Structural variation of the human genome sequence is the insertion, deletion, or rearrangement of stretches of DNA sequence sized from around 1,000 to millions of base pairs. Over the past few years, structural variation has been shown to be far more common in human genomes than previously thought. Very little is currently known about the effects…

The present study examined the link between brain hemisphericity and dyslexia in secondary school students, using the Preference Test (PT), a widely used self-report index of preferred hemisphere thinking styles. The hypothesis was that differences would be revealed between the dyslexic group and their peers in hemispheric preference. A total of…

Individuals with attention deficit hyperactive disorder (ADHD) often have coexisting developmental coordination disorder (DCD). The positive therapeutic effect of methylphenidate on ADHD symptoms is well documented, but its effects on motor coordination are less studied. We assessed the influence of methylphenidate on motor performance in children…

Some students who have developmental disabilities avoid settings and activities that can improve their learning and quality of life. This two-phase study concerned an adolescent boy with autism who avoided the gross-motor exercise room, gymnasium, and music room at his school; he demonstrated distress, agitation, and problem behaviors when…

This study investigated the efficacy of a writing (ANSWER) strategy to improve the essay test responses of students who were enrolled in a campus-based, postsecondary education program for individuals with developmental disabilities. Random assignment to treatment or control groups and a pre- and posttest design were employed. Students used the…

Although there is a variety of literature that offers adaptations and teaching suggestions for paddling with individuals who have physical disabilities, only a few address the needs of individuals with developmental disabilities (Gullion, 2009; Zeller, 2009). Developmental disabilities refer to a diverse group of severe chronic conditions that are…

Excessive grip force (GF) is often found in children with developmental coordination disorder (DCD). However, their GF control may vary when task constraints are imposed upon their motor performance. This study aimed to investigate how their GF control changes in response to task demands, and to examine their tactile sensitivity. Twenty-one…

The present study examined daytime sleep patterns in 3 groups of preschool-aged children: children with autism, children with developmental delay, and children who were developing typically. Sleep was assessed in 194 children via actigraphy and parent-report sleep diaries for 7 consecutive days on 3 separate occasions over 6 months. Children with…

Our purpose in this study is to offer a more comprehensive understanding of how students with intellectual and developmental disabilities attending postsecondary education programs are prepared for competitive employment. Data collected through a national survey indicate that the vocational-related support services offered frequently by…

Background: Statements or commitments making use of numbers have an important place in government policy. They appear at all stages of the policy process: campaigning, formulation, monitoring and evaluation. Many types of sources are involved including research studies, national survey information, routine operational data collections and special…

Depression is a serious disorder with severe and far-reaching consequences. Two decades of observational research have shown robust associations between maternal depression and adverse consequences on offspring (S. Campbell et al., 2004; S. Campbell, P. Matestic, C. von Stauffenberg, R. Mohan, & T. Kirchner, 2007; S. Campbell, A. Morgan-Lopez,…

Background: Language development has been characterised by significant individual stability from school entry. However, the extent to which trajectories of language growth vary in children with language disorder as a function of co-occurring developmental challenges is a question of theoretical import, with implications for service provision.…

The aim of this study is to describe the mathematical thinking process of autistic students in terms of gesture, using a qualitative approach. Data collecting is conducted by using 3 (three) audio-visual cameras. During the learning process, both teacher and students' activity are recorded using handy cam and digital camera (full HD capacity).…

This study investigated the psychometric properties of the Child and Family Quality of Life scale, a measure of psychosocial quality of life in those with autism and related developmental disorders. Parents of 212 children suspected of autism spectrum disorder completed the Child and Family Quality of Life prior to a diagnostic evaluation. Results…

This article discusses the use of assistive technology (AT) in the context of three current international trends in the field of intellectual disability (ID) that are significantly impacting the delivery of services and supports to persons with ID: the provision of systems of supports based on the individual's assessed support needs, the increased…
