Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite

Masters Theses

The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …

Relations Between Oral Pharyngeal Size And Kinematic Measures Of Tongue Related Swallowing Movements, Danielle Monast

Honors Theses

Background: Though the tongue plays a critical role during the oral phase of swallowing, studies have found that the size and shape of tongue movements during swallowing can vary greatly among individuals. One factor that may contribute to this movement variability is oral-pharyngeal cavity geometry. A cavity with a different size and shape may require different movements for efficient swallowing. While there are a number of studies that have attempted to relate the oral-pharyngeal anatomy with features of orofacial movement, these studies focused on speech movements and no studies have directly evaluated the relation between swallowing related tongue movements and …

Effects Of Noise On Cognitive Function During Dual Tasks Across Normally Aging Adults, Jennine Harvey

Theses and Dissertations (ETD)

This study expands upon methods used to investigate cognition and speech perception which have been limited by lack of (a) pre-screening of cognitive function in participants, (b) reporting visual or auditory accuracy and reaction time measures across experimental conditions that examine reaction times, and (c) comprehensive test battery that includes performance across multiple levels of dual task paradigms (DTPs). This study aims to examine group performance on dual tasks (DT) increasing in cognitive (task difficulty) and perceptual load (noise) with age. Participants were divided into two groups based upon age. Group 1 consisted of 14 listeners (Female=11) who were 40-59 …

Aerodynamic And Acoustic Features Of Vocal Effort, Allison Rosenthal

Speech-Language Pathology - Theses

Many voice disorders are associated with an effortful voice; however, there have been very few studies that have examined the physiological changes that contribute to this sense of effort. Determining the factors that contribute to change in vocal effort may help clinicians to effectively target these variables when working with people with voice disorders so that voice improvement is accompanied by decreased vocal effort after treatment. Prior research has shown that alterations in aerodynamic and acoustic variables are often associated with voice disorders involving increased muscular effort, and change in these variables is correlated with abnormal voice qualities. The current …

A Comparison Of Caregiver And Speech-Language Pathologist's Ratings Of Speech Outcome In Oral Cleft Clinic, Emily Swain

Honors Theses

Background: Cleft lip and/or palate is one of the most common congenital anomalies. The goal of treatment of cleft palate is normal speech, but a proportion of children with clefts exhibit speech disorders. Various outcome measures are used, but relatively few have focused on self-assessment or caregiver perception of outcome. The studies that have been done focus on comparing parents' and speech-language pathologists' ratings of speech outcome. These studies can be used to determine the degree to which caregivers are satisfied with speech outcome over time.

Purpose: The purpose of this study was to describe the relationship between speech ratings …

The Measurement Of Auditory Interhemispheric Transfer Time (Ihtt) In Children With Normal Auditory Processing Abilities, Brittany Suzanne Keahey

Doctoral Dissertations

Interhemispheric transfer time (IHTT) is the time it takes for information to be transmitted from one hemisphere to the other. The goal of this study was to determine if differences existed in the IHTT of children 6 to 9 years of age with normal auditory processing abilities by the use of an objective measure (auditory late evoked potentials [ALEPs]), specifically waves P1, N1 and P2. It was hypothesized that there would be no difference in IHTT between the groups due to the age range of participants being tested. The 16 participants were divided into two groups based on age and …

Asymmetrical Speech In Noise Assessment For Children With (Central) Auditory Processing Disorders, Jessica Vaughn

Doctoral Dissertations

The primary purpose of this investigation was to determine if children with (Central) Auditory Processing Disorder have better word recognition abilities for monosyllabic words under monaural speech-in-noise conditions than binaural speech-in-noise conditions. Fifteen participants, five females and ten males, ages 8-10 years, were included in this study. There were 7 children placed in the experimental group with a diagnosis of (C) APD identified from the Louisiana Tech University Speech and Hearing Center. There were 8 typically developing children placed in the control group. Each participant had pure-tone thresholds of 0-20 dB HL for 250-8000 Hz bilaterally. The SCAN-3 for children, …

Effects Of Untrained Earmold Impression Taking On Custom Hearing Protector Device Performance, Kelly R. Pack

Doctoral Dissertations

Today's consumer is increasingly turning to the internet for both healthcare information as well as the purchase of custom hearing protection devices (HPDs). These HPDs are often cast from do-it-yourself home ear impression kits that include a syringe and silicone earmold impression material to be injected into the ear canal. Although not required by law, earmold impressions have typically been taken by medical professionals and other individuals formally trained in the procedures and safety measures of effective earmold impression taking. The main purpose of this study was to determine if do-it-yourself earmold impressions produce HPD's with lower attenuation levels than …

Preschoolers With Speech And Language Impairment: Case Studies From A Teacher-Delivered Phonological Awareness Program, Katherine J. Wickham

Communication Disorders Faculty Publications

Velocardiofacial and DiGeorge syndromes, also known as 22q11.2 deletion syndrome (22q11DS), are congenital-anomaly disorders caused by a de novo hemizygous 22q11.2 deletion mediated by meiotic nonallelic homologous recombination events between low-copy repeats, also known as segmental duplications. Although previous studies exist, each was of small size, and it remains to be determined whether there are parent-of-origin biases for the de novo 22q11.2 deletion. To address this question, we genotyped a total of 389 DNA samples from 22q11DS-affected families. A total of 219 (56%) individuals with 22q11DS had maternal origin and 170 (44%) had paternal origin of the de novo deletion, …

Hearing Loss In The Dental Office: The Effects Of High Speed Dental Drills On Dentists' Hearing, Krisztina Johnson, Jacek Smurzynski, Saravanan Elangovan, Marc Fagelson

ETSU Faculty Works

Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection

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 …

Faculty Publications

The aims of this study were to characterize and quantify time-frequency changes in transient-evoked otoacoustic emissions (TEOAEs) recorded in children diagnosed with retinoblastoma who were receiving carboplatin chemotherapy. A signal processing technique, the wavelet transform (WT), was used to analyze TEOAE waveforms in narrow-band frequency components. Ten children (aged 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were enrolled in the study. TEOAEs were acquired from the children with linear sequences of 70 dB peak equivalent SPL clicks. After WT analysis, TEOAE energy, latency and normalized energy in the narrow-band frequency components were compared before and during carboplatin chemotherapy treatment …
