IN PREVIOUS publications concerning the electroencephalographic evaluation of primary behavior disorders in children1 and of psychopathic personality in adults,2 we reported correlations with age, sex, family history and antecedent severe illness or cerebral injury of early childhood, which previously had not been considered of etiologic significance. Statistical analyses revealed that electroencephalographic abnormality was unrelated to age and sex but was related to either a "positive" family history or a personal history of cerebral trauma or severe illness. The inference was that the abnormal electroencephalogram was of either genogenic or histogenic origin and thus represented some aspect of the neural limits of the organism. The original number of patients under study has been increased, thus permitting more complete statistical analyses, from which further implications may be drawn. The present communication has this for its purpose.

Because of the consistency of the findings in the two previous studies and the
