People that score high on psychopathic traits are less likely to yawn contagiously

Considerable variation exists in the contagiousness of yawning, and numerous studies have been conducted to investigate the proximate mechanisms involved in this response. Yet, findings within the psychological literature are mixed, with many studies conducted on relatively small and homogeneous samples. Here, we aimed to replicate and extend upon research suggesting a negative relationship between psychopathic traits and yawn contagion in community samples. In the largest study of contagious yawning to date (N = 458), which included both university students and community members from across 50 nationalities, participants completed an online study in which they self-reported on their yawn contagion to a video stimulus and completed four measures of psychopathy: the primary and secondary psychopathy scales from the Levenson Self-Report Psychopathy Scale (LSRPS), the psychopathy construct from the Dirty Dozen, and the Psychopathic Personality Traits Scale (PPTS). Results support previous findings in that participants that yawned contagiously tended to score lower on the combined and primary measures of psychopathy. That said, tiredness was the strongest predictor across all models. These findings align with functional accounts of spontaneous and contagious yawning and a generalized impairment in overall patterns of behavioral contagion and biobehavioral synchrony among people high in psychopathic traits.

Connectome-based model predicts individual psychopathic traits in college students

Background: Psychopathic traits have been suggested to increase the risk of violations of socio-moral norms. Previous studies revealed that abnormal neural signatures are associated with elevated psychopathic traits; however, whether the intrinsic network architecture can predict psychopathic traits at the individual level remains unclear. Methods: The present study utilized connectome-based predictive modeling (CPM) to investigate whether whole-brain resting-state functional connectivity (RSFC) can predict psychopathic traits in the general population. RS functional magnetic resonance imaging data were collected from 84 college students with varying psychopathic traits measured by the Levenson Self-Report Psychopathy Scale (LSRP). Results: We found that RSFC of the negative networks predicted individual differences in total LSRP and secondary psychopathy scores but not primary psychopathy score. Particularly, nodes with the most connections in the predictive connectome anchored in the prefrontal cortex (e.g., anterior prefrontal cortex and orbitofrontal cortex) and limbic system (e.g., anterior cingulate cortex and insula). In addition, the connections between the occipital network (OCCN) and cingulo-opercular network (CON) served as a significant predictive connectome for total LSRP and secondary psychopathy score. Conclusion: CPM constituted by whole-brain RSFC significantly predicted psychopathic traits individually in the general population. The prefrontal cortex and limbic system at the anatomic level and the CON and OCCN at the functional network level plays a special role in the predictive model-reflecting atypical executive control and affective processing for individuals with elevated psychopathic traits. These findings may provide some implications for early detection and potential intervention of psychopathic tendency.

Psychopathy and Occurrence of Gambling Problems: The Role of Gambling Protective Strategies and Urgency

Background Psychopathy has been an increasing area of clinical and personality research and is associated with numerous problematic outcomes, including pathological gambling, though this area of research is limited. The most common conceptualization of psychopathy is a two-factor model of primary and secondary psychopathy, with primary psychopathy comprising more interpersonal traits and secondary psychopathy encompassing more antisocial behaviors. Previous research has linked psychopathy to greater urgency and lower utilization of harm reduction strategies. Objectives The current study examines the relationship between primary psychopathy, secondary psychopathy, and problematic gambling, as well as the possible mechanisms of these relationships. Method College student gamblers ( n = 308) completed surveys on psychopathy, impulsivity, protective behavioral strategies regarding gambling, and possible gambling problems. Results Primary psychopathy was inversely related to gambling protective behavioral strategies (PBS) and secondary psychopathy was positively associated with higher levels of urgency. Secondary psychopathy, via urgency, was a strong predictor of whether an individual will experience gambling problems, while primary psychopathy via PBS better predicts the number of gambling problems one experiences. Conclusion This study extends an overall under-researched area of gambling and personality and highlights the importance of delineating different factors of psychopathy regarding problematic gambling outcomes.

Psychopathy Profiles and Personality Assessment Inventory Scores in a Sex Offender Risk Assessment Field Setting

A growing body of research suggests there are identifiable psychopathy subtypes among offenders scored on Hare’s Psychopathy Checklist–Revised (PCL-R; Hare, 2003). We used latent profile analysis to examine the generalizability of these subtype findings to PCL-R scores ( N = 615) assigned in a sex offender risk assessment field setting and to examine how offender subtypes differ on measures of comorbid psychopathology, risk, and treatment amenability from the Personality Assessment Inventory. Consistent with prior research, we identified four subtypes when using PCL-R scores from all offenders: Prototypic psychopathy ( n = 239, 38.9%), callous-conning ( n = 154, 25.0%), sociopathic ( n = 96, 15.6%), and general offenders ( n = 126, 20.5%). Prototypic and sociopathic subtypes exhibited the highest levels of comorbid psychopathology and risk for potential violence. We identified classes consistent with primary ( n = 66, 36.7%) and secondary ( n = 114, 63.3%) psychopathy among offenders with PCL-R total scores ≥ 25, and found higher levels of comorbid psychopathology and potential for violence among those in the secondary psychopathy class. Findings provide support the generalizability of existing PCL-R subtype findings to field scores and show how those with similar PCL-R total scores may differ on scores from commonly used multiscale inventories.

Psychopathy, criminal social identity, and criminal network among murderers, attempted murderers, recidivists and first-time incarcerated juveniles from Pakistan

Background: The purpose of the current study was to examine the differences in primary and secondary psychopathy scores, criminal social identity dimensions (cognitive centrality, in-group affect, and in-group ties), and criminal network between four groups of juvenile offenders: murderers, attempted murderers, recidivistic nonhomicidal offenders, and firsttime nonhomicidal offenders. Participants and procedure: Self-reported data were collected among 725 male youth offenders (Mage = 16.47 years) incarcerated in four prisons in Pakistan. Results: The results revealed no significant differences in scores between the four groups of youth offenders on any of the measured variables. Conclusions: It appears that psychosocial selfreported measures may not be effective in discriminating among youth prison populations.

Executive Dysfunction Associated With the Primary Psychopathic Features of Borderline Personality Disorder

Purpose: The aim of the present study is to investigate whether the presence of psychopathic features in BPD is related to dysfunction in executive functions and other neuropsychological functions in these patients.Methods: 82 patients diagnosed with borderline personality disorder and 54 control subjects were studied through clinical and neuropsychological evaluation protocols and the Levenson Psychopathy Inventory.Results: BPD patients showed significantly higher scores on both primary (F1) and secondary (F2) global rates of psychopathy, than controls. The results for these patients also showed a statistically significant association between high scores in primary psychopathy and deficits in executive functions. However, no associations were found between the scores of secondary psychopathy and executive dysfunction.Conclusion: Primary psychopathic features present in patients with BPD are associated with patterns of executive dysfunction. It would therefore be interesting to investigate the role of cognitive rehabilitation in the empathy dysfunctions within these disorders.

Is Narcissism a Slow Life History Strategy Indicator?: The Answer Depends on the LHS Instrument

The dark triad (DT) traits are differentially related to psychometrically assessed life history strategy (LHS), such that psychopathy is strongly associated with a faster LHS, whereas narcissism appears to be, if anything, a slow LHS indicator. However, the research supporting these generalizations has been based largely on undergraduate samples in which LHS has been measured using the Arizona Life History Battery (ALHB; or its short version the Mini-K), an instrument that arguably lacks adequate coverage of low-extroversion content linked to a slower LHS. In this study, 929 U.S. MTurk workers completed a set of DT instruments, a 10-item Big Five Inventory, a 42-item version of the ALHB (K-SF-42), and the life history rating form (LHRF), which is less weighted toward high extroversion content than the ALHB. Factor analysis of the DT instruments yielded factors corresponding to callousness, secondary psychopathy, and socially adaptive narcissism (leadership/authority and grandiose exhibitionism). Callousness and secondary psychopathy were fast LHS indicators with respect to both LHS instruments. Socially adaptive narcissism appeared as a slow LHS indicator with respect to the K-SF-42 but as a fast LHS indicator with respect to the LHRF. Variation in extroversion accounted entirely for the K-SF-42’s positive association with socially adaptive narcissism. This study suggests that narcissism’s apparent status as a slow LHS indicator may be more a matter of measurement than of substance.

The influence of stressful life events, psychopathy, and their interaction on internalizing and externalizing psychopathology

© 2018 Elsevier B.V. Exposure to stressful life events increases risk for both internalizing and externalizing psychopathology, but less is known about moderators of the association between stressful life events and psychopathology. The present study examined the influence of stressful life events, psychopathy, and their interaction on internalizing and externalizing psychopathology in 3877 individuals from the community. We hypothesized that (1) exposure to stressful life events would be a transdiagnostic risk factor for psychopathology, (2) primary and secondary psychopathy would be differentially associated with internalizing psychopathology, and (3) primary psychopathy would moderate the association between stressful life events and internalizing psychopathology. Confirming existing findings, our results were consistent with the first and second hypotheses. In contrast to our third hypothesis, primary psychopathy was not associated with stressful life events in childhood, inconsistently associated with stressful life events in adolescence, and did not moderate the association between stressful life events and internalizing psychopathology. Furthermore, stressful life events across development were associated with secondary psychopathy and internalizing and externalizing psychopathology. We also found similar associations between stressful life events, psychopathy, and psychopathology in females and males. Future studies investigating the impact of stressful life events on psychopathology should include psychopathic traits and stress-reactivity.
