摘要

事件相关电位(ERP)技术为区分不同的语言过程提供了一种时间上准确的测量方法。在这里,我们测量了24个月大的法语学习儿童对已知单词、假单词和非单词的反应,以研究在听力任务中,个人词汇技能如何影响对母语和非母语单词的处理。假词的N200比非词更明显,而已知词和假词之间没有差异。然而,已知词和伪词之间的振幅差异与生产性词汇有关。词汇量得分高的幼儿比词汇量得分低的幼儿表现出更大的差异。同样,对于正面分布的晚期消极性,只有词汇知识较高的幼儿对三种词汇类型的反应表现出梯度模式,而词汇技能较低的儿童对每种词汇类型的反应表现出相似的反应。我们的研究结果表明,在非参考听力任务中,词汇技能对母语和非母语词汇的脑信号量有影响。

Brain signatures of native and non-native words in French-learning 24-month-olds: The effect of vocabulary skills

The event-related potential (ERP) technique provides a temporally accurate measure to distinguish among different linguistic processes. Here, we measured ERPs in response to known words, pseudowords and nonwords in 24-month-old French-learning children to investigate how individual vocabulary skills contribute to the processing of native-like and non-native-like words during a listening task. The N200 was more pronounced for pseudowords than for nonwords while no difference was found between known words and pseudowords. The amplitude difference between known words and pseudowords was, however, correlated with the productive vocabulary. Toddlers with a higher vocabulary score exhibited a bigger difference than toddlers with a lower vocabulary score. Similarly for the frontally distributed late negativity, only those toddlers with higher vocabulary knowledge exhibited a gradient pattern of activity in response to three word types while children with lower vocabulary skills exhibited a similar responsiveness to each word type. Our results suggest that vocabulary skills contribute to the magnitudes of brain signals in response to native and non-native words in a non-referential listening task.

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.
