Do you feel tired? Or perhaps you are bristling with energy? Check which one is true for you with this easy stress test. The optic illusion in the picture was invented by a Japanese psychology professor Akiyoshi Kitaoka, who says the “rotating snakes” stay perfectly still for calm and relaxed people and move if you are tired and need a nap. However a fast-spinning picture means you’d better get some professional help. Akiyoshi Kitaoka was born August 19, 1961 in Kochi, Japan. He graduated from the University of Tsukuba, where he studied animal psychology (burrowing behavior in rats) and neuronal activity of the inferotemporal cortex in Macaque monkeys. In 1991, Akiyoshi Kitaoka received a PhD in psychology for his studies of visual illusions and visual perception of geometrical shape, brightness and color in motion illusions and other visual phenomena like Gestalt completion and perceptual transparency, based on a modern conception of Gestalt Psychology. He rose to prominence through his “rotating snakes” illusion. Source: Voice of Russia
