Correspondence Between Kripke Frames and Projective Geometries

In this paper we show that some orthogeometries, i.e. projective geometries each defined using a ternary collinearity relation and equipped with a binary orthogonality relation, which are extensively studied in mathematics and quantum theory, correspond to Kripke frames, each defined using a binary relation, satisfying a few conditions. To be precise, we will define four special kinds of Kripke frames, namely, geometric frames, irreducible geometric frames, complete geometric frames and quantum Kripke frames; and we will show that they correspond to pure orthogeometries (or, equivalently, projective geometries with pure polarities), irreducible pure orthogeometries, Hilbertian geometries and irreducible Hilbertian geometries, respectively. The discovery of these correspondences raises interesting research topics and will enrich the study of logic.     

人类社会认知的神经机制:来自社会脑研究的证据

社会认知是指从环境互动的过程中推测他人意图、情感和思想等内部状态的心理加工过程。社会脑假说认为,包括人类在内的灵长类大脑内肯定存在着一个旨在认识和理解他人表情的神经机制,在社会交往中通过该中枢迅速处理与他人相互作用的各种信息。本文通过回顾社会脑的构成与基本功能,镜像神经元的发现及功能,以及社会脑、镜像神经元对社会认知影响的相关研究,提出了人类社会认知不同于其他物种的三个主要区别。     

从医学看巫术、宗教与科学的关系

医学是巫术、宗教、科学三者联系最多的门类,巫术在我国-始终盛行。近２０年有所抬头 ,其原因非常复杂。区别巫术与宗教、巫术与科学,是减少巫术危害最基本的方法。就此问题进行了深入阐述。     

句子重音对汉语同音异义词的解歧作用

通过针对包含两对汉语同音异义词(“qui(4)shi(4)”(“趣事”或“去世”和“sheng(1)xue(2)”(“声学”或“升学”))的10个发音人语料的声学特征分析和知觉实验,结果发现：消除这两对同音异义词歧义的不是词重音而是句子重音。这个研究结果说明：汉语中句子重音能够通过选择强调同音异义词的某个音节来消除它们的歧义。     

国外关于韵律特征和重音的一些研究

该文对韵律特征（包括其中的重音）这一研究领域近年的一些主要研究成果进行了一个小结。小结分两部分：（１）韵律特征及其作用;（２）关于重音的研究。文章对后者进行较详细的讨论,这个讨论分为重音的声学参数、重音的作用以及重音和其它韵律特征变量相互作用三个部分。     

三维物体图形的大小和颜色影响内隐和外显记忆的实验研究

本研究探索非言语信息的内隐记忆。用新异的不熟悉的三维物体图形作为实验材料,物体决定测验评价内隐记忆,是/否再认测验评价外显记忆,操纵学习(?)测验间物体图形的颜色(实验一)和大小(实验二),80名被试参加实验一,另80名参加实验二。结果发现:(1)存在着非言语信息的内隐记忆,且与外显记忆相分离;(2)新异的不熟悉三维物体的颜色和大小由外显记忆的情节系统所表征,而非属于结构表征系统,从而支持多重记忆系统假说。     

Influence of perceived emotion and gender on social motor coordination

Theorists have long postulated that facial properties such as emotion and sex are potent social stimuli that influence how individuals act. Yet extant scientific findings were mainly derived from investigations on the prompt motor response upon the presentation of affective stimuli, which were mostly delivered by means of pictures, videos, or text. A theoretical question remains unaddressed concerning how the perception of emotion and sex would modulate the dynamics of a continuous coordinated behaviour. Conceived in the framework of dynamical approach to interpersonal motor coordination, the present study aimed to address this question by adopting the coupled-oscillators paradigm. Twenty-one participants performed in-phase and anti-phase coordination with two avatars (male and female) displaying three emotional expressions (neutral, happy, and angry) at different frequencies (100% and 150% of the participant's preferred frequency) by executing horizontal rhythmic left-right oscillatory movements. Time to initiate movement (TIM), mean relative phase error (MnRP), and standard deviation of relative phase (SDRP) were calculated as indices of reaction time, deviation from the intended pattern of coordination, and coordination stability, respectively. Results showed that in anti-phase condition at 150% frequency, MnRP was lower with the angry and the female avatar. In addition, coordination was found to be more stable with the male avatar than the female one when both displaying neutral emotion. But the happy female avatar was found to elicit more stable coordination than the neutral female avatar. These results implied that individuals are more relaxed to coordinate with the female than the male, and the sensorimotor system becomes more flexible to coordinate with an angry person. It is also suggested social roles influence how people coordinate, and individuals attend more to interact with a happy female. In sum, the present study evidenced that social perception is embodied in the interactive behaviour during social interaction.     

普通话韵律词重音知觉

实验一研究了韵律词重音的多个声学相关物,及其对韵律词重音知觉贡献的大小,结果表明,按照贡献大小的次序,影响普通话韵律词重音感知的声学参数是：时长、音高、频谱倾斜和平均能量。实验二研究非声学参数因素对普通话韵律词重音知觉的影响,实验结果表明,听者关于普通话韵律词重音方面的语言学知识对韵律词重音的知觉有显著影响。     

稳定性冠心病介入治疗的理性思考

介入治疗是冠心病治疗的重要手段之一。但目前在稳定性冠心病的治疗中出现了过度使用的问题。因此我们必须理性地认识到,包括冠脉介入治疗（PCI）在内的血运重建措施只是重要的治疗手段之一,而绝非其全部。在稳定性冠心病治疗中,健康教育、改变生活方式、充分的药物治疗也是不可或缺的部分。     

质疑中医但不要否定中医

讨论了目前中西医争论的现状,分析了西医和中医的起源及发展过程,提出当现代医学向生物、心理、社会、医学模式转变时,中医可为这种转变提供思想和方法的借鉴,认为西医与中医是世界性医学与地方性医学的关系,根据医学发展的规律,地方性医学最终将能融入世界性医学之中,但在相当长时间内两者还会独立存在。
