Supposedly checks for schizophrenia when you actually see the mask as concave. Very interesting.

This never used to trick me, but since starting meds, I can see the illusion.

yeah since i started stronger meds i cant not see the illusion. not right now at least. i thought this was interesting:
“The Hollow-Face illusion is weaker among people with schizophrenia and other populations with psychotic symptoms perhaps as a result of reduced tendency to interpret any kind of ambiguous 3D object as convex. It appears to be related to current mental state, namely in regard to current positive symptoms, inappropriate affect, and need for structure.[4][5] The illusion seems to strengthen among successfully treated patients”
