人格理论的系统发展观初探

文章以遗传论、精神动力论、学习论、特质论、社会文化及认知一情感系统理论为基础。利用系统科学中的系统论观点,对人格理论进行系统发展观分析。该观点将人格看作一个复杂的“大”系统,它包括外部系统和内部系统两部分。外部系统即外环境系统,内部系统则分为个体心理系统和个体行为系统,其核心是个体心理系统,它由认识系统、情意系统、自我系统及需要系统构成。人格的形成是内外两个系统相互作用、循环运动的结果。     

School Mobility and Achievement: Longitudinal Findings From an Urban Cohort

This study investigated the effects of school mobility on reading and math achievement for 1,087 low-income Black children in the Chicago Longitudinal Study. Between kindergarten and seventh grade, 73% of the students changed schools at least once during elementary school and 21% changed schools three or more times. The prospective longitudinal design of the Chicago Longitudinal Study allowed for controlled analyses of both the predictors and the consequences of school mobility. The significant predictors of the number of moves included prior achievement, the number of years of preschool participation in an education intervention program, and parent education. Although the students who changed schools frequently between kindergarten and seventh grade performed approximately one year behind their nonmobile peers on reading and mathematics achievement tests taken at the end of seventh grade, only one half of this difference appears attributable to frequent mobility. The remaining portion is due to the fact that the mobile students were lower achieving even before they started to change schools. The negative consequences of past school mobility are lower for students who moved into better quality schools such as magnets or academic academies. Findings indicate that it is frequent, rather than occasional, mobility that significantly increases the risk of underachievement.     

On Being One's Own Person

The aim of the paper is to provide a philosophical account of our sense that some people are more their own person than others. I begin by exposing the weaknesses in three possible accounts, which I label the "interventionist", the "existentialist" and the "ideal" accounts. I then go on to argue that the distinguishing feature of those who are their own person is that their natural inclinations are accurately expressed in their behaviour.     

Imagery Value,Subjective and Objective Frequency,Date of Entry into the Language,and Degree of Polysemy in a Sample of 998 French Words

A random sample of 998 lexical words was drawn from a dictionary of the French language. Two groups of subjects rated the words for imagery value (IV) and subjective frequency (SF). Despite substantial individual differences in the ratings, the subjective measures were highly reliable (α = 0.98 for both IV and SF). The relation between the standard deviation and the mean of the ratings can be described by a quadratic function (R = 0.93 for IV and R = 0.75 for SF). The independence of IV and frequency was confirmed. IV was found to be partially dependent on grammatical category (η = 0.50) and slightly dependent on polysemy. Date of entry into the language (DE) was correlated with objective and subjective frequency. The correlation between DE and IV was weak. The words and their characteristics are presented in the Appendix.     

Optimal scaling of paired comparison and rank order data: An alternative to guttman's formulation

A formulation, which is different from Guttman's is presented. The two formulations are both called the optimal scaling approach, and are proven to provide identical scale values. The proposed formulation has at least two advantages over Guttman's. Namely, (i) the former serves to clarify close relations of the optimal scaling approach to those of Slater and the vector model of preferential choice, and (ii) in addition to the stimulus scale values, it provides scores for the subjects, which indicate the degrees of response consistency (transitivity), relative to the optimum solution. The method is assumption-free and capable of multidimensional analysis.This study was partly supported by the National Research Council Grant (No. A4581) to S. Nishisato. The author is indebted to Dr. Bert F. Green, Jr., Mr. Tomoichi Ishizuka, and anonymous reviewers for their valuable comments on an earlier draft.     

Effects of conditionality on INDSCAL and ALSCAL weights

The role of conditionality in the INDSCAL and ALSCAL procedures is explained. The effects of conditionality on subject weights produced by these procedures is illustrated via a single set of simulated data. Results emphasize the need for caution in interpreting subject weights provided by these techniques.     

Need for Cognition and Choice Framing Effects

Two experiments tested the hypothesis that framing biases in decision making would affect more strongly individuals with relatively low levels of need for cognition (NC). Participants were classified as high or low NC based on responses to a standard scale and subsequently were exposed to one of two framings of a choice problem. Different choice problems were used in each experiment, modeled after those developed by Kahneman and Tversky. Experiment 1 employed a monetary task and Experiment 2 a medical decision-making task. Consistent with expectations, framing effects on choice were observed in both experiments, but only for low NC participants. High NC participants were unaffected by problem framing, showing that they were less susceptible to attempts to alter their frame of reference.     

12岁儿童充分条件假言推理能力发展的个体差异研究

以三类不同题目（与生活经验密切联系、与生活经验相悖、与生活经验“脱离”）,探查了12岁普通儿童与数学成绩优异儿童充分条件假言推理能力发展的个体差异。通过对测查成绩的聚类分析,可将被试划分为四种不同的类型,从而显示出同一年龄儿童不同的推理能力发展水平：普通组儿童有关推理能力已有初步发展,但推理过程仍经常受其具体内容的束缚;数学成绩优异组儿童假设思维和演绎推理能力协调发展,“形式”从“内容”的束缚中解放出来,推理思维活动能较好地符合有关逻辑规则。这两组儿童假言推理能力的差异可能跟智能水平有关。
