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进展，但关于双语在词汇处理的正字法、语音和语义层面上引起微妙变化的方式，仍有许多有待了解的地方。本研究项目旨在修正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)非目标语言信息对视觉和口语识别的影响；(b)说话者的特征（如熟练程度、习得年龄）如何改变双语对语言加工的影响；(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，我们使用行为和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:
