schizophrenia or schizoaffective disorder or their psychotic episodes.
