Nordahl-Hansen, Anders; Donolato, Enrica; Lervåg, Arne; Norbury, Courtenay Frazier; Melby-Lervåg, Monica – Campbell Systematic Reviews, 2019
This protocol presents the plan for a systematic review that investigates the effect of oral language interventions for children with intellectual disability (ID), language disorder (LD), autism spectrum disorder (ASD), Down syndrome (DS), Williams syndrome (WS), and fragile X syndrome (FXS). Language development is a highly frequent area of…

Rubenstein, Eric; Wiggins, Lisa D.; Schieve, Laura A.; Bradley, Chyrise; DiGuiseppi, Carolyn; Moody, Eric; Pandey, Juhi; Pretzel, Rebecca Edmondson; Howard, Annie Green; Olshan, Andrew F.; Pence, Brian W.; Daniels, Julie – Autism: The International Journal of Research and Practice, 2019
The autism spectrum disorder phenotype varies by social and communication ability and co-occurring developmental, behavioral, and medical conditions. Etiology is also diverse, with myriad potential genetic origins and environmental risk factors. Examining the influence of parental broader autism phenotype--a set of sub-clinical characteristics of…

Swanson, Meghan R.; Shen, Mark D.; Wolff, Jason J.; Boyd, Brian; Clements, Mark; Rehg, James; Elison, Jed T.; Paterson, Sarah; Parish-Morris, Julia; Chappell, J. Chad; Hazlett, Heather C.; Emerson, Robert W.; Botteron, Kelly; Pandey, Juhi; Schultz, Robert T.; Dager, Stephen R.; Zwaigenbaum, Lonnie; Estes, Annette M.; Piven, Joseph – Child Development, 2018
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.…

Edwards, Laura A.; Wagner, Jennifer B.; Tager-Flusberg, Helen; Nelson, Charles A. – Journal of Autism and Developmental Disorders, 2017
In this study, we investigated neural precursors of language acquisition as potential endophenotypes of autism spectrum disorder (ASD) in 3-month-old infants at high and low familial ASD risk. Infants were imaged using functional near-infrared spectroscopy while they listened to auditory stimuli containing syllable repetitions; their neural…

Lin, Ping-I; Chien, Yi-Ling; Wu, Yu-Yu; Chen, Chia-Hsiang; Gau, Susan Shur-Fen; Huang, Yu-Shu; Liu, Shih-Kai; Tsai, Wen-Che; Chiu, Yen-Nan – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Previous evidence suggests that language function is modulated by genetic variants on chromosome 7q31-36. However, it is unclear whether this region harbors loci that contribute to speech delay in autism. We previously reported that the WNT2 gene located on 7q31 was associated with the risk of autism. Additionally, two other genes on 7q31-36,…

Zampini, Laura; D'Odorico, Laura; Zanchi, Paola; Zollino, Marcella; Neri, Giovanni – Clinical Linguistics & Phonetics, 2012
The present study focussed on a specific type of rare genetic condition: chromosome 14 deletions. Children with this genetic condition often show developmental delays and brain and neurological problems, although the type and severity of symptoms varies depending on the size and location of the deleted genetic material. The specific aim of the…

Hahn, Laura J.; Brady, Nancy C.; Fleming, Kandace; Warren, Steven F. – Journal of Speech, Language, and Hearing Research, 2016
Purpose: In this study, we examine joint engagement (JE) in young children with fragile X syndrome (FXS) and its relationship to language abilities and autism spectrum disorder symptomatology at 24 to 36 months (toddler period) and 59 to 68 months (child period). Method: Participants were 28 children with FXS (24 boys, four girls) and their…

Van Den Heuvel, Ellen; Botting, Nicola; Boudewijns, Inge; Manders, Eric; Swillen, Ann; Zink, Inge – First Language, 2017
This study investigated three conversational subskills in children with 22q11.2 deletion syndrome (22q11.2DS, n = 8, ages 7-13) and Williams syndrome (WS, n = 8, ages 6-12). The researchers re-evaluated these subskills after 18 to 24 months and compared them to those of peers with idiopathic intellectual disability (IID) and IID and comorbid…

Naigles, Letitia R., Ed. – APA Books, 2017
In recent decades, a growing number of children have been diagnosed with autism spectrum disorder (ASD), a condition characterized by social interaction deficits and language impairment. Yet the precise nature of the disorder's impact on language development is not well understood, in part because of the language variability among children across…

Interagency Autism Coordinating Committee, 2020
Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field. The "2019 IACC Summary of Advances" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles nominated by the…

Leezenbaum, Nina B.; Campbell, Susan B.; Butler, Derrecka; Iverson, Jana M. – Autism: The International Journal of Research and Practice, 2014
This study investigates mothers' responses to infant communication among infants at heightened genetic risk (high risk) of autism spectrum disorder compared to infants with no such risk (low risk). A total of 26 infants, 12 of whom had an older sibling with autism spectrum disorder, were observed during naturalistic in-home interaction and…

Gliga, Teodora; Elsabbagh, Mayada; Hudry, Kristelle; Charman, Tony; Johnson, Mark H. – Child Development, 2012
This study investigated gaze-following abilities as a prerequisite for word learning, in a population expected to manifest a wide range of social and communicative skills--children with a family history of autism. Fifty-three 3-year-olds with or without a family history of autism took part in a televised word-learning task. Using an eye-tracker to…

McDuffie, Andrea; Kover, Sara T.; Hagerman, Randi; Abbeduto, Leonard – Journal of Autism and Developmental Disorders, 2013
Fast-mapping paradigms have not been used previously to examine the process of word learning in boys with fragile X syndrome (FXS), who are likely to have intellectual impairment, language delays, and symptoms of autism. In this study, a fast-mapping task was used to investigate associative word learning in 4- to 10-year-old boys with FXS relative…

Chaidez, Virginia; Hansen, Robin L.; Hertz-Picciotto, Irva – Autism: The International Journal of Research and Practice, 2012
Objectives: To compare differences in autism between Hispanic and non-Hispanics. We also examined the relationship between multiple language exposure and language function and scores of children. Methods: The Childhood Autism Risks from Genetics and the Environment (CHARGE) study is an ongoing population-based case-control study with children…

Kover, Sara T. – ProQuest LLC, 2012
Fragile X syndrome is the leading inherited cause of intellectual disability. Most boys with fragile X syndrome have impaired cognition and language deficits, with significant within-syndrome variability. Syntax may be especially delayed relative to nonverbal cognition; however, little is known about the specificity of delay, the sources of that…
