Peer rejection, negative peer treatment, and school adjustment: Self-concept and classroom engagement as mediating processes

Data gathered from a short term longitudinal study within fifth grade classrooms (n = 378) were used to evaluate two process-oriented models linking peer rejection and negative peer treatment to children's self-concept, school engagement and adjustment. Both structural models linked peer rejection, victimization, and exclusion to children's self-concept, classroom engagement, and change in achievement (fall of fifth grade to the spring). The model evaluations indicated that peer rejection predicted both exclusion and victimization and that these forms of peer treatment, in turn, predicted academic self-competence. Academic self-competence, however, only partially mediated linkages to achievement change. Parallel (i.e. direct) linkages from exclusion and victimization to both academic self-competence and engagement were required for adequate model fit, as were direct links from academic self-concept and engagement to achievement change. An alternative model representing the hypothesis that academic self-concept fully mediated the relationships between the forms of negative peer treatment and children's engagement and achievement did not fit the data well.     

Professional beliefs related to the practice of pediatric medicine and school psychology

This article proposes that pediatric medicine and school psychology are complementary fields. Five professional beliefs are reviewed: (a) the importance of classification, (b) a preference for evidence-based interventions, (c) an endorsement of advocacy in public policy, (d) the importance of working with the whole child including his/her parents, and (e) an assertion of team leadership. Each belief is discussed as a core value of pediatric medicine and considered for points of connection with school psychology. Some of these beliefs are widely shared by school psychologists, others are rejected because of historical and situational factors, and all warrant consideration in light of school psychology's continuing evolution.     

Processing speed, intelligence, creativity, and school performance: Testing of causal hypotheses using structural equation models

According to mental speed theory of intelligence, the speed of information processing constitutes an important basis for cognitive abilities. However, the question, how mental speed relates to real world criteria, like school, academic, or job performance, is still unanswered. The aim of the study is to test an indirect speed-factor model in comparison to rivaling models explaining the relationships between different mental abilities and performance. In this speed-factor model, basic cognitive processing is assumed to influence higher mental abilities (IQ and creativity). Intelligence and creativity themselves should be valid predictors of school performance. We computed bivariate correlations and structural equation models to test this hypothesis, using indicators of processing speed [Zahlen-Verbindungs-Test (ZVT) and Coding Test], psychometric intelligence [Kognitiver Fähigkeits-Test (KFT) and Raven's Advanced Progressive Matrices (APM)], creativity [Verbaler Kreativitäts-Test (VKT) and Verwendungs-Test (VWT)] and school performance (grades). In a sample of 271 students from German gymnasiums (Class Levels 9 to 11) the speed-factor model can reproduce at best the empirical relationships between processing speed, intelligence, creativity, and school performance: It assumes that processing speed influences higher mental abilities (intelligence and creativity), which, in the sequel, influence school performance. Therefore, processing speed seems to have no direct effect on school performance; the effect is indirect as it operates via mediation through higher cognitive abilities.     

学业受挫大学生上网状况研究

对学业受挫大学生和普通大学生上网行为进行了调查和比较,结果表明:过度使用网络是导致大学生学业成绩下降的重要因素之一,且学业受挫学生的病理性网络使用行为较普通学生严重,强调高校应采取相应措施,防止过度使用网络行为在高校蔓延,并对学业受挫学生上网行为的教育和管理提出了若干对策.     

中学生学业负担态度量表的编制

中小学生学业负担过重是长期以来中国基础教育中特有的问题。本文就“中学生学业负担态度量表”的编制过程及其量表评价结果做一报告。该量表分为认知、情绪和行为三个分量表,测验项目具有适当的通俗度和较高的区分度。通过对三个分量表的因素分析获得了它们各自的主要构成因素。分量表及其各因素具有较高的同质性信度,它们对学生的学业成就具有较高的鉴别力。     

中学生偶像崇拜与自我概念的关系研究

研究采用访谈法和问卷法．选取北京市428名中学生,考察偶像崇拜与自我概念的关系。研究发现：(1)有偶像的学生人数显著高于无偶像的人数,“歌星影星”与“著名人士”是其崇拜的主流。(2)有偶像的学生的自我概念显著高于无偶像的学生,主要在同性关系自我、异性关系自我、非学业自我概念上存在显著差异。(3)在有无偶像维度上,女生的同性关系自我、一般学校自我概念存在显著差异,男生的同性关系自我、一般自我、非学业自我和量表总分存在显著差异。(4)在有无偶像维度上,初一学生的体能自我、初二学生的数学自我、初三学生的语文自我和同性关系自我、高一学生的外貌自我存在显著差异。(5)不同偶像类型的学生的自我概念存在显著差异。     

720名中学生自我同一性地位研究

对中学生自我同一性实证研究表明,中学生自我同一性发展经由一个理慰朦胧——困惑疑为——现实提升的过程。中学生自我同一性地位度数分布中间大,两头小。中学生自我同一性地位存在性别差异。中学生自我同一性地位与学习成效自评交互影响。对中学生自我同一性教育训练应予以重视和加强。     

How semantic categorization influences inhibitory processing in middle-childhood: an Event Related Potentials study

Throughout middle-childhood, inhibitory processes, which underlie many higher order cognitive tasks, are developing. Little is known about how inhibitory processes change as a task becomes conceptually more difficult during these important years. In adults, as Go/NoGo tasks become more difficult there is a systematic decrease in the P3NoGo response, indicating the use of effective inhibitory strategies (Maguire et al., 2009). This paper investigates the age at which children employ similar inhibitory strategies by studying behavioral and Event Related Potential (ERP) measures of response inhibition for three Go/NoGo tasks. Seventeen 7-8 year-olds and twenty 10-11-year-olds completed three Go/NoGo tasks that differed in the level of categorization necessary to respond. Both age groups displayed slower reaction times as the tasks became more difficult. Further, both groups displayed the predicted Go vs. NoGo P3 amplitude differences in the two simplest tasks, but no significant P3 differences for the most complex task. The reason for this pattern of responses was different in the different age groups. Similar to adults in previous work, the oldest children showed an attenuation of the P3 NoGo response with task difficulty, and no corresponding changes in the Go amplitude. The younger children displayed the opposite pattern, a significant increase in the Go amplitude with task difficulty, and no changes in the NoGo response. These response patterns indicate that efficient inhibitory strategies are developing throughout middle-childhood.     

论战国墨家学派发展的四个阶段

依据墨家学说主旨、队伍组织、从事工作,特别是社会作用的不同,可将战国时期墨家学派的发展分为兴盛(公元前444年至公元前381年)、衰败(公元前381年至公元前311年)、转型(公元前311年至公元前250年)、重兴(公元前250年至公元前221年)四个阶段.兴盛阶段,墨家着力游说诸侯、传播学说、制止攻战、助弱国守城;衰败阶段,墨家学派分化内斗,三派弟子活动转型;转型阶段,“谈辩派”后学热衷于空言思辨,“说书派”后学被视为与儒家同类,“从事派”后学对“任侠之风”产生重大影响;重兴阶段,墨家学派声势复盛,“说书派”后学的宣传,“从事派”后学对墨家精神的继承,“谈辩派”后学与儒家、法家的尖锐争辩,都产生了重大社会影响.     

从中亚东干人语言的变迁看文化适应

文化适应是一个描述民族文化关系的重要概念,它指的是两个或两个以上不同文化体系间由于持续接触、相互影响而造成一方或双方发生的大规模文化变迁。本文透过中亚东干人在不同民族文化的接触中其语言变迁的过程,对人类文化适应这一重要的文化现象进行了考察。笔者认为,东干人学习使用范围较广的其他民族语言的事实,不仅表现出其自身较强的文化适应性,而且反映出一种对本民族成员所需社会文化资源和未来发展机会的积极争取。
