Insensitivity to Suffering: Psychopathic Traits and Perception of Others' Pain.

Despite growing evidence that psychopathy entails reduced emotional processing, the relationship between psychopathic traits and third-person pain perception is poorly understood. This study directly examined perception of others' pain in a sample of male and female students (N = 105) who completed the Self-Report Psychopathy scale (SRP-III) and the Toronto Empathy Questionnaire (TEQ). Participants watched a video of 60 one-second clips of other people experiencing pain. Following each clip, participants rated the perceived level of pain intensity and pain unpleasantness. Psychopathic traits were unrelated to response bias, suggesting that individuals high in psychopathic traits were no more or less likely to impute pain to others. However, higher levels of psychopathic traits, particularly callous affect and antisocial behavior, were associated with a decreased ability to discriminate others' pain. Sensitivity and response bias were unrelated to TEQ scores. These findings provide novel insights into the influence of psychopathic traits on emotional processing.

Effects of Primary and Secondary Psychopathy on Deontological and Utilitarian Response Tendencies: The Mediator Role of Alexithymia.

(1) Background: The purpose of this study is to provide more nuanced insights into the effects of sub-dimensional levels of psychopathy on moral dilemma judgments. To this end, this study examined the effects of primary and secondary psychopathy on utilitarian and deontological response tendencies. Moreover, this study also explored the mediating role of alexithymia as well as the moderating role of gender in these effects. (2) Methods: A total of 1227 participants were recruited through the online questionnaire service wjx.cn. After deleting unfinished questionnaires, the remaining 1170 participants were included in the final data analysis. Each participant completed a demographic information questionnaire, the Levenson Self-Report Psychopathy Scale, the Toronto Alexithymia Scale-20, and six pairs of moral dilemmas. Descriptive and correlational analyses of study variables were conducted in SPSS 22.0. Mediation and gender difference analyses were conducted in AMOS 23.0. (3) Results: Primary psychopathy was negatively correlated with deontological response tendencies and uncorrelated with utilitarian response tendencies. By contrast, secondary psychopathy also correlated negatively with deontological response tendencies, but it correlated positively with utilitarian response tendencies. Mediation analysis revealed that alexithymia only mediated the relationship between secondary psychopathy and deontological response tendencies. Multi-group analysis revealed that there was no difference between females and males in the indirect effect model. (4) Conclusions: People with high primary psychopathy are less likely to reject harm in moral dilemmas. By contrast, people with high secondary psychopathy have high alexithymia, which causes them to be less concerned about avoiding harm, and they are more likely to maximize outcomes in moral dilemmas. These findings shed new light on the moral dilemma judgments of individuals with primary and secondary psychopathy.

Examining the Psychometric Properties of the Expanded Levenson Self-Report Psychopathy Scale in Community and University Samples.

The aim of the current study was to further examine the psychometric properties of the Expanded Levenson Self-Report Psychopathy Scale (E-LSRP; Christian & Sellbom, 2016). Specifically, its reliability, internal structure, and convergent and discriminant validity were evaluated using university (N = 367) and community samples (N = 205) from Aotearoa New Zealand. The results provided support for the reliability and validity of the E-LSRP in both samples. More specifically, the internal consistency estimates of the E-LSRP were above the meaningful threshold, indicating good reliability. Furthermore, using confirmatory factor analysis, the hypothesized three-factor structure was supported and conceptually consistent with Cooke and Michie's (2001) Psychopathy Checklist-Revised (PCL-R) three-factor model. Lastly, the results generally provided support for the convergent and discriminant validity of the E-LSRP subscales; the E-LSRP Egocentricity was associated with criteria relevant to interpersonal impairment, the Callous scale with criteria relevant to the affective psychopathy domain, and the Antisocial scale with criteria representing behavioral dysfunction. Overall, the E-LSRP is a promising tool for assessing psychopathy in nonincarcerated populations.

Characterizing vulnerable and grandiose narcissism, Machiavellianism and psychopathy in community-dwelling adult women: The role of cognitive styles, dispositional aggression and deviance, and personality traits

To evaluate how selected cognitive styles (i.e., ideas of reference and fantasy proneness), dispositional aggression and social deviance, and personality traits could help understanding similarities and differences among vulnerable narcissism (VN), grandiose narcissism (GN), Machiavellianism, and psychopathy in women, 986 Italian community-dwelling participants were administered the Italian translations of the Revised Green et al., Paranoid Thoughts Scale Part A (R-GPTS-A), Creative Experience Questionnaire (CEQ), Aggression Questionnaire (AQ), Self-Report Delinquency Scale (SRDS), and Big Five Inventory (BFI). Participants received also the Five Factor Narcissism Inventory-Short Form (FFNI-SF), MACH-IV, and Expanded-Levenson Self-Report Psychopathy Scale (E-LSRP) to assess VN and GN, Machiavellianism, and psychopathy, respectively. Multiple regression analyses showed that R-GPTS-A, CEQ, AQ, SRDS, and BFI trait scale scores explained a substantial amount of variance in the FFNI-SF VN (R2 = 0.62) and GN (R2 = 0.49) scale scores, MACH-IV scores (R2 = 0.29), and E-LSRP scores (R2 = 0.51). Dispositional aggression (i.e., AQ total score) represented a feature common to VN, GN, Machiavellianism, and psychopathy, whereas ideas of reference, fantasy proneness, social deviance, and personality traits yielded differential relationships with the dependent variables.

Aggressive behaviour in antipsychotic-naive first-episode schizophrenia patients, their unaffected siblings and healthy controls.

While patients with schizophrenia are more likely to be victims rather than perpetrators of aggressive behaviour, prior research has shown increased rates of aggressive behaviours in these patients that appear very early in the course of illness. We aimed to assess aggression in antipsychotic-naive first-episode schizophrenia patients, their healthy siblings, and controls; and to investigate correlates of aggression in the patients group. Patients (N=55), siblings (N=55) and healthy controls (N=71) were evaluated on Buss and Perry Aggression Questionnaire (AQ), Life History of Aggression (LHA), Barratt Impulsiveness Scale, and Levenson Self-Report Psychopathy Scale. Age, gender and substance use were regarded as covariates, and differences between the three groups were evaluated using analysis of covariance. Hierarchical regression was performed to determine which variables were associated with aggression level in the patients group. The Tukey multiple comparison test showed that both patients (p < .001) and siblings (p=.023) scored higher on the LHA Aggression than controls. Siblings scored higher than controls (p=.010) for the Anger subscale of the AQ. Patients scored significantly higher than controls in the three impulsiveness dimensions; whereas siblings scored higher than controls in the motor (p=.023) and non-planning (p=.004) dimensions. Multivariate analyses showed that, after controlling for confounders, only attentional impulsiveness (β=.446, p=.0244) and psychopathy traits (β=.359, p=.010) helped predict AQ total scores among patients. Aggression and some of its risk factors including impulsiveness are likely to be trait variables that might provide important vulnerability markers for people at heightened risk of developing psychosis.

Psychometric psychopathy: Relationships with indices of reinforcement sensitivity theory factors

The current study examined relationships between psychopathy factor severity and individual differences in reinforcement sensitivity theory factors. Phase 1 examined relationships between factors from the Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ) and the two-factor model of psychopathy using the Levenson Self-Report Psychopathy Scale (LSRP) in 2914 undergraduate students (63% women). Multigroup observed variable path analyses revealed unique associations between RST-PQ factors and the two factors of psychopathy. Also, small differences in relationship strength across biological sex were observed. Phase 2 examined the two factors of psychopathy in relation to hedonic ratings from the behavioral Sweet Taste Test (STT), along with self-report measures of trait pleasure, in a subset of participants (n = 93; 66% women). Analyses revealed robust sex interactions in relationships between STT ratings and the two psychopathy factors. Men with greater secondary psychopathy severity predicted a reduced slope of liking ratings to increasing concentrations of sucrose, while women showed a positive hedonic slope for secondary and a negative hedonic slope for primary psychopathy. Future research should include analyses for possible moderation of sex and incorporate menstrual cycle status in women when examining measures collected in the laboratory.

Altered effective connectivity from the posterior insula to the amygdala mediates the relationship between psychopathic traits and endorsement of the Harm foundation

Psychopathic traits have been demonstrated to be associated with different moral foundations. However, the neuropsychological mechanism underlying the relationship between psychopathic traits and moral foundations remains obscure. Our study examined the effective connectivity (EC) of psychopathy-related brain regions and its association with endorsement to moral foundations (Harm, Fairness, Loyalty, Authority, and Purity)—combining questionnaire measures, resting-state fMRI (RS-fMRI), and Granger causality analysis. We administered the Levenson Self-Report Psychopathy Scale and Moral Foundation Questionnaire to 78 college students after RS-fMRI scanning. Our results showed that total and primary psychopathy negatively predicted endorsement of the Harm foundation. The EC from the posterior insula to the amygdala was negatively associated with primary psychopathy but positively associated with endorsement of the Harm foundation. Altered posterior insula-amygdala EC partially mediated the relationship between primary psychopathy and endorsement of the Harm foundation. Our findings demonstrated that individuals with elevated psychopathic traits may have atypical processes in recognizing and integrating bodily state information into emotional responses —leading to less concern for harm-related morality. Our findings deepen the understanding of the neuropsychological mechanism underlying the relationship between psychopathic traits and morality, providing potential neurobiological explanations for increased moral transgressions, especially those harm-related transgressions, committed by psychopathic individuals.

Evaluating self-reported psychopathy and associations with personality traits outside the WERID countries: evidence from two Arabic speaking Middle Eastern countries

ABSTRACT The prevalence, manifestation and assessment of psychopathy might be influenced by culture. However, the vast majority of research on psychopathy has been carried out in a few Western, Educated, Industrialized, Rich and Democratic (WEIRD) countries. In contrast, there is limited knowledge in the Middle Eastern Arabic speaking countries for psychopathy. A large sample of under-graduate university students (N = 850) from two Arab countries (Egypt and Kuwait) administered the original version of the Levenson Self-Report Psychopathy Scale (LSRP) along with the NEO-Five Factor Inventory (NEO-FFI). The LSRP is better organized using a three-factor structure (Egocentrism, Callousness, and Antisocial) rather than its original two-factor model (primary and secondary psychopathy) and the reliabilities of all factors were found to be acceptable to high. In addition, all factors correlated negatively with agreeableness, conscientiousness, and extraversion but positively with neuroticism. These results provide initial evidence for cross-cultural similarity of psychopathy construct.

Agreeableness explains the factor structure of the Self-Report Psychopathy Scale, Fourth Edition.

The five-factor model (FFM) is a general personality model that has been frequently studied in its relation to psychopathy (Lynam & Miller, 2015; Widiger & Lynam, 1998) with ample evidence that Antagonism (low Agreeableness) plays a core role in the conceptualization of psychopathy. The present study examined the relations between the Self-Report Psychopathy Scale, Fourth Edition (SRP-4; Paulhus et al., 2014), one of the most commonly used self-report measures of psychopathy and the FFM. Using a preregistered analytical approach, we found that all 4 subscales and the total score of the SRP-4 are positively correlated with all facets of Antagonism and that Antagonism accounts for the overlap between SRP-4 subscales, as introducing these facets to a hierarchical regression reduced the overlap between subscales by more than 50%. Adding Conscientious to the model did not account for further reduction in overlap between the factors. Finally, a structural equation model showed the latent correlation between Antagonism and psychopathy as captured by the SRP-4 to be effectively 1.0, again highlighting the role of Antagonism in the SRP-4's conceptualization of psychopathy. The results were consistent across 2 large samples (Ns of 627 and 628). This study suggests the SRP-4 is assessing Antagonism and showcases the primary role of Antagonism in psychopathy.

Effects of childhood trauma in psychopathy and response inhibition.

Childhood trauma is linked to impairments in executive function and working memory, thought to underly psychological disorders including depression and posttraumatic stress disorder. Research demonstrates that childhood trauma can partially mediate posttraumatic stress disorder in those with executive function deficits. Despite a link with executive function deficit, psychopathy as a consequence of trauma is yet to be studied in this context. The present study investigates the possibility of a relationship between childhood trauma, psychopathic traits, and response inhibition. Eighty participants were tasked to completed the Childhood Traumatic Events Scale (Pennebaker & Susman, 2013), Levenson's Self-Report Psychopathy Scale (Levenson et al., 1995), and Flanker task of response inhibition (Eriksen & Eriksen, 1974). Scores of trauma exposure, psychopathic traits, and reaction times in the Flanker task were measured. Regression analysis revealed no significance for trauma exposure in predicting psychopathic traits (p = .201) and response inhibition (p = .183), indicating that childhood trauma does not strongly predict susceptibility to psychopathic traits or response inhibition deficits. These findings form an important basis on which to build a further understanding of the consequences of childhood trauma exposure, specifically in terms of understanding how specific cognitive functions may be influenced and providing a clearer understanding of how psychopathic traits develop.

"Spiteful and contemptuous: A new look at the emotional experiences related to psychopathy": Correction to Garofalo et al. (2019).

Reports an error in "Spiteful and contemptuous: A new look at the emotional experiences related to psychopathy" by Carlo Garofalo, Craig S. Neumann, Virgil Zeigler-Hill and J. Reid Meloy (Personality Disorders: Theory, Research, and Treatment, 2019[Mar], Vol 10[2], 173-184). In the article (http://dx.doi.org/10.1037/per0000310), there was an error in the placement of the correlation coefficients in Table 4. In the right-most column, the first row should have read ".20***", and each subsequent coefficient should have been shifted down one row. The bottom row should remain blank. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2018-62012-001.) Psychopathy has long been conceptualized in terms of an absence of emotion. Yet, recent studies have suggested that the experience of other-directed negative emotions may be more intimately linked to psychopathy than previously acknowledged, although there is limited knowledge concerning the experience of such emotions. The present study examined the disposition to experience two other-directed emotions, spitefulness and contempt, that are conceptually linked with psychopathy but currently are limited in empirical support. Across 2 studies with 3 nonclinical samples (Ns = 1,237, 239, 521), we found evidence that psychopathic traits-as assessed via the Self-Report Psychopathy Scale (SRP; Paulhus, Neumann, & Hare, 2016; Study 1 and Study 2) and the Triarchic Psychopathy Measure (TriPM; Patrick, 2010; Study 2)-were positively associated with spitefulness (Study 1) and contempt (Study 2). These associations were consistent across psychopathy instruments (SRP and TriPM) and dimensions (i.e., the SRP Interpersonal, Affective, Lifestyle, and Antisocial facets, and the TriPM Meanness and Disinhibition dimensions), were stronger for the interpersonal and affective traits of psychopathy, and held when accounting for several theoretically relevant covariates. The only exception concerned the TriPM Boldness scale, which had less consistent associations with contempt. The present findings further our understanding of the emotional experiences related to psychopathy, highlighting the relevance of focusing on other-directed negative emotions, especially those that are interpersonal in nature and share an antagonistic component.

THE RELATIONSHIP BETWEEN DARK TRIAD AND EMOTIONAL INTELLIGENCE

Objectives. The presence of the so-called Dark Triad (Narcissism, Machiavellianism, and Psychopathy) can be toxic to those around, can lead to counterproductive behaviors and dysfunctional behaviors. On the other hand, people who are successful in personal and professional life are considered to have a high level of emotional intelligence, numerous studies showing that this is a predictor of good functioning and personal, social and organizational adaptation. This study investigates the relationship between the “dark side” of personality and emotional intelligence, and whether or to what extent Narcissism, Machiavellianism, and Psychopathy are negative predictors of emotional intelligence. Material and methods. One hundred and thirty-four individuals aged 21 to 71 years (M = 42.11, SD = 11.68; Females = 71.1%) took part in this study. The following tools were used: Narcissistic Personality Inventory, The Short Dark Triad Scale, Levenson Self-Report Psychopathy Scale and Battery of Emotional Intelligence profile. Results. The regression coefficients were calculated, controlling the role of the other predictors (age, gender, marital status). Narcissism was not a predictor of emotional intelligence (r = .097, p&gt; 0.01). Age and psychopathy were significantly negatively related with the criterion; the gender did not correlate and was removed from the regression model. Emotional intelligence and Machiavellianism did not correlate either positively or negatively, so this dimension cannot be predictor. Conclusions. As predictors of emotional intelligence, the three dimensions, although in many studies have been negatively correlated, in this study this is partially confirmed. Only psychopathy has a negative relationship, it predicts but to a small extent emotional intelligence. Keywords: dark triad, Psychopathy, Machiavellianism, Narcissism, emotional intelligence.

Psychopathic Traits and Cyber Dating Abuse: Mediating Effect of Internet Addiction in a University Student Sample

ABSTRACT Young adults are highly involved on the Internet. However, an excessive involvement can lead to Internet addiction. The literature reveals that the presence of psychopathic traits is associated with a greater predisposition to develop an addiction. With technologies, a new form of dating abuse has emerged – cyber abuse. This cross-sectional study aimed to analyze the associations between the variables under study and to test the mediating effect of Internet addiction between psychopathy and cyber dating abuse. The sample consisted of 249 university students (M = 21.38; SD = 4.52), in Portugal. The Self-Report Psychopathy Scale – III (SRP-III), the Internet Addiction Test (IAT), the Cyber Dating Abuse Questionnaire (CDAQ) and a sociodemographic questionnaire were used as instruments. The main results suggest that Internet addiction partially mediated the relationship between psychopathy and victimization (β = .277; p = .007) and perpetration (β = .243; p = .015) of cyber dating abuse. It is possible to emphasize the importance of the preponderance of psychopathy in the development of addiction and cyber abuse. The results also demonstrated that Internet addiction is influenced by psychopathic traits and that, consequently, it influences cyber dating abuse.

Psychopathy and the perception of the genuineness of facial expressions

Individuals with psychopathic traits are thought to have deficits in emotion recognition, yet they are also known for being manipulative and conning, a skill that necessitates sensitivity to social cues. One unanswered question is whether psychopathic individuals can recognize subtleties in the expression of emotion, such as whether an expression is genuine or not. We examined relationships between psychopathy and ratings of the “genuineness” of pictures of facial expressions. Undergraduate participants (n = 453; 32.5% identifying as men) completed the Triarchic Psychopathy Measure and the Self-Report Psychopathy Scale III. They viewed images that depicted faces displaying either fake (forced, posed) or genuine expressions of happiness, sadness, surprise, and fear and rated how fake versus real they thought the expression was. Controlling for gender, psychopathic traits on both measures were associated with making less of a distinction between fake and real images. Individuals higher in psychopathy rated genuine expressions as less real than those lower in psychopathy. Analyses of psychopathy factors revealed a distinct finding for Boldness (interpersonal dominance and fearlessness), which was associated with rating real smiles as more real. Overall, the findings suggest that individuals higher in psychopathy may perceive the sincerity of emotions differently, which may influence their social behavior.

Connectome-based model predicts individual psychopathic traits in college students

BackgroundPsychopathic traits have been suggested to increase the risk of violations of socio-moral norms. Previous studies revealed that abnormal neural signatures are associated with elevated psychopathic traits; however, whether the intrinsic network architecture can predict psychopathic traits at the individual level remains unclear. MethodsThe present study utilized connectome-based predictive modeling (CPM) to investigate whether whole-brain resting-state functional connectivity (RSFC) can predict psychopathic traits in the general population. Resting-state fMRI data were collected from 84 college students with varying psychopathic traits measured by the Levenson Self-Report Psychopathy Scale (LSRP). ResultsFunctional connections that were negatively correlated with psychopathic traits predicted individual differences in total LSRP and secondary psychopathy score but not primary score. Particularly, nodes with the most connections in the predictive connectome anchored in the prefrontal cortex (e.g., anterior prefrontal cortex and orbitofrontal cortex) and limbic system (e.g., anterior cingulate cortex and insula). In addition, the connections between the occipital network (OCCN) and cingulo-opercular network (CON) served as a significant predictive connectome for total LSRP and secondary psychopathy score. ConclusionCPM constituted by whole-brain RSFC significantly predicted psychopathic traits individually in the general population. The brain areas including the prefrontal cortex and limbic system and large-scale networks including the CON and OCCN play special roles in the predictive model—possibly reflecting atypical cognitive control and affective processing for individuals with elevated psychopathic traits. These findings may facilitate detection and potential intervention of individuals with maladaptive psychopathic tendency.

Susceptibility of the Self-Report Psychopathy Scale (SRP 4) to response distortion and the utility of including validity indices to detect deception.

Self-report psychopathy scales are increasingly used in research and practice despite criticisms that they may be susceptible to response distortion and bias. We assessed the utility of including the Virtuous Responding (VR) and Deviant Responding (DR) validity scales from the Psychopathic Personality Inventory-Revised (PPI-R) for identifying underreporting and overreporting, respectively, on both the full and short-form versions of the Self-Report Psychopathy scale (SRP 4 and SRP-SF) in a pre/post experimental design. Using a sample of 384 male community members and a clinical comparison group of 99 males from a forensic outpatient program, we demonstrated that SRP scores were more susceptible to overreporting than underreporting, and that overreporting significantly and negatively affected convergent validity. Finally, baseline psychopathy scores were unrelated to successful response distortion (i.e., changing scores in correct direction while remaining undetected by the validity scales). It is recommended that assessments using self-report psychopathy scales consider including validity indices to detect response distortion. In doing so, it will be important to consider that general impression management may be conceptually distinct from specific forms of response distortion, such as the intentional amplification or minimization of psychopathic traits.

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

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

Risk assessment of recidivism in Latin America: assessing the reliability and validity of the Self-Appraisal Questionnaire

ABSTRACT Structured risk assessment tools are widely used across the criminal justice systems in western countries. However, little research has been conducted to validate these tools in low and middle-income societies. The aim of this study was to validate a cost-efficient risk assessment tool, the Self-Appraisal Questionnaire (SAQ) in Uruguay, Latin America. The SAQ was administered to a sample of 333 adult male inmates in combination with data from the case file information at the Prison System and self-report. Results showed significant evidence of SAQ’s score reliability (Cronbach α = .91) and concurrent validity with the Self-Report Psychopathy Scale Short Form (r = .62, p < .001). Furthermore, the SAQ showed satisfactory concurrent validity with official data and self-report data for recidivism (AUC = .71 and .75) and for violent recidivism (AUC = .76 and .77). Implications for future research in low and middle-income countries are discussed.

Psychopathy, charisma, and success: A moderation modeling approach to successful psychopathy

Psychopathic traits are associated with negative outcomes; however, they have also been associated with adaptive outcomes (e.g., corporate success, etc.). We tested the Moderated-Expression Model of psychopathy in a sample of community adults (N = 315; 50.8% female; 22–65 years) utilizing a battery of self-report measures (Self-Report Psychopathy Scale; Triarchic Psychopathy Measure; Conger & Kanungo Scale of Charismatic Leadership; General Charisma Inventory; Evading Detection/Punishment; and Occupational Success). The effect of psychopathic traits on evading detection and punishment (not occupational success) was moderated by leadership (and to a lesser extent, general) charisma, net of the effects of pathological narcissism and several other covariates. These results support the Moderated-Expression Model and warrant further research on the associations among psychopathy, charisma, and success.

Psychopathy and Economic Behavior Among Prison Inmates: An Experiment.

This paper investigates whether there is a connection between psychopathy and certain manifestations of social and economic behavior, measured in a lab-in-the-field experiment with prison inmates. In order to test this main hypothesis, we let inmates play four games that have often been used to measure prosocial and antisocial behavior in previous experimental economics literature. Specifically, they play a prisoner's dilemma, a trust game, the equality equivalence test that elicits distributional preferences, and a corruption game. Psychopathy is measured by means of the Levenson Self-Report Psychopathy Scale (LSRP) questionnaire, which inmates filled out after having made their decisions in the four games. We find that higher scores in the LSRP are significantly correlated with anti-social behavior in the form of weaker reciprocity, lower cooperation, lower benevolence and more bribe-oriented decisions in the corruption game. In particular, not cooperating and bribe-maximizing decisions are associated with significantly higher LSRP primary and LSRP secondary scores. Not reciprocating is associated with higher LSRP primary and being spiteful with higher LSRP secondary scores.
