Age-Related Changes In Listening Effort For Various Types Of Masker Noises, Jamie L. Desjardins

Communication Sciences and Disorders - Dissertations

It is well established that older listeners have more difficulty understanding speech in background noise than younger listeners (e.g. Dubno et. al., 1984). Some have attributed this increased difficulty to peripheral hearing loss, while others suggest that older listeners may perceive listening in noise as difficult and effortful because it requires them to exert more cognitive resources (Desjardins et. al., 2009). The purpose of the present study was to directly evaluate the relationship between cognitive function, listening effort and speech recognition for a group of younger and older normal hearing adults, and a group of older adults with hearing impairment, …

Memory And Language: Evidence Of Relationships From Three Studies Of School-Age Children, Michele A. Anderson

Augmentative And Alternative Communication Systems In The Classroom, Helen Angela Mezzomo

Walden Dissertations and Doctoral Studies

Augmentative-alternative communication (AAC) systems are used to give voice to individuals who are nonverbal. As AAC systems become more complex and prevalent in the classroom expectations of school-based professionals expand. However, the roles of those expected to support AAC systems, primarily teachers and speech-language pathologists (SLPs), are not clearly defined. Without clearly defined roles, professionals may not provide needed support to students who use AAC. Dewey's theory of community suggests that role confusion leads to insufficient and ineffective services. The purpose of this cross-sectional quantitative study was to determine how teachers and SLPs view their roles in supporting AAC. The …

The Neural Underpinnings Of Prosody In Autism, Inge-Marie Eigsti, Jillian Schuh, Einar Mencl, Robert T. Schultz, Rhea Paul

Communication Disorders Faculty Publications

This study examines the processing of prosodic cues to linguistic structure and to affect, drawing on fMRI and behavioral data from 16 high-functioning adolescents with autism spectrum disorders (ASD) and 11 typically developing controls. Stimuli were carefully matched on pitch, intensity, and duration, while varying systematically in conditions of affective prosody (angry versus neutral speech) and grammatical prosody (questions versus statement). To avoid conscious attention to prosody, which normalizes responses in young people with ASD, the implicit comprehension task directed attention to semantic aspects of the stimuli. Results showed that when perceiving prosodic cues, both affective and grammatical, activation of …

Unreported Concussion In High School Football Players, Princess Arcelia Puga

Open Access Theses & Dissertations

Recent research in sport-related concussions has begun to reveal more about the specific hazards of high school football. However, the national reports of incidence/prevalence of concussions in this population appear to be inaccurate, because only emergency department (ED) visits are accounted for in reporting the number of concussions sustained in football. Purpose: The purpose of this study was to investigate whether there is a statistically significant difference between the frequencies of concussion reports by athletic trainers (ATC) versus hospital records on concussion in high school football players in El Paso, Texas. Method: A questionnaire was delivered to athletic trainers through …

The article offers eight simple rules that teachers can use to help preschoolers build their vocabularies. It suggests teachers to talk with children to identify topics that interest them. It also recommends teachers to accompany all the routines and activities of the preschool day to enhance the language experience of children. Moreover, it proposes that open-ended questions invites preschoolers to offer lengthier and more detailed responses, thus stimulating their language growth.

Native Language Experience Influences The Topography Of The Mismatch Negativity To Speech, Hia Datta Ph.D., Jason D. Zevin, Urs Maurer, Kara A. Rosania, Bruce D. Mccandliss

Faculty Works: Communication Sciences Disorders

The ability to learn second language speech sound categories declines during development. We examined this phenomenon by studying the mismatch negativity (MMN) to the /r/ – /l/ distinction in native English speakers and learners of English as a second language who are native speakers of Japanese. Previous studies have suggested that the MMN is remarkably plastic when evaluated as a waveform at a central electrode. We replicated this finding: analyses of the MMN at a typical electrode location (Fz) revealed only small, non-significant differences between groups, despite large behavioral differences in the ability to discriminate these sounds from one another. …

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …

Cervical Vascular And Upper Airway Asymmetry In Velo-Cardio-Facial Syndrome: Correlation Of Nasopharyngoscopy With Mra, Avi G. Oppenheimer, Susan Fulmer, Keivan Shifteh, Ja-Kwei Chang, Allan Brook, Alan L. Shanske, Robert J. Shprintzen

Communication Disorders Faculty Publications

Purpose

Velo-cardio-facial syndrome (VCFS), the most common genetic syndrome causing cleft palate, is associated with internal carotid and vertebral artery anomalies, as well as upper airway asymmetry. Medially displaced internal carotid arteries, often immediately submucosal, present a risk of vascular injury during pharyngeal flap surgery for velopharyngeal insufficiency (VPI). We evaluate the frequency and spectrum of cervical vascular anomalies in a large cohort of VCFS patients correlating MRA with nasopharyngolaryngoscopy in detecting at risk carotid arteries. Furthermore, we assess the relationship with respect to laterality between cervical vascular patterns and the asymmetric abnormalities of these subjects’ upper airways.

Intervention Progress In Two Case Studies Of Childhood Apraxia Of Speech, Laura Marie Czernik

Honors Scholar Theses

There is a great amount of controversy surrounding childhood apraxia of speech (CAS). The most prominent issue is focused on the diagnostic criteria of which to utilize for this disorder. Because of this debate, assessment methods, along with intervention techniques, are heavily questioned. This study examines the progress children with characteristics of CAS make during intervention. Furthermore, it seeks to determine if another diagnosis is possible for these children by examining the speech sound errors such children make. Two children with characteristics of CAS were the focus of this study. Data for these children was gathered from client files at …

The Effects Of Asymmetric Directional Microphone Fittings On Acceptance Of Background Noise, Jong Sik Kim

Doctoral Dissertations

The present study investigated the effects of asymmetric directional microphone fittings (i.e., an omnidirectional microphone on one ear and a directional microphone on the other) on speech understanding in noise and acceptance of background noise in 15 full-time hearing aid users. Subjects were fitted binaurally with four directional microphone conditions (i.e., binaural omnidirectional, asymmetric right directional, asymmetric left directional and binaural directional microphones) using Siemens Intuis directional behind-the-ear hearing aids and comply earmolds. The results revealed that speech understanding in noise improved when using asymmetric directional microphones compared to binaural omnidirectional microphone fittings and were not significantly hindered compared to …

Acceptable Noise Levels In Children Ages 10 To 11 Years And 14 To 15 Years, Krystal Sullivan Ware

Doctoral Dissertations

The present study measured acceptance of background noise in 35 children (age 10–11 and 14–15 years) with normal hearing sensitivity. Acceptance of background noise was measured using the acceptable noise level (ANL) procedure. To obtain an ANL, participants' MCL was first obtained using a running story. Then a competing stimulus (i.e., speech babble or speech spectrum noise) was introduced, and the listeners were asked to adjust the level of the background noise to the most he/she could put up with and follow the story for a long period of time. This level was called background noise level or BNL. The …
