Purpose: The present article illustrates how the National Household Education Surveys (NHES; U.S. Department of Education, 2009) database might be used to address questions of relevance to researchers who are concerned with literacy development among young children. Following a general description of the NHES database, a study is provided that…

The purpose of this study was to compare cardiopulmonary fitness and endurance in 9-11-year-old children with DCD against a group of typically developing children in Taiwan. The Movement ABC test was used to evaluate the motor abilities of children. Forty-one participants (20 children with DCD and 21 children without DCD) were recruited for this…

The use of weighted vests for children with autism spectrum disorders and developmental disabilities is a common practice as part of sensory integration therapy programs. The purpose of the current investigation was to extend the research on the use of weighted vests for children with autism and developmental delays in a methodologically rigorous…

In order to maximize the learning of skills, it is crucial that the most powerful reinforcement be used. Research describes several different methods of reinforcement preference assessments, including forced choice, free-operant, and multiple stimulus array procedures. Researchers have also tested many variables to determine their potential impact…

Assessment systems are needed that are sensitive to employees' work performance as well as their need for support, while incorporating the input from both employees and their supervisors. This study examined the correspondence of one such evaluation system, the Job Observation and Behavior Scale (JOBS) and the JOBS: Opportunity for…

Our goal was to examine the feasibility of applying therapeutic robotics to children and adults with severe to moderate impairment due to cerebral palsy (CP). Pilot results demonstrated significant gains for both groups. These results suggest that robot-mediated therapy may be an effective tool to ameliorate the debilitating effects of CP and…

Descriptive observations were conducted to record problem behavior displayed by participants and to record antecedents and consequences delivered by caregivers. Next, functional analyses were conducted to identify reinforcers for problem behavior. Then, using data from the descriptive observations, lag-sequential analyses were conducted to examine…

Early identification of intellectual and developmental disabilities in persons in the criminal justice system is essential to protect their rights during arrest and trial, ensure safety when incarcerated, and maximize the opportunities to receive services while incarcerated and postrelease. Using telephone interviews of jail administrators (N =…

Williams Syndrome (WS) is a rare neurodevelopmental disorder, which stems from a genetic deletion on chromosome 7 and causes a profound weakness in visuospatial cognition. Our current study explores how orientation perception may contribute to the visuospatial deficits in WS. In Experiment 1, we found that WS individuals and normal 3-4 year olds…

If the members of a functional response class occur in a predictable order, a response-class hierarchy is said to exist. Although this topic has received some attention in the applied literature, it remains relatively understudied. The purpose of the current investigation was to develop an analogue model of a response-class hierarchy. Children…

Problems faced by the developmental disability service system in recruiting and retaining direct support staff are exacerbated by demands from competing service industries, including long term supports for the increasing aging population in the United States. Many factors account for high turnover and vacancy rates in the community service system,…

Problem behaviors present a significant challenge for individuals with developmental disabilities and their caregivers. Interventions based on behavioral principles are effective in treating problem behaviors; however, some caregivers have difficulty adhering to treatment recommendations. Treatment adherence may be affected by the technical nature…

According to a recent theory of dyslexia, the "perceptual anchor theory," children with dyslexia show deficits in classic auditory and phonological tasks not because they have auditory or phonological impairments but because they are unable to form a "perceptual anchor" in tasks that rely on a small set of repeated stimuli. The theory makes the…

We measured small intestinal permeability using a lactulose:mannitol sugar permeability test in a group of children with autism, with current or previous gastrointestinal complaints. Secondly, we examined whether children with autism had an abnormal glucagon-like peptide-2 (GLP-2) response to feeding. Results were compared with sibling controls…

Previous researchers have used stimulus preference assessment (SPA) methods to identify salient reinforcers for individuals with developmental disabilities including tangible, leisure, edible and olfactory stimuli. In the present study, SPA procedures were used to identify potential auditory reinforcers and determine the reinforcement value of…
