A STUDY OF CEREBRAL DOMINANCE BY LATERALITY SCORE AND ORDER OF REPORTING IN DICHOTIC LISTENING TEST

The Dichotic listening test was performed on 8 schizophrenics and 8 normal healthy controls. A positive correlation between laterality score and shift of order of reporting from one hemisphere to other was found in light handed scliizophrenics during active stage of the disease. Order of reporting alone may be a factor responsible for this shift of laterality in these patients. Further, on follow-up the abnormalities returned back to normal as these patients recovered. This suggests that schizophrenia is a left hemisphere abnormality with tempcral lobe dysfunction.
