Illusion of Faces
Our minds are pattern matching machines. It has spent our entire lives, finding and matching patterns in an effort to keep us alive.
Faces are an important thing to recognize, and they are all remarkably similar. We use the features of the eyes, nose, and mouth to discriminate between two faces. We are innately “primed” for the ability to recognize faces. How difficult does it feel to look at my face represented here? Your eyes skip around the face, and some say it makes the experience double vision. It’s hard to just look at my picture for what it is. When a face doesn’t look like we are used to, our mind uses its patterns (historical data of faces) and tries to fill in the blanks.
Because there are two sets of internal features in my picture, they compete with each other, and neither set can win. Our minds can’t settle on the stimuli and make sense of it the way it would with a normal face.
