The Effectiveness Of Equivalence-Based Instruction On Time-Telling Skills In Children With Moderate Developmental Disabilities Including Autism Spectrum Disorder And Intellectual Disability, Rongzhi Li

Theses and Dissertations

The purpose of this study was to evaluate the effectiveness of equivalence-based instruction (EBI) on teaching time-telling skills to children with moderate developmental disabilities including autism spectrum disorder (ASD) and intellectual disability. Three children with ASD or intellectual disability participated in the study. The experiment was conducted using a concurrent multiple baseline design across subjects. During the acquisition training, each participant was taught 24 discrimination relations including matching 12 picture analog clock faces and 12 printed digital clocks to their dictated times. After the training, the participants were assessed to see whether their visual-visual responses (transitivity relations) and oral naming …

The Autistic Adult's Perspective On Genetic Testing In The Prenatal And Cancer Settings, Robin Lisa Urban

Theses and Dissertations

Prenatal and cancer genetic tests are recommended by many professional medical organizations. Previous studies have shown that autistic adults have a negative opinion towards genetic testing for autism but have not explored if this sentiment is shared for other types of genetic testing. We used a descriptive, web-based survey of autistic adults to assess their attitudes towards prenatal and cancer genetic testing (n=36). Our data showed that overall attitudes towards prenatal and cancer genetic testing are positive. Notably, participants had slightly more positive attitudes towards prenatal genetic testing related to neurodevelopmental disorders when compared to testing for disorders primarily affecting …

Systematic Review Of Digital Activity Schedule Use In Individuals With Autism And Intellectual Disability, Adelaide Wahlquist Hammond

Theses and Dissertations

The purpose of this systematic review of using digital activity schedules as an intervention in individuals with autism spectrum disorder and intellectual disabilities is to determine to what extent the current research shows it to be an effective intervention. For articles to be included in this review, they had to use a digitally presented activity schedule, the activity schedule could not be a task analysis of a single activity or a group visual schedule, and the intervention must have been carried out with individuals with autism or intellectual disabilities. Studies meeting the inclusion criteria totaled 17 studies with a total …

Communication Between Young Adults And Their Siblings With Autism, Shane Morgan Petersen

Theses and Dissertations

As adolescents transition into young adults, many changes take place within family relationships as young adults move away from home. Young adults may be living away from parents and siblings for the first time and will establish communication patterns that can affect the rest of their life (citation). Relationships largely rely on communication in which young adults and their siblings with autism may experience changes in communication patterns as they move away from home. This study examined six young adults who all have a sibling with autism with whom they are no longer living. An examination of how close these …

Toward Overcoming The Double Empathy Problem: Bridging Autistic And Neurotypical Minds Through Science And Art, Elizabeth Rose Bessey

Theses and Dissertations

Historically, autistic people have been portrayed as lacking empathy. However, more recent research reveals mutual, rather than one-sided, gaps in empathy between autistic and neurotypical (NT) people. Decreased empathy can lead to marginalization and even violence, usually toward those in the minority. Regardless of diagnosis, however, there are fundamental aspects of the human experience upon which empathy could be built. In the present study, we explored commonalities and differences in how autistic and NT individuals experience comfort and discomfort. Semi-structured interviews were conducted to discover the causes, emotions, and reactions to comfortable and uncomfortable social situations and environments across autistic …

Neurobiological Underpinnings Of Autistic Traits, Sensory Processing, And Mental Health In Young Adult Males And Females, Miranda Jane Mcquarrie

Theses and Dissertations

Females may present with autism more frequently than is diagnosed, due, in part, to autistic trait and sensory processing differences. Unfortunately, recruiting enough autistic female participants is difficult, because of such underdiagnoses. By approaching autism as a continuous variable, neurotypical (NT) individuals can be studied to better understand autistic individuals. Thus, to examine potential neurobiological underpinnings of sex-based behavioral profiles, we recruited 52 NT individuals (22 male; 30 female). Participants underwent resting-state functional magnetic resonance imaging (fMRI) to examine how functional network connectivity (via group independent components analysis) underpinned overall male/female differences in previously measured behavioral autistic trait and sensory …

Hospital Provider Knowledge Of Behavioral Function And Management Of Severe Behavior For Patients With Autism, Giovanna Salvatore Devito

Theses and Dissertations

Hospital patients with autism spectrum disorder (ASD) may engage in various topographies of severe behavior, with higher rates of restraint implemented than for their neurotypical counterparts. Qualitative research suggests that physician knowledge of function-based intervention is limited. Multidisciplinary behavior management teams were developed to decrease restraint across general hospital patients. In Study 1, the research team developed the Knowledge of Behavioral Function (KoBF) survey measure, using an iterative user-centered development process and administered the measure to multidisciplinary physicians and trainees. Results indicated low knowledge of behavioral function, with a mean percent correct of 66.60% on close-ended survey items and 14% …

Trauma-Informed Mindfulness-Based Stress Reduction To Increase Family Quality Of Life For Mothers Of Children With Autism: A Pilot Study, Carol May Vaughn

Theses and Dissertations

Mothers of children with autism have a higher rate of stress than mothers of neurotypical children and mothers of children with other disabilities. This impacts their family quality of life. This study aimed to show that by teaching mothers trauma-informed mindfulness-based stress reduction techniques they were able to switch their perspectives and feel that they had increased the relationships with their child with autism and increased the rating they give their family quality of life. The participants were recruited using word of mouth and through distribution of posters to autism communities following approval of the experiment through the institutional review …

Prosodic Speech Rate, Utterance Duration, Interruption Rate, And Turn-Taking Latency In Autistic And Neurotypical Adults, Grace Madeline Bell

Theses and Dissertations

The purpose of this study was to examine the following prosodic elements: speech rate, turn-taking latency, number of interruptions, and utterance duration across two groups' neurotypical and autistic young adults. Furthermore, the end goal of this study is to help provide a baseline and clinical application of prosodic differences between autistic and neurotypical adults. Speech samples were collected from 11 neurotypical and 11 autistic young adults from the ages of 18-26. Speech samples were recorded responses from a 10-minute interview between two research assistants and the autistic or neurotypical individual. Using Praat software, speech samples were analyzed and used to …

Using Video Modeling With Feedback To Teach Courtship Behaviors To An Autistic Young Adult: A Single Subject Design, Alyssa Paige Goodman

Theses and Dissertations

The purpose of this study was to assess the effectiveness of video-modeling with feedback on the development of courtship behaviors in an autistic individual. A concurrent multiple baseline across behaviors design was used to examine the impact of this intervention on three target behaviors: asking someone on a date, responding to acceptance, and handling rejection. The intervention consisted of showing the participant video models in which volunteers demonstrated the three target courtship behaviors. Following three, four, and five baseline observations for each target behavior, corresponding video models were introduced for each of the behaviors. Following the viewing of video models, …

A Study On Reducing Motor Stereotypy With Response Interruption And Redirection Using Functionally Matched And Unmatched Stimuli, Alana Fallucca

Theses and Dissertations

This applied dissertation was designed to expand the scope of existing literature on the use of response interruption and redirection intervention with functionally matched and unmatched stimuli to reduce motor stereotypy in children with autism. While response interruption and redirection is an effective, evidence-based strategy for the reduction of vocal and motor stereotypy, it requires interruption of each instance of stereotypic behavior and implementation of an alternative behavior. This process can be laborious, implementation of which depends upon the frequency of stereotypy. To mitigate the intervention difficulties with response interruption and redirection implementation, a single-step functionally matched stimulus that is …

Evaluation Of Effects Of Behavioral Skills Training In Promoting Three Social Skills In Young Child With Autism: A Multiple Probe Research Design Study, Jennifer Rey

Theses and Dissertations

This applied dissertation was designed to evaluate the effectiveness of the behavioral skills training model in teaching one 4-year-old child with autism to greet others, use an appropriate tone of voice, and use anger control. Moreover, this study assessed the maintenance of newly acquired social skills relying on a multiple probe research design. It was hypothesized that with the use of behavioral skills training the acquisition of the appropriate social skills at an early age would allow the child to engage with peers and adults in the training environment and later in a variety of social situations across other settings …

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 …

Estimating Hemispheric Specialization In Autistic And Neurotypical Individuals, Madeline Peterson

Theses and Dissertations

While the brain appears to be symmetrical, macroscopic differences or asymmetries between the two hemispheres emerge through careful quantitative study. Functional asymmetries can accompany these structural asymmetries, and these can be a reflection of hemispheric specialization, or the predominant hosting of macroscale functional network and its accompanying functional properties by a given hemisphere. Prior work has identified the specialization of language to the left hemisphere, visuospatial attention to the right hemisphere, and a dual specialization of executive control to both hemispheres. However, it is largely unknown how specialization is characterized at an individual level, particularly in terms of identifying the …

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 …

Ally Mediation Of Social Media Use For Adults With Autism, Spring S. Cullen

Theses and Dissertations

Previous research has highlighted the unique challenges young Autistic adults face when using social media. We extend this work by analyzing how guardians and allies, such as service providers, mediate the social media usage of young Autistic adults in order to address and mitigate online risks. Based on analysis of interview transcripts (8 young adults on the Autism spectrum, 4 parents, 10 staff members), we uncover the mediation tactics used, how they differ based on the ally's relationship with the individual, and the tactics' varying degrees of effectiveness. The findings of this research contribute to the literature by informing the …

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 …

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, …

Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa

Theses and Dissertations

Between 4.8% and 26% of adults presenting to gender dysphoria clinics have an autism diagnosis. Both autistic people and gender-diverse people have higher rates of mental health conditions including anxiety and depression and more difficulties with executive functioning, all of which impact quality of life. Some work suggests that gender affirmation leads to better mental health outcomes, including better executive functioning, but this has not been studied directly in autistic adults who identify as gender-diverse or transgender. As such, we elected to explore the relationships among these variables at this intersection of gender diversity and autism. In a sample of …

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 …

The Congruence Of Parent-Teacher Relationships For Students With Autism: The Role Of Teacher Efficacy And School Climate, Morgan Johnson

Theses and Dissertations

Ecological Systems Theory (Bronfenbrenner, 1979) can be used as a framework to examine the importance of communication and collaboration among parents and teachers as both are important stakeholders in the field of education. Parent-teacher relationships are critical for autistic students particularly due to individualized education plans and the provision of special education services (IDEA, 2004). The current study examined relationships between parent-teacher dyads in terms of congruence, the degree to which both parties are in agreement about their relationship. This study was unique in its mixed methods design, combining quantitative and qualitative data, as well as its use of dyadic …
