The resilience status of Chinese left-behind children in rural areas: a meta-analysis

The resilience has become the main trend of the left-behind children's (LBC) mental health research. To evaluate the resilience status of Chinese LBC in rural areas, a meta-analysis was performed. Relevant studies were identified using electronic databases from 1990 to 2017. Pooled weighted mean difference (WMD) and 95% confidence interval (95% CI) were calculated with fixed and random effects models. A total of 14 cross-sectional studies with 9777 individuals were included in this meta-analysis. The results showed there was significant difference in the aspects of family support and RSCA (Resilience Scale for Chinese Adolescents) total score between LBC and non-left-behind children (NLBC). After stratification subgroup, significant difference in RSCA total score was also found in subgroup with sample size ≥700 and target population (LBC) between LBC and NLBC. In addition, there was no significant difference in resilience of male and female among LBC (P >0.05). We also found RSCA total score of LBC whose one parents migratingwere higher than both parents (P <0.05) and the time of parental migration (≤2 years) were higher than others (>2 years). In conclusion, more attention should be paid to the LBC, especially both parents migrating or parental migration (>2 years).     

关于青少年应对风格的调查研究

该文采用天津师大编制的应对风格量表对江西省4072名从小学五年级到大学三年级的学生进行了调查,目的是了解青少年应对风格现状及其发展特点,以及性别、独生子女、城乡等因素对应对风格的影响。结果发现：总体而言,青少年应对风格倾向“注重问题的应对策略”,较少采用“注重情绪表达的策略”;在初一年级前后,个体采用的应对方式最为多样化;男女生的应对风格差异在高中后较为明显,男生更倾向于采用“注重问题的应对策略”,女生更倾向于采用“针对情绪的身体策略”;城镇学生的应对方式比农村学生更为多样化,并且更倾向于针对问题本身的策略;家庭收入只对“针对情绪的行为策略”产生影响,高、低两端收入家庭的学生更倾向于采用“针对情绪的行为策略”;是否独生子女在应对风格上不存在显著差异。     

浅析信息接受者认知调节在组织沟通中的作用

组织沟通是实现组织目标的基础,组织沟通效果受沟通要素、组织结构、个人因素以及组织文化和社会环境等众多因素的影响,而信息接受者的认知调节作用在沟通过程中起重要作用,决定着沟通有效的程度。本文旨在为今后研究沟通效果的改善策略提供依据。     

学习与脑可塑性的研究进展及其教育意义

脑可塑性是指脑在外界环境和经验的作用下不断塑造其结构和功能的能力.本文阐述了神经科学与认知神经科学关于学习影响动物脑与人脑结构与功能的研究进展.研究表明,学习与经验可以改变脑皮层的厚度与树突的结构,增加树突棘的数量,修饰其形状,对脑的功能代表区产生影响.学习与脑可塑性的多层面研究为理解学习的本质规律以及教育研究与实践提供重要的启示.     

珠心算训练儿童加法心算的ERP早成分研究

采用事件相关电位(ERP)的方法,对32名儿童进行了双位数加法心算实验,探讨了珠心算训练方式对儿童加法心算加工早期感知觉的影响。研究结果表明,与非珠心算训练儿童相比,在加法心算过程的早期阶段,珠心算训练儿童枕部P1、额中央区的N1波幅增大,而颞枕区N170以及额中央区P2波幅减小。本研究结果发现珠心算训练对儿童心算过程的早期感知有显著影响。     

3、4岁儿童数数的规则及其策略运用的研究

数数能力是儿童用于建构其数学知识系统的重要工具,是儿童早期获得的最基本的数认知能力之一。本研究以234名3、4岁儿童为被试,采用个别测查法对儿童数数的规则及其策略运用进行了考察。研究发现：(1)随着数列数目的增大,3、4岁儿童数数精确性呈下降趋势,但4岁儿童在各项任务上的数数精确性显着高于3岁儿童;(2)3、4岁儿童在数7、10、15、30任务上的错误表现有显着差别;(3）3、4岁儿童数数策略运用存在显着差别．协方差分析显示。策略使用在数7和数10任务上具有显着效应。

托马斯主义的先验转向—麦利切尔对托马斯主义与康德先验哲学的整合

在19世纪末和20世纪初,因罗马天主教延的号召和支持而不断出现的新经院哲学本质上是传统托马斯主义的复兴。麦利切尔首创的“先验托马斯主义”是新经院哲学中既引人注目而又倍受争议的一种新思潮,它致力于托马斯主义与康德先验哲学的对话,并努力将两者有机地整合在一起,从而对托马斯主义进行了先验转向之处理。本文在介绍先验托马斯主义产生的历史背景以及麦利切尔对知识论进行的历史检视和方法论反省的基础上,重点阐述麦利切尔在知识论上对托马斯的形上批判与康德的先验批判进行的有机整合。     

Chinese character recognition in mirror reading: evidence from event-related potential

As is well known, mirror reading in language requires recognition of words and letters in mirror-reversed pattern compared with normal reading, and the cognitive mechanism underlying the mirror reading may involve two critical processes: visuospatial transformation and linguistic regulation. Chinese characters, different from English, are characterized by some unique features in orthography and spelling. Using ERP techniques, the present study investigated neural correlates underlying the mirror reading of Chinese characters, and whether the cognitive processes underlying the recognition of mirrored Chinese characters is different from those of alphabetic words. Twelve native Chinese speakers participated in the experiment, during which they were instructed to make an animal/nonanimal distinction. The stimuli varied with the word category (animal vs nonanimal) and presentation format (normal vs mirror-reversed). The data analyses focused on three aspects: the reaction times (RT) for Chinese words of normal and mirror-reversed formats, peak latencies, and peak amplitudes of ERP components elicited by mirror-reversed and normal Chinese words. The results from implicit reading provide evidence for a mirror-reversed effect. The behavioural data showed that mirror-reversed words were more difficult to identify than normal words, with RTs delayed for mirror-reversed words over normal words. Moreover, a clear N2 component, with maximal activity occurring at 200-250ms interval (N2), was more negative for mirror-reversed words than for normal words at posterior regions. However, there were no latency differences between normal and mirror-reversed words. The occipital N2 might be closely related to abstract word form representation. Larger N2 amplitude in response to mirror-reversed Chinese words is interpreted as reflecting visuospatial transformation in order to compensate for impaired word form analysis. The result of no N2 latency delay indicated that word form analysis and visuospatial transformation might be processed in parallel.
