How to learn more about how children learn languages: A commentary on Kidd and Garcia (2022)

Kidd and Garcia demonstrate that the field of language acquisition must consider a more diverse range of languages. This is certainly needed, to gain a deeper understanding of the basic mechanisms of language acquisition; to achieve that, we need more longitudinal studies of several children per language, with (trained) fluent-user transcription and analysis. This could, for example, help to establish the size of the unit from which the child extracts generalizations and builds categories and networks in phonological development.
