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 …

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 …

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 …

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 …

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 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. …

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 …

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.

The Interaction Between Phonological Reading Skills And Executive Functioning In Adults With Cochlear Implants, Tierney Marie Maurer

Undergraduate Honors Thesis Collection

Little research has been conducted concerning the interaction between phonological reading skills (the ability to recognize and manipulate the sounds of language) and executive functioning (a set of processes that are necessary for the cognitive control of behavior) in adults with hearing loss. The current study examined the potential association between phonological reading skills, hearing loss, and executive functioning in post-lingually deaf and hard of hearing adults who use cochlear implants. Two hypotheses were tested: 1) adult cochlear implant users have weaker executive functioning and phonological reading skills compared to their hearing peers; 2) adults with hearing loss who use …
