Blair, Bryan J.; Weiss, Julie S.; Ahearn, William H. – Education and Treatment of Children, 2018
Few published studies have systematically compared the efficacy of different prompt-fading methods in the training of complex response chains. The current study systematically compared a most-to-least physical prompt fading hierarchy with a most-to-least vocal prompt fading strategy in the training of four arbitrary Tinkertoy® construction tasks…

Soke, Gnakub Norbert; Rosenberg, Steven A.; Rosenberg, Cordelia Robinson; Vasa, Roma A.; Lee, Li-Ching; DiGuiseppi, Carolyn – Autism: The International Journal of Research and Practice, 2018
We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical…

The 16p11.2 duplication (BP4-BP5) is associated with Autism Spectrum Disorder (ASD), although significant heterogeneity exists. Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2…

The Study to Explore Early Development (SEED), a multisite investigation addressing knowledge gaps in autism phenotype and etiology, aims to: (1) characterize the autism behavioral phenotype and associated developmental, medical, and behavioral conditions and (2) investigate genetic and environmental risks with emphasis on immunologic, hormonal,…

Perovic, Alexandra; Modyanova, Nadya; Wexler, Ken – Language Acquisition: A Journal of Developmental Linguistics, 2013
This study investigates whether distinct neurodevelopmental disorders show distinct patterns of impairments in particular grammatical abilities and the relation of those grammatical patterns to general language delays and intellectual disabilities. We studied two disorders (autism and Williams syndrome [WS]) and two distinct properties (Principle…

Sumner, Emma; Leonard, Hayley C.; Hill, Elisabeth L. – Journal of Autism and Developmental Disorders, 2016
Motor and social difficulties are often found in children with an autism spectrum disorder (ASD) and with developmental coordination disorder (DCD), to varying degrees. This study investigated the extent of overlap of these problems in children aged 7-10 years who had a diagnosis of either ASD or DCD, compared to typically-developing controls.…

Van Laarhoven, Toni; Winiarski, Lauren; Blood, Erika; Chan, Jeffrey M. – Education and Training in Autism and Developmental Disabilities, 2012
A modified pre/posttest control group design was used to measure the effectiveness of video modeling on the maintenance of vocational tasks for six students with autism spectrum disorder and/or developmental disabilities. Each student was assigned two vocational tasks at their employment settings and their independence with each task was measured…

Donaldson, Jeanne M.; Vollmer, Timothy R. – Journal of Applied Behavior Analysis, 2011
A common recommendation for implementing time-out procedures is to include a release contingency such that the individual is not allowed to leave time-out until no problem behavior has occurred for a specific amount of time (e.g, 30 s). We compared a fixed duration time-out procedure to a release contingency time-out procedure with 4 young…

Ham, Heidi Stieglitz; Bartolo, Angela; Corley, Martin; Rajendran, Gnanathusharan; Szabo, Aniko; Swanson, Sara – Journal of Autism and Developmental Disorders, 2011
In this study, the relationship between gesture recognition and imitation was explored. Nineteen individuals with Autism Spectrum Disorder (ASD) were compared to a control group of 23 typically developing children on their ability to imitate and recognize three gesture types (transitive, intransitive, and pantomimes). The ASD group performed more…

Hart, Juliet E.; More, Cori M. – Education and Training in Autism and Developmental Disabilities, 2013
A rapidly growing developmental disability, autism spectrum disorder (ASD) affects 1 in 88 children. Although highly probable that both general and special educators will encounter ASD students, most teacher graduates receive minimal preparation in evidence-based practices for this population. The purpose of this study was to evaluate a…

Cotton, Sue M.; Richdale, Amanda L. – Research in Autism Spectrum Disorders, 2010
Sleep problems have often been reported in children with intellectual disabilities (ID). How anomalies in 24-h sleep patterns relate to behaviour difficulties in children with different types of ID remains to be elucidated. The purpose of this study was to assess 24-h sleep and behaviour patterns in children with a variety disorders including…

Santos, Andreia; Deruelle, Christine – Journal of Autism and Developmental Disorders, 2009
Research on theory of mind (TOM) has provided a major contribution to the understanding of developmental disorders characterized by atypical social behaviour. Yet, there is still little consensus relative to TOM abilities in Williams syndrome (WS). This study used visual and verbal tasks to investigate attribution of intentions in individuals with…

Smith, R. A.; Farnworth, H.; Wright, B.; Allgar, V. – Autism: The International Journal of Research and Practice, 2009
There is considerable controversy as to whether there is an association between bowel disorders and autism. Using a bowel symptom questionnaire we compared 51 children with autism spectrum disorder with control groups of 35 children from special school and 112 from mainstream school. There was a significant difference in the reporting of certain…

Ganz, Jennifer B.; Flores, Margaret M. – Journal of Autism and Developmental Disorders, 2008
The purpose of this study was to investigate the impact of visual strategies with preschool children with autism spectrum disorders (ASD) and their peers during play group sessions. A changing-criterion design was implemented with three preschool-aged children with ASD while they participated in play groups with four typically-developing peers.…

Deruelle, Christine; Rondan, Cecilie; Salle-Collemiche, Xavier; Bastard-Rosset, Delphine; Da Fonseca, David – Brain and Cognition, 2008
This study was aimed at investigating face categorization strategies in children with autistic spectrum disorders (ASD). Performance of 17 children with ASD was compared to that of 17 control children in a face-matching task, including hybrid faces (composed of two overlapping faces of different spatial bandwidths) and either low- or high-pass…
