Two new methods to estimate the asymptotic covariance matrix for marginal maximum likelihood estimation of cognitive diagnosis models (CDMs), the inverse of the observed information matrix and the sandwich-type estimator, are introduced. Unlike several previous covariance matrix estimators, the new methods take into account both the item and structural parameters. The relationships between the observed information matrix, the empirical cross-product information matrix, the sandwich-type covariance matrix and the two approaches proposed by de la Torre (2009, J. Educ. Behav. Stat., 34, 115) are discussed. Simulation results show that, for a correctly specified CDM and Q-matrix or with a slightly misspecified probability model, the observed information matrix and the sandwich-type covariance matrix exhibit good performance with respect to providing consistent standard errors of item parameter estimates. However, with substantial model misspecification only the sandwich-type covariance matrix exhibits robust performance. 相似文献

This study explores how an environmental factor (i.e., a perceived open climate) shapes lesbian, gay, and bisexual (LGB) employees' job satisfaction and job anxiety through the mediating role of self‐concealment. It also investigates the moderating role of self‐acceptance. Results from 315 LGB employees supported the conclusion that a perceived open climate for minority sexuality increased job satisfaction and decreased job anxiety. The open climate–job anxiety relationship was mediated by self‐concealment, and both stages of this mediation process were moderated by self‐acceptance. These findings offer useful insights for counselors and managers to help LGB individuals improve their workplace psychological experiences. 相似文献

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading. 相似文献

Drawing on the Conservation of Resources Theory by Hobfoll, we examined the relationships between abusive supervision, job insecurity, locus of control, and employees’ innovative behavior. Using self‐reported data collected from employees among four enterprises in China (N = 641), we found that abusive supervision was positively correlated with job insecurity. In contrast, both job insecurity and abusive supervision were negatively correlated with employees’ innovative behavior, with the impact of abusive supervision on innovative behavior being mediated by its effect on job insecurity. Having an external locus of control that served as a buffering factor for employees, mitigating the relationship between abusive supervision and job insecurity. These findings complement the existing research on the impacts of abusive leadership, providing practical information for enterprises on how to enhance levels of innovation and vitality among employees. 相似文献

本研究以338名学前儿童为被试,采用母亲报告法探究了学前儿童睡眠时间与问题行为之间的关系,以及儿童消极情绪性的调节作用。结果发现:(1)睡眠总时长对儿童内化和外化问题行为的主效应显著,而睡眠总时长与消极情绪性对儿童内化和外化问题行为的交互作用不显著;(2)夜间睡眠比对儿童内化问题行为的主效应显著,对儿童外化问题行为的主效应不显著;夜间睡眠比与消极情绪性对儿童内化问题行为的交互作用显著,即对高消极情绪性的儿童,夜间睡眠比能够显著负向预测其内化问题行为,而对低消极情绪性的儿童,夜间睡眠比对其内化问题行为的预测并不显著;夜间睡眠比与消极情绪性对儿童外化问题行为的交互作用不显著。 相似文献

This study investigates the longitudinal predictors of the development of Chinese word reading skills and potential bidirectional relationships between Chinese word reading and oral language skills. We examine, in a 2‐year longitudinal study, a wide range of theoretically important predictors (phonological awareness, tone awareness, morphological awareness, visual skills, rapid automatized naming, Pinyin knowledge, and vocabulary knowledge) of reading in 143 primary‐school children living in mainland China. Initial levels of reading were predicted by vocabulary knowledge, phonological awareness, and visual discrimination skills. Only initial reading levels predicted growth in reading. Initial reading also predicted growth in vocabulary knowledge and morphological construction. This pattern demonstrates that the early stages of learning to read in Chinese places demands on semantic (vocabulary) and visual skills in addition to phonological skills. Furthermore, early levels of word reading predict the growth of vocabulary knowledge and morphological awareness suggesting that the development of these oral language skills is facilitated by learning to read. 相似文献

预测编码被认为是脑与复杂环境交互的重要机制之一, 有效感知外界环境并对未来事件做出预测, 对个体生存有着至关重要的意义。人类大脑会基于感觉输入以迭代的方式持续优化表征外部环境的内部模型, 并不断预测接下来的感觉输入。以听觉模态为例, 人类及动物对声音重复和听觉变化的神经反应(如失匹配负波和刺激特异性适应)是大脑预测编码的重要体现, 表现为重复抑制和预测误差。结合人类和动物模型在此理论框架下开展跨物种研究将有助于加深我们对听觉加工, 甚至是大脑工作机制的认识。 相似文献

Healthy diet and physical activity have consistently been found to be positively correlated; however, most health behavior theories are focused on regulation of changes in single, rather than multiple, behaviors. Thus, this study explored the mechanism of the carry-over effect between diet and physical activity by conducting a longitudinal study with 706 participants to test the bottom-up and top-down hypotheses of hierarchical self-efficacy (SE). At Time 1 (baseline) and Time 3 (4 weeks after baseline), dietary behavior, physical activity, and self-efficacies of these behaviors (at the contextual level) were measured, while at Time 2 (2 weeks after baseline), general SE (at the general level) was assessed. Mediation analysis and structural equation models supported both the bottom-up and top-down hypotheses for different levels of self-efficacies, suggesting that hierarchical SE is an important factor underlying the carry-over mechanism between diet and physical activity. 相似文献
