The Effects Of Calmer On The Quality Of Life In Adults With Level 1 Autism Spectrum Disorder, Madilyn Morris

Honors Theses

Level 1 autism spectrum disorder (ASD) is a high-functioning neurodevelopmental disorder (Hodges et al., 2020; Hosseini & Molla, 2023). Several features of level 1 ASD negatively impact quality of life (QOL), and auditory sensitivity (specifically hyperacusis) is one of the most prevalent and disabling features (Danesh et al., 2015, 2021; Kuiper et al., 2019; Williams et al., 2021). Hyperacusis significantly impacts QOL in the level 1 ASD population, as current hyperacusis treatment strategies often result in various forms of social isolation (Adams et al., 2021; Danesh et al., 2015; Neave-DiToro et al., 2021).

The Effect Of Microglial Cell Dysfunction On Multi-Modal Pre-Pulse Inhibition, Michelle Besser

Dissertations, 2020-current

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication, restricted behaviors, and executive functioning deficits. Mutations in fractalkine signaling, particularly in CX3CR1, in the brain have been linked to ASD and other neurodevelopmental disorders. This investigation examined wild-type mice and mice with one or two copies of mutated CX3CR1 and their uni-modal (auditory and somatosensory) and multi-modal (combined) pre-pulse inhibitions (PPI). PPI is an unconditioned response – a decrement in the acoustic startle reflex when the mouse detects a non-startling stimulus presented a few hundred ms before the startling sound. In this study, the …

The Role Of The Pcc And Acc In Autism Spectrum Disorder: A Functional Connectivity Study, Claudia Gonzalez

Honors Theses

Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that impacts behavior control and social skills. Currently, ASD diagnoses are largely qualitative; thus, having more quantitative means of identification would aid in earlier diagnosis of ASD. However, more research is needed to pinpoint observable neurobiological markers of ASD. Our study focused on the posterior cingulate cortex (PCC) due to past evidence suggesting its involvement in ASD symptomatology. The PCC has been linked to behavioral control and executive functioning. Moreover, previous studies support executive functioning’s responsibility for the repetitive and restricted behaviors (RRB) in ASD.

Method: Our study sought to …

Identifying Key Language Research Priorities In Autistic Children According To Parents, Taylor Hale

LSU Master's Theses

The lack of involvement of the autistic community and its stakeholders in autism research has led to a call to action. At present, autism researchers have limited knowledge about stakeholders’ priorities for research. The current study aimed to bridge the disconnect between the extant autism research and the recent neurodiversity movement by surveying key stakeholders – parents of autistic children – on their perspectives on autism research that focuses on language. Twenty-six parents of autistic children completed an online survey on their views on autism language research with an option to participate in a follow-up interview. Six parents participated in …

Our Voices: Getting To Know Autism, Katherine Rasberry

Honors Theses

This study was done in effort to understand the thoughts and feelings of autistic adults relative to life transitions and resources available. We surveyed key stakeholders; specifically autistic students, but also family/caregivers of adults. Six surveys were created, each based upon different themes: camouflaging, life transitions, managing mental health, overstimulation, social communication, and family and caregiver perceptions. Our surveys were marketed on Western Michigan University’s campus and through social media and are still ongoing. Trends in the data, however, suggest that overall autistics have concerns about how their disabilities impact life in or shortly after college. Many respondents expressed they …

Paths To Equity: Parents In Partnership With Ucedds Fostering Black Family Advocacy For Children On The Autism Spectrum, Elizabeth H. Morgan, Benita D. Shaw, Ida Winters, Chiffon King, Jazmin Burns, Aubyn Stahmer, Gail Chodron

Developmental Disabilities Network Journal

Racism and ableism have doubly affected Black families of children with developmental disabilities in their interactions with disability systems of supports and services (e.g., early intervention, mental health, education, medical systems). On average, Black autistic children are diagnosed three years later and are up to three times more likely to be misdiagnosed than their non-Hispanic White peers. Qualitative research provides evidence that systemic oppression, often attributed to intersectionality, can cause circumstances where Black disabled youth are doubly marginalized by policy and practice that perpetuates inequality. School discipline policies that criminalize Black students and inadequate medical assessments that improperly support Black …

The Urgent Need For Neuroscience Research To Consider Culture When Assessing The Development Of Gait In Autistic Children: A Scoping Review, Milijana Buac, Gabriela Ibarra, Ricardo Torres, Sinana Onal, Allison Gladfelter, Ziteng Wang

CISLL Publications

Background: Over the last decade, there has been a steady increase in the number of children diagnosed with autism spectrum disorder (ASD) on a global scale, impacting all racial and cultural groups. This increase in the diagnostic rate has prompted investigation into a myriad of factors that may serve as early signs of ASD. One of these factors includes the biomechanics of gait, or the manner of walking. Although ASD is a spectrum, many autistic children experience differences in gross motor function, including gait. It has been documented that gait is also impacted by racial and cultural background. Given that …

Age-Related Differences In Accelerometer-Assessed Physical Activity And Sleep Parameters Among Children And Adolescents With And Without Autism Spectrum Disorder: A Meta-Analysis, Xiao Liang, Justin A. Haegele, Sean Healy, Andy Choi-Yeung Tse, Hui Qiu, Shi Zhao, Chunxiao Li

Human Movement Studies & Special Education Faculty Publications

Importance: Physical inactivity and sleep disorders are health-related concerns of youth with autism spectrum disorder (ASD) that can persist from childhood and exacerbate core symptoms. However, evidence on group differences in accelerometer-assessed physical activity and sleep parameters among youth with and without ASD is inconclusive and age-specific effects remain unclear.

Objective: To synthesize evidence on group differences in accelerometer-assessed physical activity and sleep parameters and examine the moderating effects of age between children and adolescents with and without ASD.

Wayne State University Dissertations

EVALUATION OF TELE-DIAGNOSTIC PRACTICES IN AUTISM SPECTRUM DISORDER By Emily Graham LeRose Advisor: Dr. Shelly Jo Kraft, PhD, CCC-SLP Major: Communication Sciences and Disorders Degree: Doctor of Philosophy

Following the social-distancing mandates of the COVID-19 pandemic of 2020, diagnosis of autism spectrum disorder pivoted from an in-person method of evaluation, utilizing empirically supported “gold-standard” methods, to novel tele-diagnostic methods. This research investigated the efficacy and accessibility of autism diagnostic services using the tele-diagnostic platform of autism assessment by comparing retrospective patient data from periods of in-person assessment to tele-diagnostic assessment at one, large, urban hospital.

Diagnostic outcomes for these two …

Improving Diagnostic Outcomes For Individuals With Autism Spectrum Disorders Within The Hispanic Community In Bowling Green, Kentucky, Bethany Waddey

Mahurin Honors College Capstone Experience/Thesis Projects

Despite the importance of early identification and intervention of autism spectrum disorder (ASD), Hispanic children are significantly under-diagnosed with ASD in comparison to non-Hispanic, white children due to barriers to ASD identification in this population. The purpose of this research is to determine the levels of ASD knowledge in the Hispanic community in Bowling Green, the barriers that may contribute to why ASD is underdiagnosed in Hispanic children, and how to mitigate these barriers. This research analyzes the results of a survey, called the “Autism Spectrum Knowledge Scale- General Population Version”, administered to 51 participants from the Hispanic population of …

Similar Overall Expression, But Different Profiles, Of Autistic Traits, Sensory Processing, And Mental Health Between Young Adult Males And Females, Garrett Cardon

Faculty Publications

Recent trends suggest that autism is more common in females than traditionally held. Additionally, some argue that females express autistic traits differently than males. Dimensional views of autism could shed light on these issues, especially with regards to understudied behavioral areas, such as sensory processing. We examined autistic traits, sensory processing, anxiety, and related behaviors in a large sample of neurotypical young adult males and females (n = 1122; 556 female; ages 19–26). Participants completed an online survey containing questionnaires related to the above. Between groups statistical analyses, as well as within groups correlations and mediation analyses containing these constructs …

Let's Count The Ways We Can Utilize Technology To Improve Instructional Practices For Individuals With Autism, Heather Coleman, Annemarie L. Horn, Selena J. Layden, Christian Coogle

Human Movement Studies & Special Education Faculty Publications

To maximize instruction and learning outcomes, it is essential that educators and family members who support individuals with autism have adequate training and support required to implement evidence-based practices (EBPs) with fidelity. Research shows various coaching methods, including self-coaching and classroom-based feedback, yield positive outcomes in terms of increasing practical application and sustained use of EBPs. With the growing prevalence of autism, it is essential to find effective coaching methods that can be utilized equitably across geographic locations and learning environments. Fortunately, technology affords educators and others the opportunity to receive quality coaching and feedback without facing traditional barriers (e.g., …

Comparison Of Machine Learning Methods For Classification Of Alexithymia In Individuals With And Without Autism From Eye-Tracking Data, Furkan Iigin, Megan A. Witherow, Khan M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Alexithymia describes a psychological state where individuals struggle with feeling and expressing their emotions. Individuals with alexithymia may also have a more difficult time understanding the emotions of others and may express atypical attention to the eyes when recognizing emotions. This is known to affect individuals with Autism Spectrum Disorder (ASD) differently than neurotypical (NT) individuals. Using a public data set of eye-tracking data from seventy individuals with and without autism who have been assessed for alexithymia, we train multiple traditional machine learning models for alexithymia classification including support vector machines, logistic regression, decision trees, random forest, and multilayer perceptron. …

Uncertainty, Sensory Processing, And Stress In Autistic Children During The Covid-19 Pandemic, Garrett Cardon, Mollie Bradley

Faculty Publications

Background: COVID-19 increased uncertainty for most and was especially disruptive to autistic people and their families, due in part to tendencies toward intolerance for uncertainty across this population. As such, COVID presented a natural experiment of uncertainty and its correlates in autism. Previous reports have shown associations between intolerance of uncertainty, sensory difficulty, and stress. Aims: We investigated changes in sensory difficulties and stress associated with COVID-related increases in uncertainty. Methods and procedures: Primary caregivers of 47 autistic children (ages 6–15) completed online surveys containing questions about demographics, experiences, and supports received during the pandemic. Additionally, caregivers filled out measures …

Implications For Cross-Training Between Applied Behavior Analysis And Speech-Language Pathology, Katherine Lynn Isaacson

Speech and Hearing Sciences Publications

This paper is to provide clarity about the overlaps between the fields of Applied Behavior Analysis (ABA) and speech-language pathology, including evaluation, assessment, intervention planning, and treatment of language development, nine articles were selected for a review of terms and definitions, philosophical and theoretical underpinnings, and licensure/certification requirements pertaining to both scopes of practice. Behavior analysts and speech-language pathologists (SLPs) are likely to provide intervention alongside one another due to their frequent provision of intervention with individuals diagnosed with autism spectrum disorder (ASD). Despite broad, initial overlaps between the professions, the required educational coursework, supervised fieldwork and clinical practicums, and …

Intolerance Of Uncertainty, Sensory Processing, And Related Correlates In Autistic Children During The Covid-19 Pandemic, Mollie Bradley

Theses and Dissertations

The COVID-19 pandemic increased uncertainty and anxiety for most and was especially disruptive to autistic people and their families. Autistic children were particularly vulnerable due to their intolerance for increased uncertainty and disruption to their school and therapy support. This study aimed to investigate the effect that increased uncertainty had on autistic children, specifically their sensory behaviors and stress levels and on the stress levels of their primary caregivers. Parents and guardians of 47 autistic children completed an online survey consisting of questions investigating background and demographic information, their experiences during the first six months of the pandemic, information about …

Dynamic Measures Of Referential Communication Reveal Hidden Pragmatic Strengths For Adolescents With Autism Spectrum Disorder, Mariana Schreuders

Senior Honors Projects, 2020-current

The ability to communicate effectively and efficiently while maintaining mutual understanding is a fundamental aspect of human-to-human interaction. Studies have shown that individuals with autism spectrum disorder (ASD) face challenges in areas of social communication skills, such as aspects of referential communication; or the ability to refer to things in such a way that a listener will know what the speaker is describing. The current study used data from a preexisting Barrier study to compare the referential communication abilities of school-aged children with ASD to those of neurotypical children (NT). Referential communication was observed during a barrier task, where participants …

Pre-Pulse Inhibition In Mutated Mice: Studying Compromised Microglial Cells To Discover New Genetic Connections To Autism, Bailey R. Kramarik

Senior Honors Projects, 2020-current

Microglial cells “play a pivotal role in refining neural networks during early critical periods” (Gabriele & Gray, 2020, p. 1). A disturbance in the functioning of these microglial cells contribute to specific characteristics of some neurodevelopmental disorders- including autism spectrum disorder. In this study, we used a mouse model to study disruptions in cell activity, as understanding the biological and genetic background of autism spectrum disorder could help us provide better treatment and therapy options to those diagnosed.

The mutated mice in this experiment have microglial cells with “compromised fractalkine signaling” (Gabriele & Gray, 2020, p. 4-5). We studied multimodal …

The Impact Of Distance Education On Therapy Services For Students With Asd: An Slp Perspective, Andrea Spragg

Dissertations, Theses, and Projects

The coronavirus disease of 2019 (COVID-19) pandemic caused an abrupt change in the day-to-day lives of individuals across the world as adults were forced to work from home and children were forced into virtual school environments. For all students, this disruption in schedule and daily routine been hard, but especially those with autism spectrum disorder (ASD) (Mumbardo-Adam et al., 2021). For many students with ASD, school is a place in which they receive many essential services and social interactions, such as speech therapy, that they may not receive other places. The purpose of this survey research was to understand the …

Measuring Referential Communication Dynamically In Older Children With Asd, Caitlin Lee

Masters Theses, 2020-current

Research finds individuals with autism spectrum disorder (ASD) are relatively ineffective and/or inefficient at referential communication. However, this research typically uses static metrics of efficacy (how accurately messages were relayed) and efficiency (overall word count), rather than dynamic ones (e.g., Does the speaker alter subsequent descriptions when the listener previously misunderstood them?). The aim of this research is to use dynamic measures of efficacy and efficiency to examine how speakers with and without ASD adjust their message to meet listener needs across time. Fifteen older children with (n = 8) and without (n = 7) ASD were included. …

Like, It’S Important: The Frequency And Use Of Like In Autism Spectrum Disorder, Rebekah Jones

Masters Theses, 2020-current

Background & Aims: Discourse markers, such as well or like serve a variety of functions to support conversational reciprocity: filling pauses, aiding word-finding, holding conversational turns, and providing information about pause length. Previous research shows that individuals with ASD use discourse markers less frequently than neurotypical (NT) peers; however, the discourse marker like has been left out of that research, despite its ubiquitous use by NT individuals, and despite the fact that like serves important pragmatic functions that are not encoded by any other discourse marker. Specifically, like signals to the listener that the content of upcoming speech is 1) …

Responses To Partner Comments And Acknowledgements In Students With And Without Autism, Kaitlyn Bresette

Masters Theses, 2020-current

Some children and adolescents with Autism Spectrum Disorder (ASD) initiate and respond less frequently than neurotypicals (NT) during language sampling tasks. More information is needed regarding how partner behaviors, such as comments and acknowledgements and the sampling context, influence the types of responses provided by children with ASD. This research study examined responses to adult comments and acknowledgments in two language sampling tasks, a traditional Share and Tell sample and a Double Interview sample (Garcia-Winner, 2002).

Participants. Fifty-eight participants, between the ages of 10 and 17 years, were recruited across two labs. The sample consisted of 28 adolescents with ASD …

The Influence Of Improv Experience On Uncertainty Tolerance, Social Anxiety, And Communication In Adolescents On The Autism Spectrum, Kathryn K. Desbiens

Undergraduate Honors Thesis Collection

This study examined the influence of an improvisational theater experience on perceptions of social anxiety, intolerance of uncertainty (IU), and quality of communication life in autistic adolescents. Seven participants were recruited from Indiana University’s Camp Yes And, a virtual day camp specializing in teaching improv strategies to autistic adolescents. Participants completed three scales measuring social anxiety, IU, and quality of communication life via surveys sent prior to and after attending the camp. It was hypothesized that levels of social anxiety and IU would decrease while quality of communication life would increase. Results indicated that pre- and post-test survey responses showed …

Predicting Autism From Infant Characteristics: A Systematic Review, Alysha Y. Henrichs, Cynthia Cress Ph.D.

Honors Program: Senior Projects (Public)

A literature review was conducted of 73 articles to explore 12-month-old characteristics in infants that predicted later diagnosis with autism (ASD). Articles were reviewed if they discussed ASD, infants with siblings diagnosed with autism (high-risk) and/or infants later diagnosed with autism without known family history of ASD (low risk). Articles were not reviewed if the participants were 36 months or older at the start of the study. More factors were identified that discriminate characteristics associated with later ASD diagnosis in infants between 12-24 months compared to characteristics of infants below 12 months. Characteristics of infants under 12 months that were …

Aac Use By Children With Asd And Their Aac Co-Pilots, Kelcy Rolak

Master's Theses and Doctoral Dissertations

Employing a multiple case study approach, this study explored the perspectives of parents of children with autism spectrum disorder (ASD) on their child’s use of augmentative and alternative communication (AAC). Deemed “AAC co-pilots” by this study, these parents play a crucial role in their children’s daily AAC use, yet their perspective is largely under-explored in existing research that otherwise explores AAC use by individuals with ASD extensively. Semi-structured interviews were conducted with parents of children with ASD who have used AAC for at least one year and whose AAC use is documented in their IEP. Findings indicated the depth and …

Profiles And Correlates Of Language And Social Communication Differences Among Young Autistic Children, Rachel Reetzke, Vini Singh, Ji Su Hong, Calliope B. Holingue, Luther G. Kalb, Natasha N. Ludwig, Deepa Menon, Danika L. Pfeiffer, Rebecca J. Landa

Communication Disorders & Special Education Faculty Publications

Delays in early language development are characteristic of young autistic children, and one of the most recognizable first concerns that motivate parents to seek a diagnostic evaluation for their child. Although early language abilities are one of the strongest predictors of long-term outcomes, there is still much to be understood about the role of language impairment in the heterogeneous phenotypic presentation of autism. Using a personcentered, Latent Profile Analysis, we first aimed to identify distinct patterns of language and social communication ability in a clinic-based sample of 498 autistic children, ranging in age from 18 to 60 months (M = …

Stimming Expresses Empathy, Not To Be Masked Or Persecuted: A Scoping Review And Case Study Of The “Double-Empathy Problem” Solved By Recognizing The Autism Language, Kathryn Haas

Student Capstone Papers

This article critically examines autism and autistic stimming through the lenses of neurotypicals and autistics, evaluates confines currently imposed upon autistics by neurotypical society, and synthesizes what autistic leaders have expressed about their experiences striving for inclusion (Gernsbacher, 2017; Milton, 2012). Autistic-led studies are now at the forefront of the neurodiversity movement and are growing in fervor. The following themes were identified: (a) prevalence of autism, (b) the interpretation and measurement of empathy, (c) discovery of genetic factors transformed autistics’ identity, (d) publication of non-genetic factors such as vaccines undermined the legitimacy of the autism language, (e) the problem with …

Tinnitus Effects And Correlations Between Capd, Language Processing, And Asd: A Capstone Case Series, Kristin Williford, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

Introduction: Some people with tinnitus have normal audiometric hearing thresholds. Even when hearing is within normal limits, patients can suffer a myriad of symptoms from tinnitus, including depression and other mental health problems. Case Presentation: A male adult presented to the clinic with complaints of bothersome tinnitus, asymmetric hearing loss, and a long history of environmental noise exposure, including both occupational and recreational noise. Discussion: Audiologists should determine the primary concerns of their tinnitus patients and how the condition affects their health and wellbeing. To do this, a thorough case history, audiologic assessment, outcome measures, and empathetic listening should be …
