Hodges went on to describe work by Moss-Morris and Pétrie who saw medical students' disease as "a normal perceptual process, rather than a form of hypochondriasis." Learning about a disease "creates a mental schema or representation of the illness which includes the label of the illness and the symptoms associated with the condition. Once this representation is formed, symptoms or bodily sensations that the individual is currently experiencing which are consistent with the schema may be noticed, while inconsistent symptoms are ignored."
