Tsai, Luke Y.; Ghaziuddin, Mohammad – Journal of Autism and Developmental Disorders, 2014
The fifth edition of the diagnostic and statistical manual of mental disorders (DSM-5) (APA in diagnostic and statistical manual of mental disorders, Author, Washington, 2013) has decided to merge the subtypes of pervasive developmental disorders into a single category of autism spectrum disorder (ASD) on the assumption that they cannot be…

We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Sah, Wen-hui – First Language, 2018
This study investigates the referential choice of Mandarin-speaking children with autism spectrum disorder (ASD). The data consist of narratives from 16 children with ASD and 16 typically-developing (TD) children. The narratives were elicited using the wordless picture book "Frog, where are you?" Participants' referential expressions…

Problem-Solving Styles in Autism Spectrum Disorder and the Development of Higher Cognitive Functions
Constable, Paul A.; Ring, Melanie; Gaigg, Sebastian B.; Bowler, Dermot M. – Autism: The International Journal of Research and Practice, 2018
The Vygotsky Blocks Test assesses problem-solving styles within a theoretical framework for the development of higher mental processes devised by Vygotsky. Because both the theory and the associated test situate cognitive development within the child's social and linguistic context, they address conceptual issues around the developmental relation…

M. – Autism: The International Journal of Research and Practice, 2016
Growing awareness of autism spectrum disorders has increased the demand for diagnostic services in adulthood. High rates of mental health problems have been reported in young people and adults with autism spectrum disorder. However, sampling and methodological issues mean prevalence estimates and conclusions about specificity in psychiatric…

Sani Bozkurt, Sunagul; Vuran, Sezgin – Educational Sciences: Theory and Practice, 2014
Social stories play a significant part in the teaching skills and behaviors to children with ASD who lack social skills. The purpose of this study is to analyze studies in which social stories were used for teaching social skills to individuals with Autism Spectrum Disorders (ASD). The present study includes a descriptive review and meta-analysis…

Kiani, R.; Tyrer, F.; Hodgson, A.; Berkin, N.; Bhaumik, S. – Journal of Intellectual Disability Research, 2013
Background: In the general population there are statistically significant urban-rural differences in the rate of common mental disorders. In people with intellectual disability (ID) no study has attempted to address this issue. Aims: To compare the prevalence of mental illness, autism spectrum disorder (ASD) and behaviour disorder in people with…

Baum, Katherine T.; Shear, Paula K.; Howe, Steven R.; Bishop, Somer L. – Autism: The International Journal of Research and Practice, 2015
In autism spectrum disorders, results of cognitive testing inform clinical care, theories of neurodevelopment, and research design. The Wechsler Intelligence Scale for Children and the Stanford-Binet are commonly used in autism spectrum disorder evaluations and scores from these tests have been shown to be highly correlated in typically developing…

Lecavalier, Luc; Gadow, Kenneth D.; DeVincent, Carla J.; Houts, Carrie; Edwards, Michael C. – Journal of Child Psychology and Psychiatry, 2009
Background: Empirical studies of the structure of autism symptoms have challenged the three-domain model of impairment currently characterizing pervasive developmental disorders (PDD). The objective of this study was to assess the internal validity of the DSM as a conceptual model for describing PDD, while paying particular attention to certain…

Sevin, Jay A.; And Others – Journal of Autism and Developmental Disorders, 1995
A cluster analytic study was conducted to derive behaviorally homogeneous subtypes of pervasive developmental disorders (PDD) based on a range of behavioral symptoms that characterize autism. Analysis of data on 34 children with PDD, 27 of whom met criteria for autism, indicated 4 distinct groups differing on independent measures of social,…
