Abstract
When speaking and listening, bilinguals have the ability to seamlessly switch between their two languages using complex control processes. In the present study, we use electroencephalography (EEG) and time-frequency representation (TFR) analyses to investigate comprehension-based switching between experienced and newly learned languages. Bilinguals performed an auditory picture-word matching task in two experienced languages (Chinese and English) and in two newly learned languages (German and Japanese). The behavioral results revealed asymmetrical switch costs when switching between experienced languages, with larger costs in Chinese than in English, but no costs between the two newly learned languages. The results of the TFR analyses found that for the experienced languages, switch trials induced a power decrease in delta and theta bands, while for the two newly learned languages, switch trials led to a power decrease in the theta and alpha bands. The findings underscore the dynamic nature of language control and provide evidence for the Dynamic Restructuring Model.
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.
