Diverse Sounds: How Prenatal Language Experience Shapes Fetal Brain Development and Later Language Learning. A Longitudinal Study.

Project description

Prenatal language shapes fetal brain development

Long before a child speaks a first word, the brain is already tuning itself to language. The prenatal period is critical for shaping the neural circuits that support communication and cognition, yet how exposure to language in the womb influences later learning remains poorly understood, especially in multilingual settings. The ERC-funded DiverseSounds project aims to study how prenatal language environments shape early brain plasticity and language development. Combining neuroscience, linguistics, and information theory, the project studies how foetuses process speech and how early neural responses and neuroplasticity predict language learning from 25 weeks of gestation through the first six months of life. DiverseSounds could inform early diagnosis, language therapy, and public health strategies.

Objective

The prenatal period represents a critical window in which key neural structures and functions are shaped, laying the foundation for sensory processing, language learning, and cognitive function throughout an individual's lifetime. While research recognizes the importance of prenatal auditory and language stimulation, it is unclear whether and to what degree the language environment in utero shapes the fetal brain and language acquisition after birth. This proposal will focus on the prenatal language environment and its effects on neural plasticity and language development. We will adopt a longitudinal approach combining developmental cognitive neuroscience, linguistics, and information theory, using both novel and existing data.

Given the diversity of speech sounds across languages, multilingualism provides an excellent frame-work for studying environmental effects on early learning in typical development. DiverseSounds will investigate input-driven neuroplasticity of fetal brain organization, assess which characteristics of speech are processed by human fetuses, determine fetal neural predictors of inter-individual differ-ences in speech sound perception in early infancy, and investigate if fetal neuroplasticity longitudinally predicts language learning mechanisms in infancy.

We will use state-of-the-art brain imaging techniques (MRI and EEG) in monolinguals and multilin-guals, and novel measures of phonological diversity informed by descriptive and typological linguistic work. We propose to examine the relationship between prenatal experience and subsequent develop-mental trajectories of language acquisition from 25 weeks of gestation to 6 months of age. This re-search will advance our understanding of fetal and infant development and therefore bears significant implications for theory building, language therapy, and public health policy.
