Antisocial personality disorder is a type of personality disorder characterized by a disregard for the right of others and repeated impulsive, aggressive, manipulative, irresponsible, and cruel behaviors, typically without the guilt or remorse most people would feel in response to such behaviors. Patients with antisocial personality disorder tend not to exhibit increases in skin conductivity in response to emotional or painful stimuli. This is largely attributed to the low-arousal emotional “coldness” typically associated with antisocial personality disorder individuals, as well as with the closely related diagnosis of psychopathy.
