Investigations into the neurobiology of moral cognition are often done by examining clinical populations characterized by diminished moral emotions and a proclivity toward immoral behavior. Psychopathy is the most common disorder studied for this purpose. Although cocaine abuse is highly co-morbid with psychopathy and cocaine-dependent individuals exhibit many of the same abnormalities in socio-affective processing as psychopaths, this population has received relatively little attention in moral psychology. To address this issue, the authors used functional magnetic resonance imaging (fMRI) to record hemodynamic activity in 306 incarcerated male adults, stratified into regular cocaine users (n = 87) and a matched sample of non-cocaine users (n = 87), while viewing pictures that did or did not depict immoral actions and determining whether each depicted scenario occurred indoors or outdoors. Consistent with expectations, cocaine users showed abnormal neural activity in several frontostriatial regions during implicit moral picture processing compared to their non-cocaine using peers. This included reduced moral/non-moral picture discrimination in the vACC, vmPFC, lOFC, and left vSTR. Additionally, psychopathy was negatively correlated with activity in an overlapping region of the ACC and right lateralized vSTR. These results suggest that regular cocaine abuse may be associated with affective deficits which can impact relatively high-level processes like moral cognition.

The triarchic model of psychopathy replaces a syndromal view of this pathological personality condition with a tripartite trait-based conception, positing three distinct phenotypic dispositions as building blocks for what theorists have traditionally termed psychopathy. The Triarchic Psychopathy Measure (TriPM) offers an efficient means for measuring the three dimensions to facilitate research on the model’s validity. We tested the reliability of the TriPM as well as its convergent and discriminant validity with respect to differing models of personality and other criterion variables reflecting social-emotional adjustment and mental health in an undergraduate participant sample (n = 120). The TriPM evidenced excellent internal consistencies, good test-retest reliability, and strong validity consistent with the triarchic model. We discuss the results with respect to prior research and offer suggestions for future research on the validity of the TriPM and the triarchic model.

Robert D. Hare, C.M. (born 1934 in Calgary, Alberta, Canada) is a researcher in the field of criminal psychology. He developed the Hare Psychopathy Checklist (PCL-Revised), used to assess cases of psychopathy. Hare advises the FBI‘s Child Abduction and Serial Murder Investigative Resources Center (CASMIRC) and consults for various British and North American prison services.
Hare received his Ph.D. in experimental psychology at University of Western Ontario (1963). He is professor emeritus of the University of British Columbia where his studies center on psychopathology and psychophysiology. He was invested as a Member of the Order of Canada on December 30, 2010.
Hervey Milton Cleckley (1903 – January 28, 1984) was an American psychiatrist and pioneer in the field of psychopathy. His book, The Mask of Sanity, originally published in 1941 and revised in new editions until the 1980s, provided the most influential clinical description of psychopathy in the twentieth century. The term “mask of sanity” derived from Cleckley’s belief that a psychopath can appear normal and even engaging, but that the “mask” conceals a mental disorder. By the time of his death, Cleckley was better remembered for a vivid case study of a female patient, published as a book in 1956 and turned into a movie, The Three Faces of Eve, in 1957. His report of the case (re)popularized in America the controversial diagnosis of multiple personality disorder. The concept of psychopathy continues to be influential through forming parts of the diagnosis of antisocial personality disorder, thePsychopathy Checklist, and public perception.
In 1941, Cleckley authored his magnum opus The Mask of Sanity: An Attempt to Clarify Some Issues About the So-Called Psychopathic Personality. This became a landmark in psychiatric case studies and was repeatedly reprinted in subsequent editions. Cleckley revised and expanded the work with each edition published; the second American edition published in 1950 he described as effectively a new book.
The Mask of Sanity is distinguished by its central thesis, that the psychopath exhibits normal function according to standard psychiatric criteria, yet privately engages in destructive behavior. The book was intended to assist with detection and diagnosis of the elusive psychopath for purposes of palliation and offered no cure for the condition itself. The idea of a master deceiver secretly possessed of no moral or ethical restraints, yet behaving in public with excellent function, electrified American society and led to heightened interest in both psychological introspection and the detection of hidden psychopaths in society at large, leading to a refinement of the word itself into what was perceived to be a less stigmatizing term, “sociopath“.

Parental Alienation poisons families and can cause serious harm to children and adults alike. It is a social evil and a form of emotional abuse that is often ignored or denied by child support agencies. James Williams interviews co-authors of a new book called Can’t Explain and touches on the prevalence of psychopathy and narcissism in abuse.
