音乐的速度与调式对大学生情绪影响的实证研究

以92名大学本科生为实验对象,用剪辑的8首乐曲片断为实验材料,考察其调式和速度对大学生情绪的影响。结果表明:乐曲片断的速度对大学生的情绪影响非常显著,但调式的主效应不显著;慢速的乐曲易于诱发大学生忧伤、悲哀、痛苦、烦躁和愤恨等负性情绪;快速的乐曲大多数导致大学生愉悦与兴奋等正性情绪。乐曲的速度与调式对大学生情绪影响的差异十分显著。速度在调式上两水平的差异显著,尤其是在大调上差异非常显著。但调式只有在慢速水平上差异十分显著,而在快速水平上差异不显著。     

不同心理一致感个体压力情境下的情绪特点研究

以46名大学生为被试,利用“九洞仪”创设实验室压力情境,考察不同心理一致感个体压力情境下的情绪反应及恢复特点。结果表明：（1）压力情境下,高、低心理一致感个体的情绪反应存在显著性差异。高心理一致感个体出现较多的积极情绪,低心理一致感个体则以消极情绪体验为主。（2）低心理一致感压力情境诱发出的消极情绪显著多于积极情绪,消极情绪的诱发量较大。（3）压力任务后,高心理一致感个体在情绪恢复量上显著多于低心理一致感个体,心理健康的自我康复力较大。（4）压力任务前后,低心理一致感个体的消极情绪诱发量显著高于恢复量,在消极情绪变化上表现出“诱发多,恢复少”的特点。     

风险敏感理论:需要驱动风险决策

风险敏感理论由研究动物觅食行为发展而来,提出有机体在有需要的状况下会出现从风险规避到风险寻求的行为,是风险决策领域内的一种生物学理论。目前风险敏感理论所做出的预测在动物和人类身上都获得了大量实证研究的支持,表明该理论可以解释很多领域中的风险决策。因此有必要对这一理论做一个系统的论述,包括对其理论来源和数学模型的发展演变进行梳理;从参照点等不同的角度分析该理论与其他决策理论的区别;并且,风险敏感理论也为经济不平等和权力等外部因素下的风险转移提供了解释,对已有研究做出了独特的贡献。     

楚竹书《孔子诗论》“类序”辨析

通过对楚竹书《孔子诗论》的分析,结合对《诗经》文本形成过程的探讨,得出《诗经》之部类及其类序为《风》、《小雅》、《大雅》、《颂》的结论,同时厘清孔子、《孔子诗论》和《毛诗》在文本方面的关系。《诗经》的结集经历了一个过程,其分类由来已久;未曾更改。《诗》“类序”的形成也具有一定的历史性,是在《诗》文本编辑过程中自然形成的。孔子在整理《诗经》的过程中并不存在一个前提性的“编序”原则,所谓孔子“删诗”,只是对诗篇做些必要的一般性古籍整理而已。至于出土文献《孔子诗论》中偶尔出现的颠倒《诗》“类序”的论述亦属正常,并不能说明孔子曾编有与传统《诗》“类序”相反的文本,也不能否定《毛诗》文本具有一定的历史延续性,更不能由此说明《孔子诗论》中出现“类序颠倒”具有更为不可测知的寓意。     

Multi-response permutation procedure as an alternative to the analysis of variance: An SPSS implementation

A permutation test typically requires fewer assumptions than does a comparable parametric counterpart. The multi-response permutation procedure (MRPP) is a class of multivariate permutation tests of group difference useful for the analysis of experimental data. However, psychologists seldom make use of the MRPP in data analysis, in part because the MRPP is not implemented in popular statistical packages that psychologists use. A set of SPSS macros implementing the MRPP test is provided in this article. The use of the macros is illustrated by analyzing example data sets.     

Coh-metrix: analysis of text on cohesion and language.

Advances in computational linguistics and discourse processing have made it possible to automate many language- and text-processing mechanisms. We have developed a computer tool called Coh-Metrix, which analyzes texts on over 200 measures of cohesion, language, and readability. Its modules use lexicons, part-of-speech classifiers, syntactic parsers, templates, corpora, latent semantic analysis, and other components that are widely used in computational linguistics. After the user enters an English text, CohMetrix returns measures requested by the user. In addition, a facility allows the user to store the results of these analyses in data files (such as Text, Excel, and SPSS). Standard text readability formulas scale texts on difficulty by relying on word length and sentence length, whereas Coh-Metrix is sensitive to cohesion relations, world knowledge, and language and discourse characteristics.     

The Trajectory of Counseling in China: Past,Present, and Future Trends

This article surveys the past, present, and future trends of counseling in China. Historically, mental health problems were addressed within the family. Currently, psychotherapy from trained practitioners is available on a limited basis, at least in urban settings. The challenge of mental health in China is tremendous, and the efforts to meet that challenge are encouraging. The authors recommend that in the future, prevention and intervention services be offered that are ecosystemic, strengths‐based, and culturally appropriate.     

Role of Surface Roughness in Hysteresis during Adhesive Elastic Contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments that show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P-h curves are not unique.
