本研究采用语义启动范式，考察了语义语境和词汇正字图形语境对语际同形词反应时(RTS)和事件相关电位(ERPs)的影响。荷兰-英语双语者进行了一项英语词汇判断任务，在这项任务中，像STEM(在荷兰语中的意思是“声音”)这样的同形异义词前面有像词根或傻瓜这样的前缀，这些词在语义上与目标单词的英语阅读相关或无关。同形异形词在语义相关的素数后面的反应比在不相关的素数后面更快。两种情况下的反应都受到两种读音的相对频率的调节：当英语单词频率较高或荷兰语单词频率较低时，反应速度较快。在事件相关电位中，N400效应被用来反映语义整合的过程，在相关启动词之前的同形异义词被发现。值得注意的是，在第一语言(荷兰语，L1)和第二语言(英语，L2)中，N400效应的幅度也受到词频的调节。观察到的词汇变量和语义变量之间的关系支持双语语义启动模型，该模型扩展了用于双语单词识别的语言非选择性BIA+模型。(C)2005 Elsevier B.V.保留所有权利。
Using a semantic priming paradigm, this study examines the effects of semantic and lexical-ortho graphic context on reaction times (RTs) and event-related potentials (ERPs) for interlingual homographs. Dutch-English bilinguals performed an English lexical decision task in which homographs like STEM (meaning "voice" in Dutch) were preceded by primes like ROOT or FOOL that were semantically related or unrelated to the English reading of the target word. Homographs were responded to faster following semantically related primes than following unrelated primes. The responses in both conditions were modulated by the relative frequencies of the two readings of the homographs: responses were faster when their English word frequency was high or when their Dutch word frequency was low. In the ERPs, N400 effects, taken to reflect processes of semantic integration, were found for homographs preceded by related primes. Remarkably, the amplitude of the N400 effect was also modulated by word frequency in both the first (Dutch, L1) and the second (English, L2) language. The observed relationship between lexical and semantic variables supports a model for bilingual semantic priming that extends the language nonselective BIA+ model for bilingual word recognition.
