我们考察了在语际同形词语义启动的情况下，词汇识别过程中跨语言激活的时间进程。西语-英语双语者被呈现在视觉上的英语单词对，一次一个单词，并在记录事件相关电位的同时判断这两个单词在意义上是否相关。语际同形异义词(例如，“派”：西班牙语中的“派”是脚。)出现在目标位置，前缀是与英语意义相关(例如，“Apple”)、与西班牙语意义有关的语际同形异义词(例如，“Toe”)或完全不相关的质数(例如，“Floor”/“Bed”)。西语-英语双语者不仅在语际同形异义词与英语意义相关时，而且在与质数的西班牙语意义相关时，也表现出语义启动。这些启动效应可以在N400的平均幅度(350-500 ms)中检测到，即使目标词与西班牙语中的质数有关，实验的背景是英语。然而，只有与英语相关的刺激对才能在晚正成分(Lpc；550-700 ms)的窗口内发现关联效应。为了验证观察到的结果模式是由于参与者的双语能力，我们还测试了一组只会说英语的人。只有当语际同形异义词与英语意义相关时，单语者才对N400和LPC时间窗表现出语义启动效应。这些结果表明，两种语言都是在以N400调制为索引的语义激活的经典时间框架内被激活的，但非目的语中的语义激活没有被明确地处理。
We examined the time course of cross-language activation during word recognition in the context of semantic priming with interlingual homographs. Spanish–English bilinguals were presented pairs of English words visually one word at a time and judged whether the two words were related in meaning while recording event-related potentials. Interlingual homographs (e.g., “pie”: “Pie” in Spanish is a foot.) appeared in the target position and were preceded by primes that were either related to the English meaning (e.g., “apple”), related to the Spanish meaning of interlingual homographs (e.g., “toe”) or totally unrelated (e.g., “floor”/“bed”). Spanish–English bilinguals showed semantic priming not only when interlingual homographs were related to the English meaning but also to the Spanish meaning of the prime. These priming effects were detectable in the mean amplitude of the N400 (350–500 ms) even when the target word was related to the prime in Spanish and the context of the experiment was English. However, the relatedness effect was found in the window of a late positive component (LPC; 550–700 ms) only for stimulus pairs related in English. To verify that the observed pattern of the results was due to participants’ bilingualism, we also tested a group of English monolinguals. The monolinguals showed a semantic priming effect for the N400 and LPC time windows only when interlingual homographs were related to the English meaning. These results suggest that both languages are activated in the classical time frame of semantic activation indexed by N400 modulations, but that semantic activation in the non-target language failed to be explicitly processed.
