Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford

Department of 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 …

Relationships Between Vocabulary Size, Working Memory, And Phonological Awareness In Spanish-Speaking English Language Learners, Brenda K. Gorman

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 …

Cortical Gyrification In Velo-Cardio-Facial (22q11.2 Deletion) Syndrome: A Longitudinal Study, Arun Kunwar, Seethalakshmi Ramanathan, Joshua Nelson, Kevin M. Antshel, Wanda Fremont, Anne Marie Higgins, Robert J. Shprintzen, Wendy R. Kates

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 …

Spontaneous Recovery In Children With Expressive Language Delay, Jaimie Sierakowski

Honors Theses

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 …

Nonword Repetition And Interactions Among Vocabulary, Phonotactic Probability, And Phonological Awareness In Four Linguistic Groups, Sue Ann S. Lee, Brenda K. Gorman

Speech Pathology and Audiology Faculty Research and Publications

The current study was designed to compare the English nonword repetition accuracy in 7-year-old monolingual English, Korean–English bilingual, Chinese–English bilingual, and Spanish–English bilingual children. The relationships among nonword repetition accuracy, vocabulary, phonological awareness, and phonotactic probability in each group of children were also examined. The results indicated significant differences among the groups’ accuracy of consonants and vowels by syllable length. Different correlational patterns emerged among nonword repetition accuracy, vocabulary, and phonological awareness. Theoretical and clinical implications for the use of nonword repetition tasks for children from various linguistic backgrounds are discussed.

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 Evaluation Of Interhemispheric Transfer Time (Ihtt) In Adults, Katherine Elise Cormier

Doctoral Dissertations

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 …

The Effects Of Background Noise On Distortion Product Otoacoustic Emissions And Hearing Screenings, Amy E. Hollowell

Doctoral Dissertations

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, Amanda L. Mccann

Doctoral Dissertations

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 …

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, Shaum Bhagat

Faculty Publications

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, 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 [14]. 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 …

The Pacific Assessment Of Confabulation, Larry Boles

School of Pharmacy Faculty Presentations

This paper presents data on the Pacific Assessment of Confabulation (PAC), which was designed to accomplish two goals. First, the PAC is intended to quantify confabulation. Confabulation has been described as dichotomous (i.e., present or absent), without attempts to quantify it. A second goal is to test the hypothesis that occurs in the normal population. Literature related to witness testimony suggests this may be true.
