This study examined the constructs underlying the Movement Assessment Battery for Children-2 (M-ABC-2), Bruninks-Oseretsky Test of Motor Proficiency (BOTMP) and Vineland Adaptive Behavior Scale-2 (VABS-2) using the framework of the International Classification of Functioning Disability and Health--Child Youth version (ICF-CY) and the diagnostic…

The study examined the effectiveness of Group Triple P, a Level 4 variant of the Triple P multilevel system of parenting support, with Chinese parents who had a preschool aged child with a developmental disability, using randomized controlled trial design. Participants (Intervention group: 42; Waitlist Control group: 39) completed measures on…

A dysfunction in predictive motor timing is put forward to underlie DCD-related motor problems. Predictive timing allows for the pre-selection of motor programmes (except "program" in computers) in order to decrease processing load and facilitate reactions. Using functional magnetic resonance imaging (fMRI), this study investigated the neural…

Historically people with significant disabilities were restricted to places such as adult activity centers, sheltered workshops, nursing homes, and institutions. Studies have shown the high school drop-out rate for this population is higher than those who are non-disabled. Policy makers concluded that these individuals needed to be better prepared…

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that…

Researchers have evaluated active support in agencies for persons with developmental disabilities to increase staff assistance and service user engagement. A systematic review identified two studies in which researchers reported three experimental evaluations of active support. Only one experiment showed a clear functional relationship between…

Parents are often the first to recognize early signs of developmental challenges, launching the family into an unanticipated journey that sometimes resolves quickly but sometimes not. Development depends on nurturing relationships that provide the necessary experiences to allow the child to develop. Equally important are the relationships that…

Background: Individuals with Prader-Willi syndrome (PWS) have been shown to demonstrate a particular cognitive deficit in attention switching and high levels of preference for routine and temper outbursts. This study assesses whether a specific pathway between a cognitive deficit and behaviour via environmental interaction can exist in individuals…

We sought to determine the effects of varying the perceptual demands of a suprapostural visual task on the postural activity of children with developmental coordination disorder (DCD), and typically developing children (TDC). Sixty-four (32 per group) children aged between 9 and 10 years participated. In a within-participants design, each child…

Purpose: To consider whether auditory processing disorder (APD) is truly a distinct clinical entity or whether auditory problems are more appropriately viewed as a processing deficit that may occur with various developmental disorders. Method: Theoretical and clinical factors associated with APD are critically evaluated. Results: There are…

We evaluated a video prompting procedure to teach adults with developmental disabilities to take a digital photograph and print it using a laptop computer and a printer. Participants were four men with developmental disabilities. Training was conducted at the participants' residential facility. During baseline, participants were told to take a…

Sleep disturbance is a common problem in children with developmental disabilities. Effective pharmacologic interventions are needed to ameliorate sleep problems that persist when behavior therapy alone is insufficient. The aim of the present study was to provide an overview of the quantity and quality of pharmacologic research targeting sleep in…

Although executive functions have been widely studied in individuals with autism spectrum disorders (ASD), there have been no direct empirical studies of executive abilities in savants with ASD. This study assessed three facets of executive ability (fluency, perseveration and monitoring) in savant artists with ASD, compared to non-talented adults…

In early training for children with autism spectrum disorders (ASDs), matching-to-sample (MTS) tasks are widely used to teach various language and cognitive skills. However, some problems in conducting MTS training for children with developmental disabilities are also recognized. In this study, we examined the effectiveness of stimulus pairing…

Everyone, including children with developmental disabilities, encounters stimuli they find aversive every day (e.g., the sound of a classmate tapping their pencil). These aversive stimuli may not be problematic for typically developing individuals, because they learn to behave in ways that allow them to escape or avoid this aversive stimulation.…
