Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …

Comparing Spoken Language Treatments For Minimally Verbal Preschoolers With Autism Spectrum Disorders, Rhea Paul, Daniel Campbell, Kimberly Gilbert, Ioanna Tsiouri

Communication Disorders Faculty Publications

Preschoolers with severe autism and minimal speech were assigned either a discrete trial or a naturalistic language treatment, and parents of all participants also received parent responsiveness training. After 12 weeks, both groups showed comparable improvement in number of spoken words produced, on average. Approximately half the children in each group achieved benchmarks for the first stage of functional spoken language development, as defined by Tager-Flusberg et al. (J Speech Lang Hear Res, 52: 643–652, 2009). Analyses of moderators of treatment suggest that joint attention moderates response to both treatments, and children with better receptive language pre-treatment do better with …

Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten

Theses and Dissertations--Communication Sciences and Disorders

This study investigated the accuracy of healthy aging adults‟ self-rating of communication style, as measured by quantifiable measures of discourse performance. Ninety cognitively healthy adults participated and comprised three age cohorts (20s, 40s, 60s). Participants completed discourse tasks that included recounting a vacation, telling a story, and describing a picture. Participants also self-rated their communication style, placing them in a talkative or reserved cohort. Communication style was measured by discourse performance variables of interest: length of output (TNW) and informativeness (%IU). When presented with an unconstrained task (recounting a vacation), talkative and reserved groups, regardless of age, produced a similar …

Experiences Of Speech-Language Pathology Graduate Students: An Exploratory Phenomenological Study, Anysia J. Ensslen

Theses and Dissertations--Educational Leadership Studies

Within the past decade little research has been conducted in the United States to examine the preparedness of beginning speech-language pathologists; the seminal article used for this research study comes from the United Kingdom (Horton, Byng, Bunning, & Pring, 2004). Literature from the past few decades indicates that there may be deficiencies in the way that beginning speech-language pathologists are being trained clinically.

The review of the literature suggests that the field may lack a clear and broadly supported learning theory or framework for the clinical supervision and training of speech-language pathology graduate students. The literature further supports the importance …

Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes

Open Access Theses

The production of speech prosody (the rhythm, pausing, and intonation associated with natural speech) is critical to effective communication. The current study investigated the impact of age-related changes to physiology and cognition in relation to the production of two types of linguistic prosody: lexical stress and the disambiguation of syntactically ambiguous utterances. Analyses of the acoustic correlates of stress: speech intensity (or sound-pressure level; SPL), fundamental frequency (F0), key word/phrase duration, and pause duration revealed that both young and older adults effectively use these acoustic features to signal linguistic prosody, although the relative weighting of cues differed by group. Differences …

Purpose: The purpose of this project was to investigate the possible relation between standardized measures of vocabulary/language, mother and father education, and a composite measure of socioeconomic status (SES) for children who do not stutter (CWNS) and children who stutter (CWS).

Methods: Participants were 138 CWNS and 159 CWS between the ages of 2;6 and 6;3 and their families. The Hollingshead Four Factor Index of Social Position (i.e., Family SES) was used to calculate SES based on a composite score consisting of weighted values for paternal and maternal education and occupation. Statistical regression analyses were conducted to investigate the relation …

Common Parietal Activation In Musical Mental Transformations Across Pitch And Time, Nicholas E.V. Foster, Andrea Halpern, Robert J. Zatorre

Faculty Journal Articles

We previously observed that mental manipulation of the pitch level or temporal organization of melodies results in functional activation in the human intraparietal sulcus (IPS), a region also associated with visuospatial transformation and numerical calculation. Two outstanding questions about these musical transformations are whether pitch and time depend on separate or common processing in IPS, and whether IPS recruitment in melodic tasks varies depending upon the degree of transformation required (as it does in mental rotation). In the present study we sought to answer these questions by applying functional magnetic resonance imaging while musicians performed closely matched mental transposition (pitch …

Analysing A New Mobile Bilateral Audiology Test For Children, Luke J. Brook

Theses : Honours

Hearing loss in Australian children, primarily Aboriginal and Torres Strait Islanders, is a growing concern for the Australian public health sector. In certain rural communities up to 90 per cent of children have been found to experience some form of hearing loss. Although hearing loss can be the result of a number of different causes, including congenital influences, the most common cause of hearing loss in Australian children is attributed to a common middle ear infection, otitis media.

To address the issue, numerous solutions have been proposed, tested and implemented, although the problem persists due to geographic, environmental and cultural …

Women Who Stutter : Experiences Of Developing Self-Management And Quality Of Life, Katherine Milton

Theses : Honours

Background and Purpose: Research suggests that stuttering can impact an individual’s quality of life and how they perceive themselves in interactions with others. As a larger proportion of adults who stutter are men, limited research is available regarding the specific experiences of women who stutter (WWS). Existent literature regarding WWS was mainly published in the 1970s -1980s and may no longer represent current issues. This study aimed to explore the current influences on quality of life, perception of stuttering, self-management strategies, and gender issues experienced by WWS.

Methods and Procedures: This grounded theory study used a convenience sample of eight …

The Use Of The Communication Checklist - Adult (Cc-A) For Assessing The Communication Abilities Of Individuals Post Traumatic Brain Injury, David B. Fitzgerald

Theses : Honours

Background and aims: Standardised and non-standardised assessments are used in speech pathology to evaluate an individual’s communication abilities post traumatic brain injury (TBI; e.g. Turkstra et al., 2005b). However, valid, reliable and norm-referenced standardised assessments that examine functional communication abilities of individuals post TBI outside of the clinical environment are limited. This study sought to investigate the validity of the Communication Checklist - Adults (CC-A; Whitehouse & Bishop, 2009), a caregiver questionnaire that assesses the communication abilities of individuals post TBI.

Method: The project recruited 14 participants post TBI with varying communicative impairment severities. Each participant completed a routine communication …

Examining Articulatory Kinematics Using Diadochokinesis In Concussed And Non-Concussed Individuals, Lindsay Deann Dolan

Open Access Theses & Dissertations

ABSTRACT

Cognitive and communicative deficits associated with traumatic brain injury are an active area of research. However, no research to date has reported on the functionality of motor speech following a concussion. A common tool used to evaluate the motor speech status of potentially impaired individuals is the measurement of the diadochokinetic speech rate. The purpose of this study is to investigate diadochokinetic speech rates in individuals who experience a sports-related concussion. Determining the nature and extent of motor speech involvement post concussion will contribute to the diagnosis, prognosis, and management of recovery. The present investigation will determine; (i) if …

The participant for this study was a verbal eleven-year male, who was diagnosed with autism prior to the study. A single subject alternating treatment research design was used to evaluate the effect of a high-tech speech generating AAC device (Proloquo2go) on echolalia. The participant was seen periodically twice a week for two months and periodically for one month. A functional analysis(Prizant & Rydell, …

Bilingual Adult Nonword Repetition Performance Patterns In English And Spanish, Gabriela Villaneda

Open Access Theses & Dissertations

Nonword repetition (NWR) is known to assess phonological working memory. During NWR, the individual listens to made-up words and repeats them back. This study evaluated NWR performance patterns, and the relationship between NWR and language recall tasks among forty English and Spanish bilingual adults. Bilingual adults' ages ranged from 18-67 years. Four language recall tasks were administered, including NWR tasks (assessed by PPC), language questionnaire to assess participants' language usage in English and Spanish, sentence repetition task (assessed by raw score), and a story retell (assessed by NDW). All recall measures were administered in a counterbalanced manner across English and …
