Effect Of Sound Source Location And Spatial Hearing On The Vestibulo-Ocular Reflex (Vor), Mary Easterday Dec 2020

Effect Of Sound Source Location And Spatial Hearing On The Vestibulo-Ocular Reflex (Vor), Mary Easterday

Theses and Dissertations (ETD)

Accurate measurement of the vestibulo-ocular reflex (VOR) is imperative in differential diagnosis of vestibular disorders and balance function. However, the assessment protocol faces a number of limitations, including the need to control for extra- vestibular sensory factors such as hearing. Previous research has shown that the use of an auditory stimulus can have a significant effect on functional measures of balance, and many have contributed effects to be the result of spatial hearing. However, no studies have directly assessed the effect of speaker location on the VOR nor investigated correlations of functional spatial hearing with the VOR. Therefore, the aims …

An Exploration Of Audiologists' Readiness To Adopt Connected Hearing Healthcare For Remote Hearing Aid Fitting, Luisa Natalia Perez Velez

Electronic Thesis and Dissertation Repository

Background: Globally, the increasing prevalence of hearing loss and need for improved access to hearing healthcare services, highlights the growing need for alternative service delivery models. A Connected Health model emerges as a solution for this need, focusing on the use of telecommunication technologies. This model, extended to audiology, can help to better ‘connect’ a patient to their own care process and to their provider during audiological diagnostics, treatment, and management services, at a distance and in an effective and timely manner. The strong capacity for and underutilization of Connected Audiology within current aural (re)habilitation service models have led to …


Audiovisual Integration During Novel Word Learning Among School-Aged Children With Cochlear Implants, Kristen Elizabeth Thompson Thornton Nov 2020

Audiovisual Integration During Novel Word Learning Among School-Aged Children With Cochlear Implants, Kristen Elizabeth Thompson Thornton

Theses and Dissertations (ETD)

Objective. It is well established that being able to see someone’s mouth move as they speak boosts speech perception for children with cochlear implants (CIs). Thus, children with CIs are often instructed to orient themselves toward the person they are listening to, to gain access to visual speech cues. Children with CIs who are better “audiovisual integrators,” or those who experience an auditory-visual (AV) enhancement effect (higher performance for AV information than auditory-alone (AO) or visual-alone (VO)), are more likely to have better speech and language outcomes after receiving their CI than children with poorer AV integration skills. While AV …


Verbal Response Inhibition And Stuttering In Adults, Shanley Belle Treleaven Oct 2020

Verbal Response Inhibition And Stuttering In Adults, Shanley Belle Treleaven

LSU Doctoral Dissertations

Many adults who stutter (AWS) attempt to modify or suppress their stuttered speech daily. The ability to effectively suppress motoric behavior after initiation relies on executive functions such as inhibition – specifically verbal inhibition – a challenging task regardless of clinical status. Minimal published data are available about verbal inhibition in non-stuttering adults, and no data are available for AWS. Researchers have reported slower inhibition for AWS during manual tasks, but inconsistent relationships have been found between manual and verbal inhibition. It is often presumed that inhibition differences in AWS, if detected, would be associated with greater difficulties suppressing the …

Comparison Of High-Tech Augmentative And Alternative Communication Interfaces: Do Age And Technology Experience Matter?, Surani Gopika Nakkawita

LSU Doctoral Dissertations

Previous research has demonstrated that individuals with stroke-induced aphasia can use augmentative and alternative communication (AAC) when they cannot meet their communication needs using spoken language (Dietz, Weissling, Griffith, McKelvey, & Macke, 2014; Purdy & Van Dyke, 2011). Of the various interfaces found in the different AAC systems, the grid display and the visual scene display (VSD) have been used by individuals with aphasia (Hough & Johnson, 2009; Dietz et al., 2018). However, there is a scarcity of research examining the comparative usefulness of these interfaces.

This prospective study attempted to understand how neurologically healthy individuals of different ages and …

The Impact Of Temporal Resolution On Clinical Decision-Making For Individuals With Dysphagia, Shauna Corinne Murray Jul 2020

The Impact Of Temporal Resolution On Clinical Decision-Making For Individuals With Dysphagia, Shauna Corinne Murray

Speech and Hearing Sciences ETDs

INTRODUCTION: Dysphagia, or a disordered swallow, affects up to 1 in 25 individuals in the United States. The gold standard for assessing dysphagia is the videofluoroscopic evaluation of swallowing (VFES). This allows the clinician to observe the swallow anatomy in motion via an X-ray movie, which historically was recorded at 30 frames per second. In recent years VFES have been performed at less frames per second due to radiation concern. This project investigates the effect of using lower temporal resolutions on assessment of video-fluoroscopic swallow studies.

METHODS: In this investigation, 30 swallow studies, all acquired at 30 frames per second, …

The present study investigated the prosodic profile of seven adults with Down syndrome (18;07-34;11 years) using the Profiling Elements of Prosody for Speech and Communication (PEPS-C), and compared the group’s expressive and receptive prosodic abilities to a group of seven adults with mixed-etiology intellectual and developmental disability (29;02-37;07 years) matched on nonverbal ability. Data analyses showed that the group with Down …


The Auditory Radiation In Traumatic Brain Damage: Diffusion Tensor Imaging Study, Jane Walsh May 2020

The Auditory Radiation In Traumatic Brain Damage: Diffusion Tensor Imaging Study, Jane Walsh

Honors Theses

Hearing loss is a known symptom among people who suffer from traumatic brain injuries. Studies have shown that sensorineural hearing loss is the most common type of hearing loss resulting from traumatic brain injury. However, it is not well understood whether the auditory pathway is affected by traumatic brain injury. In this study, we examined the auditory radiation, using diffusion tensor imaging data and probabilistic tractography. Fifty-three veterans with traumatic brain injury and forty-four veterans without traumatic brain injury are compared. There was no significant difference in fractional anisotropy of the auditory radiation between those with and without traumatic brain …


Induction Of Nocebo Effects By Verbal Suggestions During The Caloric Test, Abbey Weist May 2020

Induction Of Nocebo Effects By Verbal Suggestions During The Caloric Test, Abbey Weist

Dissertations, 2020-current

The caloric test is the most frequently performed vestibular diagnostic test and is considered the “gold-standard” for the assessment of the peripheral vestibular system. Using a warm or cool stimulus, the caloric test alters the temperature gradient in the vestibular system resulting in nausea and dizziness. The nocebo effect is a phenomenon that can occur when negative expectations result in negative effects. No study has examined whether expectations of nausea and dizziness during the caloric test enhance the experience of unwanted symptoms. The purpose of this investigation was to determine whether a nocebo response can be elicited during the caloric …


Music And Speech Perception In Pre-Lingually Deafened Young Listeners With Cochlear Implants: A Preliminary Study Using Sung Speech, Harley J. Wheeler May 2020

Music And Speech Perception In Pre-Lingually Deafened Young Listeners With Cochlear Implants: A Preliminary Study Using Sung Speech, Harley J. Wheeler

Dissertations, 2020-current

Timbre and pitch cues, though definitionally and physically distinct characteristics of sound, are attributes of all sound signals. A body of literature has shown that alteration of one characteristic can influence the perception of the other; e.g., speech spoken with an atypical contour of pitch can influence a listener's accuracy in identifying the words spoken; conversely, whether a melodic contour is presented via a MIDI piano representation or as sung speech can influence the accuracy of identification of the pitches' contour. Trends for these interactions have been documented for normal hearing children and adults, as well as postlingually deafened adult …


Vestibular Evoked Myogenic Potentials And Postural Control In Adults With Age-Related Hearing Loss, Steven Michael Doettl May 2020

Vestibular Evoked Myogenic Potentials And Postural Control In Adults With Age-Related Hearing Loss, Steven Michael Doettl

Theses and Dissertations (ETD)

It is well-documented that auditory thresholds decrease with age, which can be referred to as Age-related hearing loss (ARHL). ARHL is one of the most common conditions affecting older adults and is associated with several conditions including decreased postural stability and falls. Age-related changes to auditory function have been attributed to, through histopathological study, specific degradation of the sensory, supporting, and afferent structures of the cochlea. Vestibular function, as measured through vestibular evoked myogenic potentials (VEMPs) also show decreases with age. VEMPs are a measurement of evoked potentials generated by auditory stimulation of the utricle and saccule measured through a …

Development Of The Caregiver-Child Auditory Skills Tracking (Cast) Scale: A Pilot Study On Caregiver Implementation Via International Telepractice, Elizabeth Ocampo-Roman May 2020

Development Of The Caregiver-Child Auditory Skills Tracking (Cast) Scale: A Pilot Study On Caregiver Implementation Via International Telepractice, Elizabeth Ocampo-Roman

Graduate Theses and Dissertations

Parent engagement is a key component during early language development for all children, but particularly for a child with hearing loss. Through the application of technology-based models of service delivery such as telehealth, researchers have found an increase in parent-child engagement during auditory-verbal therapy (AVT) sessions due to the physical absence of the provider and parents becoming the primary language facilitators. However, current measures of parent-child interactions do not have a coding system to monitor facilitation of auditory skills. This present study will discuss the development of the Caregiver-Child Auditory Skills Tracking (CAST) Scale to track progress of caregiver implementation …


Advanced Phenotyping Of Otosclerosis In An Ontario Population And Two Large Newfoundland Families, Matthew B. Lucas Apr 2020

Advanced Phenotyping Of Otosclerosis In An Ontario Population And Two Large Newfoundland Families, Matthew B. Lucas

Electronic Thesis and Dissertation Repository

Otosclerosis is a relatively common hearing loss disorder characterized by abnormal bone growth in the otic capsule leading to stapes fixation. In approximately half of cases, otosclerosis is inherited as an autosomal dominant trait. Typically, gene discovery efforts rely on surgical confirmation, audiometry and occasionally acoustic reflexes to identify affected cases of otosclerosis within families, requiring that the otosclerosis was at an advanced stage to be detected. This makes it difficult to identify individuals with early otosclerosis. The use of advanced phenotyping to identify cases of otosclerosis was tested in an Ontario otosclerotic population as well as in two large …
