Perceptual/Optical Illusions
Have you ever experienced a situation in which you were sitting or lying in a dark room and you suddenly “see” an object that is no longer there when you turn on the light? Can the human brain be tricked into seeing something that is not actually there? The simple answer is yes. Sensation is universal and is what our eyes see based on the available stimuli, but perception is little more complex and individualized as it changes based on experience and is what our brain sees and interprets. By arranging a series of colors, images, or patterns strategically, or modifying the way an object is lit, the brain can be tricked into seeing things that do not exist. These tricks are often referred to as perceptual, or optical, illusions.

Suggested Answer: The brains of primates are wired to be uniquely responsive to faces or stimuli that have face-like qualities. This specialized face-recognition system helps us to identify an individual face out of the thousands that we can recognize. However, this ability also leads to false-positives. That is, vague or ambiguous images with face-like features can trigger the brain's face-recognition system, leading us to see faces where they do not exist at all, except in our own mind.
