Psychopathy is a constellation of distinct interpersonal (e.g., pathological lying), affective (e.g., lack of remorse), lifestyle (e.g., need for stimulation), and antisocial (e.g., poor behavioral controls) traits that contribute to a deceptive and exploitive personality profile. Current theoretical models attempting to explain the functional impairments and neural systems behind the behavioral profile of the disorder seem to converge on the idea of a fear deficit. The purpose of this essay was to investigate the positive relationship between psychopathy and fear deficits as well as the dysregulation of the limbic system in adults.
