Indirect Approaches: A Systematic Review Of Paediatric Dysphagia Interventions, Bianca Piano

Theses : Honours

Background and purpose: Dysphagia can be described as difficulty within the oral, pharyngeal and/or oesophageal phases of deglutition and occurs in approximately 80% of children with developmental disabilities, according to the American Speech and Hearing Association (2015). It occurs when there is impairment to the motor and/or sensory aspects of swallowing, due to a range of disorders affecting the voluntary and reflexive components of deglutition. The ability to swallow safely is essential in preventing medical complications, sustaining life and maintaining social participation. Paediatric interventions can be categorized into three broad approaches; direct, indirect and mixed. At present, two systematic reviews …

A Comparative Acoustic Examination Of Infant Cries: Children At High Risk Versus Low Risk For Autism Spectrum Disorder Development, Ildiko Eva Bruz

Theses : Honours

Background: Early interventions for individuals with Autism Spectrum Disorders (ASD) have shown positive gains in children who enter therapy at a young age. However, commencement of early intervention is often hindered by challenges with diagnosis. Due to the complex nature of ASD, the age of detection can range from 2 years old into adulthood. This highlights the need for methods of early detection. Previous research has found infants at risk for ASD to present atypical cry characteristics, possibly as a result from damage to the brainstem. In particular, measures of fundamental frequency appear to be the most sensitive to …

Early Intervention Of Parent-Infant Interactions In Preterm Infants: A Systematic Review, Stacey Osborne

Theses : Honours

Every year approximately 15 million babies are born preterm. These infants are at an increased risk of language, and other developmental delays due to their immature brain development and higher incidence of brain abnormalities. They also have poorer health outcomes in the early stages of life which may go on to hinder successful parent-infant interactions. Successful parent-infant interactions are important for infant developmental outcomes such as language, cognition and behaviour. While interventions targeting the promotion of positive interactions have been found to have positive effects in a number of populations to date, interactions involving preterm infants have not been explored. …

Enhancing Generalisation In Biofeedback Intervention Using The Challenge Point Framework: A Case Study, Elaine Hitchcock, Tara Mcallister Byun

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Biofeedback intervention can help children achieve correct production of a treatment-resistant error sound, but generalisation is often limited. This case study suggests that generalisation can be enhanced when biofeedback intervention is structured in accordance with a "challenge point" framework for speech-motor learning. The participant was an 11-year-old with residual /r/ misarticulation who had previously attained correct /r/ production through a structured course of ultrasound biofeedback treatment but did not generalise these gains beyond the word level. Treatment difficulty was adjusted in an adaptive manner following predetermined criteria for advancing, maintaining, or moving back a level in a multidimensional hierarchy of …

Validating And Optimizing A Crowdsourced Method For Gradient Measures Of Child Speech, Tara Mcallister Byun, Elaine Hitchcock, Daphna Harel

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

There is broad consensus that speech sound development is a gradual process, with acoustic measures frequently revealing covert contrast between sounds perceived as identical. Well-constructed perceptual tasks using Visual Analog Scaling (VAS) can draw out these gradient differences. However, this method has not seen widespread uptake in speech acquisition research, possibly due to the time-intensive character of VAS data collection. This project tested the validity of streamlined VAS data collection via crowdsourcing. It also addressed a methodological question that would be challenging to answer through conventional data collection: when collecting ratings of speech samples elicited from multiple individuals, should those …

Department of Special Education and Communication Disorders: Faculty Publications

Research about the effectiveness of communicative supports and advances in photographic technology has prompted changes in the way speech-language pathologists design and implement interventions for people with aphasia. The purpose of this paper is to describe the use of photographic images as a basis for developing communication supports for people with chronic aphasia secondary to sudden-onset events due to cerebrovascular accidents (strokes). Topics include the evolution of AAC-based supports as they relate to people with aphasia, the development and key features of visual scene displays (VSDs), and future directions concerning the incorporation of photographs into communication supports for people with …

Examining Barriers With Implementing Augmentative And Alternative Communication In A Midwest School, Ashley Renee Fields

Walden Dissertations and Doctoral Studies

Many speech-language pathologists (SLPs) in a Midwest urban public school system have experienced barriers that prohibit the effective use of augmentative and alternative communication (AAC). The result has left some students with speech language impairments (SLI) without the communication skills for meaningful relationships and success in and out of school. The purpose of this exploratory case study was to determine the perceived barriers of 8 local school SLPs regarding the successful implementation of AAC and their suggestions for addressing the problem. Data were collected from semi-structured interviews with the SLPs. Data collection and analysis were grounded by Ely's conditions of …

Speech-Language Pathologists On Multicultural Counseling Competency, Denise Moore Revel

Walden Dissertations and Doctoral Studies

Despite reports of speech-language pathology graduate-level programs focusing on multicultural competence, the literature suggests speech-language pathologists are not adequately educated and trained to be culturally competent. The purpose of this study was to examine the experiences of public school-based speech-language pathologists' graduate-level academic instruction and the clinical practicum experiences in multicultural competence, specifically in the area of multicultural counseling. Guided by the theory of multicultural counseling and therapy, this study used a phenomenological approach, employing semistructured, in-person interviews with 7 participants. The inclusion criteria used for selecting study participants included: having a master's degree in speech-language pathology, graduation from an …

An Interpretative Phenomenological Analysis Of Caregivers' Support For Their Preschool Children's Language And Social Skills Development, Sheri Stein Blum

Walden Dissertations and Doctoral Studies

Some children have difficulty communicating due to a lack of age-appropriate language and social skills. Researchers have explored how music and language share features that shape language processing. The purpose of this interpretive phenomenological analysis was to explore the experiences of caregivers of preschool children who participated in a music-based program and to understand their perspectives related to children's language and social skill development. Learning style and sensory integration processing theories were used as framework to provide foundations of skills in this study. Research questions addressed caregivers' choices related to this program for their children, their experiences of their children's …

The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

Predicting Protracted Recovery From Sports-Related Concussion Using Computerized Neurocognitive Test Scores And Symptom Cluster Scores, Amanda Sepulveda

Open Access Theses & Dissertations

Background: A previous study showed that symptom evaluation, in conjunction with computerized neurocognitive testing, improved predictions of protracted recovery in a group of male high school football players. The determination of prognosis following sports-related concussion can be used to facilitate return-to-play and academic decision making in concussion management.

Purpose: The purpose of this study was to replicate and extend previous research in determining the accuracy, sensitivity, specificity, and predictive value of computerized neurocognitive test scores and symptom cluster scores in predicting protracted recovery following sports-related concussion.

Study Design: Systematic replication, Cohort study (prognosis)

Methods: 30 concussed collegiate athletes were followed …

A Comparison Of Maze Frequency And Type Across Language And Speaker: A Look At English And Spanish Narrative Retells, Melissa Silver

Open Access Theses & Dissertations

Background: Mazes, as they are referred to in the language literature, are disfluencies that do not add meaning to an utterance including filled pauses, whole word revisions, part word revisions, part word repetitions and whole word repetitions. Extensive research has been conducted on mazes in monolingual and bilingual children, yet the research has not been extended to adults' narrative retell production.

Aims: The current study analyzes monolingual English, monolingual Spanish, and bilingual English and Spanish narrative retells to compare the percent of maze use and type of maze use amongst groups.

Methods & Procedures: The narrative retells of thirty-nine bilingual …

The Effects Of Baby Sign Training On Child Development, Bethany Iris Urquidi

Open Access Theses & Dissertations

Introduction: Baby sign has gained the attention of many researchers and parents. Relatively little is known about the use of baby sign and the impact it has on the development of children. As the use of baby sign increases in popularity, research studies have had limited and inconsistent results regarding its influence. Purpose: The purpose of this study is to measure the effects of baby sign training on the overall development of normally hearing children while improving on the limitations of current studies (between group study). Methods: Participants in the study included 22 children, ages 6 months to 2 years; …

A Comparative Assessment Of Electrophysiological And Behavioral Performance In Individuals With Aphasia Responding To Spoken And Written Sentence Length Commands, Sha-Renae Alexander

Open Access Theses & Dissertations

The aim of this study is to investigate whether deficits in processing affect auditory and reading comprehension in the same manner. This study compared the behavioral and electrophysiologic performance of four individuals with aphasia and four participants with no brain damage responding to spoken and written sentence length commands using a modified version of the Revised Token Test (McNeil & Prescott, 1978). Electrophysiological responses were recorded from the scalp using event related potentials (ERP). The latency and amplitude of the N400 ERP component were measured and analyzed. Behavioral reaction times and correct responses were collected and examined. Performance differences between …

Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …

The Impact Of Accented English On Speech Comprehension, Benigno Valles

Open Access Theses & Dissertations

ABSTRACT

In the context of shifting demographics in the United States and with an increasing multicultural workforce, the verbal exchange of information is vital especially between health care providers and patients. Although English is the official language in the United States, many individuals from different national origins speak English with some degree of accent. Before we can address health care provider/patient communication, it is necessary to investigate the potential impact of accented English on speech comprehension and its implications on basic communicative interactions. The verbal exchange of information between health care providers and patients is important in diagnostics, treatment, patient …

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 …

Behavioral Measures Of Audibility As Indicators Of Hearing Aid Benefit, Bethany Lauren Burkeen

Student Theses and Dissertations

This study investigated the possibility of quantifying hearing aid benefit by means of the Audibility Index. The Audibility Index (AI) is defined as the amount of the audible speech spectrum available to a listener. Twenty-one participants with bilateral sensorineural hearing losses, each required to wear bilateral hearing aids, were recruited for this study. Utilizing FM tone stimuli, audiometric thresholds were established for each individual conventionally under earphones for the right and left ears, unaided in a sound field, and aided in a sound field. The thresholds were placed on a count-the-dot audiogram in order to calculate AIs for each individual. …
