Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were…

The aim of this study was to investigate the effect of a precision teaching (PT) framework on the mathematical ability of students with intellectual and developmental disabilities. We also examined if students of moderate mathematical ability could perform as well as their peers with fewer difficulties with their math skills. Sixteen students…

We evaluated the effectiveness of an online training on palliative care knowledge and self-efficacy among staff working with people with intellectual and developmental disabilities (IDD) using a one-group pretest-posttest design. Staff from four nonprofit residential and day services organizations in a U.S. Midwestern state participated. Among 132…

Background: The role of domain-general short-term memory (STM) in language development remains controversial. A previous finding from the HelSLI study on children with developmental language disorder (DLD) suggested that not only verbal but also non-verbal STM for temporal order is related to language acquisition in monolingual children with DLD.…

The current meta-analytic review analyzed 43 studies published in English, Chinese, and Japanese to determine the effects of caregiver involvement for promoting communication skills of individuals with ASD and IDD. Tau-U effect sizes, the Kruskal-Wallis H test, and the Dunn post hoc test were employed to calculate for moderator analyses: child…

An increasing number of investigations have described various interventions to promote the emergence of derived responding within the relation of sameness for individuals with autism and other intellectual and developmental disabilities. Systematic searches identified 53 studies published since 2013 that met inclusion criteria. These studies were…

More than half of the students with visual impairment (VI) have an additional developmental disability (DD) in the United States. Young children with VI and DD are at risk for language delay and these children need planned learning experiences to increase their language skills. Teachers of students with VI (TVI) have received training and special…

Children with developmental disabilities and complex communication needs who use augmentative and alternative communication (AAC) have limited opportunities to communicate and few trained conversation partners to interact with. Research literature on interventions utilizing AAC devices and systems to increase communication skills overwhelmingly…

Purpose: This study investigated the production of tense and subject-verb agreement in Palestinian Arabic-speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method: Participants were 14 children with DLD aged 4;0-7;10 and…

Skinner (1957) differentiated the roles of the speaker and the listener in a verbal encounter. Although not extensively emphasized, Skinner suggested an individual often behaves verbally even when responding as a listener. Children diagnosed with autism spectrum disorders (ASD) often display the absence of important, and basic verbal repertoires…

This issue, "On Counting What Matters: Finding Adults With Intellectual and Developmental Disabilities in Population Health Data," presents an overview of health surveillance research for people with intellectual and developmental disabilities (IDD) in the United States. Although public health now conducts surveillance of people with…

Background: School experience is an important part of the life of children with developmental disabilities (DD) and their families. Research suggests that parents of children vary in their level of satisfaction with their child's school, but methodology and results have varied and no consistent reliable measure of school satisfaction exists. This…

Implementation science examines the process of how programs are put into action to produce outcomes and represents an emerging approach for analyzing the utilization of evidence-based practices (EBPs) in school settings. When EBPs are implemented effectively, they result in positive student outcomes. The "Self-Determined Learning Model of…

Background: Children and adults with developmental disability frequently require either aided or unaided alternative and augmentative communication (AAC). Key word sign (KWS) involves using natural gesture and sign language to support the key words in spoken utterances. The purpose of this study was to determine whether communication partners of…

Background: People with intellectual developmental disorders have significant health disparities and a lack of proper attention to their health needs. They have been underrepresented in scientific research, and very few studies have been carried out using a representative randomized sample. The aim of this study was to describe the methods used in…
