结构、任务类型和导航对超文本信息搜索的影响

通过两个实验考察了结构、任务类型和导航对超文本信息搜索绩效的影响。实验一采用2（层次结构,混合结构）×2（特定任务,关系任务）的被试内设计,探讨了超文本结构和任务类型对信息搜索的影响;实验二在实验一的基础上,采用2（层次结构,混合结构）×2（有导航图,无导航图）的被试内设计,考察超文本结构和导航对关系任务信息搜索的影响。结果表明：（1）超文本结构和任务类型对信息搜索绩效有显著的交互影响,就关系任务而言,混合结构超文本优于层次结构超文本,但就特定任务而言,两者无显著差异;（2）导航对信息搜索行为有指导作用,尤其对层次结构超文本有利;（3）两种主观指标的结果与客观指标存在一定程度的一致性。     

论科学精神的构成

科学精神是人们从科学活动过程中及科学认识成果中提炼出来的价值准则和行为规范,是人的认识精神在科学认识上的投影,是人类在漫长而艰巨的科学研究探索的过程中逐渐形成并不断发展起来的一种主观的精神状态。江泽民同志说:“科学精神的内涵很丰富,最基本的要求是求真务实,开拓     

当代道德教育指向:从道德顺从到道德选择的理路

我国的道德教育有着悠久的历史,其主体流质是道德顺从教育,原因有:伦理本位的思想传统;群体本位的教育倾向和道德教育的政治统治功能强化。当代道德教育的时代背景的变迁即社会结构的转型和多元化社会的形成以及当代道德教育人本倾向和生活世界的实践回归,标示着道德选择教育成为了道德教育的内在要求和指向。     

Be loyal but not addicted: Effect of online game social migration on game loyalty and addiction

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

Traumatic Exposure and Psychological Well-Being: The Moderating Role of Cognitive Flexibility

This study examined the moderating role of cognitive flexibility between earthquake exposure and psychological well-being. The participants were 491 adolescents from three middle schools in Sichuan. Multivariable, hierarchical linear regressions were used to analyze the data. The findings showed that there were significant differences in psychological well-being for the dimension of relocation of school (T = ?3.09, p < 0.01), damage to property (F = 2.73, p < 0.05) and damage to school (F = 5.76, p < 0.01). Hierarchical regression analysis indicated that cognitive flexibility moderated the relation between being hurt during the earthquake and psychological well-being (B = 1.01, SE = 0.31, T = 3.22, p < 0.01).     

类别变量的中介效应分析

在心理学和其他社科研究领域,研究者能熟练地进行连续变量的中介效应分析,但面对自变量、中介变量或(和)因变量为类别变量的中介效应分析,研究者往往束手无策。在阐述类别自变量中介分析方法的基础上,我们建议使用整体和相对中介相结合的类别自变量中介分析方法,并给出了分析流程。以二分因变量为例,讨论了中介变量或(和)因变量为类别变量的中介分析方法的发展过程(即尺度统一的过程),建议通过检验Za×Zb的显著性来判断中介效应的显著性。用二个实际例子演示如何进行类别变量的中介效应分析。最后展望了类别变量的中介效应分析研究的拓展方向。     

Down but not out: Newcomers can compensate for low vertical access with strong horizontal ties and favorable core self‐evaluations

We draw upon and extend socialization resources theory to explain how organizational newcomers leverage their social capital resources (i.e., vertical access and horizontal tie strength within their communication networks) and personal resources (i.e., core self‐evaluations) to learn about and assimilate into their work and organizations. The findings of a multiwave study of organizational entrants in China reveal the synergistic effects of relational and personal resources for newcomer adjustment. Newcomers learn and assimilate effectively not only when they have vertical connections to high‐status organization members but also when they can compensate for their lack of high‐status connections by leveraging their strong horizontal ties with peers and favorable core self‐evaluations. These findings provide a practical perspective on how to tailor newcomer onboarding practices to facilitate effective newcomer adjustment.     

Olfaction is a Marker of Severity but Not Diagnosis in Anorexia Nervosa: a Systematic Review and Meta-Analysis

Neuropsychology Review - Researchers have examined if olfaction is a sensitive biomarker of anorexia nervosa, but considerable heterogeneity across studies makes it difficult to reach a consensus....     

结合选择题与主观题信息的两阶段作弊甄别方法

为提高对高分作弊者和低抄袭比例作弊者的检验力,模拟600名考生的作答,设置3种抄袭比例（60%,80%和100%）和3种抄袭源能力（能力百分等级为60%,80%和100%）,设计两阶段作弊甄别法,第一阶段使用lz指数筛选个人拟合差的异常考生,第二阶段针对这些异常考生使用ω指数进行精确甄别。结果表明该法对高分作弊者和低抄袭比例作弊者的检验力优于仅使用答案抄袭检测法。     

童年期虐待对网络成瘾的影响:有调节的中介效应

本研究基于有限自制力理论考察童年期虐待对网络成瘾的影响及其作用机制。以1162名大学生为被试,采用童年期虐待量表、自我控制量表、感恩量表和网络成瘾量表进行测试,结果发现：（1）童年期虐待和自我控制、感恩呈显著负相关,与网络成瘾成显著正相关;自我控制与感恩呈显著正相关,与网络成瘾呈显著负相关;感恩与网络成瘾呈显著负相关。（2）自我控制在童年期虐待和网络成瘾之间起中介作用。（3）“童年期虐待→自我控制→网络成瘾”这一中介路径的前半段受到感恩的调节;与高感恩个体相比,童年期虐待对低感恩个体的自我控制的影响更小。感恩不仅不能缓冲童年期虐待对自我控制的负面影响,反而会增强这一过程,提示我们注意积极特质在特定情境下的消极作用。
