Attention-affect interactions and triarchic psychopathy: New electrophysiological insights from the late positive potential

One of the most prominent characteristics of psychopathy is a reduced processing of emotionally relevant information. However, it is still unclear how attentional mechanisms may modulate this deficit. The current study aimed to examine the impact of attentional focus on emotion processing in relation to the triarchic constructs of boldness, meanness, and disinhibition. Participants performed two tasks in which pleasant, neutral, and unpleasant framed pictures were presented. In the first task, participants were required to indicate the color of the frame (alternative-focus task), whereas in the second task they were instructed to indicate the emotional category of the image (affect-focus task). The Late Positive Potential (LPP) was used as an index of sustained engagement of attention to affective material. Confirming a successful task manipulation, we observed reduced LPP amplitudes, particularly for affective relevant material, in the alternative-focus task compared to the affect-focus task. Most interestingly, our results evidenced that trait meanness scores were associated with blunted elaborative processing of affective material (both appetitive and aversive) when this information was task-relevant (affect-focus task), but not when it was task-irrelevant (alternative-focus task). These findings indicate that high mean individuals are characterized by blunted elaborative processing of affective stimuli when their motivational relevance is determined in a top-down manner (i.e., when it is task-relevant). Our results highlight the need for further studying of the bottom-up and top-down dynamics of emotional attention in psychopathy.

Pain processing and antisocial behavior: A multimodal investigation of the roles of boldness and meanness

Antisocial behavior has been linked to an increased tolerance of painful stimuli; however, there is evidence that pain behavior is multidetermined. The current study used pain measures from 3 different modalities (pain tolerance, pain ratings, electrocortical reactivity) and assessed triarchic traits of boldness and meanness to clarify the dispositional basis of associations between pain processing and antisocial behavior. High boldness was significantly associated with blunted early neural response to painful and nonpainful stimuli as well as increased pain tolerance. High meanness was associated with blunted elaborative processing of painful images, lower ratings of perceived pain for self and others, and increased pain tolerance. Meanness also accounted for variance shared between pain processing and antisocial behavior. Findings demonstrate that boldness and meanness contribute to pain processing in different ways and suggest that meanness may uniquely account for the association between blunted pain processing and antisocial behavior.

The Good, the Bad, and the Ugly? A Triarchic Perspective on Psychopathy at Work

Does psychopathy have an upside in vocational contexts? Applying the triarchic model of psychopathy, we propose that the dimensions of boldness, disinhibition, and meanness have different relations to workplace outcomes. Focusing on boldness and in line with socioanalytic personality theory, we propose that political skill moderates the relation between boldness and job performance. Using a sample of 477 target-coworker pairings, we found interaction effects of boldness and political skill on contextual and task performance, and the buffering of counterproductive work behavior. Furthermore, political skill moderated the relation between boldness and adaptive performance. Disinhibition and meanness were positively correlated with counterproductive work behaviors, thereby reflecting the dark core of psychopathy. In sum, boldness is a trait linked to career success in the absence of the other traits that make up psychopathy as a whole. Furthermore, we encourage the use of the triarchic model as an overarching framework in vocational contexts.

Evaluating the validity of brief prototype-based informant ratings of triarchic psychopathy traits in prisoners

The validity of self-report psychopathy assessment has been questioned, especially in forensic settings where clinical evaluations influence critical decision-making (e.g., institutional placement, parole eligibility). Informant-based assessment offers a potentially valuable supplement to self-report but is challenging to acquire in under-resourced forensic contexts. The current study evaluated, within an incarcerated sample (n = 322), the extent to which brief prototype-based informant ratings of psychopathic traits as described by the triarchic model (boldness, meanness, disinhibition; Patrick et al., 2009) converge with self-report trait scores and show incremental validity in predicting criterion measures. Self/informant convergence was robust for traits of boldness and disinhibition, but weaker for meanness. Informant-rated traits showed incremental predictive validity over self-report traits, both within and across assessment domains. These findings indicate that simple prototype-based informant ratings of the triarchic traits can provide a useful supplement to self-report in assessing psychopathy within forensic-clinical settings.

Psychopathic Traits, Pubertal Timing, & Mental Health Functioning in Justice-Involved Adolescents

Although psychopathic traits and pubertal timing have garnered a great deal of attention as potent risk factors for antisocial trajectories, very little research has examined how these processes may be related. We investigated whether psychopathic traits were related to deviations in pubertal onset in a clinically-relevant sample of youth detained in juvenile detention facilities. One-hundred and thirty-seven adolescents (ages 12-17) completed surveys of pubertal timing, psychopathic traits, and mental health functioning. As predicted, psychopathic traits were found to be associated with pubertal timing, and the psychopathy facets evidenced differential associations with the onset of puberty. Trait disinhibition was associated with relatively earlier pubertal timing, whereas trait boldness appeared to confer protection against early pubertal onset in this sample. Symptoms of alcohol/ substance use and anger/ irritability were positively related to psychopathic traits, but only among youth who reported average-/late-pubertal development. These findings implicate psychopathic personality traits as individual difference variables that may influence the onset of pubertal timing and interact with pubertal timing to place justice-involved youth at risk for poor mental health.

Genetic and environmental influences on disinhibition, boldness, and meanness as assessed by the triarchic psychopathy measure in 19-20-year-old twins

BACKGROUND

The Triarchic Psychopathy Measure (TriPM) provides Disinhibition, Boldness, and Meanness scales for assessing the three trait domains of the triarchic model. Here we examined the genetic and environmental etiology of these three domains, including evaluation of potential sex differences.

METHODS

A total of 1016 men and women ages 19-20 years were drawn from the University of Southern California Risk Factors for Antisocial Behavior twin study.

RESULTS

Scores for the three TriPM scales were correlated to differing degrees, with the strongest phenotypic correlation between Disinhibition and Meanness. No sex differences were found in the genetic and environmental influences underlying these three domains, suggesting that the same genes and life experiences contribute to these traits in young men and women. For TriPM Disinhibition and Boldness, genetic factors explained about half or less of the variance, with the rest of the variance being explained by non-shared environmental factors. For TriPM Meanness, on the other hand, genetic, shared environmental, and non-shared environmental factors accounted for the variance. The phenotypic correlation between Disinhibition and Meanness was explained in part by common genes (26%), with the remainder attributable about equally to common shared (39%), and non-shared environmental influences (35%).

CONCLUSIONS

These findings contribute to our understanding of psychopathic personality traits by demonstrating the importance of heritable factors for disinhibition and boldness facets of psychopathy, and the importance of shared environmental influences for the meanness facet.

Psychopathic traits are associated with cortical and subcortical volume alterations in healthy individuals

Research suggests psychopathy is associated with structural brain alterations that may contribute to the affective and interpersonal deficits frequently observed in individuals with high psychopathic traits. However, the regional alterations related to different components of psychopathy are still unclear. We used voxel-based morphometry to characterize the structural correlates of psychopathy in a sample of 35 healthy adults assessed with the Triarchic Psychopathy Measure. Furthermore, we examined the regional grey matter alterations associated with the components described by the triarchic model. Our results showed that, after accounting for variation in total intracranial volume, age and IQ, overall psychopathy was negatively associated with grey matter volume in the left putamen and amygdala. Additional regression analysis with anatomical regions of interests revealed total triPM score was also associated with increased lateral orbitofrontal cortex (OFC) and caudate volume. Boldness was positively associated with volume in the right insula. Meanness was positively associated with lateral OFC and striatum volume, and negatively associated with amygdala volume. Finally, disinhibition was negatively associated with amygdala volume. Results highlight the contribution of both subcortical and cortical brain alterations for subclinical psychopathy and are discussed in light of prior research and theoretical accounts about the neurobiological bases of psychopathic traits.
