Altering the Cognitive-Affective Dysfunctions of Psychopathic and Externalizing Offender Subtypes with Cognitive Remediation

The Structure of Hypersexuality and Its Relation to Impulsivity

Among the multiple controversies surrounding hypersexuality is the important issue of whether it constitutes a univocal construct. Although an initial study supported its homogeneity, more resent research has identified two separate subcomponents-problematic sexuality and sexual drive. The present survey study addressed this issue in a sample that included both in-person tested college students (n = 69) and online respondents (n = 339). A factor analysis of scales attempting to capture the indicators of each subcomponent of hypersexuality yielded two correlated, but separate factors. Whereas Problematic Sexuality (PS) comprised scales measuring sexual compulsivity, using sex as a coping mechanism, and the negative consequences of sexual behavior, Sexual Drive (SD) was defined by frequent sexual activity, preoccupation with sexual fantasies, a predilection for impersonal sexual behavior, and facile sexual arousal. These two subcomponents of hypersexuality were found to covary with different types of impulsivity, further supporting their discrimination and providing external validation for their differentiation. Contrary to a priori hypotheses, however, PS correlated highly with Callous/Manipulative/Risk-Taking as well as with a predicted Affective Instability/Behavioral Disinhibition factor, suggesting that PS may constitute an equifinality of separate developmental trajectories for those high on both subtypes of hypersexuality.

Proposed Specifiers for Conduct Disorder (PSCD) scale: A Latent Profile Analysis with At-Risk Adolescents

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin in Pers Disord: Theory Res Treat 7:180-191, 2016) scale was designed to assess interrelated psychopathic trait domains in conjunction with symptoms of Conduct Disorder (CD) in children and adolescents (i.e., grandiose-manipulative, callous-unemotional, daring-impulsive). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985-992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9% White, 20.1% Black, 3.6% Hispanic, and 5.4% other) of adolescents (modal age = 17) in a military style residential facility (N = 409; Males = 80.6%). As hypothesized, a four-class solution was best, consistent with adult psychopathy subtyping research (Hare et al. in Handbook of Psychopathy 39-79, 2018; Roy et al. in Pers Disord: Theory Res Treat, in press). The PSCD subtype profiles were uniform across sex and race/ethnicity. Adolescents evincing a psychopathic trait propensity profile (elevated on all four PSCD domains) displayed the greatest number of arrests and higher overall externalizing psychopathology, compared to the other three latent classes, as well as higher internalizing psychopathology compared to adolescents with general delinquency. The PSCD provides a sound measure of psychopathic trait propensities in youth and our results offer investigators and clinicians a means for understanding person-centered psychopathic traits versus antisocial profiles among at-risk adolescents. Taken together, the current results may offer a viable approach for examining specific treatment targets based on PSCD subtype profiles.

Social exclusion evokes different psychophysiological responses in individuals high on the psychopathy facets fearless dominance and self-centered impulsivity

Individuals with psychopathic personality traits are generally thought to have difficulties in processing and experiencing emotions. These difficulties could also translate to emotionally charged social situations such as social exclusion. Being socially excluded is often experienced as stressful and unpleasant, potentially even leading to selfish or aggressive behavior-both of which are linked to certain aspects of psychopathy. The current study investigated self-report and physiological responses to social exclusion in the cyberball paradigm in a carefully selected community sample of individuals either scoring high on primary (N = 24) or secondary psychopathy traits (N = 17). Across the sample, the cyberball paradigm decreased experiences of joy and approach motivation, increased subjective anger reports, and induced changes in heart rate. In contrast, individuals scoring high on secondary psychopathy traits (Self-Centered Impulsivity group) displayed stronger physiological reactivity during a habituation phase of prolonged social exclusion than individuals scoring high on primary psychopathy traits (Fearless Dominance group), indexed by changes in skin conductance level. Moreover, a potential mismatch between self-reported and physiological arousal seemed to be only observable in individuals with high secondary psychopathy traits. Overall, the current results suggest diverging patterns of emotional processing and regulation in a social exclusion situation when comparing well-functioning individuals with varying psychopathy traits. It seemed as if individuals high on primary psychopathy traits were insensitive to contextual social cues, while individuals high on secondary psychopathy traits were more affected by the potentially threatening social situation. Cautiously transferring the current findings to forensic samples, they support the idea of moving from a behavioral understanding of the psychopathy construct to a more clinical picture with distinct cognitive and emotional processing patterns in individuals high on either primary or secondary psychopathy traits.

Triarchic psychopathy and affective picture processing: An event-related potential study

Psychopathy and its precursors appear to be associated with abnormal affective response. For example, individuals high in psychopathy show reduced psychophysiological response to unpleasant stimuli, which might explain low levels of empathy in psychopathic individuals, and their pursuit of individual goals without regard for others' wellbeing. In keeping with the notion that psychopathology is best represented on a continuum, the triarchic model suggests that psychopathy is characterized by elevations on three traits: boldness, meanness and disinhibition. Understanding how these traits relate to psychophysiological response to emotional stimuli would help validate the triarchic model, while also bridging to other psychopathological spectra (e.g., internalizing psychopathology, which is characterized by low boldness). Here, N = 123 young adults passively viewed unpleasant, pleasant and neutral pictures while subjective and electrocortical response were recorded. Controlling for the other triarchic traits, individuals with higher self-reported meanness had smaller late positive potentials (LPPs) to both pleasant and unpleasant pictures, whereas individuals higher in boldness had larger LPPs to unpleasant pictures. In addition, those higher in meanness rated unpleasant pictures as more pleasant and less emotionally arousing. Disinhibition was not associated with the LPP or ratings. Meanness appears to drive blunted response to unpleasant pictures that has previously been observed among those high on psychopathy, and may also be associated with reduced engagement with generic pleasant stimuli. Moreover, results converge with prior work on other traits of transdiagnostic relevance (e.g., extraversion), as well as internalizing symptoms, providing a bridge between psychopathy and other forms of psychopathology.

Impaired salience network switching in psychopathy

Growing evidence suggests that psychopathy is related to altered connectivity within and between three large-scale brain networks that support core cognitive functions, including allocation of attention. In healthy individuals, default mode network (DMN) is involved in internally-focused attention and cognition such as self-reference. Frontoparietal network (FPN) is anticorrelated with DMN and is involved in externally-focused attention to cognitively demanding tasks. A third network, salience network (SN), is involved in detecting salient cues and, crucially, appears to play a role in switching between the two anticorrelated networks, DMN and FPN, to efficiently allocate attentional resources. Psychopathy has been related to reduced anticorrelation between DMN and FPN, suggesting SN's role in switching between these two networks may be diminished in the disorder. To test this hypothesis, we used independent component analysis to derive DMN, FPN, and SN activity in resting-state fMRI data in a sample of incarcerated men (N = 148). We entered the activity of the three networks into dynamic causal modeling to test SN's switching role. The previously established switching effect of SN among young, healthy adults was replicated in a group of low psychopathy participants (posterior model probability = 0.38). As predicted, SN's switching role was significantly diminished in high psychopathy participants (t(145) = 26.39, p < .001). These findings corroborate a novel theory of brain function in psychopathy. Future studies may use this model to test whether disrupted SN switching is related to high psychopathy individuals' abnormal allocation of attention.

Aggressive and psychopathic traits are linked to the acquisition of stable but imprecise hostile expectations

Individuals with hostile expectations (HEX) anticipate harm from seemingly neutral or ambiguous stimuli. However, it is unclear how HEX are acquired, and whether specific components of HEX learning can predict antisocial thought, conduct, and personality. In an online sample of healthy young individuals (n = 256, 69% women), we administered a virtual shooting task and applied computational modelling of behaviour to investigate HEX learning and its constellation of correlates. HEX acquisition was best explained by a hierarchical reinforcement learning mechanism. Crucially, we found that individuals with relatively higher self-reported aggressiveness and psychopathy developed stronger and less accurate hostile beliefs as well as larger prediction errors. Moreover, aggressive and psychopathic traits were associated with more temporally stable hostility representations. Our study thus shows that aggressiveness and psychopathy are linked with the acquisition of robust yet imprecise hostile beliefs through reinforcement learning.

Psychopathy in Correctional Settings: Considerations for Developing and Implementing a Treatment Program

Psychopathy is associated with higher levels of violence as well as general and violent recidivism after release from prison. A disorder with a long and rich clinical and research history, psychopathy has gained an undeserved reputation as a syndrome that is unresponsive to treatment. This article presents information that undermines long-standing problematic assumptions regarding the treatability of individuals with psychopathic traits and posits that implementing treatment programs in correctional settings is critical to decrease recidivism and violence. We discuss several treatment programs that have evidenced some success in the treatment of individuals with psychopathy and have the potential to be widely implemented in correctional settings, as well as general tenets of successful treatment programs and specific targets.

Development of a cortical delay discounting assay: a potential biomarker of externalizing disorders

BACKGROUND

People who tend to impulsively choose smaller, sooner rewards over larger, later rewards are at increased risk for addiction and psychiatric disorders. A neurobiological measure of the tendency to overvalue immediate gratification could facilitate the study of individuals who are susceptible to these mental disorders. The objective of this research was to develop a cortical assay of impulsive choice for immediate rewards.

METHODS

A cortex-based assay of impulsive choice was developed using 1105 healthy adults from the Human Connectome Project, and then cross-validated in two independent samples of adults with elevated rates of psychiatric disorders.

RESULTS

Study 1: Cortical delay discounting (C-DD) was developed using a multivariate additive model of gray matter thickness across both hemispheres. Higher C-DD corresponded to thinner cortex and greater impulsive choice for immediate rewards. It also predicted cannabis use beyond established risk factors for drug use, including familial substance use, childhood conduct problems, personality traits, and cognitive functioning. Study 2: C-DD replicated the association with delay discounting performance from study 1. Structural equation modeling showed C-DD covaried with symptoms of externalizing, but not internalizing disorders. Study 3: C-DD positively predicted future delay discounting behavior (6-34 months later).

CONCLUSIONS

Across three studies, a cortical assay of impulsive choice evidenced consistent associations with drug use and delay discounting task performance. It was also uniquely associated with psychiatric disorders that share impulsivity as a core feature. Together, findings support the utility of C-DD as a neurobiological assay of impulsive decision-making and a possible biomarker of externalizing disorders.

Pathways to antisocial behavior: a framework to improve diagnostics and tailor therapeutic interventions

The Antisocial Personality Disorder (ASPD), and antisocial behavior (ASB) in general, is associated with significant impact on individuals themselves, their environment, and society. Although various interventions show promising results, no evidence-based treatments are available for individuals with ASPD. Therefore, making informed choices about which treatment can be applied to an individual patient is complicated. Furthermore, contradictory findings on therapy effectiveness and underlying factors of ASB, such as cognitive impairments and personality traits, fuel the debate whether the conceptualization of ASPD in the DSM-5 is accurate and whether this population can be seen as homogeneous. A conceptual framework, based on the reciprocal altruism theory, is presented in which we propose different pathways to ASB. These pathways suggest underlying dynamics of ASB and provide an explanation for previous contradictory research outcomes. This framework is intended to serve as a clinically relevant model that provides directions for improving diagnostics and matching treatments to underlying dynamics in the antisocial population.

Psychopathy subdomains in violent offenders with and without a psychotic disorder

BACKGROUND

Violence in psychosis has been linked to antisocial behavior and psychopathy traits. Psychopathy comprises aspects of interpersonal, affective, lifestyle, and antisocial traits which may be differently involved in violent offending by persons with psychotic disorders. We explored psychopathy subdomains among violent offenders with and without a psychotic disorder.

METHODS

46 males, with a history of severe violence, with (n = 26; age 35.85 ± 10.34 years) or without (n = 20; age 39.10 ± 11.63 years) a diagnosis of a psychotic disorder, were assessed with the Psychopathy Checklist-Revised (PCL-R). PCL-R was split into subdomains following the four-facet model. Group differences in total and subdomain scores were analyzed with a general linear model with covariates.

RESULTS

Total PCL-R scores did not differ between the groups (p = 0.61, Cohen's d = 0.17). The violent offenders without psychotic disorders had higher facet 2 scores than the patient group with psychotic disorders (p = 0.029, Cohen's d = 0.77). Facet 1, 3, or 4 scores did not differ between the groups. Controlling for age did not alter the results.

CONCLUSION

Patients with a psychotic disorder and a history of severe violence have lower affective psychopathy scores than violent offenders without psychotic disorders. This observation may point toward distinct underlying mechanisms for violence and may provide a target for focused treatment and prevention.

Associations Between Psychopathic Traits and Laboratory-Based Aggression: Moderating Effects of Provocation and Distraction

There are two distinct combinations of psychopathic traits (primary and secondary) that have been proposed to be a function of unique cognitive-affective deficits. This study sought to use theories of psychopathy to understand the factors that exacerbate (i.e., provocation) and attenuate (i.e., distraction) aggression in individuals high in psychopathic traits in a controlled laboratory task. Male undergraduates, who scored across the range of primary and secondary psychopathic traits, completed the Taylor Aggression Paradigm (TAP; Taylor, 1967) under conditions of low and high provocation. Participants were also randomly assigned to either a distraction condition, in which they completed a distracting concurrent task, or a control condition, in which no such task was completed. Inconsistent with our prediction, results showed that regardless of condition, primary psychopathic traits were positively related to laboratory aggression. Consistent with our hypothesis, a positive association between secondary psychopathic traits and laboratory physical aggression was observed following high provocation among nondistracted participants; this association was significantly reduced among distracted participants. These results clarify the factors that contribute to aggression for individuals high in psychopathic traits and may provide directions for future intervention development.

Are Children High on Callous-Unemotional Traits Emotionally Blind? Testing Eye-Gaze Differences

Callous-unemotional traits have been associated with difficulties in identifying and responding to others' emotions. To inform this line of research, the current study investigated the eye gaze behavior of children (n = 59; mean-age = 6.35) with varying levels of callous-unemotional (CU) traits with the use of eye-tracker methodology, as well as their ability to accurately identify emotional expressions. Participating children were selected from a large screening sample (N = 1283). Main findings supported a reduced fixation rate to the eye-region and an increased fixation in the mouth area of emotional faces among children high on callous-unemotional traits (HCU), irrespective of emotion expressed (i.e., fear, sad, angry and happy) and age of individuals portrayed in images (adult versus child faces). Further, findings suggested that HCU children were less likely to accurately identify facial emotional expressions, which might be due to the identified attentional neglect to the eye region of emotional faces. Current findings support the importance of early prevention and intervention programs that can enhance the emotional development and social adjustment of HCU children.

The importance of an exaggerated attention bottleneck for understanding psychopathy

The psychopath has long captured the imagination. A name such as Ted Bundy evokes a morbid curiosity. The crimes committed by Bundy are so cruel that it is hard to imagine how someone could do such things. In this review we discuss evidence that exaggeration in an attention bottleneck is one mechanism that makes it possible for psychopathic individuals to be adept at focusing on a single stimulus feature or goal but struggle to process multiple streams of information simultaneously. This exaggeration may partly explain the behavioral, affective, and social deficits that are apparent among psychopathic individuals. Further research on this attentional mechanism may promote a science that adequately captures the complexity of psychopathic behavior and offers new avenues for intervention.

Examination of the importance of anger/irritability and limited prosocial emotion/callous-unemotional traits to understand externalizing symptoms and adjustment problems in adolescence: A 10-year longitudinal study

Objective

Within a longitudinal study (10-year follow-up), we aim to examine the role of anger/irritability and limited prosocial emotion/callous-unemotional traits in predicting externalizing symptoms and adjustment problems in individuals formerly in youth residential care institutions.

Method

These dimensions were assessed in 203 young adults, with baseline assessments during youth residential care and a follow-up 10 years later.

Results

In general, emotional problems and psychopathological symptoms did not reduce over time. Analyses of regression revealed that a younger age at baseline, anger/irritability both at baseline assessment, and regarding their aggravation over time refer to significant predictors of the level of externalizing symptoms at 10-year follow-up (R ² = 0.431) and the worsening of externalizing symptoms over time (R ² = 0.638). Anger/irritability has been observed to be a significant predictors of both the level of adjustment problems at 10-year follow-up (R ² = 0.471) and its worsening over time (R ² = 0.656).

Discussion

Our results suggest that dysregulation of anger/irritability is a key factor in the prediction of long-term externalizing symptoms and adjustment problems as well as its worsening over time. Possible implications for intervention and prevention are discussed.

The role of self-regulatory control processes in understanding aggressive ideations and behaviors: An experience sampling method study

INTRODUCTION

In this study, we aimed to examine the association between aggressive ideations and aggressive behaviors in everyday life, as well as the role of processes related to self-regulatory control (i.e., self-control, ego depletion, and emotional states), using experience sampling methods (ESM).

METHODS

A total of 62 male adolescents performed a baseline measure of aggression, violent ideations (trait level), and ESM assessments, including four measures per day during nine consecutive days.

RESULTS

At a state level, aggressive ideations were associated with higher negative emotions during the previous day as well as with lower self-control and stronger anger rumination at the moment. Aggressive behaviors were related to higher anger rumination at the moment and to the manifestation of higher intensity of aggressive ideations derived in the previous measure. Higher self-control was related to a lower probability of aggressive behavior.

DISCUSSION

This study highlights the temporal link between aggressive ideations and behaviors in everyday life as well as the role of self-control in understanding aggressivity in the lap of time. Furthermore, we observed that expressions of anger (i.e., reactivity, as well as rumination) were central in the understanding of aggressive ideations and behaviors in the everyday life (i.e., at within-person variability at the state level).

Machine learning approaches for parsing comorbidity/heterogeneity in antisociality and substance use disorders: A primer

By some accounts, as many as 93% of individuals diagnosed with antisocial personality disorder (ASPD) or psychopathy also meet criteria for some form of substance use disorder (SUD). This high level of comorbidity, combined with an overlapping biopsychosocial profile, and potentially interacting features, has made it difficult to delineate the shared/unique characteristics of each disorder. Moreover, while rarely acknowledged, both SUD and antisociality exist as highly heterogeneous disorders in need of more targeted parcellation. While emerging data-driven nosology for psychiatric disorders (e.g., Research Domain Criteria (RDoC), Hierarchical Taxonomy of Psychopathology (HiTOP)) offers the opportunity for a more systematic delineation of the externalizing spectrum, the interrogation of large, complex neuroimaging-based datasets may require data-driven approaches that are not yet widely employed in psychiatric neuroscience. With this in mind, the proposed article sets out to provide an introduction into machine learning methods for neuroimaging that can help parse comorbid, heterogeneous externalizing samples. The modest machine learning work conducted to date within the externalizing domain demonstrates the potential utility of the approach but remains highly nascent. Within the paper, we make suggestions for how future work can make use of machine learning methods, in combination with emerging psychiatric nosology systems, to further diagnostic and etiological understandings of the externalizing spectrum. Finally, we briefly consider some challenges that will need to be overcome to encourage further progress in the field.

Non-Pharmaceutical Interventions for Self-Regulatory Failures in Adolescents Suffering from Externalizing Symptoms: A Scoping Review

Introduction: Deficits of self-regulation (SR) are a hallmark of externalizing (EXT: offending or aggressive behaviors) symptoms in adolescence. Objectives: This scoping review aims (1) to map non-pharmaceutical interventions targeting SR processes to reduce EXT symptoms in adolescents and (2) to identify research gaps, both of which will provide recommendations for future studies. Methods: Systematic searches were carried out in eight bibliographic databases up to March 2021, combining the following concepts: self-regulation, externalizing symptoms, adolescents, and non-pharmaceutical interventions. Results: We identified 239 studies, including 24,180 youths, mainly from North America, which described a plethora of non-pharmaceutical interventions targeting SR to alleviate EXT symptoms in adolescents (10–18 years of age). The majority of studies (about 70%, k = 162) represent samples with interventions exposed to “selective” or “indicated” prevention. Curriculum-based (i.e., multiple approaches targeting several domains such as emotion, cognition, and social) interventions (31.4%) were the most common type of intervention. Moreover, studies on cognitive-based interventions, mind-based interventions, and emotional-based interventions have increased over the last decades. Network analyses allowed us to identify several hubs between curriculum-based interventions, cognitive SR processes, as well as aggressiveness, conduct problems, and irritability/anger dysregulation. In addition, we identified gaps of studies concerning the physiological SR processes and on some types of interventions (i.e., body-based interventions and externally mediated interventions) or, more specifically, on promising tools, such as biofeedback, neurofeedback, as well as programs targeting neuropsychological processes (e.g., cognitive remediation). Conclusions: This scoping review stresses the plethora of interventions, identified hubs, and emerging fields, as well as some gaps in the literature, which together may orient future studies.

Neurocognitive abilities associated with antisocial behavior with and without callous-unemotional traits in a community sample

OBJECTIVE

Antisocial behavior (aggression, rule breaking) is associated with lower intelligence and executive function deficits. Research has not clarified whether these associations differ with the presence of callous-unemotional (CU) traits, particularly within levels of antisocial behavior observed in the community.

METHOD

We examined whether antisocial behavior and CU traits were differentially associated with intelligence and executive function metrics in 474 adolescent twins (Mean age = 14.18; SD = 2.20) sampled from birth records to represent youth in the community living in neighborhoods with above average levels of poverty. Intelligence was assessed using standardized scores from the Shipley-2. Executive function was assessed using Go/No-Go and Stop Signal tasks.

RESULTS

Neither antisocial behavior, nor CU traits alone, were associated with cognitive functioning when accounting for demographic factors. However, antisocial behavior and CU traits interacted to predict reaction time variability. At low levels of CU traits, antisocial behavior was associated with higher reaction time variability (traditionally thought to reflect worse sustained attention). At high levels of CU traits, antisocial behavior was associated with lower reaction time variability (thought to reflect better sustained attention).

CONCLUSION

Elevated antisocial behavior and CU traits may be characterized by a distinct neurocognitive profile compared to elevated antisocial behavior in isolation. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Psychopathy

Psychopathy is a personality disorder characterized by a constellation of affective, interpersonal, lifestyle and antisocial features whose antecedents can be identified in a subgroup of young people showing severe antisocial behaviour. The prevalence of psychopathy in the general population is thought to be ~1%, but is up to 25% in prisoners. The aetiology of psychopathy is complex, with contributions of both genetic and environmental risk factors, and gene-environment interactions and correlations. Psychopathy is characterized by structural and functional brain abnormalities in cortical (such as the prefrontal and insular cortices) and subcortical (for example, the amygdala and striatum) regions leading to neurocognitive disruption in emotional responsiveness, reinforcement-based decision-making and attention. Although no effective treatment exists for adults with psychopathy, preliminary intervention studies targeting key neurocognitive disturbances have shown promising results. Given that psychopathy is often comorbid with other psychiatric disorders and increases the risk of physical health problems, educational and employment failure, accidents and criminality, the identification of children and young people at risk for this personality disorder and preventative work are important. Indeed, interventions that target the antecedents of psychopathic features in children and adolescents have been found to be effective.

The Structure, Covariates, and Etiology of Hypersexuality: Implications for Sexual Offending

PURPOSE OF REVIEW

A substantial increase in research on the structure, covariates, and etiology of hypersexuality has emerged during the last decade. It is the goal of this review to summarize and integrate this research and to indicate some practical implications for clinical and forensic practice, especially as applied to those who have sexually offended.

RECENT FINDINGS

Studies from the last half-decade converge on the conclusion that hypersexuality has both problematic and high sexual drive components. Both aspects have consistently been found to be distributed dimensionally and not categorically. Each subdimension covaries differentially with specific types of impulsivity. In addition to sexual abuse, psychological or emotional abuse has emerged to be a potent developmental antecedent of hypersexuality. Current research has focused on the problematic dimension of hypersexuality and has neglected to specify the criteria for high sexual drive. Lacking are large-scale representative and clinical samples that provide determination of optimal cutoffs for treatment and dispositional decisions for both dimensions of hypersexuality. Research on the etiology of both aspects of hypersexuality is in its infancy, and more differentiated assessments of developmental abuse histories are required.

Psychopathic traits, inhibition, and positive and negative emotion: Results from an emotional Go/No-Go task

Difficulty stopping unwanted or inappropriate actions (i.e., inhibitory control) is implicated in antisocial behaviors, which are common in people high in psychopathic traits. Recent research indicates that, for those with antisocial personality, inhibitory control is impaired under negative emotional contexts; however, it is unclear whether this impairment extends to persons with psychopathic traits and to impairments under positive emotional contexts. Identifying some of these distinctions can point to therapeutics that target negative emotion specifically or emotion dysregulation broadly. We sought to identify unique relationships between distinct facets of psychopathy and inhibitory control in the context of positive, negative, and neutral stimuli. Using a community sample (N = 117), event-related potentials were recorded during an emotional-linguistic Go/No-Go task. Results indicated distinct cognition-emotion relationships for each psychopathy facet. Higher interpersonal facet scores related to reciprocal interference between cognition and emotion. Higher callous affect facet scores related to reduced inhibitory and emotional processing, except when stimuli were most engaging (emotional No-Go trials). Higher erratic lifestyle facet scores related to increased effort required to process both emotion and inhibition cues. Finally, higher antisocial facet scores related to poorer behavioral inhibition overall. This research challenges the theoretical accounts of psychopathy focused on specific deficits in negative emotion, such as fearlessness, while offering some support for theories related to attentional dysfunction. Results also highlight the importance of facet-level theorizing, as results varied by facet. This study may inform efforts to reduce disinhibited behaviors, particularly in emotional contexts, among those high in certain psychopathic traits.

Effects of Psychopathy on Neurocognitive Domains of Impulsivity in Abstinent Opiate and Stimulant Users

Background: Psychopathy and substance use disorders (SUDs) are both characterized by neurocognitive impairments reflecting higher levels of impulsivity such as reward-driven decision-making and deficient inhibitory control. Previous studies suggest that psychopathy may exacerbate decision-making deficits, but it may be unrelated to other neurocognitive impairments among substance dependent individuals (SDIs). The aim of the present study was to examine the role of psychopathy and its interpersonal-affective and impulsive-antisocial dimensions in moderating the relationships between dependence on different classes of drugs and neurocognitive domains of impulsivity. Method: We tested 693 participants (112 heroin mono-dependent individuals, 71 heroin polysubstance dependent individuals, 115 amphetamine mono-dependent individuals, 76 amphetamine polysubstance dependent individuals, and 319 non-substance dependent control individuals). Participants were administered the Psychopathy Checklist: Screening Version (PCL:SV) and seven neurocognitive tasks measuring impulsive choice/decision-making (Iowa Gambling Task; Cambridge Gambling Task; Kirby Delay Discounting Task; Balloon Analog Risk Task), and impulsive action/response inhibition (Go/No-Go Task, Immediate Memory Task, and Stop Signal Task). Results: A series of hierarchical multiple regressions revealed that the interpersonal-affective dimension of psychopathy moderated the association between decision-making, response inhibition and both amphetamine and heroin dependence, albeit differently. For amphetamine users, low levels of interpersonal-affective traits predicted poor decision-making on the Iowa Gambling Task and better response inhibition on the Stop Signal task. In contrast, in heroin users high interpersonal-affective psychopathy traits predicted lower risk taking on the Cambridge Gambling Task and better response inhibition on the Go/No-Go task. The impulsive-antisocial dimension of psychopathy predicted poor response inhibition in both amphetamine and heroin users. Conclusions: Our findings reveal that psychopathy and its dimensions had both common and unique effects on neurocognitive function in heroin and amphetamine dependent individuals. Our results suggest that the specific interactions between psychopathy dimensions and dependence on different classes of drugs may lead to either deficient or superior decision-making and response inhibition performance in SDIs, suggesting that psychopathy may paradoxically play a protective role for some neurocognitive functions in specific subtypes of substance users.

Impairment of Both Reward and Punishment Learning in Males Who Have Sexually Offended Against a Child

Prior studies suggest that persons with a sexual offense against a child (PSOCs) present with an impairment in learning from reinforcement, which may contribute to the behavioral dysregulation often seen in PSOCs. Therefore, gaining more insight into the nature of this impairment seems essential to better understand child sexual (re)offending. Using a passive avoidance task, we found that PSOCs (n = 57) have difficulties with selecting behaviors that are associated with reward and suppressing behaviors that are associated with punishment relative to nonoffending men (n = 33), but not compared with persons with a nonsexual offense history (n = 31). The latter ability was particularly compromised in nonpedophilic PSOCs. By unraveling a source of pathology in the mechanisms that are involved in behavioral control, this study helps setting a step toward new, more tailored, therapeutic approaches.

Connections that characterize callousness: Affective features of psychopathy are associated with personalized patterns of resting-state network connectivity

•

There was significant heterogeneity in participants’ neural networks.

•

Psychopathy associated with default mode-central executive network connectivity.

•

Associations were specific to affective psychopathic traits.

Background

Psychopathic traits are hypothesized to be associated with dysfunction across three resting-state networks: the default mode (DMN), salience (SN), and central executive (CEN). Past work has not considered heterogeneity in the neural networks of individuals who display psychopathic traits, which is likely critical in understanding the etiology of psychopathy and could underlie different symptom presentations. Thus, this study maps person-specific resting state networks and links connectivity patterns to features of psychopathy.

Methods

We examined resting-state functional connectivity among eight regions of interest in the DMN, SN, and CEN using a person-specific, sparse network mapping approach (Group Iterative Multiple Model Estimation) in a community sample of 22-year-old men from low-income, urban families (N = 123). Associations were examined between a dimensional measure of psychopathic traits and network density (i.e., number of connections within and between networks).

Results

There was significant heterogeneity in neural networks of participants, which were characterized by person-specific connections and no common connections across the sample. Psychopathic traits, particularly affective traits, were associated with connection density between the DMN and CEN, such that greater density was associated with elevated psychopathic traits.

Discussion

Findings emphasize that neural networks underlying psychopathy are highly individualized. However, individuals with high levels of psychopathic traits had increased density in connections between the DMN and CEN, networks that have been linked with self-referential thinking and executive functioning. Taken together, the results highlight the utility of person-specific approaches in modeling neural networks underlying psychopathic traits, which could ultimately inform personalized prevention and intervention strategies.

Suicide Ideation Among Male Prisoners: Preliminary Evidence That Psychopathic Traits are Indirectly Linked to Suicide Ideation Through Thwarted Interpersonal Needs

BACKGROUND

The relation between psychopathic traits and suicide ideation (SI) is frequently discussed but little research has examined potential mechanisms underlying this association. The interpersonal theory of suicide (ITS) proposes two mechanisms in the pathogenesis of suicidal desire: thwarted belongingness (TB) and perceived burdensomeness (PB). This study cross-sectionally tested TB and PB as possible explanatory links in the relation between psychopathic traits and SI.

METHOD

Archival data from 784 male U.K. prisoners (Mage  = 37.21, SD = 9.97) were analyzed using structural equation modeling.

RESULTS

Psychopathic traits were indirectly associated with SI through more specific suicide-promoting processes - namely TB and PB. More specifically, results indicated that Egocentricity and Stimulus Seeking were indirectly associated with SI through PB and TB in combination. However, results indicated specific indirect effects of TB in the relations between the Antisocial Behavior, Egocentricity, and Stimulus Seeking facets, and SI, whereas specific indirect effects for PB were only significant in the relations between Egocentricity and Stimulus Seeking facets and SI.

CONCLUSION

Preliminary results are consistent with the ITS and suggest that psychopathic traits may be distal risk markers for SI and provide direction for future research that could inform suicide prevention efforts among male prisoners high in such traits.

Promoting a Safe Environment in Our Cities: Towards a Theoretical Model of "Moral Deficit" for Appropriate Psychopathic Therapy

The increasing reported incidents of knife crime in cities and the release on parole of “rehabilitated” violent criminals are creating an unsafe urban environment. Such occurrences suggest that measures taken to address psychopathic-oriented behaviour may have been ineffective because the individual’s degree of “moral deficit” is not fully accounted for in the application of specific therapies. This study developed a theoretical model of “moral deficit” that is aligned with the appropriateness of therapy, ranging from the extreme “classical approach” of total confinement justified by a belief in the incurability of psychopaths to the modern therapy that aims to reintegrate the psychopath with society using “moralizing therapy”. Analysis of secondary data from extant literature was used to develop the theoretical model of “moral deficit”. Secondary data analysis suggests that the extent of psychopathic “moral deficit” may be an important factor in the selection of appropriate therapeutic measures for psychopathy treatment and the rehabilitation of psychopaths as law-abiding members of society. We conclude that a specific type of psychopathic moral deficit may have an important bearing on the appropriateness of treatment. It is recommended that the treatment of psychopathy makes greater provision for the extent and type of psychopathic “moral deficit” in assessing the most appropriate applications for the treatment of psychopathy and promoting the safety of urban environments.

Biocognitive Classification of Antisocial Individuals Without Explanatory Reductionism

Effective and specifically targeted social and therapeutic responses for antisocial personality disorders and psychopathy are scarce. Some authors maintain that this scarcity should be overcome by revising current syndrome-based classifications of these conditions and devising better biocognitive classifications of antisocial individuals. The inspiration for the latter classifications has been embedded in the Research Domain Criteria (RDoC) approach. RDoC-type approaches to psychiatric research aim at transforming diagnosis, provide valid measures of disorders, aid clinical practice, and improve health outcomes by integrating the data on the genetic, neural, cognitive, and affective systems underlying psychiatric conditions. In the first part of the article, we discuss the benefits of such approaches compared with the dominant syndrome-based approaches and review recent attempts at building biocognitive classifications of antisocial individuals. Other researchers, however, have objected that biocognitive approaches in psychiatry are committed to an untenable form of explanatory reductionism. Explanatory reductionism is the view that psychological disorders can be exclusively categorized and explained in terms of their biological causes. In the second part of the article, we argue that RDoC-like approaches need not be associated with explanatory reductionism. Moreover, we argue how this is the case for a specific biocognitive approach to classifying antisocial individuals.

'You can tell a victim by the tilt of her head as she walks': psychopathic personality and social-emotional processing

Much contention and speculation exists regarding the emotional and social skills associated with psychopathic personality, including the idea of a predatory perception. The current study examined the relationship between psychopathic personality and social and emotional processing. The study utilised a quasi-experimental design along with self-report measures to examine psychopathy in a community sample (N = 115) of males and females. To examine psychopathy and social information processing, a series of Mixed Design ANOVA's were conducted to examine the effect of psychopathy on character recall. Psychopathy was found to significantly predict recall of the unsuccessful character, however, did not predict recall of character gender or emotion. Two hierarchical regressions analyses were conducted to examine emotional intelligence and empathy. Psychopathy was found to be a significant negative predictor of empathy, however, did not significantly predict emotional intelligence. Implications for the current study lie within advancing the empirical understanding on psychopathic personality and victim vulnerability.

A Motivational Framework for Psychopathy: Toward a Reconceptualization of the Disorder

Abstract. The link between psychopathy and violence has been well documented. Estimates suggest psychopathic offenders are responsible for as much as 40% of violence-related crime, and that they show rates of violent recidivism up to five times higher than non-psychopathic offenders. Existing theories of the disorder argue that this violence stems from a core insensitivity to emotional/aversive information, or from a core inability to optimally allocate processing resources in complex environments. However, some newer findings have been difficult for existing theories to assimilate; moreover, successful treatment programs based off current conceptualizations have been slow to develop. With this in mind, the current paper proposes a new motivational framework for psychopathy, within which the disorder is conceptualized as stemming from more strategic, motivated processes. The paper begins by reviewing traditional theories of psychopathy and highlighting their explanatory strengths and limitations. The proposed motivational framework is then outlined, and a supportive rationale for the framework provided. Next, the paper undertakes a selective review of some of the most empirically supported features of the disorder, to highlight how these features may be productively reformulated within a motivational framework. Finally, the paper suggests several methods through which an empirical evaluation of the proposed ideas may be undertaken, and explores potential implications of a motivational framework for next-generation rehabilitation and treatment opportunities.

Impaired processing of threat in psychopathy: A systematic review and meta-analysis of factorial data in male offender populations

Background

Psychopathy is a personality disorder characterised by two underlying factors. Factor 1 (affective and interpersonal deficits) captures affective deficits, whilst Factor 2 (antisocial and impulsive/disorganised behaviours) captures life course persistent antisocial behaviours. Impaired processing of threat has been proposed as an aetiologically salient factor in the development of psychopathy, but the relationship of this impairment to the factorial structure of the disorder in adult male offenders is unclear.

Objectives

To investigate whether threat processing deficits are characteristic of psychopathy as a unitary construct or whether such deficits are specifically linked to higher scores on individual factors.

Data sources

A systematic review of the literature was conducted by searching PubMed, Web of Science and PsycINFO.

Methods

Studies were included if they (1) reported physiological measures of threat response as the primary outcome measure (2) indexed psychopathy using a well-validated clinician rated instrument such as the PCL-R (3) investigated male offenders between 18 and 60 years of age (4) reported threat processing analyses using both Factor 1 and Factor 2 scores (5) provided sufficient data to calculate effect sizes and (6) were published in English-language peer-reviewed journals. We identified twelve studies with data on 1112 participants for the meta-analysis of the relationship with Factor 1 scores, and nine studies with data on 801 participants for the meta-analysis of the relationship with Factor 2 scores. We conducted the meta-analyses to calculate correlations using random-effects models.

Results

PCL-R/SV Factor 1 scores were significantly and negatively related to threat processing indices (r = -0.22, (95%CI [-0.28, -.017]). Neither PCL-R/SV Factor 2 scores (r = -0.005, 95%CI [-0.10, 0.09]), nor PCL-R total score (r = -0.05, (95%CI [-0.15, -0.04]) were related to threat processing indices. No significant heterogeneity was detected for the Factor score results.

Conclusions

The meta-analyses of the distinct psychopathy factors suggest that the threat processing deficits observed in male offenders with psychopathy are significantly associated with higher scores on Factor 1. A similar relationship does not exist with Factor 2 scores. Our findings highlight the importance of investigating the potentially discrete relationships between aetiological variables and the two factor constructs in the disorder.

Childhood maltreatment experiences and problematic sexual outcomes in adult males who have sexually offended: Further evidence of the potency of male caregiver psychological abuse

BACKGROUND

Although research on the developmental antecedents of sexual offending has tended to focus on sexual abuse, recent research in juveniles and adults who have sexually offended suggests that psychological abuse perpetrated by a male caregiver may be a particularly important factor in the development of problematic sexual interests and behaviors.

OBJECTIVE

This study aimed to extend previous findings by investigating the association between psychological abuse by a male caregiver and problematic sexual outcomes in a sample of adult males who had sexually offended.

PARTICIPANTS

Participants were 529 adult males incarcerated for sexual offenses, 21% of whom were civilly committed.

METHODS

Childhood maltreatment and problematic sexual outcomes were assessed using the Multidimensional Assessment of Sex and Aggression, a contingency-based inventory that assesses domains related to sexual aggression. Hierarchical regressions were calculated examining the association between childhood abuse types and sexual outcomes.

RESULTS

Childhood sexual abuse was associated with child sexual (β = .247, p < .001) and other paraphilic interests (β = .189, p < .001). Male caregiver psychological abuse also emerged as marginally associated with child sexual interest (β = .100, p = .059), even after controlling for other abuse types.

CONCLUSIONS

These results partially replicate recent findings in a juvenile sample and challenge conventional developmental theories of sexual offending, by suggesting that male caregiver psychological abuse may play a role in the etiology of child sexual interest among males who have sexually offended. This study also suggests a possible gender symmetry effect moderating the developmental consequences of abuse.

A review of psychopathy and Cluster B personality traits and their neural correlates in female offenders

Although men commit more crime and are incarcerated at higher rates than women, women represent the fastest growing segment of the justice system. Empirical work suggests that psychopathy and Cluster B disorders are implicated in antisocial behavior across gender, and that neurobiological correlates of personality may inform such behavior. This review utilizes a gendered perspective to discuss psychopathy and Cluster B disorders in relation to antisocial behavior and incorporates work on neural correlates of personality disorders. Co-morbidity across these conditions may be partly explained by similar frontal deficits, reflective of disinhibition. Affective processing abnormalities appear to be characterized by distinct deficits in limbic/paralimbic regions, reflecting differential etiological underpinnings and behavioral outcomes. This review underscores the utility in examining personality pathology together with neurobiological and environmental factors. Methodological issues and clinical implications are also discussed.

Reinforcement learning in child molesters

BACKGROUND

Child molesters form a heterogeneous group, but one generally shared characteristic is maladaptive, rigid behaviour. Impairments in reinforcement learning may explain these maladaptive tendencies, but this has not been systematically investigated. Further, it is not known if such impairments vary with subtype of child molesters.

AIMS

To investigate the presence of impairments in reinforcement learning among child molesters and to test for differences in patterns of impairment with subtype.

METHODS

A group of 59 child molesters was recruited from several prisons in a two-stage screening process, the first using records and the second interview; a comparison group of 33 offenders who had never committed a sex offence and who denied paedophile ideation was similarly recruited; 36 nonoffender comparison men were recruited by social media and word of mouth. Each was asked to perform a probabilistic reversal learning task, in which stimulus-outcome contingencies had to be learned.

RESULTS

Child molesters, as a group, made significantly more errors on the probabilistic reversal learning task than the nonoffenders; the comparison offenders and the nonoffenders gained similar scores, although findings may have been confounded by older age in the child molester group. Nonpaedophilic child molesters had significantly worse scores than paedophilic child molesters.

CONCLUSIONS

Child molesters, especially those not diagnosed with paedophilia, have deficits during both the acquisition and reversal of contingencies, suggesting reinforcement learning deficits that may undermine their capacity to benefit maximally from therapy without preliminary work to repair those deficits, possibly in conjunction with extending the offender programmes. Testing before programme entry would enable accurate targeting of scarce resources in this respect.

Psychopathic traits are associated with reduced fixations to the eye region of fearful faces

Impairments in processing fearful faces have been documented in both children and adults with psychopathic traits, suggesting a potential mechanism by which psychopathic individuals develop callous and manipulative interpersonal and affective traits. Recently, research has demonstrated that psychopathic traits are associated with reduced fixations to the eye regions of faces in samples of children and community-dwelling adults, however this relationship has not yet been established in an offender sample with high levels of psychopathy. In the current study, we employed eye-tracking with paradigms involving the identification and passive viewing of facial expressions of emotion, respectively, in a sample of adult male criminal offenders (n = 108) to elucidate the relationship between visual processing of fearful facial expressions and interpersonal and affective psychopathic traits. We found that the interpersonal-affective traits of psychopathy were significantly related to fewer fixations to the eyes of fear faces during the emotion recognition task. This association was driven particularly by the interpersonal psychopathic traits (e.g., egocentricity, deceitfulness), whereas fear recognition accuracy was inversely related to the affective psychopathic traits (e.g., callousness, lack of empathy). These findings highlight potential mechanisms for the subset of the interpersonal-affective traits exhibited by psychopathic individuals. (PsycINFO Database Record

A systematic review examining the link between psychopathic personality traits, antisocial behavior, and neural reactivity during reward and loss processing

Antisocial Behavior (AB) has a tremendous societal cost, motivating investigation of the mechanisms that cause individuals to engage and persist in AB. Recent theories of AB emphasize the role of reward-related neural processes in the etiology of severe and chronic forms of AB, including antisocial personality disorder and psychopathy. However, no systematic reviews have evaluated the hypothesis that reward-related neural dysfunction is an etiologic factor in AB in adult samples. Moreover, it is unclear whether AB is linked to a hyper- or hyposensitive reward system and whether AB is related to neural sensitivity to losses. Thus, the current systematic review examined whether AB (including antisocial personality disorder) and psychopathic traits are related to neural reactivity during reward processing, loss processing, or both. Our review identified seven task-based functional MRI or functional connectivity studies that examined associations between neural response to reward and loss, and dimensional and categorical measures of adult AB and/or psychopathy. Across studies, there was evidence that AB is associated with variability in neural functioning during both reward and loss processing. In particular, impulsive-antisocial traits appeared to be specifically associated with hypersensitivity in the ventral striatum during the anticipation, but not the receipt, of rewards.

Associations of Psychopathic Traits With Local and Global Brain Network Topology in Young Adult Women

BACKGROUND

Psychopathic traits vary dimensionally in the population and are associated with multiple negative outcomes. The impaired integration theory (IIT) proposes that psychopathic traits are associated with abnormal neural network topology, such that disturbed integration of neural networks results in a self-perpetuating impairment in rapid integration and learning from multiple components of information. The IIT is based on findings from male offenders presenting high scores on all psychopathic traits. The present study investigated whether IIT predictions of topology abnormalities were associated with psychopathic traits, measured dimensionally, in young adult women with subsyndromal scores.

METHODS

Seventy-three women, with an average age of 25 years, were assessed using the Psychopathy Checklist-Revised and completed resting-state magnetic resonance imaging. Preprocessed time series from 90 anatomical regions were extracted to form connectivity matrices and used to calculate network topology based on graph theory. Correlations between total psychopathy and factor scores with both the raw connectivity matrix and global and local graph theory measures were computed.

RESULTS

Total psychopathy scores and behavioral factor scores were related to connectivity between several pairs of regions, primarily limbic/paralimbic. Psychopathic traits were not associated with global topology measures. Topology abnormalities, robust across network formation thresholds, were found in nodes of the default mode network and in hubs connecting several resting-state networks.

CONCLUSIONS

IIT predictions of abnormal topology of hubs and default mode network nodes with dimensionally measured psychopathic traits were confirmed in a sample of young women. Regional abnormalities, accompanied by preserved global topology, may underlie context-specific abnormal information processing and integration.

Cognitive behavioral interventions for alcohol and drug use disorders: Through the stage model and back again

Cognitive-behavioral therapy (CBT) approaches have among the highest level of empirical support for the treatment of drug and alcohol use disorders. As Psychology of Addictive Behaviors marks its 30th anniversary, we review the evolution of CBT for the addictions through the lens of the Stage Model of Behavioral Therapies Development. The large evidence base from Stage II randomized clinical trials indicates a modest effect size with evidence of relatively durable effects, but limited diffusion in clinical practice, as is the case for most empirically validated approaches for mental health and addictive disorders. Technology may provide a means for CBT interventions to circumvent the "implementation cliff" in Stages III-V by offering a flexible, low-cost, standardized means of disseminating CBT in a range of novel settings and populations. Moreover, returning to Stage I to reconnect clinical applications of CBT to recent developments in cognitive science and neuroscience holds great promise for accelerating understanding of mechanisms of action. It is critical that CBT not be considered as a static intervention, but rather 1 that constantly evolves and is refined through the stage model until the field achieves a maximally powerful intervention that addresses core features of the addictions.

Brain-behavior relationships in externalizing: P3 amplitude reduction reflects deficient inhibitory control

The use of endophenotypes to classify individuals at risk for or suffering from psychopathology has been criticized for lacking specificity and predictive utility. This issue is apparent in research on externalizing, a heritable predisposition to disinhibitory psychopathology and personality traits. Numerous studies have shown that P3 amplitude reduction (P3AR) reliably reflects externalizing, implicating P3AR as a candidate endophenotype for externalizing psychopathology. However, this endophenotype has not been connected directly to a key deficit in executive function (e.g., inhibitory control) commonly related to externalizing. Using a modified oddball task in a sample (N=74) of at-risk adolescents and young adults, we examined the associations among externalizing, P3AR, and inhibitory control. We also examined the associations of P3AR and inhibitory control with frequency of real-world disinhibited behavior. Results indicated that externalizing related to P3AR, which in turn related to deficient inhibitory control. Additionally, there were both unique and interactive associations of P3 amplitude and inhibitory control with indicators of real-world behavior. These findings provide the first direct evidence that P3AR reflects deficits in inhibitory control, thus linking this externalizing-related endophenotype to a specific cognitive process. Moreover, the results highlight the value of considering psychobiological measures alongside behavioral measures for indexing risk for externalizing behavior and psychopathology.

Biobehavioral Approaches to Aggression Implicate Perceived Threat and Insufficient Sleep: Clinical Relevance and Policy Implications

Besides reducing the burden of aggression and violence on society, the biobehavioral study of aggression can inform our understanding of emotional problems and maladaptive behaviors more broadly, since aggression can often co-occur with psychological disorders (e.g., depression). This article reviews the neuroscience/psychophysiology literature to explain brain processes in aggression that can be targeted to reduce its scourge on society. In particular, the review implicates brain circuitry that is often triggered by feelings of threat, which in turn disrupt higher order cognitive processes and may prompt aggression. One potentially modifiable factor less frequently considered in the study of aggression is sleep insufficiency or problems. The neurophysiological impact of sleep insufficiency can parallel the brain-related risk factors of aggression. Policy recommendations span individual mental health innovations, community-based interventions, and public health campaigns promoting healthy lifestyles to reduce aggression and violence.

Relations Between Self-Reported Adverse Events in Childhood and Hypersexuality in Adult Male Sexual Offenders

Hypersexuality, or extreme normophilic sexual urges and behaviors, is a controversial construct that was recently considered as a candidate disorder for the DSM-5 and was rejected. It was also rejected for inclusion in Section III (Conditions for Further Study). Nonetheless, it has been found to be an important predictor of recidivism among sex offenders, and it continues to be discussed widely in the literature. In the present study, we investigated the developmental roots of this construct in a sample of 529 adult male sexual offenders, who were administered the Multidimensional Assessment of Sex and Aggression. Physical, psychological, and sexual abuse experiences were estimated using several scales of early development. Psychological abuse in childhood and adolescence, especially by a father, was found to be the most prominent predictor of subsequent hypersexual thoughts and behaviors. The accumulation of abuse types, however, was also associated with a monotonic increase in the latent trait of hypersexuality. The consequences of these results for conceptualizations of the construct are discussed.

Mapping the developmental pathways of child conduct problems through the neurobiology of empathy

The notion that antisocial behavior reflects failures of empathy has a long history in the clinical literature, yet only recently has evidence emerged to support neuroscientific accounts of empathy and the development of child conduct problems. Much of this evidence has come from research into callous-unemotional traits, which correspond to the affective component of psychopathy and therefore encompass deficits in empathy within a broader cluster of emotional impairments. In this review we integrate current evidence concerning the biobehavioral bases of empathy and callous-unemotional traits, and discuss how it may inform models of heterogeneous subgroups of individuals with early onset conduct problems. We argue that somewhat distinct failures of empathy map onto distinct risk pathways to early onset conduct problems, and that these pathways may be best understood by examining empathy in terms of cognitive and environmental prerequisites and the various neurochemical systems implicated therein.
