Abstract

Previous work has shown that experience speaking more than one language in childhood is associated with decreased intra-individual neural variability in electrophysiological responses during a low-level speech perception task. However, no study has yet evaluated the impact of dual language experience on variability in fMRI responses during a higher-level spoken and written language processing task. In the current study, we calculated trial-by-trial variability in neural activation during an fMRI task that involved deciding whether spoken or printed English words matched pictures of items. We compared trial-by-trial neural activation variability between two groups of 8-15 year-old children: a group of dual language learners (N = 24; 11 female) who were Spanish-dominant and acquiring English, and a group of monolingual learners who were English-dominant (N = 17; 9 female). We found that when controlling for a variety of language, general cognitive, and demographic measures, neural activation variability for printed words was greater in the dual language learners compared to the monolingual learners in the right middle frontal gyrus, a brain region previously associated with attentional control. This finding highlights how neural ...Continue Reading
