Recent studies have shown that schizophrenia is characterized by visual perceptual deficits, especially in the ability to integrate stimulus details into a global percept. Also, several studies have found amplitude attenuation of the visual P1 component of the event-related brain potential (ERP), probably indicating impaired visual feedforward processing in schizophrenia. However, there is little knowledge on the role of feedbackward processing in this group. This question is of importance, as recent studies indicate that feedback processing is critical in stimulus integration.
