Meanwhile, the American Prison Association had its own definition, in which psychopathic personalities were considered non-psychotic and characterized by failure to adjust to environment, lacking purpose, ambition and proper feelings, while often showing tendencies towards delinquency, lying and various eccentricities, perversions or manias (including dromomania (compulsion to travel or experience new lifestyles), kleptomania (stealing), pyromania (fire-setting) etc.). In the UK the Mental Deficiency Act 1913 included the category of moral imbeciles, who were not intellectually idiots but displayed from an early age an alleged mental defect coupled with alleged vicious or criminal propensities, and on whom punishment has little or no deterrent effect. Cyril Burt and others pointed out that 'psychopathic personality' was used in a broader and somewhat different way in America than in the UK. In the first decades of the 20th century, "constitutional psychopathic inferiority" had become a commonly used term in the US, implying the issue was inherent to the genetics or makeup of the person, an organic disease. As a category it was used to target any and all dysfunctional or antisocial behavior, and in psychiatric categorization it labeled a broad range of alleged mental deviances, including homosexuality. Some courts began to develop "psychopathic laboratories" for the classification and treatment of offenders; the term psychopathic was chosen to avoid the social stigma of "lunacy" or "insanity", while emphasizing variance from normality rather than simply a mental hygiene issue. Nevertheless, at least one such laboratory issued a report on eugenic sterilization initiatives. From the 1930s, "sexual psychopath" laws (a term going back to Krafft-Ebing) started to be implemented in many US states, allowing for the indeterminate psychiatric commitment of sex offenders. From the late 1920s American psychologist George E. Partridge influentially narrowed the definition of psychopathy to antisocial personality, and from 1930 suggested that a more apt name for it would be sociopathy. He suggested that anyone, and indeed groups of people acting together, could be considered sociopathic at times, but that sociopaths – or technically 'essential sociopaths' - were chronically and pervasively so in their motivation and behavior.! In 1933, American Psychiatrist Harry Stack Sullivan first coined the term "Psychopathic child," which is now thought to be the first formulation of autism spectrum disorder, to describe interpersonal deficiency which starts from childhood. Scottish psychiatrist David Henderson published in 1939 a theory of "psychopathic states" which, although he described different types and unusually suggested that psychopaths might not all be criminals, included a violently antisocial type which ended up contributing to that being the popular meaning of the term.
