The current dissertation includes seven chapters. Chapter 1 includes my professional background and describes the experiences that led me to study restricted and repetitive behaviors. It also briefly describes my personal journey as an international graduate student. Chapter 2 is devoted to the rich literature that this dissertation is based on. The literature review covers both the foundational and most recent findings in the fields of sensory reactivity, restricted and repetitive behaviors, and autonomic activity, as well as the known relationships between these areas in autistic and non-autistic individuals. In Chapter 3, I describe in detail the methodology used in …

Teaching Siblings To Encourage And Praise Play: Supporting Interactions When One Sibling Has Autism, Holly R. Weisberg

Dissertations, Theses, and Capstone Projects

Sibling relationships may be strained when one sibling is typically developing (TD) and one has a diagnosis of autism spectrum disorder (ASD). TD siblings have been taught to encourage play in their siblings with ASD but there is limited literature examining the impact of intervention on the quality of the siblings’ relationships. In this study, we taught four TD siblings to encourage and praise play skills in their siblings with ASD as well as self-monitor those play skills. We measured changes in social-communicative behaviors during siblings’ interactions. All TD siblings learned the targeted play skills and increased social-communicative behaviors. Only …

An Evaluation Of An Application Designed For The Ipad® To Measure Stimulus Overselectivity For Future Use In Autism Research, Adrienne A. Fitzer

Dissertations, Theses, and Capstone Projects

Twenty-three college students participated in two studies evaluating an application designed to measure stimulus overselectivity in pictures depicting facial affect. We analyzed whether this application worked as designed by evaluating whether it could provide a robust analysis of the types of errors users make (e.g., by matching by the top features, the bottom features, or not by the top or the bottom features), and the extent to which the application worked to decrease selective responding in the event a user was not matching consistently by all features. We also evaluated if participant scores on the Autism Quotient and RAADS-14 could …

Development Of An Aba Tool Kit For Audiologists To Increase Hearing Aid Wear Time In Individuals With Autism, Lindsay Brown

Dissertations, Theses, and Capstone Projects

When working with individuals with the dual-diagnosis of hearing loss and Autism Spectrum Disorder (ASD), audiologists are often faced with unique challenges and must adapt their approach in order to more effectively address the needs of these individuals. Currently, there is only a small body of research focused on the special considerations required for appropriately fitting and utilizing amplification for children with the dual-diagnosis of hearing loss and ASD. Subsequently, recommendations and strategies for clinicians to implement when faced with these common challenges, specifically of hearing aid compliance and appropriate hearing aid wear time, are lacking. It is important to …

Exploring Influences On Autistic Identity Development In Adolescence And Early Adulthood, Ariana Riccio

Dissertations, Theses, and Capstone Projects

Personal identities grow and change across development, co-constructed and renegotiated within our environment, through our interactions, and by our relationships with the people and places around us. This dissertation aimed to explore the development of autistic identity in adolescence as influenced by parents, introduces a novel method for measuring emotions and autistic identity where participants rate their emotional responses to autistic experiences, and explores the influence that colleges and universities may have on autistic identity in young autistic adults.

In a study of 19 autistic adolescents and their parents, if and how parents disclosed an autism diagnosis to their child …

Objective Measures Of Electrophysiological Responses Of Children With Idiopathic Autism Spectrum Disorder And Phelan-Mcdermid Syndrome To A Contrast-Reversing Checkerboard, Chloe Brittenham

Theses and Dissertations

The heterogeneity of autism presents many challenges in understanding the disorder. The current study employs objective measures to examine visual evoked potential (VEP) responses of children with idiopathic autism (iASD) and Phelan-Mcdermid syndrome (PMS) to a contrast-reversing checkerboard in both long (60-second) and short (2-second) duration conditions.

The Effects Of Presession Attention On The Acquisition Of Tacts And Intraverbals, Mirela Cengher

Dissertations, Theses, and Capstone Projects

This study examined the effects of presession attention on the acquisition of tacts (Experiment 1) and intraverbals (Experiment 2) in children with Autism Spectrum Disorders. There were 3 conditions in each experiment. In the first 2 conditions, the experimenter first exposed the participants to a 15-min interval of either presession attention (PA) or no presession attention (NPA), then immediately conducted a teaching session. The third condition was a control condition, which involved no pressession interval or teaching procedures. The consequence for emitting tacts and intraverbals consisted of different forms of attention (e.g., praise and clapping). Across experiments, all participants acquired …

Cognitive And Affective Control Deficits In Adults With Autism Spectrum Disorder, Melissa-Ann Mackie

Dissertations, Theses, and Capstone Projects

Cognitive control constrains mental operations to prioritize information that reaches conscious awareness and is essential to flexible, adaptive behavior under conditions of uncertainty. However, cognitive control can be compromised by neurodevelopmental disorders such as autism spectrum disorder (ASD), which is characterized by the presence of social and communicative deficits, and restricted interests/repetitive behaviors. Although prior investigations have attempted to elucidate the nature of cognitive control deficits in ASD, whether there is an underlying deficit in cognitive and affective control associated with the symptom domains of ASD remains unclear. The present series of eight experiments presents an information theoretic framework for …

“For A Long Time Our Voices Have Been Hushed”: Using Student Perspectives To Develop Supports For Neurodiverse College Students, Kristen Gillepsie-Lynch, Dennis Bublitz, Annemarie Donachie, Vincent Wong, Patricia J. Brooks, Joanne D'Onofrio

Publications and Research

Although the challenges that autistic students face adapting to college are often pronounced, they are similar to the challenges that students with other disabilities face (e.g., difficulties with social interaction, self-advocacy, and executive functioning). However, extant evaluations of services for autistic college students are very limited despite an emerging literature examining supports for college students with a range of other disabilities. Given that many autistic students do not self-identify as autistic in college, and consequently might avoid autism-specific services, autistic students might benefit from services that are designed to support a broad range of neurodiverse students, or services that are …

Whose Expertise Is It? Evidence For Autistic Adults As Critical Autism Experts, Kristen Gillespie-Lynch, Steven K. Kapp, Patricia J. Brooks, Jonathan Pickens, Ben Schwartzman

Publications and Research

Autistic and non-autistic adults’ agreement with scientific knowledge about autism, how they define autism, and their endorsement of stigmatizing conceptions of autism has not previously been examined. Using an online survey, we assessed autism knowledge and stigma among 636 adults with varied relationships to autism, including autistic people and nuclear family members. Autistic participants exhibited more scientifically based knowledge than others. They were more likely to describe autism experientially or as a neutral difference, and more often opposed the medical model. Autistic participants and family members reported lower stigma. Greater endorsement of the importance of normalizing autistic people was associated …

Negotiating And Navigating Invisible Food Deserts: An Exploratory Study On Foodways Of Adults On The Autism Spectrum, Jungja Park Cardoso

Dissertations, Theses, and Capstone Projects

I explored foodways of adults on the autism spectrum in order to understand how they negotiate and navigate their food environments. Foodways are beliefs and practices involved in food production, preparation, distribution and consumption (Counihan 2008). In an effort to hear marginalized voices in autism discourse, I conducted an online survey and interviews in modes chosen by participants to accommodate the communication needs of a wide range of autistic adults. The primary participants were highly educated adults with a formal autism diagnosis (n = 23) and self-diagnosed adults (n = 6). Out of the 29 autistic participants who …

A Developmental Perspective On Parental Cognitions And Emotions In The Context Of A Parent-Mediated Intervention For Children With Asd, Emily R. Hotez

Dissertations, Theses, and Capstone Projects

Previous research demonstrates that parenting-related schemas and perceptions, reflective functioning abilities, and emotional experiences (i.e., parental cognitions and emotions) play a pivotal role in predicting whether parents of children with Autism Spectrum Disorder (ASD) are actively involved in, and demonstrate capacity in, meeting their child’s needs in the context of intervention programs or services related to their child’s development. In light of these findings, researchers have focused increased attention towards investigating whether parent-mediated interventions that target children’s behaviors and developmental outcomes exert collateral effects on parental cognitions and emotions.

The current dissertation investigated a sample of 70 mothers of …

Targeting Efficiency: The Effects Of Video Modeling And Feedback On Instructors’ Acquisition And Generalization Of Behavior Analytic Skills, Maya S. Madzharova

Dissertations, Theses, and Capstone Projects

Applied behavior analysis (ABA) is a highly effective, evidence-based treatment for individuals with autism spectrum disorder. Low treatment integrity could greatly compromise the delivery of effective ABA interventions, but instructors who hold no formal training make up the larger portion of employees within the special education field. Designing efficient and effective training for these employees is important because schools have limited resources for caregiver training. This study used a non-concurrent multiple baseline design across three novice ABA instructors to evaluate the effects of a training protocol consisting of video and in-vivo modeling and feedback, a training algorithm, and multiple exemplars …

Repetitive Motor Movement, Social Responsiveness, And Global Development In Children With Autism Spectrum Disorder, Jenny Waltzer

Theses and Dissertations

This study assessed whether specific repetitive motor movements (involving body), are associated with social abilities and global development. Additionally, we evaluated whether our observational measures of specific repetitive behaviors corresponded to standard diagnostic measures. Sixty-nine children, aged 32 to 82 months, with a diagnosis of autism spectrum disorder or autism were enrolled.

Biological Motion Processing In Typical Development And In The Autism Spectrum, Aaron Krakowski

Dissertations, Theses, and Capstone Projects

Biological motion (BM) analysis and interpretation is a fundamental process of human neurocognition that has been only minimally explored neurophysiologically. In addition to its importance in understanding the underlying roots and development of social cognition, BM processing is a prime candidate domain for exploring the underlying etiology of social cognitive disorders such as the autism spectrum.

In an initial experiment, typical adults observed BM point-light displays of a human actor (UM) as well as their spatially scrambled counterparts (SM), in both an unattended distractor task as well as an explicit attention task. Results showed a neurophysiological response manifested as three …

Exploring The Role Of Perceived Religiosity On Daily Life, Coping, And Parenting For Jewish Parents Of Children With Autism, Frances Rebecca Victory

Dissertations, Theses, and Capstone Projects

This two-part study (a) explores the multi-dimensional aspects of religious and psychosocial experience of Jewish mothers and fathers with and without a child with autism; and (b) uses a multi-method design to examine the influence of perceived religious beliefs, ritual practices, and community context on daily life, parenting, and coping processes for these parents. The first study included 20 fathers and 34 mothers of typically developing children. Participants were affiliated with Reform, Conservative, and Modern Orthodox Judaism. They completed three online q-sorts and five open-ended questions. The three q-sorts focused on the perceptions of religious beliefs, ritual practices, and community …

The Neurodevelopment Of Basic Sensory Processing And Integration In Autism Spectrum Disorder, Alice Brown Brandwein

Dissertations, Theses, and Capstone Projects

This thesis presents three studies that together explore the neurophysiological basis for the sensory processing and integration abnormalities that have been observed in autism spectrum disorder (ASD) since the disorder was first described over half a century ago. In designing these studies we seek to fill a hole that currently exists in the research community‟s knowledge of the neurodevelopment of basic multisensory integration -- both in children with autism and as well as in those with typical development. The first study applied event related potentials (ERPs) and behavioral measures of multisensory integration to a large group of healthy participants ranging …
