To date, health related quality of life (QoL) has not been systematically evaluated in youth with fragile X syndrome (FXS), the most common single gene cause of autism and the most common inherited form of developmental disability. We describe QoL data gathered using the Pediatric Quality of Life Inventory (PedsQL) completed online by 364 parents…

This study takes an ecological approach to examine how children with developmental language disorder (DLD) interact with their classmates within early childhood special education (ECSE) inclusive classrooms. Participants were 124 children with DLD, 56 children with other disabilities, and 247 typically developing children (M[subscript…

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during…

Purpose: The purpose of this narrative review was to examine the evidence for imitation training for targeting grammar in children with developmental language disorder. Method: Studies investigating imitation training were compiled from two databases--PsycINFO and Linguistics and Language Behavior Abstracts--as well as from reference lists of…

Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009),…

The purpose of this study was to investigate the effects of explicit Direct Instruction to teach letter sound correspondence to students with developmental disabilities. Additionally, this study sought to provide a basis for further research for a population of students with low incidence disabilities who are oftentimes overlooked in the field of…

Various types of augmentative and alternative communication systems have been successfully used to enable functional communication in children with developmental disabilities. The effects of such systems on natural speech production have also been investigated, but few studies have explored the effects of specific procedures aim at inducing…

Postsecondary education programs (PSEs) are becoming increasingly available for young adults with intellectual and developmental disabilities across the United States. Positive interactions between young adults and their families and professionals, and collaborative family-professional interactions can enhance transition outcomes for people with…

Early intervention services are an important federally funded program for families with children under three years of age who may be diagnosed with or are at risk of developmental delay or disability. The program's impacts can be profound: Early intervention helps strengthen cognitive, motor, and language skills; reduces the likelihood of…

In this paper, we draw on the 'dilemma of difference' to discuss the dangers and affordances of diagnosis within two of the most prevalent, yet under-supported, disabilities affecting school-age children: Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Language Disorder (DLD). The dilemma that exists between denying and thereby…

Identifying the early signs of developmental disability is important for ensuring timely diagnosis and early intervention. Day-care workers may be in a prime position to notice potential developmental deviations, but it is unclear if they can accurately recognize subtle early signs of atypical development. Sixty day-care workers examined…

Background: The ability to learn new words is critical in the development of oral and written language, and significantly impacts engagement in social, academic and vocational situations. Many studies have evaluated the word-learning process in people with developmental language disorder (DLD). However, methodologies for assessment are…

This study presents a meta-analytic review of serial rapid automatized naming (RAN) deficits in individuals with dyslexia relative to typical readers (based on 216 effect sizes comprising 8335 dyslexic readers, 14,083 age-matched controls, and 921 reading-matched controls). A random-effects model analysis indicated a large impairment in speeded…

Human sexuality encompasses aspects of physiology and emotions. The need for sociosexuality education for individuals with developmental disabilities (DD) is widely acknowledged; yet, there is little known about what topics of sexuality are presented. This review identified curricular content used in comprehensive, commercially available sexuality…

Challenges in collecting comprehensive health surveillance data on people with intellectual and developmental disabilities (IDD) are numerous. A number of important issues and strategies are discussed in the articles contained in this special issue of "Intellectual and Developmental Disabilities." In this article, we focus on the…
