Purpose: This study examined the frequency of code-switching by Spanish-English-speaking children as a function of language proficiency in each language and diagnosis (developmental language disorder [DLD] or typical language development [TLD]). Method: Sixty-two Spanish-English-speaking children, 5-7 years of age, participated in this study (24…

The inclusion of children with special educational needs into mainstream schools needs effort and cooperation by all those involved. Both educators and medical professions need to be skilled in identifying and supporting neurodiversity. This study explores the cross-professional understanding and support of four of the most prevalent…

This article investigates how a computer simulator for human interactions and a dyadic system in a pencil-and-paper environment can contribute to helping students with poor motor co-ordination, notably those with dyspraxia, to learn geometry. The aim is to design an alternative way to teach the subject, and to explore its effects on the learning…

The Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ-CA) is a parent-report screening instrument that identifies 3- to 4-year-old children who may be at risk for Developmental Coordination Disorder (DCD). We tested the criterion validity of the Little DCDQ-CA in a sample of preschool-aged children in the United States…

An acquisition criterion, more commonly known as "mastery criterion" is an instructor-established standard of performance that may signal the acquisition of a novel skill or the conclusion of a phase of intervention. When teaching new behaviors, researchers and practitioners in the field of Applied Behavior Analysis (ABA) apply some type…

The purpose of this qualitative retrospective case study was to measure the impact that intervention methods derived from Arwood's Neuro-Education Model had upon the learning and development of one young adult with moderate to severe developmental disabilities. One participant received the intervention methods over the course of 2 years from a…

Sleep problems are prevalent in children with neurodevelopmental disabilities and are associated with the expression of restricted and repetitive behaviors (RRBs). Children (n = 57) with autism spectrum disorder (ASD, n = 38) or developmental delay (DD, n = 19) participated in multiple assessments of intellectual ability, ASD symptoms, and RRBs (3…

Purpose: Children with developmental language disorder (DLD) experience difficulties with an important Theory of Mind milestone, namely, false belief (FB) reasoning. Their FB success relates to mastery of a linguistic structure that is also challenging for them, namely, sentential complements (e.g., "Claire says/thinks [that Santa Claus…

Parents are often responsible for educating their child about sexuality and relationships, yet many parents may not be aware of the sexuality-related topics to teach. Sexuality education is critical for children with autism and intellectual disabilities, who are often vulnerable to sexual abuse and other sexual behavior outcomes. Families teaching…

Lag reinforcement schedules have been shown in previous research to be an effective intervention for teaching verbal and nonverbal response variability to individuals with developmental disabilities. In more recent research, variability itself has been considered a reinforceable behavior in its own right (Susa & Schlinger, The Analysis of…

A better understanding of the factors associated with depression and anxiety in people with intellectual and developmental disabilities (IDD) is needed to provide guidelines for service providers, clinicians, and researchers as well as to improve the diagnostic process. The current study used a longitudinal dataset to explore demographic, health,…

Dysphagia is common in individuals with developmental disabilities. Little research exists on the impact of trainings aimed at improving Direct Care Staff's (DCS) use of safe eating and drinking practices. This article presents two studies using pre-and postexperimental design, evaluating online training to improve DCSs' knowledge and ability to…

Australian legislation requires teachers to make reasonable adjustments for students with disability, including those with Developmental Language Disorder. The Standards underpinning this legislation stipulate that students must be "consulted" about adjustments that are made. This is not common practice in Australian schools and there is…

This practical guide for teaching numeracy to children with a developmental disability is based on core concepts from the landmark Mathematics Recovery® text Teaching Number (aka 'the green book') that have been adapted for children with developmental disabilities. It sets out key principles of teaching and learning underpinning an evidence-based…

We examined undergraduate students' perceptions of peers with intellectual and developmental disabilities (I/DD) before and after participating in an inclusive book club on the college campus. Over a six-week period, undergraduate students and students with I/DD enrolled in the post-secondary education program at the university engaged in an…
