Spatial frequency processing in schizophrenia: trait or state marker?

Imre Kiss1, Zoltán Janka1, György Benedek2, Szabolcs Kéri3.   

Abstract

B. F. O'Donnell et al. found impaired discrimination performances at low and medium spatial frequencies in patients with schizophrenia. In this study, the authors replicated this finding in a group of remitted, unmedicated, and highly functioning outpatients with spared IQ and attentional functions. However, the deficit was restricted to low spatial frequencies (0.5 cycles/degree), which suggests that this deficit is a trait marker of schizophrenia. Copyright 2006 APA, all rights reserved.
