Introducing the sick face

Research on disgust in neuroscience, medicine, and psychology often relies on a disgust facial expression from a standardized set. Two studies (N = 60 and N = 160) compared this standard disgust face to a new facial expression called the “sick face” posed by three different actors asked to look as if they were sick and about to vomit. Relative to the standard disgust face, the sick face was significantly more likely to be endorsed as disgust, less likely to be endorsed as another emotion, and rated as conveying disgust more intensely. Disgust may not have a facial signal, but various faces may serve as cues to disgust.
