Dombrovski Published: December 3, 2020 https://doi.org/10.1371/journal.pone.0243588 Abstract Humans seek admiration to boost their social rank and engage in rivalry to protect it when fearing defeat. Traits such as narcissism and affective states such as depression are thought to influence perception of rank and motivation for dominance in opposite ways, but evidence of the underlying behavioral mechanisms is scant. We investigated the…

It has been argued that more attention should be devoted to interventions that target neuropsychological correlates of antisocial behaviour….

Beech Published: August 8, 2013 https://doi.org/10.1371/journal.pone.0069565 Abstract Psychopathic personality traits are linked with selfish and non-cooperative responses during economical decision making games. However, the possibility that these responses may vary when responding to members of the in-group and the out-group has not yet been explored. We aimed to examine the effects of primary (selfish, uncaring) and secondary (impulsive, irresponsible) psychopathic personality…

Several scholars have argued that early childhood maltreatment impacts the development of psychopathy,…

Back Published: June 15, 2021 https://doi.org/10.1371/journal.pone.0253187 Abstract Body image concerns revolving around body ideals (thin ideal, muscular ideal) are widespread among women. Whereas a stronger preoccupation with ideal physical appearance is often assumed for narcissistic women, previous empirical findings have been mixed. Following a tripartite structure of agentic, antagonistic, and neurotic narcissism facets, we reexamined whether trait narcissism predicted drive for thinness and drive…

Open Access Peer-reviewed Research Article Hélène Villain , Aïcha Benkahoul , Philippe Birmes, Barbara Ferry, Pascal Roullet Published: January 19, 2018 https://doi.org/10.1371/journal.pone.0191563 Abstract Post-traumatic stress disorder (PTSD) is a common consequence of exposure to a life-threatening event. Currently, pharmacological treatments are limited by high rates of relapse, and novel treatment approaches are needed. We have recently demonstrated that propranolol, a β-adrenergic antagonist, inhibited aversive memory reconsolidation in animals. Following this, in an open-label study 70% of patients with PTSD treated…

Open Access Peer-reviewed Research Article Martina Ardizzi , Maria Alessandra Umiltà, Valentina Evangelista, Alessandra Di Liscia, Roberto Ravera, Vittorio Gallese Published: September 29, 2016 https://doi.org/10.1371/journal.pone.0163853 Abstract Facial mimicry and vagal regulation represent two crucial physiological responses to others’ facial expressions of emotions. Facial mimicry, defined as the automatic, rapid and congruent electromyographic activation to others’ facial expressions, is implicated in empathy, emotional reciprocity and emotions recognition. Vagal regulation, quantified by the computation of Respiratory Sinus Arrhythmia (RSA), exemplifies the autonomic…

Open Access Peer-reviewed Research Article Sara Ferreira-Nascimento , Filipa Freire, Diana Prata Published: July 30, 2025 https://doi.org/10.1371/journal.pone.0327764 Abstract Psychopathy is characterized by social impairments that hinder effective societal functioning. It comprises two main dimensions: “Interpersonal-affective” and “Lifestyle-antisocial,” each associated with distinct patterns of traits and central and peripheral neurocorrelates, particularly concerning social salience and oxytocin function. In this review, we systematically identified and synthesized evidence from studies investigating oxytocin’s role in the psychophysiological correlates of emotion recognition across psychopathy dimensions….

TBI can lead to multiple long-term physical, cognitive and emotional sequelae, including post-traumatic stress disorder (PTSD). Intentional violence may further compound the psychological trauma of the event, in a way that conventional outcome measures, like the Glasgow Outcome…
