This study examined gender differences in cognitive and emotional status after traumatic brain injury (TBI) among 262 men and 140 women with TBI referred for neuropsychological evaluations. In this cross-sectional study, cognition was measured in terms of both absolute level of functioning (i.e., raw/standard scores) and estimated decline from premorbid levels expressed as z-deficit scores in the following domains: intelligence [Wechsler Adult Intelligence Scale—Revised (WAIS-R)], memory and attention [Wechsler Memory Scale—Revised (WMS-R)], processing speed (Trails A), and cognitive flexibility (Trails B). Emotional functioning was measured in terms of depression (Beck Depression Inventory) and general emotional distress (Brief Symptom Inventory). Kruskal–Wallis nonparametric one-way ANOVAs indicated that women and men differed significantly on 2 of 8 raw/standard cognitive scores [men demonstrated lower WMS-R General Memory (p < .05) and Trails B scores (p < .0001) and 4 of 8 relative decline scores [women demonstrated more estimated change in VIQ (Verbal IQ) [p < .0001], FSIQ (Full Scale IQ) [p < .01], and Attention (p < .01)]; men demonstrated greater estimated z-decline scores on Trails B (p < .01)]. Women reported significantly higher levels of depression (p < .01), but men endorsed significantly greater general psychological distress (p < .05). Research and assessment recommendations are suggested. 相似文献

Although mild head injury is the most prevalent type of head injury in children and adolescents, only a relatively small number of studies on this kind of head injury have been reported. This article summarizes a review of studies examining cognitive, academic, and psychosocial outcomes in children who sustained mild head injuries. Despite earlier claims of mild head injury being a "silent epidemic," the studies, which were published from 1970 to 1998, provide no compelling evidence to support this view. 相似文献

Ethics and Nanotechnology: Views of Nanotechnology Researchers 总被引:1,自引:1,他引:0
Robert McGinn 《Nanoethics》2008,2(2):101-131
A study was conducted of nanotechnology (NT) researchers’ views about ethics in relation to their work. By means of a purpose-built
questionnaire, made available on the Internet, the study probed NT researchers’ general attitudes toward and beliefs about
ethics in relation to NT, as well as their views about specific NT-related ethical issues. The questionnaire attracted 1,037
respondents from 13 U.S. university-based NT research facilities. Responses to key questionnaire items are summarized and
noteworthy findings presented. For most respondents, the ethical responsibilities of NT researchers are not limited to those
related to safety and integrity in the laboratory. Most believe that NT researchers also have specific ethical responsibilities
to the society in which their research is done and likely to be applied. NT appears to be one of the first areas of contemporary
technoscientific activity in which a long-standing belief is being seriously challenged: the belief that society is solely
responsible for what happens when a researcher’s work, viewed as neutral and merely enabling, is applied in a particular social
context. Survey data reveal that most respondents strongly disagree with that paradigmatic belief. Finally, an index gauging
NT researcher sensitivity to ethics and ethical issues related to NT was constructed. A substantial majority of respondents
exhibited medium or high levels of sensitivity to ethics in relation to NT. Although most respondents view themselves as not
particularly well informed about ethics in relation to NT, a substantial majority are aware of and receptive to ethical issues
related to their work, and believe that these issues merit consideration by society and study by current and future NT practitioners.

Sex differences in mathematical performance have frequently been examined over the last decades indicating an advantage for males especially when numerical problems cannot be solved by (classroom‐)learnt strategies and/or estimation. Even in basic numerical tasks such as number line estimation, males were found to outperform females – with sex differences argued to emerge from different solution strategies applied by males and females. We evaluated the latter using two versions of the number line estimation task: a bounded and an unbounded task version. Assuming that women tend more strongly to apply known procedures, we expected them to be at a particular disadvantage in the unbounded number line estimation task, which is less prone to be solved by specific strategies such as proportion judgement but requires numerical estimation. Results confirmed more pronounced sex differences for unbounded number line estimation with males performing significantly more accurately in this task version. This further adds to recent evidence suggesting that estimation performance in the bounded task version may reflect solution strategies rather than numerical estimation. Additionally, it indicates that sex differences regarding the spatial representation of number magnitude may not be universal, but associated with spatial–numerical estimations in particular. 相似文献

We proposed that nostalgia, by virtue of its sociality, can be an indirect strategy to counteract relational deficiencies stemming from group‐based exclusion. We instructed Greek participants to recall an event in which they experienced exclusion on the basis of their nationality versus a control event. We anticipated that participants would react to group‐based exclusion with increased nostalgia. Specifically, because low attachment‐related avoidance facilitates proximity‐seeking in response to distress, we hypothesized that group‐based exclusion would increase nostalgia (a form of proximity‐seeking) more strongly when avoidance is low. Results supported this moderation hypothesis. In turn, increased nostalgia in response to group‐based exclusion predicted stronger ingroup identification. For low‐avoidants, then, group‐based exclusion fortified ingroup identification via increased nostalgia (moderated mediation). 相似文献

Against the background of the embodied cognition approach this experiment investigated the influence of motor expertise on object-based vs. egocentric transformations in a chronometric mental rotation (MR) task using images of either the own or another person’s body as stimulus material. The present study aimed to clarify two issues: (1) whether stimulus size (life size vs. small) is able to induce embodiment effects and (2) which role self-awareness processes play when using stimuli of the own body. The same design was conducted twice using both small stimuli (Study 1) and life-size human figures (Study 2). Using life-sized figures in Study 2 resulted in an explicit advantage of self-related stimuli and improved performance for motor experts compared to non-motor experts in both object-based and egocentric transformations. In conclusion, these results suggest that life-sized figures do indeed induce stronger embodiment effects in MR. 相似文献

In this study, we investigated the influence of children’s level of executive functioning on two types of metamemory knowledge following a traumatic brain injury (TBI). For this purpose, 22 children (aged 7 to 14 years) who had sustained a moderate to severe TBI and 44 typically developing children were recruited. The children with TBI were divided into two groups according to the severity of their executive impairment. Injury severity was determined by the Glasgow Coma Scale (GCS) score on admission or by the duration of unconsciousness. All children were then tested on both their knowledge of general memory functioning and their level of memory self-awareness, respectively assessed using the total number of correct responses on an adapted version of a metamemory interview and a self-other discrepancy score on a questionnaire evaluating everyday memory abilities. Data analyses revealed that participants with TBI who suffered impaired executive functions demonstrated less general metamemory knowledge, and underestimated the frequency of their memory problems, compared with children with TBI who had preserved executive functions and with control participants. Considering the well-established effect of metamemory knowledge on people’s spontaneous implementation of strategies, the interest and the importance of these findings on both theoretical and clinical grounds are discussed. 相似文献

In this commentary, we argue that a generally sound therapeutic technique—Socratic questioning—is ill-suited to address a common variant of combat-related emotional and psychological distress. Specifically, moral injury is a term used to describe a syndrome of shame, self-handicapping, anger, and demoralization that occurs when deeply held beliefs and expectations about moral and ethical conduct are transgressed. Importantly, moral injury can and often does result from instances of intentional perpetration. We contend that challenging the accuracy of self-blame in such cases is conceptually problematic and potentially harmful. Such an approach is based on a questionable premise—i.e., that self-blame and resulting guilt are inherently illogical or inaccurate. Though this is often the case, it is not invariably so. We briefly describe an alternate approach—Adaptive Disclosure—that allows for accurate and legitimate self-blame when warranted but also promotes the possibilities of self-forgiveness, compassion, and moral reparation. 相似文献
