Motion of the body center of mass (CoM) can often indicate the overall effect of the strategy of forward progression used. In the present study, focus is placed on trunk movements in the sagittal, coronal, and transverse/rotation plane, as well as placement of the CoM, during gait in children with juvenile idiopathic arthritis (JIA). Seventeen children with JIA, all with polyarticular lower extremity involvement were examined before and approximately two weeks after treatment with intra-articular cortico-steroid injections. Movement was recorded with a 6-camera 3D motion analysis system in both the children with JIA and in 21 healthy controls. Trunk and center of mass movements were compared between JIA and controls, and effects of intra-articular cortico-steroid treatment were evaluated. Children with JIA were more posteriorly tilted in the trunk, contrary to the common clinical impression, and had their CoM placed more posterior and off-centred, which may have been a result of pain. With such knowledge, it might be possible to better understand the effects of their pain and involvement, and ultimately to plan a treatment strategy for improving their gait patterns. 相似文献

The relation between worrying and individuals' concerns was examined in a sample of 197 college students. Participants described the five undesirable outcomes that they thought about most often, indicated how likely they thought the outcomes were, and how upset they would be by them. Worry severity was measured using the Penn State Worry Questionnaire. The relation between worry severity and the life domains about which individuals were concerned was quite weak. In contrast, as predicted, greater worry was associated with higher probability and cost estimates. In addition, cost estimates moderated the relation between worry severity and probability estimates. The potential importance of perceived threat for understanding worrying is discussed. 相似文献

Although intrusive images are a hallmark of post-traumatic stress disorder (PTSD) and also occur in depression, little is known about the differences and similarities of such images in these conditions. Our study focuses on the qualities and triggers of intrusive images and responses to them in three groups--patients with PTSD, and depressed patients with and without trauma (n=65)-to highlight the diagnostic specificity of intrusive images for PTSD and depression. We distinguished intrusive images from verbal intrusive cognitions such as rumination and intrusive (brief) lexical thoughts. Consistent with the literature, the intrusive images of PTSD patients had a more "here-and-now quality" and were perceived more visually compared to those of both depressed groups. The groups showed a good deal of similarity concerning other image qualities. Most importantly, the intrusive images in PTSD and depressed patients with and without trauma were perceived as similarly distressing. Rumination and intrusive (brief) lexical thoughts were two of the five most named triggers of intrusive images. Limitations, such as the lack of a control group, and the clinical implications of these results are discussed, demonstrating the need to help non-PTSD patients with and without trauma to deal with intrusive images. 相似文献

This qualitative study explores how 29 Swedish patients with Multiple Endocrine Neoplasia type 1 (MEN1) experience living
with the condition, appraisal of the clinical follow-up program, and surveys their future expectations. The aim of this study
is to build knowledge about this patient group in order to provide optimal care. The participants describe physical, psychological,
and social limitations in their daily activities and how these limitations influence quality of life. Our findings indicate
that a majority of patients have adjusted to their situation, describing themselves as being healthy despite physical symptoms
and treatment. The participants received decent care in the clinical follow-up program, - however, greater effort should be
put into patient information. These patients might benefit from genetic counseling. Health professionals involved should recognize
their potential impact and influence on a patient’s ability to adjust to these circumstances. Antonovsky`s Sense of Coherence
theory is used to discuss these findings. 相似文献

Development and validation of the cognitive style indicator 总被引:3,自引:0,他引:3
The authors describe the development and validation of the Cognitive Style Indicator (CoSI) using 3 diverse samples (N = 5,924; N = 1,580; and N = 635). Reliability, item, and factor analyses demonstrated the internal consistency and homogeneity of 3 cognitive styles: knowing, planning, and creating. The authors also found substantial support for the instrument's convergent and discriminant validity by including other cognitive style instruments and personality and academic performance measures in the validation process. Criterion-related validity was confirmed by examination of the relation between these cognitive styles and work-related characteristics. The main contributions of this study are (a) the further refinement of the analytic-intuitive cognitive style dimension by splitting the analytic pole in a knowing and a planning style and (b) the development of a valid and reliable cognitive style instrument for use in organizations. 相似文献

ABSTRACT— Becoming a bilingual can change a person's cognitive functioning and language processing in a number of ways. This study focused on how knowledge of a second language influences how people read sentences written in their native language. We used the cognate-facilitation effect as a marker of cross-lingual activations in both languages. Cognates (e.g., Dutch-English schip [ship]) and controls were presented in a sentence context, and eye movements were monitored. Results showed faster reading times for cognates than for controls. Thus, this study shows that one of people's most automated skills, reading in one's native language, is changed by the knowledge of a second language. 相似文献

Background Cultural capital in families and especially, the educational level of parents, has during the last decades been found to be the most important dimension of socio‐economic influence on school performance. How the transmission of cultural capital over generations is concretized is however not yet fully investigated. Aims The aim is to unfold the influence of home background and more specifically, to reveal some important mediating factors between the educational levels of parents and the reading achievement levels of children. Sample Data comes from the Swedish participation in Progress in International Reading Literacy Study 2001 conducted by the The International Association for the Evaluation of Educational Achievement and comprises some 10,000 students in grade 3. Methods The effects of parents' education on reading achievement are estimated with structural equation modelling. Results The results reveal that the total effect of parents' education is substantial and that almost half of this effect is mediated through other variables, i.e. the number of books at home, early literacy activities, and emergent literacy abilities at the time for school start. The article thus identifies some of the mechanisms through which parents' education exert an influence on children's literacy development. Conclusions Cultural reproduction starts in the very early childhood, in informal settings where reading aloud is an important activity. The knowledge of written language that children have at the time for school‐start influences further reading acquisition. 相似文献

The present research investigated the role of cognitive balance vs. associative transfer of valence in attitude change. Participants first formed positive or negative attitudes toward several source individuals. Subsequently, participants were shown source–target pairs along with information about the source–target relationship (‘likes’/‘dislikes’). Afterwards, participants’ attitudes toward the sources were changed by means of information that was opposite to the initially induced attitude. In a control condition, initial source attitudes remained unqualified. Results in the control condition showed that initially formed attitudes and available relationship information produced target evaluations that were consistent with the notion of cognitive balance. However, when attitudes toward the sources changed, target evaluations directly matched attitudes toward individually associated sources, irrespective of the relation between source and target. These results suggest that associative transfer of valence can disrupt the emergence of cognitive balance after attitude change. 相似文献

- Environmental policy makers and marketers are attracted by the notion of green consumerism. Yet, green consumerism is a contested concept, allowing for a wide range of translations in everyday discursive practices.
- This paper examines how young consumers construct their images of green consumerism. It makes a close reading of three narratives reflecting available subject positions for young green consumers: the Antihero, the Environmental Hero and the Anarchist.
- It reveals problems in the prevailing fragmented, gendered and individualistic notions of green consumerism, and discusses implications for policy and marketing practitioners.

In this cross-sectional study, we investigated whether the combination of the presence of callous-unemotional (CU) traits and emotional deficits to distressing stimuli, assessed by a computerized dot-probe task, enhanced the statistical prediction of aggression and delinquency in a sample of 88 detained and predominantly African-American (68%) adolescents (M age = 15.57; SD = 1.28). Overall, self-reported CU traits were associated with self-report measures of aggression and delinquency, but not with official records of arrests. However, there was an interaction between CU traits and emotional deficits for predicting self-reported aggression, self-reported violent delinquency, and a record of violent arrests. Youth high on CU traits and who showed a deficit in their responses to visual depictions of distress showed the highest levels of aggression and violent delinquency. 相似文献
