Psychopathy is studied by social scientists.
It has been suggested that psychopathy is associated with "instrumental aggression", also known as predatory, proactive, or "cold blooded" aggression, a form of aggression characterized by reduced emotion and conducted with a goal differing from but facilitated by the commission of harm
== Mechanisms ===== Psychological ===Some laboratory research demonstrates correlations between psychopathy and atypical responses to aversive stimuli, including weak conditioning to painful stimuli and poor learning of avoiding responses that cause punishment, as well as low reactivity in the autonomic nervous system as measured with skin conductance while waiting for a painful stimulus but not when the stimulus occurs
