When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

Clinical Implications Of Binaural Interference: A Systematic Review Of The Literature, Michael Bergen

Dissertations, Theses, and Capstone Projects

A binaural advantage has been described in many studies over the past fifty years, although research also has demonstrated examples of a disadvantage known as binaural interference. The literature varies greatly in suggesting the incidence of binaural interference across all populations. It also raises questions about the underlying causes of this phenomenon, as well as whether age-related changes have an impact.

A systematic review was engaged to summarize the literature associated with binaural interference, to identify clinical implications of this body of literature, and to answer two research questions:

1) Does the literature describe changes in susceptibility to binaural interference …

Underprivileged Children In Port-Au-Prince, Haiti: Hearing And Academic Performance Of Children In Public Schools In Port Au Prince, Talia Meisel

Dissertations, Theses, and Capstone Projects

Hearing loss is estimated to affect more than 360 million people worldwide, 32% of whom are children. Children with hearing loss tend to develop compromised communicative abilities and also have been found to perform more poorly academically than their normal hearing peers. Because of the lack of medical care, children in third world countries are expected to have more difficulty hearing and learning in a classroom setting than children in first world countries due to higher incidences of conductive pathology. The purpose of this study is to assess the hearing ability of underprivileged children in kindergarten and primary schools in …

The Status Of Neonatal Hearing Screening In Sub-Saharan Africa: A Systematic Review, David Engelman

Dissertations, Theses, and Capstone Projects

Late identification of hearing loss can lead to speech and language delays, as well as social and academic difficulties. Neonatal hearing screening has reduced the age of identification of hearing loss in many developed countries. However, the practice is limited or non-existent in much of the developing world, such as sub-Saharan Africa. This systematic review used currently available literature to determine the status of neonatal hearing screening programs in sub-Saharan Africa and to develop a model program for the region. Results suggested a lack of neonatal hearing screening services in sub-Saharan Africa, stressing the need for more pilot hearing screening …

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

Dissertations, Theses, and Capstone Projects

Noise induced hearing loss (NIHL) is a major public health concern in the United States and worldwide. Certain individuals such as factory workers and military personnel are at greatest risk for irreversible sensorineural hearing loss due to the limitations of hearing protection measures and devices. D-Methionine (d-Met) is an antioxidant otoprotective agent that currently is in human clinical trials. The purpose of this systematic literature review was to review d-Met’s efficacy in reducing threshold shifts as well as in producing biochemical and physical changes in animal studies vis-à-vis the administration paradigm (preloading, rescue and a combined approach), d-Met dose quantity …

Attitudes Of Speech-Language Pathology/Audiology Students Towards Noise In Youth Culture, Lillian Law

Dissertations, Theses, and Capstone Projects

In order to increase the use of hearing conservation strategies among youth, it is important to identify which populations are most amenable to potential behavior change. The purpose of the present study was to compare attitudes towards noise between undergraduate speech-language pathology/audiology majors and other majors. Participants (N = 119) responded to a survey used to compare attitudes toward noise in the two groups, as well as their perceived ability to influence their sound environment. In addition, a correlational analysis was performed to determine if a relation exists between attitudes towards noise and attitudes towards influencing one's sound environment. Findings …

Efficacy Of N-Acetylcysteine On Prevention And Amelioration Of Cisplatin-Induced Ototoxicity: A Systematic Literature Review, Maryana Peravozchykava

Dissertations, Theses, and Capstone Projects

Objective: The purpose of this investigation is to perform a systematic review of the existing literature on NAC efficacy in prevention of cisplatin-induced ototoxicity.

Methods: A comprehensive search utilizing databases via the Mina Rees Library of the Graduate Center of the City University of New York was conducted to identify relevant studies for analysis. The levels of evidence were applied to restrict articles reviewed to Level 3 or better.

Results: Eight articles evaluating NAC protective efficacy against cisplatin-induced ototoxicity were identified. The results revealed significant variability in NAC otoprotective efficacy.

Discussion: The significant variability in findings on NAC otoprotective efficacy …

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 …

Neurophysiological Bases Of Frequency Discrimination In Children With Auditory Processing Disorder Or Specific Language Impairment, Christine Rota-Donahue

Dissertations, Theses, and Capstone Projects

The purpose of this study was to determine if 10-12 year old children with Auditory Processing Disorder (APD) or Specific Language Impairment (SLI) could discriminate three different frequency changes behaviorally and electrophysiologically. Behavioral frequency discrimination and event-related potentials were examined using a 1000Hz pure tone base frequency. Typically developing children and children with APD or SLI differed in in their detection of frequency changes: behavioral results were below chance level and the MMN amplitude was smaller in the impaired population. Slight differences between children with APD and children with SLI were also found that might shed light on the controversy …
