以363名初中阶段流动儿童为被试,采用问卷法考察学业自我妨碍在流动儿童个体和群体歧视知觉与学业倦怠关系中的中介作用,以及认同整合的调节作用。结果如下:(1)个体和群体歧视知觉正向预测流动儿童学业倦怠;(2)学业自我妨碍在流动儿童个体和群体歧视知觉与学业倦怠关系中起中介作用;(3)认同整合会调节个体歧视知觉、学业自我妨碍对学业倦怠的影响。 相似文献

以310名幼儿父亲为研究对象,采用流行病调查中心抑郁量表、父母教养能力感量表的教养效能感分问卷、父母教养方式评价量表和Conners儿童行为问卷,考察父亲教养效能感和教养方式在父亲抑郁与幼儿问题行为间的中介作用。结果显示:(1)父亲抑郁、专制粗暴、情感联系和幼儿问题行为两两之间均显著正相关,父亲教养效能感、民主关怀、宽容理解两两之间均显著正相关,父亲教养效能感、民主关怀、宽容理解分别与父亲抑郁、专制粗暴、情感联系和幼儿问题行为两两之间显著负相关;(2)父亲抑郁对幼儿问题行为具有显著的正向预测作用;(3)父亲教养效能感和自身的民主关怀、专制粗暴、情感联系不仅分别在父亲抑郁与幼儿问题行为之间起部分中介作用,而且在父亲抑郁与幼儿问题行为之间起链式中介作用。 相似文献

This paper discusses the theoretical role of parental self-efficacy, or parents' beliefs in their competence and effectiveness in the parental role, as a mediator of relations between parent–child risk and parental sensitivity. Evidence is marshalled from studies of parenting in the contexts of maternal depression and child health risk to support the premise that parent–child characteristics affect parental sensitivity indirectly via their more direct impact on parental feelings of efficacy, and that parenting efficacy represents the ‘final common pathway’ in the prediction of parenting sensitivity. Also considered in this working model are specific social-contextual factors as independent contributors to parenting efficacy and as possible moderators of relations between parent–child characteristics and self-efficacy. Implications for intervention are discussed. © 1996 John Wiley & Sons, Ltd. 相似文献

Barry H. Schneider 《Aggressive behavior》1991,17(6):301-311
Social skills training and desensitization interventions were conducted with 41 institutionalized aggressive children aged 7–13. Subjects were randomly assigned after blocking by aggression and cooperative play to either of the treatments. Dependent measures were direct observations of playground play and teacher ratings. Subjects in the social skills program mastered the basic cognitive skills presented to them. Observational data indicated that both groups experienced marked reduction in aggressive behavior and increases in cooperative play. The social skills training intervention engendered incremental improvement in aggression in comparison to the desensitization condition. However, none of the behavioral changes evident in the observations were reflected in teacher ratings. 相似文献

Working memory training has been shown to improve performance on untrained working memory tasks in typically developing children, at least when compared to non‐adaptive training; however, there is little evidence that it improves academic outcomes. The lack of transfer to academic outcomes may be because children are only learning skills and strategies in a very narrow context, which they are unable to apply to other tasks. Metacognitive strategy interventions, which promote metacognitive awareness and teach children general strategies that can be used on a variety of tasks, may be a crucial missing link in this regard. In this double‐blind randomized controlled trial, 95 typically developing children aged 9–14 years were allocated to three cognitive training programmes that were conducted daily after‐school. One group received Cogmed working memory training, another group received concurrent Cogmed and metacognitive strategy training, and the control group received adaptive visual search training, which better controls for expectancy and motivation than non‐adaptive training. Children were assessed on four working memory tasks, reading comprehension, and mathematical reasoning before, immediately after, and 3 months after training. Working memory training improved working memory and mathematical reasoning relative to the control group. The improvements in working memory were maintained 3 months later, and these were significantly greater for the group that received metacognitive strategy training, compared to working memory training alone. Working memory training is a potentially effective educational intervention when provided in addition to school; however, future research will need to investigate ways to maintain academic improvements long term and to optimize metacognitive strategy training to promote far‐transfer.

Over the last 15 years, researchers have been increasingly interested in understanding the nature and development of children’s selective trust. Three meta‐analyses were conducted on a total of 51 unique studies (88 experiments) to provide a quantitative overview of 3‐ to 6‐year‐old children’s selective trust in an informant based on the informant’s epistemic or social characteristics, and to examine the relation between age and children’s selective trust decisions. The first and second meta‐analyses found that children displayed medium‐to‐large pooled effects in favor of trusting the informant who was knowledgeable or the informant with positive social characteristics. Moderator analyses revealed that 4‐year‐olds were more likely to endorse knowledgeable informants than 3‐year‐olds. The third meta‐analysis examined cases where two informants simultaneously differed in their epistemic and social characteristics. The results revealed that 3‐year‐old children did not selectively endorse informants who were more knowledgeable but had negative social characteristics over informants who were less knowledgeable but had positive social characteristics. However, 4‐ to 6‐year‐olds consistently prioritized epistemic cues over social characteristics when deciding who to trust. Together, these meta‐analyses suggest that epistemic and social characteristics are both valuable to children when they evaluate the reliability of informants. Moreover, with age, children place greater value on epistemic characteristics when deciding whether to endorse an informant’s testimony. Implications for the development of epistemic trust and the design of studies of children’s selective trust are discussed. 相似文献

大量从“能力”角度来探讨个体早期数学发展的研究仅专注于儿童早期的数学知识和技能, 而忽略了可能与儿童早期数学能力相关的方面。近年来, 数学认知发展研究者逐渐开始关注自发数量聚焦(Spontaneous focusing on numerosity, SFON), 即个体对环境中数量相关信息自发注意的认知倾向。SFON被视为其他数学聚焦倾向概念的基础, 但与自发数字聚焦(SAN)、自发阿拉伯数字聚焦(SFONS)和自发数量关系聚焦(SFOR)之间的联系仍需进一步明晰。作为数学表现的领域特异预测因子, 个体SFON的发展轨迹和作用机制是当前研究的重点所在。未来可从数学动机、数学焦虑等角度进一步探讨SFON的作用机制, 改良与创新SFON测量工具, 同时需深入推进家庭和学校场合的SFON干预研究。 相似文献

基于社会学习理论的父母教养课程被普遍视为预防儿童青少年行为问题以及促进儿童身心健康的“黄金标准”。父母积极教养课程(Triple P – Positive Parenting Program)是其中的主要代表。本文详尽介绍了Triple P的理论基础、干预体系、课程内容以及实证研究结果,分析了该课程存在的优势以及缺陷。此外,本文结合中国家庭的特点和需求,探讨了该课程运用于中国家庭时可能会遇到的挑战,同时提出了改良的方向,为家庭干预实践工作者和研究人员提供了新的视角。 相似文献
