Children with developmental language disorder (DLD) regularly use the bare form of verbs (e.g., dance) instead of inflected forms (e.g., danced). We propose an account of this behavior in which processing difficulties of children with DLD disproportionally affect processing novel inflected verbs in their input. Limited experience with inflection…

Recommendations for achieving generalized instructional outcomes often overlook the capacity for generative learning. We sought to demonstrate how decontextualized and logically organized instruction would lead to derived and contextually appropriate recombinative generalization and arbitrarily applicable relational responding (AARRing) in…

Improving the ability to solve mathematical word problems is one of the most critical issues facing students with developmental disabilities, because it is directly related to their independent living skills. The purpose of this study was to propose a teaching model that implements augmented reality (AR) and video modeling (VM), and to validate…

Background & aims: Although the Picture Exchange Communication System (PECS) has been demonstrated to be an effective intervention to teach people diagnosed with autism spectrum disorder a functional communication system, the research indicates variability in PECS outcomes across people and studies. Therefore, the purpose of the current study…

Language disorder is characterized by difficulty with the comprehension and production of different aspects of language. School-aged children with developmental language disorder (DLD) and school-aged children with Down syndrome (DS) demonstrate similar deficits in the area of morphosyntax, which often creates barriers during social interactions…

This study examined the effects of using behavioral skills training (BST) to teach peer models to engage students with moderate to severe developmental disabilities in interactive play. Two separate multiple-baseline across participants designs were used to determine the effectiveness of BST on the peer models' implementation of the procedural…

Social deficits are often a core area of development for students in special education, thus schools are charged with providing social skills interventions. Although many strategies are available, few schools successfully employ evidence-based interventions for students with autism and related disabilities. A way to address these concerns while…

One concern raised about teaching content from the general education curriculum to students with intellectual and developmental disabilities is whether they generalize the skills learned to typical performance settings. We conducted a literature review of research studies that taught content from the general education curriculum and assessed…

Given the importance of social integration and participation in inclusive settings for young children with autism spectrum disorder (ASD), the purpose of this systematic review was to examine instructional outcomes and participant, teacher, group, and instructional characteristics that may be pertinent to successful group instruction for young…

Purpose: In a previous article, we reported that beginning treatment for regular past tense "-ed" with certain types of verbs led to greater generalization in children with developmental language disorder than beginning treatment with other types of verbs. This article provides updated data from that study, including the addition of data…

This paper compared the effectiveness and efficiency of using computer-assisted instruction (CAI) and teacher-implemented instruction (TII) to teach visual matching skills to students with autism spectrum disorder and/or other developmental disabilities. Four school-aged students participated in this study with an alternating treatment design. The…

Access to employment opportunities is associated with increased quality of life for people with intellectual and developmental disabilities; however, many adults with intellectual and developmental disabilities struggle to find employment. One reason they may have difficulty achieving employment is an inability to work independently.…

Adults with intellectual disability may not learn safety skills needed to maintain the safety of those within their communities. Basic life-saving skills are valued by community members and increase independent and integrated living and employment opportunities. This study used an instructional package consisting of modeling, task analysis, and…

Stay-Play-Talk (SPT) is a peer-mediated intervention used to increase social interactions between preschoolers with developmental disabilities and typically developing (TD) peers. This intervention has been found to be successful in increasing play and reciprocal conversation amongst children with and without disabilities. The following describes…

We performed a scoping review of literature on schools' transfer of rights practices under the Individuals with Disabilities Education Act (IDEA) with respect to students with intellectual and developmental disabilities. The review found only limited empirical evidence of how IDEA transfer of rights policies are implemented in schools and affect…
