Retrograde Amnesia in Petit Mal

In our former research on the alterations of consciousness in petit mal (Jus and Jus, 1960) we were interested in different kinds of anterograde amnesia in petit mal and also devoted some attention to the problem of amnesia. In the present study we have made a more precise analysis of retrograde amnesia in petit mal.We made a comparative analysis of the results of polygraphic registration and introspection. We found this procedure very useful in studying certain psychopathological phenomena. Its value consists in the fact that these psychopathological phenomena explored by introspection can be compared with simultaneously present pathophysiological phenomena explored by polygraphic registration.This method, which may be called introspective-polygraphic phenomenology, can be applied in different experimental variants. They are principally based on reactivity studies. For the analysis of memory alterations in petit mal we carried out some simple experiments which indicated factors deter
