"Illusion" by Jenna S. Gestalt psychology! This technique is used to teach students about the power of visual perception. Our minds are accustomed to picking up pieces of visual information and organising it into something whole and familiar. Here you see a profile figure as well as the face of a man. What I like about this is that it's the first example I've seen that doesn't simply use a White person as the default image. #socialscience Via Jan Moren - Google+.
