An investigation of neuronal integrity in severe paediatric traumatic brain injury.

Magnetic Resonance Spectroscopy (MRS) and its association with neuropsychological functioning was examined in the chronic injury phase of paediatric traumatic brain injury (TBI). Fifteen children, aged 10-16 years, with severe TBIs were compared with 15 controls, matched for age and gender. The TBI group was found to have significantly lower levels of -acetyl aspartate (NAA) and Choline (Cho) in the right frontal lobe and generally displayed reduced performances on neuropsychological tests. A correlation between metabolites and reaction times was also obtained. Findings indicate a role of proton MRS as a measure of neuronal integrity following severe paediatric TBI and suggest a potential association of MRS with specific neuropsychological impairments.     

The effect of prosody on conceptual combination

Research into people's comprehension of novel noun-noun phrases has long neglected the possible influences of prosody during meaning construction. At the same time, work in conceptual combination has disagreed about whether different classes of interpretation emerge from single or multiple processes; for example, whether people use distinct mechanisms when they interpret octopus apartment as property-based (e.g., an apartment with eight rooms) or relation-based (e.g., an apartment where an octopus lives). In two studies, we manipulate the prosodic emphasis patterns of novel noun-noun combinations (placing stress on the modifier noun, the head noun, or dual stress on both nouns) and ask participants to generate an interpretation for the novel phrase. Results show that people are faster to generate property-based interpretations when dual emphasis stresses both nouns equally, with prosody having little effect on the speed of relation-based interpretations. These findings highlight a role for prosody during meaning construction and underline important differences between relation- and property-based interpretations that are difficult to reconcile with unitary process views of conceptual combination.     

A Multi‐Method,Multi‐Hazard Approach to Explore the Uniqueness of Terrorism Risk Perceptions and Worry1

Developing ways to manage terrorism effectively requires a better understanding of how the public perceives this threat. In the present study, Canadians' perceptions of terrorism risk and 4 other hazards were assessed using a word‐association technique and rating scales reflecting key cognitive dimensions of risk (threat, uncertainty, control) and worry reactions. Data were collected in a national telephone survey. Canadians perceived terrorism as posing a lower threat, as more uncertain, and as less controllable, compared to the other hazards. Positive associations of perceived threat and of perceived uncertainty with worry about terrorism were observed. However, perceived control was unexpectedly positively associated with worry about terrorism. The findings also suggest that additional social contextual factors should be examined in future research.     

Neuroticism and the Architecture of the Self: Exploring Neuroticism as a Moderator of the Impact of Ideal Self‐Discrepancies on Emotion

ABSTRACT Two studies examined the moderating role of neuroticism in discrepancy‐emotion relations. In Study 1, neuroticism, self‐discrepancies, and depression were measured. Multiple regression analyses revealed a significant interaction between neuroticism and ideal self‐discrepancies such that the magnitude of ideal self‐discrepancies was a stronger predictor of depression for people high in neuroticism than people low in neuroticism. Study 2 used an experimental paradigm to test the same hypothesis. Participants were randomly assigned to an ideal self‐discrepancy salience condition or a control condition in which ideal self‐discrepancies were not made salient. A significant interaction between self‐discrepancy condition and neuroticism emerged such that the ideal self‐discrepancy condition produced higher dejection‐related affect relative to the control condition for people high in neuroticism compared to people low in neuroticism.     

Should I trust you? Autistic traits predict reduced appearance‐based trust decisions

Facial impressions of trustworthiness guide social decisions in the general population, as shown by financial lending in economic Trust Games. As an exception, autistic boys fail to use facial impressions to guide trust decisions, despite forming typical facial trustworthiness impressions (Autism, 19, 2015a, 1002). Here, we tested whether this dissociation between forming and using facial impressions of trustworthiness extends to neurotypical men with high levels of autistic traits. Forty‐six Caucasian men completed a multi‐turn Trust Game, a facial trustworthiness impressions task, the Autism‐Spectrum Quotient, and two Theory of Mind tasks. As hypothesized, participants’ levels of autistic traits had no observed effect on the impressions formed, but negatively predicted the use of those impressions in trust decisions. Thus, the dissociation between forming and using facial impressions of trustworthiness extends to the broader autism phenotype. More broadly, our results identify autistic traits as an important source of individual variation in the use of facial impressions to guide behaviour. Interestingly, failure to use these impressions could potentially represent rational behaviour, given their limited validity.     

Criminal Minds: Narcissism Predicts Offending Behavior in a Non-Forensic Sample

Narcissism has been associated with various offending behaviors; however, the majority of research has concentrated on men using forensic samples. This study (n = 632) investigated narcissism and how it relates to offending behaviors, including both sexes. Significant differences were found when comparing the relationship between narcissism and offending behavior, demonstrating that narcissism influences offending behavior differently in the two sexes. These new findings contribute to the very little we know about narcissism in women, suggesting that both sexes should be included in future research on narcissism and offending.     

Sexual harassment expanded: An examination of the relationships among sexual harassment,sex discrimination,and aggression in the workplace

We hypothesized that sexual harassment is part of a broader behavioral family including aggression and discrimination. We examined whether the relationships between these types of mistreatment can be represented well by a general factor that relates to other workplace variables. Evidence from military datasets showed that sexual harassment, sex discrimination, and workplace aggression can be conceptualized as a more general factor that functioned well in an integrated model of sexual harassment and was experienced differently by men and women. Thus, there is utility in examining these types of mistreatment both together and independently, both for research and prevention purposes.     

Effects of subcultural differences on country and product evaluations

Most cross‐cultural studies on country of origin or product‐country image (PCI) effects have implicitly assumed that national markets are composed of homogeneous consumers. Although many investigations in this field are described as cross‐cultural, most are in fact cross‐national. The overarching hypothesis of the present research is that PCI effects may vary across subcultures within a country. The results indicate that subcultural differences exist in the evaluation of culturally affiliated countries and their products. Cognitive responses converged to show that consumers' perceived linkages significantly influence the weight given to the country of origin in product evaluations. Several implications for managers and academic researchers are discussed. Copyright © 2003 Henry Stewart Publications.     

“I know what a Muslim really is”: how political context predisposes the perceived need for an objective Muslim identity

This article explores the process by which Western Muslim young adults develop the need to experience an ‘objective’ religious identity. We interviewed 20 Western Muslim young adults born in Montreal, Berlin, and Copenhagen within the age range of 18–25, exploring their religious identity development. The interviews were semi-structured and open-ended. Thematic content analysis was used to explore patterns in their narratives. The participants disliked the perceived ethnocentric Muslim identity of their parents, which they sought to ‘purify’ for themselves from ‘cultural contamination’. There were two important elements underlying the process of religious identity objectification: experience of anti-Muslim political discourse and exposure to religious diversity in the aftermath of deterritorialisation.
