    Villains, Victims, and Verisimilitudes: An Exploratory Study of Unethical Corporate Values, Bullying Experiences, Psychopathy, and Selling Professionals’ Ethical Reasoning.Sean Valentine, Gary Fleischman & Lynn Godkin - 2018 - Journal of Business Ethics 148 (1):135-154.
    This study assesses the relationships among unethical corporate values, bullying experiences, psychopathy, and selling professionals’ ethical evaluations of bullying. Information was collected from national/regional samples of selling professionals. Results indicated that unethical values, bullying, and psychopathy were positively interrelated. Psychopathy and unethical values were negatively associated with moral intensity, while moral intensity was positively related to ethical issue importance. Psychopathy and unethical values were negatively related to issue importance, and issue importance and moral intensity were positively related to ethical judgment. (...)

    The Hegemony of Psychopathy.Lajos L. Brons - 2017 - Santa Barbara, California: Brainstorm Books.
    Any social and political arrangement depends on acceptance. If a substantial part of a people does not accept the authority of its rulers, then those can only remain in power by means of force, and even that use of force needs to be accepted to be effective. Gramsci called this acceptance of the socio-political status quo “hegemony.” Every stable state relies primarily on hegemony as a source of control. Hegemony works through the dissemination of values and beliefs that create acceptance (...)

    Complex Relations Between Psychopathy and Fitness May Indicate Adaptive Trade-Offs.Janko Međedović - forthcoming - Evolutionary Psychological Science.
    In order to assess the potential of psychopathy to increase evolutionary fitness, we examined the relations between psychopathy and fitness indicators (number of children and grandchildren, problems in physical health both in parents and offspring) in a sample of post-reproductive individuals (N = 187; Mage = 66.52). Specifically, we explored the possibility that psychopathy traits are involved in evolutionary trade-offs: both positive and negative relations with different fitness components. Psychopathy was measured via three traits—interpersonal, affective, and lifestyle characteristics, which are (...)

    Klasične moralne dileme žrtvovanja, u kojima je potrebno žrtvovati život jedne osobe kako bi spasili nekoliko drugih života, često su definirane konfliktom između racionalnog odgovora maksimizacije ukupne dobrobiti (utilitaristička moralna prosudba) i emocionalne averzije na povredu (deontološka moralna prosudba). Novija su istraživanja moralnog prosuđivanja pokazala da su socijalno averzivni stilovi ličnosti povezani sa sklonosti utilitarističkom odgovaranju na moralne dileme. Cilj je ovoga istraživanja bio ispitati povezanosti crta ličnosti tamne trijade i odgovora na moralne dileme, kao i medijacijski efekt emocionalne empatije (...)

    Can Psychopathic Traits Be Adaptive? Sex Differences in Relations Between Psychopathy and Emotional Distress.Janko Međedović & Katarina Sokić - 2018 - Psychological Topics 27 (3):481-497.
    One of the most prominent models of psychopathy operationalizes this construct as consisting of four factors: interpersonal, affective, lifestyle and antisocial traits. These traits show different relationship patterns with other constructs, and these relations may differ in men and women. The aim of this study was to investigate whether the relations between psychopathic traits and indicators of emotional distress (depression, anxiety and stress), differ between men and women. Data was collected on 650 students (60% women) at the University of Zagreb. (...)

    In the present study, we tested the hypothesis that psychopathy emerges as an adaptive behavioral response to a harsh environment: psychopathy could represent a mediator in the link between a harsh environment and fast life history pathway. We measured environmental harshness, psychopathy (boldness, meanness, and disinhibition), and a wide range of life history parameters (expected longevity, covitality, age at first menstruation, age at first sex, mating success, planned age at first reproduction, and expected total fertility) in a sample of young (...)

    High Levels of Psychopathic Traits Alters Moral Choice but Not Moral Judgment.Sébastien Tassy, Christine Deruelle, Julien Mancini, Samuel Leistedt & Bruno Wicker - 2013 - Frontiers in Human Neuroscience 7.
    Psychopathy is a personality disorder frequently associated with immoral behaviors. Previous behavioral studies on the influence of psychopathy on moral decision have yielded contradictory results, possibly because they focused either on judgment (abstract evaluation) or on choice of hypothetical action, two processes that may rely on different mechanisms. In this study, we explored the influence of the level of psychopathic traits on judgment and choice of hypothetical action during moral dilemma evaluation. A population of 102 students completed a questionnaire with (...)

    Instrumental Rationality in Psychopathy: Implications From Learning Tasks.Marko Jurjako & Luca Malatesti - 2016 - Philosophical Psychology 29 (5):717-731.
    The issue whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions on moral psychology and in those concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability for transferring the motivation by means-ends reasoning. In fact, we defend the different claim that these experiments (...)

    Is Psychopathy a Harmful Dysfunction?Marko Jurjako - 2019 - Biology and Philosophy 34 (1).
    In their paper “Is psychopathy a mental disease?”, Thomas Nadelhoffer and Walter Sinnott-Armstrong argue that according to any plausible account of mental disorder, neural and psychological abnormalities correlated with psychopathy should be regarded as signs of a mental disorder. I oppose this conclusion by arguing that at least on a naturalistically grounded account, such as Wakefield’s ‘Harmful Dysfunction’ view, currently available empirical data and evolutionary considerations indicate that psychopathy is not a mental disorder. For an online version of the paper, (...)

    Delineating Psychopathy From Cognitive Empathy: The Case of Psychopathic Personality Traits Scale.Janko Međedović, Tara Bulut, Drago Savić & Nikola Đuričić - 2018 - European Journal of Analytic Philosophy 14 (1):53-62.
    There is an ongoing debate regarding the content of psychopathy, especially about the status of antisocial behavior and disinhibition characteristics as core psychopathy features. Psychopathic Personality Traits Scale (PPTS) represents a novel model of psychopathy based on core psychopathy markers such as Interpersonal manipulation, Egocentricity and Affective responsiveness. However, this model presupposes another narrow trait of psychopathy: cognitive responsiveness, which represents a lack of cognitive empathy. Since previous models of psychopathy do not depict this feature as a core psychopathy trait, (...)

    The diagnosis of psychopathic personality disorder has salience for forensic clinical practice. It influences decisions regarding risk, treatability and sentencing, indeed, in certain jurisdictions it serves as an aggravating factor that increases the likelihood of a capital sentence. The concatenation of symptom that is associated with modern conceptions of the disorder can be discerned in early writings, including the book of Psalms. Despite its forensic clinical importance and historical pedigree the concept remains elusive and controverted. In this paper I describe (...)

    False-Positives in Psychopathy Assessment: Proposing Theory-Driven Exclusion Criteria in Research Sampling.Rasmus Rosenberg Larsen - 2018 - European Journal of Analytic Philosophy 14 (1):33-52.
    Recent debates in psychopathy studies have articulated concerns about false-positives in assessment and research sampling. These are pressing concerns for research progress, since scientific quality depends on sample quality, that is, if we wish to study psychopathy we must be certain that the individuals we study are, in fact, psychopaths. Thus, if conventional assessment tools yield substantial false-positives, this would explain why central research is laden with discrepancies and nonreplicable findings. This paper draws on moral psychology in order to develop (...)

    A Dual-Process Account of Moral Judgment: What Psychopaths Can Teach Us About Morality.Deirdre Kelly - 2016 - Dissertation, Carleton University
    Researchers who argue that moral judgment is based on emotions (`emotion-backers') and those who believe that it is based on reasoning and deliberation (`reasoning-backers') have both struggled to account for the notorious moral deviance of incarcerated psychopaths. Emotion-backers, such as Jonathan Haidt, focus on psychopaths' lack of a affect,or defciencies in particular emotions, such as sympathy. Reasoning-backers, such as Lawrence Kohlberg, focus instead on psychopaths' de cient reasoning. Both accounts offer separate descriptions of what goes wrong in the disorder, but (...)

    Emotional Attentional Capture in Children with Conduct Problems: The Role of Callous-Unemotional Traits.Sara Hodsoll, Nilli Lavie & Essi Viding - 2014 - Frontiers in Human Neuroscience 8.
    Objective: Appropriate reactivity to emotional facial expressions, even if these are seen whilst we are engaged in another activity, is critical for successful social interaction. Children with conduct problems (CP) and high levels of callous-unemotional (CU) traits are characterized by blunted reactivity to other people's emotions, while children with CP and low levels of CU traits can over-react to perceived emotional threat. No study to date has compared children with CP and high vs. low levels of CU traits to typically (...)

    AN INTIMATE INSIGHT ON PSYCHOPATHY AND A NOVEL HERMENEUTIC PSYCHOLOGICAL SCIENCE.E. Taku - manuscript
    This paper is rather a profound hermeneutic enunciation putting into question our present understanding of psychopathy. It further articulates, in complement, a novel theoretical and methodological conceptualisation for a hermeneutic psychological science. Methodology-wise, it puts into question a traditional more or less categorical and mechanical approach to the social and behavioural sciences as it strives to introduce a creative and insightful approach for the articulation of ideas. It rather seeks to construe the scientific method as being more about falsifiability and (...)

    Comparing the Response Modulation Hypothesis and the Integrated Emotions System Theory: The Role of Top-Down Attention in Psychopathy.Jaap Munneke, Sylco S. Hoppenbrouwers, Bethany Little, Karen Kooiman, Erik Van der Burg & Jan Theeuwes - 2018 - Personality and Individual Differences 122:134-139.
    Objective: Two major etiological theories on psychopathy propose different mechanisms as to how emotional facial expressions are processed by individuals with elevated psychopathic traits. The Response Modulation Hypothesis (RMH) proposes that psychopathic individuals show emotional deficits as a consequence of attentional deployment, suggesting that emotional deficits are situation-specific. The Integrated Emotions System theory (IES) suggests that psychopathic individuals have a fundamental amygdala dysfunction which precludes adequate responsiveness to the distress of others. Methods: Participants performed a visual search task in which (...)

    Putting Cognition Into Sociopathy.R. J. R. Blair & John Morton - 1995 - Behavioral and Brain Sciences 18 (3):548-548.
    We make three suggestions with regard to Mealey's work. First, her lack of a cognitive analysis of the sociopath results in underspecified mappings between sociobiology and behavior. Second, the developmental literature indicates that Mealey's implicit assumption, that moral socialisation is achieved through punishment, is invalid. Third, we advance the use of causal modelling to map the developmental relationships between biology, cognition, and behaviour.

    After describing the disorder of psychopathy, I examine the theories and the evidence concerning the psychopaths’ deficient moral capacities. I first examine whether or not psychopaths can pass tests of moral knowledge. Most of the evidence suggests that they can. If there is a lack of moral understanding, then it has to be due to an incapacity that affects not their declarative knowledge of moral norms, but their deeper understanding of them. I then examine two suggestions: it is their deficient (...)

The adverse consequences of antisocial behavior produce great burden for the perpetrators, victims, family members, and for society at-large. The pervasiveness of antisocial behavior highlights the importance of precisely characterizing subtypes of antisocial individuals and identifying specific factors that are etiologically related to such behaviors to inform the development of targeted treatments.

    Recent studies suggest that psychopathy may be associated with dysfunction in the neural circuitry supporting both threat- and reward-related processes. However, these studies have involved small samples and often focused on extreme groups. Thus, it is unclear to what extent current findings may generalize to psychopathic traits in the general population. Furthermore, no studies have systematically and simultaneously assessed associations between distinct psychopathy facets and both threat- and reward-related brain function in the same sample of participants. Here, we examined the (...)

    Philosophers On Psychopaths: A Cautionary Tale in Interdisciplinarity.Jarkko Jalava & Stephanie Griffiths - 2017 - Philosophy, Psychiatry, and Psychology 24 (1):1-12.
    Philosophers typically rely on empirical data when they comment on psychopaths’ moral responsibility. Many argue that psychopaths, as per the data, suffer from significant impairments in the precursors of moral reasoning and behavior, and therefore they should not be held morally responsible for their actions. However, careful analysis of these studies shows that this view is mistaken. We discuss how several philosophers— perhaps following the lead of social scientists—have systematically misinterpreted or simplified psychological data to support their conclusions about psychopaths’ (...)

    We used text analysis software to examine the linguistic features of the speech of 21 psychopathic and 45 other offenders during the interview part of a Psychopathy Checklist–Revised (PCL-R) assessment. Regression analysis was run on the linguistic categories to determine which were the best predictors of psychopathy scores. Relative to the other offenders, psychopaths used more disfluencies (“you know”) and personal pronouns, made fewer references to other people (e.g., personal names, family), and were also less emotionally expressive. In particular, a (...)

    Distinct Neuronal Patterns of Positive and Negative Moral Processing in Psychopathy.Samantha J. Fede, Jana Schaich Borg, Prashanth K. Nyalakanti, Carla L. Hare, Lora M. Cope, Walter Sinnott-Armstrong, Mike Koenigs, Vince D. Calhoun & Kent A. Kiehl - 2016 - Cognitive, Affective, and Behavioral Neuroscience 16 (6):1074–1085.
    Psychopathy is a disorder characterized by severe and frequent moral violations in multiple domains of life. Numerous studies have shown psychopathy-related limbic brain abnormalities during moral processing; however, these studies only examined negatively valenced moral stimuli. Here, we aimed to replicate prior psychopathy research on negative moral judgments and to extend this work by examining psychopathy-related abnormalities in the processing of controversial moral stimuli and positive moral processing. Incarcerated adult males (N = 245) completed a functional magnetic resonance imaging protocol (...)

    Reversal Learning Deficits in Criminal Offenders: Effects of Psychopathy, Substance Use, and Childhood Maltreatment History.Dargis Monika, C. Wolf Richard & Koenigs Michael - 2016 - Journal of Psychopathology and Behavioral Assessment.
    Deficits in reinforcement learning are presumed to underlie the impulsive and incorrigible behavior exhibited by psychopathic criminals. However, previous studies documenting reversal learning impairments in psychopathic individuals have not investigated this relationship across a continuous range of psychopathy severity, nor have they examined how reversal learning impairments relate to different psychopathic traits, such as the interpersonal-affective and lifestyle-antisocial dimensions. Furthermore, previous studies have not considered the role that childhood maltreatment and substance use may have in this specific cognitive deficit. Using (...)

    Impulsive-Antisocial Dimension of Psychopathy Linked to Enlargement and Abnormal Functional Connectivity of the Striatum.Cole Korponay, Maia Pujara, Philip Deming, Clarissa Philippi, Jean Decety, David S. Kosson, Kent A. Kiehl & Michael Koenigs - 2016 - Biological Psychiatry.
    Background -/- Psychopathy is a mental health disorder characterized by callous and impulsive antisocial behavior, and it is associated with a high incidence of violent crime, substance abuse, and recidivism. Recent studies suggest that the striatum may be a key component of the neurobiological basis for the disorder, although structural findings have been mixed, and functional connectivity of the striatum in psychopathy has yet to be fully examined. Methods -/- We performed a multimodal neuroimaging study of striatum volume and functional (...)

    Psychopathic Individuals Exhibit but Do Not Avoid Regret During Counterfactual Decision Making.Arielle Baskin-Sommersa, Allison M. Stuppy-Sullivana Allison & Joshua W. Buckholtz - 2016 - Proceedins of the National Academy of Sciences 113 (50):14438-14443.
    Psychopathy is associated with persistent antisocial behavior and a striking lack of regret for the consequences of that behavior. Although explanatory models for psychopathy have largely focused on deficits in affective responsiveness, recent work indicates that aberrant value-based decision making may also play a role. On that basis, some have suggested that psychopathic individuals may be unable to effectively use prospective simulations to update action value estimates during cost–benefit decision making. However, the specific mechanisms linking valuation, affective deficits, and maladaptive (...)

    Smith and Lilienfeld’s Meta-Analysis of the Response Modulation Hypothesis: Important Theoretical and Quantitative Clarifications.Joseph P. Newman & Arielle R. Baskin-Sommers - 2016 - Psychological Bulletin 142 (12):1384-1393.
    In the first meta-analytic review of the response modulation hypothesis (RMH), an attention-based model for understanding the etiology of psychopathy, Smith and Lilienfeld (2015) report that the average effect size for response modulation deficits in psychopathic individuals fell in the small to medium range (r = .20; p. < .001, d = .41). Moreover, support for the RMH extended to both psychopathy dimensions, across diverse assessments and settings, and spanned child, adult, female, and male samples. The analysis also revealed good (...)

    The Identification of Negative Emotions Through a Go/No-Go Task.C. Iria, F. Barbosa & R. Paixao - 2012 - European Psychologist 17:291-292.
    This study compares the performance, when identifying negative emotions on facial expression, of male offenders (n = 62) with a high level of psychopathy (n = 25) with other criminals with a low level of psychopathy (n = 37), as well as other ‘‘successful psychopaths’’(n = 12) and non-criminals with a low level of psychopathy (n = 39) in order to clarify the negative emotional processing of offenders and nonoffenders that are either high or low in psychopathy. The participants were (...)
