'Not' Faces (IMAGE) Ohio State University Caption Researchers have identified a single, universal facial expression that is interpreted across many cultures as the embodiment of negative emotion. The look proved identical for native speakers of English, Spanish, Mandarin Chinese and American Sign Language. It consists of a furrowed brow, pressed lips and raised chin, and because we make it when we convey negative sentiments, such as 'I do not agree,' researchers are calling it the 'not face.'
