蒙语词汇识别中语音自动激活的ERP研究

采用快速掩蔽启动范式、Go/No-go范式和事件相关电位（ERP）技术,探讨蒙语词汇识别过程中语音自动激活的时程及对语义通达的作用。实验中要求被试执行一个额外的语义分类任务,对关键刺激不做明显的行为反应。结果发现,SOA为67ms时,语音启动在头皮的额区诱发了明显的P150和N400成分;SOA为167ms时,语音启动在头皮的额区和中央区诱发了明显的P200成分,在整个大脑皮层诱发了明显的N400成分。结果表明,语音在蒙语词汇识别的早期自动激活并促进语义的通达。     

A Cognitive Anatomy of Political Trust and Respective Bases: Evidence from a Two‐City Survey in China

Building on contemporary research on social cognition and psychology, trust, political representation and accountability, and candidate evaluation, this article proposes to decompose political trust into two cognitively distinct but related components for examination: competence versus intention evaluations. This article further argues that people's evaluations of their government's competence and intention in governance can have distinct bases due to the varying accessibility of pertinent information. Using valid instruments from a unique sampling survey in two Chinese cities in 2005, this article tests the validity of this cognitive scheme. Empirical evidence shows that (1) the surveyed Chinese urban residents effectively differentiated between their central government's competence and intention in governance: on average, they had a quite positive assessment of the central government's intention to serve its people, despite their relatively pessimistic views of its competence to deliver good governance; (2) the Chinese urbanites did consult different sources of information and heuristics when evaluating their central government's competence and intention, respectively.     

议程与习惯性反应对学习时间分配的影响：来自眼动的证据

采用眼动记录技术,操作三种词对位置,探讨议程与习惯性反应对学习时间分配的影响。实验一设置无时间限制条件,结果发现,20名大学生被试均优先选择左边的项目,项目的自定步调学习时间不存在词对位置效应。结果表明,被试的习惯性反应影响项目选择,不影响自定步调学习时间。实验二设置有时间限制条件,结果发现,20名大学生被试均优先选择容易项目并分配更多的时间学习容易项目,且容易项目的选择存在词对位置效应。结果表明,议程驱动主导被试的项目选择和自定步调学习时间,但不能完全消除习惯性反应对项目选择的影响。     

301例中枢神经系统感染的临床分析

回顾性研究301例中枢神经系统感染病例的临床资料,分析其临床特点,将符合临床诊断标准的病例按病原种类分为病脑组、结脑组、化脑组及隐脑组4个组,应用相关的统计描述分析其临床特征。结果发现病毒性脑（膜）炎是最常见的中枢神经系统感染性疾病,而中枢神经系统感染性疾病一年四季均可发病,其中病毒性脑（膜）炎高发于5月及7月,结核性脑膜炎则高发于1月与3月,有明显的季节性。中枢神经系统感染的临床首发症状依次表现为发热、头痛、意识障碍、精神症状、抽搐及神经系统定位症状。     

抽象概念表征的具身认知观

抽象概念是否通过感知经验来表征以及如何被感知经验表征是具身认知面临的一大问题.在抽象概念表征是否具有感知经验基础的问题上,具身认知理论认为抽象概念通过情境模拟或隐喻与感知经验发生联系.在抽象概念如何与感知经验表征发生联系的问题上,概念模拟理论强调情景或运动模拟在抽象概念表征中的直接作用;概念隐喻理论则侧重具体经验或具体经验与抽象概念之间的共同结构关系在抽象概念表征中的间接作用.未来研究应改变概念表征的稳定的心理实体观,从语言和抽象表征的关系、正常儿童和特殊群体的抽象概念表征差异入手,整合不同的具身认知观点.     

临床药师问诊与实践体会

问诊是临床医师的基本技能之一.医师通过问诊可以获得病史资料,从而做出临床决策.随着医学模式从传统的生物医学模式向生物心理社会医学模式转变和临床药学的蓬勃发展,药学服务模式从传统的以保障药品供应为中心向以患者为中心模式转变.药师从药房逐步走向临床,参与合理用药和提供药学服务,问诊也应成为临床药师的基本技能之一.本文通过笔者问诊实践,阐述问诊对于临床药师的重要性、药师问诊的内容及其与医生问诊的区别.     

社会阶层分化视角下医患信息行为对医患关系的影响

目前社会阶层分化进程中的医患关系比较紧张,医患信息行为起了很大作用.由于历史原因多数医师未能认识到医患信息行为对医患沟通及医患关系的影响.患者作为医疗信息掌握的弱势群体,其对从医师处获得信息的依赖将长期存在,医师与患者信息行为必然相互影响.针对信息行为建立相应的培训及评价机制是十分必要的.     

“治未病”理念对减少宫颈癌发生的影响及策略

分析传统医学“治未病”的思想原则,从来病先防,既病防变,愈后防复三方面探讨“治未病”理念对减少宫颈癌的发生、发展及治疗的影响.只要将“治未病”理念贯穿于宫颈癌的防治中,加强全社会育龄妇女对宫颈癌的预防保健意识,认真执行宫颈癌普查的程序,对降低宫颈癌的发病率和死亡率具有切实意义.     

Attention can operate on semantic objects defined by individual Chinese characters

Attention can select perceptual objects, but it is less clear whether attention can operate on objects defined by higher level cognition, such as semantic associations. Recent studies have shown that attention may be based on objects defined by Chinese two-character compound words, suggesting that attention can operate on semantic objects. In the present study, object-based attention (OBA) effect was investigated at the level of individual Chinese characters, and the role of character structure and radical order in OBA was explored by using a spatial cueing paradigm. In Experiment 1, we found OBA effect for conditions that had legal radical order, but not for other conditions in which the radical order information was disrupted. Character structure, however, had no influence on the OBA effect. In Experiment 2, we observed OBA effect for all conditions after enhancing the radical order and character structure information by adding perceptual cues. The results extend previous findings of a “semantic object”-based attention effect from the two-character word level to the individual character level. Moreover, we found that radical order but not character structure was important for this semantic OBA effect. We conclude that visual attention can be based on semantic objects at the level of individual characters, and that the development of semantic objects is affected by the perceptual grouping of the radicals.     

The dissemination and research of Laszlo's systems philosophy in China

Since the 1980s, the so‐called “new six‐theory” (Dissipative structure theory, Synergetics theory, Catastrophe theory, Chaos theory, Fractal theory, and Hypercycle theory), different from the traditional “systems theory,” “information theory,” and “cybernetics theory” (the “old three theory") has been introduced into China. With it, Laszlo's systems philosophy has been given close attention by Chinese scholars. The main elements of this work are analyzed in terms of the publication and research of Laszlo's work on systems philosophy, and more specifically on systems philosophy and the theory of knowledge, systems philosophy and general evolution theory, systems philosophy and the theory of value, and systems philosophy and metaphysics.
