People with developmental disabilities sleep less and experience higher incidence of clinical sleep disorders than the general population. Exploring the neurophysiology linking sleep with daytime performance in patients with developmental disabilities is now possible using minimally sufficient sleep and sleep-sensitive behavioral assays. Although…

There is mounting evidence that employer-provided health insurance is an important factor in recruiting and retaining a competent and motivated direct support workforce within health and human services occupations. A review of the literature in this area, including new information related to the developmental disabilities field, is presented to…

Stimulus preference assessments for individuals with developmental disabilities typically involve offering choices among stimuli and providing immediate access to the chosen stimuli. Several researchers have explored the utility of presenting choices verbally, thereby obviating the need to present the choices in tangible form and deliver access to…

In 2 experiments, each involving different mathematical operations, we compared 2 training procedures for teaching component math skills in terms of their effects on the learning and long-term maintenance of composite skill. The dependent variables were learn units to composite task mastery and performance on the composite task 2 months later. The…

The aim was to explore the comorbidity between Angelman syndrome and autism spectrum disorders (ASDs). Identification of autism in children with Angelman syndrome presents a diagnostic challenge. In the present study, 16 children with Angelman syndrome, all with a 15q11-13 deletion, were examined for ASDs. Thirteen children with Angelman syndrome…

The origin and developmental course of stereotypic and self-injurious behaviour among individuals with developmental disabilities such as intellectual disability (ID) or pervasive development disorders such as autism is not well understood. Twelve studies designed to document the prevalence, nature, or development of stereotypic and/or…

There is an increasing awareness that the astrocytes in the immature periventricular white matter are vulnerable to ischemia and respond to inflammation. Here we provide a synopsis of the articles that have evaluated the causes and consequences of developmental brain injuries to white matter astrocytes as well as the consequences of several…

Over the past decade, cognitive approaches with children with developmental coordination disorder (DCD) have been investigated. Although studies have focused on intervention outcomes, few have documented the components of the approach that support the enhancement of children's performance. This study used systematic observation of videotaped…

Profiles of verbal learning and memory performance were compared for typically developing children and for four developmental disorders characterized by different patterns of language functioning: specific language impairment, early focal brain damage, Williams Syndrome, and Down Syndrome. A list-learning task was used that allowed a detailed…

The Individuals With Disabilities Education Act (IDEA) Amendments of 1997 mandate the use of functional behavioral assessment (FBA) and positive behavioral supports and interventions for students with disabilities. Although much progress has been made in our understanding of functional analysis over the past 15 years, the extent to which these…

Background: Prior studies have showed that presentation methods could affect the accuracy of a choice assessment. Methods: In the current study, high- and low- preferred work tasks were identified in nine adults with developmental disabilities. Both tasks were then introduced in pairs within a choice assessment using the actual tasks, pictures of…

Expanding on Reese "et al." [2003], functional behavioral assessment interviews [O'Neill "et al.", 1997] concerning disruptive behavior were conducted with parents of 23 children with autism (6 females, 17 males, chronological ages [CA] 24-60 months) and 23 controls without autism pair-matched for CA, developmental age and sex. All children…

Global information processing and perception of facial age and emotional expression was studied in children with autism, language disorders, mental retardation, and a clinical control group. Children were given a global-local task and asked to recognize age and emotion in human and canine faces. Children with autism made fewer global responses and…

Recent legislation, especially the Americans with Disabilities Act in 1990, generated the closure of institutions for people with disabilities and inclusion into community residences and employment. It has been well documented that individuals with developmental disabilities often experience difficulties with employment including both obtaining…

Over the past decade, there has been increased interest in crimes against people with developmental disabilities (PWDD). While national and international information has been available on homicides of people in general, little attention has been given to homicides of PWDD specifically. This paper provides a preliminary description of homicides as…
