Open Access Peer-reviewed Research Article David M. Greenberg , Simon Baron-Cohen, Nora Rosenberg, Peter Fonagy, Peter J. Rentfrow Published: October 3, 2018 https://doi.org/10.1371/journal.pone.0203886 Abstract Traumatic events increase the risk of depression, but there is also evidence that adversity can lead to posttraumatic growth, including increased compassion and prosocial behavior. To date there is no empirical research pinpointing childhood trauma to an increase in trait empathy in adulthood. Although somewhat counter-intuitive, this might be predicted if trauma not only increases fear…

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…

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…
