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.  相似文献

This study describes the development of a screening tool for gaming addiction in adolescents – the Gaming Addiction Identification Test (GAIT). Its development was based on the research literature on gaming and addiction. An expert panel comprising professional raters (= 7), experiential adolescent raters (= 10), and parent raters (= 10) estimated the content validity of each item (I‐CVI) as well as of the whole scale (S‐CVI/Ave), and participated in a cognitive interview about the GAIT scale. The mean scores for both I‐CVI and S‐CVI/Ave ranged between 0.97 and 0.99 compared with the lowest recommended I‐CVI value of 0.78 and the S‐CVI/Ave value of 0.90. There were no sex differences and no differences between expert groups regarding ratings in content validity. No differences in the overall evaluation of the scale emerged in the cognitive interviews. Our conclusions were that GAIT showed good content validity in capturing gaming addiction. The GAIT needs further investigation into its psychometric properties of construct validity (convergent and divergent validity) and criterion‐related validity, as well as its reliability in both clinical settings and in community settings with adolescents.  相似文献

The objective of the study is to evaluate the psychometric properties of the Gaming Addiction Identification Test (GAIT) and its parent version (GAIT‐P), in a representative community sample of adolescents and parents in Västmanland, Sweden. Self‐rated and parent‐rated gaming addictive symptoms identified by GAIT and GAIT‐P were analyzed for frequency of endorsement, internal consistency, concordance, factor structure, prevalence of Internet gaming disorder (IGD), concurrence with the Gaming Addiction Scale for Adolescents, 7‐item version (GAS) and the parent version of GAS (GAS‐P), and for sex differences. The 12‐month prevalence of IGD was found to be 1.3% with GAIT and 2.4% with GAIT‐P. Results also indicate promising psychometric results within this population, with high internal consistency, and high concurrent validity with GAS and GAS‐P. Concordance between adolescents and parents ratings was high, although moderate in girls. Although exploratory factor analysis indicated poor model fit, it also indicated unidimensionality and high factor loadings in all analyses. GAIT and GAIT‐P are suitable for continued use in measuring gaming addiction in adolescents, and, with the additional two items, they now cover all nine IGD criteria.  相似文献

Women athletes often struggle with attaining the muscular body needed to compete successfully, while at the same time negotiating expectations to conform to a lean and toned ideal. The purpose of this study was to explore women track and field athletes’ meanings of muscularity. Four adult and four adolescent women participated in focus groups and one-on-one interviews, exploring issues surrounding the body, including ideals and expectations. The participants also took photographs to represent their perceptions of their own muscularity. Four themes emerged: (a) many faces of muscularity, (b) a blurred line between appearance and performance, (c) a culture of comparison, and (d) a journey towards self-acceptance. Muscularity was identified as a complex and context specific experience, reflecting the multiple meanings of muscularity and the periods of struggle on the journey towards self-acceptance of the body.  相似文献

Cities invariably have “gray” areas where formal policing and regulatory reach is relatively ineffective. By focusing on individuals or groups traditional theories of deviance fail to account for community-level processes that create local alternative norms that contribute to behavior seen as deviant by outsiders. By combining theories of space with issues of identity construction and deviance, we analyze an inner-city neighborhood in Mexico City in terms of four factors: Structural Location, Material Form, Meaningfulness, and Organizational Integration. This creates a model for understanding forms of deviance that are rooted in community processes of resistance to the dominant normative system.  相似文献

In the history of ethics, it remains remains unclear how Christians of the Middle Ages came to see God‐given virtues as dispositions (habitus) created in the human soul. Patristic works could surely support other conceptions of the virtues given by grace. For example, one might argue that all such virtues are forms of charity, so that they must be affections of the soul, or that they consist in what the soul does, not anything the soul has. Scholars usually assume that the explanation lies in the impact of Aristotle's philosophy on medieval theology. This essay argues that the dispositional account of God‐given virtues was already entrenched by the end of the twelfth century and probably owes more to the influence of Augustine's treatise On the Good of Marriage.  相似文献

In 2 studies, the authors found that leader charisma was positively associated with followers' positive affect and negatively associated with followers' negative affect. The authors hypothesized that leaders' positive affect, positive expression, and aroused behavior will mediate these relationships. The results of their lab study suggest that leaders' positive expression and aroused behavior mediated these relationships. A field study showed that firefighters under the command of a charismatic officer were happier than those under the command of a non-charismatic officer and that these relationships were mediated by the leader's positive affect and a tendency to express positivity.  相似文献

Abstract concepts--rules that transcend training stimuli--have been argued to be unique to some species. Pigeons, a focus of much concept-learning research, were tested for learning a matching-to-sample abstract concept. Five pigeons were trained with three cartoon stimuli. Pigeons pecked a sample 10 times and then chose which of two simultaneously presented comparison stimuli matched the sample. After acquisition, abstract-concept learning was tested by presenting novel cartoons on 12 out of 96 trials for 4 consecutive sessions. A cycle of doubling the training set followed by retraining and novel-testing was repeated eight times, increasing the set size from 3 to 768 items. Transfer performance improved from chance (i.e., no abstract-concept learning) to a level equivalent to baseline performance (>80%) and was similar to an equivalent function for same/different abstract-concept learning. Analyses assessed the possibility that item-specific choice strategies accounted for acquisition and transfer performance. These analyses converged to rule out item-specific strategies at all but the smallest set-sizes (3-24 items). Ruling out these possibilities adds to the evidence that pigeons learned the relational abstract concept of matching-to-sample.  相似文献

This study investigated depressed mood post-acute coronary syndrome in an Australian sample using the Cardiac Depression Visual Analogue Scale (CD-VAS), which was developed to assess the depression-related symptoms of reduced pleasure, memory, activity, future pessimism, increased irritation and sleep problems. The Beck Depression Inventory-II, the Cardiac Depression Scale (CDS) and a demographic medical questionnaire were administered at 2 weeks post-ACS to an initial sample of 13 female and 45 male participants whose mean age was 59.16 (SD=11.13) years (range 38-79). Depressed and non-depressed participants, determined by the CDS, then kept a CD-VAS diary between 2 and 12 weeks. 32 participants kept the diary for the entire 10 weeks. Total CD-VAS scores remained elevated in the depressed group for the entire period. The groups differed on the Pleasure, Memory and Future items for a total of 6, 6 and 5 weeks, respectively, and differed on the Activity item only at 1, 3 and 5 weeks. No group differences were seen in the Irritation or Sleep items. Within the depressed group, the only CD-VAS items that differed from each other across time were Irritation and Activity. Further, the Sleep, Irritation and Activity items had a significant time effect. These results indicate that although overall depression, as measured by the CD-VAS, remained elevated in the depressed group, there were key differences in recovery rates of specific depression-related symptoms. These differences could be useful indicators in the treatment of depression post-ACS.  相似文献
