Kraamwinkel, Elmien; Kritzinger, Alta – Communication Disorders Quarterly, 2022
Late language emergence (LLE) may result from genetic and environmental factors. Little is known about environmental factors in LLE in South Africa. The study describes the nature of differences in language functioning between toddlers with LLE and without LLE, and which factors were associated with LLE in a middle-income area in South Africa.…

Amin D. Lotfizadeh; Brendan Gard; Cynthia Rico; Alan Poling; Kristen R. Choi – Journal of Autism and Developmental Disorders, 2025
Behavior analysts frequently use the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess the language and social skills of children with autism in everyday practice and in research. Despite the widespread use of the VB-MAPP, its psychometric characteristics have not been extensively investigated. To provide information…

Zhou, Vanessa; Munson, Jeffrey A.; Greenson, Jessica; Hou, Yan; Rogers, Sally; Estes, Annette M. – Autism: The International Journal of Research and Practice, 2019
Little is known about outcomes of early intervention for children with autism spectrum disorder reared in bilingual homes. There are concerns that social communication deficits among children with autism spectrum disorder may reduce the developmental benefits of early intervention for children with autism spectrum disorder raised in bilingual…

Manwaring, Stacy S.; Mead, Danielle L.; Swineford, Lauren; Thurm, Audrey – International Journal of Language & Communication Disorders, 2017
Background: Nonverbal communication abilities, including gesture use, are impaired in autism spectrum disorder (ASD). However, little is known about how common gestures may influence or be influenced by other areas of development. Aims: To examine the relationships between gesture, fine motor and language in young children with ASD compared with a…

Plesa Skwerer, Daniela; Jordan, Samantha E.; Brukilacchio, Briana H.; Tager-Flusberg, Helen – Autism: The International Journal of Research and Practice, 2016
This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

Bennett, Teresa A.; Szatmari, Peter; Georgiades, Katholiki; Hanna, Steven; Janus, Magdelena; Georgiades, Stelios; Duku, Eric; Bryson, Susan; Fombonne, Eric; Smith, Isabel M.; Mirenda, Pat; Volden, Joanne; Waddell, Charlotte; Roberts, Wendy; Vaillancourt, Tracy; Zwaigenbaum, Lonnie; Elsabbagh, Mayada; Thompson, Ann – Journal of Child Psychology and Psychiatry, 2015
Background: Differences in how developmental pathways interact dynamically in children with autism spectrum disorder (ASD) likely contribute in important ways to phenotypic heterogeneity. This study aimed to model longitudinal reciprocal associations between social competence (SOC) and language (LANG) pathways in young children with ASD. Methods:…

Leaf, Justin B.; Dale, Stephanie; Kassardjian, Alyne; Tsuji, Kathleen H.; Taubman, Mitchell; McEachin, John J.; Leaf, Ronald B.; Oppenheim-Leaf, Misty L. – Education and Training in Autism and Developmental Disabilities, 2014
One of the basic principles of applied behavior analysis is that behavior change is largely due to that behavior being reinforced. Therefore the use of positive reinforcement is a key component of most behavioral programs for individuals diagnosed with autism. In this study we compared four different classes of reinforcers (i.e., food, praise,…

Lerna, Anna; Esposito, Dalila; Conson, Massimiliano; Massagli, Angelo – International Journal of Language & Communication Disorders, 2014
Background: The Picture Exchange Communication System (PECS) is a popular augmentative communication system frequently used with "nonverbal" children with autism. Several studies suggested that PECS could represent an effective tool for promoting improvement of several social-communicative skills. Only sparse evidence is instead…

Greenslade, Kathryn J.; Coggins, Truman E. – Journal of Autism and Developmental Disorders, 2016
This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7 years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

Park, Carlie J.; Yelland, Gregory W.; Taffe, John R.; Gray, Kylie M. – Journal of Autism and Developmental Disorders, 2012
This study investigated the relationship between structural language skills, and communication skills, adaptive behavior, and emotional and behavior problems in pre-school children with autism. Participants were aged 3-5 years with autism (n = 27), and two comparison groups of children with developmental delay without autism (n = 12) and typically…

Hardan, Antonio Y.; Gengoux, Grace W.; Berquist, Kari L.; Libove, Robin A.; Ardel, Christina M.; Phillips, Jennifer; Frazier, Thomas W.; Minjarez, Mendy B. – Journal of Child Psychology and Psychiatry, 2015
Background: With rates of autism diagnosis continuing to rise, there is an urgent need for effective and efficient service delivery models. Pivotal Response Treatment (PRT) is considered an established treatment for autism spectrum disorder (ASD); however, there have been few well-controlled studies with adequate sample size. The aim of this study…

Tonge, Bruce; Brereton, Avril; Kiomall, Melissa; Mackinnon, Andrew; Rinehart, Nicole J. – Autism: The International Journal of Research and Practice, 2014
Aim: To determine the effect of parent education on adaptive behaviour, autism symptoms and cognitive/language skills of young children with autistic disorder. Method: A randomised group comparison design involving a parent education and counselling intervention and a parent education and behaviour management intervention to control for parent…

Martin, Jolene Hyppa; Reichle, Joe; Dimian, Adele; Chen, Mo – Language, Speech, and Hearing Services in Schools, 2013
Purpose: Vocal, gestural, and graphic communication modes were implemented concurrently with a toddler with Angelman syndrome to identify the most efficiently learned communication mode to emphasize in an initial augmentative communication system. Method: Symbols representing preferred objects were introduced in vocal, gestural, and graphic…

Bailey, Benjamin; Arciuli, Joanne; Stancliffe, Roger J. – Scientific Studies of Reading, 2017
This study explored the effects of an evidence-based literacy program, ABRACADABRA, on the spelling abilities of children with autism spectrum disorder (ASD). Twenty children with ASD aged 5-11 years were assigned to matched instruction and waitlist control groups. Children in the instruction group received 26 hrs of individualized, home-based…

Sainato, Diane M.; Morrison, Rebecca S.; Jung, Sunhwa; Axe, Judah; Nixon, Patricia A. – Journal of Early Intervention, 2015
To date, reports of empirically validated comprehensive intervention programs for children with autism spectrum disorder (ASD) have been limited to preschool-age children. We examined the effects of a model inclusive kindergarten program for children with ASD. Forty-one children received instruction in an inclusive kindergarten program with their…
