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,…

Open Access Peer-reviewed Research Article Luca Passamonti , Graeme Fairchild, Alex Fornito, Ian M. Goodyer, Ian Nimmo-Smith, Cindy C. Hagan, Andrew J. Calder Published: November 7, 2012 https://doi.org/10.1371/journal.pone.0048789 Abstract Objective Previous research suggested that structural and functional abnormalities within the amygdala and orbitofrontal cortex contribute to the pathophysiology of Conduct Disorder (CD). Here, we investigated whether the integrity of the white-matter pathways connecting these regions is abnormal and thus may represent a putative neurobiological marker for CD. Methods Diffusion Tensor…

Open Access Peer-reviewed Research Article Ryan Smith ,Anne E. Chuning, Colin A. Tidwell, John J. B. Allen, Richard D. Lane Published: December 22, 2022 https://doi.org/10.1371/journal.pone.0277475 Abstract It is unclear at present whether psychopathic tendencies are associated with lower or higher levels of emotional awareness (EA). Given that psychopathy includes a proficiency for manipulating others, one might expect an elevated ability to identify and use information about others’ emotions. On the other hand, empathic deficits in psychopathy could arise from reduced…

This study examines the production of facial emotional expressions of male inpatients with ASPD in a forensic hospital compared with a control group…

Open Access Peer-reviewed Research Article Samuel J. West , Elena Psederska, Kiril Bozgunov, Dimitar Nedelchev, Georgi Vasilev, Nicholas D. Thomson, Jasmin Vassileva Published: April 14, 2023  https://doi.org/10.1371/journal.pone.0283866 Abstract Psychopathy comprises antagonistic personality traits and antisocial behaviors that are associated with critical outcomes for the individual and society (e.g., violent behavior). Since its inception, impulsivity has been theorized as a core feature of psychopathy. Research supports this assertion, yet psychopathy and impulsivity are both multifaceted constructs. As such, the associations commonly…

Open Access Peer-reviewed Research Article Joseph H. Manson , Matthew M. Gervais, Gregory A. Bryant Published: May 2, 2018 https://doi.org/10.1371/journal.pone.0196729 Abstract Little is known about people’s ability to detect subclinical psychopathy from others’ quotidian social behavior, or about the correlates of variation in this ability. This study sought to address these questions using a thin slice personality judgment paradigm. We presented 108 undergraduate judges (70.4% female) with 1.5 minute video thin slices of zero-acquaintance triadic conversations among other undergraduates (targets:…

Voineskos Published: August 20, 2013 https://doi.org/10.1371/journal.pone.0072375 Abstract Psychopathic offenders show a persistent pattern of emotional unresponsivity to the often horrendous crimes they perpetrate. Recent studies have related psychopathy to alterations in white matter. Therefore, diffusion tensor imaging followed by tract-based spatial statistics (TBSS) analysis in 11 psychopathic offenders matched to…
