Abstract

Disgust is a powerful human emotion that hasn`t been extensively studied until recently. Current theories do not coherently explain the function of disgust, nor why such a wide range of stimuli can provoke a similar emotional response. The aim of this study was to explore the hypothesis that the function of disgust is related to pathogen avoidance. 200 individuals completed an experiment with 21 photo stimuli and completed the Three- Domain Disgust Scale (TDDS) and perceived vulnerability to disease questionnaire (PVD). Images of objects holding a potential disease threat were reported as significantly more disgusting than similar images with little or no disease relevance. Females reported higher disgust sensitivity on experiment`s stimuli than males; had higher sensitivity to TDDS pathogen and TDDS sexual disgust; and had higher scores on both PVD Perceived Infectability and PVD Germ Aversion. Disgust sensitivity on stimuli was positively correlated with TDDS pathogen disgust and with PVD Germ Aversion. Reaction time on stimuli was also measured, but results were inconsistent. Our results are in line with the notion that the human emotion of disgust may be an evolved response to objects in the environment that represent threats of infectious disease.
