Converging evidence of the impact of bilingualism on the brain’s pragmatic language network

Abstract: Pragmatic language—the ability to understand and use language in social contexts—is a complex linguistic skill critical for effective social interactions. It involves interpreting indirect requests, figurative language, and relies on integrating linguistic, social, and contextual cues. While pragmatic language difficulties are common in neurodevelopmental disorders such as autism, emerging research suggests that bilingualism may enhance cognitive and social skills relevant to pragmatic competence. However, the neural mechanisms of bilingualism, and its influence on pragmatic language remain poorly understood. To address this, we conducted a multi-method investigation integrating a PRISMA-guided systematic review, meta-analyses using the open database Neurosynth, and an empirical analysis of the open neuroimaging data, OpenNeuro. The Neurosynth meta-analyses on the terms “communication,” “social cognition,” and “bilinguals”, identified consistent involvement of the bilateral insula, left inferior frontal gyrus (IFG), fusiform gyrus, and posterior cingulate cortex. An analysis of resting-state fMRI data from early bilinguals, late bilinguals, and monolinguals using OpenNeuro revealed early bilinguals showing decreased functional connectivity within core pragmatic language regions, including IFG, superior and middle temporal gyrus, and supramarginal gyrus, suggesting enhanced neural efficiency derived from dual-language management. These findings provide evidence that bilingualism may reshape the neural architecture underlying pragmatic language comprehension. By highlighting how language experience influences brain networks involved in social communication, this work has implications for both cognitive neuroscience and interventions targeting pragmatic deficits, particularly in clinical populations such as individuals with autism.
