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…

The transition to adulthood is a significant step in every individual's life. Specifically, for individuals with disabilities, the transition process requires targeted planning for specific adulthood outcomes (e.g., employment, higher education, living skills, social skills, and community preferences). As such, parent and professional voices and…

The purpose of this study was to explore the phenomenon of belonging from the perspective of Cora, a school-aged child with an intellectual disability and significant support needs. Multiple data sources, including interviews, observations, field notes, and visual aids were coded and analyzed. Findings from the study illuminated how Cora's…

Children with autism spectrum disorder (ASD) who have limited spoken communication skills are commonly taught to mand by exchanging picture symbols. Competent manding via symbol exchange relies on conditional discrimination--that is, selecting the picture symbol that corresponds to the desired reinforcer. Picture Exchange Communication System…

Restricted and repetitive behaviors (RRB) are observed in young children with intellectual and developmental delays or disabilities (DD) including autism spectrum disorders (ASD). Self-injurious behavior is often considered an extreme form of RRB, but the nature of the relation between SIB and other forms of RRBs is not completely understood.…

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…

Parents play a central role in their child's development and learning. Parents of children with developmental disabilities have the added challenge of wading through additional services and engaging with professionals to support this process. As families navigate the educational system, this journey includes engaging with a team of people to…

Children with intellectual and developmental disabilities (IDD) frequently engage in escape-maintained problem behavior, which can limit their access to academic instruction and lead to placement in more restrictive educational settings. While there are function-based interventions to treat escape-maintained problem behavior, these interventions…

Executive functioning abilities have been associated with important behaviors such as adaptive skills and cognitive abilities in children with and without disabilities. Executive functioning has primarily been measured as a strong predictor of later abilities in children with neurodevelopmental disabilities, such as attention-deficit/…

Purpose. This quantitative study examined parent perceptions regarding augmentative and alternative communication (AAC) interventions for their children with autism to determine if, according to parent perceptions, a relationship existed between AAC and functional communication. Those faced with cognitive and developmental delays like autism face…

Autism spectrum disorder is generally regarded as complex, neurologically based, developmental disability that typically has its onset early in life (Myles & Simpson, 2001). Autism spectrum disorder is considered a universal disorder that affects children across all socioeconomic and educational levels (Wilkinson, 2010). Autism spectrum…

Intelligence tests and adaptive behavior scales measure vital aspects of the multidimensional nature of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability, and both are frequently used conjointly in the assessment and identification of other developmental disabilities. The…

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that…

Everyone, including children with developmental disabilities, encounters stimuli they find aversive every day (e.g., the sound of a classmate tapping their pencil). These aversive stimuli may not be problematic for typically developing individuals, because they learn to behave in ways that allow them to escape or avoid this aversive stimulation.…

This study focused on the experience of parents concerned with child social behavior and the perception of bibliotherapy as an intervention. Using a qualitative phenomenological approach, four families raising children between the ages of 4-12 participated in a series of interviews. The children's social needs varied, but parent concerns were…
