[Studies on psychophysiology in Schizophrenia (author's transl)]

The psychophysiological and psychopathological implications are discussed for the finding that absence of electrodermal orienting response to acoustic stimuli was observed among 40% of the schizophrenic patients in two samples. It was found that withdrawal symptomatology and thought disturbance frequently appear among those patients without orienting response. Examples from previous studies are presented which verify deficient or excessive responses of schizophrenics in other physiological variables. It is suggested that extreme psychobiological primary characteristics of schizophrencis be taken into account in psychopharmacological therapy.
