将一个图形(称为母图)的若干条线段删除后得到的图形叫做母图的子图。运用实验方法探讨了子图结构学习和子图变式学习对解决问题的迁移效果。结果表明:子图结构学习仅对解决“图形结构相同、逻辑结构相同”问题有明显迁移作用;子图变式学习对解决“图形结构相同、逻辑结构相同”没有明显迁移作用,对“图形结构相似、逻辑结构相同”、“图形结构相同、逻辑结构相似”以及“图形结构相似、逻辑结构相似”四类问题均有明显迁移作用。 相似文献

A recent report in Consciousness and Cognition provided evidence from a study of the rubber hand illusion (RHI) that supports the multisensory principle of inverse effectiveness (PoIE). I describe two methods of assessing the principle of inverse effectiveness (‘a priori’ and ‘post-hoc’), and discuss how the post-hoc method is affected by the statistical artefact of ‘regression towards the mean’. I identify several cases where this artefact may have affected particular conclusions about the PoIE, and relate these to the historical origins of ‘regression towards the mean’. Although the conclusions of the recent report may not have been grossly affected, some of the inferential statistics were almost certainly biased by the methods used. I conclude that, unless such artefacts are fully dealt with in the future, and unless the statistical methods for assessing the PoIE evolve, strong evidence in support of the PoIE will remain lacking. 相似文献

专家医生的知识结构及诊断推理方式 总被引:2,自引:0,他引:2
医学专长研究中“中间者效应”的发现,引发了研究者对专家医生知识结构的探讨。在“知识打包”的基础上,医生的临床知识以“疾病脚本”的方式组织起来。随着临床经验的增加,专家医生积累了丰富的疾病脚本。在临床诊断中,他们无需对病人所有的体征和症状进行仔细地和系统地分析,而是通过非分析性的推理方式——“模式识别”或“样例识别”便可自动激活与之匹配的疾病脚本,据此对病人做出迅速而准确的诊断。医学专长的本质就在于专家医生以“疾病脚本”的方式组织起来的知识结构。“适应性专长”代表了未来医学专长研究的新方向 相似文献

目前西方婚姻研究领域的主流—— 婚姻沟通研究表现出三大进展:从个体研究视角转向互动视角; 从单一维度划分沟通类型转向功能性的划分; 从人格影响因素的探索转向权力结构的探索。该领域未来的研究趋势应集中在关注积极互动、扩展研究范式、探索调节或中介机制、探讨夫妻权力的不同层面以及重新评价人格因素的影响等方面。 相似文献

中国人心理账户的内隐结构 总被引:10,自引:0,他引:10
“心理账户”是个人、家庭或企业集团在心理上对结果(尤其是经济结果)的记录、编码、分类和估价的心理过程,它揭示了人们进行资金(财富)决策时的内在认知编码。研究对全国9个省市1268名有效被试进行问卷调查,经过探索性因子分析、验证性因子分析以及二阶因子验证发现:中国人的心理账户系统有一个相对稳定的“3-4-2”分类结构。即收入账户有“工作相关的常规收入”、“非常规的额外收入”和“经营收入”三个账户;开支账户有“生活必需开支”、“家庭建设与个人发展开支”、“情感维系开支”和“享乐休闲开支”四个账户;存储账户有“安全型保障账户”和“风险型存储账户”两个账户。心理账户的分类研究对探究人们的经济决策行为有重要意义 相似文献

从耗散理论解读肿瘤的发病及治疗 总被引:1,自引:0,他引:1
肿瘤的综合治疗方案,即药物-社会-心理治疗已广泛地应用于临床,虽效果显著,但其机制尚缺乏确切的实验依据。笔者从耗散结构理论来解读这种综合疗法,认为药物、社会及心理治疗均是通过增加机体的负熵,使肿瘤患者的内环境处于有序平衡状态而改善其病情。从耗散理论出发可以将肿瘤的综合疗法更好地应用于临床。 相似文献

汉族儿童亲属词概念结构发展研究 总被引:1,自引:0,他引:1
采用自然分类和多维标度法,考察汉语儿童亲属词概念结构的发展。结果表明:(1)随着年龄增长,儿童亲属词概念结构的维度在变化。小学低年级学生出现性别和辈分维度,小学高年级学生出现辈分和成人/儿童维度,初中生出现亲属亲密程度维度,高二学生出现姻亲/非姻亲维度。(2)亲属词概念结构受儿童性别和生活经验影响。(3)个体概念结构发展和人类概念结构进化有类似之处。 相似文献

Children's engagement and competence in personal recollection: effects of parents' reminiscing goals 总被引:1,自引:0,他引:1
Parents' goal orientations in parent-child reminiscing were examined in this study, where 28 preschoolers (mean age = 46 months) experienced a standardized event. Dyads discussed the event that evening, with parents randomly assigned to either an "outcome-oriented" or a "process-oriented" condition. Outcome-oriented parents, who were told that children subsequently would be tested on event-related recall, were more controlling in these conversations compared with process-oriented parents, who were told that children's personal perspective would be assessed. Parents did not differ in their provision of structure. Children were interviewed 2 weeks later. Autonomy support in the parent-child conversation predicted children's engagement in the interview. Parental structure predicted children's recall of details and the coherence of their memories. Effects of parental reminiscing styles for children's memory and motivation to reminisce are discussed. 相似文献

Recent semantic approaches to scientific structuralism, aiming to make precise the concept of shared structure between models,
formally frame a model as a type of set-structure. This framework is then used to provide a semantic account of (a) the structure
of a scientific theory, (b) the applicability of a mathematical theory to a physical theory, and (c) the structural realist’s
appeal to the structural continuity between successive physical theories. In this paper, I challenge the idea that, to be
so used, the concept of a model and so the concept of shared structure between models must be formally framed within a single
unified framework, set-theoretic or other. I first investigate the Bourbaki-inspired assumption that structures are types
of set-structured systems and next consider the extent to which this problematic assumption underpins both Suppes’ and recent
semantic views of the structure of a scientific theory. I then use this investigation to show that, when it comes to using
the concept of shared structure, there is no need to agree with French that “without a formal framework for explicating this
concept of ‘structure-similarity’ it remains vague, just as Giere’s concept of similarity between models does ...” (French,
2000, Synthese, 125, pp. 103–120, p. 114). Neither concept is vague; either can be made precise by appealing to the concept of a morphism, but it is the context (and not any set-theoretic type) that determines the appropriate kind of morphism. I make use of French’s
(1999, From physics to philosophy (pp. 187–207). Cambridge: Cambridge University Press) own example from the development of quantum theory to show that, for
both Weyl and Wigner’s programmes, it was the context of considering the ‘relevant symmetries’ that determined that the appropriate
kind of morphism was the one that preserved the shared Lie-group structure of both the theoretical and phenomenological models.
