Examining the Genetic and Environmental Associations between Autistic Social and Communication Deficits and Psychopathic Callous-Unemotional Traits

Examining the Genetic and Environmental Associations between Autistic Social and Communication Deficits and Psychopathic Callous-Unemotional Traits

Open Access Peer-reviewed Research Article Elizabeth O’Nions , Beata Tick , Fruhling Rijsdijk, Francesca Happé, Robert Plomin, Angelica Ronald, Essi Viding Published: September 1, 2015 https://doi.org/10.1371/journal.pone.0134331 Abstract Background Difficulties in appropriate social interaction are characteristic of both children with autism spectrum disorders and children with callous-unemotional traits (who are at risk of developing psychopathy). Extant experimental studies suggest that the nature of atypical social cognition that characterises these two profiles is not identical. However, ‘empathizing’ difficulties have been hypothesised for…

Improving Negative Emotion Recognition in Young Offenders Reduces Subsequent Crime

Open Access Peer-reviewed Research Article Kelly Hubble, Katharine L. Bowen, Simon C. Moore, Stephanie H. M. van Goozen Published: June 29, 2015 https://doi.org/10.1371/journal.pone.0132035 Abstract Background Children with antisocial behaviour show deficits in the perception of emotional expressions in others that may contribute to the development and persistence of antisocial and aggressive behaviour. Current treatments for antisocial youngsters are limited in effectiveness. It has been argued that more attention should be devoted to interventions that target neuropsychological correlates of antisocial behaviour….

Exaggerated Intergroup Bias in Economical Decision Making Games: Differential Effects of Primary and Secondary Psychopathic Traits

Exaggerated Intergroup Bias in Economical Decision Making Games: Differential Effects of Primary and Secondary Psychopathic Traits

Open Access Peer-reviewed Research Article   Steven M. Gillespie , Ian J. Mitchell, Ian Johnson, Ellen Dawson, Anthony R. 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…

Differentiating Psychopathy from General Antisociality Using the P3 as a Psychophysiological Correlate of Attentional Allocation

Differentiating Psychopathy from General Antisociality Using the P3 as a Psychophysiological Correlate of Attentional Allocation

Open Access Peer-reviewed Research Article Inti A. Brazil , Robbert Jan Verkes, Bart H. J. Brouns, Jan K. Buitelaar, Berend H. Bulten, Ellen R. A. de Bruijn Published: November 16, 2012 https://doi.org/10.1371/journal.pone.0050339 Abstract Recent studies have shown that while psychopathy and non-psychopathic antisociality overlap, they differ in the extent to which cognitive impairments are present. Specifically, psychopathy has been related to abnormal allocation of attention, a function that is traditionally believed to be indexed by event-related potentials (ERPs) of the…
