Abstract
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.
