Belief in conspiracy theories: The predictive role of schizotypy, Machiavellianism, and primary psychopathy

Belief in conspiracy theories: The predictive role of schizotypy, Machiavellianism, and primary psychopathy

Open Access Peer-reviewed Research Article Evita March , Jordan Springer   Published: December 3, 2019 https://doi.org/10.1371/journal.pone.0225964 Abstract A conspiracy theory refers to an alternative explanation of an event involving a conspirator plot organised by powerful people or organisations. Belief in conspiracy theories is related to negative societal outcomes such as poor medical decisions and a decrease in prosocial behaviour. Given these negative outcomes, researchers have explored predictors of belief in conspiracy theories in an attempt to understand and possibly manage…

Deliberate self-harm behavior among young violent offenders

Open Access Peer-reviewed Research Article Natalie Laporte , Andrejs Ozolins, Sofie Westling, Åsa Westrin, Eva Billstedt, Björn Hofvander, Märta Wallinius Published: August 17, 2017 https://doi.org/10.1371/journal.pone.0182258 Abstract Deliberate self-harm behavior (DSH) can have profound effects on a person’s quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2)…

Anger under Control: Neural Correlates of Frustration as a Function of Trait Aggression

Open Access Peer-reviewed Research Article Christina M. Pawliczek , Birgit Derntl, Thilo Kellermann, Ruben C. Gur, Frank Schneider, Ute Habel Published: October 18, 2013 https://doi.org/10.1371/journal.pone.0078503 Abstract Antisocial behavior and aggression are prominent symptoms in several psychiatric disorders including antisocial personality disorder. An established precursor to aggression is a frustrating event, which can elicit anger or exasperation, thereby prompting aggressive responses. While some studies have investigated the neural correlates of frustration and aggression, examination of their relation to trait aggression in…

Psychopathy, pain, and pain empathy: A psychophysiological study

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

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…

Neurobiological Correlates in Forensic Assessment: A Systematic Review

Open Access Peer-reviewed Research Article Toon van der Gronde, Maaike Kempes, Carla van El, Thomas Rinne, Toine Pieters Published: October 20, 2014 https://doi.org/10.1371/journal.pone.0110672 Abstract Background With the increased knowledge of biological risk factors, interest in including this information in forensic assessments is growing. Currently, forensic assessments are predominantly focused on psychosocial factors. A better understanding of the neurobiology of violent criminal behaviour and biological risk factors could improve forensic assessments. Objective To provide an overview of the current evidence about…

Default Network Deactivations Are Correlated with Psychopathic Personality Traits

Open Access Peer-reviewed Research Article Tong Sheng , Anahita Gheytanchi, Lisa Aziz-Zadeh Published: September 7, 2010 https://doi.org/10.1371/journal.pone.0012611 Abstract Background The posteromedial cortex (PMC) and medial prefrontal cortex (mPFC) are part of a network of brain regions that has been found to exhibit decreased activity during goal-oriented tasks. 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,…

Validation of the inventory of Callous-Unemotional Traits among school-going adolescents in Malaysia

Open Access Peer-reviewed Research Article Aref Ezrin Mohamad Khalil, Hue San Kuay , Maruzairi Husain , Yee Cheng Kueh Published: February 16, 2023 https://doi.org/10.1371/journal.pone.0276724   Abstract A key component in the study of antisocial behaviour among adolescents is the presence of callous-unemotional (CU) traits. Among the established tools available to measure CU traits is the Inventory of Callous-Unemotional traits (ICU). To date, there is no validated questionnaire to assess CU traits for the local population. Therefore, there is a need to validate…

Manipulating the odds: The effects of Machiavellianism and construal level on cheating behavior

Manipulating the odds: The effects of Machiavellianism and construal level on cheating behavior

Open Access Peer-reviewed Research Article Mariela E. Jaffé , Rainer Greifeneder, Marc-André Reinhard Published: November 14, 2019 https://doi.org/10.1371/journal.pone.0224526 Abstract Values, beliefs, and traits differ across individuals, and these concepts might impact whether individuals choose to engage in (dis)honest behavior. This project focuses on interindividual differences in Machiavellianism, which is defined as a tendency toward cynicism and manipulativeness, and the belief that the ends justify the means. We hypothesized that trait Machiavellianism would predict dishonest behavior. Furthermore, we speculated that some…

Understanding empathy deficits and emotion dysregulation in psychopathy: The mediating role of alexithymia

Understanding empathy deficits and emotion dysregulation in psychopathy: The mediating role of alexithymia

Open Access Peer-reviewed Research Article Matthias Burghart , Alexander H. J. Sahm, Sergej Schmidt, Jan Bulla, Daniela Mier Published: May 8, 2024 https://doi.org/10.1371/journal.pone.0301085 Abstract Psychopathy is a severe personality disorder marked by a wide range of emotional deficits, including a lack of empathy, emotion dysregulation, and alexithymia. Previous research has largely examined these emotional impairments in isolation, ignoring their influence on each other. Thus, we examined the concurrent interrelationship between emotional impairments in psychopathy, with a particular focus on the…
