Familiar vs. Unfamiliar Faces (IMAGE)
Caption
Study participants were familiarized with faces surreptitiously, as background images on a supposed memory task. Later, when asked to pick between two faces showing the same objective level of emotion -- 25 percent happy, let's say -- participants said the familiar face looked happier than the unfamiliar.
