PERSON IDENTIFICATION AND SELF-CONCEPT IN THE DELUSIONAL MISIDENTIFICATION SYNDROME - A CASE-STUDY

This study on a delusional misidentification patient with both Fregoli symptoms and intermetamorphosis investigates the cognitive structure of others and of the self-representations with a new clustering method (HICLAS conjunctive model). Results show that this patient, free from face recognition disorders, shows severe structural anomalies in the mapping of misidentified others, and of the self. Disturbances in the cognitive structure and person identification are discussed in reference to a psychopathological explanation of the misidentification syndrome.
