AbstractPrevious studies suggest possible visual-perceptual deficits associated with schizophrenia, and co-existing impairments in attention and visual-perceptual function in people with schizophrenia. This study examines if people with schizophrenia show visual-perceptual difficulty and whether different components of attention, namely sustained attention, selective attention, switching attention and attentional control processing, relate to the visual-perceptual function of people with schizophrenia differently. A total of 94 participants voluntarily participated in this study: 47 of them were diagnosed with schizophrenia and 47 were normal controls. Visual-perceptual abilities were measured by the Hooper Visual Organization Test (HVOT) for visual organization ability and the Judgment of Line Orientation Test (JLOT) for spatial perception and orientation. Tests for measuring different components of attention were also administered. We observed that our clinical participants performed significantly poorer in both the HVOT and the JLOT. We further noticed that nonverbal intelligence had a significant influence on our participants' performance in these two administered tests. Regarding the relationship between attention and visual-perceptual function, our findings indicated that such a relationship existed only among our clinical participants, not the normal controls. The attention control process significantly predicted the performance in the HVOT and switching attention efficiency significantly predicted the performance in the JLOT. © 2004 Elsevier B.V.
