为探讨主题关系在儿童归纳推理中的作用,采用经典的三角归纳范式,设计了主题关系和知觉相似冲突、主题关系和分类学关系冲突两种情形,来考察4~5岁儿童在内在属性和情境性属性任务中的归纳推理。结果显示:当主题关系和知觉相似冲突时,从4.5岁开始儿童主要基于主题关系对情境性属性进行归纳推理,而对于内在属性的推论,4~5岁儿童在基于主题关系和基于知觉相似上没有显著差异。当主题关系和分类学关系冲突时,从4.5岁开始儿童主要基于主题关系对情境性属性进行归纳推理,从5岁开始儿童主要基于分类学关系对内在属性进行归纳推理。两个实验结果均发现5岁和5.5岁儿童能够依据不同的属性使用不同的关系推理,表现出归纳灵活性  相似文献

We studied asymmetric competition between two (three‐person) groups. Each group member received an initial endowment and had to decide whether or not to contribute it. The group with more contributions won the competition and each of its members received a reward. The members of the losing group received nothing. The asymmetry was created by randomly and publicly selecting one group beforehand to be the winning group in the case of a tie. A theoretical analysis of this asymmetric game generates two qualitatively different solutions, one in which members of the group that wins in the case of a tie are somewhat more likely to contribute than members of the group that loses, and another in which members of the group that loses in the case of a tie are much more likely to contribute than members of the group that wins. The experimental results are clearly in line with the first solution. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

采用经典的三角归纳范式(Gelman & Markman,1986)研究了3岁儿童的归纳推理及其影响因素。采用龙长权、路晓英、李红和范籍丹(2008)的研究中相同的实验材料和程序,测试了3岁儿童的归纳,结果表明3岁儿童基于知觉相似和基于概念类别之间的差异不显著(实验一)。增加了与靶刺激在知觉上不相似且不属于同一类别的分心刺激之后,3岁儿童能够忽略分心刺激,表明3岁儿童不是在随机猜测(实验二)。分类实验表明3岁儿童能够根据概念关系对实验材料中的项目进行分类,表明3岁儿童具有关于实验项目的概念知识(实验三)。提高概念比较刺激与靶刺激的知觉相似程度,降低知觉比较刺激和概念比较刺激与靶刺激在知觉相似上的冲突程度之后,3岁儿童基于知觉相似和基于概念类别选择之间的差异仍不显著,表明抑制控制不是导致儿童在实验一中表现出基于知觉相似和基于概念类别之间差异不显著的原因(实验四)。降低概念比较刺激与靶刺激之间的类别等级结构,使概念比较刺激与靶刺激属于相同的基本水平类别时,3岁儿童能够主要基于概念类别进行归纳(实验五)。增加经典三角测试的前提的数量,3岁儿童也能主要基于概念类别进行归纳(实验六)。这些研究表明,3岁儿童在一定条件下能够基于概念类别进行归纳,多个因素能够影响3岁儿童在三角测试中的表现。  相似文献

A simple and very general algorithm for oblique rotation is identified. While motivated by the rotation problem in factor analysis, it may be used to minimize almost any function of a not necessarily square matrix whose columns are restricted to have unit length. The algorithm has two steps. The first is to compute the gradient of the rotation criterion and the second is to project this onto a manifold of matrices with unit length columns. For this reason it is called a gradient projection algorithm. Because the projection step is very simple, implementation of the algorithm involves little more than computing the gradient of the rotation criterion which for many applications is very simple. It is proven that the algorithm is strictly monotone, that is as long as it is not already at a stationary point, each step will decrease the value of the criterion. Examples from a variety of areas are used to demonstrate the algorithm, including oblimin rotation, target rotation, simplimax rotation, and rotation to similarity and simplicity simultaneously. While it may be, the algorithm is not intended for use as a standard algorithm for well established problems, but rather as a tool for investigating new methods where its generality and simplicity may save an investigator substantial effort.The author would like to thank the review team for their insights and recommendations.  相似文献

Using Quality Management System (QMS) enables the organization to fulfil its purpose and mission to meet customers and regulatory requirements and improve its effectiveness and efficiency on a continuous basis, Quality Audit is very critical tool to ensure that the standards, policies and/or procedures are applied in the organization as planned in QMS, in real world applications, the results of the Quality Audit process depend on the auditors’ human judgments that characterized with doubts sometimes, estimating values another times, and using general impressions in his judgment, which motivate to introduce for the first time the Neutrosophic Quality Audit (NQA) model which can be extended to manage and audit in the future. NQA will be used to enhance the way of evaluating the quality audit results while many uncertainty aspects and indeterminacy do exist, the proposed model using Single Value Neutrosophic Numbers (SVNN) which is an instance of neutrosophic set, to overcome the weakness of using a crisp value to present the result of the audit findings, in addition, using Simplified Neutrosophic Weighted Geometric Average Operator (SNWGAO), and cosine similarity degree, an illustrative example is provided to validate the proposed model.  相似文献

Value transmission from one generation to the next is a key issue in every society, but it is not clear which parents are the most successful in transmitting their values to their children. We propose parents’ prosocial educational goals as key predictors of parent–child value similarity. Accordingly, we hypothesized that the more parents wanted their children to endorse values of self‐transcendence (helping, supporting, and caring for others) and the less parents wanted their children to endorse the opposing values of self‐enhancement (striving for power and achievement), the higher would be parent–child overall value similarity. Findings from two studies of families – Study 1: 261 Swiss families, children aged 7–9 years; Study 2: 157 German families, children aged 6–11 years – confirmed this hypothesis. The effect was even stronger after controlling for values that prevail in the Swiss and German society, respectively. We integrate evidence from this study of values in families with young children with existing findings from studies with adolescent and adult children, and we discuss potential pathways from parents’ educational goals to parent–child value similarity.  相似文献

探讨个体与同伴的调节聚焦对目标追求的影响及感知相似性在其中的作用。回归分析显示,个体促进聚焦×同伴促进聚焦交互项显著预测同伴作用评价、求助意愿及动机水平,简单斜率分析表明,同伴为高促进聚焦时个体促进聚焦的积极效应更明显。中介分析表明,感知相似性是个体促进聚焦×同伴促进聚焦交互项与同伴作用评价、求助意愿之间关系的中介变量。总的来说,同伴调节聚焦能调节个体调节聚焦与目标追求的关系,且这一作用部分受到感知相似性的中介。  相似文献

3~5岁儿童表面与结构相似性类比推理的实验研究   总被引:2,自引:0,他引:2

采用经典类比推理问题对3~5岁儿童表面相似性与结构相似性类比推理能力进行了实验研究。结果发现:(1)表面相似性与结构相似性对儿童解决类比问题的影响不同。一般来说,前者更有利于3~5岁儿童类比问题的解决;(2)儿童解决表面相似性与结构相似性类比问题的能力随年龄增长而发展,但发展趋势不同。在表面相似性问题方面,4岁以前发展较慢,而4岁以后的发展较快;在结构相似性问题方面,4岁以前发展较快,而4岁以后的发展较慢。4岁是儿童解决类比推理问题能力的转折点;(3)在本实验条件下,工作记忆负荷对儿童解决表面相似性类比问题与结构相似性类比问题的影响不显著;(4)类比映射关系提示能促进儿童解决两类类比问题,但对不同年龄儿童的作用是非线性的。  相似文献

Semantic similarity measurement aims to determine the likeness between two text expressions that use different lexicographies for representing the same real object or idea. There are a lot of semantic similarity measures for addressing this problem. However, the best results have been achieved when aggregating a number of simple similarity measures. This means that after the various similarity values have been calculated, the overall similarity for a pair of text expressions is computed using an aggregation function of these individual semantic similarity values. This aggregation is often computed by means of statistical functions. In this work, we present CoTO (Consensus or Trade-Off) a solution based on fuzzy logic that is able to outperform these traditional approaches.  相似文献
