Brain Mapping Of The Mismatch Negativity Response In Vowel Formant Processing, Elizabeth Anne Perry

Theses and Dissertations

The mismatch negativity (MMN) response, a passively-elicited component of the auditory event-related potential (ERP), reflects preattentive identification of infrequent changes in acoustic stimuli. In the current study, the MMN response was examined closely to determine what extent natural speech sounds evoke the MMN. It was hypothesized that a significant MMN response results during the presentation of deviant stimuli from which spectral energy within formant bands critical to vowel identification has been removed. Localizations of dipoles within the cortex were hypothesized to yield information pertaining to the processing of formant-specific linguistic information. A same/different discrimination task was administered to 20 adult …

Intelligibility And The Sinewave Speech Carrier Phrase Effect, Danielle R. Werle

Honors Theses

Several studies have examined the perception of sinewave speech. Early work showed that listeners could transcribe sinewave sentences. Recent work on sinewave vowels found that listeners could recognize sinewave speech at the phonetic level with moderate (about 50-55%) accuracy. Sinewave vowel intelligibility scores improve significantly when preceded by a sinewave carrier phrase, an effect that disappears when the carrier phrase is removed. The present study was designed to examine this carrier phrase enhancement effect and analyze whether listeners require the carrier phrase to be intelligible to produce increased intelligibility scores. Sinusoidal carrier phrases and /hVd/ syllables were generated from recordings …

Perceived Occlusion And Comfort In Receiver-In-The-Ear Hearing Aids, Sara A. Conrad

Dissertations, 2014-2019

Purpose: In this study participants rated self-perceived occlusion and physical comfort for receiver-in-the-ear (RITE) hearing aids with different sizes of standard domes. Perceived occlusion was rated across listening and own voice conditions. Method: Twenty-one older adults with hearing impairment were fitted with bilateral RITE hearing aids and tested with three dome size conditions: open, plus, and power domes, and one control condition: the participants' own aids. Participants ranked self-perceived occlusion across the dome size conditions as well as across listening and own voice conditions, and also ranked level of physical comfort across dome sizes. Results: Self-perceived occlusion increased as dome …

Headturn Preference Of 10-Month Infants For Familiar And Unfamiliar Signs, Steven Thomas Kulsar

Dissertations, 2014-2019

Most deaf babies born in the United States are born into hearing families and show a developmental lag in spoken language acquisition, reading, writing, and social development when compared to deaf babies of deaf parents or hearing babies of hearing parents, due to limited language access. A modified headturn paradigm has been devised to assess infant preference to various familiar and unfamiliar ASL stimuli, to determine parallels between auditory-spoken and visual-spatial languages. If visual perception of first signs parallels auditory perception of first words, we would expect infants exposed to ASL as their native language to show a preference for …

A Comparison Of Vibrotactile And Air Puff Stimulation For Inducing Swallowing, Kathryn Diane White

Dissertations, 2014-2019

The purpose of this study was to evaluate the effectiveness of two types of non-invasive, sensory stimulation on increasing the rate of swallowing and for inducing cortical activity associated with swallowing. The types of stimulation investigated were vibrotactile stimulation to the external throat area surrounding the laryngeal tissues and oral air puff stimulation to the anterior faucial pillars. A functional near infrared spectroscopy (fNIRS) system measured relative changes in the concentration of oxygenated hemoglobin (HbO) in cortical sensorimotor regions as an indirect measure of brain activity. The experiment included 16 healthy adult participants between the ages of 28 and 60 …

The Effects Of Age On The Mismatch Negativity Response To Differences In Place Of Articulation, Meredith Robotti

Dissertations, 2014-2019

The Mismatch negativity (MMN) response measures the auditory system’s response to change in stimulus. This measurement can be used to identify if the auditory system can physiologically discriminate two speech sounds. To date, studies that have recorded MMNs in response to differing place of articulation show conflicting data. One possibility for the conflicting results is due to the lack of carefully controlled stimuli. The purpose of this study was to evaluate the differences in amplitude and latency between adult and infant MMN responses when manipulating place of articulation for speech. Additionally, this study sought to determine if all adults showed …

Normal And Mutant Murine Auditory Brainstem Responses (Abrs), Kristin Shearer

Dissertations, 2014-2019

Spatial organization and topographic maps begin in the periphery and are preserved throughout the central auditory system. The Eph and ephrin family of signaling proteins is involved in the patterning and arrangement of auditory afferents which code information about frequency, intensity, and time. The present study utilizes the ABR as a physiological measure of the electrical potentials occurring in the brainstem following acoustic stimulation. We recorded this measure following click and tone pip stimulation in ephrin-B3 and EphA4 deficient mice at 2-3 months of age and compared them to wild type controls. Significant findings included elevated auditory thresholds, prolonged latency …

Do Different Methods Of Hearing Aid Information Delivery Influence Knowledge Acquisition?, Lindsey Ann Parr

Dissertations, 2014-2019

The main purposes of this study were to examine whether or not there was a difference in knowledge acquisition as a function of training method (these included: face-to-face session, DVD, and pamphlet); to determine which information included in hearing aid orientation was commonly known prior to training and which showed the most learning after training; and to evaluate which training method is the most popular among participants. A sample of 65 young college students with no prior hearing aid experience completed a pre- and post-multiple-choice test of hearing aid knowledge and gave their opinion of the hearing aid orientation immediately …

Investigating Motor Training In People Who Stutter Using Fnirs, Kristen Michelle Johnson

Masters Theses, 2010-2019

This pilot study investigated motor learning and neuroplasticity in persons who do and do not stutter before and after participation in a phonation onset training protocol. Outcomes included phonation onset time and percent change in oxygenation level of hemoglobin using fNIRS in prescribed brain areas as a result of training. The authors hypothesized that people who stutter (PWS) would 1) exhibit a breakdown in auditory perception to motor production interactions, 2) demonstrate a difference in the way in which they perceive and learn motor information compared to someone who does not stutter (nPWS), and 3) exhibit reduced brain activity correlations …

Pushing To The Breaking Point: Do Children With Speech And Language Problems Experience Bullying?, Meagan D. Pestel

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The purpose of this study was to examine if students with speech and/or language disorders were more likely to experience bullying than children with normal developmental milestones and speech. There were fifty parents sought to respond to a survey (by using Survey Monkey) about their child’s specific disorder, school size, age, bullying experiences, etc. Twenty-two responses were obtained for research. Results of the research showed that about 50% of parents felt their child had been bullied because of their speech and/or language problem while 50% of parents felt that their child was not bullied or the bullying they experienced was …

Building Interaction With An Isolated Population Through Social Media: The Deaf Community, Margaret Bodemann

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The purpose of the study is to discover the effects of social media on the deaf community. Ten individuals, aged from 21 to 29, participated in this study. There was no control for race, ethnicity, or socioeconomic status. An Internet survey was used to gather data. Results suggest that hearing impaired individuals do use social media and that the ways in which is it used varies as a function of degree of hearing loss.

Cochlear Implants: How Siblings Are Changed, Callie Wilson

Neurophysiologic Investigation Of The Auditory What And Where Pathways In Young And Middle-Aged Adults, Ann Marie Olson

Theses, Dissertations and Culminating Projects

When a sound is heard, individuals intrinsically attempt to identify the sound and its location. This automatic and parallel processing is known as the auditory “what” and “where” pathways. The present study involved the neurophysiologic investigation of the auditory dual pathways in an attention and working memory task as a function of age. Using identical stimuli, event-related potentials were measured in young and middle-aged adults with normal hearing for both pitch identification (“what” pathway) and location (“where” pathway). Results showed differences in cortical processing of the “what” and “where” pathways as a function of age and task instruction. Although processing …
