Evaluating A Video Peer-Modeling Intervention On The Acquisition And Maintenance Of Social Skills For Adults With Autism In A Transition Setting, Adam K. Hammond

Theses and Dissertations

This study evaluated the use of a peer video modeling and prompting intervention used to teach three adults with autism to give a specified verbal and physical response when greeted. This intervention used a six-step task analysis to verify correct completion of the target behavior. At baseline, each of the three participants gave little to no response when greeted but after the video modeling and prompting intervention all three had acquired at least five out of six (83%) of the target behavior steps. Follow-up probes demonstrated that all three of the participants had maintained at least 4 out of 6 …

Prosodic Pitch And Intensity In Autistic Individuals, Cassidy Gooch

Theses and Dissertations

This study is an examination of how prosodic pitch and intensity compare in autistic individuals and neurotypical individuals. Ten-minute recordings of casual conversation were taken and analyzed. Participants included 11 autistic individuals and 11 neurotypical individuals with six males and five females in each group. The Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2; Lord et al., 2012) prosody rating scale was used to collect a perceptual evaluation of each participan's prosody, and Praat acoustic analysis software was used to collect measures of pitch and intensity over the 10-minute period to investigate how speech characteristics change with conversation partner familiarity. Results …

Understanding Gender Identification Within Individuals With Autism Using The Bem Sex-Role Inventory, Zackery Alan Cusworth

Theses and Dissertations

Gender is a socially derived construct that is taught and understood at young ages. However, not every individual has the same social skills to understand these seen and unseen social cues about gender. The Bem Sex-Role Inventory was given to adult individuals with autism in the United States to better understand their masculine, feminine, and androgenous perceptions. These data were then compared to the original Bem Sex-Role Inventory general population study to see if there were any differences. The data show that males with autism had lower masculine scores and higher feminine scores than males in the general population. Females …

Behavioral And Eye-Movement Correlates Of Item-Specific And Relational Memory In Autism, Greta Nicole Minor

Theses and Dissertations

Recent work has challenged past findings that documented relational memory impairments in autism. Previous studies have often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impaired in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals. Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants …

Exploring Levels Of Autism Symptom Support After Eligibility Determinations, Zachary Bella

Theses and Dissertations

The identification of autism spectrum disorders (ASD) occurs in educational and health settings. Many children with autism will only receive a classification of autism in the educational setting (Esler et al., 2022, Pettygrove et al., 2013, Wiggins et al., 2020). There is significant overlap between the early intervention offered to children with autism in health settings and what is provided through Individualized Education Programs (IEPs) (National Autism Center, 2009; Morset et al., 2010). However, there is an increasing trend of children with autism being classified with significant developmental delay (SDD) instead of autism initially in schools and the impact of …

Parent Facilitation Of Child Emotion Regulation In Autism Spectrum Disorder, Aimee K. Rovane

Theses and Dissertations

Parents play a substantial role in their children's emotional regulation (ER) abilities, promoting both adaptive and maladaptive development. Children with autism spectrum disorder (ASD) often have difficulties regulating their emotions, manifesting in externalizing behavioral issues (Mazefsky & White 2014). Though there are many similarities to parents of typically developing (TD) children, parents of children with ASD facilitate their children's ER development (i.e., emotion socialization) in response to unique challenges, often developing resiliency but other times contributing to their children’s dysregulation and behavioral challenges. Using Morris et al.'s (2007) Tripartite Model of Family Impact of Children's Emotion Regulation and Adjustment as …

The Effects Of A Peer-Mediated Social Skills Intervention On Children With Autism Spectrum Disorder, Shannon Elizabeth Mcconaghie

Theses and Dissertations

The purpose of this study is to analyze the effects of a peer-mediated social skills intervention (PMI) on children 6-12 years of age diagnosed with autism spectrum disorder (ASD). Current literature discusses the effects of peer-mediated social skills interventions for children with ASD in schools and on the playground but has not been conducted in an Applied Behavior Analysis (ABA) clinic or in an Early Childhood Education/ABA-integrated preschool. Three dyads, each consisting of a typical peer and a target child diagnosed with ASD, participated in this study. The frequency of participants' initiations, responses, and continuations were collected throughout all phases, …

Pivotal Response Treatment To Decrease Challenging Behavior And Increase Functional Communication In Preschool Children With Developmental Delays, Kalie Alexandra Gilmour

Theses and Dissertations

After a review of the literature on Pivotal Response Treatment (PRT) in young children with developmental delays, less was known on its effects on challenging behavior and functional communication in preschool age children receiving services in a traditional public school. A multiple baseline design across three participants was used to evaluate the effects of PRT on the functional communication of three preschool students with developmental delays. Based on a functional analysis, we also observed the effects of PRT on challenging behavior. A visual analysis of the data revealed a functional relation between PRT and functional communication and provided promising evidence …

Behavioral And Physiologic Relationships Between Sensory Processing, Attention, And Prediction In Autistic Children: An Eye Tracking Study, Courtney Hunter

Theses and Dissertations

Autism spectrum disorder (ASD) prevalence has risen to one out of every 36 children born in the United States being diagnosed. Many individuals diagnosed experience sensory processing difficulties that make life challenging for them and their caregivers. However, there is no clear consensus on why sensory processing issues occur. Previous research has linked attention function to atypical sensory processing. Our study aimed to understand potential underlying mechanisms and correlates of this relationship. We theorized that prediction is a key contributing factor to how attention and sensory processing interact. The purpose of this study was to examine the relationship between sensory …

Emotion, Sensory Processing, And Prosody In Neurotypical And Autistic Young Adults, Annika Henderson

Theses and Dissertations

There is a paucity of research regarding autistic adults, yet as autistic individuals grow to adulthood, they are often met with several barriers because of their differences from the neurotypical (NT) population. Given the demands of adult social interaction, some of the social difficulties experienced by autistic adults are likely related to emotion processing and prosody function. With sensory processing differences added as a diagnostic criterion for autism within the last decade, an investigation into its relationship with emotional processing, another marked difficulty for this population, is warranted. There are logical connections between sensory processing, emotion, and prosody, such that …

A Longitudinal Look: How Sleep Impacts Suicidal Thoughts And Behaviors In Autism And Social Anxiety, Lindsay Jacalyn Regehr

Theses and Dissertations

Crucial research about suicidal thoughts and behaviors is often done in a cross-sectional manner that only considers limited risk factors. This research is limited in scope and rarely produces meaningful results to inform treatment. This study uses a longitudinal design to follow 93 participants over approximately 6 months. Participants are individuals with autism and social anxiety who were part of high-risk groups for suicidality, sleep problems, and social isolation. Participants recorded their sleep patterns and suicidal thoughts daily via the phone app MetricWire and continuously wore a GENEActiv actigraphy device to tract their objective sleep patterns. The Columbia Suicide Severity …

Behavioral Skills Training For Reducing Challenging Behaviors In Students With Down Syndrome With Or Without Co-Occurring Autism Spectrum Disorder, Jacqueline Tudor

Theses and Dissertations

This applied dissertation was designed to improve the effectiveness of professional educators in using the methodology of functional behavior assessment (FBA) and function assessment-based intervention (FABI) to reduce challenging behaviors exhibited by students with Down syndrome (DS), or a dual diagnosis of Down syndrome and autism spectrum disorder (DS-ASD). Educators often rely on traditional classroom management methods which curtail disruptive behaviors without determining the reason why the behavior is occurring. The study examined the effects of utilizing a behavioral skills training program of instruction, modeling, rehearsal, and feedback in the methodology of FBA and FABI.

The research was conducted using …

Evaluating The Effects Of Video Modeling And Visual Supports On Preschoolers’ Compliance With Dental Procedures, Karly L. Orsi-Cordova

Theses and Dissertations

Individuals with autism are reported to visit the dentist infrequently. Infrequent visits to the dentist may result in a higher occurrence of caries, and it is, therefore, imperative for children with autism to visit a pediatric dental practice routinely. Some basic behaviormanagement techniques, such as live modeling and reinforcement strategies, have been used with patients with autism. The addition of techniques derived from applied behavior analysis, such as video modeling and visual supports, may increase patients’ compliance with dental procedures. Specifically, the use of visual supports and video modeling warranted further investigation on the efficacy of improving behavior during dental …
