This study examines how children process the speech envelope, a key acoustic feature of language. Brain data from ages 4–18 reveal a developmental shift from left- to right-hemisphere processing. This newly identified trajectory may help detect language impairments and improve early interventions in speech and language development.

This research investigates why children struggle to learn pronouns and why these difficulties vary across languages. Through cross-linguistic experiments and eye-tracking, it shows that pronouns pose an intrinsic processing challenge. Some languages compensate for this difficulty, offering new insights into language development and human learning.
