Sound to meaning correspondences facilitate word learning

A fundamental assumption regarding spoken language is that the relationship between sound and meaning is essentially arbitrary. The present investigation questioned this arbitrariness assumption by examining the influence of potential non-arbitrary mappings between sound and meaning on word learning in adults. Native English-speaking monolinguals learned meanings for Japanese words in a vocabulary-learning task. Spoken Japanese words were paired with English meanings that: (1) matched the actual meaning of the Japanese word (e.g., “hayai” paired with fast); (2) were antonyms for the actual meaning (e.g., “hayai” paired with slow); or (3) were randomly selected from the set of antonyms (e.g., “hayai” paired with blunt). The results showed that participants learned the actual English equivalents and antonyms for Japanese words more accurately and responded faster than when learning randomly paired meanings. These findings suggest that natural languages contain non-arbitrary links between sound structure and meaning and further, that learners are sensitive to these non-arbitrary relationships within spoken language.     

Probability matching in choice under uncertainty: Intuition versus deliberation

Gaissmaier and Schooler (2008) [Gaissmaier, W., & Schooler, L. J. (2008). The smart potential behind probability matching. Cognition, 109, 416-422] argue that probability matching, which has traditionally been viewed as a decision making error, may instead reflect an adaptive response to environments in which outcomes potentially follow predictable patterns. In choices involving monetary stakes, we find that probability matching persists even when it is not possible to identify or exploit outcome patterns and that many “probability matchers” rate an alternative strategy (maximizing) as superior when it is described to them. Probability matching appears to reflect a mistaken intuition that can be, but often is not, overridden by deliberate consideration of alternative choice strategies.     

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。     

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.
