Newscientist also covered this. They have a couple more masks to look at http://www.newscientist.com/article/dn16911-schizophrenics-s...

#12Am I the only one who has to always look up the definition (w/ example image) for concave and convex to differentiate them?

I always think that concave goes in, like a cave.

#14I love the irony that sufferers of a disease "characterized by hallucinations, delusions", see the actual visual information while healthy viewers are utterly unable to see it.
And this: "Schizophrenia patients, meanwhile, may be unable to modulate this pathway, accepting the concave face as reality." is just too ironic, considering that the concave face is reality.
Maybe Schizophrenics are not the delusional ones.

This is really interesting. What more am I missing out from the "real" world?. If there wasn't an "authority" telling me that this face is concave I'll call anyone telling otherwise crazy.

this is exactly what I thought, too
I think we all labor under certain types of illusions on a daily basis - i.e. we ignore the dangers of driving because we have the illusion of control. If we thought about all of the permutations and repercussions of every action it might paralyze us. The mechanisms that we use to allow us to function day-to-day probably dull our senses.

The way I think about it: our brains create perception by combining raw observations with expectations derived from a mental model built on experience, in a process similar to a Kalman filter. Most of the time, the correction based on the mental model helps, such as when an object is partially obscured. Cases like the concave face are false positives for normal people, where experience overrides percpetion. Schizophrenics weight the observations more heavily than the predictions, so they are less likely to experience false positives, but I would expect them to be consequently more likely to experience false negatives (ie. perceiving things too literally, in spite of logic).

#18I remember reading and article/post/whatever a while back that said that some natives/tribes somewhere didn't see optical illusions. The implication was that it might be a product of more industrialized living.
( I may be confusing this a bit here. The first part may have been an article, and the second part may have been part of an HN discussion on it. )

#19Earlier quoted context omitted.
Contrary to popular belief, schizophrenia is not the same thing as dissociative identity disorder/multiple personality disorder. (Which is I believe what you were suggesting with that joke.) From Wikipedia: Schizophrenia is a mental disorder characterized by a disintegration of the process of thinking and of emotional responsiveness. It most commonly manifests as auditory hallucinations, paranoid or bizarre delusions…
"dissociative identity disorder/multiple personality disorder" has been all but dropped by mainstream psychology. It's considered to be an artifact explained as being induced by a number of factors including attention seeking, desire to please therapist, extreme hypochondria and mimicry.
Whether or not it has been dropped by mainstream (source?) - you paint dissociative identity disorder in such a poor light - choosing only to focus on characteristics that make it controversial. I think you'll find that in fact there is simply a lack of consensis amongst psychologists for its basis - which happens to be the case for many 'disorders' in this arena.

#20"Schizophrenics aren’t the only ones who see the concave face — people who are drunk or high can also ‘beat’ the illusion." I had a three beers watching the video, and the first revolution was a concave face. When the next revolution came I saw the illusion and now the illusion is so powerful I can't see it as concave face anymore. I hope that rules me out as schizofrenic...
Wait. Who wrote this.
... back to the books for you.
