Its been quite a while since we last made our post on optical illusion series. But wait is over and Nerds bring you another installment in this series. And thanks to our readers for showing great interest in our previous two post related to it:
Bordering & Framing Illusion:
What are your first observations upon seeing the above two picture? Let me guess: One picture is brighter than other. Am I right? Yes. Well, actually they are not. This is actually how our brain perceives it. When bordered or framed, colors appear to be more brighter. That’s why black lines are commonly used to enhance colors like in stained glasses.
Duck or Rabbit?
This is a DUCK, that’s what you exclaimed at the first sight. But if you pause and ponder upon the image for a while, you will also observe that it is RABBIT. To check this, just rotate the image 90 degree towards right!
Man’s Face or …??
Face of a man or the word LIAR??? Just truthfully tell us how much time it took you to figure it out what it was before you read the clue given by us. You can try this with your friends, bet they will say it is a face of a man upon first sight unless they have seen it already.
Face or Vase?
The above is the picture of a vase created by Danish pschycologist Edgar Rubin in 1915 called Rubin’s Vase. This is the example of cognitive optical illusion. Why optical illusion, well upon first sight it appears to be a simple vase, but when you place it in front of black background, you can clearly see two shaped on the either sider of the vase. The picture given below will clearly give you the comparison.
Which dot is bigger?
The dot in the center on the right is bigger than the one in the center on the left. Amazingly, they are both same. The reason is that the dot in the center on the left is surrounded by bigger dots whihc make it look small and the one on the right in the center is surrounded by smaller and it looks bigger. This is what our brain perceives. Simply put, a 6 ft guy will look small among basket ball players.
Ponzo Illusion:
Are both YELLOW lines of equal size?
On the first sight, you thought that both the yellow lines were not equal, Actually they are! Its explanation is that the perception of the two same sized lines is distorted by pair of converging lines. Even artists make use of this illusion in their drawings.
