Cognitive control is essential to flexible, goal-directed behavior under uncertainty, yet its underlying mechanisms are not clearly understood. Because attentional functions are known to allocate mental resources and prioritize the information to be processed, we propose that the attentional functions of alerting, orienting, and executive control and the interactions among them contribute to cognitive control in the service of uncertainty reduction. To test this hypothesis, we examined the relationship between cognitive control and attentional functions. We used the Majority Function Task (MFT) to manipulate uncertainty in order to evoke cognitive control along with the Revised Attention Network Test (ANT-R) to measure the efficiency and the interactions of attentional functions. A backwards, stepwise regression model revealed that performance on the MFT could be significantly predicted by attentional functions and their interactions as measured by the ANT-R. These results provide preliminary support for our theory that the attentional functions are involved in the implementation of cognitive control as required to reduce uncertainty, though further investigation is needed.  相似文献

The objective of this study was to examine (a) anxiety and depression symptoms in children with Asperger syndrome (AS) compared to children with attention-deficit/hyperactivity disorder (ADHD) and children with depressive disorder; (b) parental anxiety and depressive symptoms in the three groups; and (c) the association between the anxiety and depression symptoms of children and their parents. The emotional and behavioral problems of 56 children with AS (48 boys, 8 girls, mean age, 9.39 ± 2.01 years) were compared with 56 ADHD children and 56 depressive disorder children, matched for age and sex. Their parents’ anxiety and depression symptoms were also compared. Trait-anxiety and internalizing problems in AS children were higher than those in ADHD children and as high as those in depressive disorder children (F = 8.83, p < 0.001 and F = 8.21, p < 0.001). Parents’ anxiety and depression symptoms did not differ among the three groups, but correlations between maternal anxiety and depression and children’s emotional and behavioral problems were most prominent in the AS group. We suggest that the assessment and treatment of children with AS should involve detailed assessment, possible concomitant treatment for comorbid anxiety and depression, and parental education about the effect of parental emotional states on children.  相似文献

救护车车载物品是院前急救的基础和保障,对院前急救的效率和质量具有十分重要的意义.本文总结并分析了美国救护车车载物品和院前急救的特点:更加注重院前急救人员的个人防护;更加注重对患者的救出;更加注重心脏按压板的运用;更加注重急救箱物品配置的科学性;更加注重对普通物品的利用;更加注重患者的转运.美国西雅图20世纪70年代抢救5 120例院外猝死患者,复苏成功至康复出院者达28.9%;我国上海医疗救护中心1999年抢救猝死患者4 374名,复苏成功率1.35%.我国院前抢救猝死的成功率明显低于美国,或与中美救护车车载物品的不同相关.了解美国救护车车载物品的特点,对我国的院前急救或有借鉴作用.  相似文献

This study examined psychological well-being influences of personal factors on regular sponsorship of, or donation to, African children living in Africa. Study participants (N = 597) were 338 Koreans (50.3% female, n = 170) and 259 Chinese (56.8% female, n = 147). They responded to measures of psychological well-being, individual social responsibility, social impression management, and subjective norms. Following multiple group analyses applying structural equation modelling, subjective well-being influenced psychological well-being among the Korean donors; whereas social responsibility influenced psychological well-being among the Chinese donors. In both the Korean and Chinese groups, psychological well-being was associated with an increased regular sponsorship of African children. Latent ethno-cultural personal orientations appear to explain psychological well-being with donation activity.  相似文献

To examine the reciprocal relations between teacher–child relationships and children's behavior problems, the authors analyzed cross-lagged longitudinal data on teacher–child relationships and children's internalizing and externalizing problems using a structural equation modeling approach. The homeroom teachers of 105 first-year preschoolers aged 2–3 years filled in the Student–Teacher Relationship Scale and the Child Behavior Checklist/2–3, first at 3 months after the children's preschool entrance and then at the end of the first preschool year. Results showed significant cross-wave reciprocal relations between externalizing problems and teacher–child conflict and significant cross-wave relation from early internalizing problems to later teacher–child conflict. However, the cross-wave associations between internalizing and externalizing problems and teacher–child closeness were not significant.  相似文献

This research explores the emergence of student creativity in classroom settings, specifically within two content areas: science and social studies. Fourteen classrooms in three elementary schools in Korea were observed, and the teachers and students were interviewed. The three types of student creativity emerging in the teaching and learning process found in this research were: (a) heuristic creativity when the students express their thoughts about a new concept based on their experience, (b) interpretive creativity when the students explain the meaning of materials based on students' knowledge, and (c) integrative creativity when students generate new solutions or make new products based on their internalized knowledge. The study results will challenge teachers to find instances of student creativity in their teaching and learning situations and to facilitate student creativity when the students interpret data or materials related to the contents of the curriculum.  相似文献

This study examined the mediation effect of career decision self‐efficacy in relation to work values and career decision status. The authors surveyed 308 college students about their own intrinsic (e.g., helping others) and extrinsic (e.g., high income) work values and those of significant others, career decision self‐efficacy, and career decision status. The results indicated that the intrinsic and extrinsic work values of significant others were related to the intrinsic and extrinsic work values of the self and that intrinsic work values were more adaptive than extrinsic work values in career development.  相似文献

Using data from an original two‐wave panel survey of California high school students and a two‐wave panel survey of high school students in Chicago, we find that different pedagogical approaches influence different forms of civic and political engagement. Specifically, controlling for prior levels of engagement and demographic factors, we find that open discussion of societal issues promotes engagement with political issues and elections. In contrast, service learning opportunities increase community‐based and expressive actions. Both kinds of opportunities promoted commitments to participatory citizenship. These patterns can teach us about the kinds of opportunities (both in school and out) that can shape adolescents' civic and political development.  相似文献
