1391 Words6 Pages

One major line of research offers explanations to the development of psychopathy. This line focuses on the biological effect it has on a person that could lead in becoming a psychopath. Past research studies have suggested that when an individual with psychopathic tendency imagine others in pain, brain areas necessary for feeling empathy and concern for others fail to become active and be connected to other important regions involved in affective processing and decision-making.

  • Psychopathy And Sociopathy Inclusion In The Insanity Defense

    259 Words  | 2 Pages

    As it was being debated whether psychopathic diseases would be included in the model insanity standard, the American Law Institute attempted to exclude psychopathic and sociopathic conditions from consideration (Felthous, 2010). Then in 1961, it was declared by the Third Circuit Court of Appeals that sociopathy would be sufficient in order to raise the issue of insanity. However, this issue of psychopathy and sociopathy inclusion in the insanity defense, and the insanity defense in its entirety remains a controversial issue. Since the 1970s, it seems there is a greater interest in restricting and abolishing insanity tests as well as excluding psychopathy from the defense, and that view is still present (Felthous, 2010). According to Felthous (2010), this tension has been long
