笛卡尔的“心身二元论”开启了近代以来的心智哲学,他提出的心身问题的两个方面,即心身区别和心身因果相互作用,似乎构成了迄今为止笛卡尔哲学的辩护者和反对者的共同领域。笛卡尔给他的后继者们留下两种可能性:或者是消解二元对立;或者是修订相互作用论,其后世的心智哲学基本上是沿着这两条道路前进的。而当代心智哲学对意识的分析也具体体现了现代哲学对于传统的作为认识主体的“心灵实体”的解构。一 意识的难解之谜关于意识的研究所面对的是两种不同的对象:一种是从主观的角度用内省方法得到的自己头脑中的“内部现象”,我们据此承认意…  相似文献

General solutions of the analysis of variance in the case of unequal numbers of observations in the subclasses are presented. If we havek criteria for the classification, there will bek! solutions in making a complete analysis and 2k–1 answers, bearing different meanings, for the sum of squares between subclasses of each criterion. The sum of squares for the interaction of any order, however, will be identical in different solutions of same problem.  相似文献

This is the report of the application of the principles of factorial design to an investigation of individual educational development. The specific type of factorial design formulated was a 2 × 3 × 3 × 3 arrangement, that is, the effect of sex, grade location, scholastic standing, and individual order, singly and in all possible combinations was studied in relation to educational development as measured by theIowa Tests of Educational Development. An application of the covariance method was introduced which resulted in increased precision of this type of experimental design by significantly reducing experimental error. The two concomitant measures used to increase the sensitiveness of the experiment were initial status of individual development and mental age. Without these statistical controls all main effects and two first-order interactions would have been accepted as significant. With their use only sex (doubtful), scholastic standing, and individual order demonstrated significant effects. The chief beauty of the analysis of variance and covariance as an integral part of a self-contained experiment is demonstrated in the complete single analysis of the data. The statistical utilization of the experimental results has also been developed for purposes of estimation and prediction. The mathematical statistician is being continuously required to develop and analyze experimental designs of increasing complexity since the introduction of the analysis of variance and covariance. The mathematical formulation and solution of the problem of this investigation is carried out. The methods illustrated and explained in this study, and modifications and extensions of them are capable of very wide application. The general principles can be used to various degrees and in a number of ways.For the research grant to finance this study, grateful acknowledgment is given to the Graduate School, the University of Minnesota.  相似文献

自杀导致人类死亡的人数与日俱增,然而自杀的心理机制却并不清楚。最近研究发现,厌恶情绪是导致自杀的主要情绪因素,个体因为自身厌恶而走向自杀。厌恶情绪是一种对自己和他人排泄物等反感的基本情绪,促进个体远离毒性和疾病,从而产生“免疫行为”。许多心理问题来自于对周围人或事物的厌恶,有自杀行为的个体对自身极其厌恶,说明他们的厌恶情绪出现了问题。如同躯体免疫攻击自身一样,自身厌恶是自杀意念的关键因素,早年创伤是其根源,生活压力和精神疾病也参与厌恶诱发自杀意念。厌恶诱发自杀意念的神经基础与HPA轴和五羟色胺系统有关。未来研究可利用神经影像和电生理等神经科学技术,检验自杀行为的神经机制,探讨厌恶情绪影响自杀行为的心理和神经机制。  相似文献

The mathematical connection between canonical correlation analysis (CCA) and covariance structure analysis was first discussed through the Multiple Indicators and Multiple Causes (MIMIC) approach. However, the MIMIC approach has several technical and practical challenges. To address these challenges, a comprehensive COSAN modeling approach is proposed. Specifically, we define four COSAN-CCA models to correspond with four possible combinations of the data to be analyzed and the unique parameters to be estimated. In terms of the data, one can analyze either the unstandardized or standardized variables. In terms of the unique parameters, one can estimate either the weights or loadings. Besides the unique parameters of each COSAN-CCA model, all four COSAN-CCA models also estimate the canonical correlations as their common parameters. Taken together, the four COSAN-CCA models provide the correct point estimates and standard error estimates for all commonly used CCA parameters. Two numeric examples are used to compare the standard error estimates obtained from the MIMIC approach and the COSAN modeling approach. Moreover, the standard error estimates from the COSAN modeling approach are validated by a simulation study and the asymptotic theory. Finally, software implementation and future extensions are discussed.  相似文献

近年来团队权力分布差异与团队冲突间关系受到了学界较大关注, 但相关研究结果仍存在分歧。通过对70个工作团队的调查, 探讨了团队权力分布差异对团队冲突(任务冲突、关系冲突)作用的边界条件。结果发现, 程序公平调节了两者间关系:当程序公平较高时, 团队权力分布差异与任务冲突、关系冲突负相关; 当程序公平较低时, 团队权力分布差异与任务冲突、关系冲突正相关。此外, 被中介的调节模型分析显示, 团队合法性感知中介了程序公平的上述调节作用。  相似文献

Carbonization is one of the main methods for comprehensive utilization of bituminous coal. Bituminous coal and its solid products from carbonization, namely char and coke, have complex pore structures, which can be characterized by fractals. We performed a study on the fractal structure of the solid products prepared from the bituminous coal of Shuiyu mine in Shanxi Province, China, at different carbonization temperatures (25°C~1000°C) by synchrotron radiation small-angle X-ray scattering (SAXS). The results show that the bituminous coal has a surface fractal structure during the whole carbonization process. The variation of fractal dimension with carbonization temperature illustrates the different stages of the carbonization process.  相似文献

The purpose of this study was to explore Chinese Christians’ sense of self-worth, well-being, locus of control and the correlations between these variables. One hundred and two Chinese Christians with a range of 18–40 years old were surveyed by the Scale of Self-worth, Chinese version of General Well-Being Scale and internal–external Locus of Control Scale. A control group of 134 Chinese non-Christians participated in the same survey. Christians scored lower on locus of control and higher on self-worth than the non-Christians. No significant general well-being difference was between the Christian and non-Christian samples. The correlations were significant between locus of control and self-worth/general well-being (negative) and between self-worth and general well-being (positive). Results suggest that Christians experience better self-worth and tend to be internals on locus of control.  相似文献

权力和地位对自利行为的影响不同。权力能够降低认知性观点采择水平,进而使个体更加关注自身利益;地位能够提升认知性观点采择水平,进而使个体推测他人思想与感受,考虑他人利益。然而,权力和地位通过认知性观点采择对自利行为的影响可能受到情境性质的调节。今后的研究应该对这些关系和解释进行验证,探索共情性关心的中介作用,以及权力和地位影响认知性观点采择的调节变量;探究权力和地位拥有者对群体内、外他人的自利行为差异;探讨权力和地位的交互作用对自利行为的影响。  相似文献
