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 N-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. 相似文献

Detecting and learning the location of unpleasant or pleasant scenarios, or spatial affect learning, is an essential skill that safeguards well-being (Crawford & Cacioppo, 2002). Potentially altered by psychiatric illness, this skill has yet to be measured in adults with and without major depressive disorder (MDD) and anxiety disorders (AD). This study enrolled 199 adults diagnosed with MDD and AD (n=53), MDD (n=47), AD (n=54), and no disorders (n=45). Measures included clinical interviews, self-reports, and a validated spatial affect task using affective pictures (IAPS; Lang, Bradley, & Cuthbert, 2005). Participants with MDD showed impaired spatial affect learning of negative stimuli and irrelevant learning of pleasant pictures compared with non-depressed adults. Adults with MDD may use a “GOOD is UP” heuristic reflected by their impaired learning of the opposite correlation (i.e., “BAD is UP”) and performance in the pleasant version of the task. 相似文献

The present study was conducted to examine the role of friends in women’s body image concerns. Self and peer reports were completed by a convenience sample of 75 pairs of same gender female friends (N?=?150) from a small undergraduate university in Eastern Canada. In a conceptual replication of previous research, we first showed that self-reports of perceived pressure to be thin significantly predicted women’s own body image concerns when controlling for body mass. Of interest was the finding that body-related talk between friends that focused on exercise significantly predicted less body dissatisfaction. Additionally, by examining the relationships between self and peer reports, we showed that women’s perceptions of their friends’ body image concerns aligned to both self-reports and to friends’ actual reports suggesting that women likely projected their own self-views when perceiving friends. Moreover, using multiple regression analyses, we demonstrated that perceptions of friends, and not friends’ actual reports, predicted own body concerns. Besides the suggestions for future research stemming from limitations of the present study, we suggest that researchers interested in similarities between friends on women’s body image concerns include both perceptions of peers and actual peer reports. 相似文献

Anger and its treatment is a major issue in a variety of contexts, although it remains underexplored. In this study 10 young people completed semi-structured interviews and repertory grids. Interpretative phenomenological analysis (IPA) and repertory grid analysis were conducted. Findings consistently indicated that anger is a more similar than different experience for participants within dialectical processes involving disempowering, empowering, and disengaging narratives that can be affected by positive personal and interpersonal phenomena and socially driven beliefs. Clinical and research implications are discussed. 相似文献

Much evidence has suggested that people conceive of time as flowing directionally in transverse space (e.g., from left to right for English speakers). However, this phenomenon has never been tested in a fully nonlinguistic paradigm where neither stimuli nor task use linguistic labels, which raises the possibility that time is directional only when reading/writing direction has been evoked. In the present study, English-speaking participants viewed a video where an actor sang a note while gesturing and reproduced the duration of the sung note by pressing a button. Results showed that the perceived duration of the note was increased by a long-distance gesture, relative to a short-distance gesture. This effect was equally strong for gestures moving from left to right and from right to left and was not dependent on gestures depicting movement through space; a weaker version of the effect emerged with static gestures depicting spatial distance. Since both our gesture stimuli and temporal reproduction task were nonlinguistic, we conclude that the spatial representation of time is nondirectional: Movement contributes, but is not necessary, to the representation of temporal information in a transverse timeline. 相似文献

The concept of dual-use encapsulates the potential for well-intentioned, beneficial scientific research to also be misused by a third party for malicious ends. The concept of dual-use challenges scientists to look beyond the immediate outcomes of their research and to develop an awareness of possible future (mis)uses of scientific research. Since 2001 much attention has been paid to the possible need to regulate the dual-use potential of the life sciences. Regulation initiatives fall under two broad categories—those that develop the ethical education of scientists and foster an awareness and responsibility of dual-use issues, and those which assess the regulation of information being generated by current research. Both types of initiatives are premised on a cautious, risk-adverse philosophy which advocates careful examination of all future endpoints of research endeavors. This caution advocated within initiatives such as pre-publication review of journal articles contrasts to the obligation to share underpinning data sharing discussions. As the dual-use debate has yet to make a significant impact on data sharing discussions (and vice versa) it is possible that these two areas of knowledge control may present areas of ethical conflict for scientists, and thus need to be more closely examined. This paper examines the tension between the obligation to share exemplified by data sharing principles and the concerns raised by the risk-cautious culture of the dual-use debates. The paper concludes by reflecting on the issues of responsibility as raised by dual-use as relating to data sharing, such as the chain of custody for shared data. 相似文献

This review systematically examines the empirical literature to determine the support available for seven proposed Implicit Theories (ITs) held by heterosexual male and female perpetrators of intimate partner violence. Based on previous literature that has hypothesized and identified ITs in intimate partner violence (IPV) and other types of offenders, we suggest six potential ITs likely to be held by men and women: “Opposite sex is dangerous”, “Relationship entitlement”, “General entitlement”, “Normalization of relationship violence”, “Normalization of violence”, and “It's not my fault”. We suggest one extra IT held by male perpetrators: “I am the man”. Electronic databases were searched from 1980 onwards, using predetermined relevant key words, to identify IPV research that has examined factors associated with each of the proposed seven ITs. Support was found for the existence of all seven ITs, but it differed in terms of strength, mainly due to the dearth or poor quality of empirical research on specific areas, especially in female perpetrated IPV. Implications for treatment and future directions are discussed. 相似文献

This research set out to establish which of four statements reflecting Christian commitment ('usually go to church on Sunday', 'have given my life to Jesus', 'read the Bible every week' and 'pray most days') were the most important predictors of never having smoked, drunk alcohol or tried drugs amongst a group of church affiliated young people. A self-report questionnaire was completed by 7661 participants aged 12-30. Agreement with the Christian commitment statements was generally associated with a lesser likelihood of having smoked, drunk alcohol or tried drugs, though different factors were found to be important in predicting lifetime substance use in the two age groups surveyed (12-16 years and age 17-30). Church attendance was the only factor which predicted each behaviour for the younger age group (12-16 years), but for older participants (age 17-30), statements suggesting a greater level of commitment were most important ('have given my life to Jesus', 'read the Bible every week'). The findings suggest that for church affiliated young people it is initially the socialization of religion that acts as a prohibitor against substance use, though, as age increases, a greater internalization of Christian commitment becomes more important. 相似文献

ABSTRACT Standard measures of phonemic and semantic fluency, as well as fluency measures that impose additional demands upon set-switching were administered to younger and older adults. No age effect was found for total output on semantic fluency, while older participants generated significantly more responses relative to their younger counterparts on the phonemic measure. However, older adults made significantly more perseverative errors on both these measures. For tests of alternating fluency, only where participants were required to switch between two semantic dimensions, was an age deficit observed. Although the correlation between phonemic repetitions and age remained significant when performance on the Digit Symbol Test or a measure of fluid intelligence was partialled out, age effects for semantic repetitions and semantic alternating fluency were substantially reduced. The age benefit for number of correct responses upon phonemic fluency was significantly attenuated when a measure of crystallized intelligence was entered as a control variable. The theoretical and practical implications of these results are discussed. 相似文献

Few studies on creativity have focused on creativity development in various grade levels for high-achieving students. The purpose of this study was to explore the developmental trajectories of creative ability for high-achieving students. The participants constituted a national representative sample of 982 male (N = 506) and female (484) students from grades 1 to 10 in five governorates in Oman (Muscat, South-Al Batinah, South- Al Sharqia, Dhofar, and Al Dhakilia). The students completed two subtests of the Profile of Creative Abilities (PCA), a measure of creative potential, namely drawings and categories. There was an evidence of a developmental trend of creativity across grade levels. The Multi-variate analysis of variance (MANOVA) showed that the main effect of grade was statistically significant for the drawings subtest. Also, the main effect of gender was also statistically significant for the drawings subtest. The main effect of interaction (gender X grade) was not significant. Overall, females’ creative performance was significantly better than males’ in the Creativity Index score. The results of the study are discussed in the light of existing literature about developmental trends and gender differences in creative thinking. 相似文献
