Direct linkPrescott, Kathryn E.; Ellis Weismer, Susan – Journal of Autism and Developmental Disorders, 2022
This study investigated receptive and expressive language outcomes in children with autism spectrum disorder (ASD) with and without a history of language/communication regression, employing three progressively less stringent definitions of regression. Data were derived from a large, longitudinal sample of children with ASD in which regression was…

Maltman, Nell; Friedman, Laura; Lorang, Emily; Sterling, Audra – Journal of Autism and Developmental Disorders, 2022
Autism spectrum disorder (ASD) and fragile X syndrome (FXS) are neurodevelopmental disorders with overlapping pragmatic language impairments. Prior work suggests pragmatic language differences may run in families. This study examined specific pragmatic difficulties (i.e., linguistic mazes and perseverations) in boys (9-18 years) with idiopathic…

Moore, Heather L.; Rogan, Leanne; Taylor, Lauren J.; Charman, Tony; Le Couteur, Ann; Green, Jonathan; Grahame, Victoria – Journal of Autism and Developmental Disorders, 2022
A wealth of parent-report research shows adaptive functioning difficulties in autistic children, with parent-report influenced by a number of child factors. Adaptive functioning in autistic children is known to vary across settings; however, no research has yet explored factors influencing education professional-report. This study investigated the…

Silva, Daniela P.; Fiske, Kate E. – Journal of Behavioral Education, 2021
Researchers widely assert that requiring eye contact from students with autism spectrum disorder (ASD) before instruction is highly important to the outcome of teaching (Greer and Ross in Verbal behavior analysis, Pearson Education, New York, 2008; Lovaas in J Consult Clin Psychol 55(1):3-9, 1977. https://bibliotheek.ehb.be:2102/10.1037/0022-006x.55.1.3).…

Barokova, Mihaela; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2020
The role of language in autism spectrum disorder (ASD), more specifically, its function in social communication and strong predictive power on future outcomes, warrants language assessments that have good psychometric properties that capture the heterogeneity of language ability found among diagnosed individuals. Given the rapid growth in…

Looking to the mouth of a talker early in life predicts expressive communication. We hypothesized that looking at a talker's mouth may signal that infants are ready for increased supported joint engagement and that it subsequently facilitates prelinguistic vocal development and translates to broader gains in expressive communication. We tested…

Cook, Alexandria; Quinn, Emily D.; Rowland, Charity – American Journal on Intellectual and Developmental Disabilities, 2021
Individuals with a comorbid diagnosis of Down syndrome (DS) and autism spectrum disorder (ASD) have been found to exhibit greater deficits in expressive communication than individuals with DS only. We hypothesized that individuals with a comorbid diagnosis (n = 430) would have significantly lower Communication Matrix scores and specifically social…

McDaniel, Jena; Yoder, Paul; Estes, Annette; Rogers, Sally J. – American Journal on Intellectual and Developmental Disabilities, 2021
The Early Communication Indicator (ECI) was designed to measure expressive communication progress in young children. We evaluated using the 6-min ECI procedure for a new purpose--a sampling context for stable measures of vocal development of young children with autism spectrum disorder (ASD). We evaluated how many ECI sessions were required to…

Sengül, Yasemin; Ökcün-Akçamus, Meral Çilem; Bakkaloglu, Hatice – European Journal of Special Needs Education, 2021
The aim of this study was to examine classification accuracy for the expressive language skills of children with autism spectrum disorder (ASD) in terms of object play and imitation scores. A total of 61 children with ASD, who were 2.0-5.11 years old, were included in the study. In order to collect data play and imitation assessment tasks which…

McFayden, Tyler C.; Fok, Megan; Ollendick, Thomas H. – Journal of Autism and Developmental Disorders, 2022
The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in…

McDaniel, Jena; Yoder, Paul; Estes, Annette; Rogers, Sally J. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: This study was designed to test the incremental validity of more expensive vocal development variables relative to less expensive variables for predicting later expressive language in children with autism spectrum disorder (ASD). We devote particular attention to the added value of coding the quality of vocalizations over the quantity of…

Our aim was to explore insights from clinical practice that may inform efforts to understand and account for factors that predict spoken language outcomes for children with Autism Spectrum Disorder who use minimal verbal language. We used a qualitative design involving three focus groups with 14 speech pathologists to explore their views and…

Aljohani, Wafa A.; Javed, Asim; Ferguson, Julia L.; Cihon, Joseph H.; Milne, Christine M.; Leaf, Justin B. – Focus on Autism and Other Developmental Disabilities, 2022
This study compared simultaneous prompting with an error correction procedure for teaching three children diagnosed with autism spectrum disorder expressive labels. Using a parallel treatment design nested within a multiple probe design, the researchers taught each participant how to expressively label pictures of sports teams or cartoon…

Koegel, Lynn Kern; Bryan, Katherine M.; Su, Pumpki L.; Vaidya, Mohini; Camarata, Stephen – Journal of Autism and Developmental Disorders, 2020
This systematic review examined definitions of "nonverbal" or "minimally verbal" and assessment measures used to evaluate communication in intervention studies focusing on improving expressive verbal communication in children with autism spectrum disorder (ASD). We reviewed sample size, number of participants, participant age,…

Dimitrova, Nevena; Mohr, Christine; Özçaliskan, Seyda; Adamson, Lauren B. – Journal of Autism and Developmental Disorders, 2020
Children with autism spectrum disorder (ASD) produce fewer deictic gestures, accompanied by delays/deviations in speech development, compared to typically-developing (TD) children. We ask whether children with ASD--like TD children--show right-hand preference in gesturing and whether right-handed gestures predict their vocabulary size in speech.…
