ABSTRACT

The author's investigated whether NK's deficit also affected the intensity of his reaction to plausible disgust-provoking scenarios, using a questionnaire testing the experience of disgust; additional questionnaires investigated his experience of anger and fear. NK's scores for the anger and fear questionnaires did not significantly differ from the controls' mean scores. In contrast, his overall score for disgust was significantly lower than the controls. It is important to investigate the fundamental predictions of the multi-modal hypothesis. These are, first, that brain injury affecting the areas identified by functional imaging research should produce a selective impairment in recognizing signals of disgust, and second, that this impairment should affect the recognition of disgust signals from other modalities than just the face. NK also showed a significant or borderline reduction in his scores for five of eight disgust subscales, scoring at or near the minimum score on the categories of food, animals, body products, envelope violation and death.
