A resting-state EEG functional connectivity study examining the impact of linguistic experience on connectivity both pre- and post- cognitively demanding tasks.
Bilingualism has been found to have dynamic effects on cognition, brain structure, and brain function — following a non-linear trajectory throughout the lifespan. We are interested in examining the impact of bilingualism on brain function in different cognitive domains, and so administered three tasks to participants in between resting-state EEG recordings.
We used 3 cognitive domains based on previous research: language, attention/executive control, and domain-general. We will use the resting-state recordings to produce a functional connectivity analysis, which we will then model against level of bilingualism as measured using extensive language history questionnaires. The pre- and post-task connectivity patterns modulated by level of bilingualism will then be compared between the domains to determine whether there are any differences in the recruitment of brain regions used to complete the tasks.
Data collection has now finished and we are no longer recruiting.
