Visualizing the functional connectivity of bilingual and monolingual brain during multitasking

摘要

A majority of study has suggested that bilinguals are different from monolinguals in their cognitive processing but with the lack of neuro-scientific validation. Moreover the psychological studies have suggested that bilinguals are inherently better at multitasking when compared with the performance of monolinguals owing to the fact that they are used to the act of switching between language conflicts. The present study aims to support this hypothesis with results from neurological study. Twenty healthy, right handed adults were employed while performing task and analysed using Electroencephalography (EEG). When the cognitive load on the brain is increased there is a surge in connectivity among different electrodes to execute the task and hence performance will be deprecated. However, since bilinguals are inherent multi taskers, they did not face much difficulty while performing the task and did not feel loaded. This suggests that the language centres in the brain are involved in cognitive processing and execution of information and concludes the hypothesis that bilinguals outperform monolinguals while multitasking.
