Day, Trevor K. M.; Elison, Jed T. – Journal of Child Language, 2022
A critical question in the study of language development is to understand lexical and syntactic acquisition, which play different roles in speech to the extent it would be natural to surmise they are acquired differently. As measured through the comprehension and production of closed-class words, syntactic ability emerges at roughly the 400-word…

Haebig, Eileen; Jiménez, Eva; Cox, Christopher R.; Hills, Thomas T. – Autism: The International Journal of Research and Practice, 2021

We also examined social features…

Lukyanenko, Cynthia; Conroy, Anastasia; Lidz, Jeffrey – Language Learning and Development, 2014
In this study we investigate young children's knowledge of syntactic constraints on Noun Phrase reference by testing 30-month-olds' interpretation of two types of transitive sentences. In a preferential looking task, we find that children prefer different interpretations for transitive sentences whose object NP is a name (e.g., "She's patting…

Data were first gathered from parents on the CDI-SF vocabulary scores for seventy-six…
