Cerebral Dysrhythmia and Psychopathic Personalities

Abstract

Their findings suggest that organic factors should be weighed more heavily in considering the etiology of psychopathic states.The chief psychiatric connotations of psychopathy are widely understood. Cleckley,5 Darling6 and others have suggested that the condition arises from a defective development of the superego, and constitutional factors have been emphasized by Henderson 7 and others. For our purpose, it appeared unwise to deviate from the view that the diagnosis "constitutional psychopathic state" should be made only when the longitudinal study of the patient's personality presents sufficient evidence for the formulation of a valid psychodynamic interpretation of that entity. However, partial manifestations of the psychopathic character, often considered as identical with the condition per se, may occur in

“The wondrous eyes of a new technology”—a history of the early electroencephalography (EEG) of psychopathy, delinquency, and immorality

“…It was crucially dependent on what was deemed normal (see Analysis below). Some researchers responded to this caveat by tightening the criteria for abnormality on the behavioral and the electrophysiological level, resulting in negligible differences between psychopaths and controls (Simon et al, 1946). Generally, more refined criteria for the classification of brain waves could aid to improve accuracy and consistency in the nascent discipline.…”

Psychopathic and criminal behavior.

“…The psychopath is said by some to show abnormalities, either unusually slow or rapid resting waves, sometimes with spikes consequent to hyperventilation tests, in from 50 to 85 per cent of the cases studied (40,62). Simon and others (64), however, in a study of 96 male psychopaths, carefully screened for the exclusion of those with neurological and physical anomalies and well selected on the basis of social histories and clinical evaluations, report that only 28 per cent of their group showed the deviant patterns. Of the "worst" psychopaths in the group, 25 in number, only five showed abnormal tracings.…”
