Talk:Hollow-Face illusion

From Wikipedia, the free encyclopedia

You have new messages (last change).

I've removed the following section:


==Why it works==
It works because you can't see a 3D image on a 2D surface (e.g a computer screen), so your brain cannot tell which way the face is pointing.


because the illusion works also in 3D, not only with a picture of the item, as is also said in the text above.

[edit] Moved Original Research to Talk Page

The following text has been moved from the main article:

(Barlow (1997) takes a more ‘reductionist’ view preferring to think of this in terms of redundancies of bottom-up signals from the eyes. I would limit this to very general features, such as properties of edge-signalling giving contrast effects, rather than phenomena attached to particular objects or particular classes of objects, such as faces.)
