Psychopathy, pain, and pain empathy: A psychophysiological study

Open Access Peer-reviewed Research Article Sophie Alshukri , Minna Lyons, Victoria Blinkhorn, Luna Muñoz , Nicholas Fallon Published: July 5, 2024 https://doi.org/10.1371/journal.pone.0306461 Abstract The present study examined whether people higher in psychopathy experienced less self-reported and psychophysiological nociceptive pressure than people lower in psychopathy. We also examined whether psychopathy affects empathy for others’ pain via self-reported and psychophysiological measures. Three hundred and sixty-nine students (18–78 years; M = 26, SD = 9.34) were screened for psychopathic traits using the Youth…

Impaired processing of threat in psychopathy: A systematic review and meta-analysis of factorial data in male offender populations

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…

This network is thought to support a baseline of brain activity, and is commonly referred to as the “default network”. Although recent reports suggest that the PMC and mPFC are associated with affective,…
