学前和小学低段不同识字量儿童的认知能力比较

以193名学前儿童和291名一到三年级小学生为研究对象, 比较了不同年级、不同识字量儿童在语音意识、语素意识、快速命名、视觉技能和正字法意识方面的差异。结果显示, 不同年级、不同识字量儿童分别在语音意识和语素意识的不同层面存在差异, 学前主要表现在音节删除和语素建构任务中, 小学阶段表现在韵母识别、音位删除以及语素判断和语素产生方面;快速命名能力是区分各阶段儿童汉字识别能力的有效指标, 学前儿童的视觉能力与识字量密切相关, 而小学儿童的正字法意识与识字量密切相关。     

Loneliness among school-aged children and their parents

The aim of this study was to examine the existence of the intergenerational transmission of loneliness between parents and children, including an examination of its stability and of gender differences. The study consisted of an evaluation of loneliness in mothers ( n = 834), fathers ( n = 661) and their 10-year-old children ( n = 981). Parent's self-reported loneliness was measured once, and their children's social and emotional loneliness were assessed at three time-points. The stability analysis indicated average stability in children's loneliness, especially their social loneliness. Boys were found to experience more emotional loneliness than girls. Structural equation modeling indicated no direct relationship between mothers'/fathers' loneliness and their children's loneliness. However, mothers' and fathers' loneliness reduced their daughters' peer-evaluated cooperating skills, which consequently predicted higher levels of both social and emotional loneliness.     

Negative self-evaluations and the relation to performance level in socially anxious children and adolescents

The current study investigated whether negatively biased self-evaluations of nervousness and social skills are related to how well an individual actually performs, that is performance level. Sixty-eight high socially anxious and 68 control participants (age range 9–17 years) gave a 5 min speech in front of a pre-recorded audience of same age peers and a teacher. Participants' evaluations immediately after the task were measured on a number of performance dimensions. Three independent observers also evaluated recordings of the speech performances. Participants were further divided into good and bad performers based on their actual performance level as judged by the observers. Self-evaluations of the high socially anxious participants were negatively biased for nervous appearance regardless of how well they actually performed. In contrast, a negative bias for social skills only occurred in the high anxious participants with a good performance. The social skill evaluations of the poor performers appear warranted. Taking actual performance level into account may help to clarify the exact nature of a negative bias in socially anxious youth and has clear implications for the choice of treatment approach.     

Changes in brain activation induced by the training of hypothesis generation skills: an fMRI study

The aim of the present study is to investigate the learning-related changes in brain activation induced by the training of hypothesis generation skills regarding biological phenomena. Eighteen undergraduate participants were scanned twice with functional magnetic resonance imaging (fMRI) before and after training over a period of 2 months. The experimental group underwent eight biological hypothesis generation training programs, but the control group was not given any during the 2-month period. The results showed that the left frontal gyri, the cingulate gyrus, and the cuneus were activated during hypothesis generation. In addition, the brain activation of the trained group increased in the left inferior and the superior frontal gyri, which are related to working memory load and higher-order inferential processes. However, the activation after training decreased in the occipito-parietal route, which is associated with the perception and the analysis processes of visual information. Furthermore, the results have suggested that the dorsolateral prefrontal cortex (DLPFC) region is the critical area in the training of hypothesis generation skills.     

Sibling Conflict Resolution Skills: Assessment and Training

Sibling conflict can rise to the level of a clinical problem. In Phase 1 a lengthy behavioral role-play analog sampling child reactions to normal sibling conflicts was successfully shortened. In Phase 2 normal children who lacked sibling conflict resolution skills were randomly assigned to a Training or Measurement Only condition. Training consisted of five clinic sessions focusing on verbal reasoning, assertiveness, and acceptance skills. Trained children outperformed Measurement Only children on the shortened role-play test. Parents of trained children, but not untrained children, perceived improved social competence in the home. The project provides an empirical foundation for future research with aggressive siblings.     

Improving the Social-Behavioral Adjustment of Adolescents: The Effectiveness of a Social Skills Group Intervention

We evaluated the efficacy of a social skills training intervention designed to improve adolescents’ social, emotional and behavioral adjustment, Social Skills Group Intervention-Adolescent (S.S.GRIN-A). Seventy-four adolescents (ages 13–16 years) and their parents were randomly assigned to either the treatment group (N = 40) or a wait-list control group (N = 34). Adolescents in the treatment and control groups were compared on global self-concept, social self-efficacy, internalizing problems, and externalizing problems pre- and post-intervention. Youth in the treatment group demonstrated enhanced global self-concept, increased social self-efficacy, and decreased internalizing problems as compared to youth in the control group. No differences in externalizing behavior were found. We discuss the effectiveness of S.S.GRIN-A as a general program designed for addressing a range of adjustment issues and social skill deficits in adolescents.     

义符熟悉性对高频形声字词汇通达的影响

采用启动词汇判断范式,考察义符熟悉性对高频汉字形声字认知的影响。结果表明,义符加工与整字加工存在动态的交互作用。在加工早期,高频汉字形声字的整字语义已经激活,但此时义符的语义并未激活。高熟悉性义符的词形启动比低熟悉性义符早。随着SOA增长,高、低熟悉性义符的语义都出现激活。到了加工晚期,汉字形声字整字的语义激活仍然显著,但义符的语义激活消失,表明字词认知的整合过程已经完成。这一结果支持汉字认知中整字加工和部件加工相结合的观点     

团队决策及其影响因素

随着组织结构的变化,团队决策为越来越多的组织所采用。该文将团队决策的研究范式概括为以下四类：社会决策图式（social decision scheme, SDS）、信息取样模型（information sampling model）、项目排序任务（ranking item task）团队以及组织中以安全优先的团队（safety priority team）;并从影响团队决策的因素,提高团队决策质量的策略等角度分别对四类团队决策的研究进行探讨,在此基础上本文对未来研究进行了展望     

Social Anxiety and Peer Relations in Early Adolescence: Behavioral and Cognitive Factors

This study investigated factors associated with social anxiety during early adolescence using multiple informants, including self and peer perspectives, teacher ratings, and direct observations. Negative social performance expectations, maladaptive coping strategies, and social skill deficits were examined as correlates of social anxiety and mediators linking social anxiety with poor peer relations. Participants were 84 middle school students (47 girls, 37 boys) over-sampled for elevated social anxiety. Analyses revealed correlations linking social anxiety with decreased peer acceptance and increased peer victimization. Path analysis indicated that negative social performance expectations and social withdrawal-disengagement accounted for the association between social anxiety and decreased peer acceptance. Social anxiety, self-directed coping strategies, and social withdrawal-disengagement were each directly linked with increased peer victimization for boys. The results replicate findings based on clinical samples, extend understanding of cognitive, social, and behavioral factors associated with social anxiety in middle school, and provide new information regarding gender differences in the correlates of social anxiety.
