Aberrant neural processing of moral violations in criminal psychopaths

A defining characteristic of psychopathy is the willingness to intentionally commit moral transgressions against others without guilt or remorse. Despite this "moral insensitivity," the behavioral and neural correlates of moral decision-making in psychopathy have not been well studied. To address this issue, the authors used functional magnetic resonance imaging (fMRI) to record hemodynamic activity in 72 incarcerated male adults, stratified into psychopathic (n = 16) and nonpsychopathic (n = 16) groups based on scores from the Hare Psychopathy Checklist-Revised (R. D. Hare, 2003), while they made decisions regarding the severity of moral violations of pictures that did or did not depict moral situations. Consistent with hypotheses, an analysis of brain activity during the evaluation of pictures depicting moral violations in psychopaths versus nonpsychopaths showed atypical activity in several regions involved in moral decision-making. This included reduced moral/nonmoral picture distinctions in the ventromedial prefrontal cortex and anterior temporal cortex in psychopaths relative to nonpsychopaths. In a separate analysis, the association between severity of moral violation ratings and brain activity across participants was compared in psychopaths versus nonpsychopaths. Results revealed a positive association between amygdala activity and severity ratings that was greater in nonpsychopaths than psychopaths, and a negative association between posterior temporal activity and severity ratings that was greater in psychopaths than nonpsychopaths. These results reveal potential neural underpinnings of moral insensitivity in psychopathy and are discussed with reference to neurobiological models of morality and psychopathy.     

Searching for a Vulnerable Dark Triad: Comparing Factor 2 Psychopathy,Vulnerable Narcissism,and Borderline Personality Disorder

ABSTRACT Paulhus and Williams (2002) identified a “Dark Triad” comprising the following related personality styles: narcissism, psychopathy, and Machiavellianism. The heterogeneity found in narcissism and psychopathy raises the possibility of a second triad made up of emotional vulnerability and dark traits (i.e., the vulnerable dark triad; VDT). Along with vulnerable narcissism and Factor 2 psychopathy, the third member of the hypothesized VDT is borderline personality disorder (BPD). Using a sample of 361 undergraduates, we examine the relations between these constructs and their relations with criterion variables, including personality, environmental etiological factors (e.g., abuse), and current functioning (e.g., psychopathology, affect). The results suggest that the VDT constructs are significantly related to one another and manifest similar nomological networks, particularly vulnerable narcissism and BPD. Although the VDT members are related to negative emotionality and antagonistic interpersonal styles, they are also related to introversion and disinhibition. Ultimately, it seems there is a “dark continuum” of pathological personality traits that differ primarily in relation to negative and positive emotionality and disinhibition.     

Episcopal Measure of Faith Tradition: A Context-Specific Approach to Measuring Religiousness

Precise measurement of religiousness remains a vexing problem. In addition to relying almost exclusively on self-report, existing measures of religiousness pay little attention to the specific context of religious belief, and this may override distinctive norms of particular faith traditions and potentially confound the conclusions drawn from such research. To address these limitations, the authors describe a modified form of narrative content analysis that could eventually sort respondents into distinct theological traditions. A pilot test among Episcopalians demonstrates encouraging reliability (kappa 0.74, 95% LCI 0.47, P < 0.0002), and tests for convergent and discriminate validity suggest that the context of religious belief is both relevant and insufficiently assessed by the existing paradigm of religious measurements. If validated in a religiously diverse sample, this approach could be combined with existing, context-free measures of religiousness to generate more meaningful findings.     

Are secret relationships hot, then not? Romantic secrecy as a function of relationship duration

Are secret romances alluring or aversive? One theory suggests that romantic secrecy increases obsessive preoccupation with romantic partners and thereby enhances romantic relationships. Another theory suggests that romantic secrecy is burdensome and thereby undermines romantic relationships. We sought to rectify these conflicting perspectives by examining romantic secrecy and relationship duration using a large, Internet-based sample (N = 564). We predicted that romantic secrecy would have a positive influence in newer romantic relationships (obsessive preoccupation theory) and a negative influence in older romantic relationships (burden theory). In contrast, the obtained results indicate that romantic secrecy is a burden to both new and old romantic relationships.     

Gains in fluid intelligence after training non-verbal reasoning in 4-year-old children: a controlled, randomized study

Fluid intelligence (Gf) predicts performance on a wide range of cognitive activities, and children with impaired Gf often experience academic difficulties. Previous attempts to improve Gf have been hampered by poor control conditions and single outcome measures. It is thus still an open question whether Gf can be improved by training. This study included 4-year-old children (N = 101) who performed computerized training (15 min/day for 25 days) of either non-verbal reasoning, working memory, a combination of both, or a placebo version of the combined training. Compared to the placebo group, the non-verbal reasoning training group improved significantly on Gf when analysed as a latent variable of several reasoning tasks. Smaller gains on problem solving tests were seen in the combination training group. The group training working memory improved on measures of working memory, but not on problem solving tests. This study shows that it is possible to improve Gf with training, which could have implications for early interventions in children.     

Latina Adolescent Suicide Ideations and Attempts: Associations with Connectedness to Parents,Peers, and Teachers

Associations between suicidal behavior and social‐ecological variables were examined among 1,618 Latina high school students (mean age = 15) from the nationally representative Add Health sample (68% were U.S.‐born). Ideations were associated with having a suicidal friend, lower perceived father support, and overall parental caring. Attempts were associated with having a suicidal friend, and lower perceived teacher and parental support. Peer and mother relationship variables were not predictors of ideations or attempts. The protective role of father and teacher support has not previously been emphasized in the literature. Strengthening connections to parents and teachers may reduce suicidal behavior in adolescent Latinas.     

Videotape modeling for preschool children with low levels of social interaction and low peer involvement in play

This research evaluated a videotape modeling intervention for six preschool children who showed low levels of social involvement with peers in natural free-play settings. Observations across 14 weeks gave frequency and topographic data on social interactions and assessment of social involvement in play using the Parten Scale. Simultaneous observation of three children gave data on two comparison children for each target child. A multiple-baseline across-subjects design was used with two data analysis strategies. Averaged group data showed statistically significant increases in both interactions and social involvement in play. Visual analysis of the single-subject data, however, indicated no clear treatment outcome for two children, while four subjects showed a variable increase in social responding after viewing the modeling videotape. Session-by-session variability was a feature of the interaction rate measure for comparison children and for posttreatment phase data for target subjects.This research was supported by Grant No. 62-262-98 from the Mental Health Foundation of New Zealand and by University of Otago Research Committee Grant No. 37-877. Grateful acknowledgment is extended to Dan McKerracher and Ted Glynn for valued comments at various stages of the research. Appreciation is extended to the teachers and children of the Dunedin Free Kindergartens who participated in the study.
