Speech Pathology and Audiology Faculty Research and Publications

Providing high-quality literacy instruction in early childhood may positively affect the long-term outcomes of children from disadvantaged backgrounds. Previous research has shown that educators are generally lacking in their own phonological awareness knowledge and skills which could negatively impact the provision of effective instruction in code-focused early literacy skills. The purposes of this pilot study were to examine the effects of differing dosages of professional development in phonological awareness on early childhood educators’ (ECEs) own phonological awareness skills and instructional practices, and to examine the effects on child outcomes. The comparison group consisted of 10 ECEs who were receiving professional …

Developing Ecologically Valid Clinical Tools For Persons With Tbi: Understanding The Role And Impact Of Distractions, Deanna Pinnow

Theses and Dissertations--Rehabilitation Sciences

There is a critical need for the development of ecologically valid clinical tools to assess real-life cognitive functioning in persons impacted by traumatic brain injury (TBI). Chronic cognitive impairments that are exacerbated by distractions are one of the core factors contributing to poor home and community re-integration post injury. Simulation-based digital platforms (i.e., virtual reality, augmented reality, and mixed reality) have become potential solutions for eliciting real-world cognitive performance in clinical settings. Yet, there is a paucity of research investigating the role and impact of distractions on cognition. As a result, there is no clear framework of measuring distractions to …

The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman

Graduate Theses/Dissertations

Choral singing is a popular activity in the United States. Choral singers are often encouraged to warm up vocally before they sing. Considering voice conditions, like presbyphonia, that can develop shortly after retirement, more research about vocal warm-ups is needed for those over the age of 55. This study assesses the effects of various durations of vocal warm-ups on subjective and objective measures of the singing voice using a within-groups design with randomized condition order. Nine participants performed vocal warm-ups for 0, 5, 10, and 15 minutes. A song sample was then recorded and sent to two expert raters who …

The purpose of this research is to determine the levels of ASD knowledge in the Hispanic community in Bowling Green, the barriers that may contribute to why ASD is underdiagnosed in Hispanic children, and how to mitigate these barriers. This research analyzes the results of a survey, called the “Autism Spectrum Knowledge Scale- General Population Version”, administered to 51 participants from the Hispanic population of …

Differences Between Monolinguals And Bilinguals In Phonetic And Phonological Learning And The Connection With Auditory Sensory Memory, Laura Spinu, Jiwon Hwang, Mariana Vasilita

Publications and Research

Bilingualism has been linked with improved function regarding certain aspects of linguistic processing, e.g., novel word acquisition and learning unfamiliar sound patterns. Two non mutually-exclusive approaches might explain these results. One is related to executive function, speculating that more effective learning is achieved through actively choosing relevant information while inhibiting potentially interfering information. While still controversial, executive function enhancements attributed to bilingual experience have been reported for decades. The other approach, understudied to date, emphasizes the role of sensory mechanisms, specifically auditory sensory memory. Bilinguals outperformed monolinguals in tasks involving auditory processing and episodic memory recall, but the questions whether …

Traumatic Brain Injury In Pediatrics, Natalie Deibel

Williams Honors College, Honors Research Projects

Traumatic Brain Injury (TBI) is an acquired brain injury as a result of an external force to the head. Common causes for these injuries include falls, motor vehicle accidents, sports, and abuse. The affected location of the brain, severity, and age at the time of injury affect what deficits are present. Resulting deficits can be in speech, language, behavior, motor, and cognition/executive functions (Manasco, 2020). Traumatic brain injuries can affect all ages. No parent wants to experience their child going through this. TBIs do not just affect the patient but also loved ones. During this difficult time, parents or caregivers …

Speech-Language Pathology Students' Perspective Of Working With Older Adults, Anna Hamill

Williams Honors College, Honors Research Projects

There is an increasing demand for speech language pathologists (SLPs) willing to work with older adults. Demographic trends warn that the number of people over 65 will double by 2050 (Vincent, 2010). Studies reveal that only 37.3% of SLP students prefer to work with older adults after graduation (Leonard et al., 2016). Ageism is affecting speech-language pathology and related health care professions. Research within the last five years has shown that ageism towards older adults exists across multiple medical professions in all fields and settings (Heape et al., 2020). Interdisciplinary fields report negative feelings towards older adults (Ortiz-Rubio et al., …

Passive Earplug Including Helmholtz Resonators Arranged In Series To Achieve Broadband Near Zero Occlusion Effect At Low Frequencies, Kevin Carillo, Franck Sgard, Olivier Dazel, Olivier Doutres

Études primaires

The use of passive earplugs is often associated with the occlusion effect: a phenomenon described as the increased auditory perception of one's own physiological noise at low frequencies. As a notable acoustic discomfort, the occlusion effect penalizes the use and the efficiency of earplugs. This phenomenon is objectively characterized by the increase in sound pressure level in the occluded ear canal compared to the open ear canal. Taking inspiration from acoustic metamaterials, a new design of a three-dimensional printed “meta-earplug,” made of four Helmholtz resonators arranged in series, is proposed for achieving near zero objective occlusion effect measured on artificial …
