Cognitive And Neurobiological Degeneration Of The Mental Lexicon In Primary Progressive Aphasia, Jet M. J. Vonk

Dissertations, Theses, and Capstone Projects

The ease with which we use the thousands of words in our vocabulary stands in stark contrast to our difficulty establishing how they are organized in our mind and brain. The breakdown of language due to cortical atrophy in primary progressive aphasia (PPA) creates conditions to study this organization at a cognitive and neurobiological level in that the three variants of this disease, namely non-fluent, logopenic, and semantic PPA, each bear their own signature of language-specific decline and cortical atrophy. As the impaired regions in each variant are linked to different lexical and semantic attributes of words, lexical decision performance …

Music Perception Performance In Prelingually Deafened Children With Cochlear Implants Pre And Post Structured Music Training Postoperative Habilitation Programs: A Systematic Review, Jessica K. Woodson

Dissertations, Theses, and Capstone Projects

The goal of this project was to systematically review literature in order to analyze music perception performance in prelingually deafened children with cochlear implants before and after structured music training postoperative habilitation programs. Features of music which were evaluated included pitch, melody, timbre, rhythm, and appraisal. In six studies, these measures of music perception were compared pre and post formal music training; in one study, music perception performance was compared between prelingually deafened cochlear implant users and individuals with normal-hearing sensitivity. Overall, when the music training was sufficiently long, the findings indicated that music training significantly improves pitch perception ability. …

The objective of the current study was to examine, in a retrospective case series, outcome in terms of word-recognition performance in patients with neurofibromatosis Type 2 (NF2) who have received a cochlear implant (CI) The primary independent variables were duration of deafness (DoD) and age at cochlear implantation. The secondary independent variables were status of hearing sensitivity in the ear contralateral to the one that received cochlear implantation and the type of tumor treatment.

The retrospective case series comprised eight patients who were implanted at New York University Medical Center, or who were receiving follow-up care there. All NF2 patients …

Hearing Related Concerns Among Parkinson’S Patients And Their Care Partners, Samantha Morgan

Dissertations, Theses, and Capstone Projects

The goal of this study is to evaluate the relationship between self-reported subjective hearing loss and objective measures of hearing in older adults with Parkinson’s Disease (PD), as well as the relationship between self-reported hearing handicap of those with PD and the report of their care partners. Twenty-four individuals, comprised of older adults with PD and their primary care partners, underwent subjective and objective hearing screenings and completed measures of self-reported hearing handicap. Results revealed no significant relationship between the subjective and objective hearing screening results of those with PD, nor any significant relationship between the self-report of hearing handicap …

A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein

Dissertations, Theses, and Capstone Projects

The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels and …

Methods And Professionals Involved In Evaluating Postural Control In The Autism Spectrum Disorder Population: A Systematic Review, Christina Melora

Dissertations, Theses, and Capstone Projects

The objective of this systematic review was to determine the methods in which postural stability and control are being quantified in persons with Autism Spectrum Disorder (ASD), with what instrumentation and which healthcare professionals are included in this process. It is well studied that persons with Autism Spectrum Disorder (ASD), which now include those with Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) and Asperger Disorder, often suffer from vestibular modulation abnormalities (Rogers & Ozonoff, 2005; American Psychiatric Association, 2013.) These individuals may present with either an under- or over-responsiveness to vestibular inputs resulting in a variety of repetitive behaviors or …

"Marie Manje La Pom Nan." Examining The Cognitive Process Of Restructuring And Advantage Selection In The Definite Article System In Haitian Creole Among U.S. Born Heritage Speakers Of Haitian Creole, Marie-Michelle Monéreau-Merry

Dissertations, Theses, and Capstone Projects

The distributional patterns of heritage speakers’ reanalyzed first language are often grammatically divergent from native speakers. Irrespective of the heritage language, there is converging evidence that the cognitive process of reanalysis of heritage languages is often evident in less salient properties of the language, such as inflectional morphology (Polinsky & Kagan, 2007). Therefore, Haitian Creole (HC) is a candidate for restructuring. In this investigation we compared the morphophonological patterns of the definite article system at the production and perception level between two groups of early learners of Haitian Creole (i.e. native speakers vs. United States (US) born heritage speakers).

Development Of 90th Percentile Norms For Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study, Iris Wertheimer

Dissertations, Theses, and Capstone Projects

The acoustic reflex threshold has been well established in the literature as an involuntary bilateral contraction of the stapedius muscle in response to loud transient sounds. Additionally, the clinical utility of the acoustic reflex threshold has been established as it allows for the differential diagnosis of many different conductive, cochlear and retrocochlear pathologies. Gelfand, Schwander and Silman (1990) have established and validated 90^th percentile normative data for use with the contralateral acoustic reflex threshold. Much of the literature on the acoustic reflex threshold has focused on the contralateral acoustic reflex threshold; however, surveys have found that many clinicians are …

Affordable And Accessible Hearing Healthcare Interventions In The United States: A Literature Review And Prospective Analysis, Garrett Thompson

Dissertations, Theses, and Capstone Projects

Age-related hearing loss is a significant public health concern with serious and far-reaching consequences including: social isolation, depression, faster cognitive decline, and increased risk of falls. Hearing loss is a widespread condition, it is in fact a leading cause of disability among older people. Hearing aids, the primary intervention for adults with hearing loss, are costly and inaccessible to many patients who need them. Among other reasons, these factors have led to a low uptake rate among the adult population; only one in seven adults who could benefit from wearing hearing aids utilizes them. Given the status quo of high …

Recreational Music Exposure And Music-Induced Hearing Loss: A Systematic Literature Review, Carolyn Lindenbaum

Dissertations, Theses, and Capstone Projects

Legislation regarding occupational noise exposure is the result of a long period of interest and research; more recently, the effects of recreational noise are receiving increasing attention. Various sources of recreational noise and music exposure have become more widespread among the general public, increasing research in this source of potential risk. The proliferation of personal music players that are easily available and accessible to children and adults has contributed to the spread of leisure music exposure. Leisure music exposure is also common in the attendance of concerts and clubs/discos, and bars/pubs. The present systematic literature review focused exclusively on recreational …

Occlusion Effects In Various Testing Conditions Using Insert Earphones, Amanda M. Desantolo

Dissertations, Theses, and Capstone Projects

The occlusion effect is a well-known phenomenon that can affect audiological testing. Sound energy that would typically escape is trapped when covering the ear(s) and reflected back toward the inner ear. This increases the intensity of the sound, resulting in the “appearance” of a more sensitive threshold. Many aspects of the occlusion effect have been well researched and understood, however there are still aspects that warrant further investigation, such as the degree of occlusion with insert earphones when using partial versus full insertion and whether one or both of the ears are occluded. A within-subject design (n=5) was utilized to …

Typically developing children and children with SLI, ages 8-11 years, participated in a Picture-Word Interference (PWI) task and a Picture-Picture Interference (PPI) task. For both tasks, subjects named a familiar target picture while ignoring an auditory word in the PWI task and an interfering picture in the PPI task. The interfering stimuli were presented …

The Effect Of A Single Bout Of Physical Exertion On Expressive Language And Word Finding In Individuals With Multiple Sclerosis, Marissa A. Barrera

Dissertations, Theses, and Capstone Projects

To date, little research has been conducted on the relationship between fatigue and expressive language among Multiple Sclerosis patients (MS). This study was a response to this knowledge gap. A nonrandom, matched- subject, mixed-factor design model was used with a purposive sample of 17 individuals with MS (five had primary-progressive (PP) MS, and 12 had relapsing-remitting (RR) MS). The research design was subjected to pretesting to ensure validity. Participants were assessed on a range of language tasks after undergoing one bout of cardiovascular exercise (NuStep T5 Recumbent Cross Trainer) and asked to provide a subjective fatigue score. The expressive language …

Executive Control Mechanisms In Bilingualism: Beyond Speed Of Processing, Klara Marton, Mira Goral, Luca Campanelli, Jungmee Yoon, Loraine K. Obler

Publications and Research

The question of interest in this study was whether bilingual individuals show superior executive control compared to monolingual participants. Findings are mixed, with studies showing advantage, disadvantage, or no difference between bilingual and monolingual speakers. In this study, we used different experimental conditions to examine implicit learning, resistance to interference, monitoring, and switching, independently. In addition, we matched our monolingual and bilingual participants on baseline response time. Bilingual participants demonstrated faster implicit learning, greater resistance to interference, more efficient switching compared to monolingual participants. The groups did not differ in monitoring. In conclusion, depending on task complexity and on the …
