A study of theory of mind in paranoid schizophrenia: A theory or many theories?
Social cognitive psychologists (Frith, 1992; Hardy-Baylé et al, 2003) sought to explain the social problems and clarify the clinical picture of schizophrenia by proposing a model that relates many of the symptoms to a problem of metarepresentation i.e. theory of mind (ToM). Given the differ...

Social cognitive psychologists (Frith, 1992; Hardy-Baylé et al, 2003) sought to explain the social problems and clarify the clinical picture of schizophrenia by proposing a model that relates many of the symptoms to a problem of metarepresentation i.e. theory of mind (ToM). Given the differences in clinical samples and results between studies, and considering the wide range of what is considered to constitute ToM, the question is, is there a core function, or is ToM multifaceted with dissociable facets? If there are dissociable dimensions or facets which are affected in patients with paranoid schizophrenia? To answer these questions, a group of 21 individuals diagnosed with paranoid schizophrenia and 29 non-clinical control subjects, were tested on a battery of five different measures of theory of mind. The results confirmed that there was little difference in specificity of three of the tests in distinguishing between the clinical and non-clinical group, but there were important differences in the shared variance between the tests.
