Assessments of psychopathic traits are used on a routine basis in forensic evaluations across Westernized countries. Despite this, consensus has not yet emerged concerning what exactly are the "core" features of this construct. Moreover, relatively little is known about how practitioners in the field construe this disorder. This study explored perceptions and attitudes regarding psychopathy among individuals working in the forensic mental health system (N = 90) in Sweden. Participants provided prototype ratings of what they considered to be core psychopathy features based on the Comprehensive Assessment of Psychopathic Personality (CAPP), a model that increasingly is the focus of research in North America and Europe. The study protocol also included questions regarding (a) global perceptions and attitudes about a number of aspects of the psychopathy construct (e.g., personal experience, perceived prevalence), and (b) attitudinal scales that assessed perceived correlates of psychopathic traits across a variety of domains (e.g., violence proneness, treatment amenability) and moral judgments and attitudes concerning how psychopathic offenders should be treated within the legal system. The majority of the 33 individual CAPP items and the six CAPP scales were rated as at least moderately prototypical of psychopathy, with Dominance, Self, and Attachment domains obtaining the highest mean ratings. Participants viewed psychopaths as more likely to commit crimes than the average criminal, without being blatantly "evil" people. We believe our results help to advance our understanding of the psychopathy construct by exploring forensic professionals' perceptions of this disorder in general and in relation to the CAPP model specifically.
HighlightsSocial anxiety disorder (SAD) is a common and disabling psychiatric disorder.Support vector machines (SVM) were trained to separate SAD from controls.Neural face processing in the fear network separated SAD patients from controls.Gray matter volume alterations over the whole brain separated SAD from controls.SVM classifiers may be useful for identifying imaging biomarkers of SAD.
Social anxiety disorder (SAD) has been associated with hyper-reactivity in limbic brain regions like the amygdala, both during symptom provocation and emotional face processing tasks. In this functional magnetic resonance imaging study we sought to examine brain regions implicated in emotional face processing, and the connectivity between them, in patients with SAD (n=14) compared with healthy controls (n=12). We furthermore aimed to relate brain reactivity and connectivity to self-reported social anxiety symptom severity. SAD patients exhibited hyper-reactivity in the bilateral fusiform gyrus in response to fearful faces, as well as greater connectivity between the fusiform gyrus and amygdala, and decreased connectivity between the fusiform gyrus and ventromedial prefrontal cortex. Within the SAD group, social anxiety severity correlated positively with amygdala reactivity to emotional faces, amygdala-fusiform connectivity and connectivity between the amygdala and superior temporal sulcus (STS). These findings point to a pivotal role for the fusiform gyrus in SAD neuropathology, and further suggest that altered amygdala-fusiform and amygdala-STS connectivity could underlie previous findings of aberrant socio-emotional information processing in this anxiety disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
