以河南省某市四所幼儿园大、中、小班共196名学前儿童及其父母和教师为研究对象,基于家庭系统理论,采用父、母填写的父母感知协同教养量表和亲子关系量表、母亲填写的儿童早期同胞关系质量问卷和幼儿教师报告的儿童行为量表探讨亲子关系、同胞关系在父母感知协同教养与学前儿童社会行为之间的中介作用。结果发现:(1)母子冲突和母子亲密分别在母亲感知协同教养与同胞冲突和同胞温暖间起部分中介作用;父子冲突和父子亲密分别在父亲感知协同教养与同胞冲突和同胞温暖间起完全中介作用;(2)父/母子冲突和同胞冲突在母亲感知协同教养和儿童攻击行为间起链式中介作用;父子冲突和同胞冲突在父亲感知协同教养和儿童攻击行为间起链式中介作用。  相似文献

对真人面孔与卡通面孔记忆线索的比较研究,有助于深入认识儿童的面孔认知机制。采用“学习-再认”范式,以内部线索面孔、外部线索面孔和完整面孔为刺激材料,探究面孔线索对4~6岁幼儿真人与卡通面孔记忆的影响。结果发现:(1)女童对真人面孔的记忆显著优于卡通;(2)对卡通面孔的记忆,男童显著优于女童;(3)对真人面孔:完整面孔记忆显著优于内部线索面孔与外部线索面孔;对卡通面孔:外部线索面孔记忆最佳,其次完整面孔,内部线索面孔最低;(4)幼儿对外部与内部线索面孔的记忆能力随年龄逐步提高,6岁显著优于4岁。综上,幼儿对真人面孔与卡通面孔的记忆模式存在差异;且面孔类别、性别、面孔线索与年龄等因素均影响幼儿的面孔记忆。  相似文献

目的:研究探讨了单类内隐联想测验(Single Category Implicit Association Test,SC-IAT)测量中学生良心的可行性,并分析内隐良心和外显良心的关系。方法:采用E-prime3.0软件编制SC-IAT良心测量程序,测量了中学生内隐良心; 采用青少年良心问卷测量了中学生的外显良心,并运用相关技术分析两者之间的关系。结果:SC-IAT实验中,中学生良心的内隐效应显著,且不存在性别、独生与否、学段、家庭结构、家庭所在地等人口统计学指标上的显著差异; 内隐良心与外显良心之间的相关不显著。结论:(1)中学生良心存在积极内隐效应;(2)外显良心和内隐良心相互分离,是两个不同的建构。  相似文献

To explore parenting style, child effortful control, parenting stress, and their associations with maternal use of pressure to eat among Asian U.S. immigrant families with preschoolers. One hundred and nine Asian immigrant mothers with 3-to-5-year-old children in Maryland, United States rated their authoritative and authoritarian parenting styles, frequency of pressuring their child to eat, perceived parenting stress, and child’s effortful control. Two proposed moderated mediation models were tested using conditional process modeling. Effortful control mediated the association between authoritative parenting style and pressure to eat practices, αβ?=??0.07, p?<?0.05, and the association between authoritarian style and pressure to eat, αβ?=?0.12, p?<?0.05. Moreover, parenting stress moderated the association between child effortful control and maternal pressure to eat in the authoritarian style model, but not in the authoritative style model. Specifically, higher effortful control was associated with less use of pressure to eat at low and mean levels of parenting stress. Our findings revealed potential mechanisms underlying the associations between parenting styles and controlling feeding practices. Importantly, information learned from the present study may guide transdisciplinary efforts to design and implement culturally sensitive and family-based interventions targeting Asian immigrants’ wellbeing and obesity in the United States.

IntroductionLittle is known about the importance of the adaptive, maladaptive and neutral facets of competitive orientations among French athletes.ObjectiveThe aim of this study is to test the factorial validation and measurement invariance of the French version of the multidimensional competitive orientation inventory (FVMCOI) from the original version (MCOI, Orosz et al., 2018), which included 12 items and four factors (i.e., hypercompetitive orientation, self-developmental competitive orientation, anxiety-driven competition avoidance, and lack of interest toward competition).MethodA series of three complementary studies was carried out with a total sample of 891 competitors.ResultsFollowing cross-cultural validation methods a preliminary version of the FVMCOI was constructed and the clarity of its items was established (study 1). Then, exploratory structural equation modeling (ESEM) confirmed that the four-factor model for the FVMCOI was factorially valid, and consistent with the model of the original version. As such, the multiple-group invariance tests showed that the FVMCOI was partially invariant across both age and gender and fully invariant across type of sport, level of competition and over time (study 2). Finally, the concurrent validity of the FVMCOI was demonstrated through its expected relationships with achievement goals, competitive aggressiveness and anger in sport (study 3).ConclusionThe establishment of the FVMCOI extends the research in sport psychology by allowing an extensive psychometric study of the MCOI in the sport domain and providing deeper insights into the healthy, unhealthy, and neutral nature of competitive orientation in this context. The FVMCOI's potential practical applications in sport context, with some limitations and perspectives of this study, are also discussed.  相似文献

如何从神经生理层面刻画教育活动的人际互动模式和动态性是教育神经科学面临的一个重要挑战。人际神经科学视角为其提供了可能的解决途径; 这一新兴的视角通过记录和分析进行同一认知活动时两人或多人大脑活动之间的关联, 来揭示大脑活动的群体模式。目前, 人际神经科学方法已被应用于教育研究, 例如监控教学过程、预测教学效果和识别教学影响因素, 相应的研究成果对教育活动具有重要启示。未来的研究者可以更多地关注不同学习水平的学生大脑的互动机制及人际神经科学方法应用于技能教学及线上教学评估的巨大潜力。  相似文献

This study aimed to examine the role of positive relationships and academic achievement in predicting student well-being, i.e. subjective happiness. This study employed a longitudinal design with two waves of data collection on a sample of 786 primary school students in Hong Kong. Students completed questionnaires on parent-child relationship, teacher-student relationship, peer relationship, academic achievement, and happiness at the beginning and end of the school year. Path analysis was used for data analysis. The results indicated that Time 1 parent-child relationship and peer relationship were associated with Time 2 academic achievement, after controlling for Time 1 academic achievement. However, only Time 1 parent-child relationship was predictive of Time 2 happiness. Time 2 academic achievement was a mediator between Time 1 parent-child relationship and peer relationship and Time 2 happiness. Furthermore, girls reported higher levels of academic achievement when they perceived better peer relationship than did boys, and girls were happier when they had higher levels of academic achievement than were boys. The results suggested the need to put in place strategies to enhance parent-child relationship, peer relationship, and a harmonious classroom.
