3 More Optical Illusions You Just Gotta See
We here at Switched have found some great optical illusions online in the past. We are always on the lookout for more, so we were delighted when we came across these three illusions below, thanks to Inside Science News. Just last weekend, these three illusions were chosen as the world's best at a gathering of neuroscientists and psychologists in Naples, Florida. Enjoy!
1. Jerky Curveball - The title says it all. Do this one in two stages. First, stare directly at the spinning ball. On the next pass, try concentrating on the little blue dot to the right of the screen. You will understand immediately how and why this illusion got its name. Pretty trippy.
2. Colored Dove - This one didn't particularly do it for us, but the boys and girls down in Naples thought highly enough of it to rank it number two. Simply stare at the black dot in the middle of the white dove and wait for the red flash. The dove remains colored after the flash thanks to your eyes retaining an afterimage. Interesting? No Doubt. Number two? We have our reservations...
3. Sex Illusion- Sit back, relax, and get your mind out of the gutter. This simple illusion, courtesy of Richard Russell of Harvard University, consists of two pictures of the same person's face. However, each photo has been digitally altered by adjusting the light and dark places in the image, which makes one face look like a boy's and the other a girl's. It's a great effect, and it provides a succinct little study into gender perception. Isn't learning fun? [From: Inside Science News Service, via Livescience]
