Investigated brain hemisphere laterality of time information among 60 schizophrenics and 60 nonschizophrenics. Duration estimation of a single dark dot presented to the left, center and right visual fields was studied with respect to an auditory warning signal of variable duration. Three conclusions were drawn: First, the relation between posterior and prior time information was shown to be that of inverse variation, and this relation was intact among schizophrenics, Second, time information was lateralized toward the left hemisphere among nonschizophrenics and toward the right hemisphere among schizophrenics, which indicates hemispheric reversal of time information as a characteristic of schizophrenia. Third, such hemispheric reversal of time information was confined to binocular, therefore, bilateral, stimulus input.
