A historical review of disgust

Although disgust was identified as a basic emotion 125 years ago (Darwin, 1965), no psychological theory has focused on disgust as a key concept. Although many prominent scientists such as Freud, Darwin, and Ma/son have addressed the topic of disgust in their research, none have focused solely on the causes and consequences of disgust. The purpose of this paper is to evaluate the literature concerning disgust and to demonstrate how disgust is a meaningful concept worthy of major focus in psychological research, theories, and application
