This dissertation was designed to determine which behavior analytic intervention was more effective in the treatment and reduction of mouthing non-nutritive substances in children diagnosed with autism. This study included four participants in an A-B-A reversal design with a component analysis across four intervention phases. The study…

Social skills deficits are common for children diagnosed with an autism spectrum disorder (ASD). Research indicates there is a need to continue to find ways to support parents in enhancing social skills acquisition in their children with ASD. The present study evaluated the effects of using behavioral skills training (BST), delivered via mobile…

Caregivers of children with developmental delay (DD) or disabilities are at a higher risk of developing mental health problems like depression when compared to caregivers of children who are typically developing. Several factors, including child diagnosis and child challenging behavior, have been known to exacerbate caregiver risk for mental…

The prevalence of Autism Spectrum Disorders (ASD) has resulted in research on treatment efficacy, lending itself to quantitative analyses. In contrast, ethnographic studies have offered the benefits of analyzing lived experiences and exploring the uniqueness of ASD individuals. Using the Linguistic Ethnography (LE) perspective, this case study…

Providing early intervention and continuous service provision to children with autism spectrum disorder (ASD) and their families in Puerto Rico can be complex due to multiple factors including limited resources, difficulty accessing service providers, and yearly environmental impacts such as hurricanes (Chandra et al., 2021). Implementing…

Children with Developmental Delay (DD) and Autism Spectrum Disorder (ASD) experience challenging behaviors, including noncompliance, that impact individual and family functioning across settings. Due to developmental risk, parenting has emerged as being especially instrumental within this population, with positive parenting practices directly…

Children are being diagnosed with Autism Spectrum Disorder (ASD) at younger ages then historically represented (Guthrie, Swinford, Notke & Wetherby, 2013). Due to increased awareness of ASD and improved diagnostic tools, younger children are receiving Applied Behavior Analysis (ABA) at an early age ( Hertz-Picciotto & Delwiche, 2009). ABA…

There is a considerable gap between evidence-based interventions intended to support students with Autism Spectrum Disorder (ASD) and current classroom practice (Anderson et al., 2018; Artman-Meeker et al., 2015). Early childhood programs and educators are in crucial need of additional support and evidence-based services that address the growing…

Rule-governed behavior (RGB) is behavior that is controlled by verbal descriptions of contingencies rather than by direct contact or a history of direct contact with the contingencies. Humans rely on RGB to navigate a multitude of life experiences, and in doing so, we avoid direct contact with destructive or harmful contingencies or contingencies…

This dissertation is composed of two manuscripts that study the early development of infants at an elevated likelihood of an autism spectrum disorder diagnosis (EL-ASD). In the first manuscript, the language profiles (i.e., receptive dominant, expressive dominant, balanced) and the predictors of the language profiles are examined in infants at…

There are many different interventions available to individuals with autism, and the benefits of each therapy may vary for each student. Two vastly different treatments are discrete trial teaching (DTT) and the verbal behavior approach (VBA). While both are based in the principles of applied behavior analysis (ABA), VBA relies more on naturalistic…

Research in pre-college engineering education has been on a sharp rise in the last two decades. However, less research has been conducted to explore and characterize the engineering thinking and engagement of young children, with limited attention to children with special needs. Conversations on broadening participation and diversity in…

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/…
