Abstract

In the present study. we focused on the ability of suppression of processing in schizophrenic patients, using event-related potentials (ERPs) recorded during a selective attention task. During the task, subjects were required to focus on one ear, counting deviant stimuli, those deviating in duration from a sequence of standard stimuli. We compared amplitude data of two positive components differing in latency elicited by standard stimuli, which reflect suppression of stimulus processing, between schizophrenic patients and normal controls. Significant between-group differences were obtained specifically in the right ear attended condition, suggesting impaired suppression of processing in schizophrenics mediated in the left hemisphere.
