The relationship of rapid serial naming and word reading in normally developing readers: An exploratory model     

Cutting  Laurie E.  Denckla  Martha Bridge 《Reading and writing》2001,14(7-8):673-705

Even though researchers have established that rapid serial naming (RSN), or the ability to name within a restricted category of visual stimuli quickly, is a significant predictor of word reading, the predictive nature of RSN is not well understood. To investigate the relationship of RSN and other variables thought to contribute to beginning word reading (phonological awareness, orthographic knowledge, memory span, processing speed, and articulation), a preliminary/exploratory model of word reading was developed and then tested by path analysis. Results indicated that no variable in the model could fully `explain' RSN; processing speed, but not articulation, contributed to RSN performance. RSN and orthographic knowledge were significantly related, but this relationship was due to the effects of processing speed. In terms of their unique contributions to the variance in word reading, RSN, phonological awareness, and orthographic knowledge were independent of each other. While these results pertain only to normal readers and are preliminary in nature, they may provide a basis for a clear interpretation of similar studies conducted with both normal and dyslexic readers.  相似文献   

应用过定位实现零件的高精度加工     

刘越 《九江职业技术学院学报》2003,(4):11-13

过定位属违反工件定位原理的一种定位方式，使用不当或破坏工件的正确定位，会影响加工精度或造成干涉使工件无法安装；如若处理得好，过定位不仅能提高工件的定位精度，还能提高工件的安装刚度。本从工程实际出发，介绍一种过定位的具体应用。  相似文献

Context effects and the processing of spoken homophones     

Li  Ping  Yip  Michael C. 《Reading and writing》1998,10(3-5):223-243

This study examined the role of context effects in the processing of homophones in Chinese and Chinese-English bilingual speech. In Experiment 1, Chinese speakers were presented with successively gated portions of a homophone in a sentence context, and they identified the homophone on the basis of its increasing acoustic information. In Experiment 2, Chinese-English bilinguals were presented with a cross-language homophone in a sentence context, and they named a visual probe that had or did not have phonological overlaps with the homophone. Results indicate that prior sentence context has an early effect on the disambiguation of various homophone meanings, shortly after the acoustic onset of the word, in both monolingual and bilingual situations. The results are accounted for by interactive activation models of lexical processing, in which the recognition of a homophone is a result of the interactions among phonological, lexical, and contextual information at an early stage.  相似文献

台湾出口加工区与大陆保税区功能转型比较   总被引：3，自引：0，他引：3  

李友华  陈曜 《安徽师范大学学报(人文社会科学版)》2005,33(1):47-53

中国大陆保税区目前已经发展到向自由贸易区转型的关键阶段。大陆保税区与台湾出口加工区的转型存有某些共性:缺乏资本、资源、技术等要素而拥有廉价劳动力;以加工业为主导产业并处于制造业中心转移历史机遇中;在发展后期面临劳动力成本上涨、竞争加剧、产业空洞化问题;功能开发向多元化方向发展等。台湾出口加工区的成功转型对大陆保税区功能转型具有借鉴意义。  相似文献
