A verbal and a visuospatial recall task were compared for discriminating power, using the matched-tasks methodology. These tasks were administered to long-hospitalized schizophrenics. No evidence of a differential deficit, that is, better recall of either the verbal or the visuospatial materials, emerged in the patients. The results replicate a former finding showing no difference between verbal and visuospatial recall in schizophrenics, using memory tasks which were less sensitive as left- and right-hemisphere measures and a non-verbal task less affected by verbal mediation. This replication questions the assumption that the hemispheric differences observed in schizophrenics affect such memory tasks.
