Mary Alt; Heidi M. Mettler; Elissa S. Schiff; Nora Evans-Reitz; Rebecca Burton; Sarah R. Cretcher; Allison Staib – Journal of Speech, Language, and Hearing Research, 2025
Purpose: The purpose of this study was to determine if the Vocabulary Acquisition and Usage for Late Talkers (VAULT) intervention could be efficaciously applied to a new treatment target: words a child neither understood nor said. We also assessed whether the type of context variability used to encourage semantic learning (i.e., action or object)…

Mettler, Heidi M.; Neiling, Sarah Lynn; Figueroa, Cecilia R.; Evans-Reitz, Nora; Alt, Mary – Journal of Speech, Language, and Hearing Research, 2023
Purpose: This feasibility study examined a caregiver-implemented telehealth model of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) protocol. We asked whether caregivers could reach fidelity on VAULT, if the protocol was socially and ecologically valid, and if late-talking toddlers could learn new words with this model. Method: Five…

Camilla E. Crawshaw; Carina Lüke; Ute Ritterfeld – Journal of Speech, Language, and Hearing Research, 2025
Purpose: Prior work has found that "late talkers" (LTs) as a group continue to demonstrate lower language and reading outcomes compared to their typically developing (TD) peers even into young adulthood. Others identified that children diagnosed with developmental language disorder (DLD) show difficulties later with theory of mind (ToM)…

Huei-Mei Liu; Feng-Ming Tsao; Chun-Yi Lin; Gwyneth Rost; Ling-Yu Guo – Journal of Speech, Language, and Hearing Research, 2023
Purpose: The current investigation evaluated the extent to which early noun, verb, and adjective lexicon sizes predicted later grammatical outcomes in Mandarin-speaking children with and without late language emergence (LLE) using a parent report. Method: In Study 1, the parents of 24 Mandarin-speaking children with typical language filled out the…

Curtis, Philip R.; Estabrook, Ryne; Roberts, Megan Y.; Weisleder, Adriana – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Late talkers (LTs) are a group of children who exhibit delays in language development without a known cause. Although a hallmark of LTs is a reduced expressive vocabulary, little is known about LTs' processing of semantic relations among words in their emerging vocabularies. This study uses an eye-tracking task to compare 2-year-old 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…

Perry, Lynn K.; Meltzer, Amy L.; Kucker, Sarah C. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Although children with hearing loss (HL) can benefit from cochlear implants (CIs) and hearing aids (HAs), they often show language delays. Moreover, little is known about the mechanisms by which children with HL learn words. One mechanism by which typically hearing (TH) children learn words is by acquiring word learning biases such as the…

Ratib Lekhal; May-Britt Drugli; Lisa Karlsen; Stian Lydersen; Elisabet Solheim Buøen – European Early Childhood Education Research Journal, 2024
This study examined the effectiveness of the "Thrive by Three" intervention for 1- to 3-year-old's language development. Data from 78 childcare centres, 187 toddler classrooms, and 1561 children (91.4% native Norwegian) were included. Results revealed that children in the intervention group had slightly steeper language development than…

Perry, Lynn K.; Kucker, Sarah C.; Horst, Jessica S.; Samuelson, Larissa K. – Developmental Science, 2023
Children with delays in expressive language (late talkers) have heterogeneous developmental trajectories. Some are late bloomers who eventually "catch-up," but others have persisting delays or are later diagnosed with developmental language disorder (DLD). Early in development it is unclear which children will belong to which group. We…

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. – Child Development, 2022
This study investigates the influence of semantic maturation on early lexical development by examining the impact of contextual diversity--known to influence semantic development--on word promotion from receptive to productive vocabularies (i.e., comprehension-expression gap). Study 1 compares the vocabularies of 3685 American-English-speaking…

Alt, Mary; Mettler, Heidi M.; Erikson, Jessie A.; Figueroa, Cecilia R.; Etters-Thomas, Sarah E.; Arizmendi, Genesis D.; Oglivie, Trianna – Journal of Speech, Language, and Hearing Research, 2020
Purpose: The aims of this study were (a) to assess the efficacy of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment and (b) to compare treatment outcomes for expressive vocabulary acquisition in late talkers in 2 conditions: 3 target words/90 doses per word per session versus 6 target words/45 doses per word per session.…

Hsin-Hui Lu; Wei-Chun Che; Yung-Hao Yang; Feng-Ming Tsao – International Journal of Language & Communication Disorders, 2024
Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

Lindsay R. Dennis; Kelly Farquharson; Anne C. Reed; Rebecca Summy; Kimberline G. Clark; Jennifer Westmoreland – Language, Speech, and Hearing Services in Schools, 2023
Purpose: This tutorial is designed for speech-language pathologists who supervise speech-language pathology assistants (SLP-As) and/ or paraeducators. SLP-As and paraeducators often support young children with disabilities within early childhood settings, but do not always have access to professional development to learn and/or enhance their skill…

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…
