Vestibular Correlates Of Cochlear Implantation, Danielle Lewis

Dissertations, Theses, and Capstone Projects

Previous research has illustrated that vestibular dysfunction is the most prevalent complication of cochlear implant (CI) surgery. There is substantial evidence of both short- and long-term vestibular dysfunction following CI surgery. The objective of this survey was to determine CI recipients’ expectation and satisfaction with their audiologists’ counseling regarding the possible vestibular effects of cochlear implantation. Survey participants included unilateral and bilateral adult CI recipients recruited through the NYC chapter of the Hearing Loss Association of America (HLAA), audiology-related Facebook groups, and Linked-In. The first 25 participants were offered a $20 Amazon gift card upon completion of the survey. The …

A Survey Of Cochlear Implant Clinical Protocols In India, Ariana Morris

Dissertations, 2020-current

The most recent data published in December 2019 records that approximately 736,900 registered cochlear implantation devices have been received since their approval in the 1980s. While 183,100 of these devices belong to U.S. Citizens, the large majority of cochlear implant recipients live in other countries (U.S. Department of Health and Human Services, 2016). While a lack of standardized practices exists in relation to audiologic care and management of cochlear implant devices and patients, Browning et al. (2020) attempts to assess and analyze common practices amongst audiologists practicing within the United States of America. This survey uses a modified questionnaire based …

The Effects Of Cochlear Implantation And Educational Audiology Services On Language Skills: A Case Study, Madison Josey

Honors Theses

Purpose

Hearing loss can affect many aspects of a child’s life, particularly their language abilities and academic performance. Literature shows that children with hearing loss are more likely to have language deficits compared to their hearing peers (Tomblin et al., 2015). The degree to which language skills are affected has been shown to correlate with various factors, such as age of identification, hearing levels, and amount of speech and language intervention (Delage & Tuller, 2020; Shojaei et al., 2016). The aim of this research study was to assess how cochlear implantation and speech-language intervention affects the language skills and academic …

Expressive Vocabulary Development In Very Young Children Who Are Deaf Or Hard Of Hearing, Amanda Mcnamara Rudge

Arts & Sciences Electronic Theses and Dissertations

This longitudinal study aimed to explore the expressive vocabulary growth rate of children ages birth to three years, who are deaf or hard of hearing (d/hh). An additional aim was to investigate hours of direct instruction received during early intervention as a factor that may contribute to the trajectories of expressive vocabulary growth in young children who are d/hh. Hierarchical linear modeling with growth curve analysis was used to investigate expressive vocabulary growth in a population of d/hh children using multiple points of longitudinal vocabulary data. A total of 417 assessments across the 105 participants were analyzed to determine the …

Music And Speech Perception In Pre-Lingually Deafened Young Listeners With Cochlear Implants: A Preliminary Study Using Sung Speech, Harley J. Wheeler

Dissertations, 2020-current

Timbre and pitch cues, though definitionally and physically distinct characteristics of sound, are attributes of all sound signals. A body of literature has shown that alteration of one characteristic can influence the perception of the other; e.g., speech spoken with an atypical contour of pitch can influence a listener's accuracy in identifying the words spoken; conversely, whether a melodic contour is presented via a MIDI piano representation or as sung speech can influence the accuracy of identification of the pitches' contour. Trends for these interactions have been documented for normal hearing children and adults, as well as postlingually deafened adult …

Audiologists’ Preferences In Programming Cochlear Implants, Leanne Browning

Dissertations, 2014-2019

Cochlear implants have become a viable option for those with severe to profound sensorineural hearing loss who gain little benefit from hearing aids and have poor word recognition ability. However, the techniques audiologists use to program these devices are not standardized (Sorkin, 2013). There is little data available which analyzes how audiologists handle clinical cochlear implant programming between the top manufacturers. These companies supply default settings in their products but is it unknown how often audiologists use these in practice in the United States.

In the present study, a questionnaire based on previous European data from Vaerenberg et al. (2014) …

Exploring The Cochlear Implant Controversy: The Role Of And Experience With Deaf Culture For Parents Of Pediatric Cochlear Implant Users, Tia Kilgore

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

This project examined the relationships between pediatric cochlear implantation and Deaf Culture. More specifically, this research investigated how/if parents are educated about or exposed to Deaf Culture during the cochlear implant candidacy evaluation process, and what type of interactions (if any) the child or caregiver had with members of the Deaf community after the child received a cochlear implant. A short survey was distributed to caregivers of pediatric cochlear implantees. While the responses were varied, a majority of caregivers responded that Deaf culture was not an active piece of the CI candidacy process. Additionally, interactions with members of the Deaf …

An Overwhelming Journey: Mothers Of Children Cochlear Implant Users Experiences With Speech-Language Pathologists, Jennifer Beebe

Master's Theses and Doctoral Dissertations

This study shares themes identified across the experiences of mothers of children cochlear implant users with speech-language pathologists. Parents describe learning that their child has a hearing loss as an overwhelming journey with much to learn and many decisions to make, especially in their child’s first year of life. Parents rely on professional support in developing their child’s listening and spoken language development. A phenomenological framework of qualitative research was utilized to understand the perspective of the mothers who participated in this study. The intent of this study is to improve the partnership between parents and professionals of children with …

Assessing Cognitive Abilities In High-Performing Cochlear Implant Users., Jake Hillyer, Elizabeth Elkins, Chantel Hazlewood, Stacey D Watson, Julie G Arenberg, Alexandra Parbery-Clark

Articles, Abstracts, and Reports

Despite being considered one of the most successful neural prostheses, cochlear implants (CIs) provide recipients with a wide range of speech perception performance. While some CI users can understand speech in the absence of visual cues, other recipients exhibit more limited speech perception. Cognitive skills have been documented as a contributor to complex auditory processing, such as language understanding; however, there are no normative data for existing standardized clinical tests assessing cognitive abilities in CI users. Here, we assess the impact of modality of presentation (i.e., auditory-visual versus visual) for the administration of working memory tests in high-performing CI users …

Spontaneous Vocal Matching In Mothers And Their Hearing Impaired Infants With Cochlear Implants : A Quantitative Analysis., Lydia Doggett

Electronic Theses and Dissertations

Vocal matching, the ability to imitate phonetic properties of speech, was examined in spontaneous interactions of sixteen dyads of mothers and their hearing-impaired (HI) infants with cochlear implants and age-matched normal-hearing (NH) infants. Mother-infant dyads came to three sessions at three, six, and 12 months post-implantation. Vocal matching was defined as an instance of perceptual and acoustic similarity of vowels and consonants between adjacent maternal and infant utterances. Vocal matching occurred in 25% to 50% of infant and in 17% to 64% of mother vocalizations across dyads. Both mothers and infants in the HI group produced fewer matches as compared …

Social Support, Social Companionship, And Social Distress In Young Adults With Cochlear Implants, Arta Ljubanovic

Dissertations, Theses, and Capstone Projects

Research has shown that social support has a positive impact on mental health and decreases levels of stress in young adults with normal-hearing sensitivity. Social relationships are one psychological construct that has not been previously studied in young adults with cochlear implants. In light of the importance of social support in the overall well-being of an individual and the lack of research on this topic in individuals with cochlear implants, the study purpose is to examine social relationships in young adults with cochlear implants and to determine the presence of any significant differences in social relationships between the group with …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

Development Of Rhyming Tasks In Preschool Aged Children With Hearing Loss, Kaylie Mcnally, Mary Katherine Connelly

Undergraduate Research

1) the degree of hearing loss , and 2) listening device type. Results showed no significant difference in rhyming skills in relation to either condition.

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 …

A Model For Electrical Communication Between Cochlear Implants And The Brain, Douglas A. Miller

Electronic Theses and Dissertations

In the last thirty years, cochlear implants have become an invaluable instrument in the treatment of severe-to-profound hearing impairment. An important aspect of research in the continued development of cochlear implants is the in vivo assessment of signal processing algorithms intended to improve perception of speech and other auditory signals. In trying to determine how closely cochlear implant recipients process sound relative to the processing done by a normal auditory system, various assessment techniques have been applied. The most common technique has been measurement of auditory evoked potentials (AEPs), which involves the recording of neural responses to auditory stimulation. Depending …
