Therefore, our brains instantaneously process the blurry image of Monroe when the object is small and apparently far away, but as it comes closer, our eyes and brain recognise the more detailed image of Einstein.
The farther an object is from us, the blurrier it appears. The trick is that the image of Einstein shows more detail than the image of Monroe. So, in fact, you are seeing both Monroe and Einstein. This is an example of what is called a hybrid image that imposes one image on top of another. The longer you see this image the more it looks like Albert Einstein instead of Marilyn Monroe, so you might think it’s just a skewed photo of the famous physicist. So, as the man walks across the room he appears to grow in size when in reality he’s just moving closer to the camera. The far-left corner is farther from the camera than the far-right corner. However, an Ames room is shaped like a trapezoid. This room toys with our brain’s sense of perspective.Īlmost any room we enter is either square or rectangular-shaped, meaning opposite walls are parallel to each other and meet at 90 degree angles. This is an example of an Ames room that was first invented by American ophthalmologist Adelbert Ames, Jr. When the subjects maintained a steady stare at a single point, the apparent motion ceased. In a 2012 study, researchers at the Barrow Neurological Institute in Phoenix, Arizona, reported that subjects looking at the picture above only saw apparent movement if their eyes were actually moving. The human brain, although highly sophisticated, processes information in a very basic way: As we move our eyes from left to right, we pick up visual cues both directly and in our peripheral vision that our brain then processes piece-by-piece - not continuously.Īnd because our brains process high-contrast elements, like black on white, faster than low-contrast ones, like black on grey, that lapse in mental read time is ultimately what causes the apparent motion. It’s an example of peripheral drift illusion, which refers to any optical illusion that our brains perceive as moving but, in reality, is still. Here are 10 of the craziest optical illusions and how they work:ĭespite the swirling and twirling you think you see, this is a completely still image. They’re called optical illusions, and they can teach us a great deal about how our brain and eyes work together to understand the world around us.
