Nature Of The Verbal Fluency Task In Concussed Athletes, Paulina Mejia

Open Access Theses & Dissertations

Background: Verbal fluency is a common test used to assess naming in individuals with brain injury. Troyer (1997) reported that naming components such as phonemic clusters and categorical switching might be more sensitive to the presence of brain injury than a reduction in the total number of words that is commonly used as a measure. Phonemic task refers to the F-A-S naming task while the semantic task refers to the animal naming task because of the frequent production of the phonemic cluster on the F-A-S and semantic clusters on the animal naming task (Troyer, 1997).

Purpose: The purpose of this …

The Effect Of A Fluent Signing Narrator On Children's Behavior During Technology-Enhanced Shared Reading With Children With Hearing Loss And Their Parents, Gabriela Itzel Rodriguez

Open Access Theses & Dissertations

Shared reading plays an essential role in the language and literacy development of children who are at risk of future problems in those areas. Children with hearing loss (CHL) are a group who usually experience limited and poor quality activities that foster literacy development such as shared reading (SR). Researchers examining high quality interactions have rated child behaviors, primarily attention and initiation, during shared reading and play based activities finding positive correlations between these behaviors and the overall development in typically developing children as well as in children with other impairments such as Autism Spectrum Disorder and Down syndrome (Kim …

The Spanish-English Bilingual: A Cross-Classfication Comparison Of Maze Use In Children, Jessica Valles

Open Access Theses & Dissertations

With the continual increase of bilingual individuals in the United States, there is a critical need for research that can appropriately identify unique characteristics of language production for these individuals. In particular, maze use, or errors in production have been identified as a characteristic of language that typically occurs more in bilinguals' speech production than in monolingual productions. Research comparing bilingual maze use in individuals who are typically developing with bilingual maze use individuals who are language impaired is limited. To compare these bilingual children with language impairment with to their typically developing peers, children were paired by age, grade, …

Understanding The Stigma Of Hearing Loss And How If Affects The Patient And Treatment Process, Carolyn M. Zaitzew

Williams Honors College, Honors Research Projects

This project is a literature review on the topic of hearing loss related stigma and the effects it has on persons with hearing loss. There has not been very much research conducted on this topic, which limited the paper’s content. Through researching and analyzing previous studies, it was found that a stigma related to hearing loss still exists today and has multiple effects on persons with hearing loss. The stigma can put negative stress on patients with hearing loss, both psychologically and socially, and may even cause them to not seek or accept treatment when needed. Younger adults are more …

Under-Reactive But Easily Distracted: An Fmri Investigation Of Attentional Capture In Autism Spectrum Disorder, Brandon Keehn, Aarti K N Nair, Alan J. Lincoln, Jeanne Townsend, Ralph Axel Müller

Department of Speech, Language, and Hearing Sciences Faculty Publications

For individuals with autism spectrum disorder (ASD), salient behaviorally-relevant information often fails to capture attention, while subtle behaviorally-irrelevant details commonly induce a state of distraction. The present study used functional magnetic resonance imaging (fMRI) to investigate the neurocognitive networks underlying attentional capture in sixteen high-functioning children and adolescents with ASD and twenty-one typically developing (TD) individuals. Participants completed a rapid serial visual presentation paradigm designed to investigate activation of attentional networks to behaviorally-relevant targets and contingent attention capture by task-irrelevant distractors. In individuals with ASD, target stimuli failed to trigger bottom-up activation of the ventral attentional network and the cerebellum. …

Dysphagia Management And Research In An Acute-Care Military Treatment Facility: The Role Of Applied Informatics, Nancy Pearl Solomon, Angela M. Dietsch, Katie E. Dietrich-Burns, Edda L. Styrmisdottir, Christopher S. Armao

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: This report describes the development and preliminary analysis of a database for traumatically injured military service members with dysphagia.

Methods: A multidimensional database was developed to capture clinical variables related to swallowing. Data were derived from clinical records and instrumental swallow studies, and ranged from demographics, injury characteristics, swallowing biomechanics, medications, and standardized tools (e.g.. Glasgow Coma Scale, Penetration-Aspiration Scale). Bayesian Belief Network modeling was used to analyze the data at intermediate points, guide data collection, and predict outcomes. Predictive models were validated with independent data via receiver operating characteristic curves.

Results: The first iteration of …

Differential Effects Of Cdh23753a On Auditory And Vestibular Functional Aging In C57bl/6j Mice, Bruce E. Mock, Sarath Vijayakumar, Jessica Pierce, Timothy A. Jones, Sherri M. Jones

Department of Special Education and Communication Disorders: Faculty Publications

The C57BL/6J (B6) mouse strain carries a cadherin 23 mutation (Cdh23^753A, also known as Ahl), which affects inner ear structures and results in age-related hearing loss. The B6.CAST strain harbors the wild type Cdh23 gene, and hence, the influence of Ahl is absent. The purpose of the present study was to characterize the effect of age and gender on gravity receptor function in B6 and B6.CAST strains and to compare functional aging between auditory and vestibular modalities. Auditory sensitivity declined at significantly faster rates than gravity receptor sensitivity for both strains. Indeed, vestibular functional aging was …

Infant-Driven Feeding Vs. Scheduled Feeding: The Effect On Hospital Length Of Stay, Lori L. Messer

Walden Dissertations and Doctoral Studies

Developmental delays related to feeding dysfunction in premature infants can lead to lengthy hospitalizations and increased healthcare costs initially and throughout the first year of the child's life. The purpose of this project was to use readiness-to-feed assessments to evaluate the impact of an infant-driven feeding protocol on length of stay. The project compared the length of stay of 2 groups of infants: a demand fed according to a readiness-to-feed protocol (protocol group, n = 14) and a traditionally fed according to scheduled, volume-driven feedings (traditional group, n = 15). The logic model served as the change management framework and …

Fundamental Frequency Characteristics Of Modal And Vocal Fry Registers, Heidi Brubaker, Jason Albertson Whitfield Ph.D., Jane Schoonmaker Rodgers D.M.A.

Honors Projects

This study examined the distribution of fundamental frequencies in the connected speech of 14 healthy young adults. Acoustic analysis of fundamental frequency was performed on previously collected speech samples of a phonetically balanced reading passage. For the first three sentences of the reading passage, fundamental frequency contours were extracted using PRAAT, a speech analysis software package. The accuracy of these contours were visually verified and manually corrected when needed. The distribution of the fundamental frequency histories for each sample were then analyzed using Gaussian Mixture Model analyses in MATLAB. For most speakers, four statistical modes were identified in the data …
