Outline of Research at the Start

This project investigates the contribution of linguistic and social environmental factors on CP timing on multiple levels of language with a focus on perceptual attunement to native language speech sounds, by collecting dense longitudinal and cross-sectional datasets. These data will allow a precise understanding of environmental influences on CP timing in normally developing infants and to identify potential biomarkers of developmental delay, ultimately paving the way towards educational and clinical applications for iPlasticity.
