Psychopathy is a personality disorder that includes interpersonal-affective and antisocial deviance features. The Psychopathic Personality Inventory (PPI) contains two underlying factors (fearless dominance and impulsive antisociality) that may differentially tap these two sets of features. In a mixed-gender sample of undergraduates and prisoners, we found that PPI fearless dominance was related to low Behavioral Inhibition System activity, high Behavioral Activation System (BAS) activity, expert prototype psychopathy scores, and primary psychopathy. Impulsive antisociality was related to high BAS activity and all psychopathy measures. High Extraversion and Openness and low Neuroticism and Agreeableness predicted fearless dominance, whereas high Neuroticism and low Agreeableness and Conscientiousness predicted impulsive antisociality. Although low levels of Agreeableness predicted both PPI factors, their differential relations with other five-factor model traits highlight differences in the way psychopathy manifests itself. Consistent with movements toward assessing personality disorder using the five-factor model, the authors report regression-based equations for the clinical assessment of these psychopathy dimensions using the NEO Personality Inventory-Revised (NEO-PI-R). 相似文献

Nightmares, Bad Dreams, and Emotion Dysregulation: A Review and New Neurocognitive Model of Dreaming
ABSTRACT— Nightmares—vivid, emotionally dysphoric dreams—are quite common and are associated with a broad range of psychiatric conditions. However, the origin of such dreams remains largely unexplained, and there have been no attempts to reconcile repetitive traumatic nightmares with nontraumatic nightmares, dysphoric dreams that do not awaken the dreamer, or with more normative dreams. Based on recent research in cognitive neuroscience, sleep physiology, fear conditioning, and emotional-memory regulation, we propose a multilevel neurocognitive model that unites waking and sleeping as a conceptual framework for understanding a wide spectrum of disturbed dreaming. We propose that normal dreaming serves a fear-extinction function and that nightmares reflect failures in emotion regulation. We further suggest that nightmares occur as a result of two processes that we term affect load—a consequence of daily variations in emotional pressures—and affect distress—a disposition to experience events with high levels of negative emotional reactivity. 相似文献

Parfit argues that a form of rule consequentialism can be derived from the most plausible formulation of the fundamental principle of Kantian ethics. And so he concludes that Kantians should be consequentialists. I argue that we have good reason to reject two of the auxiliary premises that figure in Parfit's derivation of rule consequentialism from Kantianism. 1 相似文献

We investigated the effects of increased inter-hemispheric interaction (IHI) on five creativity dimensions (appropriateness, detail, categorical distinctiveness, fluency, and originality) of the Alternate Uses Task. Two methods were used to indicate degree of IHI. Trait IHI was indicated by individual differences in handedness, mixed-handers showing greater IHI than strong-handers. State IHI was directly manipulated by central (control group) and bilateral viewing conditions of a 30 s eye movement task (EM). Results indicate significantly higher creativity for mixed-handers, as compared to strong-handers, for all five sub-scores separately and linearly combined. Bilateral EM increased originality and categorical distinctiveness (i.e., flexibility) of strong-handers, but had no effect on mixed-handers. Strong-handers in the bilateral EM group were not different from mixed-handers. Additionally, the bilateral EM effect on strong-handers had different durations for originality (up to 7–9 min) and categorical distinctiveness (up to 3 min). The results suggest that greater IHI can facilitate creativity of strong-handers, but that the characteristically higher IHI of mixed-handers was unaffected by the bilateral EM manipulation. 相似文献

A study was conducted to determine whether academic performance could be predicted on the bases of the constructs need for cognition (NFC) and academic self‐efficacy. Two hypotheses were generated: Positive correlations will be found between academic self‐efficacy, NFC, and grade point average (GPA); and efficacy and NFC will serve as significant predictors of GPA. The path mediation technique recommended by Baron & Kenny (1986) for testing mediated relationships was also performed in order to assess the causal direction of the NFC and academic self‐efficacy variables. Participants were 138 undergraduate students. The first hypothesis was generally supported in that significant correlations were found between NFC, efficacy beliefs, and GPA. In support of the second hypothesis, path analysis revealed that NFC and academic self‐efficacy were significant predictors of GPA. Furthermore, the NFC‐GPA relationship was shown to be mediated by efficacy beliefs. 相似文献

Clinical research is now a global enterprise. However, research ethics capacity has lagged behind the growth and expansion
of clinical research in low and middle income countries. To address this mismatch, the Fogarty International Center of the
National Institutes of Health has created a program to fund education in research ethics. This series of articles describes
the experiences of graduates from 5 nations of the University of Toronto’s Joint Centre for Bioethics International Masters
of Health Science Program. The program has graduated 32 students to return to their institutions to build research ethics
capacity. 相似文献

Unlike the aphasic syndromes, the organization of affective prosody in brain has remained controversial because affective-prosodic deficits may occur after left or right brain damage. However, different patterns of deficits are observed following left and right brain damage that suggest affective prosody is a dominant and lateralized function of the right hemisphere. Using the Aprosodia Battery, which was developed to differentiate left and right hemisphere patterns of affective-prosodic deficits, functional-anatomic evidence is presented in patients with focal ischemic strokes to support the concepts that (1) affective prosody is a dominant and lateralized function of the right hemisphere, (2) the intrahemispheric organization of affective prosody in the right hemisphere, with the partial exception of Repetition, is analogous to the organization of propositional language in the left hemisphere and (3) the aprosodic syndromes are cortically based as part of evolutionary adaptations underlying human language and communication. 相似文献

A randomised, double-blind, placebo-controlled, between subjects study design (N=37) was used to investigate the effects of dexamphetamine on explicit new name learning. Participants ingested 10mg of dexamphetamine or placebo daily over 5 consecutive mornings before learning new names for 50 familiar objects plus fillers. The dexamphetamine group recognised and recalled the new names more accurately than the placebo group over the 5 days and 1 month later. Word learning success was not associated with baseline neuropsychological performance, mood, cardiovascular arousal, or sustained attention. These results may have implications for the pharmacological treatment of acquired naming difficulties. 相似文献

Groups around the world are seeking reparations for historical harms. In three studies, the authors examined if people are more inclined to support a historical victim group if the group continues to suffer today because of an earlier harm. In Study 1, participants perceived greater victim suffering when the harm was recent and the degree of perceived suffering positively related to victim group support. In Studies 2 and 3, the authors manipulated continued victim suffering and the feasibility of material reparations. Both variables affected victim group support, but experienced sympathy and injustice judgments mediated their effects. Suffering victims elicited more compassion when reparations seemed feasible but were treated the same as nonsuffering victims when reparations seemed unfeasible. Suffering victims were also treated equally irrespective of feasibility of reparations, whereas nonsuffering victims were treated significantly less favorably when reparations seemed feasible, versus unfeasible. 相似文献
