Wittgenstein and contemporary theories of word learning

Wittgenstein's positions on word learning, rules of use, and the impossibility of a private language, as expounded in his Philosophical Investigations, are examined in relation to issues of early child word learning. Current theoretical positions in the cognitivist mode are contrasted with the social cultural pragmatic approach, and each is compared to the principles that Wittgenstein advanced. Bloom's [(2000). How children learn the meanings of words. Cambridge, MA: MIT Press] version of the cognitivist theory rejects most of the principles that Wittgenstein advanced, relying on innate cognitive endowments to explain children's success in word learning, using the word-referent mapping paradigm. Nelson's “use without meaning” and Tomasello's [(2003). Constructing a language: A usage-based theory of language acquisition. Cambridge, MA: Harvard University Press] social-pragmatic model of learning from use are presented as representative of Wittgensteinian principles that meaning exists in and is inferred from the uses of words within communal activities (“language games” in “forms of life”).     

目标或背景:联合搜索知觉学习的内容

采用颜色-形状联合搜索任务探讨短期特征联结知觉学习的效果和机制。训练被试在由不同颜色和形状组合的字母干扰子中搜索具有特定颜色和形状的目标字母,训练时间约为40分钟。通过训练,被试搜索特定的颜色-形状联结的目标字母的能力有所提升,并且学习效应能够迁移至背景改变目标不变的条件中,但是不能迁移至背景不变目标改变的条件中。这一结果提示,被试在进行短期联合搜索知觉学习时,学习到的是目标,而并非背景或目标与背景的联系。     

乳腺癌诊治过程中的多学科协作

乳腺癌是全身疾病,其治疗和诊断都需要多个学科的积极参与协作才能完成。本文就自身体会认为乳腺专科医生掌握诸如肿瘤外科技术与肿瘤内科治疗措施,熟悉乳腺癌放疗与美容整形的相关技术,并能掌握诸如乳腺B超等检查手段等多个学科知识,同时和病理等相关科室紧密协作,是处理好乳腺癌诊治过程中的多学科协作问题的一种有效方法。     

学习不良儿童社会性发展特点的研究

对211名10—15岁学习不良儿童社会性发展特点的研究表明,学习不良儿童在本研究确定的社会交往、自我概念和行为问题诸维度上具有独特的年龄和性别特点。学习不良女孩的社会性发展水平略高于学习不良男孩;随年龄递增．学习不良儿童的社会性发展水平不断得到提高,但其在不同年龄阶段的特点则有所不同。同时．学习不良儿童社会性发展诸方面存在着交互作用。     

Lifelong Education: From Conflict to Consensus?

The concept of lifelong education received wide criticism and rejection in many educational circles in the 1970s. Recent developments in educational research and the increasing influence of postmodernist thought, the paper argues, are major factors in the return to favour of lifelong education. While a postmodern society is one characterised more by conflict than by consensus, the paper suggests that consensus on the importance of lifelong education might be one precondition for such a society.     

Using Experiential Learning Theory to Train Career Practitioners

Effective instructional strategies are needed for career practitioner training. Experiential learning theory (ELT; A. Y. Kolb & Kolb, 2009) provides an instructional foundation from which awareness of the various components of career development can be enhanced. Support for ELT as an effective method of instruction exists in various fields (Hoover, Giambatista, Sorenson, & Bommer, 2010; Ti et al., 2009). ELT integrates 6 shared propositions derived from John Dewey, Jean Piaget, William James, Carl Jung, and Carl Rogers (A. Y. Kolb & Kolb, 2009). This article outlines components of ELT and their application in training career service practitioners.     

组织学习整合理论模型

如何提高组织学习能力、如何创建学习型组织、学习型社会,这已经成为我国企业和社会发展需要迫切解决的问题。文章从定义的根本假设、组织学习层次、组织学习过程、内部推动因素四个方面对文献进行了综述,在此基础上提出了组织学习的界定以及整合的组织学习模型,它包括：个体、团队、组织层、组织间四个学习层次,获得和产生、解释、整合、制度化四个心理和社会互动过程,反馈学习（feedback）和前馈学习(feed forward)两个信息或知识流动过程。最后提出了今后研究的方向。
