ERP evidence for the time course of graphic, phonological, and semantic information in Chinese meaning and pronunciation decisions

Two words that varied in their relationship were presented sequentially to Chinese readers who made meaning and pronunciation decisions. In the meaning task, they decided whether the words had the same meaning. In the pronunciation task, they decided whether the words had the same pronunciation. In both tasks, the word pairs represented 1 of 4 relationships: graphically similar, homophonic, semantically related, or unrelated. Event related potentials (ERP) recordings made from the onset of the 2nd word suggested a temporal unfolding of graphic, phonological, and semantic effects. Specifically, graphically-related pairs produced a smaller P200 in the pronunciation task and a smaller N400 in the meaning task. Homophones produced reduced N400 component with bilateral sources in the meaning task.

辩证分析兴奋性氨基酸对神经细胞的双重作用

兴奋性氨基酸（ＥＡＡｓ） 广泛分布于中枢神经系统,参与多种生理过程包括学习、记忆和伤害感受等。然而,ＥＡＡｓ 受体的过度兴奋却可引发一系列细胞事件,最终导致神经元的损伤与死亡。许多神经退行性疾病如早老性痴呆、癫痫和肌侧索硬化症等都与ＥＡＡｓ 的兴奋毒作用有关。目前的研究表明,由ＥＡＡｓ 受体过度兴奋所引发的细胞内钙超载是导致神经元死亡的最终途径     

《周易正义》的刑罚适用原则探源

在严格区别《周易》、王弼《周易注》及《周易正义》三者不同思想的基础上,厘清《周易正义》所蕴含的法律思想是《周易正义》法律视角研究的当务之急。作为《周易正义》法律思想的表征体系,《周易正义》中的刑罚适用原则可简述为:区分故意与过失原则、轻刑原则、重刑原则。这些原则的形成有其特定的哲学基础。     

组织变革背景下团队主动性的结构与测量

旨在探索组织变革背景下团队主动性行为的结构,并开发出相应的测量工具。首先对20家企业的27位高管进行了深度访谈,然后按照扎根理论思路对获取资料进行细致分析,探索团队主动性的结构,再按照严格的心理测量学程序开发团队主动性的测量问卷,并以来自60家企业的70个团队（共292位成员）为对象进行了测验。研究发现：团队主动性的主要维度包括群策、协作和适应。经过探索性因素分析和验证性因素分析,结果表明测量工具有着良好的信度和构思效度。     

The impact of associative strength on performance in goal pursuit

The present research explored the hypothesis that strengthened attainment means–goal association leads to enhanced performance in goal pursuit. We hypothesize that because of the instrumental nature of means–goal association, strengthened associative strength leads to greater instrumentality expectancy of the means, which elicits greater motivation in the pursuit and hence better actual performance. We demonstrated in four studies that when the means is believed to facilitate goal attainment, a strong (vs. weak) means–goal association leads to greater performance in goal pursuit. Conversely, when the means is perceived to undermine goal attainment, a strong (vs. weak) association results in worse performance in goal pursuit.     

The effect of food toppings on calorie estimation and consumption

In this research we examine the effect of adding a food topping to the base food on consumers' calorie estimation and consumption of the augmented food (base food plus topping). We show that consumers underestimate the calorie content of augmented food with an unhealthy base, especially when the topping is healthy. However, consumers are less likely to underestimate the calorie content of augmented food with a healthy base, regardless of whether the topping is healthy or unhealthy. Further, we show that adding a healthy topping to an unhealthy base makes consumers not only underestimate the calorie content but also eat more of the augmented food.     

马克思的社会形态思想再探——基于《政治经济学批判〈序言〉》中社会经济形态演进论述的分析

作为历史唯物主义的重要内容,社会形态思想是对社会历史的形成、发展及其运动的内在规律的深刻揭示和整体阐发,正确把握社会形态思想中的社会历史分期和演进的规律具有十分重要的意义。本文通过对学界关于《政治经济学批判〈序言〉》中社会经济形态演进论述的理解所形成的“三形态说”和“五形态说”争论的梳理和辨析,进一步探讨马克思的社会形态思想,认为马克思在《政治经济学批判〈序言〉》中的相关论述既指出了社会形态演进的基础和发展方向,又隐含着一定社会历史中人的发展状态的内容,同时内蕴分析社会形态的基本原则。

父母严苛型教养方式与青少年自杀倾向:一个有调节的中介模型

在对西安市四所中学4071名中学生进行问卷调查的基础上,实证研究了父母严苛型教养方式与青少年自杀倾向之间的关系。结果表明:(1)从直接效应上讲,父母严苛型教养方式和个体自身对自杀行为的合理化认知对青少年自杀倾向具有显著的正向预测作用;(2)青少年对自杀行为的合理化认知在父母严苛型教养方式和自杀倾向的相关关系中起部分中介作用;(3)在严苛型教养方式通过自杀行为合理化认知影响自杀倾向的模型中,同伴支持变量不存在显著的调节作用,而教师支持变量在这一模型的直接路径与中介模型后半段均起调节作用。
