Count the number of faces that you see in the picture above...Here is one of many drawings that challenges your perception and it takes the brain some time to perceive more faces than first observed. The tree and the two people at the bottom are obviously meant to be recognised right away. However, what we see as branches can be analysed and recognised at some point also as faces. While you are searching for faces, the brain tries to find some subtleties in the branches that could be similar to a face. The reason it takes more time to see those faces is because you ask your brain to perceive those obvious branches as something else. Once you see those faces, your are no longer able to ignore them and you cannot see the tree and the faces in the branches at the same time! I'll describe this phenomenon in more detail in later posts. Thus, there are officially 13 faces, but even I didn't see them all...
Also, another one using trees that is nice but more obvious is the cover for the movie Premonition (2007):
I only found ten faces! I really like your site, I feel smarter after reading your posts hehe!
ReplyDeleteSeriously, I'm starting to think that there are only 11 faces maximum and that we are searching for nothing :)
