Objective: To investigate the characteristics of brain laterality in patients with childhood onset schizophrenia. Methods: The study employed a dichotic Chinese word listening test(DL) as a chief measure and WISC-R as an assistant measure to examine 16 patients and 20 normal children as controls. Results: DL indicated that the patients differed from the controls in ear advantages and their performances were significantly poorer than the controls in left ear. The performances of the patients on WISC-R showed that their PIQ was significantly lower than VIQ. Conclusion:The patients with childhood onset schizophrenia differed from the controls in brain laterality. They might be involved with right hemisphere impairment.
