The lab is structured around three research axes:

Kern, Sophie (2019). Language development in young children. De Boeck.
This book presents the development of language in young children in all its aspects: normal and pathological development, major phases of development, interindividual differences, etc.
It deals with current theories on language acquisition and the major stages of normal development: phonetic and phonological development, lexical development, morphosyntactic development, pragmatic development.
