Core vocabulary is defined as "lexical items that are accepted as being central and indispensable to language use" (Bell, 2012, p. 1). Use of core vocabulary is common amongst professionals who teach augmentative and alternative communication (AAC) to individuals with disabilities. Although the use of AAC is often classified as an…

Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose…

Background: Neurodiversity is increasingly discussed in relation to autism research and practice. However, there is a lack of scholarship concerning the neurodevelopmental condition of Developmental Language Disorder (DLD) and the neurodiversity movement. While this movement may hold opportunities for the DLD community, the application of the…

Primary reflexes are highly stereotypical, automatic movements comprising much of the motor repertoire of newborns. The current study examined rates of presence of five primary reflexes (snout, visual rooting, sucking, tactile rooting, and grasp) and variables predictive of their persistence for children with ASD (n = 35), developmental disability…

Developmental Coordination Disorder (DCD), also known as Dyspraxia, is an often overlooked or misdiagnosed disorder and little research exists on how it manifests among cognitively gifted children. The purpose of this study was to examine clinical profiles among 25 children diagnosed with DCD and identified as cognitively gifted to explore the…

This study aimed to better understand how autism spectrum disorder (ASD) and developmental coordination disorder (DCD) differ in types of praxis errors made on the Florida Apraxia Battery Modified (FAB-M) and the potential relationships between praxis errors and social deficits in ASD. The ASD group made significantly more timing sequencing errors…

Identifying infants at elevated likelihood for autism and other developmental differences in the first year of life remains a significant challenge. This study explored associations between behavioral differences in infancy and developmental outcomes in toddlerhood. We conducted a secondary data analysis of 256 infants with an older autistic…

Autism spectrum disorders and developmental coordination disorders are both associated with sensorimotor impairments, yet their nature and specificity remain unknown. In order to clearly distinguish the specificity between the two disorders, children with autism spectrum disorder or developmental coordination disorder presenting the same degree of…

As interest in derived relational responding has increased, so have the number of investigations evaluating interventions to promote the emergence of derived responding for individuals with autism, as well as other intellectual and developmental disabilities. However, much of the literature has focused on the relation of sameness, and less is…

Autism spectrum disorder (ASD) and Developmental Coordination Disorder (DCD) are distinct clinical groups with overlapping motor features. We attempted to (1) differentiate children with ASD from those with DCD, and from those typically developing (TD) (ages 8-17; 18 ASD, 16 DCD, 20 TD) using a 5-min coloring game on a smart tablet and (2)…

Autism is heterogeneous at many levels, including clinical symptoms and etiology. A key strategy in studying heterogeneous conditions is having large enough sample sizes to stratify into smaller groups that are more homogeneous. SPARK and Simons Searchlight are large and growing research cohorts of individuals with autism in the United States and…

Objective: Pragmatics can be defined as the appropriate use of language in social interactions. Children with Autism Spectrum Disorder (ASD) and children with Developmental Language Disorder (DLD) exhibit difficulties in pragmatic language (PL), but the nature and sources of these difficulties have not been fully investigated yet. The purpose of…

Background: Amongst the growing number of examples of inclusive dance programming, community-informed recommendations for inclusive dance are scarce. Our purpose was to develop recommendations for inclusive dance with dancers with the lived experience of autism, intellectual, or developmental disability, and the professionals who work with them.…

This study examined and compared the comprehension of Mandarin ditransitive constructions in children with developmental language disorder (DLD) and children with autism spectrum disorder plus language impairment (ALI). Eighteen children with DLD, 17 children with ALI, and 27 age-matched typically developing (TDA) children, participated in a…

Background: Sleep deprivation can decrease parental well-being and degrade mental and physical health in parents of children with chronic illness. The aim of this study was to explore the associations of sleep quality, psychological stress perception, and evening salivary cortisol concentration with self-esteem, optimism and happiness in parents…
