国外儿童认知发展与学习的最新研究述评

认知发展变化是儿童发展研究的中心课题,而儿童学习是研究儿童认知发展变化的一个重要方面。20世纪90年代以来,随着儿童学习重新研究,儿童认知发展研究取得显著进展。本文在最新儿童认知发展和学习研究的基础上,概述儿童早期认知能力的新发现以及儿童学习的有关研究和结论,并提出了新的研究框架。     

经济伦理学研究的双重向度

经济伦理学研究的向度问题缘起于八十年代的“内引”说与“外灌”说之争,突现于九十年代的道德功能大讨论。经济伦理学研究应当坚持两大向度:一个是目的向度,从人的生活出发,确定经济发展的根本目的,一个工具向度,从经济的内在要求出发,提供经济发展的道德手段。只有将这两大向度结合起来,才能真正确立经济伦理学的社会地位。     

On philosophical subjects and methods

With the consideration of some issues in contemporary philosophy, this thesis attempts to analyze being, thinking and language as philosophical subjects, and clear up the multiple meanings for each of them. It will also inquire the traditional methods in both Chinese and Western philosophy, and those in contemporary thinking. Finally, it puts forward a theory of “the critique without principles”. The thesis aims to explore a new way to solve the problems of contemporary philosophy by changing its subjects and methods. __________ Translated from Zhexue Yanjiu 哲学研究 (Philosophical Studies), 2005 (3) by Cheng Xuemeng     

Inferential theory for partially disattenuated correlation coefficients

Four measurement designs are presented for use with correlation coefficients corrected, in one variable, for attenuation due to unreliability—coefficients that we term partially disattenuated correlation coefficients. Asymptotic expressions are derived for the variances and covariances of the estimates accompanying each design. Empirical simulation results that bear on the preceding mathematical developments are then presented. In addition to providing insights into the distributions of the estimates, the empirical results demonstrate satisfactory Type I error control for typical inferential applications. Power is shown to be equal to or greater than that of corresponding product-moment correlations in three of the four designs. Implications for practice are discussed.Support for the research reported in this article was provided by the Natural Sciences and Engineering Research Council of Canada.

Statements of Method and Teaching: The Case of Socrates

In this paper, I ponder the question of whether Socrates follows a method of investigation — the method of hypothesis — which he advocates in Plato's Phaedo. The evidence in the dialogue suggests that he does not follow the method, which raises additional questions: If he fails to do so, why does he articulate the method? Does his statement of method affect his actions or is it mainly forgotten? Although Socrates is a fictional character, his actions in the Phaedo suggests questions about the function of espoused methods in actual situations.     

An improvement of the Harman-Fukuda-method for the minres solution in factor analysis

The method proposed by Harman and Fukuda to treat the so-called Heywood case in the minres method in factor analysis i.e., the case where the resulting communalities are greater than one, involves the frequent solution of eigenvalue problems. A simple method to treat this problem requiring less computing time and enjoying higher numerical stability is described in this paper.     

Generalized bilinear models

Generalized bilinear models are presented for the statistical analysis of two-way arrays. These models combine bilinear models and generalized linear modeling, and yield a family of models that includes many existing models, as well as suggest other potentially useful ones. This approach both unifies and extends models for two-way arrays, including the ability to treat response and explanatory variables differently in the models, and the incorporation of external information about the variables directly into the analysis. A unifying framework for the generalized bilinear models is provided by considering four particular cases which have been proposed and used in the existing statistical literature. A three-step procedure is proposed to analyze data sets by generalized bilinear models. Two data sets of different nature are analyzed.     

A one-way random effects model for trimmed means

The random effects ANOVA model plays an important role in many psychological studies, but the usual model suffers from at least two serious problems. The first is that even under normality, violating the assumption of equal variances can have serious consequences in terms of Type I errors or significance levels, and it can affect power as well. The second and perhaps more serious concern is that even slight departures from normality can result in a substantial loss of power when testing hypotheses. Jeyaratnam and Othman (1985) proposed a method for handling unequal variances, under the assumption of normality, but no results were given on how their procedure performs when distributions are nonnormal. A secondary goal in this paper is to address this issue via simulations. As will be seen, problems arise with both Type I errors and power. Another secondary goal is to provide new simulation results on the Rust-Fligner modification of the Kruskal-Wallis test. The primary goal is to propose a generalization of the usual random effects model based on trimmed means. The resulting test of no differences among J randomly sampled groups has certain advantages in terms of Type I errors, and it can yield substantial gains in power when distributions have heavy tails and outliers. This last feature is very important in applied work because recent investigations indicate that heavy-tailed distributions are common. Included is a suggestion for a heteroscedastic Winsorized analog of the usual intraclass correlation coefficient.
