Elizabeth Schoen Simmons; Rhea Paul – Journal of Speech, Language, and Hearing Research, 2025
Purpose: The lexical selection hypothesis posits that first words added to a toddler's spoken vocabulary will be predominantly those beginning with early developing consonant phonemes. Using this framework, we evaluated the relationship between word form and lexical selection among late talkers and two typical comparison groups. Method: An online…

Daniela Avelar; Britt Singletary; Philip S. Dale; Laura M. Justice – Journal of Speech, Language, and Hearing Research, 2025
Purpose: Children who have late language emergence, or are late talkers (LTs), have substantially lower vocabulary levels than their peers, on average. Notably, differences in how researchers define "who" comprises LTs can lead to inconsistencies across findings. The current study examined how the number of children identified as LTs…

Hila Gendler-Shalev; Rama Novogrodsky – First Language, 2024
Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…

Eriksson, Mårten – International Journal of Language & Communication Disorders, 2023
Background: The Language Development Survey (LDS) and the MacArthur-Bates Communicative Development Inventories (MB-CDI) are two parental report forms that have been productive in providing data on early child language during the past 30 years. The instruments have been used both in studies relating to typical developing children and in screening…

Jiménez, Eva; Hills, Thomas T. – Developmental Psychology, 2023
The present study investigates the relation between language environment and language delay in 63 British-English speaking children (19 typical talkers (TT), 22 late talkers (LT), and 22 late bloomers (LB) aged 13 to 18 months. Families audio recorded daily routines and marked the new words their child produced over a period of 6 months. To…

Horvath, Sabrina; Kueser, Justin B.; Kelly, Jaelyn; Borovsky, Arielle – Language Learning and Development, 2022
While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…
