Physical activity has many benefits, but many individuals with developmental disabilities fail to exercise regularly. Procedures in which consequences were arranged for exercising, alone or as part of a treatment package, have consistently increased physical activity by members of this population. We review 19 studies that arranged such…

Resilience is a burgeoning focus in health research; yet, researchers have varying conceptual and methodological approaches to understanding resilience across populations. Consequently, there is little consensus on the definition or operationalization of resilience. The objective of the present study was to conduct a scoping review of qualitative…

Naturalistic language interventions are commonly recommended to educators when teaching children to reliably share their wants, interests, and feelings with others. Recommendations include providing focused attention on a child and embedding multiple instructional opportunities within and across activities. Although such practices are commonly…

Statistical learning is a key concept in our understanding of language acquisition. Ample work has highlighted its role in numerous linguistic functions--yet statistical learning is not a unitary construct, and its consistency across different language properties remains unclear. In a meta-analysis of auditory-linguistic statistical learning…

Background: Subjects with intellectual disability (ID) are vulnerable to experience psychiatric disorders. The present authors performed a systematic review and meta-analysis to estimate the prevalence of co-occurring psychiatric disorders, excluding co-occurring autism spectrum disorders, in subjects with intellectual disability. Method: The…

Positive Behaviour Support is an applied behaviour analytic system of support that is utilised in schools and in residential care settings for children and adults with disabilities who engage in challenging behaviour. Implementation fidelity depends on appropriate staff training and organisational behaviour management. A systematic literature…

The present systematic review examines what factors determine when, how and to what extent previous linguistic experience (from the first language, second language or both languages) affects the initial stages and beyond of adult third language (L3) acquisition. In doing so, we address what a bird's eye view of the data tells us regarding…

Despite the explosive growth in stereotype threat (ST) research over the decades, a substantive amount of variability in ST effects still cannot be explained by extant research. While some attribute this unexplained heterogeneity to yet unidentified ST mechanisms, we explored an alternate hypothesis that ST theory is often misspecified in…

We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

The persistence of disappointing employment outcomes for youth and adults with autism spectrum disorder (ASD) indicates the importance of efforts to prepare them for the workplace. We conducted a systematic review of intervention/follow-up intervention studies on employment skills and outcomes for youth and adults with ASD. We reviewed 39 studies…

Background: Sexual violence is associated with significant morbidity and mortality. The incidence of sexual violence against adults with intellectual disability is significantly higher than in the general population. The aim of this systematic review and qualitative meta-synthesis was to explore the barriers faced by adults with intellectual…

The limited literature on the gifted and talented in university education reveals the importance of investigating relevant issues and directions, given that this human resource should be nurtured for both individual and national development. This review investigates issues relating to definitions, methodologies, and theoretical interpretations,…

We conducted a comprehensive review of the literature to establish the evidence base for using visual activity schedules (VAS) with individuals with intellectual disability. Literature published after 2005 was evaluated for quality using the criteria developed by Horner et al.; a total of 14 studies were included as acceptable. Findings suggest…

Dialogic reading (DR) is an evidence-based practice for young children who are typically developing and at risk for developmental delays, with encouraging evidence for children with disabilities. The purpose of this review was to comprehensively evaluate the evidence base of DR across early childhood settings, with specific attention to fidelity…

Individuals with autism spectrum disorder face significant challenges entering the workforce; yet research in this area is limited and the issues are poorly understood. In this systematic review, empirical peer-reviewed studies on employment programmes, interventions and employment-related outcomes in individuals with autism spectrum disorder over…
