Epidermal Growth Factor Mediated Healing In Stem Cell-Derived Vocal Fold Mucosa, Liliana Palencia, Amritava Das, Sean P. Palecek, Susan L. Thibeault, Ciara Leydon

Communication Disorders Faculty Publications

Background: The goal of vocal fold wound healing is the reconstitution of functional tissue, including a structurally and functionally intact epithelium. Mechanisms underlying reepithelialization in vocal folds are not known, although it is suspected that healing involves the interplay between several growth factors. We used a three-dimensional human embryonic stem cell-derived model of vocal fold mucosa to examine the effects of one growth factor, exogenous epidermal growth factor (EGF), on wound healing. Materials and methods: A scratch wound was created in the in vitro model. Rate of wound healing, epidermal growth factor receptor (EGFR) activation, and cell proliferation after injury …

Increasing Emotion Word Productions In Children With Language Impairment With A Social Communication Intervention, Madelane Kate Dixon

Theses and Dissertations

This thesis examines the efficacy of a social communication intervention in increasing the emotion word productions in school-aged children with language impairment (LI). The study had a multiple baseline single subject design in which 5 children between the ages of 6 and 11 received 20 intervention sessions, each lasting 20 minutes. Intervention activities included reading and discussing children's books, enacting the stories using toys, and journal writing to reflect on experiences in each session. Emotion word productions during intervention sessions were coded for total productions within the categories of happiness, anger, sadness, fear, surprise, and disgust. Productions were also coded …

Short Report: Raising Children Bilingually, Henriette Langdon

Faculty Publications

The purpose of this article is to describe the process of becoming bilingual by sharing my own experience being raised in a four-language environment and how it influenced the upbringing of my daughter in two, and subsequently three languages. The other purpose is to dispel the myth that children with language, developmental and/or intellectual impairments or those diagnosed as being on the autism spectrum cannot or should not be exposed to two languages because it is confusing, or because they simply cannot handle two languages due to their disability. As a bilingual speech and language pathologist (SLP) who has practiced …

Training And Application Of Correct Information Unit Analysis To Structured And Unstructured Discourse, Audrey Bretthauer Cohen

Dissertations and Theses

Correct Information Units (CIU) analysis is one of the few measures of discourse that attempts to quantify discourse as a function of communicating information efficiently. Though this analysis is used reliably as a research tool, most studies' apply CIUs to structured discourse tasks and do not specifically describe how raters are trained. If certified clinical speech-language pathologists can likewise reliably apply CIU analysis within clinical settings to unstructured discourse, such as the discourse of people with aphasia (PWA), it may allow clinicians to quantify the information communicated efficiently in clinical populations with discourse deficits. Purpose: The purpose of this study …

Formant Frequency Transitions In The Fluent Speech Of Adults Who Do And Do Not Stutter: Testing The Over-Reliance On Feedback Hypothesis, Kaitlin Arnold

Masters Theses

A recent theory proposed by Civier and colleagues (Civer et al. 2010; Civer et al. 2013) developed a model of stuttering that implicates a faulty feedforward control system. The hypothesis suggests that stuttering results from relying too heavily on sensory feedback to guide speech movements. An overreliance on sensory feedback would result in subtle anomalies in fluent speech (such as slowed articulatory transitions) as well as overt stuttering behaviors (such as sound repetitions). The present study tested this general hypothesis by comparing articulatory transition rates of adults who do and do not stutter across casual and fast speech rates. Participants …

Automated Grammatical Tagging Of Clinical Language Samples With And Without Salt Coding, Andrea Nielson Hughes

Theses and Dissertations

Language samples are naturalistic sources of information that supersede many of the limitations found in standardized test administration. Although language samples have clinical utility, they are often time intensive. Despite the usefulness of language samples in evaluation and treatment, clinicians may not perform language sample analyses due to the necessary time commitment. Researchers have developed language sample analysis software that automates this process. Coding schemes such as that used by the Systematic Analysis of Language Transcripts (SALT) software were developed to provide more information regarding appropriate grammatical tag selection. The usefulness of SALT precoding in aiding automated grammatical tagging accuracy …

Establishing Normative Data For Contact Patterns Of Fricative Production By Native German Speakers: An Electropalatography Study, Lisa Diane Isaacson

Theses and Dissertations

Electropalatography (EPG) provides real-time visual biofeedback for linguapalatal contact during speech and swallowing. Historically, EPG has proved to be an effective tool for assessment and treatment of a variety of speech disorders across a wide age range. The present thesis is part of a larger study examining the effectiveness of using EPG in assisting second language (L2) learners to acquire the German fricatives , [x], and //. Real and nonsense word productions were collected from six native German speakers. Electrode activation levels were generally highest for and lowest for [x]. Even when considering the impact of vowel context, [x] consistently …

Attitudes Of Normal Hearing Listeners Towards Personal Sound Amplification Products: Etymotic Bean, Jennifer Rhoades

Dissertations, Theses, and Capstone Projects

Despite the remarkable prevalence of hearing loss in the United States, only a small percentage of these individuals utilize hearing aids. Many factors have been associated with the non-adoption of hearing aids, including financial reasons and the stigma associated with hearing aid use. Personal sound amplification products (PSAP) have been recently introduced as a more discrete and less costly type of assistive listening technology. While the Food and Drug Administration does not approve these devices for individuals with hearing loss, they are advertised as being useful for boosting soft sounds and amplifying speech in the presence of background noise.

Age, Cognition, And Listening Effort, Sapna Mehta

Dissertations, Theses, and Capstone Projects

Older adults are reported to have more difficulty understanding degraded speech than younger adults. This may be due to greater recruitment of cognitive resources in adverse listening conditions. The purpose of this study was to examine the relationship between listening effort as measured by a dual task paradigm and cognitive abilities, specifically, working memory and selective attention, in normal-hearing older and younger adults in various background noise conditions. Results revealed that speech recognition scores were poorer for older adults, and speech recognition scores declined with decreasing signal-to-noise ratio. Stroop test scores suggested better selective attention ability in the younger participants, …

Cochlear Implantation As A Treatment Option For Adults With Post-Lingual Single Sided Deafness: A Systematic Review Of The Literature, Elvera Bader

Dissertations, Theses, and Capstone Projects

Adults with post lingual single sided deafness experience a myriad of issues as a result of their condition. Speech perception in noise and localization are well documented as being compromised in this population due to the loss of binaural auditory input. Cochlear implantation was introduced in the 2000s as an experimental treatment option for suppression/abatement of tinnitus in individuals with SSD, with consistent demonstration in reduction of tinnitus severity. Most recently, the focus has shifted to the potential reintroduction of binaural effects, and subsequently, improvements in speech in noise and localization performance through this treatment modality. The present systematic review …

Attitudes Of Normal Hearing Listeners Towards Personal Sound Amplification Products: Sound World Solutions Cs50, Marisa Viets

Dissertations, Theses, and Capstone Projects

Over 23 million individuals in the United States have some degree of hearing loss but do not own hearing aids. Individuals may choose not to adopt hearing aid technology for an assortment of reasons, including the stigma associated with hearing aids, cost of the devices, or denying the effects of hearing loss. Prevalence of hearing aid usage remains low despite research indicating that untreated hearing loss is correlated with decreased quality of life and accelerated cognitive decline. In recent years, personal sound amplification products (PSAPs) have entered the market as simple, low cost, discreet devices in attempt to reach non-users …

Discerning Between Types Of Otitis Media And Their Evidence Based Treatments: A Review For The Audiologist, Hadassah Norowitz

Dissertations, Theses, and Capstone Projects

Otitis media is an inflammatory pathology of the middle ear and middle ear mucosa which accounts for the majority of cases of childhood hearing loss diagnosed by audiologists. However, considerable confusion exists regarding the distinction between otitis media with effusion, also known as middle ear effusion or “glue ear”, and acute otitis media, the quintessential ear infection. Since many children are referred for audiological evaluation in the process of determining the course of treatment and outcomes of treatment, audiologists must be knowledgeable of the evidence of efficacy for various treatment options as they field questions from parents with incomplete information …

Attitudes Towards Music Levels At Orthodox Jewish Weddings, Evan Hirschhorn

Dissertations, Theses, and Capstone Projects

Noise induced hearing loss is a deficit in the sensorineural part of the hearing mechanism, produced by the damaging effects of overstimulation by high intensity sound levels, usually over a period of time. Much of the noise literature has focused on occupational noise; however, the noise levels measured at non occupational and recreational settings have been found to be notably high as well. Attitudes and behaviors may vary based on demographics as such hearing conservational practices may benefit by honing in on demographic information. In the Orthodox Jewish community, weddings have a central role in community life, attended by many …

Hearing Conservation Attitudes And Behaviors At Orthodox Jewish Weddings, Audrey Margulies

Dissertations, Theses, and Capstone Projects

Previous research has shown that prolonged exposure to noise can cause permanent hearing loss. Noise levels at Orthodox Jewish weddings can reach extremely high and damaging levels, yet the hearing conservation attitudes and behaviors of the attendees are unknown. The objective of this study is to identify the attitudes and behaviors of Orthodox Jewish wedding attendees toward hearing conservation. The major questions are: 1. What are the sound exposure levels at Orthodox Jewish weddings? 2. Do attendees hold positive attitudes toward the need for hearing conservation at Orthodox Jewish weddings? 3. What hearing conservation is being practiced at weddings among …

Mouth Asymmetries During Infant Babbling: A Brain Lateralization Study, Cecilia Breazile

Senior Honors Projects, 2010-2019

Although babbling is both prevalent and important in the process of language development, it could be argued that we still do not understand the basic nature of babbling. To further our understanding of the nature of babbling we attempted to find evidence for brain lateralization typical of adult speech acts during early babbling. This study examined infant mouth asymmetries during babbling sequences in search of evidence that babbling is an inherently linguistic act as indicated by the lateralization of the brain. Previously recorded videos of 12 infants, all 9 months of age, were examined, 29 images were captured, and a …

Evidence-Based Practices In Selecting Standardized Assessments Of Child Language, Darielle Cooper

Senior Honors Projects, 2010-2019

From the results of a survey given to 1,399 speech-language pathologists, 11 frequently used language assessment tools for preschool and school age children were selected to undergo a systematic review. The examiner’s manual of each assessment was examined to determine whether the test reported adequate psychometric properties and acceptable levels of diagnostic accuracy. Results indicated that all reviewed assessments met at least 60% of McCauley and Swisher’s (1984) psychometric criteria for evaluating norm-referenced tests. Six of the 11 assessments provided information on diagnostic accuracy in the examiner’s manual or in the literature. Four tests published acceptable levels of diagnostic accuracy, …

The Effects Of Narrative Elicitation Task On The Verb Morphological Patterns Of Younger Adolescents With And Without Specific Language Impairment, Megan T. Taliaferro

Senior Honors Projects, 2010-2019

Specific language impairment (SLI) is one of the most commonly occurring communication disorders (Castrogiovanni (2008)). SLI is an impairment in the language of children, adolescents and adults who show no other impairment such as mental, emotional or physical problems. Individuals with SLI demonstrate normal intelligence as shown by nonverbal Intelligence Quotient (IQ) scores; however, their language skills appear to be worse than their normally achieving (NA) peers. There has been an issue in identifying individuals with SLI. One factor contributing to the identification issues of SLI is the lack of a clinical marker. Although no clinical marker currently …

Does Vestibular Sensory Stimulation, In The Form Of Slow, Linear Swinging, Change The Modes Of Communication Among Children With Autism?, Katherine A. Gallaher

Senior Honors Projects, 2010-2019

The purpose of this study was to determine if children with autism receiving vestibular sensory stimulation (VSS) in the form of slow, linear swinging, had any change or progression in their modes of communication when compared to children with autism who received a free-play period (nVSS) during speech-language (SL) therapy. Over the course of therapy, each child’s response mode was recorded as a gesture, vocalization, gesture + vocalization, or an utterance, and each mode was a dependent variable (DV) in this study. Participants who received VSS treatment were expected to have a greater improvement on the progression of modes, such …

Quality Of Life Indices In Brain Injury: A Pilot Investigation, Lauren Kristine Maher

Senior Honors Projects, 2010-2019

This IRB approved study explores the scope of acquired brain injury (ABI) as it affects an individual’s perceived quality of life and how measurement informs clinical decisions. Quality of life is an important consideration for persons with ABI, since research indicates acquired brain injury can lead to personality changes such as depression, anxiety, and aggression not previously exhibited (Greve et al., 2001). When treating persons with ABI, healthcare professionals must be able to reliably measure and track their client’s perceived quality of life. This pilot study included 35 clients receiving community-based intervention at Crossroads to Brain Injury Recovery, Inc. (Crossroads) …
