Hemispheric imbalances masquerading as paranoid and nonparanoid syndromes?

Evidence from psychophysiological and behavioral investigations of lateralization in psychosis separates two clinical syndromes. A speculative model is offered in which the syndromes approximate the clinical features of paranoid compared with nonparanoid patients in investigations in which the groups have been distinguished in the psychology laboratory (Magaro 1980), and encompass the distinction between acute functional psychoses and classical schizophrenia (Kety 1980). A parsimonious account is provided of the hemispheric imbalances of function tht underpin the syndromes.
