“均”与“寡”阶段性变动下中国居民公平感的变迁

利用中国综合社会调查和中国社会状况综合调查重复截面数据,通过年龄-时期-队列模型对居民公平感的时代变化进行分析。研究发现公平感在年龄上呈“J”型趋势;从时期效应看, 2008年公平感较高, 2010～2013年在低谷徘徊,2015年以后又开始回升;从队列视角看,建国前出生队列公平感偏低,建国后初期的队列相对较高,“50”后有所下滑,从“60”后开始公平感持续走低,到“80”后跌入低谷,但“90”后又开始升高。从1949年前后“寡且不均”到建国初期阶段的“寡且均”,再到改革开放40年快速经济增长下“不寡但不均”的社会变迁过程影响了居民的公平感。     

Generalization and response latency

The present experiments investigated generalization in a reactio? time situation where the generalization stimulus, a tone, preceded the reaction time signal, a light. The hypotheses under investigation were that the duration of the cue stimulus would determine the degree of generalization (Experiment I) and that the response latency independent of the stimulus duration would be related to the amount of generalization (Experiment II). A particular generalization test stimulus (a tone of 40, 45, 50, 60, 65, or 70 dB) was presented only once always following two bar-pressing responses to training stimulus (tone of 55 dB) under each of two conditions of stimulus duration in Experiment I and under each of two conditions of response latency in Experiment II. It was found that under the condition of short response latency generalization was broader.     

比较研究-影响中美儿童计算能力差异的认知因素

本研究要确定中美儿童基本计算技能的差异是否与他们使用的解题策略和基本加工过程的速度有关。为此,对中美两国的一年级儿童进行了书面计算能力测验,以及一组计算机呈现的加法作业。中国儿童在计算能力测验上表现出3:1的操作优势。中美儿童使用的解题策略种类一样,但是,中国儿童在策略综合运用的发展程度上超过美国儿童,检索策略的加工速度也超过美国儿童。显然,策略运用和加工速度的差异促成了中国儿童在计算能力测验上的优势.     

故事图式在故事理解中加工机制的初步实验研究

本实验利用两种不同回忆方式、两个双情节故事和小五、高一和大二共120名被试,初步研究了故事图式在故事理解中的加工机制。结果表明:(1)故事图式的加工机制主要表现为两级剪辑,特别是二级剪辑;(2)故事图式可以通过一定的方式来处理无关信息;(3)故事图式中与故事语法各类节点相对应的加工单元的力量是不同的,且因年龄而异。     

Computational and reasoning abilities in arithmetic: Cross-generational change in China and the United States

A Chinese advantage over Americans was found for economically relevant computational and reasoning abilities in arithmetic for groups of 6th- and 12th-grade students matched or equated on general intelligence. No cross-national difference for computational or reasoning abilities was found for samples of older (60- to 80-year-old) Chinese and American adults equated on general intelligence. The pattern of change in arithmetical competencies across cohorts suggests that the Chinese advantage in 6th and 12th grade is due to a cross-generational decline in competencies in the United States and a cross-generational improvement in China.     

Form symbolism, analogy, and metaphor

Simple forms, such as a square and a circle, can be symbolic; for example, a square can be deemed to behard and a circle to besoft. The relation between form symbolism and the comprehension of metaphors and analogies was studied in three experiments. Subjects were asked to rate matches between terms such assoft andhard andcircle andsquare as symbols (Experiment 1), metaphors (Experiment 2), and analogies (Experiment 3). The results show that a highly rated symbolic relation could be a poorly rated metaphorical relation. Ratings of analogies were similar to ratings of symbols. We argue that apt metaphors, analogies, and symbolic forms claim that the vehicle and the topic of the comparisons have common features, but that metaphoric representation entails more common features than does either symbolism or analogy, because metaphor requires that the vehicle be an especially apt example of a superordinate class. Thus, metaphor is a particularly strong claim about common features shared by the topic and the vehicle.

小学儿童合取概念的形成及其与元认知的关系

采用个别访谈与问卷相结合的方法．研究了小学四、五、六年级共48名儿童合取概念的形成及其元认知的发展。结果表明．小学儿童形成合取概念的能力发展既具有渐进性,又有不均衡性;其元认知知识水平和元认知监控能力的发展均呈现出稳中有变的趋势;各年级的元认知能力与形成合取概念的步数之间均存在非常显著的相关。     

Models and theories I: The semantic view revisited

The paper, as Part I of a two‐part series, argues for a hybrid formulation of the semantic view of scientific theories. For stage‐setting, it first reviews the elements of the model theory in mathematical logic (on whose foundation the semantic view rests), the syntactic and the semantic view, and the different notions of models used in the practice of science. The paper then argues for an integration of the notions into the semantic view, and thereby offers a hybrid semantic view, which at once secures the view's logical foundations and enhances its applicability. The dilemma of either losing touch with the practice of science or yielding up the benefits of the model theory is thus avoided.     

8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８－１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８－１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８－１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月的婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８－１１个月婴儿的学习速度随月龄增大而提高。
