Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat

Faculty Publications

Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. This hypothesis was directly tested by measuring both forward- and simultaneous-masked psychophysical tuning curves. Sharper filter tuning (i.e., higher Q10) was observed in musicians compared to nonmusicians. Findings suggest musicians' pervasive listening benefits may be facilitated, in part, by superior spectral processing/decomposition as early as the auditory periphery.

Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston

Open Access Theses

Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …

A Model Of Children's Acquisition Of Grammatical Word Categories Using An Adaptation And Selection Algorithm, Teresa Young

Theses and Dissertations

Most children who follow a typical developmental timeline learn the grammatical categories of words in their native language by the time they enter school. Researchers have worked to provide a number of explicit, testable models or algorithms in an attempt to model this language development. These models or algorithms have met with some varying success in terms of determining grammatical word categories from the transcripts of adult input to children. A new model of grammatical category acquisition involving an application of evolutionary computing algorithms may provide further understanding in this area. This model implements aspects of evolutionary biology, such as …

Preliminary Test Of A Real-Time, Interactive Silent Speech Interface Based On Electromagnetic Articulograph, Jun Wang, Ashok Samal, Jordan R. Green

CSE Conference and Workshop Papers

A silent speech interface (SSI) maps articulatory movement data to speech output. Although still in experimental stages, silent speech interfaces hold significant potential for facilitating oral communication in persons after laryngectomy or with other severe voice impairments. Despite the recent efforts on silent speech recognition algorithm development using offline data analysis, online test of SSIs have rarely been conducted. In this paper, we present a preliminary, online test of a real-time, interactive SSI based on electromagnetic motion tracking. The SSI played back synthesized speech sounds in response to the user’s tongue and lip movements. Three English talkers participated in this …

The Efficacy Of Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Julianne Grover Smith Guerra

Theses and Dissertations

Recent research indicates that many children with Language Impairment (LI) have difficulty with social communication skills. This study assessed the impact of a social communication intervention on teacher perceptions of social withdrawal in children who received the treatment. The intervention targeted emotion understanding using the presentation of children's stories, facial picture cards, and journaling. Teacher perception was measured using the three withdrawal subscales of the Teacher Behavior Rating Scale (TBRS): Solitary-Active withdrawal, Solitary-Passive withdrawal, and Reticence. Following treatment all five participants received lower ratings of withdrawn behavior on some of the subscales. Only one participant received a rating indicting increased …

Children's Adaptation To Electropalatography: Evidence From Acoustic Analysis Of /T/ And /K/, Kara Brianne Knapp

Theses and Dissertations

Electropalatography (EPG) is a computer-based device that uses a fitted pseudopalate (similar to an orthodontic retainer) with embedded electrodes to track tongue-to-palate contact during speech for the purposes of providing treatment for a variety of communication disorders. This study evaluated six elementary school-aged children's ability to adapt their speech to the presence of the pseudopalate in their mouth. The participants' adaptation for the consonants /t/ and /k/ was examined over eight time intervals throughout a two and half hour time period. Adaptation was evaluated by measuring the duration, spectral mean, spectral variance, and relative intensity of the target sounds. The …

A Model Of Grammatical Category Acquisition Using Adaptation And Selection, Sarah Zitting Cluff

Theses and Dissertations

By the later preschool years, most children have a knowledge of the grammatical categories of their native language and are capable of expanding this knowledge to novel words. To model this accomplishment, researchers have created a variety of explicit, testable models or algorithms. These have had partial but promising success in extracting grammatical word categories from transcriptions of caregiver input to young children. Additional insight into children's learning of the grammatical categories of words might be gained from evolutionary computing algorithms, which apply principles of evolutionary biology such as variation, adaptive change, self-regulation, and inheritance to computational models. The current …

Otoscopic And Tympanometric Outcomes In Haitian Children, Ellen May

Dissertations, Theses, and Capstone Projects

Outer and middle ear pathologies are common and highly treatable conditions that affect children worldwide. While data on the prevalence of outer and middle ear disorders in children in North America and other developed countries is ample, such data in developing countries is oftentimes scarce. Determining the prevalence of outer and middle ear disorders is vital, as these types of disorders, if left untreated, can have medical, audiological, and educational implications. Both the identification and treatment of outer and middle ear pathologies are especially important in Haiti, a country that has a severe lack of medical resources, and is especially …

Benefit And Quality Of Life Improvement In Older Adult Cochlear Implant Recipients: A Review Of The Literature, Theresa Bartoldus

Dissertations, Theses, and Capstone Projects

The aging population is increasing rapidly, and in this group hearing loss is one of the most common disabilities. For those with severe to profound impairment, which occurs in approximately 10% of this population, conventional amplification often fails to provide adequate benefit. In these cases, a cochlear implant is indicated. The literature on cochlear implantation in older adults has shown that it offers significant speech perception and quality of life benefits to this population. However, it remains controversial despite ample research demonstrating these benefits, due to concerns about surgical complications and reduced benefit due to aging processes. Much literature also …

A Review Of Animal Studies For The Efficacy Of D-Methionine In Reducing Threshold Shifts And Affecting Biochemical Changes After Exposure To Noise, Alexandra Petraru

Speech Adaptation To Electropalatography In Children's Productions Of /S/ And /ʃ/, Marissa Celaya

Theses and Dissertations

Previous research has investigated adults' ability to adapt their speech when a electropalatographic (EPG) pseudopalate is placed in the oral cavity; however, less is known about how younger speakers who are continuing to develop their motor speech abilities might adapt their speech to the presence of the device. This study examined the effect of an EPG pseudopalate on elementary school-aged children's ability to produce the fricatives /s/ and /ƒ/. Audio recordings of six children were collected at eight time intervals including before placement of the pseudopalate, at 30-minute increments for two hours with the pseudopalate in place, immediately following removal …

The Salience And Perceptual Weight Of Secondary Acoustic Cues For Fricative Identification In Normal Hearing Adults, Derek Petti

Dissertations, Theses, and Capstone Projects

The primary cue used by normal hearing individuals for identification of the fricatives /s/ and /ʃ/ is the most prominent spectrum of frication, which is discrete for this fricative contrast. Secondary cues that influence the identification and discrimination of these fricatives are context dependent. Specifically, the secondary cues that have been found to most significantly impact fricative perception include (a) the second formant transition onset and offset frequencies of a fricative-vowel pair, and (b) the amplitude of the spectral peak in the 2500Hz region of frication relative to an adjacent vowel’s peak amplitude in the same frequency region. However, the …

Reflective Practice And Professional Knowledge: A Grounded Theory Study Of Speech-Language Pathologists Working In Head And Neck Cancer Rehabilitation, Marie-Eve Caty

Electronic Thesis and Dissertation Repository

Reflective practice is defined in this dissertation as a process of thinking 'about' and 'through' one's doings, such that practitioners become more skillful, and aware of the nature and impact of their performance within their professional practices. Because it is presumed to enable healthcare delivery practices that are more sensitive to patient needs and more in-line with evidence- based practices, RP is frequently noted as an essential attribute of competent clinical practice. Yet, little is known about the processes by which RP contributes to the professional learning of health-care practitioners in general, and Speech- Language Pathologists (SLPs) in particular.

Effect Of Retrieval Practice On Applied Knowledge: Evidence From A Professional Training Program, Jenna Voss

Arts & Sciences Electronic Theses and Dissertations

A primary goal of deaf education teacher preparation programs is to help students acquire a sufficient body of factual and pedagogical knowledge and retain it for future application while serving children with hearing loss and their families. One potential way to improve teacher preparation is through the implementation of retrieval practice, a strategy to promote learning and retention of material over time. This study examined whether retrieval practice could be used to improve learning in an authentic educational environment, using real content, and real materials. While this study provided important information regarding the implementation of retrieval practice authentic classrooms, it …

Effects Of Auditory And Visual Distracters On Acceptable Background Noise Level In Hearing-Impaired Listeners, Elizabeth A. Ripley

Dissertations, 2014-2019

Acceptable Noise Level (ANL), is an established procedure for determining the amount of background noise a listener is willing to accept while listening to speech. ANL is established by having the listener select most amount of background noise they are willing to accept while listening to a speech stimulus presented at their most comfortable listening level (MCL). While ANLs have been established as good predictors of hearing aid use, little is known on how hearing aid users accept background noise while engaged in cognitively demanding tasks. Previous research in normal hearing listeners has demonstrated that listeners will allow the most …

The Neural Representation And Behavioral Detection Of Frequency Modulation, Daniel Elliott Shearer

Dissertations, 2014-2019

Understanding a speech signal is reliant on the ability of the auditory system to accurately encode rapidly changing spectral and temporal cues over time. Evidence from behavioral studies in humans suggests that relatively poor temporal fine structure (TFS) encoding ability is correlated with poorer performance on speech understanding tasks in quiet and in noise. Electroencephalography, including measurement of the frequency-following response, has been used to assess the human central auditory nervous system’s ability to encode temporal patterns in steady-state and dynamic tonal stimuli and short syllables. To date, the FFR has been used to investigate the accuracy of phase-locked auditory …
