摘要

摘要为了研究语际同音词（ILHP）单词处理的神经动力学，我们创建了一个由土耳其语对照词和土耳其文/英语ILHP单词组成的单词列表，并要求母语为土耳其语的人在用fNIRS记录他们的前额叶活动时执行以下任务之一：被动听力；单词识别；单词记忆。我们发现左侧DLPFC在所有任务中都处于活动状态。在ILHP单词识别任务期间，右侧DLPFC活动增加，这可能是由于用于冲突监控的域通用控制网络，而在ILHP的单词记忆任务中，左侧DLPFC活动增加，可能是由于与工作内存相关的过程。这些发现表明，ILHP处理诱导了大脑中语言之间的竞争，支持BIA+模型，并且右侧DLPFC可能是BIA+模式的任务/决策系统的一部分。最后，目前的研究结果表明，任务要求可以调节大脑活动的位置和幅度。

Auditory processing of interlingual homophones: an fNIRS investigation

ABSTRACT To examine the neural dynamics of interlingual homophone (ILHP) word processing, we created a word list consisting of Turkish control and Turkish/English ILHP words and asked native Turkish speakers to perform one of the following tasks while their prefrontal activity was recorded with fNIRS: passive listening; word recognition; word memorisation. We found that left DLPFC was active during all tasks. The right DLPFC activity was increased during ILHP word recognition task possibly due to domain-general control networks for conflict monitoring, while the left DLPFC activity was increased for ILHP word memorisation task possibly due to the working memory related processes. These findings suggest that ILHP processing induce a competition between languages in the brain, supporting the BIA+ model and that right DLPFC could be part of the task/decision system of BIA+ model. Lastly, current findings suggest that task requirements can modulate the location and the magnitude of the brain activity.

期刊介绍： Language, Cognition and Neuroscience (formerly titled Language and Cognitive Processes) publishes high-quality papers taking an interdisciplinary approach to the study of brain and language, and promotes studies that integrate cognitive theoretical accounts of language and its neural bases. We publish both high quality, theoretically-motivated cognitive behavioural studies of language function, and papers which integrate cognitive theoretical accounts of language with its neurobiological foundations. The study of language function from a cognitive neuroscience perspective has attracted intensive research interest over the last 20 years, and the development of neuroscience methodologies has significantly broadened the empirical scope of all language research. Both hemodynamic imaging and electrophysiological approaches provide new perspectives on the representation and processing of language, and place important constraints on the development of theoretical accounts of language function and its neurobiological context.
