Title: Cats don't have beaks! Written by: duddy on Dec 28, 2015 (https://biology-forums.com/gallery/47/4_28_12_15_7_30_24.png) (https://biology-forums.com/index.php?action=gallery;sa=view;id=22806) Can you spot the cat amongst the pigeons? This is Hungarian artist's - Dudolf - latest optical illusion that has some several viewers puzzled. The cause of all this difficulty is likely to have something to do with the way in which the brain processes visual information, by identifying repeating patterns and then using this to automatically fill in the gaps in peripheral vision. This makes it very difficult to spot minor details or irregularities in our visual field without focusing directly on these elements, which means you probably won't see the cat unless you stare straight at it. |
