The word disgust may refer to more than one emotion

Contrary to a common presupposition, the word disgust may refer to more than one emotion. From an array of 3 facial expressions (produced in our lab), participants (N = 44) in Study 1 selected the one that best matched 11 types of emotion-eliciting events: anger, sadness, and 9 types of disgust (7 types of physical disgust plus moral disgust and simply feeling ill). From an array of 4 facial expressions (two from Matsumoto & Ekman, 1988; two produced in lab), participants (N = 120) in Study 2 selected the one that best matched 14 types of disgust-eliciting events (8 physical and 6 moral). In both studies, the modal facial expression for physical disgust was the "sick face" developed by Widen, Pochedly, Pieloch, and Russell (2013), which shows someone about to vomit. The modal facial expression for the moral violations was the standard disgust face or, when available, an anger face. If facial expression is a constituent of an emotion, physical disgust and moral disgust are separate emotions.
