The F Face
The facial expressions we make when we are scared serve a biological purpose.
“Our hypothesis was that different changes on the face would lead to different amounts of sensory intake,” said Joshua Susskind, a psychology graduate student at the University of Toronto who worked on a study testing the function of facial expressions. “The idea is that fear is for vigilance. You’d expect that changes on the face, such as opening the eyes, would be characteristic of fear, because you’re trying to assess more information in your environment.”
