Intelligibility And The Sinewave Speech Carrier Phrase Effect, 2012 Western Michigan University
Intelligibility And The Sinewave Speech Carrier Phrase Effect, Danielle R. Werle
Several studies have examined the perception of sinewave speech. Early work showed that listeners could transcribe sinewave sentences. Recent work on sinewave vowels found that listeners could recognize sinewave speech at the phonetic level with moderate (about 50-55%) accuracy. Sinewave vowel intelligibility scores improve significantly when preceded by a sinewave carrier phrase, an effect that disappears when the carrier phrase is removed. The present study was designed to examine this carrier phrase enhancement effect and analyze whether listeners require the carrier phrase to be intelligible to produce increased intelligibility scores. Sinusoidal carrier phrases and /hVd/ syllables were generated from recordings …
The Effect Of Early Cochlear Implantation On Oral Language: A Review Of The Literature, 2012 Western Michigan University
The Effect Of Early Cochlear Implantation On Oral Language: A Review Of The Literature, Nicole Supplee
Current research suggests that implantation of cochlear implants before 2 years of age significantly impacts oral language development, specifically in increased rate of oral language development. In addition, children who have been implanted early (between 12 months and two years) have been shown to obtain age-appropriate language skills, whereas children who have been implanted later (after 2 years of age), or not implanted at all, do not. Because of the documented benefits of early implantation, researchers have recently pushed to lower the current minimum age of implantation to below 12 months of age. Although research suggests improvements in language development …

Communication Disorders Faculty Publications
Introduction: Velo-cardio-facial syndrome (VCFS) has been identified as an important risk factor for psychoses, with up to 32% of individuals with VCFS developing a psychotic illness. Individuals with VCFS thus form a unique group to identify and explore early symptoms and biological correlates of psychosis. In this study, we examined if cortical gyrification pattern, i.e. gyrification index (GI) can be a potential neurobiological marker for psychosis.
Method: GIs of 91 individuals with VCFS were compared with 29 siblings and 54 controls. Further, 58 participants with VCFS, 21 siblings and 18 normal controls were followed up after 3 years and longitudinal …
Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, 2012 University of Nebraska Medical Center
Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford
Special Education and Communication Disorders Faculty Publications
Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined.
Methods: The authors recorded word productions from 11 individuals with ALS with mild, moderate, and severe dysarthria using an x-ray microbeam during word productions. A coupling index based on sliding window covariance was used to determine disease-related changes in the coupling between the tongue regions across each word.
Results: The results indicated decreased spatiotemporal coupling of mid-posterior tongue regions and reduced tongue speed …

Speech Pathology and Audiology Faculty Research and Publications
Purpose: The goals of this study were to evaluate the impact of short-term phonological awareness (PA) instruction presented in children's first language (L1; Spanish) on gains in their L1 and second language (L2; English) and to determine whether relationships exist between vocabulary size, verbal working memory, and PA in Spanish-speaking English language learners (ELLs).
Method: Participants included 25 kindergartners who received PA instruction and 10 controls. A 2-way within-subjects repeated measures multivariate analysis of variance (MANOVA) was conducted to evaluate gains. Relationships between PA gains, Spanish and English vocabulary, and memory, as measured using nonword repetition and experimental …
Spontaneous Recovery In Children With Expressive Language Delay, 2012 Western Michigan University
Spontaneous Recovery In Children With Expressive Language Delay, Jaimie Sierakowski
By age 2, most children have an expressive vocabulary of approximately 200 words and begin to combine these words into meaningful phrases. However, some children acquire expressive language skills more slowly than others while displaying no signs of cognitive, receptive, or sensory delays. These children who experience an expressive language delay are often characterized in the literature as late talkers. Research shows that many of these children have delays early in childhood, but eventually catch up to their typically-developing peers, with no need for language intervention. Others, however, continue to experience expressive delays and. have an increased risk of developing …

Let's Talk Speech! Volume 5 Issue 1, Barbara T. Schmidt Ph.D.
Communication Sciences and Disorders Newsletter
The 2011-2012 academic year has been wonderful and full of exciting changes. You are probably all getting tired of hearing me say that each semester! I cannot avoid saying it. We have new full time and part time faculty, great students, plans for an upcoming “relaxation retreat,” an annual scholarship fundraiser, a 2013 trip to Ireland, and so much more. However, as I reflect on the year and the articles that were submitted to the Newsletter, I feel compelled to point out that the SpeechLanguage Pathology Department is facing one major problem: we have too many exceptional students and faculty …
The Effects Of Background Noise On Distortion Product Otoacoustic Emissions And Hearing Screenings, 2012 Louisiana Tech University
The Effects Of Background Noise On Distortion Product Otoacoustic Emissions And Hearing Screenings, Amy E. Hollowell
Hearing screenings are an important tool for identifying children who have, or are at risk for hearing loss in the schools. In light of a body of evidence that demonstrates the effectiveness of objective screening measures, such as otoacoustic emissions (OAEs), the American Speech Language and Hearing Association (ASHA) recommends traditional pure tone audiometric screening as the tool of choice for hearing screenings in the schools. Pure tone audiometric screenings conducted in the schools are problematic for a number of reasons, but the most significant is the presence of background noise which is routinely encountered. The main purpose of the …

Development Of An Elementary School Background Noise, 2012 Louisiana Tech University
Development Of An Elementary School Background Noise, Amanda L. Mccann
The deleterious effects of noise on hearing, comprehension, and academic development have been widely studied. In an effort to accurately observe the effects of noise on specific listening environments, researchers have relied on commercially available forms of background noise. However, these commercially available recordings only contain adult speech and background noises associated with adult environments. A commercially available form of background noise that represents the sounds associated with elementary and middle schools are not readily available. Given that much effort has gone into examining the effects of background noise on classroom performance, it would appear prudent that a background noise …

Asymmetric Directional Microphone Fittings For Individuals With An Asymmetric Hearing Loss, 2012 Louisiana Tech University
Asymmetric Directional Microphone Fittings For Individuals With An Asymmetric Hearing Loss, Jessica White
The present study investigated the effects of asymmetric directional microphone fittings on participants' acceptance of background noise and speech understanding in noise abilities. Thirteen adult, bilateral hearing aid users or non-hearing aid users with bilateral asymmetrical sensorineural hearing loss were fit binaurally with four different microphone conditions (i.e., bilateral omnidirectional, asymmetric directional poorer ear, asymmetric directional better ear, and bilateral directional) and monaurally with two microphone conditions (i.e., unilateral directional better ear and unilateral omnidirectional better ear). The amplification used was a pair of Siemens Intuis directional behind-the-ear hearing aids and comply earmolds.
The results indicated speech understanding in noise …
The Evaluation Of Interhemispheric Transfer Time (Ihtt) In Adults, 2012 Louisiana Tech University
The Evaluation Of Interhemispheric Transfer Time (Ihtt) In Adults, Katherine Elise Cormier
The goal of the present study was to develop an objective technique to measure interhemispheric transfer time (IHTT) of linguistic stimuli using late auditory evoked potentials to develop normative data in adults. Nine participants, five females and four males (M = 25.22) were included in this study. Each participant had their hearing tested and electrodes were placed on the forehead, tip of the nose, below the right eye and several places on the scalp. The results revealed that when comparing electrode sites (CZ, C3, and C4), waves (P1-N1-P2) and ears (right ear and left ear) there was no statistically significant …
Impact Of Noise And Working Memory On Speech Processing In Adults With And Without Adhd, 2012 Old Dominion University
Impact Of Noise And Working Memory On Speech Processing In Adults With And Without Adhd, Anne M. P. Michalek
Communication Disorders & Special Education Theses & Dissertations
Auditory processing of speech is influenced by internal (i.e., attention, working memory) and external factors (i.e., background noise, visual information). This study examined the interplay among these factors in individuals with and without ADHD. All participants completed a listening in noise task, two working memory capacity tasks, and two short-term memory tasks. The listening in noise task had both an auditory and an audiovisual condition. Participants included 38 young adults between the ages of 18-35 without ADHD and 25 young adults between the ages of 18-35 with ADHD. Results indicated that diagnosis, modality, and signal-to-noise ratio all have a main …

Ototoxic Hearing Loss And Retinoblastoma Patients, 2012 University of Memphis
Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat
Chemotherapy is often used in the conservative management of retinoblastoma. Chemotherapy drugs, while ameliorative, can produce long-lasting side effects that potentially can affect survivor quality of life. Carboplatin is a common chemotherapy agent with known ototoxic side effects that is used in the treatment of retinoblastoma (Rodriguez-Galindo et al., 2003). The potential for carboplatin-induced hearing loss is of concern to the medical professional, given that retinoblastoma is often diagnosed in early childhood and children with retinoblastoma have visual impairments. This chapter will outline the mechanisms underlying carboplatin ototoxicity. The extent of knowledge concerning the pathophysiology of carboplatin-induced hearing loss will …
Effect Of Parallel Talk On The Language And Interactional Skills Of Preschoolers With Cochlear Implants And Hearing Aids, 2012 Old Dominion University
Effect Of Parallel Talk On The Language And Interactional Skills Of Preschoolers With Cochlear Implants And Hearing Aids, Sharon A. Raver, Jonna Bobzien, Corrin Richels, Peggy Hester, Anne Michalek, Nicole Anthony
Communication Disorders & Special Education Faculty Publications
Children with profound congenital hearing loss often do not have the same prelinguistic opportunities for social and verbal interaction as their peers with typical hearing . Consequently, language and social skills may be challenging for this group, even after they are provided with amplification or a cochlear implant. This pilot study examined the effectiveness of using a parallel talk intervention to increase the language and interactional skills of three preschoolers with deafnesss. Results revealed that all participants increased verbal turn-taking and that two of the three increased initiated and responded vocal/verbal comments, and initiated and responded nonverbal responses during a …
