This study compares the lexical composition of 118 children with autism spectrum disorder (ASD) aged 12 to 84 months with 4626 vocabulary-matched typically developing toddlers with and without language delay, aged 8 to 30 months. Children with ASD and late talkers showed a weaker noun bias. Additionally, differences were identified in the…

Meagher, Sean P.; Carlson, Betsy L.; Elrod, Marilisa G. – Journal of Autism and Developmental Disorders, 2021
Children referred for audiology evaluation due to speech and language delays represent a neurodevelopmentally high-risk group. The audiology evaluation is a behaviorally-challenging encounter early in the diagnostic process. We assessed interfering behaviors (IB) that complicated completion of audiometry as predictors of autism spectrum disorder…

Thurman, Angela John; Hoyos Alvarez, Cesar – Journal of Autism and Developmental Disorders, 2020
In the present study, language performance on standardized assessments (e.g., overall verbal performance, receptive and expressive vocabulary) and spontaneous language produced in play was compared between preschool-aged boys with autism spectrum disorder ([subscript n]ASD, n = 25) and boys with fragile X syndrome (FXS, n = 16). At the…

Yong, Yvonne H. L.; Dutt, Anuradha S.; Chen, Mo; Yeong, Adeline M. – Child Language Teaching and Therapy, 2021
This study compared a picture exchange (PE) system and an iPad®-based speech generating device (SGD) when teaching requesting skills to preschoolers with developmental disabilities and limited functional speech. A multiple baseline design with counterbalancing the order of two instruction conditions across participants was applied to compare the…

Boterberg, Sofie; Van Coster, Rudy; Roeyers, Herbert – Journal of Autism and Developmental Disorders, 2019
This study explored regression patterns in 100 children with ASD (3-11 years) using several approaches to enhance the validity of retrospective parent report. Both early development and outcome were examined in regression groups defined by 36 months age cut-off and two underlying empirical patterns based on type and onset age. Results over…

Raches, Christine M.; Hines, Elesia N.; Tomlin, Angela M. – ZERO TO THREE, 2019
Accurate diagnosis of Autism Spectrum Disorder (ASD) at an early age is increasingly sought so that the child and family can access early intervention and supports. However, not all children neatly fit into the diagnostic criteria for ASD, and additional assessment and supports are often required as providers continue to evaluate the possibility…

Cross-lagged panel analysis was used to examine associations between two joint engagement variables; higher order supported joint engagement and higher order supported joint engagement that co-occurs with caregiver's follow-in talk (higher order supported joint engagement + follow-in), and expressive and receptive vocabulary in a group of young…

Jin, Fufen; Schjølberg, Synnve; Wang, Mari Vaage; Eadie, Patricia; Nes, Ragnhild Bang; Røysamb, Espen; Tambs, Kristian – Journal of Speech, Language, and Hearing Research, 2020
Purpose: This article explored the predictive values of three main language delay (LD) trajectories (i.e., persistent, late onset, and transient) across 3-5 years on poor literacy at 8 years. Additionally, the effect of gender was assessed, using both gender-neutral and gender-specific thresholds. Method: The data comprised mother-reported…

Franchini, M.; Duku, E.; Armstrong, V.; Brian, J.; Bryson, S. E.; Garon, N.; Roberts, W.; Roncadin, C.; Zwaigenbaum, L.; Smith, I. M. – Journal of Autism and Developmental Disorders, 2018
Early communication impairment is among the most-reported first concerns in parents of young children with autism spectrum disorder (ASD). Using a parent-report questionnaire, we derived trajectory groups for early language and gesture acquisition in siblings at high risk for ASD and in children at low risk, during their first 2 years of life.…

West, Kelsey L.; Roemer, Emily J.; Northrup, Jessie B.; Iverson, Jana M. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Infants with autism spectrum disorder (ASD) produce fewer play actions and gestures than neurotypical infants (e.g., Mastrogiuseppe et al., 2015; Veness et al., 2012; Zwaigenbaum et al., 2005). The purpose of this study was to investigate whether different "types" of actions and gestures are more or less likely to develop…

Hartley, Calum; Trainer, Alice; Allen, Melissa L. – Autism: The International Journal of Research and Practice, 2019
Previous studies report that minimally verbal children with autism spectrum disorder show impaired picture comprehension when matched to typically developing controls on language comprehension. Here, we compare "both" picture comprehension and picture production abilities in linguistically delayed children with autism spectrum disorder…

Children's early language environments are related to later development. Little is known about this association in siblings of children with autism spectrum disorder (ASD), who often experience language delays or have ASD. Fifty-nine 9-month-old infants at high or low familial risk for ASD contributed full-day in-home language recordings.…

Iarocci, Grace; Hutchison, Sarah M.; O'Toole, Gillian – Journal of Autism and Developmental Disorders, 2017
Parents and professionals are concerned that second language exposure may delay communication in children with ASD. In this study 174 youth (6-16 years) with and without ASD, exposed to a second language, were compared on executive function (EF) and functional communication (FC) with their peers without exposure. There were no significant…

Chin, Iris; Goodwin, Matthew S.; Vosoughi, Soroush; Roy, Deb; Naigles, Letitia R. – Journal of Child Language, 2018
Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency,…

Brynskov, Cecilia; Eigsti, Inge-Marie; Jørgensen, Meta; Lemcke, Sanne; Bohn, Ocke-Schwen; Krøjgaard, Peter – Journal of Autism and Developmental Disorders, 2017
The current study examined delays in syntax and morphology, and vocabulary, in autism spectrum disorder (ASD). Children ages 4-6 years with ASD (n = 21) and typical development (n = 21), matched on nonverbal mental age, completed five language tasks. The ASD group had significant delays in both syntax and morphology, and vocabulary measures, with…
