Tasks of word reading in Chinese and English; nonverbal IQ; speeded naming; and units of syllable onset (a phoneme measure), syllable, and tone detection awareness were administered to 211 Hong Kong Chinese children ages 4 and 5. In separate regression equations, syllable awareness was equally associated with Chinese and English word recognition. In contrast, syllable onset awareness was uniquely associated with English reading only, whereas tone detection was uniquely associated with Chinese reading only. Results underscore both the universality of first-language phonological transfer to second-language reading and the importance of different psycholinguistic units (Ziegler & Goswami, 2005) for understanding reading acquisition: Tone units are integral to Chinese character recognition, whereas phonemes are more strongly associated with English word recognition, even within the same children. 相似文献

This 1-year longitudinal study examined the extent to which morphological awareness, orthographic knowledge, and phonological awareness, along with speeded naming, uniquely explained word recognition, dictation (i.e., spelling), and reading comprehension among 171 young Hong Kong Chinese children. With age and vocabulary knowledge statistically controlled, both morphological awareness and orthographic knowledge were uniquely associated with all three concurrently measured literacy skills, as well as longitudinal measures of specific literacy skills. Naming speed was also uniquely associated with concurrent word reading, as well as all three literacy skills longitudinally, even with their autoregressive effects controlled. Analyses of children's spelling mistakes indicated that 97% and 95% of all errors were either morpholexically or orthographically based at times 1 and 2, respectively. Morphologically based spelling errors were also uniquely associated with all three literacy skills across time. Findings underscore the importance of morphological awareness and orthographic knowledge for Chinese literacy acquisition. 相似文献

There were two goals of the present study. The first was to create a scoring scheme by which 9-year-old Chinese children??s writing compositions could be rated to form a total score for writing quality. The second was to examine cognitive correlates of writing quality at age 9 from measures administered at ages 6?C9. Age 9 writing compositions were scored using a 7-element rubric; following confirmatory factor analyses, 5 of these elements were retained to represent overall writing quality for subsequent analyses. Measures of vocabulary knowledge, Chinese word dictation, phonological awareness, speed of processing, speeded naming, and handwriting fluency at ages 6?C9 were all significantly associated with the obtained overall writing quality measure even when the statistical effect of age was removed. With vocabulary knowledge, dictation skill, age, gender, and phonological awareness included in a regression equation, 35% of the variance in age 9 writing quality was explained. With the variables of speed of processing, speeded naming, and handwriting fluency additionally included as a block, 12% additional variance in the equation was explained. In addition to gender, overall unique correlates of writing quality were dictation, speed of processing, and handwriting fluency, underscoring the importance of both general automaticity and specific writing fluency for writing quality development in children. 相似文献

有关网络等新媒体在时下高校共青团领域的运用一直是学界论争的焦点。秉承主客观相统一、主观认识能动地反映并影响客观存在的原则,通过分析网媒正反两方面影响所涵盖的新机遇和新挑战,认为高校共青团分类引导学生青年工作的合理路径是在巩固网媒平台自身建设并与传统媒体配套联动的基础上的,进一步明确主观认识、统筹要素资源、形成正面促进。 相似文献
