The five-factor narcissism inventory: a five-factor measure of narcissistic personality traits

This study provides convergent, discriminant, and incremental validity data for a new measure of narcissistic personality traits created from the perspective of the Five-factor model (FFM) of general personality structure. Fifteen scales were constructed as maladaptive variants of respective facets of the FFM (e.g., Reactive Anger as a narcissistic variant of angry hostility), with item selection made on the basis of a criterion-keying approach using results from 167 undergraduates. On the basis of data from 166 additional undergraduates, the convergent validity of these 15 scales was tested with respect to 8 established measures of narcissism (including measures of both grandiose and vulnerable narcissism) and the respective facets of the FFM. Discriminant validity was tested with respect to facets from other FFM domains. Incremental validity was tested with respect to the ability of the FFM narcissism trait scales to account for variance in 2 alternative measures of narcissism, after variance accounted for by respective NEO PI-R facet scales and other established measures of narcissism were first removed. The findings support the validity of these new scales as measures of narcissistic personality traits and as maladaptive variants of the FFM.     

Help Me Play! Parental Behaviors,Child Temperament,and Preschool Peer Play

Social competence is a critical developmental milestone for preschoolers. Because play is the primary activity through which preschoolers interact socially with peers, it serves as an excellent indicator of social competence. The development of social competence in preschoolers is complex and multifaceted. In order to capture this complexity, we used Belsky’s differential susceptibility hypothesis as a framework for examining the contributions of child temperament and parenting styles in the prediction of peer interactive play behaviors. Using parent ratings of a sample of 44 preschool-age children, we hypothesized that child temperament (specifically, reactivity and regulation) acts as a susceptibility factor in the relationship between parenting styles (authoritarian and authoritative) and child peer play behaviors (disruptive and interactive). Our findings indicated that child reactivity moderated the relationship between authoritarian parenting style and both play outcomes, suggesting that reactivity serves as a potential susceptibility factor. More specifically, children with high reactivity who had more authoritarian parents demonstrated higher levels of disruptive play and lower levels of interactive play. Regulation did not act as a susceptibility factor in our sample. Findings are discussed in terms of implications for practice and in terms of an approach that considers temperament (specifically reactivity) and parenting behaviors in preschool assessment and intervention efforts. Additionally, we discuss how our findings partially support the differential susceptibility hypothesis.     

Moral reasoning and moral orientation of U.S. and Turkish university students

Participants from an individualistic society (U.S.A.) were compared with participants from a collectivistic society (Turkey) in terms of moral reasoning and orientation (justice and care). A total of 396 undergraduates (203 U.S. students, 193 Turkish students) between the ages of 18 and 46 years were administered the original version of the Defining Issues Test and the Measure of Moral Orientation. Turkish participants received higher mean principled scores than did the U.S. participants, and female participants received higher mean principled scores than did male participants. Turkish participants also scored significantly higher on the justice and care orientations than U.S. participants, and female participants scored significantly higher on the justice and care orientations than male participants.     

The contribution of novel brain imaging techniques to understanding the neurobiology of mental retardation and developmental disabilities

Studying the biological mechanisms underlying mental retardation and developmental disabilities (MR/DD) is a very complex task. This is due to the wide heterogeneity of etiologies and pathways that lead to MR/DD. Breakthroughs in genetics and molecular biology and the development of sophisticated brain imaging techniques during the last decades have facilitated the emergence of a field called Behavioral Neurogenetics. Behavioral Neurogenetics focuses on studying genetic diseases with known etiologies that are manifested by unique cognitive and behavioral phenotypes. In this review, we describe the principles of magnetic resonance imaging (MRI) techniques, including structural MRI, functional MRI, and diffusion tensor imaging (DTI), and how they are implemented in the study of Williams (WS), velocardiofacial (VCFS), and fragile X (FXS) syndromes. From WS we learn that dorsal stream abnormalities can be associated with visuospatial deficits; VCFS is a model for exploring the molecular and brain pathways that lead to psychiatric disorders for which subjects with MR/DD are at increased risk; and finally, findings from multimodal imaging techniques show that aberrant frontal-striatal connections are implicated in the executive function and attentional deficits of subjects with FXS. By deciphering the molecular pathways and brain structure and function associated with cognitive deficits, we will gain a better understanding of the pathophysiology of MR/DD, which will eventually make possible more specific treatments for this population.     

Separate visual representations in the planning and control of action

Evidence for a dichotomy between the planning of an action and its on-line control in humans is reviewed. This evidence suggests that planning and control each serve a specialized purpose utilizing distinct visual representations. Evidence from behavioral studies suggests that planning is influenced by a large array of visual and cognitive information, whereas control is influenced solely by the spatial characteristics of the target, including such things as its size, shape, orientation, and so forth. Evidence from brain imaging and neuropsychology suggests that planning and control are subserved by separate visual centers in the posterior parietal lobes, each constituting part of a larger network for planning and control. Planning appears to rely on phylogenetically newer regions in the inferior parietal lobe, along with the frontal lobes and basal ganglia, whereas control appears to rely on older regions in the superior parietal lobe, along with the cerebellum.     

Maternal stress in pregnancy and its effect on the human foetus: an overview of research findings

There is evidence from human studies that anxiety or stress during pregnancy can affect birth outcome, causing babies to be born earlier and possibly smaller for gestational age. There is also some suggestive evidence for longer-term behavioural problems. Animal studies indicate that antenatal stress does have a long-term effect on the behaviour of the offspring, including a hyper-responsive hypothalamo-pituitary -adrenal axis. The human foetus can mount an independent stress response from mid-gestation. Two possible mechanisms have been demonstrated by which maternal stress or anxiety may affect the human foetus, the passage of cortisol across the placenta, and an impairment of blood flow through the maternal uterine arteries.     

Teaching ethics on rounds: The ethicist as teacher,consultant, and decision-maker

This paper explores the relationship between teaching and consulting in clinical ethics teaching and the role of the ethics teacher in clinical decision-making. Three roles of the clinical ethics teacher are discussed and illustrated with examples from the authors' experience. Two models of the ethics consultant are contrasted, with an argument presented for the ethics consultant as decision facilitator. A concluding section points to some of the challenges of clinical ethics teaching.
