In this article, the authors challenge professionals to re-examine assumptions about basic concepts and their implications in supporting adults with intellectual and developmental disabilities. The authors focus on decisions with significant implications, such as planning transition from school to adult life, changing living environments, and…

A limitation associated with communication-based interventions for problem behavior is the potential for requesting reinforcement at high rates. Multiple-schedule arrangements have been demonstrated to be effective for controlling rates of responding (Hanley, Iwata, & Thompson, 2001). In the current study, we extended previous research by teaching…

Almost 300,000 children in the United States from birth to 3 years of age are affected by a developmental disability. Disabilities have a lasting effect on a child's development and, in turn, may have a psychosocial impact on the child's family. In addition, the limitations of a child with a disability are often related to family members' stress,…

Although many researchers have investigated emotional and behavioral difficulties in individuals with Williams syndrome, few have used standardized diagnostic assessments. We examined mental health problems in 92 adults with Williams syndrome using the Psychiatric Assessment Schedule for Adults with Developmental Disabilities--PAS-ADD (Moss,…

Skin-picking is a type of self-injurious behavior involving the pulling, scratching, lancing, digging, or gouging of one's own body.

While there are several reports showing that skin-picking is common in individuals with developmental disabilities, knowledge…

Parental involvement has been studied in the field of education since the 1970s. Scholars assert that parental involvement affects students' achievement and performance (Christenson, Rounds, & Gorney, 1992; Epstein, Sanders, Simons, Salinas, Janson, & Van Voorhis, 2002; Fan & Chen, 2001; Herman & Yeh, 1983; von Voorhis, 2003).…

The slogan "Nothing About Us Without Us" has been used by disability rights activists to argue that any activity that affects people with disabilities should involve people with disabilities in leadership roles. At the University of New Hampshire, several graduate and undergraduate courses dealing with disability issues were co-taught by…

Aim: To estimate the prevalence of cerebral palsy (CP) and the frequency of co-occurring developmental disabilities (DDs), gross motor function (GMF), and walking ability using the largest surveillance DD database in the US. Methods: We conducted population-based surveillance of 8-year-old children in 2006 (N = 142,338), in areas of Alabama,…

Williams-Beuren syndrome (WBS) is a genetically determined neurodevelopmental disorder caused by a heterozygous deletion of 26-28 genes on chromosome band 7q11.23. During the past few years, researchers and clinicians have significantly contributed to define the phenotype of the syndrome, including its cognitive and behavioral aspects. However, it…

The number of children receiving cochlear implants (CIs) with significant disabilities in addition to their deafness has increased substantially. Unfortunately, children with additional disabilities receiving CIs have largely been excluded from studies on cochlear implant outcomes. Thus limited data exists on outcomes in this population to guide…

This longitudinal study focused on the effects of two different principles of intervention in children at risk of developing dyslexia from 5 to 8 years old. The children were selected on the basis of a background questionnaire given to parents and preschool teachers, with cognitive and functional magnetic resonance imaging results substantiating…

Persons with intellectual disability may encounter difficulties in making choices and expressing preferences because of restricted communication skills or a tendency to acquiesce. In addition, many studies provide evidence that these persons have less opportunity to make choices and express their preferences. The aim of this study was to conduct a…

The Research and Training Center on Community Living at the University of Minnesota reports that the number of people living in large state run institutions decreased from 117,147…

Purpose: To provide clinicians with evidence-based strategies to facilitate early speech development in young children who are not readily imitating sounds. Relevant populations may include, but are not limited to, children with autism spectrum disorders, childhood apraxia of speech, and late-talking toddlers. Method: Through multifaceted search…

The current study examined whether stimuli of different preference levels would be associated with different amounts of work maintained by the stimuli, as determined through progressive-ratio schedule break points. Using a paired-choice preference assessment, stimuli were classified as high, moderate, or low preference for 4 individuals with…
