本研究采用个别访谈方法对北京海淀区六所幼儿园的60名大班幼儿的母亲进行了访谈，访谈的内容有：（1）母亲对孩子目前在幼儿园的表现满意程度；（2）母亲对幼儿上小学的潜力估计；（3）母亲对幼儿六种 能力的估计；（4）母亲对幼儿的两种个性品质－－毅力和动机的评价；（5）母亲给孩子购买学习资料的情况；（6）母亲对幼儿知识来源的评估。我们按照被访谈母亲的化程度差异，将被调查的母亲分为三类。结果发现：（1）化程度不同的三类母亲对幼儿目前在幼儿园的表现满意程度没有差异。（2）三类母亲对孩子的能力评估差异显。（3）三类母亲给孩子购买学习资料方面差异显。（4）三类母亲对幼儿坚持做一件事的毅力评估得分差异显。     

Old friends, new friends: predictors of children's perspective on their friends at school

Predictors of 5-year-old kindergartners' insights into their friends, and their accounts of liking and conflict with their friends were investigated, with a focus on both the children's and their friends' social understanding during the preschool period, and the quality of their preschool friendships. Seventy children initially studied at 4 years utilizing social cognition tasks and observations of dyadic play with their friends were followed over the transition to school; at school they were interviewed about their friendships and their social understanding was assessed. One group had remained close to their preschool friends, whereas a second group had formed new friendships. Social understanding, language abilities, and prosocial characteristics of both the children and preschool friends, their successful communication and shared pretend play experiences during the preschool period, and their mothers' educational level were related to their perspectives on their current school friends. Liking of current friends was linked to relationship history and maternal educational level for both those with old and with new friends, whereas insight was related to assessments of social cognition.     

High School Students’ Informal Reasoning Regarding a Socio‐scientific Issue,with Relation to Scientific Epistemological Beliefs and Cognitive Structures

This study investigated the relationship among 68 high school students’ scientific epistemological beliefs (SEBs), cognitive structures regarding nuclear power usage, and their informal reasoning regarding this issue. Moreover, the ability of students’ SEBs as well as their cognitive structures for predicting their informal reasoning regarding this issue was also examined. The participants’ SEBs were assessed with a quantitative instrument; their cognitive structures were assessed through tape‐recorded interviews and were further analyzed with the ‘flow map method’; their reasoning regarding nuclear power usage was assessed with an open‐ended questionnaire; and, then, their responses were analyzed both qualitatively and quantitatively. It was revealed that students’ beliefs about the justification of scientific knowledge (an aspect of the beliefs on the nature of knowing science) were significantly correlated with their reasoning quality; the extent and the richness of students’ cognitive structures as well as their usage of the information processing mode, ‘comparing,’ were positively correlated with their reasoning quality. A series of regression analyses further confirmed that students’ use of the information processing mode, ‘comparing,’ was the most significant factor for predicting reasoning quality, while their beliefs regarding the justification of scientific knowledge was the other important predictor.     

晋宋之际的政局与高门士族的动向

晋宋之际,高门士族的动向以义熙八年为界。此前,他们仍在“门阀政治”的观念下从事政治活动,二刘之争即隐含着高门士族利用时局恢复“门阀政治”的因素在内。义熙八年刘裕独掌大权后。高门士族接受最高统治者权威统治的政治格局,转向关注权力分配。在权力危机面前,部分高门子弟表现出强烈的政治进取心,背离了该阶层历来标榜的“素退”的精神风貌。更重要的是,激化了的权力竞争关系削弱了高门士族在政治上的一致性,从而使“门阀政治”的成立条件彻底丧失。

Relationships of Leadership Style and Burnout to Counselors' Perceptions of their Jobs,Themselves, and their Clients

Professional burnout and factors related to the burnout phenomenon are issues that frequently appear in the current literature. Empirical studies to establish the relationships between perceived burnout and pertinent personal or organizational characteristics are difficult to find, however. This exploratory study sought to investigate relationships between counselors' felt degree of burnout and their perceptions of school leadership style, themselves, their job, and their clients. It was found that leadership style in the school was related to counselor's perceptions of themselves and their jobs, but not to their views of their clients or their own potency. Further, it was found that self-reported burnout was strongly related to counselors' perceptions and that self, job, and clients were all perceived more negatively as burnout increased.     

The link between basing self-worth on academics and student performance depends on domain identification and academic setting

Two studies showed that the link between how much students base their self-worth on academics and their math performance depends on whether their identification with math was statistically controlled and whether the task measured ability or not. Study 1 showed that, when math identification was uncontrolled and the task was ability-diagnostic, basing self-worth on academics was unrelated to the students' math performance. When math identification was controlled, however, the more students based self-worth on academics the worse their math performance. Study 2 showed that, when math identification was uncontrolled and the task was ability non-diagnostic, the more students based self-worth on academics the better their math performance. When math identification was controlled, however, students' level of basing self-worth on academics was unrelated to math performance. These results held for females and males even when gender was made salient. In both studies, higher math identification linked to better math performance.

学前儿童情绪表征认知发展的实验研究

通过故事叙述并辅以图片展示的形式，考察了72名3～5岁儿童理解人的外在情绪表现与其内在心理状态的关系。结果显示：3～5岁儿童对外在情绪表现与内在心理体验间关系的理解没有年龄差异，都还没有真正把握外在情绪表现和内在心理体验复杂关系的实质；3～5岁儿童对复杂性不同的外在情绪表征与内在心理感受不一致的情境的认识也不同，3～5岁儿童对情绪表征问题的理解性别差异不显著。
