Abstract
La teoría de la mente propone que los signos y síntomas de
la esquizofrenia reflejan una disfunción en el sistema cognitivo
dedicado al reconocimiento y control de nuestras propias
intenciones y a la atribuci6n de intenciones a otras personas.
Nuestra pretensi6n es analizar si' los deficits metarepresentacionales
observados en esquizofrénicos se asocian
a su sintomatología. 47 sujetos se seleccionaron para el estudio:
27 esquizofrénicos y 20 sujetos control. Las pruebas utilizadas
fueron: Test de factor "gn, escala PANSS y tarea extensiva de
verbos mentales. Los enfermos se reunieron, según sus signos
y síntomas, en los grupos de: signos conductuales, síntomas paranoides, fenómenos de pasividad y otros síntomas menos
típicos! remisión. Se encontraron dificultades en TM en pacientes
con signos conductuales negativos y positivos. con delirios
paranoides y con características de pa$lvidad; dificultades que
se plasmarán en su discurso. Asimismo. los pacientes con signos
conductuales ejecutaron la tarea peor que los pacientes con
delirios paranoides. El grupo con otros síntomas menos típicos y
en remisión realizaron la tarea de mentalización normalmente.
The theory of mind proposes that the signs and symptoms of schizophrenia reflect. the precise nature of the dysfunction within a cognitive system devoted to the recognition and monitoring of one 's own intentions and the attribution of intentions to others. This study examines the hypothesis that metarepresentational deficits seen in patients with schizophrenia are associated with their symptomatology. Forty- seven people were assessed during this study: twenty- seven patients with a diagnosis of schizophrenia and twenty non-psychiatric controls. Measures: Factor -g" test, PANSS scale and mental verbs extension task. The patients were al/ocated to one of four groups according to their current signs and symptoms: behavioural signs, paranoid symptoms. passivity phenomena and other symptoms! remission. We found metarepresentational problems in patients with negative and positive behavioural signs, paranoid delusions and passivity features and associated with speech disorder. Al so, our psychiatric participants with behavioural signs performed the task significan tI Y more poorly than do patients with paranoid delusions; while the group with other symptoms and those in remission performed the task normally.
