What Of It? Coding The Unmarked Of-Preposition In Language Samples From Young Aae Speakers, Denise A. Finneran, Maura J. Moyle, Alaina Nash, Sixia Chen

Speech Pathology and Audiology Faculty Research and Publications

We examined the of-preposition in language samples because it is a highly variable feature that can be marked or unmarked (e.g., “out [of] the door”) depending on context. Children who speak African American English (AAE) produce unmarked of-prepositions in contexts that are universal across AAE and General American English (GAE; e.g., “out [of] the window”) and in contexts specific to the AAE dialect (e.g., “out [of] the car”). Guidance in the literature on this variability is limited for language sample analysis. Participants included 113 children who spoke AAE. We examined contexts with unmarked of-prepositions in narrative language samples in a …

A Developmental Texture Framework For Food Texture Progression: Implications For Feeding Development, Oral Motor Skills, And Pediatric Feeding Disorder, Amy L. Delaney, Sarah Staskiewicz, Suzanne Evans Morris, Sarah Smith-Simpson, Praveen S. Goday

Speech Pathology and Audiology Faculty Research and Publications

The introduction of food textures in a child's first 2 years of life plays a vital role in growth, nutrition, and feeding development. However, the absence of a standardized texture framework for studying texture progression limits both pediatric feeding research and the ability to diagnose pediatric feeding disorder (PFD) based on age-appropriate expectations. To address this gap, authors Delaney and Goday proposed data sharing from the Nestlé Feeding Infant-Toddler Study (FITS) to explore texture progression and define age-appropriate texture expectations. In response, Nestlé assembled a multidisciplinary panel of feeding experts to create standardized textures but did not provide financial or …

Self-Reported Audiological And Vestibular Symptoms Associated With Lyme Disease, Daniella A. Bryan

Dissertations, Theses, and Capstone Projects

Background:

Lyme disease, an infectious vector-borne illness, is carried by the deer tick, Ixodes scapularis, which harbor the spirochete, Borrelia burgdorferi, affecting hundreds of thousands of people in the United States annually. Lyme disease has a multitude of clinical presentations and overlaps with other complex illnesses, making diagnosis and treatment a medical challenge. This distinct bacterium can migrate into any organ system through the mediums of soft tissue, the lymphatic system, and the circulatory system. Despite its prevalence and range in symptomatology, minimal research has been conducted to identify distinct audiological and vestibular symptoms associated with a Lyme …

Localization Of Music In Perceived Motion In Cochlear Implant Users, Madeleine Beyer

Dissertations, Theses, and Capstone Projects

Spatial perception contributes to music perception and enjoyment, yet it remains understudied in cochlear implant (CI) users. Spatial effects in music are often achieved through panning, a tool which redistributes an audio signal level between or among several outputs, creating a perceived sound localization. CI users typically perform worse than normal hearing (NH) listeners on tasks of horizontal localization and music perception when manipulating the actual location of the sound. However, despite the common use of panning in daily use and consumption of music, no previous studies were conducted to examine how panning impacts the listening experience for CI users. …

Bimodal Hearing Vs. Bilateral Hearing: Presenting A Review Of Existing Literature To Assist Audiologists With Determining The Optimal Hearing Modality, Eliana Dachman

Dissertations, Theses, and Capstone Projects

While guidelines exist for cochlear implant candidates, there are no specific established guidelines for bimodal users who are considering a 2nd cochlear implant. The objective of this paper is to critically review the literature addressing the question of comparative performance outcomes for bimodal hearing (one hearing aid in combination with a cochlear implant) and bilateral cochlear implants (two cochlear implants). The inclusion criteria were publications comparing bimodal and bilateral cochlear implant performance on speech perception, localization, and subjective quality. Fifteen qualifying papers were identified and analyzed. The results indicate that there are possible advantages to bilateral cochlear implants when assessing …

Benchmarking Machine Learning Models In Lesion-Symptom Mapping For Predicting Language Outcomes In Stroke Survivors, Deepa Tilwani, Christian O'Reilly, Nicholas Riccardi, Valerie L. Shalin, Dirk B. Den Ouden, Julius Fridriksson, Svetlana V. Shinkareva, Amit P. Sheth, Rutvik H. Desai

Communication Sciences and Disorders Faculty Articles and Research

Several decades of research have investigated the neural connections between stroke-induced brain damage and language difficulties. Typically, lesion-symptom mapping (LSM) studies that address this connection have relied on mass univariate statistics, which do not account for multidimensional relationships between variables. Machine learning (ML) techniques, which can capture these intricate connections, offer a promising complement to LSM methods. To test this promise, we benchmarked ML models on structural and functional MRI to predict aphasia severity (N = 238) and naming impairment (N = 191) for a cohort of chronic-stage stroke survivors. We used nested cross-validation to examine performance along …

Distinct Brain Age Gradients Across The Adult Lifespan Reflect Diverse Neurobiological Hierarchies, Nicholas Riccardi, Alex Teghipco, Sarah Newman-Norlund B.S., M.A., Roger Newman-Norlund Ph.D., Ida Rangus, Chris Rorden, Julius Fridriksson Ph.D., Leonardo Bonilha

Faculty Publications

‘Brain age’ is a biological clock typically used to describe brain health with one number, but its relationship with established gradients of cortical organization remains unclear. We address this gap by leveraging a data-driven, region-specific brain age approach in 335 neurologically intact adults, using a convolutional neural network (volBrain) to estimate regional brain ages directly from structural MRI without a predefined set of morphometric properties. Six distinct gradients of brain aging are replicated in two independent cohorts. Spatial patterns of accelerated brain aging in older adults quantitatively align with the archetypal sensorimotor-to-association axis of cortical organization. Other brain aging gradients …

The Effects Of Counseling On Patient Usage And Satisfaction With Wearing Hearing Aids, David Frazier

Doctoral Dissertations and Projects

Hearing aids are a vital intervention for managing hearing loss, yet their adoption remains disproportionately low across age groups. Only 30% of adults aged 70 and older and a mere 16% of adults aged 20 to 69 who could benefit from hearing aids report ever using them. This study explored whether counseling and education, within the framework of aural rehabilitation therapy (ART), could improve hearing aid satisfaction and usage rates. Participants with mild-to-profound sensorineural hearing loss were evaluated using the Satisfaction with Amplification in Daily Life (SADL) questionnaire, which was administered during hearing aid fittings to gauge the effectiveness of …

Neuroanatomical And Morphometric Differences In Children Who Stutter, Mohammad A. Khan

Honors Scholar Theses

Childhood-Onset Fluency Disorder commonly known as stuttering is a neurodevelopmental speech disorder characterized by disruptions in speech fluency. While genetic and neurobiological factors are implicated, the structural brain differences underlying stuttering remain unclear. This study investigated neuroanatomical alterations in children who stutter (CWS) compared to typically fluent children (TFC), focusing on gray matter volume, cortical thickness, and surface area in speech-related regions; the Inferior Frontal Gyrus, Middle Temporal Gyrus, and Pre-motor Operculum. High-resolution MRI data from 100 children (48 CWS, 52 TFC) aged 3–12 years were analyzed using FreeSurfer. Group comparisons revealed no statistically significant differences in cortical thickness, surface …

The Application Of Time-Frequency Analysis To Ocular Vestibular Evoked Myogenic Potentials, Hannah R. Richardson

Dissertations, 2020-current

Ocular vestibular evoked myogenic potentials (oVEMPs) are produced by highly synchronous bursts of extraocular muscle activity in response to bone or air-conducted stimuli. Surface electromyography (EMG) electrodes can be used to record these responses which reflect utricular function. The traditional analysis of oVEMPs has been limited to time-domain waveform measurements, such as amplitude and latency of response peaks.

Recently, a method grounded in synchrony-based time-frequency analysis was successfully applied to cervical vestibular evoked myogenic potentials (cVEMPs) by Clinard et al. (2022). This approach to VEMP analysis can be used as a means to differentiate synchrony from amplitude, quantifying how phase …

The Relationship Between The Vestibulo-Ocular Reflex And Vestibular Perception In Trained Dancers Using Sinusoidal Harmonic Acceleration Testing, Diana Trinidad

Dissertations, 2020-current

Early studies have found that engaging in vestibular training, such as dance, may result in enhanced VOR suppression and changes in vestibular perception (e.g., lower sensations of vertigo) attributed to top-down modulation of subcortical neuronal networks and changes in the cerebellum. Dancers use spotting techniques to help control dizziness which involve holding their gaze on a visual object at eye level as they turn. As a result of this training, dancers become habituated to vestibular stimuli leading to lower VOR responses and decreased sensations of vertigo. This study investigated the relationship between the vestibulo-ocular reflex (VOR) and vestibular perception in …

Intertrial Coherence As A Measure Of Synchrony In Ocular Vestibular Evoked Myogenic Potentials And The Effect Of Gaze Angle, Sydney Brown

Dissertations, 2020-current

Ocular vestibular evoked myogenic potentials (oVEMPs) are produced by highly synchronous bursts of extraocular muscle activity in response to stimuli. These responses reflect utricular function and can be recorded using surface electromyography electrodes. Traditional analysis of oVEMPs is limited to time-domain waveform measurements, such as amplitude and latency of response peaks. Objective synchrony-based measures have not yet been applied to the analysis of oVEMPs, particularly in the comparison of synchrony across gaze angles. We followed the new time-frequency method of analysis developed by Clinard et al. (2022) that was successfully applied to cervical VEMPs to quantify response synchrony. Air-conducted oVEMPs …

Establishing The Feasibility Of Sustained Sinusoidal Cervical Vestibular Evoked Myogenic Potentials In Young Adults, Ashton Fowlkes

Dissertations, 2020-current

Cervical vestibular evoked myogenic potentials (cVEMPs) are used in clinics and research to assess the function of primarily the saccule. cVEMPs are typically stimulated with transient clicks or tone bursts through air conduction and are recorded from the sternocleidomastoid (SCM) muscle. The SCM is contracted by turning the head either left or right. In this study, we used sustained sinusoidal bone conducted stimuli. Using this new stimulus method allowed us to look at the possibility of a sustained cVEMP response, compared to the typically recorded transient response, as well as analyze the amplitude and signal-to-noise ratio (SNR) of the responses. …

A Literature Review: Understanding Gestalt Language Processing In Autism Spectrum Disorder, Jordynn L. Urwiler

Honors Thesis

Gestalt language processing (GLP) is not a new idea in the field of speech-language pathology. However, the topic has recently become more popular among practicing speech-language pathologists (SLPs), and the neurodiversity movement may be partially responsible. Advocates for autism spectrum disorder (ASD) have shifted away from using behavioral approaches that try to “fix” autistic1 cognition and communication patterns. Although Analytical Language Processing (ALP) is the typical path for language development, it is now understood that GLP may be a valid form of language acquisition used by both neurotypical and neurodivergent people. The purpose of this literature review is to provide …

Background

The communicative effectiveness of persons with aphasia (PWA) has been assessed through a range of functional communication measures. However, variability in interpretations of what is covered by the term “functional communication” may have resulted in challenges to the implementation of appropriate and consistent patient-centred evaluations, with different measures focusing on subsets of the components of functional communication.

Aims

This paper aims to examine the current literature on informal and formal evaluation of functional communication in PWA and to identify gaps in currently available assessment tools.

Methods

This scoping review included studies published between 1965 and 2024 that assessed functional …

Intervention Techniques Targeting Echolalia: A Scoping Review, Adriana Dinello, Allison Gladfelter

CISLL Publications

Purpose:

Although echolalic speech is found in typical development, echolalia is most commonly associated with autism. As such, echolalia has frequently been the focus of various interventions aimed at autistic children. Recent research and the voices of autistic self-advocates indicate that echolalia serves as a meaningful form of communication or functionally supports self-regulation. As a result, the literature on how, or whether, to target echolalia in therapy is full of philosophically diverse approaches. To support evidence-based practice, the purpose of this scoping review was to inform speech-language clinicians about current research on interventions targeting echolalia and how disagreement on this …

Speech Stigma: Exploring Predictors Of Attitudes Toward Nonspeaking Autistic Individuals, Kate Herrmann

Honors College Theses

Roughly 30% of autistic individuals are nonspeaking, meaning they do not (or very minimally) communicate with speech. Many nonspeaking individuals have the ability to communicate with others by using augmentative and alternative communication, such as speech-generating devices or communication boards. The purpose of this study was to examine the attitudes of speaking individuals toward nonspeaking autistic people through a survey measuring attitudes and stigma toward nonspeaking people, autistic people, and disabled people, respectively. Predictors of attitudes, such as contact, knowledge, gender, and psychological inflexibility were examined. It was hypothesized that participants who have more contact with and knowledge of nonspeaking, …

How Much Should Consumers With Mild To Moderate Hearing Loss Spend On Hearing Devices?, Vinaya Manchaiah, Steve Taddei, Abram Bailey, De Wet Swanepoel, Hansapani Rodrigo, Andrew Sabin

School of Mathematical & Statistical Sciences Faculty Publications

Background: This study examined the relationship between hearing device price and sound quality. Method: A novel consumer-centric metric of sound quality (“SoundScore”) was used to assess hearing devices’ audio performance. Each hearing device is tested with two fittings. The “Initial Fit” is designed to approximate the most likely fitting for an individual with a mild-to-moderate sloping sensorineural hearing loss. The “Tuned Fit” includes adjusting parameters optimized to hit prescriptive fitting targets (NAL NL2) on an acoustic manikin. Each fitting is evaluated across five dimensions. Both fittings are combined using a weighted average to create a single number from 0 to …

How Individual Differences In Cue Weighting Influence The Link Between Memory And Speech In Noise Perception, Ava Buckmir, Anne Marie Crinnion, Emily Myers

Honors Scholar Theses

Listening to speech is challenging, particularly when there is background noise or ambiguities in the speech signal. Numerous factors impact our ability to understand speech, including age, cognitive processes, and contextual information. But how do we account for these challenges? The types of cues we use may aid us in perceiving ambiguities in speech. Some individuals may rely on semantic cues (higher-level cues), such as how words relate to each other, or they may rely on acoustic-phonetic cues (lower-level cues), such as the durational information in the speech signal itself. But why do individuals differ in the types of cues …

Influence Of Hearing Loss On Self-Reported Hearing Ability And Listening Fatigue In Persons With Aphasia, Ashlyn Kilgore

Poster Presentations

Aphasia is an acquired disorder, often caused by stroke, that results in language deficits. It can greatly impact a person's ability to communicate with others. Cognitive deficits may accompany aphasia. Additionally, hearing loss is a disability likely to co-occur with aphasia, as they both most commonly impact the same age group. When a person has hearing loss, the quality of the auditory signal is degraded when it reaches the brain. The poor signal quality, compounded with linguistic and possible cognitive deficits that are associated with aphasia, makes it more difficult for persons with aphasia (PWA) to comprehend speech.

For all …

Creating A Multi-Sensory Room At The University Of Arkansas, Alexandra R. Smith

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Autism Spectrum Disorder, or autism, is a genetic neurological condition that can affect all aspects of an individual’s life, depending on their symptoms. Autistic people tend to struggle most significantly with social and emotional issues, which often results in declining academic success. With such a multifaceted disability, autistic students can struggle to perform at the same standards as their non-autistic peers, mostly due to the complications from their disability paired with limited accommodations. The consequences of these issues can manifest as lower admission rates, higher dropout rates, and higher stress levels for autistic students. This creative and service-learning honors thesis …
