In an educational setting, we examined the relationship of learning goal orientation with goal setting and performance over time. At the first time point, we assessed levels of trait learning goal orientation and asked participants to set performance goals. At each follow‐up time point, we reported to participants their current course grade and allowed them to revise their goals. Learning goal orientation was associated with both setting higher goals and maintaining higher performance over time. Additionally, the relationship of learning goal orientation and performance was found to be mediated by goal setting.  相似文献

The microstructures of 304 stainless steels with different amounts of nanocrystalline and microcrystalline austenite prepared by an aluminothermic reaction casting, without and with annealing at 1073?K for 8?h, have been investigated by X-ray diffraction, an electron probe micro-analyser, a transmission electron microscope and a scanning electron microscope. The steels, both without and with annealing, consisted of different dual nanocrystalline and microcrystalline austenite combinations and a little nanocrystalline δ ferrite, while the average grain size of the nanocrystalline austenite increased from 19 to 26?nm and volume fraction of the microcrystalline austenite increased from 17 to 30% after annealing. The tensile strength of the steel was dramatically increased from 500 to 1000?MPa and the tensile elongation ratio increased from 8 to 12% after annealing. However, the tensile strength was decreased to 600?MPa and the tensile elongation ratio increased from 12 to 22% after an annealing at 1273?K. The combination of dual nanocrystalline and microcrystalline austenite obtained after the annealing at 1073?K results in the best tensile properties.  相似文献

同一个记忆源检测任务是否可以依赖两种不同的加工——无意识启发式加工和有意识系统式加工,是源检测加工机制研究探索的一个重要问题。本研究拟借助加工分离程序来分离同一个源检测任务中的启发式和系统式加工,并进一步考察了启发式和系统式加工受刺激呈现时间的影响。结果发现:位置源检测任务依赖于启发式和系统式两种加工,且随着刺激呈现时间的增长,系统式加工的贡献显著地提高,启发式加工的贡献却无显著提升。这一结果既验证了记忆源检测的双加工机制,也暗示了两种加工在加工深度上的差异。  相似文献

This study tested a model that links stress, social support, problem‐focused coping, and well‐being. First, it looks at how high support significantly moderated the association between stress and well‐being. Next, the students' problem‐focused coping was seen as mediating this moderated association. Finally, a 3‐way interaction of stress, social support, and avoidant coping revealed that only frequent use of avoidant coping accelerated the association between stress and well‐being in a negative way at both low and high support.  相似文献

Transdiagnostic interventions make use of eclectic treatment strategies to address multiple diagnostic problem sets linked by common underlying etiological or maintaining mechanisms. A good transdiagnostic treatment relies on strategies with empirical support and is flexible enough to accommodate diverse problems. As such, transdiagnostic treatments have numerous potential advantages over traditional approaches, including increased efficiency, practicality, efficaciousness, and effectiveness. Translation of transdiagnostic therapies to youth populations is in its nascent stages. This introduction reviews the special series in adaptations of transdiagnostic treatments to youth population. It will define transdiagnostic therapies, discuss potential advantages of such an approach, and then review each of the special series articles.  相似文献

Event-related potentials (ERPs) are now widely collected in psychological research to determine the time courses of mental events. When event-related potentials from treatment conditions are compared, often there is no a priori information on when or how long the differences should occur. Testing simultaneously for differences over the entire set of time points creates a serious multiple comparison problem in which the probability of false positive errors must be controlled, while maintaining reasonable power for correct detection. In this work, we extend the factor-adjusted multiple testing procedure developed by Friguet, Kloareg, and Causeur (Journal of the American Statistical Association, 104, 1406-1415, 2009) to manage the multiplicity problem in ERP data analysis and compare its performance with that of the Benjamini and Hochberg (Journal of the Royal Statistical Society B, 57, 289-300, 1995) false discovery rate procedure, using simulations. The proposed procedure outperformed the latter in detecting more truly significant time points, in addition to reducing the variability of the false discovery rate, suggesting that corrections for mass multiple testings of ERPs can be much improved by modeling the strong local temporal dependencies.  相似文献

注意捕获与自上而下的加工过程   总被引:2,自引:0,他引:2  
注意捕获对揭示两种控制过程——自下而上的加工与自上而下的加工之间的关系有着重要的研究意义。在当前对注意捕获的研究中,主要存在两大类的实验范式:线索化范式与视觉搜索范式;涉及以下几个方面:刺激驱动的注意捕获与自上而下控制的关系;注意捕获是否涉及注意的空间转移;刺激的显著性对注意捕获的影响;实验范式对注意捕获的影响。总的来说,没有任何一种视觉刺激能绝对的独立于自上而下的控制之外来捕获注意,因此也可以这样认为,注意捕获被默认为是一种自动化的过程,但这个自动化的过程可以被内源性的调节所抑制或者易化。  相似文献

The Dynamics of Cyber China: The Characteristics of Chinese ICT Use   总被引:2,自引:1,他引:1  
This paper provides a preliminary examination of the use of information and communication technologies (ICTs)—limited to mobile phone and internet use—in contemporary China. Based on fieldwork undertaken since 2003 in Guangzhou and Beijing, the paper focuses on the relationship between society and technology in the Chinese cultural context. An analysis of the data on ICT use in China shows how Chinese cultural traits and the speed of the ICT evolution in China have combined to bring about a unique cyber experience. This analysis may be helpful to other scholars who wish to compare the impact of ICTs in various cultures or who are interested in discovering how Mainland China went ‘cyber’.

The authors examined cultural and individual differences in the relation between daily events and daily satisfaction. In a preliminary study, they established cross-cultural equivalence of 50 daily events. In the main study, participants in the United States, Korea, and Japan completed daily surveys on the 50 events and daily satisfaction for 21 days. The multilevel random coefficient model analyses showed that (a) the within-person association between positive events and daily satisfaction was significantly stronger among Asian American, Korean, and Japanese participants than among European American participants and (b) the within-person association between positive events and daily satisfaction was significantly weaker among individuals high in global life satisfaction than among those low in global life satisfaction. The findings demonstrate a weaker effect of positive events on daily well-being among individuals and cultures high in global well-being.  相似文献
