概念图对学生成绩和态度影响的元分析

这个元分析评论了学生利用概念图进行学习的实验研究.首先按照元分析的标准选择文章,从涉及3623名被试的26项研究中抽取27个独立效果量.不同年级水平的学生应用概念图学习科学、心理学和统计学等课程的内容.后测评估了知识的唤起和迁移.在不同的教学条件、教学情境和方法中,应用概念图策略都使得学生的成绩增加、学生对学习的态度变得更加积极肯定、降低了学生对学习的焦虑.平均效果量依据概念图的使用方法和对照组的特点而改变,不同的研究存在显著的异质.     

Developmental changes in depressive cognitions: a longitudinal evaluation of the Cognitive Triad Inventory for Children

As part of a longitudinal study, the Cognitive Triad Inventory for Children (CTI-C; N. J. Kaslow, K. D. Stark, B. Printz, R. Livingston, & S. L. Tsai, 1992) as well as other measures of cognitive style and depressive symptoms were administered annually to 3 cohorts of children starting in Grades 2, 4, and 6. Developmentally based analyses revealed 4 things: (a) The factor structure of the CTI-C changed over the course of middle childhood and then stabilized in early adolescence; (b) the CTI-C correlated significantly with measures of depression, self-perceived competence, self-worth, perceived controllability, and perceived contingency, but not with measures of attributional style; (c) 1-year stability correlations increased substantially from Grade 2 to Grade 8; and (d) the CTI-C did not generally predict self-reported depressive symptoms 1 year later. Implications emerge regarding developmental changes in the structure of children's depressive cognitions.     

以唯物史观全面理解"以人为本"

人的问题是改革开放30年来马克思主义哲学研究中的重要问题.近年来,以人为本的科学发展观提出来之后,如何理解"以人为本"成为哲学界的一个热门话题,也出现了不少分歧和争论.有的学者与西方人本主义思想做比较,有的学者同中国古代的民本观做对照,有的学者结合现代管理学中的以人为本观念进行阐释,更多的人认为中国共产党人在当今条件下提出以人为本,尽管也是吸取以往的思想资源和合理因素的结果,但从根本上说,它是共产党为人民服务的宗旨在新形势下的发展和崭新表述,所以只能是以人民为本而不是以作为个体的人为本.也有学者提出,应该把作为"政治理论"的以人为本与作为"学术"的以人为本进行区分,前者就是以人民为本,后者则有着更丰富的内涵.     

Women's eye contact and men's later interest: two field experiments

Previous studies indicated various nonverbal behaviors including eye contact of women are associated with men's approach; however, duration of the eye contact was not tested. In Exp. 1, a female confederate established eye-contact of 3 sec. or 1 sec. with a man when entering a bar. Duration of returned glance was the dependent variable. Analysis showed mean duration of the return glance was statistically shorter in the 1-sec. condition. In Exp. 2, the confederate made eye contact with a man and looked at him less than 1 sec., 2 sec., or 4 sec. The presence versus absence of smile was the dependent variable. Longer duration of eye contact was associated with an increase of smiling.     

3～5岁幼儿在主题-规则冲突条件下的类比推理

本研究采用经典类比任务,考察了3～5岁幼儿在主题-规则冲突条件下类比推理发展的水平与特点.结果表明:(1)在无主题联想条件下,幼儿的单维类比推理在3～4岁迅速发展,4～5岁发展较为平缓,而双维类比推理在3～5岁仍处于较低水平.(2)在主题—规则冲突条件下,幼儿在单维类比推理中表现出一定的主题联想优势反应;幼儿在双维类比推理中表现出较强的主题联想优势反应,年龄特点为:3岁幼儿有较强的主题联想优势反应,4岁幼儿的主题联想优势反应明显下降,而5岁幼儿又表现出较强的主题联想优势反应.     

对建立我国艾滋病防治督导与评估体系的思考

随着我国艾滋病防治工作的持续深入,定期对艾滋病防治工作进行督导与评估越来越重要。但是,到目前为止,我国尚未建立国家综合协调的艾滋病防治督导与评估体系。通过对建立国家艾滋病防治督导评估体系的必要性、可行性及存在的问题进行分析,围绕如何构建一个统一、综合、有效的督导评估体系提出政策建议。     

大学生因特网成瘾障碍的研究

本研究根据目前广泛认可的因特网成瘾障碍(Internet Addiction Disorder,IAD)诊断标准自编问卷,调查了上海市6所高校370名大学生的上网情况。结果表明:(1)自编问卷质量的各指标皆良好,问卷具有较好的稳定性和准确性。(2)上海市大学生IAD的发生率大约为8.1%。(3)男生比女生、理科比文科、大二年级比其它年级的学生陷入网络的程度深。(4)上网者每周的上网时间、使用网络工具的数量、上网动机的数量与使用网络的程度相关。(5)IAD者在网络使用的特点上明显不同于非IAD者(N-IAD者)。     

Contagion or restitution? When bad apples can motivate ethical behavior

When there is a “bad apple” in the group, are we more likely to follow the example or compensate for their sins? Three experiments showed that whether a group member’s unethical actions lead to contagion or restitution depends on the presence of out-group observers. In Experiment 1, participants were more likely to compensate for the transgression of an in-group member than an out-group member when there were out-group observers. Experiment 2 varied the presence of out-group observers and showed that such compensatory behaviors occur only in the presence of out-group members. We suggest that the presence of out-group observers trigger a self-categorization process that induces guilt in individuals for their group members’ transgressions. Indeed, associated guilt mediated the relationship between in-group member’s unethical behavior and participants’ compensatory behavior (Experiment 3). These results suggest that norms implied by others’ behavior and group categorization are important determinants of ethical behavior.     

Induced Reminiscence of Love and Chivalrous Helping

This study tested the effect of semantically-induced thoughts of love on chivalrous helping. A field setting of four hundred and one participants was divided into two groups. One group was interviewed and asked to retrieve the memory of a love episode, and the second group, the control group, was asked to retrieve a piece of music that they love. The two groups encountered another confederate, who inadvertently lost a stack of compact discs when they neared each other. The results demonstrated that participants were more helpful when they were male, when the person in need of help was female, and when they were induced to retrieve the memory of a love episode.
