Toilet Training And Teaching Self-Initiations To Children With Autism Who Use Augmentative And Alternative Communication, Darcy A. Douglass

Honors Capstones

Within this project, we address the challenges faced by individuals, particularly those with autism spectrum disorder (ASD), during toilet training, which often takes longer than neurotypical children. Practitioners who use traditional methods often overlook teaching children how to request bathroom use, especially among those who use augmentative and alternative communication (AAC) devices. Drawing from literature and expert recommendations, we summarize the importance of teaching independence in bathroom use for children with complex communication needs by incorporating their AAC devices when teaching toilet training.

Inspired by Perez et al. (2020), who demonstrated positive responses from individuals with ASD to reinforcement-based procedures, …

Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris

Master's Theses

The language development and usage of autistic individuals has become a controversial topic in many of the disciplines and professions providing support to these individuals. As a result, two theories of language processing have been proposed. Analytical language processing suggests that children process and develop language from its most simple form, a phoneme, to its most complex form, a word or phrase. However, the theory of gestalt language processing proposes that some children may instead extract larger, more complex language such as whole words and phrases first and break it down to the simpler language. Gestalt language processing is often …

Utilizing Special Interests: Developing A Storybook For A Minimally Speaking Autistic Child To Support Communication, Olivia Fordyce

Honors Projects

The purpose of my Honors Project is to develop a framework for designing a storybook that can be used as a communication tool with minimally speaking autistic children. The project answers two clinically relevant questions within the field of Speech-Language Pathology.

1. What do we know from prior literature about the use of storybooks to support communication in minimally speaking autistic children?
2. What factors are important to consider in designing a storybook for minimally speaking autistic children?

I conducted a literature review exploring adapted storybooks and autistic children’s special interests to answer the project questions. Informed by this knowledge, I have …

Honors Theses

The meta-analysis examines scholarly articles regarding research on evidence-based communication for students with Autism Spectrum Disorder. More specifically, this research involves different forms of Alternative and Augmentative Communication. This form of communication is used without a voice. A variety of interventions for Manual Signing (MS), Speech Generating Devices (SGD), and Picture Exchange Communication Systems (PECS) are reviewed within the research study. The purpose of this research is to define which evidence-based Alternative and Augmentative Communication (AAC) interventions are most effective for children with Autism. More specifically, determining which form of communication can help lead children to more expressive language and …

Telepractice-Based Language Intervention Training For Parents Of Children With Autism Spectrum Disorders, Sarah Bryan

Honors Theses

This study closely examined the progression and fidelity of strategy implementation of parents undergoing an ASD language intervention training program. This instructional, interactive program was designed for parents of children with autism, thus catering to the needs of participants involved. This study assessed the use of parent comments and redirects, two kinds of parent strategies, during each parent-child interaction to provide more information about the impact of training sessions. The researchers hypothesized that by the end of training, parent participants would increase their fidelity of strategy implementation, increase their use of comments rather than redirects, and employ more open-ended questions …

The Relationship Between Social Cognition And Social Behavior Of Young Adults With Autism Spectrum Disorder Using The Ucla Peers® For Young Adults Social Skill Program, Meaghan Balsdon

Electronic Theses and Dissertations

Research indicates that social communication impairments are a defining and persistent feature of Autism Spectrum Disorder (ASD; Centers for Disease Control and Prevention, 2022). Social communication consists of what an individual knows about social skills (i.e., social cognition) and how they observably respond in social situations (i.e., social behavior). It is difficult to gain a comprehensive assessment of social communication because social cognition assessments are prone to inaccuracies due to poor metacognitive skills in individuals with ASD (DeBrabander et al., 2021; Cederlund et al., 2010; Vickerstaff et al., 2006). Inaccurate reporting of social cognition leads to potential discrepancies in observable …

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 …

The Efficacy Of A Telepractice Service Delivery Model For Providing Speech And Language Services To Children With Asd, Myranda L. Marotta

Masters Theses

The impact of the COVID-19 pandemic required the use of remote technologies for society and the workforce to function under quarantine conditions. The literature on telepractice services for individuals with ASD has proliferated during the past decade, especially during the past two years. Still, many publications on the topic lack scientific merit. This study utilized a quasi-experimental, single-subject, multiple-group, time-series design to investigate whether telepractice SLP services are at least as effective as the traditional, face-to-face delivery model.

Twenty-one students with autism spectrum disorder were included in this study. Additionally, 22 speech-language pathology graduate students and four SLP school professionals …

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 …

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 …

Verbal Fluency In Women With The Fmr1 Premutation And The Broad Autism Phenotype, Emily Szabo

Theses and Dissertations

Women who carry a premutation allele on the FMR1 gene can experience limitations due to their genetic status, including executive function deficits. These subtle deficits are often shared by women who possess the broad autism phenotype (BAP). Poor understanding and limited research on the extent of these executive functioning deficits has led to limited clinical management of these two groups. The current study aimed to clarity whether there is a difference in verbal fluency abilities in mothers that possess the FMR1 premutation, mothers of children with autism who are at risk for the BAP, and mothers of typically developing children, …

Characterizing Receptive Vocabulary Knowledge In Minimally Verbal Children With Autism Spectrum Disorder, Allison Menting

LSU Master's Theses

Background: Delayed or impaired language skills are common characteristics of children with autism spectrum disorder (ASD). Currently, there is little research examining the receptive language profile in children with ASD, and even less is known about children with ASD who are minimally verbal. The current study aimed to characterize the receptive vocabulary profile of minimally verbal children with ASD and to examine whether this profile differs from their typically developing peers. Methods: Participants included 31 minimally verbal children with ASD, aged 60-118 months, who were reported to produce between 0-10 words, 124 typical developing toddlers, aged 9-14 months, who were …

Functional Connectivity Of The Inferior Frontal Gyrus In Autism Spectrum Disorders, Emma Miller

Honors Theses

ABSTRACT

The American Speech-Language-Hearing Association defines Autism Spectrum Disorder (ASD) as a “neurodevelopmental disorder characterized by deficits in social communication and social interaction” which is heavily impacts language abilities. There is an abundance of research on the neurological aspects of the disorder, which appear to have major differences of activation and functionality when compared to typically developing peers. Specifically, in the left inferior frontal gyrus (IFG), a key language region of the brain, functional connectivity levels tend to be significantly less in ASD groups. This study recognizes these trends and aims to expand the research by locating specific functional connections …

A Systematic Review Of The Literature On The Assessments Used For Social Communication In The Diagnosis Of Autism Spectrum Disorder, Rachel E. Kim

Masters Theses

This review of the literature aims to analyze the current assessments available for clinicians, parents, and other professionals to use during the diagnosis of Autism Spectrum Disorder (ASD) that specifically addresses social communication. Although ASD can be diagnosed as early as the age of 2, children are often not diagnosed until the age of 4-5 years old. Especially for children who would be diagnosed with ASD and require Level 2 and/or Level 3 supports, early diagnosis can lead to early intervention which can help to provide the necessary support for both the child and family. Early intervention can help to …

Speech-Language Pathology Interventions And Ingredients That Support Social Communication And Language Of Preschoolers With Autism, Amanda Binns

Electronic Thesis and Dissertation Repository

One of the best predictors of long-term outcomes for autistic children is development of language and social communication skills. Therefore, it’s not surprising that speech and language therapy is one of the most frequently accessed interventions for children with suspected or diagnosed autism. From a public health and family well-being perspective, identifying effective social communication interventions and better understanding the specific components that contribute to their effectiveness is critical. However, there is a lack of clarity about the most effective interventions. This dissertation addressed this important topic through three studies.

Study 1 examined the literature on interventions provided by speech-language …

Parent/ Caregiver Burnout With Autism Due To Covid, Leah Recker, Erin Babcock

Williams Honors College, Honors Research Projects

The purpose of this project is to gain an understanding how parents of children with autism are affected by caregiver burnout. We want to understand the different factors that contribute to this burnout and analyze how individuals are affected differently. To do this, we are sending

out a survey using Likert scale items to assess parents’ stress and burnout. We will be carefully selecting statements based off information we gather through peer reviewed journal articles. We would then like the parents to decide how strongly they agree or disagree with each question. This will create a more in-depth picture of …

An Eye Tracking Investigation Of The Pragmatic Language Comprehension Abilities Of Children With Autism, Kristina Curro

Doctoral Dissertations

Autism is a disorder of the comprehension and use of pragmatic language. Children with autism often display heterogeneous patterns of language ability even when language is considered a strength. This real-time analysis is a partial replication of Sedivy et al. (1999) who found evidence for incremental processing of pragmatic language in real-time with adults. This investigation focused on prosodic focus and scalar adjective comprehension in children with and without autism. Results show that children with autism successfully interpret prosodic focus when interpreting intersective adjectives but show processing delays in interpreting scalar adjectives. Implications for pragmatic language processing differences between children …

Visual Perspective Taking In Autism Spectrum Disorders, Erin L. Reilly

Dissertations, Theses, and Capstone Projects

Individuals with autism spectrum disorders (ASD) have difficulty in recognizing environmental perspectives other than their own. Perspective-taking deficits impact language use and understanding in discourse and more general social and cognitive function. Despite extensive research on perspective taking abilities in individuals with ASD, many factors have not been fully examined. This study further examined the contribution of angular disparity, anthropomorphism of an observer, and language use on visual perspective-taking.

Individuals with (ASD) demonstrate a strength in visual spatial cognition and a weakness in visual social cognition. This study examined the factors that may cause people with ASD to have difficulties …

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 …

Wernicke’S Area In Autism: Rsfmri Study, Sydney Osbarn

Honors Theses

We investigated the functional connectivity of Wernicke’s Area and its right homologue (Planum Temporale) in individuals with Autism Spectrum Disorder (ASD) and typically developing individuals. We used resting state functional magnetic resonance imaging to analyze these areas in 145 participants from The University of Michigan via ABIDE. As a retest sample, we also used data from a University of Pittsburgh cohort. There is weakened functional connectivity between Wernicke’s Area and Planum Temporale in individuals with ASD as opposed to typically developing individuals. Participants with ASD did not have greater connectivity in other regions compared to the control group. Pragmatics, nonverbalism, …

Acoustic And Perceptual Characteristics Of Prosody In Autism Spectrum Disorder: The Impact Of Language, Motor Speech, And Auditory Processing, Colleen Gargan

Doctoral Dissertations

Autism Spectrum Disorder (ASD) is a lifelong neurodevelopmental condition that affects an individual’s social communication, social interaction, and behavior (American Psychological Association, 2013). A striking feature that distinguishes some individuals with autism from their peers without autism is “atypical” prosody. A between-group study was conducted to investigate prosody, speech motor control, auditory processing of pitch, and trained listener ratings of prosodic “naturalness” among adolescents with ASD (n=17) compared to TD controls (n=17) matched for age, gender and language. The specific aims of this study were to: (1) determine if individuals with ASD have significant acoustic-perceptual differences in their receptive and …

Social Conformity And The Line Judgement Task For Adolescents With Asd, Jamie Mcclendon

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The primary intent of this study is to add to the growing research regarding social functioning and theory of mind (ToM) of young adults with autism spectrum disorder (ASD). This study takes into account the Solomon Asch line judgement tasks effect on peer pressure and social conformity. Previous research has shown that there is a discrepancy in the conformity exhibited by typically developing individuals (TD) and ASD individuals. This study seeks to address the degree to which ASD individuals are affected by social influence and how likely they will be to conform. Conformity rates will be compared to that of …
