OPTICAL ILLUSIONS

Psychologists know that we see as much with our brains as we do with our eyes. That’s why psychologists are interested in Rorschach Tests, and they’re also interested in Optical Illusions.

The brain is an editor. It tends to allow us to see only one thing at a time. Therefore, the brain often allows us to have only one interpretation of an ambiguous image at a time; however, if the brain shifts to the other meaning of the image, it at the same time tends to lose the first image.

Many optical illusions relate to perspective (near-far, big-little, large-small, etc.) Some of the optical illusions presented in this PowerPoint include the following (often named after the discoverer or inventor of the optical illusion in question): Ames Room, Bending Lines, Boring Figure, Box and Sphere, Color Blind Test, Cornsweet Effect, Ebbinghaus Illusion, Elephant Legs, Gradients Illusion, Hermann Grid, Hidden Messages, Hypnotizing Image, Kanizsa Triangle, Magritte’s Endless Stairs, Moiré’s Illusion, Morpheus Illusion, Muller-Lyer Illusion, Penrose Triangle, Scintillating Grid, Ponzo Illusion, Rabbit-Duck, Refraction Illusion, Ripple Effect, Rotating Circles, Rubin Vase, Sinking Building, Snakes, Spinning Dancer, Spinning Seeds.
