Deserno, Marie K.; Fuhrmann, Delia; Begeer, Sander; Borsboom, Denny; Geurts, Hilde M.; Kievit, Rogier A. – Autism: The International Journal of Research and Practice, 2023
Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences…

Achermann, Sheila; Nyström, Pär; Bölte, Sven; Falck-Ytter, Terje – Autism: The International Journal of Research and Practice, 2020
Atypical motor development has frequently been reported in infants at elevated likelihood for autism spectrum disorder. However, no previous study has used detailed motion capture technology to compare infant siblings of children with autism spectrum disorder and infant siblings with no familial history of autism spectrum disorder. We investigated…

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10-19 years) and their first-born children (0-68 months).…

Duvall, Susanne W.; Huang-Storms, Lark; Presmanes Hill, Alison; Myers, Julianne; Fombonne, Eric – Journal of Autism and Developmental Disorders, 2020
Inconsistent findings regarding sex differences in cognition have been found in people with autism spectrum disorder (ASD). This study evaluated sex differences in cognitive-developmental functioning in a large clinical sample of young children diagnosed with ASD. The sample included children 18-68 months of age who received the Mullen Scales of…

Xin Zhang; Xue-Ke Song; Wing-Chee So – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children…

Guthrie, Whitney; Wetherby, Amy M.; Woods, Juliann; Schatschneider, Christopher; Holland, Renee D.; Morgan, Lindee; Lord, Catherine E. – Autism: The International Journal of Research and Practice, 2023
Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…

Mason-Apps, Emily; Stojanovik, Vesna; Houston-Price, Carmel; Seager, Emily; Buckley, Sue – Journal of Speech, Language, and Hearing Research, 2020
Purpose: The study explored longitudinally the course of vocabulary and general language development in a group of infants with Down syndrome (DS) compared to a group of typically developing (TD) infants matched on nonverbal mental ability (NVMA). Method: We compared the vocabulary and general language trajectories of the two groups in two ways:…

DeVeney, Shari L.; Kyvelidou, Anastasia; Mather, Paris – Autism & Developmental Language Impairments, 2021
Background and Aims: The purpose of this exploratory study was to expand existing literature on prelinguistic vocalizations by reporting results of the first home-based longitudinal study examining a wide variety of behaviors and characteristics, including early vocalizations, across infants at low and elevated risk of autism spectrum disorder…

There is a critical need for validated screening tools for autism spectrum disorder in very young children so families can access tailored intervention services as early as possible. Few screeners exist for children between the recommended screening ages of 18-24 months. This study examined the utility of a new autism-specific parent-report…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Purpose: Differences in communication development impact long-term outcomes of children with autism. Previous research has identified factors associated with communication in children with autism, but much of the variance in communication skill remains unexplained. It has been proposed that early differences in sensory responsiveness (i.e.,…

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…

Vivanti, Giacomo; Dissanayake, Cheryl; Duncan, Ed; Feary, Jessica; Capes, Kristy; Upson, Shannon; Bent, Catherine A.; Rogers, Sally J.; Hudry, Kristelle – Autism: The International Journal of Research and Practice, 2019
A major topic of debate is whether children with autism spectrum disorder should be educated in inclusive or specialized settings. We examined the feasibility and preliminary effectiveness of delivering the Group-Early Start Denver Model to children with autism spectrum disorder in inclusive versus specialized classrooms. We randomly assigned 44…

Bauminger-Zviely, Nirit; Shefer, Analia – Autism: The International Journal of Research and Practice, 2021
Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…

Children with autism spectrum disorder have a high risk of vision problems yet little is known about their vision care. This cross-sectional survey study, therefore, examined vision care among 351 children with autism spectrum disorder ages 6-17 years in the United States or Canada who were enrolled in the Autism Treatment Network Registry. Vision…
