对单语儿童进行的在线理解测量研究表明，口语识别的速度和准确性与词汇发展相关。在这里，我们考察了学习西班牙语和英语的双语儿童(n=26；2；6岁)的语音处理效率与词汇发展的关系。语言之间的联系很弱：西班牙语的词汇量与英语的词汇量不相关，儿童在线理解西班牙语的能力与他们的英语能力无关。相反，在控制了另一种语言的处理速度和词汇量后，一种语言的在线加工效率与该语言的词汇量显著相关。双语者词汇获取效率和词汇知识之间的这种联系与以前对西班牙语和英语单语者的研究结果类似，这表明儿童从构建工作词典的输入中提取信息的能力基本上与语言构建的机制有关。
Research using online comprehension measures with monolingual children shows that speed and accuracy of spoken word recognition are correlated with lexical development. Here we examined speech processing efficiency in relation to vocabulary development in bilingual children learning both Spanish and English (n=26; 2;6 yrs). Between-language associations were weak: vocabulary size in Spanish was uncorrelated with vocabulary in English, and children’s facility in online comprehension in Spanish was unrelated to their facility in English. Instead, efficiency of online processing in one language was significantly related to vocabulary size in that language, after controlling for processing speed and vocabulary size in the other language. These links between efficiency of lexical access and vocabulary knowledge in bilinguals parallel those previously reported for Spanish and English monolinguals, suggesting that children’s ability to abstract information from the input in building a working lexicon relates fundamentally to mechanisms underlying the construction of language.
