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.     

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。     

中学生职业兴趣的结构及其特点

参考国内外有关资料,设计适合我国中学生的职业兴趣测验。对309名在校中学生测查结果的因素分析表明,共存在六个因素,可以解释为现实型（R)、研究型 (I)、艺术型 (A)、社会型 (S)、经营型 (E)和常规型(C),这与霍兰德的六种职业类型一致。但六种兴趣之间的关系与霍兰德的职业六边形不完全一致。进一步的分析表明,初三以上的中学生的职业兴趣已出现明显分化。年级和性别因素对职业兴趣均有显著影响,年级与性别的交互作用不显著。     

Child Characteristics,Parent Education and Depressive Symptoms,and Marital Conflict Predicting Trajectories of Parenting Behavior from Childhood Through Early Adolescence in Taiwan

The study examined how child and parent characteristics, and contextual sources of stress, such as marital conflict predict initial status and trajectories of parent involvement, support, and harsh control, over a 4‐year period in families in Taiwan (n = 4,754). Based on Belsky's (1984) ecological model of parenting, three domains predicting parenting were tested, child characteristics (age cohort and gender), father and mother characteristics (education and depressive symptoms), and contextual sources of stress (marital conflict). The study followed two cohorts of children; the younger cohort was followed from first to fourth grade and the older cohort from fourth to seventh grade. Initially, fourth graders reported more parental involvement, support, and harsh control than first graders. However, involvement, support, and harsh control decreased across the 4 years for the older cohort as they transitioned to early adolescence. In the first year, girls reported more parental involvement and support and less harsh control than boys. Across the 4 years, involvement and support increased, and harsh control decreased for boys; whereas involvement stayed the same, support slightly decreased, and harsh control slightly increased for girls. Children whose parents were more educated reported more parent involvement, support, and harsh control in the first year. Children whose fathers were chronically depressed and whose parents were experiencing marital conflict reported decreasing parent involvement and support over the years.     

Childhood antecedents of Agreeableness: A longitudinal study from preschool to late adolescence

Although the consensus view is that Agreeableness originates from childhood difficultness and regulatory deficits, few studies have investigated such assumptions longitudinally. In this study, we examined this issue by assessing enduring and mediating effects of self-regulation as well as the impact of parenting behaviors on the development of Agreeableness from preschool to late adolescence. Longitudinal data from 965 Norwegian families following children from 1.5 years to 16.5 years were used. Path analyses revealed childhood difficultness at age 4 to be related to Agreeableness at age 16.5; this effect was mediated through emotion regulation in late childhood. However, such mediation effects were primarily found when parents used punitive practices towards their children. Our findings point to personality coherence throughout development.     

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。     

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。     

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。     

The vocational well-being of workers with childhood onset of disability: Life satisfaction and perceived workplace discrimination

Workers with disabilities are understudied, and workers with childhood onset of disability have been excluded from many of the studies on disability and work that do exist. This research compares the effects of childhood and adult onset of disability in a nationally representative sample of workers with disabilities. Educational disruptions due to disability status in childhood are negatively associated with life satisfaction and positively associated with perceived discrimination. Although age is associated with increased life satisfaction and decreased perceptions of discrimination for workers with adult disability onset, age is unrelated to these outcomes for workers with childhood disability onset. Receiving workplace accommodations is positively associated with satisfaction and negatively associated with discrimination for both groups, however, these relationships are stronger in magnitude for the childhood disability onset group. Organizational environments, both in education and in the workplace, play a critical role in the vocational well-being of workers with childhood disability onset.
