Dialect Variation Assessment In Speech-Language Pathology, Maliah Wilkinson

Honors Theses

During speech and language assessment, speech language pathologists often utilize tools from sociolinguistics to differentiate between accent and dialect variation from actual speech or language impairments. Perceptual dialectology, is one of these tools. This method of research seeks to investigate the linguistic perspectives of various populations in specific situations (Montgomery, 2012, p. 638). To investigate the perspectives of college students, linguists, and speech-language pathologists surveys analyzed they perceptions of dialects in various settings and their backgrounds. Results from the surveys indicate linguists who participated have educational experience with dialects but not dialect assessments. While speech-language pathologists, have certification that insists …

The Auditory Radiation In Traumatic Brain Damage: Diffusion Tensor Imaging Study, Jane Walsh

Honors Theses

Hearing loss is a known symptom among people who suffer from traumatic brain injuries. Studies have shown that sensorineural hearing loss is the most common type of hearing loss resulting from traumatic brain injury. However, it is not well understood whether the auditory pathway is affected by traumatic brain injury. In this study, we examined the auditory radiation, using diffusion tensor imaging data and probabilistic tractography. Fifty-three veterans with traumatic brain injury and forty-four veterans without traumatic brain injury are compared. There was no significant difference in fractional anisotropy of the auditory radiation between those with and without traumatic brain …

Induction Of Nocebo Effects By Verbal Suggestions During The Caloric Test, Abbey Weist

Dissertations, 2020-current

The caloric test is the most frequently performed vestibular diagnostic test and is considered the “gold-standard” for the assessment of the peripheral vestibular system. Using a warm or cool stimulus, the caloric test alters the temperature gradient in the vestibular system resulting in nausea and dizziness. The nocebo effect is a phenomenon that can occur when negative expectations result in negative effects. No study has examined whether expectations of nausea and dizziness during the caloric test enhance the experience of unwanted symptoms. The purpose of this investigation was to determine whether a nocebo response can be elicited during the caloric …

Music And Speech Perception In Pre-Lingually Deafened Young Listeners With Cochlear Implants: A Preliminary Study Using Sung Speech, Harley J. Wheeler

Dissertations, 2020-current

Timbre and pitch cues, though definitionally and physically distinct characteristics of sound, are attributes of all sound signals. A body of literature has shown that alteration of one characteristic can influence the perception of the other; e.g., speech spoken with an atypical contour of pitch can influence a listener's accuracy in identifying the words spoken; conversely, whether a melodic contour is presented via a MIDI piano representation or as sung speech can influence the accuracy of identification of the pitches' contour. Trends for these interactions have been documented for normal hearing children and adults, as well as postlingually deafened adult …

Vestibular Evoked Myogenic Potentials And Postural Control In Adults With Age-Related Hearing Loss, Steven Michael Doettl

Theses and Dissertations (ETD)

It is well-documented that auditory thresholds decrease with age, which can be referred to as Age-related hearing loss (ARHL). ARHL is one of the most common conditions affecting older adults and is associated with several conditions including decreased postural stability and falls. Age-related changes to auditory function have been attributed to, through histopathological study, specific degradation of the sensory, supporting, and afferent structures of the cochlea. Vestibular function, as measured through vestibular evoked myogenic potentials (VEMPs) also show decreases with age. VEMPs are a measurement of evoked potentials generated by auditory stimulation of the utricle and saccule measured through a …

An Investigation Of Pictography And Verbal Rehearsal On College Students’ Recall Of Expository Texts, Joshua Woodruff

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: This study investigated the effects of pictography with and without verbal rehearsal on informational recall of two types of expository texts. This study is part of a research program to further develop a treatment for younger students with language impairment called Sketch-and-Speak.

Procedure: 66 undergraduate students between the ages of 18 and 40 were tested on recall of concrete versus abstract expository texts in a randomized group experiment across three conditions: pictography with and without verbal rehearsal versus re-reading. Participants were trained on the assigned testing condition and then proceeded to the experimental procedure. In the experimental procedure, …

Respiratory Differences In Spontaneous And Scripted Speech Among Bilingual Adults, Anna Irene Sagan

Honors Program Theses

This investigation explored respiratory differences between a speaker’s first language (L1) and second language (L2) during spontaneous and scripted speech in six adult bilingual speakers (two native bilingual speakers and four non-native bilingual speakers). Respiratory kinematic data using Respitrace respiratory inductance plethysmography and acoustic recordings were collected during five tasks: tidal breathing at rest, scripted speech in L1, spontaneous speech in L1, scripted speech in L2, and spontaneous speech in L2. Results indicated a significant interaction effect between proficiency and syllables produced during spontaneous speech, but no other significant differences were found among inspiratory/expiratory duration, task, proficiency or language. The …

Social Conformity And The Line Judgement Task For Adolescents With Asd, Jamie Mcclendon

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The primary intent of this study is to add to the growing research regarding social functioning and theory of mind (ToM) of young adults with autism spectrum disorder (ASD). This study takes into account the Solomon Asch line judgement tasks effect on peer pressure and social conformity. Previous research has shown that there is a discrepancy in the conformity exhibited by typically developing individuals (TD) and ASD individuals. This study seeks to address the degree to which ASD individuals are affected by social influence and how likely they will be to conform. Conformity rates will be compared to that of …

School-Based Speech-Language Pathologist's Perceptions Of Sensory Food Aversions In Children, Ellen Monroe

Electronic Theses and Dissertations

Sensory Food Aversions occur frequently in children who are likely to appear on Speech-Language Pathologist’s (SLP’s) caseloads. The lack of research regarding intervention for Sensory Food Aversions in schools and the assertion of a gap in school-based services for children with feeding disorders was a significant indicator for the need of the study. A quantitative, descriptive, exploratory research design was selected using a self-developed questionnaire in order to exploreschool-based SLP’s perceptions of their knowledge and skills related to Sensory Food Aversions, as well as determine resources available for working with this population. Findings from the study suggest a need for …

Perceptions Of Guilt Of Individuals With A Visible Communication Disorder Versus An Invisible Communication Disorder, Zoe Hochberg

Honors Scholar Theses

This study explored how communication disorders may impact listeners’ perception of guilt. More specifically, it looked at how visible communication disorders (e.g., stuttering) and invisible communication disorders (e.g., high functioning autism) are judged by the general public. 51 adults (18-71 years) participated in the study which asked them to view video recordings of narrative samples produced by an individual who stuttered (PWS), an individual with high-functioning autism (PHFA), and an individual with no communication disorder (PNCD). Participants were not informed of the individuals’ communication abilities (PWS, PHFA, or PNCD), but were told that one of the individuals had committed a …

Hearing Loss: Investigating The Comfort, Confidence, Knowledge, And Preparedness Of Kentucky School-Based Speech-Language Pathologists., Amanda Matsumoto

Development Of The Caregiver-Child Auditory Skills Tracking (Cast) Scale: A Pilot Study On Caregiver Implementation Via International Telepractice, Elizabeth Ocampo-Roman

Graduate Theses and Dissertations

Parent engagement is a key component during early language development for all children, but particularly for a child with hearing loss. Through the application of technology-based models of service delivery such as telehealth, researchers have found an increase in parent-child engagement during auditory-verbal therapy (AVT) sessions due to the physical absence of the provider and parents becoming the primary language facilitators. However, current measures of parent-child interactions do not have a coding system to monitor facilitation of auditory skills. This present study will discuss the development of the Caregiver-Child Auditory Skills Tracking (CAST) Scale to track progress of caregiver implementation …

Advanced Phenotyping Of Otosclerosis In An Ontario Population And Two Large Newfoundland Families, Matthew B. Lucas

Electronic Thesis and Dissertation Repository

Otosclerosis is a relatively common hearing loss disorder characterized by abnormal bone growth in the otic capsule leading to stapes fixation. In approximately half of cases, otosclerosis is inherited as an autosomal dominant trait. Typically, gene discovery efforts rely on surgical confirmation, audiometry and occasionally acoustic reflexes to identify affected cases of otosclerosis within families, requiring that the otosclerosis was at an advanced stage to be detected. This makes it difficult to identify individuals with early otosclerosis. The use of advanced phenotyping to identify cases of otosclerosis was tested in an Ontario otosclerotic population as well as in two large …

Vocal Health Of Choral Singers From Kenya And The United States: Dysphonia And Vocal Fatigue In Relation To Musical Genres, Morgan Jolley Burburan

USF Tampa Graduate Theses and Dissertations

The purpose of this mixed-methods study was to investigate the vocal health of choral singers from Kenya and the United States and to determine whether genre (classical choral, traditional Kenya, and Contemporary Commercial Music [CCM]) had any impact on healthy vocal production, particularly as it related to vocal fatigue. Participants were adult singers (N = 94) in two semi-professional choirs, the Nairobi Chamber Chorus (NCC) from Kenya (n = 25) and the Festival Singers of Florida (FSOF) from the United States (n = 69). Singers’ perceived overall vocal health was measured using multiparametric clinical self-reporting instruments and acoustical assessment. Singers’ …

Self-Disclosure Of Stuttering To Various Social Referent Groups And Its Relationships With Psychological Distress, Katrina Rourke

Honors Theses

Purpose: Research has shown that there are benefits associated with verbal disclosure of stuttering. However, most of the existing literature on stuttering disclosure has focused on how it affects listener perceptions of people who stutter, and little is known about speaker-focused outcomes of verbal stuttering disclosure. The purpose of the current study was to investigate who people who stutter verbally disclose to (e.g. friends, co-workers, neighbors) and if relationships between extent of disclosure and distress vary depending on the confidant’s social referent group. The seven social referent groups of focus were family, friends, romantic partners, people in the workplace, healthcare …

Acoustic Changes During Passage Reading In Speakers With Parkinson's Disease, Kimberly C. Grubbs

LSU Master's Theses

Purpose: The purpose of this study was to evaluate speech changes in Parkinson’s disease (PD) while reading a passage, using both local (i.e., segment level) and global (i.e., utterance level) acoustic measures.

Methods: 20 speakers participated in the study (10 PD, 10 neurologically healthy controls). The speakers were asked to read The Caterpillar passage in a conversational mode. A total of five acoustic measures were included (local: vowel duration, Euclidean distance between corner vowels and schwa; global: articulation rate, F0/intensity range). These acoustic measures were compared between two sentences located in the two positions within the paragraph, initial and final. …

The Relationship Between Working Memory, Procedural Learning, And Declarative Memory In Children With Specific Language Impairment, Allison Grace Herring

LSU Master's Theses

Background: Children with specific language impairment (SLI) have recently been suggested to have subclinical deficits in executive function skills. The current study seeks to better understand these deficits by exploring the role of nonverbal working memory in word learning and statistical learning in this population. Method: Participants included typically developing children along with children with SLI ranging from ages 8-12 years old. Word learning was assessed using a fast-mapping task, statistical learning was measured using a word-segmentation task, and nonverbal working memory was measured using an N-back task. Results: A significant difference was found between children’s segmentation accuracy scores. …

This thesis will explore the Cerebral Dominance theory of stuttering and its applicability to neuroimaging and bilingualism. Furthermore, this thesis will determine the presence and extent of the impact of bilingualism on people who stutter. The cultural, gender, language and neurological influences on stuttering for those who are bilingual will also be examined. Through this analysis, the positive and negative impact of …

Brain Activation For Cochlear Implant Users: A Pilot Fnirs Study, Makayla Gill, Ceceli Bonitto, Bailey Heaton, Yingying Wang

UCARE Research Products

Cochlear implants (CIs) have become a widespread device for individuals with severe-to-profound sensorineural hearing loss (SNHL) to regain hearing ability and improve quality of life. However, the brain needs to adapt to this bionic device and relearn the function of hearing, especially for speech sounds. Because the auditory inputs through a CI are not the same as those heard by individuals with typical hearing, aural rehabilitation takes time. The goal of this study is to examine neural bases of speech perception in adult CI users using functional near-infrared spectroscopy (fNIRS). Two adults with bilateral SNHL and CI(s) were fitted with …

Acoustic Characteristics Of Word-Final American English Liquids Produced By L2 Adult Speakers, Judith A. Espinal

LSU Master's Theses

In this study, the acoustic differences between native English speakers’ (L1) and native-Korean speakers’ (L2) production of American English liquids /ɹ/, /l/ and /ɹl/ were examined among 14 Korean speakers and 13 English speakers. Temporal measures included (1) relative timing of maximum constriction and (2) duration of vocalic nuclei. Spectral measures included (1) Euclidean distance between /ɹ/ and /l/ and (2) frequency difference between F2 and F3. The results indicated a significant interaction between speaker group and phonetic stimuli. That is, L2 speakers produced a similar degree of constriction across semivowels, whereas L1 speakers produced varying degrees of F2-F3 constrictions …
