Other instances of this spectrum include conduct disorder, oppositional defiant disorder, and antisocial personality disorder. In short, psychopathy seems to entail two distinct facets.
The second facet, sometimes called secondary psychopathy or Factor 2 psychopathy, corresponds to a more impulsive form of aggression, representing an emotional response to negative events (Hare, 1991, 1993). Psychosis is a loss of contact with reality that leads to symptoms like hallucinations, delusions, and disordered thoughts.Psychosis presents itself in disorders like schizophrenia, bipolar disorder, and major depression. Koch (1841-1908) (Figure 2), coined the term psychopastiche, or psychopath, in 1888.The three dimensions of psychopathic personality were moderately correlated (0.54–0.66) and these correlations were primarily mediated by genetic and shared environmental factors.In contrast to research conducted with adolescent and adult twins, we found that both genetic and shared environmental factors influenced psychopathic personality traits in early childhood.It was Philippe Pinel (1745-1826) (Figure 1), the founding father of modern psychiatry, who first described a group of patients afflicted with mania sans délire (insanity without delirium)(Pinel, 1801).
