Open Access Peer-reviewed Research Article Petya Kozhuharova, Hannah Dickson, John Tully, Nigel Blackwood Published: October 29, 2019 https://doi.org/10.1371/journal.pone.0224455 Abstract Background Psychopathy is a personality disorder characterised by two underlying factors. Factor 1 (affective and interpersonal deficits) captures affective deficits, whilst Factor 2 (antisocial and impulsive/disorganised behaviours) captures life course persistent antisocial behaviours. Impaired processing of threat has been proposed as an aetiologically salient factor in the development of psychopathy, but the relationship of this impairment to the factorial structure of…
