Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Cynthia Core; Joanna Pfister; Rosario Rumiche; Erika Hoff – International Journal of Behavioral Development, 2025
We investigated the role of bilingual parents' language proficiency in their reports of their children's vocabulary size. Sixty-four Spanish-English bilingual mothers whose L1 was Spanish reported their bilingual children's English and Spanish vocabularies and 37 monolingual L1 English-speaking mothers reported their monolingual children's English…

Miranda Gómez Díaz; Laia Fibla; Rachel Ka-Ying Tsui; Krista Byers-Heinlein – Developmental Psychology, 2024
Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

Artis, Jonet; Arunachalam, Sudha – Journal of Speech, Language, and Hearing Research, 2023
Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

Chelsea La Valle; Gabriela Davila Mejia; Carol L. Wilkinson; Nicole Baumer – Journal of Speech, Language, and Hearing Research, 2025
Purpose: Toddlers with Down syndrome (DS) showcase comparable or higher rates of gestures than chronological age-- and language-matched toddlers without DS. Little is known about how gesture use in toddlers with DS relates to multiple domains of development, including motor, pragmatics, language, and visual reception (VR) skills. Unexplored is…

Golnoosh Golmohammadi; Farhad Sakhai; Faezeh Asadollahpour; Kiana Nouhi; Naemeh Jafari; Zahra Baghejari – First Language, 2024
This study aimed to adapt and validate the Word Complexity Measure (WCM) for Persian-speaking toddlers. The WCM is a tool for assessing phonological complexity, originally proposed by Stoel-Gammon. The study was conducted in two phases: (1) adapting the WCM parameters to the Persian language and (2) conducting a validation study with 60…

Word Imageability Is Associated with Expressive Vocabulary in Children with Autism Spectrum Disorder
Lin, Kimberly R.; Wisman Weil, Lisa; Thurm, Audrey; Lord, Catherine; Luyster, Rhiannon J. – Autism & Developmental Language Impairments, 2022
Background & aims: Throughout typical development, children prioritize different perceptual, social, and linguistic cues to learn words. The earliest acquired words are often those that are perceptually salient and highly imageable. Imageability, the ease in which a word evokes a mental image, is a strong predictor for word age of acquisition…

Nieto, Carmen; Campos, Ruth – Early Child Development and Care, 2022
The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

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…

Lorang, Emily; Hanania, Alexandra; Venker, Courtney E. – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Using a novel parent report measure, this study investigated whether asking parents to rate their certainty when reporting on child vocabulary skills provided additional insight into parent report and emerging language abilities in young autistic children. Specifically, we investigated whether parent certainty varied based on whether the…

Kirby; Bahar Keceli-Kaysili; Tiffany G. Woynaroski – Journal of Autism and Developmental Disorders, 2024
Early differences in sensory responsiveness may contribute to difficulties with communication among autistic children; however, this theory has not been longitudinally assessed in infants at increased familial versus general population-level likelihood for autism (Sibs-autism vs. Sibs-NA) using a comprehensive battery of sensory responsiveness and…

Purpose: Caregivers of autistic children present with high stress levels, which have been associated with poorer child outcomes in several domains, including language development. However, prior to this study, it was unknown whether elevated caregiver stress was associated with language development in infant siblings of autistic children…

Clark, Grace T.; Reuterskiöld, Christina – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Previous research has demonstrated that typically developing children, verbal children with a diagnosis of autism, children with Down syndrome, children with developmental language disorder, and children with dyslexia can all benefit from orthographic support during word learning tasks. This study sought to determine if minimally speaking…

Maes, Pauline; Weyland, Marielle; Kissine, Mikhail – Autism: The International Journal of Research and Practice, 2023
In many autistic children, speech onset is delayed and expressive language emerges after 3 years of age. We qualitatively and quantitatively describe oral productions of autistic preschoolers, including many non- or minimally speaking, recorded during interactions with a caregiver and with an experimenter. Data clustering on manually coded oral…

Robert Brinton Fujiki; Kari M. Lien; John Munday; Susan L. Thibeault – Journal of Speech, Language, and Hearing Research, 2024
Purpose: The purpose of this study was to examine the influence of socioeconomic deprivation on language and developmental outcomes in toddlers with cleft palate with or without cleft lip (CP ± L). Other factors known to influence language outcomes were also considered, including home language history, history of hearing problems, syndromic…
