| Descripción: | Theory of mind (ToM) is the knowledge that other people have minds, thoughts, beliefs and values different from our own. Patients with schizophrenia are generally thought to be impaired at tasks requiring this ability. Frith (1992) has proposed that specific signs and symptoms of schizophrenia are associated with dysfunction in ToM ability. The purpose of the present study was to investigate the role of thought disorder in theory of mind and to tease out the electrophysiological correlates of this phenomenon. Participants partook in an intention attribution task, during which event-related potentials (ERPs) were recorded. Patients with high ratings of thought disorder performed worse than those with low thought disorder and significantly worse than normal subjects. ERP results were unexpected as no differences were detected for ERPs on frontal sites. A significant difference in the P600 component was observed on Pz. Possible explanations for parietal activation are discussed. |
