Ten Studies Into Psychopathic Personality concerns ten studies made on psychopathic disorders in Britain from 1958 to 1963. These studies cover 100 subjects who were admitted at the Balderton Hospital in 1958. These studies cover subjects such as diagnostic analysis, E.E.G. technique, parental separation and severity disorder, conscience, and prognosis of psychopaths. Six studies describe work on patient admissions for treatment of psychopathic disorders, while four reports investigate hypotheses through comparison of those admissions to groups of normal, delinquent, and psychopathic individuals. These reports show a continuum in personality disorder from normality, to minor behavioral disorders to extreme psychosis. Some general conclusions note that no evidence exists between direct genetic endowment from parent to psychopathic traits of children, as well as more studies need to clinically define psychopathic behavior from lesser personality disorders. Other conclusions show very little knowledge at hand for effectively treating psychopathic behavior; other results point to differential improvement to different treatments. These studies will interest, psychiatrists, psychologists, behavioral scientists, researchers and academicians dealing with deviant human behavior.
