Difference Or Disorder? Misidentification Of Speech And Language Disorders In Mississippi’S Public Schools, Lori Leachman, Catherine Cotton Dr.

Undergraduate Research Conference

Students who are misdiagnosed with speech and language disorders often miss out on necessary class time and can fall behind their peers. In order to decrease the prevalence of misdiagnoses due to dialectal and linguistic differences, we must first understand how SLPs currently differentiate between typical and disordered speech. In this study, information will be gathered on the current abilities of Mississippi public school SLPs to identify the difference between a speaker that is linguistically diverse and a speaker with disordered speech or language. SLPs will listen to AI generated speech samples–some disordered, some typical, but with non-mainstream dialects–and be …

Examining Cultural Competency In Audiologists Across The United States: A Pilot Survey, Olivia Montoya

Student Research Symposium

• Cultural competency refers to the ability of systems to provide care to patients with diverse values, beliefs, and behaviors, including tailoring delivery to meet patients' social, cultural, and linguistic needs (Betancourt, 2002).

• Limited studies to date have explored the implementation of cultural competence in audiology, which begs the question of how audiologists are fighting against—instead of contributing to—healthcare disparities among ethnic minorities.

Examining Hearing Protection Use In Applied Technology: Frequency, Barriers, And Evidence Of Hearing Loss, Brock Blessing, Cassi Pinto, Willow Ludwig, Blake Roth

SACAD: Scholarly Activities

This study investigated the prevalence of hearing protection usage among applied technology instructors and students and explored factors contributing to non-compliance. Survey data was collected in addition to the completion of basic audiometry screening procedures. Results indicated that while hearing protection devices were as readily available as head and eye protection, they were worn less frequently. Many participants found hearing protection inconvenient or believed it interfered with communication. A gap in education and resources was identified. These findings highlight the need for improved education and reinforcement of hearing conservation practices to increase compliance among applied technology instructors and students.

Proposed Method For Analyzing Cognitive Effects Of Chiari Malformation Type I And The Progression Following Cerebral Tonsil Reduction, Isabella Gleason

Selected Honors Theses

Chiari Malformation Type I (CM-I) is a neurological condition characterized by the descent of cerebellar structures through the foramen magnum. This malformation can be associated with cognitive implications, including impaired executive functioning, slowed processing speed, memory deficits, difficulties with attention and concentration, irregularities in emotional processing, and challenges in communication and fluency. Research indicates that cognitive dysfunction is prevalent in CM-I patients, affecting their daily lives. There are two surgical treatments commonly recommended for CM-I: posterior fossa decompression (PFD) and cerebral tonsil reduction (CTR). While both interventions are supported in the literature, studies on their long-term effects and effectiveness remain …

Cultural Linguistic Bias In Language Assessments For Children, Madison Wester

Spring Showcase for Research and Creative Inquiry

Cultural linguistic bias is present in almost all language assessments for children, such as the Preschool Language Scales (PLS-5) and the Clinical Evaluation of Language Fundamentals (CELF-5). Cultural linguistic bias is bias against those who speak a different dialect, such as African American Vernacular English or Appalachian English. Bias in these assessments leads to over-diagnosing children with language disorders, which is harmful in a number of ways. To decrease this bias, SLPs should take a language sample to assess a child’s natural language. However, this process can be time-consuming, which is why the use of online tools, such as SUGAR, …

Understanding The Relationship Between Executive Function And Language During The Preschool Period, Haya Q. Kidwai

Senior Theses

Executive functions (EFs) are abilities that help us to control our actions, pay attention, and go against automatic responses. EF skills include working memory, inhibition, and cognitive flexibility, all of which develop rapidly during early childhood alongside other developmental abilities like language. In fact, previous research has found a relationship between EFs and language abilities. Therefore, the current study investigated the correlation between EFs and language in the preschool period, a pivotal moment in their development. Specifically, the current study examined the relationship between working memory and inhibition and expressive vocabulary and morphosyntax measures in 7 children 4-6 years old. …

Aging-Related Hearing Decline And Resting State Networks, Cassidy S. T. Ellsworth

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study investigated the effects of age-related hearing decline on functional networks using resting-state functional magnetic resonance imaging (rs-fMRI). The main objective of the present study was to examine resting-state functional connectivity (rsFC) and graph theory-based network efficiency metrics in forty-nine adults categorized by age and hearing thresholds to identify the neural mechanisms of age-related hearing decline. RsFC within key brain networks and auditory-related brain regions, including the default mode network, salience network, dorsal attention network, and primary auditory cortices, was assessed using region-of-interest (ROI)-based and graph theory approaches. Functional metrics, such as rsFC strength and global and local efficiency, …

Clinical Case Study: The Effects Of Saltatory Pneumotactile Stimulation Of Glabrous Hand And Perioral Face On Cerebral Oxygenation, Cognitive Performance, And Sensorimotor Function In An Adult Following Left Hemorrhagic Stroke, Tara L. Hull

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Stroke remains a leading cause of adult disability and a significant global health concern. Effective rehabilitation strategies for cognitive and communicative impairments following stroke are limited (Kuhn & Sharman, 2023). One emerging approach involves repetitive somatosensory stimulation to drive cerebral hemodynamic changes, potentially offering a novel rehabilitative method. Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive, accessible tool for monitoring these changes during stroke recovery. Prior studies suggest tactile stimulation rapidly affects brain hemodynamics (Custead et al., 2015; Oh et al., 2017). This clinical single-case study explored the use of GALILEO saltatory pneumotactile stimulation applied to the face and hand in …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

Investigating Child-Informed Considerations For Animated Picture Symbols Representing Emotion For Aac Use In Children With Asd, Hannah Kitsmiller

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Development of emotional competence is an important area of consideration when supporting individuals who use augmentative and alternative communication (AAC). Emotional competence includes skills related to identifying and communicating about one’s emotions. Individuals who use AAC may struggle to develop strong skills in emotional competence. One potential barrier to developing emotional competence may be access to symbols that facilitate understanding of the represented emotion. Emotions are abstract and challenging to represent in visual symbols. Additionally, evidence suggests individuals with autism spectrum disorder (ASD) may have visual perceptual differences when viewing faces. Current emotion symbols are often depicted using isolated facial …

Honors Program: Senior Projects (Public)

Current research cites effective provider communication as an important factor in improving treatment adherence and the health outcomes of patients. This study examines the effect of provider communication on treatment adherence in patients with chronic illnesses with a specific focus on hypertension and diabetes. Provider communication was measured using patient satisfaction surveys and treatment compliance was measured as the percentage of hypertensive and diabetic patients with a blood pressure below 140/90 mmHg and hemoglobin A1C levels below 9%. A one-way MANOVA revealed that provider communication had no significant impact on the combined treatment compliance variables for hypertension and diabetes (Wilk’s …

The Effect Of Transcutaneous Vagus Nerve Stimulation On Word Memory In Healthy Adults, Haylee Hurt, Cassandra Callahan, Olivia Galpin, Qiang Li

SACAD: Scholarly Activities

Transcutaneous vagus nerve stimulation (tVNS) is a non-invasive technique that has been demonstrated to reorganize the brain neural network based on neuroplasticity. Research shows that tVNS may enhance cognitive performance such as verbal memory, as it may elicit the release of key neurotransmitters, Gamma-aminobutyric Acid (GABA) and Noradrenaline, that modulate cognitive performance and learning. The current study hypothesizes that verbal memory as an important cognitive skill in healthy adults will be improved after receiving tVNS. Results showed that compared to the control group, participants in the experimental group improved their verbal memory manifested in faster reaction times and higher accuracy …
