This 1-year longitudinal study examined relations between maternal power-assertive parenting and children's social, academic and psychological adjustment in China. Participants were 316 elementary school children (mean age = 11 years, 153 boys). Maternal power-assertive parenting was assessed using children's self-reports. Data on children's social and school adjustment were obtained from peer evaluations and teacher ratings. In addition, children completed measures of loneliness and depression. Cross-lagged analyses indicated that whereas maternal power-assertive parenting was only related to later academic adjustment, children's adjustment in socioemotional and academic domains contributed to the prediction of later maternal power-assertive parenting. The results were discussed in the Chinese context.  相似文献

In this paper, we explore the use of the stochastic EM algorithm (Celeux & Diebolt (1985) Computational Statistics Quarterly, 2, 73) for large-scale full-information item factor analysis. Innovations have been made on its implementation, including an adaptive-rejection-based Gibbs sampler for the stochastic E step, a proximal gradient descent algorithm for the optimization in the M step, and diagnostic procedures for determining the burn-in size and the stopping of the algorithm. These developments are based on the theoretical results of Nielsen (2000, Bernoulli, 6, 457), as well as advanced sampling and optimization techniques. The proposed algorithm is computationally efficient and virtually tuning-free, making it scalable to large-scale data with many latent traits (e.g. more than five latent traits) and easy to use for practitioners. Standard errors of parameter estimation are also obtained based on the missing-information identity (Louis, 1982, Journal of the Royal Statistical Society, Series B, 44, 226). The performance of the algorithm is evaluated through simulation studies and an application to the analysis of the IPIP-NEO personality inventory. Extensions of the proposed algorithm to other latent variable models are discussed.  相似文献

Creativity is linked to broad scope of attention, a state or trait that allocates attentional resources over a wide range of perceptual stimuli. According to the attentional priming hypothesis, a mechanism underlying the creativity–attention link is that broad perceptual attention scope primes broad conceptual attention scope—the activation of a wide range of memory contents—which therefore facilitates creative ideation. This study aimed to test the hypothesis in three experiments using three manipulations and two creativity tasks. Experiment 1 used the Navon letter task to prime attention to global patterns or local details of composite stimuli and measured creativity via the task to generate alternative uses of daily objects. Experiment 2 modified a cue-size procedure in which participants repeatedly attended to large or small visual cues before a target stimulus appeared. Experiment 3 devised a manipulation that required participants to view and visualize images associated with broad or narrow attention and adopted the alternative uses task and the task to invent alien creatures. Across the experiments, although the results were in the predicted direction, they were non-significant. This study found no evidence that broadness of perceptual attention affects creativity.  相似文献

The authors develop and evaluate an online networking intervention, Building Relationships and Improving Opportunities (BRIO), built in conjunction with the networking literature and social cognitive theory (Bandura, 1986, 1999). A field experiment using 491 unemployed job seekers shows that the intervention increases networking intensity, networking self-efficacy, and proximal networking benefits. Further, the intervention generates higher quality reemployment through its positive effects on networking self-efficacy. Individuals who completed the intervention and were also lower in extraversion showed the most positive improvements in networking self-efficacy and reemployment quality. The study advances the literature by uncovering the mechanisms through which a networking intervention may result in improved reemployment success, and demonstrating the moderating role of individual differences in affecting intervention outcomes. The study helps practice by providing a publicly available, research-based training to improve job search networking.  相似文献

We investigated the role of inhibition failure in Obsessive Compulsive Disorder (OCD) through an eye tracking experiment. Twenty-five subjects with OCD were recruited, as well as 25 with Generalized Anxiety Disorder (GAD) and 25 healthy controls. A 3 (group: OCD group, GAD group and control group) × 2 (target eccentricity: far and near) × 2 (saccade task: prosaccade and antisaccade) mixed design was used, with all participants completing two sets of tasks involving both prosaccade (eye movement towards a target) and antisaccade (eye movement away from a target). The main outcome was the eye movement index, including the saccade latency (the time interval from the onset of the target screen to the first saccade) and the error rate of saccade direction. The antisaccade latency and antisaccade error rates for OCDs were much higher than those for GADs and healthy controls. OCDs had longer latency and error rates for antisaccades than for prosaccades, and for far-eccentricity rather than near-eccentricity stimuli. These results suggest that OCDs experience difficulty with behavior inhibition, and that they have higher visual sensitivity to peripheral stimuli. In particular, they show greatest difficulty in inhibiting behavior directed towards peripheral stimuli.  相似文献

Promises are among the most widely used tools for increasing trust in social hierarchies; yet the effect of social status on trust in promises is unknown. Here we used a modified version of the Trust Game, in which participants, acting as Investors, were paired with Trustees of varying social status who were given the opportunity to promise (or not) to return at least half of the multiplied amount (i.e., 4 × the amount invested). No return feedback was provided. Participants invested more in partners who promised than those who did not or whose promise information was concealed. Importantly, in both lab-manipulated (Exps. 1–3: math-induced) and pre-existing (Exp. 4: university-based) hierarchies, participants invested more in promises given by high status than low status partners. Post-experiment measures suggest that this may be due to greater expectations of honesty for high status than low status others. Potential explanations and implications are discussed.  相似文献

Personalized learning refers to instruction in which the pace of learning and the instructional approach are optimized for the needs of each learner. With the latest advances in information technology and data science, personalized learning is becoming possible for anyone with a personal computer, supported by a data-driven recommendation system that automatically schedules the learning sequence. The engine of such a recommendation system is a recommendation strategy that, based on data from other learners and the performance of the current learner, recommends suitable learning materials to optimize certain learning outcomes. A powerful engine achieves a balance between making the best possible recommendations based on the current knowledge and exploring new learning trajectories that may potentially pay off. Building such an engine is a challenging task. We formulate this problem within the Markov decision framework and propose a reinforcement learning approach to solving the problem.  相似文献

The goal of this study was to test the mediating effect of social decision making in the relations of anger and anger control to externalising and internalising problems. A sample of 174 Chinese adolescents (mean age = 15.36 years) completed self‐reports of trait anger, anger control, externalising problems, internalising problems and social decision making, which was operationalized as situational judgement reflecting an individual's ability to interact effectively with parents, teachers and peers. Findings indicated that adolescents' trait anger and anger control were positively related to both externalising and internalising problems. In addition, path analysis revealed that social decision making mediated the relationship between trait anger, anger control and externalising problems. Findings on the mediating effect will be discussed by referencing appraisal tendency theory and response evaluation and decision.  相似文献
