The aim of this study was to investigate whether a supramodal system or modality-specific systems underlie visual and auditory spatial attention orienting in two groups of schizophrenic patients: youngers and olders. We measured reaction times and percentages of error in a task based on detection of an auditory target preceded by a visual cue, which could appear in the same location of target, divided from it by the vertical visual meridian, or by the vertical head-centered meridian. While a previous study conducted on “normal” subjects (Ferlazzo, Couyoumdjian, Padovani, and Olivetti Belardinelli, 2002) found slower RTs when cued and target locations were at the opposite sides of the head-centered meridian with respect to the visual meridian or any meridan (i.e., in the same location), in schizophrenics this pattern of results was found only for older subjects. This could be due to a substantial reduction of schizophrenic symptoms in older groups, probably as a consequence of a longer treatment (further analyses showed that the age of outbreak desease was not significant different between two groups)
