  1. Do you see, what you think you see?

  2. Traditional Optical Illusions Many of us think of “trick” pictures, Sometimes they are cleverly drawn, Sometimes they require a bit of looking at. Like this one-

  3. How many words did you see? One or two? Look again-

  4. The shape of the letters are familiar enough on top but not on bottom. The mind has to adjust to the configuration to make them into new words. Try this one, how many legs does the elephant have?

  5. How many did you count, 4, 5, or 6? • Want another look?

  6. What do you think? Shout it out- Last look-

  7. 1 2 3 4 5

  8. But that’s not fair you cry, the first leg isn’t a real leg! Pretty clever, eh? None of them are silly, it’s a drawing. Ok, let’s move on. . .

  9. Illusions that work because of the way your brain works These illusions are possible because of the mechanics of your eye and how the brain receives information. Your eye is constantly working. There is no way that your brain can keep up. So, your brain makes short cuts. Here’s a classic one to start with. . .

  10. Müller-Lyer Illusion

  11. In the Müller-Lyer Illusion we “see” different parts of the building being “different” sizes because of the contextual references that are different (think monocular cues). • Because the ‘arrows” on the lines (building corners) either face in or out, we perceive one being further away than the other.

  12. But that’s not all, in order for you to see “everything” your brain fills in gaps and allows you to keep looking. This allows you to “see” details without really “seeing” them- got it? Like this. What shapes do you see?

  13. Did you see two triangles? You did? Look again.

  14. As you can see, there are 6 pie shapes, no triangles. Your brain creates the triangles in the negative space but they are not really there- your mind assumed you wanted to see them. In the Gestalt School this is called “Closure”.

  15. Which line connects to line C, A or B? It’s not cheating, try again. Don’t blurt out your answer, keep it to yourself please.

  16. Are you sure it’s correct? Got an answer? Look again.

  17. Who says B? Who says A? Let’s “C”.

  18. All right, how about this one. The tabletop on the left is clearly longer than the one on the right. Do you agree? Look closely . . .

  19. The tabletop on the right is shorter and fatter than the one on the left. Shall I prove it to you?

  20. Hmmmmm . . . I guess I was wrong, did you see that coming? How ‘bout this one, is the circle in the center of the image a perfect circle?

  21. Similar to closure, the brain doesn’t know what to give more importance to so it gets confused. The circle looks distorted because there are more lines- more lines equal more important. Next category please. . .

  22. Illusions that work because of the way your eye works Your eyes are constantly picking up new information. If they didn’t, the sense would overload and shut down

  23. This is called over-stimulation. It keeps an image from burning into your retina much the same way a computer screen saver protects your monitor. Don’t believe me? Try this. Stare at the center of the next image. What happens to the shading around the dot?

  24. This works because as you keep your eye still, your eye stops sending impulses because the nerves have already been triggered. By the same mechanism your eyes can be “tricked” into seeing things that aren’t there because you have over-stimulated them. This time, stare at the four dots at the center of the image.

  25. Who did you see? Me or some other guy? Here’s another one. Is this shape moving?

  26. The image appears to “shimmer” or move because your eyes are constantly moving. This keeps them from becoming over stimulated- we know what that does. Because the image has such fine lines and arranged so closely together they appear to move as your eye moves

  27. And Finally. . . What category do you think this next “illusion” goes into?

  28. Olny srmat poelpe can raed tihs. I cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdanieg. Thephaonmneal pweor of the hmuan mnid, aoccdrnig  to a rscheearch at Cmabrigde Uinervtisy, mnaes tahtit deosn't mttaer in waht oredr the  ltteers in a wrod are.
