Trends And Barriers In Service Utilization In Underrepresented Ethnoracial Groupswith Autism Spectrum Disorder In The United States: A Mixed-Method Analysis, Sadaf Khawar

Theses, Dissertations and Culminating Projects

Caregivers with autistic children, particularly from minoritized populations, experience significant barriers while navigating the complex healthcare system, including acquiring services. Therefore, it is crucial to understand what these barriers are in order to inform policymaking initiatives to support families. Notably, there is a significant gap in extant literature to explore trends in service use and unique experiences of caregivers of autistic youth from three historically underrepresented groups in research (and currently not in the parameters of the United States census): 1) South Asian, 2) Middle Eastern and North African (MENA), and 3) East African. This study employed a mixed-method design …


Vulnerability Of Semantic Networks In Multiple Sclerosis: An Analysis Of Verbal Fluency Data, Sophia Lall May 2024

Vulnerability Of Semantic Networks In Multiple Sclerosis: An Analysis Of Verbal Fluency Data, Sophia Lall

Theses, Dissertations and Culminating Projects

Word finding difficulty is a frequently reported subjective cognitive concern among persons with Multiple Sclerosis (pwMS). Word-finding relies on several information retrieval processes, including search and retrieval from the conceptual store, the phonological store, the syllabary, as well as other stores of information. Neuropsychological assessments, including the semantic verbal fluency measure, can be used to measure word retrieval abilities. Despite this, the MS research literature shows that neuropsychological assessment of semantic verbal fluency yields mixed results in detecting word-finding difficulties. While some studies report finding statistically lower semantic fluency scores in pwMS relative to healthy controls (HC), others found no …


Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher May 2024

Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher

Master's Theses

Drastic declines in recess physical activity (PA) have been observed within recent years (Center for Disease Control (CDC), 2017). Due to recess’ discretionary nature, psychosocial variables associated with PA are predictors of students’ PA levels. Recess is also a time of heightened bullying occurrences (Vaillancourt et al., 2010). Appearance-based bullying is the most common type of victimization that occurs in schools, transpiring more often in children with larger body max indexes (BMI), and possibly altering students’ physical self-perceptions. Physical self-perceptions have been shown to impact PA motivation, however, it is still unknown the extent to which appearance-based bullying, body size, …


A Mixed Methods Exploration Of Interoceptive Awareness In Adults Who Stutter, Hazel Malcolm May 2024

A Mixed Methods Exploration Of Interoceptive Awareness In Adults Who Stutter, Hazel Malcolm

Graduate Theses and Dissertations

Stuttering is commonly described as a disorder of speech fluency characterized by primary speech behaviors that are judged by external observers to be typical of stuttering, including part-word repetitions, prolongations, and blocks (i.e., silent prolongations or postural fixations). Despite wide use in the field of speech-pathology, definitions focusing on these ‘primary’ behaviors have also been criticized as ‘surface’ or ‘perceptual’ definitions that favor the experience of a listener over that of the speaker. Recent qualitative evidence suggests that, when asked, adults who stutter (AWS) instead define stuttering as an internal feeling or awareness of being ‘stuck’ that is surrounded by …


Using Aac To Build Young Beginning Communicators’ Inclusion In Song Routines, Sydney Miller May 2024

Using Aac To Build Young Beginning Communicators’ Inclusion In Song Routines, Sydney Miller

Graduate Theses and Dissertations

The present study examined the effectiveness of augmentative and alternative communication (AAC) on preschool-aged beginning communicators’ ability to participate linguistically during song social routines. The AAC used during the intervention phase were visual scene displays (VSDs). VSDs are color-realistic photos, often depicting real people, that are context-rich for the user. VSDs are less demanding and offer the user a way to communicate their thoughts, feelings, or emotions in a more contextualized way. The present study used a multiple-baseline across participants approach. The primary dependent measure was the linguistic participation of each participant using the VSD. The results indicated that each …


Comparing Children’S Engagement In Storybook Reading With And Without Access To Aac With A Literacy Supportive Feature, Brooke Zimmerman May 2024

Comparing Children’S Engagement In Storybook Reading With And Without Access To Aac With A Literacy Supportive Feature, Brooke Zimmerman

Graduate Theses and Dissertations

Purpose: This thesis evaluates the effects of comparing children’s engagement in storybook reading with and without access to high-tech augmentative and alternative communication (AAC) with a literacy supportive feature. Literacy skills are a fundamental cornerstone for engagement in the lives of young children. Among these skills, the ability to decode words, or phonetically sound them out, plays a pivotal role in the acquisition of literacy. Proficiency in literacy also broadens the communication capabilities of individuals with developmental disabilities who rely on augmentative and alternative communication (AAC) methods. However, existing AAC technologies currently fall short in adequately strengthening literacy development, particularly …

Brain and Mind Institute

Two of every three persons living with dementia reside in low- and middle-incomecountries (LMICs). The projected increase in global dementia rates is expected toaffect LMICs disproportionately. However, the majority of global dementia care costsoccur in high-income countries (HICs), with dementia research predominantly focus-ing on HICs. This imbalance necessitates LMIC-focused research to ensure thatcharacterization of dementia accurately reflects the involvement and specificities ofdiverse populations. Development of effective preventive, diagnostic, and therapeu-tic approaches for dementia in LMICs requires targeted, personalized, and harmonizedefforts. Our article represents timely discussions at the 2022 Symposium on Demen-tia and Brain Aging in LMICs that identified the foremost …

A Cautionary Tale About Properly Vetting Datasets Used In Supervised Learning Predicting Metabolic Pathway Involvement, Erik D. Huckvale, Hunter N. B. Moseley May 2024

A Cautionary Tale About Properly Vetting Datasets Used In Supervised Learning Predicting Metabolic Pathway Involvement, Erik D. Huckvale, Hunter N. B. Moseley

Markey Cancer Center Faculty Publications

The mapping of metabolite-specific data to pathways within cellular metabolism is a major data analysis step needed for biochemical interpretation. A variety of machine learning approaches, particularly deep learning approaches, have been used to predict these metabolite-to-pathway mappings, utilizing a training dataset of known metabolite-to-pathway mappings. A few such training datasets have been derived from the Kyoto Encyclopedia of Genes and Genomes (KEGG). However, several prior published machine learning approaches utilized an erroneous KEGG-derived training dataset that used SMILES molecular representations strings (KEGG-SMILES dataset) and contained a sizable proportion (~26%) duplicate entries. The presence of so many duplicates taint the …

Supplemental High-Tech Augmentative And Alternative Communication Experiences: A Study On Graduate Student Self-Efficacy, Confidence, And Knowledge With Pre-Service Training, Emily Sikes

Master's Theses

Providing assessment and intervention with high-tech augmentative and alternative communication is within the scope of practice of American Speech-Language Pathologists (SLPS). Therefore, SLPs should be able to properly identify and implement assessment, intervention, and caregiver coaching strategies in this area of practice. Due to the lack of confidence ratings of current SLPs in providing assessment and intervention in AAC that is found in current research, this study was designed to find plausible solutions for which confidence ratings can be increased beginning at the graduate level of a Speech-Pathology Master’s program. The researchers sought to answer the following questions: “Do students …


How Speech-Language Pathologists Account For Self-Determination Across The Progression Of Dementia, Emilee Mcgahee May 2024

How Speech-Language Pathologists Account For Self-Determination Across The Progression Of Dementia, Emilee Mcgahee

Master's Theses

Dementia diagnoses are continuing to increase, with the number of diagnoses expected to reach 231 million globally by 2050 (World Alzheimer’s Report, 2019). With this comes a greater need for Speech-Language Pathologists (SLPs) who are able to best treat those who are diagnosed. Providing person-centered and strengths-based treatment approaches for people with dementia (PWD) has been proven to increase positive engagement responses while decreasing negative engagement responses (Skrainer et al., 2007). The primary objective of this research study was to assess treatment approaches used by SLPs in dementia care setting, along with how SLPs provide person-centered dementia treatment throughout the …


Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris May 2024

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 …

Understanding The Clinician's View Of Pragmatics In Pediatric Therapy, Shelby Oliver May 2024

Understanding The Clinician's View Of Pragmatics In Pediatric Therapy, Shelby Oliver

Honors Theses

Pragmatics is one of the most integral components of language, yet it often seems to receive little attention in therapy settings. Previous research indicates the importance of intentionally targeting pragmatic skills for children with language disorders and/or autism spectrum disorders, as well as the lack of current pragmatic evaluations. This thesis used an online survey to record how clinicians view pragmatics, how they evaluate pragmatics, and how they target pragmatics. Participants were all certified clinicians, and the research survey featured a variety of open and closed questions. Results revealed a deep pragmatics knowledge base. However, results indicated the use and …


Examining School-Age Children's Use Of Rare Words In Expository Discourse: Applications Of Computerized Analysis, Serena Jae Pedroza May 2024

Examining School-Age Children's Use Of Rare Words In Expository Discourse: Applications Of Computerized Analysis, Serena Jae Pedroza

Open Access Theses & Dissertations

In the school-age years, children use varied discourse styles to convey information. In addition to conversational and narrative discourse, they learn to use expository discourse to explain complex topics. Previous studies have found that compared to conversation, expository discourse samples are generally more syntactically complex (Lundine et al., 2018; Nippold et al., 2005). In addition, the vocabulary used in expository discourse may be more advanced than that in other discourse types. One way to explore vocabulary use in discourse is to measure the rarity of words within samples of discourse. The purpose of this study was to compare typically developing …
