Entre la percepción visual de lo posible y lo imposible en pacientes con esquizofrenia

Abstract

Between the visual perception of possibility or impossibility in schizophrenic patients. In the current psychophysics research about schizophrenia, the patient's deficiencies on perceptual processes have been addressed in several works. In relation to the visual perception topic several researches have been carried out relating gestaltic principles with such deficiencies. In the present paper the capacity of schizophrenic patients to discriminate possible from impossible objects was analyzed. Eight possible and impossible figures were used as stimuli. Our hypothesis was that schizophrenic patients would perform worst that controls while perceiving the possibility or impossibility of objects. 13 schizophrenic patients and 11 controls were compared in the execution of a discrimination task. Results show that schizophrenic patients display a bigger difficulty than controls on discriminating possibility or impossibility of objects.
