The emotion attributed to the prototypical "facial expression of disgust" (a nose scrunch) depended on what facial expressions preceded it. In two studies, the majority of 120 children (5-14 years) and 135 adults (16-58 years) judged the nose scrunch as expressing disgust when the preceding set included an anger scowl, but as angry when the anger scowl was omitted. An even greater proportion of observers judged the nose scrunch as angry when the preceding set also included a facial expression of someone about to be sick. The emotion attributed to the nose scrunch therefore varies with experimental context.
Two correlational studies (ns = 400; 90) examined the association of judgments of immorality and disgust (hypothesized in much current research and theory). Across 40 scenarios in Study 1, immorality was positively correlated with negative emotions, especially anger. With anger partialed, disgust was significantly, but weakly, correlated with immorality, r(38) = 0.22, p < 0.05. Study 2 asked whether the immorality-disgust correlation is due to a confound: immoral events often include elements implicitly or explicitly implying pathogens, such as blood or semen. Across 22 scenarios, those implying pathogens were associated with disgust, but those without pathogens, whether moral or immoral, rarely were. We propose that the relation between disgust and immorality is largely coincidental, resulting from (a) using the word disgust to express anger with or even dislike of immoral acts and (b) the presence of incidental elements capable of eliciting disgust.
That facial expressions are universal emotion signals has been supported by observers agreeing on the emotion mimed by actors. We show that actors can mime a diverse range of states: emotions, cognitions, physical states, and actions. English, Hindi, and Malayalam speakers (N = 1200) viewed 25 video clips and indicated the state conveyed. Within each language, at least 23 of the 25 clips were recognised above chance and base rate. Facial expressions of emotions are not special in their recognisability, and it is miming that may be the universal human ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
