Description: Efforts to understand disgust are complicated by the wide variety of disgusting stimuli. In an attempt to explain the range of disgusting objects, Rozin and colleagues have suggested that the function of disgust has expanded from an origin in protecting the body from dangerous ingestants to a derived role in protecting the metaphorical soul from dangerous influences. The aim of this research was to test the base of Rozin's taxonomy: the relationship between distaste and disgust. The facial expressions associated with distaste and disgust were measured using electromyography. Activation of the levator labii muscle, which raises the upper lip and wrinkles the nose, was found to be common to expressions of both disgust and distaste. Given that disgust and distaste are associated with similar expressions, it can be inferred that they activate a common behavioural program and thus may be part of a unitary system, as Rozin's taxonomy suggests.
