Electrophysiological and behavioural measures of bilingual lexical processing

虽然最近在确定双语对语言理解的影响方面取得了实质性的进展，但关于双语是如何引起词汇加工的拼写、语音和语义水平上的细微变化的，仍有许多有待理解的地方。本研究旨在修改单语视觉和口语识别时间过程的前沿模型，以考虑双语的影响，包括：(A)非目标语信息对视觉和口语识别的影响；(B)说话人特征(如熟练程度、习得年龄)如何改变双语对语言加工的影响；以及(C)双语者神经认知加工的变化对语言加工的影响。为了回答这些问题，我们使用了行为学和ERP方法。我们提出了三组实验来检验：

While substantial recent progress has been made in establishing the effects of bilingualism on language comprehension, much remains to be understood about the ways in which bilingualism gives rise to subtle alterations at orthographic, phonological and semantic levels of lexical processing. The present program of research aims to modify cutting-edge models of the timecourse of monolingual visual and spoken word recognition to take into account the effects of bilingualism, including: (a) the effects of non-target language information on visual and spoken word recognition; (b) the ways in which speaker characteristics (e.g., proficiency, age of acquisition) modify the effects of bilingualism on language processing; and (c) the impact on language processing of changes in neurocognitive processing in bilinguals. To answer these questions, we use behavioural and ERP methods. We propose three sets of experiments examining:
