Neurocognitive Mechanisms of Language Switching in Bilinguals: Insights from the Dynamic Restructuring Model

Abstract

Code switching refers to the speakers’ ability to switch between languages proficiently. Many internally generated and external factors are responsible for process of code switching. The current study aims to find out the neurocognitive mechanisms involved in the process of code switching in bilinguals. The study is based on qualitative and quantitative data. A small sample size of only 6 participants aging between 20 to 25 years is selected purposively. The data are collected with the help of recording conversation of the participants in different conversation contexts i.e. formal and informal contexts for process of code switching. Similarly, Quantitative data are collected through Frequency Magnetic Resonance Imaging (fMRI) in order to record which parts of the brain are involved in the process of code-switching. The data are analyzed with the help of Dynamic Reconstruction Model and Diffusion Tensor Imaging (DFI) technique. The findings have shown that the proficiency of languages, contexts of conversation and cognitive load are responsible for a smooth code switching.
