Abstract

In the present study, Chinese–English bilinguals were asked to name English words in a delayed word naming task while recording the ERP data. We explored the interactions between age of acquisition (AoA) of second language (L2) words and other variables to examine the origins of L2 AoA effects. The results showed significant L2 AoA effects on N400 and LPC, with larger N400 and smaller LPC for later-acquired L2 words. On N170, the L2 AoA effect was modulated by the orthographic neighbourhood size and the spelling–sound onset consistency in the left hemisphere. That is, the L2 AoA effect was significant for words with fewer neighbours and inconsistent mappings but not for words with more neighbours and consistent mappings. Our results showed that L2 AoA has an early and long-lasting influence on word naming, and these effects arise from both spelling–sound connections and semantic representation. These findings support an integrated view of the Semantic and Arbitrary Mapping Hypotheses.

单词命名任务中的二语习得年龄效应:ERP数据的回归分析
在本研究中,中英双语者被要求在一个延迟单词命名任务中命名英语单词,同时记录ERP数据。本研究探讨了二语词汇习得年龄(AoA)与其他变量之间的相互作用,以探讨二语词汇习得年龄效应的起源。结果表明,第二语言AoA对N400和LPC有显著影响,后习得的第二语言单词N400较大,LPC较小。在N170上,L2的AoA效应受正字法邻域大小和左半球拼写-发音开始一致性的调节。也就是说,L2 AoA效应对于具有较少邻居和不一致映射的单词显著,而对于具有较多邻居和一致映射的单词则不显著。我们的研究结果表明,第二语言的AoA对单词命名有早期和持久的影响,这些影响来自拼写-声音连接和语义表征。这些发现支持语义和任意映射假说的综合观点。

期刊介绍: The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
