Maria Isabel Gonzalez-Tapia, Ingrid Obsuth, Rachel Heeds
Public perception, fueled not only by popular and news media but also by expert claims that psychopaths are archetypes of evil: incorrigible, remorseless, cold-blooded criminals, whose crimes manifest in the most extreme levels of violence. But is there empirical evidence that psychopaths truly are what they are portrayed to be? If so, should the law respond, and adjust its treatment of psychopaths in court - permitting psychopathy to be admitted under an insanity defense and/or resulting in mitigation? In this paper, we demonstrate that fundamental questions from the law to science remain unanswered and must be addressed before any alternative treatment of psychopathy can be considered...

The present study examined the association between psychopathic traits and functional connectivity in 177 incarcerated male adolescents. We hypothesized that psychopathic symptoms would be associated with functional connectivity within networks encompassing limbic and paralimbic regions, such as the default mode (DMN), salience networks (SN), and executive control network (ECN). The present sample was drawn from the Southwest Advanced Neuroimaging Cohort, Youth sample, and from research at a youth detention facility in Wisconsin...

Researchers have consistently found a relationship between psychopathy and the use of sexual coercion in samples of males with and without previous sexual arrests (Abbey, Jacques-Tiura, & LeBreton, 2011; Hare, 1991; Hersh & Gray-Little, 1998; Seto & Lalumiere, 2000). Although there is growing recognition that females also engage in sexually coercive behavior, current understanding of female coercion is limited (Bouffard, Bouffard, & Miller, 2015; Cortoni, Hanson, & Coache, 2010; Muñoz, Khan, & Cordwell, 2011)...

Few studies have examined the extent to which psychopathic traits relate to the commission of mild to moderate acts of deviance, such as vandalism and minor traffic violations. Given that psychopathy is now studied in community populations, the relationship between psychopathic traits and less severe deviant behaviors, which are more normative among noninstitutionalized samples, warrants investigation. The current study examined the relationships between the triarchic model of psychopathy (Patrick, Fowles & Krueger, 2009) and seven forms of deviant behavior (drug use, alcohol use, theft, vandalism, school misconduct, assault, and general deviance) in a nationally representative sample...

The Youth Psychopathic Traits Inventory (YPI) is widely used in research, but there currently exist no means to identify potentially invalid protocols resulting from careless or random responding. We describe the development of an inconsistent responding scale for the YPI using three archival samples of youths, including two from the United States (juvenile justice and middle school) and one from Germany (vocational training school). We first identified pairs of correlated YPI items and then created a total score based on the sum of the absolute value of the differences for each item pair...

The current study undertook analyses of genealogical data from a sample of 178 socially-housed chimpanzees (Pan troglodytes) with well-documented pedigrees, to clarify the etiologic bases of triarchic psychopathy dimensions and the influence of early social rearing experiences. Whereas biometric analyses for the full sample indicated significant heritability for the boldness dimension of psychopathy only, heritability estimates varied by early rearing, with all three triarchic dimensions showing significant heritabilities among mother-reared but not nursery-reared apes...

BACKGROUND: There have been no systematic reviews that investigated the heritability of the two-factor model of psychopathy: interpersonal-affective and behavioral. Our review aimed, first, to examine the heritability of general psychopathic traits and, second, if genetic influences were suggested, to determine the heritability of various traits related to the interpersonal-affective and behavioral factors of psychopathy. METHOD: A systematic literature search was conducted using articles from the PsycINFO, Embase, Global Health, Medline, PubMed, Web of Science, and Scopus databases (January of 1980 to December of 2015) in order to identify eligible literature that reported on the heritability of psychopathy-related traits...

The current study investigated the relationship between psychopathy and two concepts that hold a central position in conceptualizations of this disorder, being guilt and dominance. Both constructs were measured using explicit measures (i.e., self-report), as well as indirect assessment (i.e., the Single Category Implicit Association Test; Sc-IAT). Our sample consisted of 43 psychopathic offenders, 42 nonpsychopathic offenders, and 26 nonoffender controls. Although no overall group differences emerged, the lifestyle/antisocial traits of psychopathy (Factor 2) predicted reduced self-reported guilt on a dimensional level...

This study investigated how well components of the psychopathy trait are measured among college students with the Levenson Self-Report Psychopathy Scale (LSRP), the Personality Assessment Inventory-Antisocial Features Scale (PAI ANT), the Psychopathic Personality Inventory-Short Form (PPI-SF), and the Self-Report Psychopathy Scale-II (SRP-II). Using Samejima (1969)'s graded response model (GRM), the subscales were found to vary in their ability to measure the corresponding latent traits. The LSRP primary psychopathy factor is more precise in measuring the latent trait than the secondary psychopathy factor...

The current study employed both latent variable- and person-centered approaches to examine psychopathic traits in a large sample of sex offenders (N = 958). The offenders, who had committed a range of sexual crimes, had been assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four-factor model of psychopathy (Hare, 2003; Neumann, Hare, & Newman, 2007) provided good representation of the dimensional nature of psychopathic traits across the sample of offenders, and that the PCL-R factors significantly predicted sexual crimes...

Emotional mimicry and empathy are mechanisms underlying social interaction. Benzodiazepines have been proposed to inhibit empathy and promote antisocial behaviour. First, we aimed to investigate the effects of oxazepam on emotional mimicry and empathy for pain, and second, we aimed to investigate the association of personality traits to emotional mimicry and empathy. Participants (n=76) were randomized to 25 mg oxazepam or placebo. Emotional mimicry was examined using video clips with emotional expressions...

Psychopathy is a personality disorder characterized by callous lack of empathy, impulsive antisocial behavior, and criminal recidivism. Studies of brain structure and function in psychopathy have frequently identified abnormalities in the prefrontal cortex. However, findings have not yet converged to yield a clear relationship between specific subregions of prefrontal cortex and particular psychopathic traits. We performed a multimodal neuroimaging study of prefrontal cortex volume and functional connectivity in psychopathy, using a sample of adult male prison inmates (N=124)...

K. Birnbaum's concept of psychopathic personalities is analyzed. K. Birnbaum was one of the first psychiatrists who had suggested the differentiation of psychopathic personalities according to the degree of social damage they caused. As personality abnormality classification according to one prominent trait that led to hiding signs of the general psychopathic constitution in clinical description, as the reliance on erroneous genetic theories with idealization of social behavior norms led to the antihuman medical recommendations...

The current study examined the reliability and validity of the Youth Psychopathic Traits Inventory-Short Version (YPI-S) in two different samples of at-risk adolescents enrolled in a residential program ( n = 160) and at a detention facility ( n = 60) in the United States. YPI-S scores displayed adequate internal consistency and were moderately associated with concurrent scales on other self-report psychopathy measures and externalizing behaviors. YPI-S scores were moderately related to interviewer-ratings of the construct using the four-factor model of the Psychopathy Checklist: Youth Version...

Elvio Baccarini, Luca Malatesti
We argue that the mandatory moral bioenhancement of psychopaths is justified as a prescription of social morality. Moral bioenhancement is legitimate when it is justified on the basis of the reasons of the recipients. Psychopaths expect and prefer that the agents with whom they interact do not have certain psychopathic traits. Particularly, they have reasons to require the moral bioenhancement of psychopaths with whom they must cooperate. By adopting a public reason and a Kantian argument, we conclude that we can justify to a psychopath being the recipient of mandatory moral bioenhancement because he has a reason to require the application of this prescription to other psychopaths...

Neuroscience has identified brain structures and functions that correlate with psychopathic tendencies. Since psychopathic traits can be traced back to physical neural attributes, it has been argued that psychopaths are not truly responsible for their actions and therefore should not be blamed for their psychopathic behaviors. This experimental research aims to evaluate what effect communicating this theory of psychopathy has on the moral behavior of lay people. If psychopathy is blamed on the brain, people may feel less morally responsible for their own psychopathic tendencies and therefore may be more likely to display those tendencies...

In 2009, Gao and Raine's meta-analysis analysed P3 modulation over the antisocial spectrum. However, some questions remained open regarding the P3 modulation patterns across impulsive and violent manifestations of antisocial behaviour, phenotypic components of psychopathy, and P3 components. A systematic review of 36 studies was conducted (N=3514) to extend previous results and to address these unresolved questions. A clear link between decreased P3 amplitude and antisocial behaviour was found. In psychopathy, dimensional approaches become more informative than taxonomic models...

BACKGROUND AND OBJECTIVES: Driving while intoxicated (DWI) represents an area of grave concern in China, yet little research has focused on it or on the personality traits and psychiatric disorders among these drivers. METHODS: We enrolled 325 of 382 residents charged with DWI in a compulsory detention center in Beijing, China. And 351 male drivers who had never had any alcohol arrests as control participants. All were screened for Axis I disorders using the Chinese version of the Structured Clinical Interview for the Diagnostic Statistical Manual of Mental Disorders IV-TR (SCID), the Minnesota Multiphasic Personality Inventory (MMPI-2), and the Sixteen Personality Factor Questionnaire (16PF)...

Psychopathic traits are a manifestation of a personality pathology that comprises a core affective-interpersonal dysfunction (callous-unemotional traits) and an impulsive-antisocial behavioral component. Of particular importance, psychopathic traits are associated with the perpetration of some of the most severe acts of violence, and they appear to indicate a subset of youth at risk for earlier onset, greater frequency, and persistence of violent offending. Although these youth represent a minority of the population, they commit a significant proportion of the violence in the general community...
