Interoception, categorization, and symptom perception
View through CrossRef
Medical practice and the disease model importantly rely on the accuracy assumption of symptom perception: patients’ symptom reports are a direct and accurate reflection of physiological dysfunction. This implies that symptoms can be used as a read-out of dysfunction and that remedying the dysfunction removes the symptoms. While this assumption is viable in many instances of disease, the relationship between symptoms and physiological dysfunction is highly variable and, in a substantial number of cases, completely absent. This chapter considers symptom perception as a form of unconscious inferential somatic decision-making that compellingly produces consciously experienced symptoms. At a mechanistic level, this perspective removes the categorical distinction between symptoms that are closely associated with physiological dysfunction and those that are not. In addition, it brings symptom perception in accordance with general theories of perception. Some clinical implications to understand and treat symptoms poorly related to physiological dysfunction are discussed.
