Development Of Psychoacoustic Screening Tests For Hearing Assessments, Minh Vu Duong
Development Of Psychoacoustic Screening Tests For Hearing Assessments, Minh Vu Duong
Electronic Thesis and Dissertation Repository
The evaluation of suprathreshold listening abilities in audiological assessment is often minimized despite the valuable insight it produces about auditory discrimination skills. These capabilities can be assessed from psychoacoustic tests. However, measuring these abilities requires a significant amount of time. Therefore, screening tests were developed for frequency discrimination, gap detection, and amplitude modulation tests to identify individuals for whom these skills are most likely to be useful. The purpose of this project was to determine the ability of this screening tool to predict good performers and determine who is likely to have reduced skills and require full threshold assessment. Thirty …
Myeloarchitectonic Maps Of Cat Auditory Cortex, Austin Robertson
Myeloarchitectonic Maps Of Cat Auditory Cortex, Austin Robertson
Electronic Thesis and Dissertation Repository
The cerebral cortex contains myriad cortical areas that differ in structure, function, and connectivity. Current methods of delineating cortical structures and their subregions are insufficient for in vivo applications, either being highly invasive or requiring a detailed knowledge of a region’s tuning properties. To address this, we seek to establish a structural biomarker capable of delineating the cortex that possesses a non-invasive correlate. We explore myelin as a potential candidate by evaluating its efficacy in parcellating the feline auditory cortex through the generation of depthwise myelin density profiles for each of the 13 auditory cortical subregions. Our analyses revealed significant …
User Preferences For Hearing Aid Features: Outcomes, Concepts, And Test Construction, Hasan Saleh
User Preferences For Hearing Aid Features: Outcomes, Concepts, And Test Construction, Hasan Saleh
Electronic Thesis and Dissertation Repository
Modern hearing aids can vary in both digital signal processing (DSP) and non-signal processing (non-DSP) features. The complexity and availability of these features can differ at opposite ends of the technology spectrum, potentially influencing aided benefit and preference. Furthermore, the amount of feature choices in modern hearing aids has led to increasing complexity in the selection process.
The first aim of this dissertation was to investigate the aided benefit and preference differences between premium and entry-level hearing aids, and to investigate the drivers of any preference differences. No significant differences were found between the entry-level and premium hearing aids in …
Language-Based Strategies That Support Person-Centered Communication In Formal Home Care Interactions With Persons Living With Dementia, Reanne G. Mundadan
Language-Based Strategies That Support Person-Centered Communication In Formal Home Care Interactions With Persons Living With Dementia, Reanne G. Mundadan
Electronic Thesis and Dissertation Repository
Background. Several studies recommend language-based strategies for communication with persons living with dementia. Language-based strategies improve coherence, clarity, reciprocity, and continuity of interactions. Person-centered communication (PCC) strategies are the gold standard, including facilitation, recognition, validation, and negotiation. Only one study has examined the overlap between language-based strategies and PCC in long-term care. Little is known about which language-based strategies support PCC in home care. Accordingly, this study investigated the overlap between language-based strategies and PCC in home care interactions. Method. Conversation analysis of 30 audio-recorded routine care interactions between home care workers and persons living with dementia was conducted. The …
Practice-Based Research In Speech-Language Pathology, Meghan Vollebregt
Practice-Based Research In Speech-Language Pathology, Meghan Vollebregt
Electronic Thesis and Dissertation Repository
Practice-based research is an active and collaborative approach to clinical research that minimizes the research-practice gap. Practice-based research involves collecting data in practice to answer questions that arise from clinical practice. The findings from this research then inform future practices. Though over the past two decades there has been a significant increase in knowledge translation activities, especially the use of collaborative partnerships, the integration of these practices in speech-language pathology is in its infancy. In this thesis, I investigate the role of practice-based research in speech-language pathology. In Chapter 2, I first examine the current role of practice-based research in …
Approaches To Examining The Role Of Auditory Evoked Potentials In Early Language Development, Alyssa Janes
Approaches To Examining The Role Of Auditory Evoked Potentials In Early Language Development, Alyssa Janes
Electronic Thesis and Dissertation Repository
Previous research has suggested a relationship between auditory evoked potentials (AEPs) and spoken language proficiency, but their interactions during the earliest stages of development are not well understood. AEP-Age, an index that estimates the maturity of a child’s AEP relative to same-aged peers, has been effective in investigating this relationship in school-aged children, but has yet to be applied to younger populations. This thesis includes two Stage 1 Manuscripts (Registered Reports) for future studies to (a) assess the utility of AEP-Age to predict chronological age and language ability in 18-48-month-old children, and (b) investigate the relationship between AEP-Age and …
