Disgust
Is an emotion that is typically associated with things that are regarded as unclean, inedible, infectious, or otherwise offensive. For example, "I am disgusted by the stench and sight of that heap of rotting viscera." In The Expression of the Emotions in Man and Animals, Charles Darwin wrote that disgust refers to something revolting. Disgust is experienced primarily in relation to the sense of taste (either perceived or imagined), and secondarily to anything which causes a similar feeling by sense of smell, touch, or vision. Musically sensitive people may even be disgusted by the cacophony of inharmonious sounds. Disgust is one of the basic emotions of Robert Plutchik's theory of emotions. It invokes a characteristic facial expression, one of Paul Ekman's six universal facial expressions of emotion. Unlike the emotions of fear, anger, and sadness, disgust is associated with a decrease in heart rate.
Disgust may be further subdivided into physical disgust, associated with physical or metaphorical uncleanliness, and moral disgust, a similar feeling related to courses of action. For example; "I am disgusted by the hurtful things that you are saying." Moral disgust should be understood as culturally determined; physical disgust as more universally grounded. In The Hydra’s Tale: Imagining Disgust, Robert Rawdon Wilson discusses moral disgust as an aspect of the representation of disgust. He does this in two ways. First, he discusses representations of disgust in literature, film and fine art. Since there are characteristic facial expressions (the clenched nostrils, the pursed lips), as Darwin, Ekman and others have shown, they may be represented with more or less skill in any set of circumstances imaginable. There may even be “disgust worlds” in which disgust motifs so dominate that it may seem that entire represented world is, in itself, disgusting. Second, since people know what disgust is as a primary, or visceral, emotion (with characteristic gestures and expressions), they may imitate it. Thus, Wilson argues, contempt is, for example, acted out on the basis of the visceral emotion, disgust, but is not identical with disgust. It is a “compound affect” that entails intellectual preparation, or formatting, and theatrical techniques. Wilson argues that there are many such “intellectual” compound affects, such as nostalgia and outrage, but that disgust is a fundamental and unmistakable example. Moral disgust, then, is different from visceral disgust, more conscious and more layered in performance.
Brain
Functional MRI experiments have revealed that the anterior insula in the brain is particularly active when experiencing disgust, when being exposed to offensive tastes, and when viewing facial expressions of disgust.
