Influences of vowel and tone variation on emergent word knowledge: a cross‐linguistic investigation

To learn words, infants must be sensitive to native phonological contrast. While lexical tone predominates as a source of phonemic contrast in human languages, there has been little investigation of the influences of lexical tone on word learning. The present study investigates infants’ sensitivity to tone mispronunciations in two groups of infants. For one group (Chinese learners), tone is phonemic in their native language, and for the second group (English learners), tone is non‐phonemic and constituted suprasegmental variation. In Experiment 1, English learners were trained on novel word–object pairings and tested on their recognition of correct pronunciations, tone and vowel mispronunciations of these words at 18 and 24 months. In Experiment 2a, bilingual English‐Chinese learners were tested on a similar task translated into Chinese at the same age intervals. Results demonstrate that non‐tonal learners treated tonal and vowel substitutions alike as mispronunciations at 18 months but only treated vowel substitutions as mispronunciations at 24 months. Tonal learners treated both tonal and vowel substitutions as mispronunciations at both ages. In Experiment 2b, bilingual non‐tone language learners were tested on the same set of tasks replicating a similar set of results as monolingual non‐tone language learners (Experiment 1). Findings point to an early predisposition to treat tone as a defining characteristic of words regardless of its lexical relevance at 18 months. Between 18 and 24 months, learners appear to ascribe lexical relevance to tone in a language‐specific manner. The current study identifies the influences of tone variation on memories for newly learned words and the time period during which lexical tone – a highly frequent constituent of human languages – actually becomes lexical for early learners. Findings are contextualized with prevailing models of the developing lexicon.     

邻近效应对多媒体学习中图文整合的影响:线索的作用

在多媒体学习中图文排列的邻近或远离会影响学习的效果。本研究操纵了多媒体呈现的图文排列位置,采用颜色作为线索引导注意,探讨了线索有无和图片-文字的空间位置对多媒体学习图文整合的影响。结果发现:图文邻近呈现时的保持测验和迁移测验成绩好于图文远离呈现,图文邻近呈现时学习者对关键兴趣区的进出次数更多,体现出以文字为导向的阅读模式。线索并没有单独影响学习成绩和注意分配;但结合图文位置后,发现有线索时图文邻近学习材料的注视次数、进出关键兴趣区的次数显著多于图文远离。研究认为:图文的邻近效应不仅提高学习者对知识的识记和理解,同时也影响了学习者的注意分配过程,图文邻近呈现有助于图片和文本信息的注意联结和知识整合;线索能使邻近效应得到凸显,更好地促进图文信息的注视加工,但没有改进学习的效果。     

Chinese University Students’ Perceptions of Plagiarism

This study examines Chinese undergraduates’ perceptions of plagiarism in English academic writing in relation to their disciplinary background (i.e., hard vs. soft disciplines), academic enculturation (i.e., length of study in university), and gender. Drawing on data collected from 270 students at two universities in China, it finds clear discipline-based differences in participants’ knowledge of plagiarism and perceptions about its causes; an enculturational effect on perceived acceptability of and condemnatory attitudes toward plagiarism, with senior students being less harsh than their junior counterparts; and complex interactions among disciplinary background, length of study, and gender. Furthermore, it reveals conceptions of (il)legitimate intertextuality (i.e., textual borrowing) differing from those prevalent in Anglo American academia and clearly punitive stances on perceived plagiarism. These results suggest the need to take an educative rather than punitive approach to source use in English academic writing.     

熟练潮-普双言者的语义通达机制:来自通道比较的证据

采用跨语言启动的范畴判断范式,通过2个实验,考察了熟练潮-普双言者在听觉通道内和听-视跨通道条件下的语义通达机制。结果发现,无论是以潮州话词语为启动词,还是以普通话词语为启动词,当词对具有高语义相关时,启动词均对目标词产生了显著的跨语言启动效应;在听觉通道内,两种语言之间的启动量无差异,而在听-视跨通道条件下,L2对L1的启动量显著大于L1对L2的启动量。这些结果表明,熟练潮-普双言者共享语义(概念)表征,词汇表征既相互独立又互相联系,L1与L2的词汇均能直接通达语义表征,但其联系强度及其相互之间的词汇表征联系强度均存在通道差异性。整个研究结果支持Kroll等人的修正分级模型。     

Judgment of infant cry: The roles of acoustic characteristics and sociodemographic characteristics

Adult judgments of infant cry are determined by both acoustic properties of the cry and listener sociodemographic characteristics. The main purpose of this research was to investigate how these two sources shape adult judgments of infant cry. We systematically manipulated both the acoustic properties of infant cries and contrasted listener sociodemographic characteristics. Then, we asked participants to listen to several acoustic manipulations of infant cries and to judge the level of distress the infant was expressing and the level of distress participants felt when listening. Finally, as a contrasting condition, participants estimated the age of the crying infant. Using tree‐based models, we found that judgments of the level of distress the infant was expressing as well as the level of distress listeners felt are mainly accounted for by select acoustic properties of infant cry (proportion of sound/pause, fundamental frequency, and number of utterances), whereas age estimates of a crying infant are determined mainly by listener sociodemographic characteristics (gender and parental status). Implications for understanding infant cry and its effects as well as early caregiver‐infant interactions are discussed.     

医事法学人才培养模式20年之进展

经过近二十年的积累,我国医事法学的人才培养在很多方面取得了长足的进展。全国有50余所高校开设了该专业方向,实现了从专科生到研究生的宽跨度培养。培养既懂医又懂法,且能在相关机构从事与医疗卫生活动相关的立法、司法与执法工作的复合型人才成为各院校共同的培养目标。包括医学基础课、法学基础课和专业特色课在内的理论课与包括医学实习和法学实践在内的实践课构成了医事法学的课程体系。从事医事法学研究的文献逐年增多。一支专业的师资队伍正在形成。     

初始信念、组织诱引对员工心理契约变化的影响

心理契约是员工——组织关系的重要形式,组织中的心理契约是发展变化的。该研究采用追踪设计,以189名大学本科毕业生为研究对象,考察员工入职前初始信念和入职后组织提供的诱引因素以及两者之间的交互作用如何影响员工对组织义务感的改变。研究发现：组织支持对关系型义务感和交易型义务感的变化都有明显的影响作用,其对关系型义务感的影响强于对交易型义务感的影响;员工入职前初始信念对员工义务感发展的影响作用受到组织诱引包括工作奖赏和组织支持的调节     

基于心理学视域的冥想研究

冥想(meditation)是一些综合性的心理和行为训练, 它有助于个体建立一种特殊的注意机制, 达到心理上的整体提升。心理学目前对冥想的研究主要集中在冥想的脑机制及冥想的功能(心理恢复、心理发展)两个方面, 常使用的研究工具主要有量表和EEG、fMRI、SPECT等仪器设备。未来的冥想研究应该在进一步规范冥想训练技术的基础上, 侧重于各种冥想技术的比较并对冥想结果开展长期的跟踪研究。
