Measures Of Acoustic Reflexes In Typically Developing Children And Children With Suspected Auditory Processing Disorder, Udit Saxena

Electronic Thesis and Dissertation Repository

A series of studies were conducted to examine the acoustic reflex in normal hearing adults, typically developing children and children with suspected auditory processing disorder (APD). Elevated acoustic reflex thresholds (ART) and shallower acoustic reflex growth functions (ARGF) were found in children with suspected APD in comparison to typically developing children and normal hearing adults. These effects were strongest in the crossed condition. There were no group differences for acoustic reflex latency (ARL) or acoustic reflex decay (ARD).

In all studies the children with suspected APD were divided into two groups based on the diagnosis made on the basis of …

Epithelial Cells Are Active Participants In Vocal Fold Wound Healing: An In Vivo Animal Model Of Injury, Ciara Leydon, Mitsuyoshi Imaizumi, Rebecca S. Bartlett, Sarah F. Wang, Susan L. Thibeault

Communication Disorders Faculty Publications

Vocal fold epithelial cells likely play an important, yet currently poorly defined, role in healing following injury, irritation and inflammation. In the present study, we sought to identify a possible role for growth factors, epidermal growth factor (EGF) and transforming growth factor-beta 1 (TGFβ1), in epithelial regeneration during wound healing as a necessary first step for uncovering potential signaling mechanisms of vocal fold wound repair and remodeling. Using a rat model, we created unilateral vocal fold injuries and examined the timeline for epithelial healing and regeneration during early and late stages of wound healing using immunohistochemistry (IHC). We observed time-dependent …

The Effect Of Hearing Impairment On Word Processing Of Infant- And Adult-Directed Speech, Velma Sue Robertson

Theses and Dissertations (ETD)

Objective. Little is known about how children with hearing loss (CHL) process words. The Emergent Coalition Model (ECM) of early word learning proposes that multiple cues (e.g., perceptual, social, linguistic) are used to facilitate word learning. Because hearing loss influences speech perception, different word learning patterns may emerge in CHL relative to children with normal hearing (CNH). One perceptual cue used by young children to access word learning is infant-directed-speech (IDS). Specifically, twenty-one month-olds can learn words in IDS but not in adult directed speech (ADS); however, by 27 months children can learn words in ADS. Currently, it is unknown …

Mapping The Spatial And Temporal Dynamics Of Sensorimotor Integration During The Perception And Performance Of Wallowing, Megan E. Cuellar

Theses and Dissertations (ETD)

Similar to other complex sequences of muscle activity, swallowing relies heavily upon ‘sensorimotor integration.’ It is well known that the premotor cortex and primary sensorimotor cortices provide critical sensorimotor contributions that help control the strength and timing of swallowing muscle effectors. However, the temporal dynamics of sensorimotor integration remains unclear, even when performed normally without neurological compromise. Recent advances in EEG analysis blind source separation techniques via independent component analysis offer a novel and exciting opportunity to measure cortical sensorimotor activity in realtime during swallowing, concurrently with muscle activity during swallow initiation. In the current study, mu components were identified, …

Dynamic Channel Allocation Technique For Distributed Multi-Radio Multichannel Multi-Path Routing Protocol In Wireless Mesh Networks, Innovative Research Publications Irp India, Shreenidhi. P.L, Ranganath H R, Puttamadappa C, Basavaraju T G

Innovative Research Publications IRP India

Wireless Mesh Networks (WMNs) have gained main attraction in providing flexible network services and support to the end users. There are many efforts seen to design robust routing protocol for WMNs and solutions are proposed to standardized channel allocation techniques. There are various approaches dedicated to maximize the network though put and minimize network interface. Existing multi radio multi channel routing protocols utilize only single channel situation and static channel allocation degrades the performance of the WMNs. The challenge is to allocate channel without link interference and to improve end-to-end throughput efficiency in multipath routing for WMNs. In this paper, …

Independent Study Project (ISP) Collection

The purpose of this paper is to provide insight on the community model of rehabilitation for individuals with mental health disorders in Chile with a specific focus on schizophrenia. Stigmas surrounding mental health are still very prevalent in this society. These stigmas make it difficult for patients to integrate themselves into society, and in turn, add stress to the patients’ families, who must support and care for them. The community model of mental health rehabilitation is important to consider in the efforts to re-integrate these patients into society. La Corporación Bresky, a rehabilitation center in Peñablanca, will be used as …

Classroom Amplification: The Necessity Of Sound-Amplification In The Classroom, Kalley Ellis

Undergraduate Honors Capstone Projects

In a classroom, the optimal signal-to-noise ratio, as is recommended by the American Nation Standards Institute (ANSI), is 35 dBA, with the reverberation reaching a maximum of 0.6s (Lewis, 2008); yet, in classrooms today, the typical signal-to-noise ratio ranges from 40-73 dBA (Lewis, 2008). With at least 75% of the school day being spent in listening activities (e.g. reading, instructions, lecture, etc.), this noise level in the classroom has great impact on what a child hears and, thus, learns (Blazer, 2008). Unfortunately, with each new year, classroom sizes are increasing and creating an even more detrimental noise level and signal-to-noise …

The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Vietnamese bisyllabic and monosyllabic word lists for use in the measurement of speech recognition and word recognition ability, respectively. To create the speech recognition threshold materials, common Vietnamese bisyllabic words were digitally recorded by male and female talkers of Vietnamese and presented for evaluation to 20 native speakers of Vietnamese with normal hearing. …

Language Pathways Defined In A Patient With Left Temporal Lobe Damagesecondary To Traumatic Brain Injury: A Qeeg & Mri Study, Janelle Lee Bailey

Theses and Dissertations

Though the current understanding of language processing is incomplete, it has been established that the left hemisphere is dominant for language in the majority of the population. Damage to language centers of the brain and to white matter tracts connecting these language centers results in a language deficit known as aphasia. Neuroplasticity in the brain can often compensate for these language deficits by strengthening neuronal connections between the right and left hemisphere, or by enhancing the neuronal connectivity of undamaged areas in the left hemisphere. Thus the brain can compensate for damaged language centers by using alternative cortical areas. These …

Differences In Symptoms Among Adults With Canal Versus Otolith Vestibular Dysfunction: A Preliminary Report, Lisa Farrell, Rose Marie Rine

Rose Marie Rine P.T., Ph.D.

Despite the importance of symptomatology in the diagnosis of vestibular dysfunction, the qualitative nature of the symptoms related to semicircular canal (canal) versus otolith dysfunction is not fully understood. The purpose of this study was to compare symptoms, and their severity, in individuals with canal versus otolith peripheral vestibular dysfunction. A subjective tool, the Descriptive Symptom Index (DSI), was developed to enable categorization of symptoms as rotary, linear, imbalance or falls, and nondistinct. Fourteen adults were recruited and grouped based on vestibular function testing: canal only dysfunction, otolith only dysfunction, or canal and otolith dysfunction. Also, the Dizziness Handicap Inventory …

Word Recognition In Noise Among Young And Older Listeners: A Combined Behavioral And Electrophysiological Study, Victoria Ann Williams-Sanchez

USF Tampa Graduate Theses and Dissertations

Word recognition is based on the complex interplay of bottom up processing of acoustic input and corresponding top-down processing based on linguistic redundancies (i.e., contextual cues). Friedrich and Kotz (2007) investigated the timeline of integrating top-down and bottom-up processes among young adults with normal hearing using sentences presented in quiet. As a follow-up study, also with young adults with normal hearing (Experiment 1 of this dissertation), we used sentences embedded in multi-talker background noise and found similar results to Friedrich and Kotz (2007); but, with the use of principal component analysis (PCA) unveiled additional effects of phonological and semantic integration …

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 …

Vocal Fold Epithelial Barrier In Health And Injury: A Research Review., Elizabeth E. Levendoski, Ciara Leydon, Susan L. Thibeault

Communication Disorders Faculty Publications

Purpose: Vocal fold epithelium is composed of layers of individual epithelial cells joined by junctional complexes constituting a unique interface with the external environment. This barrier provides structural stability to the vocal folds and protects underlying connective tissue from injury while being nearly continuously exposed to potentially hazardous insults, including environmental or systemic-based irritants such as pollutants and reflux, surgical procedures, and vibratory trauma. Small disruptions in the epithelial barrier may have a large impact on susceptibility to injury and overall vocal health. The purpose of this article is to provide a broad-based review of current knowledge of the vocal …
