Bilingual Language Assessment: Contemporary Practice Versus Recommended Practice, Graciela Arias

Theses and Dissertations

Due to the increasing number of culturally and linguistically diverse students within American school systems, speech-language pathologists (SLPs) in school settings must be prepared to distinguish between typically developing bilingual students and those with language impairments. The purpose of this study was to identify current practices of school-based SLPs for bilingual language assessment and compare them to both American Speech-Language-Hearing Association (ASHA) best practice guidelines, and mandates of the Individuals with Disabilities Education Act (IDEA). The study was modeled to replicate Caesar and Kohler's (2007) study to include a nationally representative sample. While the survey was opened over 400 times, …

Brittany Bernal - Sensorimotor Adaptation Of Speech Through A Virtually Shortened Vocal Tract, Brittany A. Bernal

Ronald E. McNair Scholars Program 2014

The broad objective of this line of research is to understand how auditory feedback manipulations may be used to elicit involuntary changes in speech articulation. We examine speech sensorimotor adaptation to supplement the development of speech rehabilitation applications that benefit from this learning phenomenon. By manipulating the acoustics of one’s auditory feedback, it is possible to elicit involuntary changes in speech articulation. We seek to understand how virtually manipulating participants’ perception of vowel space affects their speech movements by assessing acoustic variables such as formant frequency changes. Participants speak through a digital audio processing device that virtually alters the perceived …

Current Steering And Electrode Spanning With Partial Tripolar Stimulation Mode In Cochlear Implants, Ching-Chih Wu

Open Access Dissertations

Cochlear implants (CIs) partially restore hearing sensation to profoundly deaf people by electrically stimulating the surviving auditory neurons. However, CI users perform poorly in challenging listening tasks such as speech recognition in noise and Cochlear implants (CIs) partially restore hearing sensation to profoundly deaf people by electrically stimulating the surviving auditory neurons. However, CI users perform poorly in challenging listening tasks such as speech recognition in noise and music perception, possibly due to the small number of implanted electrodes and the large current spread of electric stimulation. Although current spread may be reduced using partial tripolar (pTP) stimulation mode, the …

Clinical Implications Of Binaural Interference: A Systematic Review Of The Literature, Michael Bergen

Dissertations, Theses, and Capstone Projects

A binaural advantage has been described in many studies over the past fifty years, although research also has demonstrated examples of a disadvantage known as binaural interference. The literature varies greatly in suggesting the incidence of binaural interference across all populations. It also raises questions about the underlying causes of this phenomenon, as well as whether age-related changes have an impact.

A systematic review was engaged to summarize the literature associated with binaural interference, to identify clinical implications of this body of literature, and to answer two research questions:

1) Does the literature describe changes in susceptibility to binaural interference …

The Status Of Neonatal Hearing Screening In Sub-Saharan Africa: A Systematic Review, David Engelman

Dissertations, Theses, and Capstone Projects

Late identification of hearing loss can lead to speech and language delays, as well as social and academic difficulties. Neonatal hearing screening has reduced the age of identification of hearing loss in many developed countries. However, the practice is limited or non-existent in much of the developing world, such as sub-Saharan Africa. This systematic review used currently available literature to determine the status of neonatal hearing screening programs in sub-Saharan Africa and to develop a model program for the region. Results suggested a lack of neonatal hearing screening services in sub-Saharan Africa, stressing the need for more pilot hearing screening …

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

Underprivileged Children In Port-Au-Prince, Haiti: Hearing And Academic Performance Of Children In Public Schools In Port Au Prince, Talia Meisel

Dissertations, Theses, and Capstone Projects

Hearing loss is estimated to affect more than 360 million people worldwide, 32% of whom are children. Children with hearing loss tend to develop compromised communicative abilities and also have been found to perform more poorly academically than their normal hearing peers. Because of the lack of medical care, children in third world countries are expected to have more difficulty hearing and learning in a classroom setting than children in first world countries due to higher incidences of conductive pathology. The purpose of this study is to assess the hearing ability of underprivileged children in kindergarten and primary schools in …

Palate-Referenced Articulatory Features For Acoustic-To-Articulator Inversion, An Ji, Michael T. Johnson, Jeffrey J. Berry

Speech Pathology and Audiology Faculty Research and Publications

The selection of effective articulatory features is an important component of tasks such as acoustic-to-articulator inversion and articulatory synthesis. Although it is common to use direct articulatory sensor measurements as feature variables, this approach fails to incorporate important physiological information such as palate height and shape and thus is not as representative of vocal tract cross section as desired. We introduce a set of articulator feature variables that are palate referenced and normalized with respect to the articulatory working space in order to improve the quality of the vocal tract representation. These features include normalized horizontal positions plus the normalized …

Consonant Context Effects On Vowel Sensorimotor Adaptation, Jeffrey J. Berry, John Jaeger Iv, Melissa Wiedenhoeft, Brittany A. Bernal, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Speech sensorimotor adaptation is the short-term learning of modified articulator movements evoked through sensory-feedback perturbations. A common experimental method manipulates acoustic parameters, such as formant frequencies, using real time resynthesis of the participant's speech to perturb auditory feedback. While some studies have examined phrases comprised of vowels, diphthongs, and semivowels, the bulk of research on auditory feedback-driven sensorimotor adaptation has focused on vowels in neutral contexts (/hVd/). The current study investigates coarticulatory influences of adjacent consonants on sensorimotor adaptation. The purpose is to evaluate differences in the adaptation effects for vowels in consonant environments that vary by place and manner …

Reliability Of Two Alternative Methods For The Standard Mid-Thigh Isometric Pull, Duane A. Williams, Courtney D. Hall, Patsy Cantor, Jennifer Williams, N. Brown, Ryan Dulling, Ogechi Egbujor

ETSU Faculty Works

The purpose of this study was to determine the reliability of two new alternative portable methods for measuring maximal isometric force measures while performing the standard mid-thigh pull. One method, the bar grip method, required the use of the trunk and upper extremity muscles, while the second method, the pelvic belt method, did not. Both methods demonstrated good test-retest reliability via randomized repeated measures over 24-36 hours. Interestingly, the pelvic belt method generally demonstrated average maximal forces up to 65% higher than the bar method. There was a good relationship between both methods. These new alternative methods could provide strength …

Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat

Faculty Publications

Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. This hypothesis was directly tested by measuring both forward- and simultaneous-masked psychophysical tuning curves. Sharper filter tuning (i.e., higher Q10) was observed in musicians compared to nonmusicians. Findings suggest musicians' pervasive listening benefits may be facilitated, in part, by superior spectral processing/decomposition as early as the auditory periphery.

Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston

Open Access Theses

Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …

The purpose of the present study was to compare attitudes towards noise between undergraduate speech-language pathology/audiology majors and other majors. Participants (N = 119) responded to a survey used to compare attitudes toward noise in the two groups, as well as their perceived ability to influence their sound environment. In addition, a correlational analysis was performed to determine if a relation exists between attitudes towards noise and attitudes towards influencing one's sound environment. Findings …

A Review Of Animal Studies For The Efficacy Of D-Methionine In Reducing Threshold Shifts And Affecting Biochemical Changes After Exposure To Noise, Alexandra Petraru

Dissertations, Theses, and Capstone Projects

Noise induced hearing loss (NIHL) is a major public health concern in the United States and worldwide. Certain individuals such as factory workers and military personnel are at greatest risk for irreversible sensorineural hearing loss due to the limitations of hearing protection measures and devices. D-Methionine (d-Met) is an antioxidant otoprotective agent that currently is in human clinical trials. The purpose of this systematic literature review was to review d-Met’s efficacy in reducing threshold shifts as well as in producing biochemical and physical changes in animal studies vis-à-vis the administration paradigm (preloading, rescue and a combined approach), d-Met dose quantity …
