Response perseveration and the triarchic model of psychopathy in an undergraduate sample.

This study aimed to extend previously reported links between distinctive configurations of traits in the psychopathic personality and maladaptive response perseveration, by examining performance in the Card Perseveration Task (CPT) within the framework of the triarchic model of psychopathy in a mixed-gender undergraduate sample. A computerized version of the CPT was administered to 222 undergraduates (142 women) assessed for triarchic psychopathy dimensions using the Triarchic Psychopathy Measure. Maladaptive response perseveration (more cards played and less money earned) was uniquely associated with trait boldness scores for both women and men. Moreover, analyses of response times following feedback indicated that poor performance on the CPT was related to lack of overall reflection. Further mediation analyses did not reveal significant effects of trait boldness on the response perseveration deficit through reflection times. Our results provide new evidence for the role of trait boldness in the failure to suspend reward-approach behavior in the face of increasing punishment contingencies, probably due to an absence of fear or insensitivity to punishment cues rather than to an unreflective response style.

Psychometric Properties of the Clinical Assessment of Prosocial Emotions: Version 1.1 (CAPE 1.1) in Young Males Who Were Incarcerated

The Clinical Assessment of Prosocial Emotions: Version 1.1 (CAPE 1.1) uses structured clinical judgments to diagnose the “with limited prosocial emotions” specifier for Conduct Disorder. This study examined (a) the internal consistency and interrater agreement, and (b) the convergent and divergent validity of the CAPE 1.1 in 72 young males who were incarcerated in two Spanish juvenile detention centers (age range = 14–22 years). The CAPE 1.1 showed good interrater agreement for making the diagnosis of the specifier and adequate internal consistency. The CAPE 1.1 was associated with other measures of callous–unemotional traits, but less consistently associated with other dimensions of psychopathy. Youth who met diagnostic criteria for the specifier scored higher on externalizing problems, but did not differ from other youth who were incarcerated on internalizing problems. These results provide preliminary support for the psychometric properties of the CAPE 1.1 for the clinical assessment of the specifier.

Of malevolence and morality: Psychopathy dimensions are conducive to helping in highly-distressing moral dilemmas

We proposed a context-dependent account of psychopathy and morality which argues that any psychopathy dimension―including those typically theorized to be maladaptive―can be conducive to helping others under appropriate contexts. In Study 1, a college sample (N = 331; Mage = 18.68) completed two-factor and Triarchic psychopathy measures and reported helping behavior, psychological distress, and task prioritization (i.e., greater attentional focus on helping execution vs. helping consequences) after simulating highly-distressing moral dilemmas. In Study 2, a college sample (N = 256; Mage = 18.55) completed the same psychopathy measures and selected one of five intervention tasks—incrementally ranging from slightly to extremely distress-inducing—for an ostensible phobic to perform under conditions in which more distressing tasks were framed as either helpful or harmful. In Study 1, psychopathy dimensions were related to greater helping, which was generally explained best by greater task prioritization. In Study 2, psychopathy dimensions generally related to selecting more distressing tasks for the phobic, even when more distressing tasks were framed as helpful. Thus, psychopathy dimensions appeared conducive to helping in highly-distressing moral dilemmas. Findings contribute preliminary empirical support for a context-dependent account and the possibility of moral manifestations within psychopathy.

Mean, uncommitted, and aggressive: Divergent associations between triarchic psychopathy, elements of love, and caustic relationship behaviors

Two studies explored how the triarchic dimensions of psychopathy predicted relationship outcomes in nonclinical samples. In Study 1, using a predominantly student sample ( N = 100, 24% men, 76% women), results revealed significant negative associations between meanness and Sternberg’s (1997) components of love (intimacy, passion, and commitment). In Study 2, using a more gender-balanced online community sample ( N = 125, 53% men, 47% women), we replicated results from Study 1 and found additional negative associations between self-reported physical aggression, psychological aggression and love in intimate relationships. Further, multivariate analyses revealed that deficits in love explained incremental variance in intimate partner aggression, over and above the triarchic constructs of meanness and disinhibition. Implications for how dimensions of psychopathy manifest in close intimate relationships are discussed.

Who is the Hooligan? The Role of Psychopathic Traits

ABSTRACT The current study aims to examine associations between distinct psychopathic traits with hooliganism, after controlling for the influence of levels of aggression. In addition, we aim to investigate potential associations between psychopathic traits and the likelihood of being involved in hooliganism as leaders or followers. Data were collected from 473 fans (Mage = 22.24, SD = 3.90) from five different Cypriot football teams who completed questionnaires assessing distinct dimensions of psychopathy, aggression, and hooliganism. Findings suggested that callous-unemotional traits was the stronger predictor of hooliganism and the only dimension of psychopathy associated with leadership and the likelihood of being arrested due to hooligan activities, after accounting for levels of aggression. In contrast, grandiose-manipulation was not associated with hooliganism. Individuals high on impulsive-irresponsibility were also likely to engage in hooliganism especially as followers. In addition to explaining the different roles hooligans have in organized activities, the current study provides evidence that callous-unemotional traits and impulsive-irresponsibility can be the basis for the development of interventions targeting hooliganism. The majority of prior work on hooliganism is sociological in nature, and current findings provide evidence for the importance of individual characteristics in explaining this adverse phenomenon.

Improving characterization of psychopathy within the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), alternative model for personality disorders: Creation and validation of Personality Inventory for DSM-5 Triarchic scales.

The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) bridges a significant gap in psychiatric nosology by providing trait-based characterizations of psychopathy along with antisocial personality disorder within the Section III alternative model for personality disorders (AMPD). However, the representation of psychopathy in the AMPD has met with some criticisms (Crego & Widiger, 2014; Few, Lynam, Maples, MacKillop, & Miller, 2015). The current study was undertaken to establish an improved means for characterizing psychopathy in DSM-5 Section III terms, by creating scale measures of triarchic psychopathy dimensions using items from the best-established assessment instrument for the AMPD, the Personality Inventory for DSM-5 (PID-5). Using data from a sample of community adults (N = 210), we employed a construct rating and psychometric refinement approach to develop item-based PID-5 Triarchic scales for measuring psychopathy dimensions of boldness, meanness, and disinhibition. The validity of the PID-5 Triarchic scales was then evaluated in relation to criteria including other scale measures of the triarchic constructs and psychopathy, self-reported antisocial behavior and substance use, empathy, internalizing and other clinical problems, and personality within the development sample and a separate independent sample of adults (N = 240) recruited to have elevated psychopathic traits. Results of this work provide a foundation for improved characterization of psychopathy in terms of the AMPD trait system and provide a mechanism for future research oriented toward clarifying the developmental interface between childhood conduct disorder and psychopathy, as well as identifying neurobiological correlates of dimensions of psychopathy.

Examining Psychopathic Traits in Children Using the Child Psychopathy Scale - Revised.

Applying the affective dimension of psychopathy to youth has advanced understanding of conduct problems in youth, leading to suggestions that other aspects of psychopathy may do the same. This was addressed in the present study by examining the structure and validity of psychopathic traits in elementary-age children as rated by mothers and teachers on the Child Psychopathy Scale - Revised (CPS-R). Participants were 222 children (80.2% male; Mage = 8.92), the majority (71.6%) of whom met criteria for both ADHD and conduct problems. Confirmatory factor analysis supported a four-factor model consisting of prosocial-empathic (PE), grandiose-manipulative (GM), emotionally volatile (EV), and attentive-planful(AP) factors. The CPS-R demonstrated good criterion validity with well-established measures of child behavior problems and callousness. The EV and AP factors demonstrate incremental validity by moderating the relation between conduct problems and impairment. Latent profiles supported a three-profile solution for mothers and a four-profile solution for teachers, with profiles consisting of one group low, one group moderate, and one high on all measures for both informants, and a fourth group that was high on all measures except CD and limited PE. Profiles differed significantly from each other on callousness and impairment, with limited PE being the best differentiator of youth highest in antisocial behavior based on mother and teacher report. Findings suggest that mothers and teachers may be able to identify children at risk for a more negative trajectory of antisocial behavior, that it is worthwhile to examine multiple psychopathy dimensions (rather than just the affective dimension), and that the CPS-R may be useful to screen for youth who are most likely to display more severe antisocial behavior and impairment.

The role of gender in the relations among Dark Triad and psychopathy, sociosexuality, and moral judgments

The Dark Triad (D3) traits of narcissism, Machiavellianism, and psychopathy have been linked to a range of moral behavior, and to sociosexuality and sexual behavior, particularly in males. The current study examined whether males and females differ with respect to relations among D3 traits and dimensions of psychopathy from the Triarchic Psychopathy Measure (TriPM), sexual behavior, sociosexuality, tendency towards infidelity, and moral judgments, using a community sample. D3 and TriPM measures were generally more strongly correlated with sexual behavior for males in ways that might increase numbers of matings and sexual partners, but were more strongly correlated with intention towards infidelity and sociosexual attitudes for females—in ways that might facilitate extra-pair mating. Sociosexuality and self-reported sexual behavior showed a strong pattern of overall and gender-specific relations to moral judgments. D3 and psychopathy measures were also related to everyday moral judgments, although generally less so than were sociosexuality and sexual behavior. These results clearly point to the importance of taking gender into account when considering the relations between D3 traits, sexual behavior, sociosexuality, and moral judgments.

Maladaptive personality and psychopathy dimensions as predictors of music and movie preferences in US adults

We link modern conceptualizations of maladaptive personality and psychopathy dimensions to music and movie genre preferences. Participants, N = 379, completed the Personality Inventory (5th ed.; PID-5), Triarchic Psychopathy Measure (TriPM), and music and movie preferences questionnaires. The structure of some, but not all, music preferences factors aligned with previous reports. Overall, maladaptive traits had meaningful, albeit modest links to entertainment media preferences, but not to the kinds of intense or rebellious music genres sometimes labeled as “problem” entertainment in prior literature. Support emerged for several a priori hypotheses, but some predictions based on the three- and five-factor normal personality trait and entertainment preferences literature did not generalize to a five-factor formulation of maladaptive personality. We discuss the findings’ implications and several likely sources of inconsistencies in the literature on music and movie preferences and personality.

Emotional modulation of the pupil response in psychopathy.

Psychopathy is a form of personality disorder associated with a deficit in emotional processing. However, there is debate whether this deficit applies to all emotions or exists only for negative emotions. The pupil dilates rapidly in response to emotional stimuli, allowing a time-sensitive index of emotional processing. Across 3 experiments using (a) visual images of real-world scenes, (b) auditory sound clips, and (c) videos of dynamic facial expressions, we measured emotional modulation of the pupil response to both negative and positive stimuli. Participants were 82 male mentally disordered offenders. Psychopathy was measured using the Psychopathy Checklist—Revised to produce factor scores of interpersonal–affective traits (Factor 1) and lifestyle–antisocial traits (Factor 2). Participants with high Factor 1 scores showed reduced emotional modulation of the pupil response to negative images and angry faces but not to any of the positive stimuli. These effects only occurred shortly after the emotion was presented (<2,000 ms), suggesting delayed processing of negative affective stimuli in Factor 1 psychopathy. Factor 2 scores were not associated with any changes in pupil response. There were no effects of psychopathy on the pupil response to the affective sound clips. The results support a specific psychopathic deficit in the processing of negative stimuli related to the interpersonal–affective dimension of psychopathy. We argue that pupillometry is a powerful and noninvasive tool to investigate emotional processing in clinical populations.

The Childhood and Adolescent Taxon Scale – Self-Report: Validity Among Male and Female Youths from Forensic and School Contexts

This study provides the first examination of the Childhood and Adolescent Taxon Scale – Self-report (CATS-SR) proxy measure of the persistent antisocial behavior dimension of psychopathy, based on childhood and adolescent history, in a European context and with female youth. The CATS-SR is evaluated in a sample of 1,134 male and female youth recruited from forensic or school settings in Portugal. The CATS-SR did not significantly differ for male and female youth seen in forensic settings, but was higher in male than female youth recruited from schools, and higher in youth seen in forensic than in school settings. The CATS-SR was positively and moderately correlated with self-report psychopathy construct measures that included items tapping interpersonal and affective facets of psychopathy such as callousness and impulsivity. It also correlated as expected with age of first criminal contact, crime seriousness, conduct disorder diagnosis, drug use, and having unprotected sex. The findings suggest that the CATS-SR has discriminant, convergent, and criterion-related validity, and could therefore be useful in assessments of the persistent antisocial dimension of psychopathy.

Psychometric Properties and Construct Validity of the Short Version of the Self-Report Psychopathy Scale in a Southern European Sample

The Self-Report Psychopathy Scale–Short Form (SRP–SF) is a brief measure of psychopathy, developed via model-based test theory. The SRP–SF has a 4-factor structure with items reflecting affective, interpersonal, lifestyle, and antisocial domains, in line with the Psychopathy Checklist–Revised (PCL–R), which can be aggregated to form the traditional F1 and F2 dimensions of psychopathy. Previous research indicates the SRP is a viable tool for examining the prevalence of psychopathic propensities and their correlates in nonoffender populations. Currently, a substantial amount of nonoffender research on psychopathy is conducted in North America. Here, we inspect the psychometric properties of the SRP–SF and probe its association with general personality and empathy in a large southern European (Portuguese) community sample. Consistent with previous studies, results indicated good fit for the 4-factor model, including for separate female and male subsamples, good internal consistency across its scales and subscales, and the predicted pattern of associations with the correlates of psychopathy. The results of this cross-cultural study provide further evidence of the validity of the SRP–SF in the assessment of psychopathy in community samples, and help to extend the nomological net on the larger construct to a southern European sample.

Clarifying the association between psychopathy dimensions and internalizing symptoms in two community samples: The role of general personality

Research suggests that the Boldness and Disinhibition traits of psychopathy are negatively and positively related to internalizing, respectively. Although the associations between psychopathy and internalizing are relatively well-demonstrated, few studies have examined the specificity of these associations with psychopathy as opposed to general personality. We sought to replicate and extend existing research by examining the relationships between multiple conceptualizations of psychopathy and internalizing (depression, generalized anxiety, social anxiety, anger) in two community samples (N1 = 430; N2 = 441). We also investigated (a) the contributions of general personality, (b) the possibility that Boldness traits are statistically protective against internalizing, and (c) gender differences in these relations. Consistent with prior research, boldness traits were negatively associated with internalizing, whereas Disinhibition traits were positively associated; Meanness traits were largely unrelated. General personality traits accounted for the majority of the relationships between psychopathy and internalizing, although Disinhibition traits were unique correlates of internalizing above-and-beyond general personality. We did not find robust evidence that Boldness buffers Disinhibition's relationships with internalizing, nor that gender moderated the relationships between psychopathy and internalizing. These results may bear meaningful implications regarding the conceptualization and assessment of internalizing disorders and psychopathy.

Not Just for Adults: Using the Triarchic Model of Psychopathy to Inform Developmental Models of Conduct Problems in Adolescence

The triarchic model of psychopathy was advanced to reconcile differing historic conceptions of this condition and alternative approaches for assessing it. The current study was undertaken to expand the empirical evidence base for the triarchic model by examining its correlates in adolescents, with measures of particular relevance to developmental theories of antisocial behavior. Self-report scales assessing the triarchic constructs were administered along with measures of conduct problems, callous-unemotional traits, attachment style dimensions, negative emotionality, and hyperactivity/inattention to 608 Italian adolescents (272 girls; M age = 16.70 years). The disinhibition dimension of the triarchic model was related most highly to general externalizing outcomes, such as conduct problems and hyperactivity-inattention, in this adolescent sample. The meanness dimension was selectively related to callous-unemotional traits and other measures of limited prosocial emotions and to affiliation motives that emphasize social gain. Triarchic boldness was associated with greater emotional stability and greater confidence in peer relationships. Of interest, an interaction between meanness and boldness was evident in predicting a lower need to understand one’s own and others’ emotions. These results provide a valuable illustration of the potential of the triarchic model to help advance developmental models of antisocial behavior in youth. Public Significance Statement This study examined how dimensions of psychopathy described by the triarchic model relate to measures of problem behaviors and affective-interpersonal style in an adolescent sample. Scores on the three triarchic dimensions—disinhibition, meanness, and boldness—showed meaningful contrasting relations with conduct problems, hyperactivity/inattention, callous-unemotional traits, emotional proclivities, and attachment style dimensions. This work illustrates how the triarchic model conceptualization can help advance developmental models of the emergence of antisocial behavior.

Psychopathic Traits in Middle Childhood: Evidence of a Hierarchical Three-Factor Structure

Although the development of psychopathy is not well understood, prior studies suggest that psychopathic traits begin to develop in childhood. Whereas research suggests consistency in the structure and correlates of psychopathic traits as assessed with clinical measures of psychopathic traits in adolescence and in adulthood, there is less agreement about the nature of psychopathic traits earlier in childhood. This study was designed to enhance understanding of the nature of psychopathic traits in youth by: 1) examining the fit of one, two, three, and four factor models of psychopathic traits during middle childhood, and 2) examining the stability of the factor structure of psychopathic traits over time through invariance testing. The participants were youth in the Quebec Longitudinal Study of Child Development (QLSCD) whose teachers provided ratings on 17 items associated with four validated dimensions of psychopathy at six (N = 605), seven (N = 747) and eight years of age (N = 686). Confirmatory factor analyses revealed that a hierarchical three-factor model of psychopathic traits, consisting of interpersonal, affective, and lifestyle/ antisocial components provided the best fit to the data at all three ages. Analyses also demonstrated strong invariance across these ages. These findings provide preliminary evidence that the internal structure for a syndrome of psychopathic traits in middle childhood is somewhat similar but slightly less differentiated than the factor structure identified during adolescence. Current findings also suggest that this internal structure is stable over a three-year period during middle childhood.

Is it possible to change the psychopathic traits of substance abusers treated in faith-based therapeutic communities - does the length of treatment matter?

Background/Aim. Faith-based therapeutic communities (FBTCs) have been increasingly employed as a modality in the treatment of substance abuse. Their program influences behavioral, psychological, cognitive and social changes among their beneficiaries. The aim of the study was to evaluate whether the duration of treatment in a FBTC may contribute to changes in the traits that make the four Hare?s psychopathy dimensions ? Antisocial behavior, Lifestyle, Interpersonal relationships, and Psychopathic affect. Another aim was to assess whether abusers on treatment in a FBTC have more pronounced psychopathic traits compared with subjects with no history of substance abuse. Methods. The study included 59 male subjects, of an average age of 29 years, and of different educational levels, who were divided into three groups: substance abusers who had spent one year in the FBTC; substance abusers who had successfully completed a two-year program in the FBTC; and healthy controls with no history of substance abuse. The Psychopathy Assessment Questionnaire (PAQ) was employed to assess the four Hare?s dimensions of psychopathy. Results. There were statistically significant differences among the groups on the Antisocial Behavior dimension. For this dimension, there were differences among nonabusers and both groups of substance abusers, with nonabusers achieving the lowest average scores. There were no statistically significant differences between two groups of substance abusers in any of the studied dimensions. Conclusion. The longer, two-year treatment in the FBTC did not contribute to changes of the psychopathic traits more than the one-year treatment. In addition, subjects with history of substance abuse undergoing treatment in the FBTC had more pronounced psychopathic traits compared with non-abusers.

Genetic and environmental relations of executive functions to antisocial personality disorder symptoms and psychopathy

Meta-analytic findings suggest that antisocial behavior, broadly defined, may relate to a Common Executive Function (EF) factor that captures covariance across response inhibition, working memory updating, and mental set shifting tasks. However, it is unclear whether this common factor, which is isomorphic with individual differences in response inhibition, accounts for all of the EF variance in antisocial behavior and psychopathy, or if they also relate to updating- and shifting-specific abilities. Moreover, findings that antisocial behavior and lower cognitive ability are particularly associated with the psychopathy dimension reflecting impulsivity and irresponsibility, compared to the dimension reflecting affective–interpersonal functioning, raise the possibility that EF relates to the variance shared between the impulsive–irresponsible psychopathy dimension and antisocial personality disorder. We examined these questions in a young adult twin sample (N = 765) with measures of multiple EF latent variables, Levenson Self-Report Psychopathy (LSRP) Primary (affective–interpersonal) and Secondary (impulsive–irresponsible) scales, and antisocial personality disorder symptoms (ASPDsx). Phenotypically, higher ASPDsx and LSRP Secondary psychopathy, but not LSRP Primary psychopathy, were associated with lower Common EF. Moreover, both psychopathy dimensions were negatively correlated with Updating-Specific ability, which was unrelated to ASPDsx. Results from twin models indicated that the association between LSRP Secondary psychopathy and ASPDsx was due to both genetic and nonshared environmental influences; however, Common EF's association with ASPDsx was primarily genetic, whereas its association with LSRP Secondary psychopathy had a significant environmental component. Thus, the interrelations among these constructs may reflect heterogeneous etiological pathways.

Psychopathy in detained boys: The search for primary and secondary variants in a clinical setting.

This study investigates whether primary and secondary variants of psychopathy can be identified in an applied, forensic setting based on self-reports of psychopathy and anxiety. Data were available for two samples of detained boys (Sample A: N = 847, Sample B: N = 749). Using three psychopathy dimensions and anxiety as clustering variables, latent profile analysis arrived at 4 latent classes (LCs) that were tentatively labeled as control (LC1), high anxiety (LC2), moderate psychopathy (LC3), and high psychopathy (LC4). Boys in LC4 engaged in higher levels of alcohol/drug use, conduct problems, reactive and proactive aggression than their counterparts in LC1 and in higher levels of conduct problems, alcohol/drug use, and proactive aggression than boys in LC3. Findings further indicated that the risk for future nonviolent arrests was the highest in LC4 as compared with LC2 and LC3, though no class differences in risk for future violent arrests emerged. Overall, these findings were well replicated in Sample B. Exploratory analyses included additional measures of negative affect (depressed feeling and anger-irritability), maltreatment, and/or number of past arrests (as proxy of a 4th psychopathy dimension) as clustering variables and identified all but 1 (LC3) of the 4 aforementioned LCs. Notwithstanding that our findings challenge the expected relevance of differentiating primary and secondary variants of youth psychopathy, they do suggest that it is possible to identify detained boys with high levels of psychopathic traits who display features associated with adult psychopathy. Implications for theory, research, and practice are discussed. (PsycINFO Database Record

A Retrospective Study on How Psychopathic Traits Differentiate Recidivists From First-Time Female Youth Offenders in Juvenile Detention Centers

ABSTRACTThe aim of the present study was to analyze the relation between recidivism and self-reported psychopathic traits, more specifically the callous-unemotional, impulsivity, and narcissism dimensions of the psychopathy construct among female juvenile delinquents. The Antisocial Process Screening Device–Self-Report (APSD-SR) and other self-report psychometric instruments (i.e., Inventory of Callous-Unemotional Traits [ICU], Barratt Impulsiveness Scale, version 11 [BIS-11], Narcissistic Personality Inventory-13 [NPI-13]) independently measuring the different dimensions of psychopathy were completed by a sample of incarcerated female juvenile offenders (N = 81) that were retrospectively classified as first-time offenders versus recidivists. The only statistically significant relation between recidivism and psychopathic traits found was with narcissism, namely with the Grandiose/Exhibitionism and the Entitlement/Exploitativeness dimensions of the NPI-13. Our results argue for some utility of self-reported psychopathic traits in retrospectively predicting recidivism among female juvenile delinquents.

Examining Associations Between Psychopathic Traits and Executive Functions in Incarcerated Violent Offenders.

Executive functions (EFs) are essential in almost all aspects of daily life and have been robustly related to antisocial behavior. However, the relationship between psychopathy and EFs has remained equivocal. Research investigating lower-level trait dimensions of psychopathy using standardized EF measures could be beneficial in addressing this issue. In this study, we examined associations between four EFs and four dimensions of psychopathic traits (interpersonal, affective, lifestyle, antisocial) using zero-order correlation and a combination of classical and Bayesian statistical methods. Two hundred and fourteen incarcerated male violent offenders were assessed with the Psychopathy Checklist-Revised and completed tests of cognitive flexibility, spatial working memory, response inhibition, and planning and problem-solving using the Cambridge Neuropsychological Test Automated Battery. Lifestyle psychopathic traits were significantly associated with reduced initial thinking time in a planning and problem-solving task, with a Bayes factor indicating substantial evidence for the observed correlation, and antisocial psychopathic traits showed a significant association with reduced initial thinking time in the same task, although the Bayes factor indicated only anecdotal evidence. Significant associations were also found between affective and antisocial psychopathic traits and less efficient strategic thinking in a spatial working memory task, and between affective, lifestyle and antisocial psychopathic traits and fewer problems solved in a planning and problem-solving task, although these findings were not corroborated by the Bayesian analysis. While the observed effects ranged between small and medium, our study suggests that reduced initial thinking times in planning and problem-solving is robustly associated with higher degrees of lifestyle and antisocial psychopathic traits.
