Physiological And Behavioral Evidence Of Auditory Processing Deficit In Children Suspected Of Auditory Processing Disorder, Sangamanatha Ankmnal Veeranna

Electronic Thesis and Dissertation Repository

A series of studies were carried out to examine the neural and behavioral processing of acoustic stimuli in children with suspected auditory processing disorder (sAPD).

The click-evoked auditory brainstem responses recorded from children with sAPD and adults were analyzed using traditional clinical measures and detailed analysis seeking to explore the separate contributions of axonal conduction and synaptic transmission. Clinical measures revealed significant prolongation of absolute latencies and interwave intervals in children with sAPD compared to adults. Examination of responses delineating axonal vs. synaptic transmission showed frequent delays in synaptic factors and fewer instances of delays related to axonal conduction in …

Perception And Production Of /V/ And /W/ In Hindi Speakers, Vikas Grover

Dissertations, Theses, and Capstone Projects

This dissertation examines the ability of Hindi speakers to identify, discriminate and produce two English phonemes /v/ and /w/ which are difficult for Hindi speakers to distinguish. In Hindi, /v/ and /w/ are used interchangeably. This pattern of use has transferred to Indian English, resulting in English /v/ and /w/ words showing variable pronunciations (e.g., “whale” or “vale” for the word “whale”). Hindi speakers were asked to identify, discriminate and produce tokens of /v/ and /w/. This study also examined whether experience with American English, related to the length of residence (LOR) in the US affects Hindi listeners’ perception and …

Language-Mixing In Discourse In Bilingual Individuals With Non-Fluent Aphasia, Avanthi Paplikar

Dissertations, Theses, and Capstone Projects

Language-mixing (LM) as defined by Chengappa (2009, p. 417) is an “intra-sentential phenomenon referred to as the mixing of various linguistic units (morphemes, words, modifiers, phrases, etc.), primarily from two participating grammatical systems”. LM is influenced by grammatical, environmental, and social constraints (e.g., Milroy & Wei, 1995; Bhat & Chengappa, 2005). Researchers have suggested that LM in patients with aphasia is a communicative strategy used to achieve successful exchanges between speakers; the effectiveness of this mixing, however, had yet to be demonstrated quantitatively.

In the current study we investigated whether LM is present in bilingual speakers with aphasia, and if …

Reflection: Effect Of Age On Auditory Brainstem Responses In Mice With Epha4 Mutations, Erica L. Hoogerland

Senior Honors Projects, 2010-2019

Presbycusis, or age-related hearing loss is a condition that affects approximately 40% of the population over 65 years of age (Gates & Mills, 2005). Studying the effects of EphA4 mutations (wild type, heterozygous, and homozygous) mice is fundamental in understanding the relationship between onset of age-related hearing loss, in both the mammalian population and the human population. In order to further understanding of age-related hearing loss, the researchers evaluated thirty-six mice in a preliminary study from two months to nine months of age. Following data analysis, the researchers confirmed the results by continuing a second round of testing. The hearing …

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 …

Release From Masking: Behavioral And Physiological Masking Level Differences, Sarah L. Hodgson

Dissertations, 2014-2019

Binaural hearing offers several advantages over monaural hearing and is believed to be one factor that is involved in the ability to understand speech in background noise. Binaural hearing involves analysis of interaural timing and intensity differences in signals arriving at the two ears which provides listeners with sound localization cues as well as signal in noise detection. When sounds arrive at each ear at slightly different times, there may be a release from the effects of background noise, allowing listeners to detect softer sounds in noise. Masking Level Differences (MLDs) have been widely used to evaluate behavioral binaural processing. …

Variability In Clinically Measured Wideband Acoustic Immittance Over Time In Young And Old Adults, Allison G. Mcgrath

Dissertations, 2014-2019

Wideband acoustic immittance (WAI) measures of the middle ear have the potential to increase our ability to detect changes in the middle ear transfer function not seen using traditional tympanometry. In order to use this new tool diagnostically we must first understand its normal clinical variability. The present study aimed to investigate the variability that occurs when wideband acoustic immittance (WAI) is measured clinically within subjects as a function of subject age, as a function of time, and as a function of pressure. A total of thirty-six ears from eighteen subjects were studied (n=18 young adults ears, n=18 older adult …

The Effect Music Has In Speech Therapy, Emily K. Nester

Honors Theses

The purpose of this exploratory study was to determine the use of music in speech therapy. A survey was sent via email to Mississippi Speech-Language-Hearing Association (MSHA) certified speech-language pathologists to acquire knowledge on the use of music in their therapy sessions. The author used the source, SurveyMonkey, to collect and analyze the data. The data was used to determine the prevalence of music in speech therapy. In addition, when music was used, the data portrayed how music was incorporated into therapy and the particular gender, genre, and/or disorder preferred.

Verification And Quantification Of Surface Electromyographic (Emg) Activity Of The Masseter Muscle, Kelsey Bowles

Honors Theses

Purpose: The goal of the present study is to develop and evaluate an automated technique for measuring biting and chewing related surface electromyographic (EMG) activity of the masseter muscle.

Methods: Data from 28 neurologically healthy participants between the ages of 18-40 were selected for this study. The procedure for collecting the bite/chew data consisted of the participant biting down and chewing three small breath mints while an EMG sensor recorded the masseter muscle activity. A five-step Matlab-based algorithm was created to accurately identify onsets and offsets of each bite and chew event.

Results: Compared to manual measurements using standard …

Acoustic Correlates Of Speech Naturalness In Post-Treatment Adults Who Stutter: Role Of Speaking Rate, Caylee Jessen

Honors Theses

Purpose: While many stuttering therapy programs can result in a decrease in stuttering behaviors among participants, some clients leave therapy with speech sounding unnatural due in part to the therapy techniques themselves. The aim of the current study is to examine associations between selected acoustic measures of speaking rate and listener ratings of speech naturalness in a group of adults who stutter following participation in an intensive fluency shaping treatment program.

Methods: Twenty-nine adults who stutter, drawn from an existing database of speech samples, served as participants. All participants had recently completed a four-week group-based intensive fluency shaping treatment program. …

Memory Support For Adults With Alzheimer’S Disease: Applications For Speech-Language Pathologists, Laura Dober

Honors Theses

Alzheimer’s disease (AD) is the most common form of dementia and is known to cause progressive and severely debilitating impairments in cognition, especially in memory. Deficits in memory and cognition are clearly reflected in the communication of people diagnosed with this progressive, degenerative, incurable disease, placing speech-language pathologists as important members of a care team for adults with AD. Speech-language pathologists provide treatment to support memory, and therefore communication, in people with AD through direct and indirect methods. Some examples of memory supportive strategies include spaced-retrieval learning, the use of external memory aids and assistive technology, Montessori methods, and manipulations …

Collaboration Occurring Between Professionals In Today's Schools, Kara Lynn Doglio

The current utilization of collaboration as a viable service delivery option is unknown. The purpose of this study was to identify whether collaboration was occurring and with whom it was occurring. This study also sought to identify similarities and differences across four participant groups regarding perceived beliefs and reported practices in professional collaboration. While administrators took a separate survey than educators (general and special …

The Effect Of A Fluent Signing Narrator On Quality Of Maternal Behavior During E-Book Shared Reading Interactions With Their Children With Hearing Loss, Mar Alejandra Bonilla Yáñez

Open Access Theses & Dissertations

Purpose: The average high school student with hearing loss graduates reading at a 4th grade level. A factor that may contribute to the literacy development in children with typical hearing is language modeling and support surrounding shared book reading. The shared book reading experiences of children with hearing loss (CHL) and their parents may be different in quantity and quality from their peers with typical hearing. There is evidence reporting parental frustration and feeling of incompetence when reading to their CHL due to a sensory mismatch between the childâ??s and the parentâ??s mode of communication and skills. This study investigated …

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 …

The Effects Of Bilingualism On Auditory Selective Attention In Normal-Hearing Adults, Francisco Fernandez

Open Access Theses & Dissertations

Bilingual speakers have been shown to be more adept than monolingual speakers at actively blocking useless information in the visual modalities. This advantage should be observed in both the visual and the auditory modalities using tasks of inhibitory control. However, very little is known regarding how bilingualism influences inhibitory control in the perception of auditory information. By using an auditory test of inhibition, such as the utilization of a Dichotic Listening task, bilinguals are expected to display an increased measure of cognitive ability.

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 …

Does Knowledge Of Concussion Symptoms Influence An Athlete's Self-Report Of A History Of Concussion Across Gender And Age?, Kara Ashlan Greco

Open Access Theses & Dissertations

Background: The incidence of sport-related concussion is debatable. While the Centers for Disease Control and Prevention report an extrapolated incidence of 1.6 to 3.2 million recreational/sports-related traumatic brain injuries a year, the suspicion is that the incidence is much higher (CDC, 2014). An important consideration in determining the incidence involves whether an athleteâ??s knowledge of what a concussion is influences their self-report of prior concussions.

Purpose: The purpose of this study is to replicate and extend Pfirman (2015) in determining whether providing information about concussion will increase the self-report of a history of concussion. Furthermore, this study investigates whether there …

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, …

The Use Of Gesture In Self-Initiated Self-Repair Sequences By Persons With Non-Fluent Aphasia, Eleanor M. Feltner

Theses and Dissertations--Linguistics

This study examines the relationship between types of gestures and instances of self-initiated self-repair (SISR) used by persons with non-fluent aphasia (NFA), which is a type of aphasia characterized by stilted speech or signing (Papathanasiou et al., 2013), in interactions with clinicians. Conversation repairs in this study are assessed using the framework of Conversation Analysis (CA), which is an approach for describing, analyzing, and understanding social interaction (Sidnell, 2010). Previous linguistic studies have demonstrated a distinct preference for the use of gesture during a repair by persons with aphasia (Goodwin, 1995; Klippi, 2015; Wilkinson, 2013). This study draws more conclusive …

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 …

An Investigation Of Motor Speech And Motor Limb Movements Following A Sport-Related Concussion-An Extension Study, Linda Phan

Open Access Theses & Dissertations

Background: Minimal research is available regarding the effects on motor speech and motor limb movements following a sport-related concussion (SRC). A sensitive measure is necessary to detect subtle deficits in motor speech, as it may provide diagnostic insight involving return-to- play decisions.

Purpose: This research aimed at replicating and extending a previous research study, Hewitt (2015), conducted at the University of Texas at El Paso. The Hewitt (2015) study examined motor speech tasks and motor limb tasks which included the following: oral diadochokinetics (DDK): sequential motion rate (SMR)(i.e. /puh-tuh-kuh/) and alternating motion rate (AMR) (i.e. /puhpuhpuh/, /tuhtuhtuh/, /kuhkuhkuh/); speech rate …
