The neural basis of insight problem solving: an event-related potential study

The electrophysiological correlates of successful insight problem solving (Chinese logogriphs) were studied in 18 healthy subjects using high-density event-related potentials (ERPs). A new experimental paradigm (learning-testing model) was adopted in order to make subjects find a solution on their own initiative rather than receive an answer passively. Results showed that Successful guessed logogriphs elicited a more positive ERP deflection (P200-600) than did Unsuccessful guessed logogriphs in the time window from 200 to 600 ms after onset of the stimuli. Subsequently Successful logogriphs elicited a more negative ERP deflection than did Unsuccessful logogriphs in the time windows of 1500-2000 ms (N1500-2000) and 2000-2500 ms (N2000-2500). Maps of the P200-600 showed strong activity in the midline parieto-occipital scalp regions. Dipole analysis localized the generator of P200-600 in the left superior temporal gyrus and parietotemporo-occipital cortex areas. The N1500-2000 and N2000-2500 had a distinct activation over left frontal scalp regions. Dipole analysis localized the generator of the N1500-2000 in the anterior cingulate cortex (ACC) and the N2000-2500 in the posterior cingulate cortex (PCC). This result indicates that the parietotemporo-occipital cortex areas might be involved in forming rich associations in the early stage of successful logogriph solving. Then, the ACC might play an important role in the breaking mental set and the forming of novel associations. At last, "Aha" feeling might activate the PCC.     

A Comparison of the Common‐Item and Random‐Groups Equating Designs Using Empirical Data

We designed this study to evaluate several data collection and equating designs in the context of item response theory (IRT) equating. The random‐groups design and the common‐item design have been widely used for collecting data for IRT equating. In this study, we investigated four equating methods based upon these two data collection designs, using empirical data from a number of different testing programs. When the randomly equivalent group assumption was reasonably met, the four equating methods tended to produce highly comparable results. On the other hand, equating methods based upon either of the equating designs produced dissimilar results. Sample size can have differential effects on the equating results produced by the different equating methods. In practice, a common‐item equivalent‐groups design often produces unacceptably large differences in the group mean due to various anomalies such as context effects, poor quality of common items, or a very small number of common items. In such cases, a random‐groups design would produce more stable equating results.     

《资本论》的哲学意义

如何看待马克思《资本论》的哲学意义?这是一个迄今为止远未完全解决的重大问题。在国内外学术界中,有两种较为流行的理论观点:一种观点认为,《资本论》只是政治经济学著作,马克思一生只是一个经济学家,马克思《资本论》谈不上有什么特殊的、重大的哲学意义,大多数西方经济学著     

3—7岁儿童与成人筷子使用动作模式的比较研究

通过比较3—7岁儿童与成人的筷子使用动作模式类型、特征和使用率,初步探讨了筷子使用动作模式的特点及发展趋势。研究结果表明：(1)儿童与成人中均存在八种筷子使用动作模式,各种模式在手指的分工、配合及完成任务的稳定性、适应性等方面表现出不同的特点,具有不同的效率水平;(2)随年龄的增长,个体筷子使用动作模式日趋转向效率较高的类型,表现为高效模式的使用率从3岁组的3．7％增加到成人组的50％,而低效模式的使用率从59．3％下降到10％。     

Culture in the Mediation of International Disputes

Unlike most treatments of culture in international diplomacy, this article suggests that culture can play a positive role in the mediation of international disputes. Cultural ties between the mediator and one or both of the disputants can facilitate mediation by, among other things, enhancing the mediator's acceptability to the parties, and enhancing the belief that the mediator can deliver concessions and agreements. Moreover, a mediator who is closer to one side than the other can be effective in mediation, especially when the mediator acts in an even‐handed manner. Data from laboratory research on mediation, as well as anecdotal evidence, support this view.     

A test of theory of planned behavior in Korea: participation in alcohol-related social gatherings

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral outcomes or different assessments of the same behavioral outcomes.     

What can I gain as a mentor? The effect of mentoring on the job performance and social status of mentors in China

In this study, we examine how mentoring benefits mentors as well as how team cohesiveness affects mentoring relationships and resulting benefits. We followed 512 formal mentors in a Chinese manufacturing firm for six months and collected data in three phases and from three sources. The findings reveal that the amount of mentoring provided is positively related to mentors' in‐role job performance and social status. These relationships were fully mediated by mentors' personal learning and social interaction quality, respectively. Team cohesiveness, however, did not moderate these relationships. Our empirical findings have implications for understanding how mentors' careers can benefit from being a mentor.

组织行为学研究的现状：意义与建议

本文对2008~2011年这4个年度发表在英文和中文组织行为学方面重要学术期刊上的研究进行总结, 旨在让国内学者了解现今组织行为学的现状和发展。我们在分析研究内容、研究方法的基础上, 就当前中国组织行为学研究提出了一些总结性的看法, 包括：研究问题很大程度上追随国际潮流, 但缺乏对本土重要问题的关注; 研究方法过多地集中于定量的问卷调查法, 但缺乏对多种不同方法的应用; 研究的分析层次过多地集中在个体层次上, 而对多层次的组织和团队管理现象关注不足。为更好地促进组织行为学科的发展, 本文建议：应该注重立足中国的组织和管理现象来挖掘研究问题; 采用多种研究方法, 特别应鼓励开展定性研究; 注重跨层次研究和研究的情境化等。本文通过介绍近年来组织行为领域的全面情况并详细分析其中的若干个例, 为如何克服以上不足提供具体的范例和方法。
