Effects Of Delayed Auditory Feedback On The Bereitschaftspotential, Jennifer L. Johnson

Theses and Dissertations

This study examined the brain electrical activity of normal speakers in a non-delayed auditory feedback (DAF) condition and when experiencing DAF to determine the effect DAF would have on the Bereitschaftspotential (BP). The BP reflects the preparatory state of a person prior to motor execution of an act and can be observed 1500 to 500 ms prior to voluntary movement. The participants in the study included 10 adults with normal speech. Each read a series of 30 sentences, both without DAF and with DAF, while the BP was measured. Results indicate that the BP is present across the scalp in …

Split-Half Reliability Of Mlu And Mlu2 In Two Methods Of Utterance Segmentation, Alyse Diana Kemeny

Theses and Dissertations

Concerns regarding Mean Length of Utterance (MLU) has led to adaptations of this method of analysis. A recent study by Johnston (2001) introduced an alternative to MLU called MLU2. The current study investigates the split-half reliability of MLU and MLU2 as well as another alternative, Median Length of Utterance (Med-LU). Split-half reliability was found for these methods when segmented into Phonological and Communication Units. Split-half reliability of MLU2 was generally higher than that of MLU, and both were higher than Med-LU. The study suggests that MLU2 may also be a valuable tool for clinicians in analyzing child language.

Psychometrically Equivalent Cantonese Bisyllabic Word Recognition Materials Spoken By Male And Female Talkers, Brooke Kristin Conklin

Theses and Dissertations

The purpose of this study was to create psychometrically equivalent word lists in the language of Cantonese for word recognition testing. Frequently used bisyllabic Cantonese words were recorded by a native female and male talker. The word lists were evaluated by administering the word recognition lists to 20 native speakers of Cantonese with normal hearing. Each list was presented at 10 different intensity levels ranging from -5 to 40 dB HL in 5 dB increments. Logistic regression was used to determine the words with the steepest logistic regression slopes. The 200 words with the steepest slopes were then formulated into …

Inter- And Intra-Subject Variability: A Palatometric Study, Marybeth Corey Sanders

Theses and Dissertations

Electropalatometry (EPM) has proven to be a useful clinical and research tool for measuring tongue-to-palate contact. The goal of this study was to determine whether the development of a database of standardized palatometric articulation files is feasible by examining the variability which exists within and between speakers. Twenty standard American English dialect speakers were fitted with palatometer pseudopalates. Test stimuli were VCV nonsense words using a schwa in the initial position, the 15 palatal consonants, and three corner vowels, /a/, /i/, /u/. From these palatometric recordings a variability index was created to examine intra- and interspeaker variability. Different aspects of …

The Relationship Between Pragmatic Language And Behavior Subtypes In Typically Developing Children, Lisa Jeppson Christensen

Theses and Dissertations

This study examines the relationship between syntactic and pragmatic language and reticence, solitary-active passive withdrawal, solitary-passive withdrawal, prosocial skills, and likeability. The Children's Communication Checklist (CCC-2), a language checklist, and Teacher Behavior Rating Scale (TBRS), a behavior checklist, were completed by three 2nd-grade teachers and three 4th-grade teachers about each of their students. Factor analysis was used to determine two composite language measures from the CCC-2 scales. The results of two hierarchal regression analyses indicated that social behaviors were significant predictors of pragmatic language, but not structural language. In particular, solitary-passive withdrawal and reticence were significant predictors of pragmatic language …

Social Outcomes Of Students With Language Impairment: An Eight-Year Follow-Up Study, Meghan A. Baldridge

Theses and Dissertations

This study re-examined the language and social skills of four females with language impairment who were initially studied eight years ago (Brinton, Fujiki, Montague, & Hanton, 2000; Fujiki, Brinton, Isaacson, & Summers, 2001). Language measures included the Clinical Evaluation of Language Fundamentals-Fourth Edition (Semel, Wiig, & Secord, 2003) and a thirty minute language sample. Social measures included the UCLA Loneliness Scale-Version 3 (Russell, 1996), parent, teacher and student forms of the Social Skills Rating System (Gresham & Elliott, 1990), and an interview with each participant's teacher or speech-language pathologist. Results of the current assessment were compared to results from the …

Phlebitis Rates In Trauma Patients: Peripheral Intravenous Catheters Started In Or Outside The Emergency Department, Ligia J. Zarate

Theses and Dissertations

Ligia J. Zarate College of Nursing Master of Science Peripheral catheter-related phlebitis is the inflammation of a superficial vein that can lead to infection or thrombus formation if untreated. About 150 million peripheral intravenous catheters (PIVC) are inserted in the United States each year with phlebitis rates reported between 5% and 70%. Many PIVCs are started on trauma patients, but the rate of phlebitis in trauma patients whether the PIVC is started outside the emergency department (ED) or inside the ED is unknown. Therefore, the purpose of this pilot study was to determine phlebitis rates in trauma patients when PIVC's …

Vocal Efficiency In Trained Singers Vs. Non-Singers, Kristi Sue Fulton

Theses and Dissertations

Vocal efficiency is a measure of the efficiency of the energy conversion process from aerodynamic power to acoustic power. Few studies have been conducted to measure vocal efficiency in trained singers to determine whether "vocal athletes" are more efficient than non-singers. Data were collected from 20 trained singers (10 male and 10 female) and 20 non-singers (10 male and 10 female) to determine if there were any significant differences between the two groups. During the recording, each participant produced a series of syllables at combinations of three different levels of pitch and loudness. The acoustic and aerodynamic data were analyzed …

The Impact Of Vocal Function Exercises On Normal Voice Production, Karen Hart Thomas

Theses and Dissertations

This study attempted to replicate and expand previously published research in order to increase our understanding of how Vocal Function Exercises (VFE) might improve vocal function in normal voices. Measures were made to reflect potential post-treatment changes in acoustic and aerodynamic variables, including a measure of vocal efficiency. The participants of the study included 35 adults with normal voices. Each completed a series of speech tasks (sustained vowels, maximum phonation time, reading of a standardized passage, and repetition of syllable strings) before and after a four-week treatment period. Testing of pre- and post-treatment data revealed no clear improvement in acoustic …

Narrative Skills In Children With Spina Bifida And Hydrocephalus, Melissa Ann Halliday

Theses and Dissertations

This study examined how 22 children with spina bifida and hydrocephalus (SBH) and 22 matched control children with the same vocabulary age (VA) performed on story retelling and story generation tasks. The children were asked to retell two stories of different lengths (Stein and Glenn's Melvin, the Skinny Mouse and The Tiger's Whisker) and generate two stories from different stimuli (wordless picture book and verbal story starter). Analyses were conducted in terms of global narrative organization (story structure), local connection of ideas (cohesion), and productivity (number of words and utterances). Two-way ANOVAs were conducted to analyze how the stories and …

Patterns Of Anticipatory Coarticulation In Adults And Typically Developing Children, Kurtt R. Boucher

Theses and Dissertations

Coarticulation is the kinematic and spectral overlap between adjacent sounds during speech production. Coarticulation patterns in typical adults have been well established; however, the manner in which coarticulation is developed in children is still unclear. Research has provided conflicting views, showing that children exhibit more, less, or an equal degree of coarticulation when compared to adult speakers. Considering the divergent findings present in the literature regarding coarticulation in children, the purpose of the present study is to further investigate anticipatory coarticulation in typically developing young children between the ages of three and six years. This study focuses on the acoustic …

Values In Family Therapy Practice And Research: An Invitation For Reflection, Stephen T. Fife, Jason B. Whiting Phd

Faculty Publications

Values have been shown to be a pervasive part of both marriage and family therapy (MFT) clinical practice and research. Yet, many therapists and researchers remain unclear about how values affect their work. This article examines the influence of Western philosophical assumptions and therapy traditions in light of current understandings of values in therapy. The influence of values in MFT research processes is similarly examined. Implications for how family therapy professionals can be more reflective and sophisticated in their understanding of values in clinical practice and scientific inquiry are discussed. Suggestions for addressing values in MFT training also are given.

Psychometrically Equivalent Trisyllabic Words For Speech Reception Threshold Testing In Cantonese, Misty Noelani Kim

Theses and Dissertations

The purpose of this study was to develop, digitally record, evaluate, and equate Cantonese trisyllabic words which could then be used in the measurement of the speech reception threshold. A selection of 90 frequently utilized trisyllabic words were selected and then digitally recorded by male and female talkers of Standard Cantonese and presented to 20 subjects with normal hearing beginning at 6 dB below their pure-tone average (PTA) and ascending in 2 dB increments until one of the following criteria had been met: (a) the participant responded correctly to 100% of the test items, or (b) the presentation level reached …

Neurophysiologic And Behavioral Measures Of Phonetic Perception In Adult Second Language Speakers Of Spanish, Jaden D. Hellewell

Theses and Dissertations

Infants 6-8 months old are able to identify nearly every speech sound contrast on which they have been tested, regardless of whether that contrast represents an across-category (two different phonemes) phonetic change in their native language or not. A child's ability to identify non-native consonant contrasts greatly diminishes by 11-12 months of age. The present study examined speech sound discrimination in three groups of listeners. Adult second language (L2) listeners of Spanish were compared with native English listeners with no knowledge of Spanish and native Mexican listeners to determine if they would show the ability to discriminate phonetic distinctions that …

Foster Parent Pre-Service Training Programs: A Content Analysis Of Four Common Curricula, Jason B. Whiting Phd, Paul Huber, Alice Koech

Faculty Publications

This study compares four curricula commonly used in the pre-service training of US foster parents. Stufflebeam's (1983) CIPP model for program evaluation was used to guide a content analysis of each curriculum, with specific attention to the content and training methodology used. The content was examined to determine if it covered topics identified as germane to the task of fostering children. The instructional methodology of each program was compared with established andragogical adult education techniques. Results indicated that each curriculum varied in content and method of instruction, although there were many areas of overlap. Suggestions for curriculum selection criteria are …

Lip Kinematics In Spasmodic Dysphonia Before And After Treatment With Botulinum Toxin, Christopher Dromey, Aubrey Reese, Susan Howey

Faculty Publications

In order to learn about articulatory behavior in adductor spasmodic dysphonia (SD), the lip movements of seven individuals with SD and three control speakers were recorded with strain gauges as they repeated 'Buy Bobby a puppy' in voiced and whispered conditions. Results included weaker bilabial coordination, qualitative differences in the shape of lip movement profiles, and an increased number of lip velocity peaks in the speakers with SD. These participants received percutaneous botulinum toxin injection to the thyroarytenoid muscle, and were then recorded again. The pre- vs. post-treatment data revealed that improved vocal activity was associated with fewer articulatory disturbances. …
