Doctoral Dissertation Research: Mapping Orthography-to-Phonology in Bilingual Word Reading

在国家科学基金会的支持下，Mona Roxana Botezatu女士将在Carol Miller博士和Maya Misra博士的指导下为她的博士论文收集数据。这项研究将评估双语者第一语言和第二语言在字母-声音映射上的差异如何影响第二语言的阅读。过去的研究表明，单词阅读技能会在书写系统之间转移，双语者会经历两个印刷体-声音系统之间的竞争。共享同一手稿的语言，如英语和西班牙语，在拼写发音一致性或给定字母簇可用发音的数量上有所不同(例如，一致：Hair，Pair中的“-air”；不一致：Most中的“-ost”，Cost)。这些差异已经被证明会影响单词阅读策略。本研究调查了双语者在阅读拼写发音一致性与第一语言不同的第二语言时的单词阅读策略的迁移。在一系列的五个实验中，这个问题将通过比较以英语为母语的人和西班牙-英语、荷兰-英语和汉英双语者在一项英语视觉押韵判断任务中的表现来检验。这项任务要求个体对视觉呈现的单词对进行押韵判断，而刺激的拼写-声音一致性是有系统地不同的。为了测试在同一任务中同时使用两种语言时，单词阅读策略是否会更有力地迁移，荷兰-英语双语者还将接受荷兰-英语押韵判断任务的测试。本研究的目的是利用行为和神经认知方法(事件相关电位)提供统一的证据，以更好地理解母语阅读策略对熟练英语阅读的影响。研究结果将为调整当前的单字阅读模式以适应双语词典提供重要的启示，并最终将指导针对英语学习者的识字教学实践。

With the National Science Foundation support, Ms. Mona Roxana Botezatu will collect data for her doctoral dissertation under the direction of Drs. Carol Miller and Maya Misra. This research will evaluate how differences in letter-sound mapping between a bilingual's first and second languages impact reading in the second language. Past research suggests that word reading skills transfer across writing systems and that bilinguals experience competition between their two print-sound systems. Languages that share a script, such as English and Spanish, differ in their spelling-sound consistency, or the number of pronunciations available for given letter clusters (e.g., consistent: the "-air" in hair, pair; inconsistent: the "-ost" in most, cost). These differences have been shown to affect word-reading strategies. The present research investigates transfer of word-reading strategies in bilinguals who read a second language that differs in spelling-sound consistency from their first language. In a series of five experiments, this issue will be examined by comparing performance across native English speakers and Spanish-English, Dutch-English and Chinese-English bilinguals on an English visual rhyme judgment task. The task requires individuals to make rhyme judgments of visually presented word pairs, while the spelling-sound consistency of the stimuli is varied systematically. To test whether word-reading strategies transfer more robustly when both languages are used within a single task, Dutch-English bilinguals will also be tested on a Dutch-English rhyme judgment task. The goal of this research is to provide converging evidence using behavioral and neurocognitive methods (event-related potentials) to better understand the consequences of native language reading strategy for skilled reading in English. Results will provide critical implications for adapting current models of single word reading to the bilingual lexicon and will ultimately inform literacy instruction practices targeting English language learners.
