Loudness Matching In Individuals With Parkinson’S Disease And Hypophonia, Catherine Johnson

Electronic Thesis and Dissertation Repository

The purpose of the present study was to investigate speech loudness perception in 15 individuals with Parkinson’s disease (IWPD) and hypophonia (reduced speech intensity) and 15 healthy control (HC) participants. A loudness matching procedure was used to examine conditions involving speech loudness targets presented at various levels (60 to 80dB SPL). The loudness response conditions included manually controlled audio playback of external speech, self-vocalized speech, amplified self-speech, and speech projected to a distance of 2 meters. For most of the loudness matching conditions, the PD group did not demonstrate the predicted deficit in loudness matching. In some loudness matching conditions, …

The Directional Effect Of Target Position On Spatial Selective Auditory Attention, Heesung Park

Dissertations, 2020-current

Spatial selective auditory attention plays a crucial role in listening in a mixture of competing speech sounds. Previous neuroimaging studies have reported alpha band neural activity modulated by auditory attention, along with the alpha lateralization corresponding to attentional focus. A greater cortical representation of the attended speech envelope compared to the ignored speech envelope was also found, a phenomenon known as 'neural speech tracking’. However, little is known about the neural activities when attentional focus is directed on speech sounds from behind the listener, even though understanding speech from behind is a common and essential aspect of daily life. The …

Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher

University Honors Theses

This study evaluates the impact of memory skills (procedural, declarative, and working) and sound discrimination abilities, on the ability of adults with and without Language Learning Disability (LLD) to learn two sound-category structures, one designed to be learned implicitly and the other designed to be learned explicitly. This design tests a theorized etiology for LLD, the Procedural Deficit Hypothesis (PDH), which posits that LLD is caused by selective impairments to procedural memory and implicit learning. It also serves to evaluate factors and conditions that contribute to success in second-language learning for adults, who are less neurologically suited to the task …

Caring For Individuals Who Are Experiencing Homelessness: An Audiologist’S Toolkit, Jenna Marie Sparacio

Dissertations, Theses, and Capstone Projects

National-level counts for individuals experiencing homelessness have been steadily on the rise. People experiencing homelessness face extraordinary barriers and challenges in accessing health care services, including hearing healthcare. Additionally, there is a high prevalence of self- reported hearing difficulties and hearing handicap among people experiencing homelessness. Hearing loss status and management is often not prioritized in healthcare settings, and treatment plans are not typically modified to best address the hearing needs of individuals who are homeless. This evidence-based toolbox for audiologists was developed to help understand and mediate healthcare barriers that people experiencing homelessness face, as well as to help …

Exploring The Potential Of Hearing Screening Smartphone Applications To Enhance Access To Hearing Healthcare: A Literature Review, Adam Sulaiman

Dissertations, Theses, and Capstone Projects

In 2016, the National Academies of Sciences (NAS) published a landmark consensus report with several recommendations to enhance the availability and affordability of hearing healthcare in the United States. Among the most notable of the recommendations was the creation of a new category of FDA-approved Over-the-Counter (OTC) hearing aids. Unlike the traditional hearing aid model, which requires a comprehensive hearing test by a hearing health professional prior to purchase, OTC hearing aids would be directly available for sale to any American adult with a self-perceived mild-to-moderate degree of hearing loss. This proposal has now become reality with the passage of …

Audiological Management Of Children With Down Syndrome: A Toolkit For Caregivers, Natalie Lisiewicz

Dissertations, Theses, and Capstone Projects

Children with Down syndrome may have multiple medical co-morbidities. This can result in an overwhelming number of medical appointments and information for caregivers to keep track of. Middle ear dysfunction, among other otologic abnormalities, is common in the Down syndrome population, and the presence of these conditions will result in referrals to an audiologist to monitor hearing sensitivity. While hearing may not be the most pressing concern as compared to a possible life-threatening condition such as a heart defect, it is still a crucial factor in a child’s overall development.

This toolkit is designed with the intention of educating caregivers …

Examining The Effect Of Training Using Natural And Noise-Vocoded Sentences On Noise-Vocoded Speech Perception In Normal-Hearing Listeners, Alexis Leiderman

Dissertations, Theses, and Capstone Projects

Auditory training has been shown to be an intervention strategy that may improve speech perception abilities in individuals with and without hearing loss. Within the cohort of individuals with hearing loss, auditory training has also been shown to have an improvement on speech perception in cochlear implant users. In several training studies, normal-hearing listeners have been exposed to noise-vocoded speech using auditory training paradigms to mimic how cochlear implant users may in turn be affected by these paradigms. These studies have highlighted certain areas for improvement in speech perception abilities based off of the training paradigms put in place. Several …

Examining The Effect Of Talker Familiarity Using Familiar And Unfamiliar Talkers On Noise-Vocoded Speech Perception In Normal-Hearing Listeners: A Training Study, Daria N. Collins

Dissertations, Theses, and Capstone Projects

Auditory training studies utilizing stimuli that are applicable to real-world processing of speech have been shown to improve speech perception abilities in normal hearing populations, those with hearing loss, and cochlear implant wearers. In particular, exposing normal hearing adults to noise-vocoded speech via auditory training studies has been shown to not only simulate the perceptual experience of a cochlear implant wearer, but have demonstrated promising improvements on speech perceptual abilities via the training paradigm. Additionally, studies have highlighted various variables that impact speech perception, including, talker familiarity. Talker familiarity has been shown to enhance speech perception both in listeners with …

Age-Related Decline In Neural Synchrony And The Ffr, Haley Szabo

Dissertations, 2020-current

It is a known phenomenon that speech understanding in background noise declines with advancing age. Although there is ample evidence of behavioral measures declining with age, there is less physiologic evidence. This study hypothesizes that the FFR will be degraded with advancing age, consistent with poorer phase locking. This is hypothesized to be present even in people with audiograms within normal limits. A second hypothesis is that middle-aged adults will have degraded neural representation as frequency increases, compared to a younger normal hearing group which will have better high frequency neural representation than the middle-aged group. Subjects were divided into …

Student Academic Conference

This literature review was completed to explore emerging literacy skills in children who use Augmentative and Alternative Communication (AAC) for communication purposes. This paper explored the differences in language and literacy learning for children who utilize AAC. For children in early developmental phases of language, AAC played a role in both receptive and expressive language. Skills learned in receptive and expressive language can be shaped into what is considered early literacy skills. Through findings by researchers and experts in the field of AAC and speech-language pathology this paper defined specific interventions and supports that can be implemented during the development …

Variation In How Cognitive Control Modulates Sentence Processing, Abhijeet Patra, Jeremy Kirkwood, Erica L. Middleton, Malathi Thothathiri

Moss-Magee Rehabilitation Papers

Prior research suggests that cognitive control can assist the comprehension of sentences that create conflict between interpretations, at least under some circumstances. However, the mixed pattern of results suggests that cognitive control may not always be necessary for accurate comprehension. We tested whether cognitive control recruitment for language processing is systematically variable, depending on the type of sentential ambiguity or conflict, individual differences in cognitive control, and task demands. Participants completed two sessions in a web-based experiment. The first session tested conflict modulation using interleaved Stroop and sentence comprehension trials. Critical sentences contained syntax-semantics or phrase-attachment conflict. In the second …

Examining Perception And Understanding Of Stroke And Its Risk Factors In A Rural Population, Mackenzie King, Gabrielle Scarpa, Mary Gardiner

Theses & Honors Papers

Stroke, also sometimes referred to as a brain attack, occurs when there is a blockage in blood supply to the brain or when a blood vessel bursts within the brain (CDC, 2022). Rural populations have a higher incidence of stroke and higher stroke mortality in the United States (Howard et al., 2017). Although there is a higher incidence rate of stroke in rural populations, researchers have also found that these populations appear to have limited knowledge on stroke and its risk factors. The current study employed a non-experimental descriptive design that explored stroke knowledge in adults residing in rural populations …
