Are you ready to take the Hollow Mask Test?

The "Hollow Mask Test" is a tool used in the field of neuropsychology to better identify cases of schizophrenia.

Healthy people fall into the trap of the optical illusion and see the inside of the mask in a convex way as if it were a face seen from the front.

However, as the sensory areas of the brain of schizophrenics work differently, they see the inside of the mask as hollow.
