Number words in young children's conceptual and procedural knowledge of addition, subtraction and inversion

Three studies addressed children's arithmetic. First, 50 3- to 5-year-olds judged physical demonstrations of addition, subtraction and inversion, with and without number words. Second, 20 3- to 4-year-olds made equivalence judgments of additions and subtractions. Third, 60 4- to 6-year-olds solved addition, subtraction and inversion problems that varied according to the inclusion of concrete referents and number words. The results indicate that number words play a different role in conceptual and procedural development. Children have strong addition and subtraction concepts before they can translate the physical effects of these operations into number words. However, using number words does not detract from their calculation procedures. Moreover, consistent with iterative relations between conceptual and procedural development, the results suggest that inversion acquisition depends on children's calculation procedures and that inversion understanding influences these procedures.     

今齐方言中的古语词论析

今齐方言中有大量的古语词,这些古语词是通过漫长的历史时期层层积淀的结果。从历时角度而言,今齐方言中的古语词基本上可以分为上古、近古、中古三个历史层次;从共时的角度而言,它们存在于共时平面的形、音、义,又与历史上的古语表现出不同的面貌。     

职业弹性对工作绩效和职业满意度影响的实证研究

摘要：职业弹性是指个体灵活应对变化的职业环境甚至是逆境的职业能力。在控制无关变量及同一方法偏差的基础上,本文考察了职业弹性的不同维度对其后效变量的影响。通过对某信息集团下属的59家电子相关企业中的324位管理人员的问卷调查,结果表明职业弹性会影响个体的工作绩效和职业满意度,管理者的职业弹性越高,其工作绩效越高、职业满意度也越高。     

From grammatical number to exact numbers: early meanings of 'one', 'two', and 'three' in English, Russian, and Japanese

This study examined whether singular/plural marking in a language helps children learn the meanings of the words 'one,' 'two,' and 'three.' First, CHILDES data in English, Russian (which marks singular/plural), and Japanese (which does not) were compared for frequency, variability, and contexts of number-word use. Then young children in the USA, Russia, and Japan were tested on Counting and Give-N tasks. More English and Russian learners knew the meaning of each number word than Japanese learners, regardless of whether singular/plural cues appeared in the task itself (e.g., "Give two apples" vs. "Give two"). These results suggest that the learning of "one," "two" and "three" is supported by the conceptual framework of grammatical number, rather than that of integers.     

汉字词和图片命名与分类的比较

采用命名与分类任务考察了汉字词和图片命名与分类的特点,揭示义符在汉字词和图片命名与分类中的作用。结果表明,汉字词和图片的命名与分类与拼音文字的词和图片的命名和分类既有共性,又有差异。汉字词和图片的命名与分类具有不对称性：汉字词的命名快于汉字词的分类,图片的分类快于图片的命名。义符对于汉字词和图片的命名与分类的影响具有不对称性：对汉字词的加工有重要影响,对图片的加工无影响;对汉字词的分类有重要影响,对汉字词的命名无影响。被试对有标示类别的义符的词的分类显著快于对无标示类别的义符的词的分类,甚至快于对图片的分类。所以如此,与汉字词的结构特点有关。汉字形声字多用义符来标记事物的类别,提供了重要的类别信息。根据上述结果,作者构建了汉字词和图片认知加工的综合模型     

The logical syntax of number words: Theory, acquisition and processing

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. Cognition93, 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar implicatures: Experiments at the semantics-pragmatics interface. Cognition, 86, 253-282; Hurewitz, F., Papafragou, A., Gleitman, L., Gelman, R. (2006). Asymmetries in the acquisition of numbers and quantifiers. Language Learning and Development, 2, 76-97; Huang, Y. T., Snedeker, J., Spelke, L. (submitted for publication). What exactly do numbers mean?]. Specifically, these studies have shown that data from experimental investigations of child language can be used to illuminate core theoretical issues in the semantic and pragmatic analysis of number terms. In this article, I extend this approach to the logico-syntactic properties of number words, focusing on the way numerals interact with each other (e.g. Three boys are holding two balloons) as well as with other quantified expressions (e.g. Three boys are holding each balloon). On the basis of their intuitions, linguists have claimed that such sentences give rise to at least four different interpretations, reflecting the complexity of the linguistic structure and syntactic operations involved. Using psycholinguistic experimentation with preschoolers (n = 32) and adult speakers of English (n = 32), I show that (a) for adults, the intuitions of linguists can be verified experimentally, (b) by the age of 5, children have knowledge of the core aspects of the logical syntax of number words, (c) in spite of this knowledge, children nevertheless differ from adults in systematic ways, (d) the differences observed between children and adults can be accounted for on the basis of an independently motivated, linguistically-based processing model [Geurts, B. (2003). Quantifying kids. Language Acquisition, 11(4), 197-218]. In doing so, this work ties together research on the acquisition of the number vocabulary with a growing body of work on the development of quantification and sentence processing abilities in young children [Geurts, 2003; Lidz, J., Musolino, J. (2002). Children’s command of quantification. Cognition, 84, 113-154; Musolino, J., Lidz, J. (2003). The scope of isomorphism: Turning adults into children. Language Acquisition, 11(4), 277-291; Trueswell, J., Sekerina, I., Hilland, N., Logrip, M. (1999). The kindergarten-path effect: Studying on-line sentence processing in young children. Cognition, 73, 89-134; Noveck, I. (2001). When children are more logical than adults: Experimental investigations of scalar implicature. Cognition, 78, 165-188; Noveck, I., Guelminger, R., Georgieff, N., & Labruyere, N. (2007). What autism can tell us about every . . . not sentences. Journal of Semantics,24(1), 73-90. On a more general level, this work confirms the importance of integrating formal and developmental perspectives [Musolino, 2004], this time by highlighting the explanatory power of linguistically-based models of language acquisition and by showing that the complex structure postulated by linguists has important implications for developmental accounts of the number vocabulary.     

汉语并列式合成词的词汇通达

汉语并列式合成词具有三种类型,这三种类型内部不同的词素组合在心理词典中则需要不同的词汇通达时间。实验结果表明,在对汉语并列式合成词的词汇通达过程中,第一成分并不总是起决定作用;同样,并列式合成词中的两个成分在词汇通达过程中并不总是同等重要。实验证明,语义透明度对并列式合成词的词汇通达起重要作用。实验还发现,在心理词典中对并列式合成词的词汇通达需要一个证实原则。     

11—14个月儿童的语言获得——成人的言语教授和儿童的模仿学习

对儿童言语记录个案的分析表明:儿童在11—14个月期间开始获得词。此时儿童所获得的词,主要是与儿童日常生活或动作相联系的名词和动词,其次是象声词。这些词语87.5％来源于成人的言语教授和儿童相应的模仿学习。 成人的言语教授和儿童相应的模仿学习总是由成人结合情景进行的,具有很高的选择性。儿童对成人言语的学习并不是简单地模仿,而是有一定的主动性和创造性,这在一定程度上规定着成人言语教授的作用。由此可见,儿童言语的获得是在人类特有的大脑以及言语器官发育的基础上,在与人们交际过程中,经过成人的言语教授,并经儿童有选择的模仿学习和概括而成的。     

The factor structure of the Maslach Burnout Inventory in two Swedish human service organizations

The Maslach Burnout Inventory, MBI, is a well established measure of burnout. Its validity outside the USA is, however, uncertain. The aim of the present study was therefore to apply the MBI on personnel in two Swedish human service organizations, comparing factor solutions and scoring norms to the original results. The population consisted of 5730 employees in the Social Insurance Organization (SIO) and the Individual and Family Care section (IFC) of the social welfare agencies. Principal components analysis, principal axes and alpha factor analyses were performed, all with varimax rotation. The suggested three factor solution showed to be remarkably stable irrespective of type of analysis. Score levels were somewhat lower on two subscales in the Swedish population. The conclusion is that the psychometric properties of the MBI seem to be very satisfactory and stable, at least in comparison between Sweden and USA. It is suggested that the dimensionality of MBI is rather invariant, but that the score levels covary with national, cultural, or professional contexts within the human services.     

字符的知觉表征及其启动

实验以英文单词,汉字和图片为材料,采用速示补笔测验测量了大脑左右半球的启动效应。结果是,如果学习与测验的字体和大小不变,则视觉启动右半球高于左半球。其他材料不产生这种效应。这表明,至少有一个分离的系统对构成启动的汉字的视觉表征进行编码,此系统在右半球表征形状特异形状特异信息更有效;对字符抽象特征的表征,两半球无显著差异,速示补笔测量的是前语义水平的知觉表征,是一种知觉（数据驱动）内隐记忆测验。
