Resting Frontal Gamma Power Is Associated with Both Expressive Language and Non-Verbal Cognitive Abilities in Young Autistic Children
Peer reviewed Peer reviewed
Direct linkDirect link
Cora E. Mukerji; John S. Wilson III; Carol L. Wilkinson; Manon A. Krol; Charles A. Nelson; Helen Tager-Flusberg – Journal of Autism and Developmental Disorders, 2025
Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Golden; Claire Daly; Sophia Kaiser; Nisha Mailapur; Sweeya Raj; Pooja Santapuram; Evan Suzman; Ashley E. Augustine; Aine Muhumuza; Carissa J. Cascio; Kathryn L. Williams; Anne V. 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…

Parsons, Dave; Cordier, Reinie; Lee, Hoe; Falkmer, Torbjorn; Vaz, Sharmila – Journal of Autism and Developmental Disorders, 2019
This exploratory randomised controlled trial tested the effectiveness of a tablet-based information communication technology early intervention application to augment existing therapy with the aim of improving visual motor, imitation, language and social skills in young children with ASD who reside in regional areas. Fifty-nine participants were…

Trajectories of Autism Severity in Early Childhood
Peer reviewed Peer reviewed
Direct linkDirect link
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…

Receptive and Expressive Language as Predictors of Restricted and Repetitive Behaviors in Young Children with Autism Spectrum Disorders
Peer reviewed Peer reviewed
Direct linkDirect link
Ray-Subramanian, Corey E.; Ellis Weismer, Susan – Journal of Autism and Developmental Disorders, 2012
This study examined whether language skills and nonverbal cognitive skills were associated with clinician-observed restricted and repetitive behaviors (RRBs) in a sample of 115 children with autism spectrum disorders (ASD) at ages 2 and 3. By age 3, RRBs were significantly negatively correlated with receptive and expressive language, as well as…

Developmental Profiles of Infants and Toddlers with Autism Spectrum Disorders Identified Prospectively in a Community-Based Setting
Peer reviewed Peer reviewed

Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2012
This prospective, longitudinal, study charted the developmental profiles of young children with Autism Spectrum Disorders (ASD) identified through routine developmental surveillance. 109 children with Autistic Disorder (AD), "broader" ASD, and developmental and/or language delays (DD/LD) were assessed using the Mullen Scales of Early Learning…

Cognitive Ability Is Associated with Different Outcome Trajectories in Autism Spectrum Disorders
Peer reviewed Peer reviewed

Ben-Itzchak, Esther; Watson, Linda R.; Zachor, Ditza A. – Journal of Autism and Developmental Disorders, 2014
Variability in clinical expression and in intervention outcome has been described in autism spectrum disorder (ASD). The study examined progress after 1 and 2 years of intervention and compared the impact of baseline cognitive ability on outcome trajectories in 46 children (m = 25.5 months) with ASD. The entire group showed a gradual decrease in…

Imitation Assessment and Its Utility to the Diagnosis of Autism: Evidence from Consecutive Clinical Preschool Referrals for Suspected Autism
Peer reviewed Peer reviewed
Direct linkDirect link
Vanvuchelen, Marleen; Roeyers, Herbert; De Weerdt, Willy – Journal of Autism and Developmental Disorders, 2011
The present study sought to examine imitation difficulties as a risk factor for autism. Imitation aptitude was examined in 86 preschoolers suspected of autism (1.9-4.5 years) using the Preschool Imitation and Praxis Scale (PIPS). Differences between imitation, language, motor age-equivalents and nonverbal mental age were used to predict the…

Luyster, Rhiannon J.; Kadlec, Mary Beth; Carter, Alice; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2008
One of the primary diagnostic criteria for the diagnosis of autism spectrum disorders (ASD) is the presence of a language delay or impairment. Children with ASD are now being identified at significantly younger ages, and prior research has consistently found that early language skills in this population are heterogeneous and an important predictor…

Symbolic Play in Children with Autism Spectrum Disorder
Peer reviewed Peer reviewed

Stanley, Gillian C.; Konstantareas, M. Mary – Journal of Autism and Developmental Disorders, 2007
The relationship between symbolic play and other domains, such as degree of autistic symptomatology, nonverbal cognitive ability, receptive language, expressive language, and social development, was investigated. The assessment files of 101 children with Autism Spectrum Disorder were studied. Nonverbal cognitive ability and expressive language…

Toth, Karen; Dawson, Geraldine; Meltzoff, Andrew N.; Greenson, Jessica; Fein, Deborah – Journal of Autism and Developmental Disorders, 2007
Studies are needed to better understand the broad autism phenotype in young siblings of children with autism. Cognitive, adaptive, social, imitation, play, and language abilities were examined in 42 non-autistic siblings and 20 toddlers with no family history of autism, ages 18-27 months. Siblings, as a group, were below average in expressive…

Sequential and Simultaneous Processing Abilities of High-Functioning Autistic and Language-Impaired Children.
Peer reviewed Peer reviewed
Allen, Mark H.; And Others – Journal of Autism and Developmental Disorders, 1991
This study found that a group of 20 children (ages 6-12) with autism and a group of 20 children with developmental receptive language disorder both manifested a relative sequential processing deficit. The groups did not differ significantly on overall sequential and simultaneous processing capabilities relative to their degree of language…

Thurm, Audrey; Lord, Catherine; Lee, Li-Ching; Newschaffer, Craig – Journal of Autism and Developmental Disorders, 2007
In 118 children followed from age 2 to 5 (59 with autism, 24 with PDD-NOS and 35 with non-spectrum developmental disabilities), age 2 and age 3 scores of non-verbal ability, receptive communication, expressive communication and socialization were compared as predictors of receptive and expressive language at age 5. Non-verbal cognitive ability at…
