An historical outline of schizophrenia research is described with the close relationship between psychiatry and psychology. Especially, we focused and discussed on the theory of information processing deficits in schizophrenia generated by Broadbent's information processing model (filter theory of attention). In order to show effective methods to elucidate dynamic and active aspects of schizophrenic pathology, we introduced our psychophysiological researches on smooth pursuit eye movements, saccades and prepulse inhibition using the paradigm of self-stimulation. Finally, we suggest that it is necessary to have collaboration between psychiatrists and psychologists for further fruitful research.
