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…

As an information-bearing auditory attribute of sound, pitch plays a crucial role in the perception of speech and music. Studies examining pitch processing in autism spectrum disorder have produced equivocal results. To understand this discrepancy from a mechanistic perspective, we used a novel data-driven method, the reverse-correlation paradigm,…

Fielding-Gebhardt, Heather; Bredin-Oja, Shelley L.; Warren, Steven F. – American Journal on Intellectual and Developmental Disabilities, 2021
The development of an expressive language score for people with autism based on the ADOS-2 was recently reported by Mazurek et al. (2019). The current study examined the construct validity of the ADOS-2 expressive language score (ELS) in a sample of adolescents with fragile X syndrome (n = 45, 10 girls), a neurodevelopmental disorder with high…

Bottema-Beutel, Kristen; Woynaroski, Tiffany; Louick, Rebecca; Stringer Keefe, Elizabeth; Watson, Linda R.; Yoder, Paul J. – Autism: The International Journal of Research and Practice, 2019
We examined differences between children with autism spectrum disorder and typically developing children over an 8-month period in: (a) longitudinal associations between expressive and receptive vocabulary and (b) the extent to which caregiver utterances provided within an "optimal" engagement state mediated the pathway from early…

Frazier, Thomas W.; Hauschild, Kathryn M.; Klingemier, Eric; Strauss, Mark S.; Hardan, Antonio Y.; Youngstrom, Eric A. – Journal of Intellectual & Developmental Disability, 2020
Background: Language assessment is a key element of evaluations of children and adolescents with neurodevelopmental disorders (NDDs). The present study examined the validity of a gaze-based receptive language index (RLI) in predicting language test results.Method: Participants included toddlers, pre-school, and school age children and adolescents…

Venker, Courtney E.; Ray-Subramanian, Corey E.; Bolt, Daniel M.; Weismer, Susan Ellis – Journal of Autism and Developmental Disorders, 2014
Relatively little is known about trajectories of autism severity using calibrated severity scores (CSS) from the Autism Diagnostic Observation Schedule, but characterizing these trajectories has important theoretical and clinical implications. This study examined CSS trajectories during early childhood. Participants were 129 children with autism…
