The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer

Arts & Sciences Graduate Student Theses and Dissertations

The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …

Word Error And Word Frequency Correlation In Broca’S Aphasia, Breawna Heal

Honors Projects

Aphasia is a language disorder that is caused to the brain (Shames, Wiig, Secord, 1998) This damage may be caused by a stroke, traumatic brain injury, lesions to the brain, or degenerative neurological diseases(Shames, Wiig, Secord, 1998). Depending on the location of the brain damage, a person with aphasia will present with different communication impairments. People with fluent aphasia produce speech that may feature many grammatical errors or incorrectly produced words but their speech retains a typical speaking rhythm. People with fluent aphasia’s speech is much slower and more halting, and there tends to be frequent and lengthy pauses between …

Auditory Verbal Hallucinations In Schizophrenia, Katherine Joiner

Honors Theses

The primary auditory cortex being linked to the AVHs could be due to it being overly sensitive when being stimulated by processing found internally, opposing to outward stimulation. The 173 individuals who were available for both structural data and resting state, 83 were found to have schizophrenia or schizoaffective. Resting state echo planar image (EPI) volumes had 32 slices of 4mm 64x64 matrix with 4mm thickness (voxel size = 3x3x4mm), with repetition time (TR) of 2000ms and echo time (TE) of 29ms. A total of 150 volumes (5 minutes) were used in the analysis. The auditory cortex in the SZ …

Feeding Outcomes In Children With Craniofacial Anomalies, Meghan R. Hansen, Shannon M. Theis, Deanna Britton

Student Research Symposium

Feeding disorders in children with craniofacial anomalies, specifically cleft lip and/or palate, have been documented in the literature as a source of parental stress and can lead to difficulties with the early parent-infant bonding process, as well other medical co-morbidities including poor growth, impairment to the respiratory and developmental health of the child, and increased hospitalizations (Miller, 2011). However, there is a dearth of information in the literature regarding atypical craniofacial anomalies and early feeding difficulties. By utilizing an interdisciplinary team approach, we present a series of three case studies of early feeding difficulties in children with varying degrees of …

Socialsibs: The Effects Of A Hybrid Intervention On The Core Social Communicative Behaviors Of Children With Asd, Marissa Montejano

Student Research Symposium

Purpose/Introduction
Social communication challenges are a central feature of autism spectrum disorders (ASD; APA, 2013). Social communication skills are often a key focus of intervention; however, generalization of skills to natural contexts, particularly peer relationships is a challenge for many children on the spectrum (Ferraioli & Harris, 2011; Schreiber, 2011; Wang & Spillane, 2009).

Socialsibs is a hybrid intervention that targets social interaction, communication, and reciprocity using a combination of video modeling and sibling-mediation within a naturalistic behavioral framework. The intervention was examined within a waitlist control design study with children with ASD and their neurotypical siblings. The current poster …

An Ocean Of Brain Waves: Analyzing Methods To Find Erp Signals In The Noise, Andrea Hamblen, Mallary Owen, Lindsay Robb, Susan Wiggins, Sarah Key-Delyria

Student Research Symposium

Questions:
Will the N400 ERP be observed when participants read word pairs that are either related (semantically, causally, hierarchically, or associatively) or unrelated?

Will a replication of a study using word pairs with varying degrees of relatedness produce similar results to the model study in terms of N400 latency and amplitude?

Can results from a robust, easily-recognizable ERP be used to validate methods for the discovery of more subtle ERP’s?

Hypotheses:

It is expected that our results will mirror the findings of our model study, revealing significant negative-going neural activity between 200 and 500ms after seeing the stimulus. We anticipate …

Cross-Language Transfer In Intervention With Bilingual Adults Who Stutter: Two Case Studies, Marlen Castellanos, Hillary Landers, Megann Mcgill

Student Research Symposium

Attrition Effects In Mandarin-English Bilinguals Of Varying Proficiency, Sarah Elkinton, Jared Forman, Diana Yuen, Carolyn Quam

Student Research Symposium

Previous research has shown that English dominance caused an attrition effect in tone processing in native Mandarin speakers (Quam & Creel, 2017). There were two explanations offered, either tones are more prone to attrition because of their unique mental representation, or English dominant bilinguals are able to recruit English perceptual categories to process the Mandarin vowels. This research project is a verification and expansion of that research investigating how dominance in English, a non-tonal language, impacts lexical tonal processing in Mandarin for Mandarin-English bilinguals. This research project is testing the robustness of this effect in two ways. The first is …

Bilingual Adults With Tbi And Abi: Current State Of Portland Metro Slp Assessment Resources, Sarah Shellard, Sarah Key-Delyria

Student Research Symposium

This study aims to identify the extent and nature of available resources in inpatient, outpatient, and rehabilitation settings for speech-language assessment and treatment in Spanish-speaking adults with traumatic brain injury (TBI) and acquired brain injury (ABI) in the Portland Metro area. Identification of lack of resources could be used for future improvements in resources. To investigate this, a web-based survey was answered by 25 participants via Qualtrics. Participants were speech-language pathologists (SLPs) in the Portland metro area who have treated bilingual / multilingual clients in the past 1-2 years.

Results are presented descriptively to answer four research questions: (1) Have …

Participant Accuracy And Impact Of Biofeedback On A Skilled Swallowing Task, Caris Giessler

Senior Honors Projects, 2010-2019

Biofeedback is as a visual way to self-assess muscle contraction, particularly during rehabilitative exercises. Speech language pathologists and otolaryngologists have investigated the use of visual biofeedback in swallowing therapy, especially for volitional swallowing rehabilitative exercises such as the effortful swallow, which requires the patient to maximally swallow with all their strength. In contrast to the effortful swallow, “effortful skilled swallowing” is the ability to swallow with a specific and precise amount of effort, which is an emerging topic in dysphagia research. Dysphagia, also known as disordered swallowing, can be an organic congenital disorder treated via feeding tubes, or an acquired …

Cervical Vestibular-Evoked Myogenic Potentials (Cvemps): "Differentiation Of Inter-Neck Emg Symmetry Between Children And Adults", Ellen Jones

Senior Honors Projects, 2010-2019

A cervical Vestibular-Evoked Myogenic Potential (cVEMP) is one of the few objective vestibular diagnostic tests available for pediatric populations. This test evaluates the functionality of the saccule end organ through an inhibitory reflex on the sternocleidomastoid (SCM) muscle that inhibits the level of electromyographic (EMG) activity (Wiener-Vacher, 2013). Because the saccule response is measured as an inhibition of EMG in the SCM, it is imperative that the SCM have a tonic contraction prior to eliciting the response and that the contraction of the SCM is equal on the right and left sides. It is generally accepted that young, healthy adults …

American And British Speech Differences In Low Socioeconomic Status Homes, Jennifer Markfeld

Senior Honors Projects, 2010-2019

Background: Infants living in low socioeconomic status (SES) homes display lower developmental functioning by 12 months than mid- and high-SES infants, and speak fewer words on average as they grow older. Maternal speech is especially important for language development and has been found to be the largest predictor of SES-related differences in children’s vocabulary. Although there are documented differences between British and American infant language development, for example American infant lexicons are typically larger than age matched British infants, there is little research looking at caregiver speech across these countries in low SES groups.

Method: This retrospective study compared 10 …

The Feasibility Of Standardized Cognitive Assessments For Vestibular Patients, Brynn Morales

Senior Honors Projects, 2010-2019

Vestibular dysfunction, or impairments in the inner ear and/or brain structures that process sensory information and help control balance, has a high correlation with cognitive deficits, or problems with mental processes. This relationship negatively affects daily activities and quality of life in persons that live with vestibular dysfunction. Though there is sufficient research proving the relationship, few studies have applied that information in ways to better help the population with vestibular dysfunction. The purpose of this study was to assess the feasibility of a cognitive assessment battery (a set of correlated assessments delivered in one session) tailored to measuring performance …

Do Emg Monitoring And Amplitude Normalization Reduce Cvemp Variability In A Pediatric Population?, Brenna Murray

Senior Honors Projects, 2010-2019

Untreated balance disorders can cause anxiety, social withdrawal, and even slow motor development in children, making early and accurate diagnosis crucial to patient care. One of the leading tests for the diagnosis of balance disorders is known as the cervical vestibular evoked myogenic potential (cVEMP) test. The cVEMP test is the only clinically available tool that assesses the integrity of the organ of balance known as the saccule and its afferent pathway through the inferior vestibular nerve. The test is noninvasive and easy to administer, making patient diagnosis quick and effective rendering it crucial in the assessment of vestibular function …

Examining The Effectiveness Of Interprofessional Collaboration For Preprofessional Speech-Language Pathology And Occupational Therapy Graduate Students, Morgan Cornwell

Senior Honors Projects, 2010-2019

This study explores the effects of an emergent writing interprofessional collaboration experience for preprofessional speech-language pathology (SLP) and occupational therapy (OT) graduate students. The preprofessionals were split into two groups (SLP only and SLP-OT pairs) and delivered emergent writing interventions to preschoolers either individually (SLP only) or collaboratively (SLP-OT pairs). The purpose of this study was to investigate how working collaboratively versus working individually to deliver the interventions to preschoolers influences the preprofessionals’ knowledge of theInterprofessional Education Collaborative’s (IPEC) core competencies and emergent writing concepts. The results showed that paired preprofessionals reported higher levels of interprofessional competency than unpaired preprofessionals. …

Subjective Differences Between Premium And Mid-Level Digital Hearing Aids, Dakota Sharp

Dissertations, 2014-2019

This study compared perceptual differences between premium and mid-level hearing aids from a major manufacturer in normal hearing listeners. Limited literature currently exists comparing perceptual differences between premium and mid-level digital hearing aids. This information is highly important in decision-making for clinicians and patients alike. Barry et al. (2018) evaluated four major hearing aid models’ noise reduction properties and determined that one manufacturer’s premium and mid-level devices demonstrated significant differences in noise reduction gain in frequencies associated with human speech. We programmed this device for a mild sloping to moderately-severe SNHL using the manufacturer’s proprietary fitting formula and noise reduction …

Music And Speech Perception In Children Using Sung Speech: Effects Of Neurocognitive Factors, Victoria A. André

Dissertations, 2014-2019

The current study aimed to explore normal-hearing children's ability to utilize pitch and timbre cues and how these findings correlate with neurocognitive factors. Participants were recruited if they had English as their first language and no formal musical training or 3+ years of formal musical training. Twenty normal-hearing children, age 7.5-14.5 years (mean = 10.5; n=20) were recruited for the study. Nonverbal intelligence, receptive vocabulary, and auditory working memory were assessed using subtests of the Kaufman Brief Intelligence Test-2, Peabody Picture Vocabulary Test-4, and Comprehensive Test of Phonological Processing-2, respectively. Raw scores were used to analyze these neurocognitive abilities in …

Audiologists’ Preferences In Programming Cochlear Implants, Leanne Browning

Dissertations, 2014-2019

Cochlear implants have become a viable option for those with severe to profound sensorineural hearing loss who gain little benefit from hearing aids and have poor word recognition ability. However, the techniques audiologists use to program these devices are not standardized (Sorkin, 2013). There is little data available which analyzes how audiologists handle clinical cochlear implant programming between the top manufacturers. These companies supply default settings in their products but is it unknown how often audiologists use these in practice in the United States.

In the present study, a questionnaire based on previous European data from Vaerenberg et al. (2014) …

Voice Quality As A Predictor Of Dysphagia, Lindsay Griffin

Dissertations, 2014-2019

The clinical swallowing evaluation (CSE) is a non-instrumental exam that informs speech-language pathologists about a patient’s cognition, readiness for instrumental evaluation, and swallowing symptoms. Because of the common neuroanatomy and physiology of the larynx during voicing and swallowing tasks, coughing or throat clearing after food and drink may indicate swallowing impairment. Also because of the shared mechanisms of the larynx, some clinicians also attribute voice changes after swallowing to dysphagia although many studies to date demonstrate conflicting results on the effectiveness of post-prandial voice assessment. The aim of this study was to assess if dysphonia and/or voice change after swallowing …

The Test-Retest Reliability Of Binaural-Processing Tasks At Home Versus A Clinical Environment, Logan Grace Faust

Dissertations, 2014-2019

Objective: Investigate the reliability of a custom-designed, portable, stereo-hearing testing system (as in the Ganev, 2017, Au.D. dissertation) when subjects self-administer two different stereo-hearing tasks at home. Results obtained under known and supervised conditions at a university clinic or lab versus unknown conditions at the participants’ homes were compared. Intra-subject comparison, and inter-subject trends, discerned the reliability of patient setup and self-administration of the two tasks.
Design: Ten subjects were evenly split among two conditions: five subjects each setup and self-administered the tasks first at home and then received direction in the clinic, and five received direction and did the …
