You can learn a lot about the way a person feels just by looking at her face. Researchers have identified eight specific facial expressions that are consistent across cultures and languages around the world. The latest addition to this list was added in March of 2016, and it is called the "not face."
The "not face" is a combination of anger, disgust, and contempt, and is expressed on the face when a person doesn't like something. "To our knowledge, this is the first evidence that the facial expressions we use to communicate negative moral judgment have been compounded into a unique, universal part of language," said Aleix Martinez, a cognitive scientist and professor at Ohio State University. The "not face" joins the list of the seven already-known universal facial expressions: disgust, anger, contempt, happiness, sadness, surprise, and fear. See what the first seven expressions look like in the video below.
