The Effects Of Language Proficiency On Narrative Macrostructure In Spanish-English Bilinguals, Jenny Magallon

Dissertations and Theses

Bilingual children of the same age may have different narrative skills depending on the quantity and quality of their experiences in the two languages. Thus, children's storytelling skills can vary depending on children's oral proficiency in each language. The present study examined the effects of oral proficiency on story structure in forty 5- to 7-year-old Spanish-English speaking children using Spanish and English samples from story retelling tasks. Language proficiency was measured as continuum of performance using the Spanish-English Language Proficiency Scale (SELPS; Smyk et al., 2013). To estimate the effects of Spanish and English proficiency on story structure, linear regressions …

Augmentative And Alternative Communication Use, Service Delivery Experiences, And Communicative Participation For People With Amyotrophic Lateral Sclerosis, Betts Peters

Dissertations and Theses

People with amyotrophic lateral sclerosis (ALS) often experience changes to their speech, and may use augmentative and alternative communication (AAC) devices and techniques to maintain the ability to communicate. The use of AAC may facilitate the participation of people with ALS in various life situations involving communication. There is limited data in the literature about the AAC approaches currently used by people with ALS, the professional services they receive to support communication, or the effects of AAC on their communicative participation. This dissertation involved a nationwide online survey of people with ALS, and comprises three papers intended to add to …

Investigating The Role Of Phonological Awareness In The Training Of Phonetic Transcription With Slp Students, Jennifer Kay Binkley

Dissertations and Theses

A dissertation study was developed and completed to further explore the relationship between phonological awareness (PA) and phonetic transcription skills in undergraduate speech-language pathology students. A review of the literature provides gaps in knowledge which the proposal seeks to address. Based upon this literature review, the researcher compared PA skills of undergraduate students of various majors, to determine if there was a change in PA by taking a traditional phonetics course, and to explore phonetic transcription outcomes as the result of direct PA intervention with undergraduate SLP students. Quantitative analysis was used to answer three research questions, which were organized …

Ancillary Data For Refining Computer Adaptive Algorithms For The Assessment Of Anomia, Emily Kathryn Tudorache

Dissertations and Theses

Computer adaptive testing formats, based in item response theory (IRT), are becoming an increasingly popular approach to testing in healthcare because they offer numerous psychometric and practical advantages to assessment when compared to static tests that rely on classical test theory. Fergadiotis and colleagues (2015) have developed computer adaptive versions of the Philadelphia Naming Test (PNT) short-forms, which have demonstrated acceptable precision and standard error of measurement when compared to the static short-forms and original full-length assessment. This study sought to use synthetic data simulations using the catIrt R package (Nydik, 2014) to investigate possible advantages of the use of …

Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts

Dissertations and Theses

Speech-language pathologists provide assessment and intervention for communication, cognition, and swallowing disorders for individuals across the lifespan in educational, medical, and private practice settings. The demographics of professionals in the field do not reflect those of the general public in regard to race and ethnicity, gender, socioeconomic status, LGBTQ+, and disability. Lack of representation of minorities limits research, policy, and services designed to serve diverse populations. Although initiatives have sought to address lack of diversity of speech-language pathologists, limited research on the graduate training experience for minority students is available. Since a master's degree is required to become a speech-language …

Implicit Learning Of Children With And Without Developmental Language Disorder Across Auditory And Visual Categories, Wanchi Yu

Dissertations and Theses

The current study examined implicit sound- and visual-meaning-mappings of children with and without Developmental Language Disorder (DLD).

One child with DLD and 29 children with typical language development (TLD) were included in the study, based on results from a hearing screening and standardized assessments of cognitive and expressive language skills. Participants completed two computer-based experiments, which were designed to investigate: 1) sound discrimination (pitch and duration), implicit mapping of sound stimuli to objects; 2) visual discrimination, implicit mapping of visual stimuli to objects.

The current study showed that children with TLD who implicitly learned pitch categories showed better mapping of …

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 …

Investigation Of Speech Samples From Typically Developing Preschool Age Children: A Comparison Of Single Words And Imitated Sentences Elicited With The Paba-E, Matthew William Olsen

Dissertations and Theses

Assessment of speech sound production in young children provides the basis for diagnosis and treatment of speech sound disorders. Standardized single-word articulation tests are typically used for identification of speech sound errors because they can provide an efficient means of obtaining a speech sample for analysis and comparison to same-age peers. A major criticism of single-word articulation tests is that they may not accurately reflect speech sound production abilities in conversation. Comparison of performance in single-word and conversational contexts has produced conflicting results in the available research.

The purpose of the present study was to compare speech samples obtained using …

High Frequency Pure Tone Audiometry And High Frequency Distortion Product Otoacoustic Emissions: A Correlational Analysis, Kimberly J. Lavoie

Dissertations and Theses

Previous studies show that pure tone thresholds are strongly correlated with distortion product otoacoustic emission amplitudes when evaluating the frequency range from 1 to 8 kHz (Avan & Bonfils, 1993). Little is known about correlations between these two measures at higher frequencies from 9-16 kHz. This study compared pure tone thresholds and distortion product otoacoustic emissions (DPOAEs) in this high frequency range for 29 normal hearing subjects ages 18-30. Pure tone thresholds were obtained at 250-16 kHz and distortion product otoacoustic emissions (DPOAE) 2,211-17,675 were measured in the same ears. DPOAE amplitudes were measured using a constant F1/F2 ratio of …

Effects Of Three Training Components In An Aac Intervention For An Adult With Severe Broca’S Aphasia, Bradley Josef Hendershott

Dissertations and Theses

Individuals with severe nonfluent aphasia may lose functional verbal communication. With the loss of fluent speech, one may also lose the capacity to share in the casual conversation that enriches our lives. A rehabilitative course that seeks to stimulate restoration of verbal abilities can be lengthy with uncertain outcomes. Fortunately, Augmentative and Alternative Communication (AAC) interventions have shown promise in treating aphasia by providing non-verbal means of communicating. Communication aids designed around specific topics and comprised of words and pictures have been used by persons with aphasia to participate in conversations. Such aids have shown promise in facilitating successful conversation …

The Effect Of Using Averaged Versus Custom Real-Ear To Coupler Difference Values In The Desired Sensation Level Approach To Prescribing Hearing Instrument Gain, John Aaron Coverstone

Dissertations and Theses

Because there are many variables and much missing information when fitting young children with hearing instruments, it is necessary to rely on prescriptive procedures such as the Desired Sensation Level (DSL) Method to create target 2cc gain values for ordering and fitting hearing instruments. Inherent in creating 2cc targets is a conversion process known as a real-ear to coupler difference (RECD) measurement. The DSL algorithms make allowances for averaged data to be used in lieu of this measurement.

The purpose of this study is to evaluate the validity of using averaged real-ear to coupler difference values included in the DSL …

Dissertations and Theses

Earobics Pro PLUS Step I (Earobics I) is a software program designed to increase the auditory processing and phonological awareness skills of children when used in conjunction with traditional intervention. Phonological awareness is the ability to manipulate the sounds of a language and has been shown in previous studies to have a strong relationship with reading ability. Phonological awareness can be taught, and studies have been conducted in an effort to determine effective methods for teaching phonological awareness. No studies have been published on Earobics I to this date.

In this study, the effectiveness of Earobics I was analyzed with …

The Effectiveness Of Hypermedia Training Vs. Traditional Classroom Instruction In Stuttering, Micheal Dean Baran

Dissertations and Theses

A study by Henri (1994) showed that fluency is one of two areas where speech-language pathology clinicians feel least prepared and Sommers and Caruso (1995) advocated improved training in fluency. The use of computer technology to train students in the field of stuttering has been proven effective in previous studies (Strang, Meyers & Hall, 1989; Tetnowski & Martin, 1996).

The purpose of this study was to further develop a hypermedia training module for stuttering identification and to determine whether this hypermedia training module was as effective as traditional classroom teaching methods.

Subjects in this study were undergraduate students in speech …

Speech Production Patterns Following Management Of Velopharyngeal Inadequacy, Debra Lynn Childs

Dissertations and Theses

This descriptive study investigated the pattern of speech sound production before and after surgical management of velopharyngeal inadequacy in two subjects. The research questions asked were: (a) What type of speech patterns do subjects referred for surgical management of velopharyngeal incompetence demonstrate presurgically? (b) What changes in the speech patterns of the subjects are observed in the immediate month following surgery for velopharyngeal incompetence? (c) Do these changes settle into a stabilized pattern of speech production by 4 months postsurgery?

The subjects' speech productions were audio recorded for analysis using the Broen CVC Probe to obtain imitated single word elicitations …

Concurrent Validity Of Mental Ability Screening Tools : A Comparison Of Normal Students’ Performance On The Kaufman Brief Intelligence Test And The Shipley Institute Of Living Scale-Revised, D. Melanie Peters

Dissertations and Theses

This study compared the Kaufman Brief Intelligence Test (K-BIT), a verbal and nonverbal mental ability screening tool, to the Shipley Institute Living Scale (SILS), a nonverbal screening tool of mental ability, as part of a larger, ongoing study which is examining the effects of orofacial clefts on early career maturity. In terms of general intellectual ability, the K-BIT and the SILS provide descriptive categories, percentile ranks, raw scores, standard error of measurement, standard scores, standardization and norms, subtest scores, and total scores. The K-BIT provides normative curve equivalents and stanines, which the SILS does not. The SILS provides abstract and …

The Effect Of Diastema Closure On The Remediation Of Lateral /S/: A Case Study, Reta Price

Dissertations and Theses

An important morphological-marker and one of the most frequently occurring speech sounds in English, the /s/ phoneme is also one of the sounds most often in need of remediation. Often, air emission during /s/ production, a particularly stubborn, often residual production error, is not remediated through traditional treatment methods, and yet the negative effect /s/ distortions have on listeners has been well-documented.

The subject of this investigation was a forty-eightyear-old male who received treatment for a lateralized /s/ during grade-school. It was hypothesized that his exerting high anterior pressure to prevent air from escaping from a diastema between his two …

Career Orientation Levels In Adolescents : A Comparison Of Cleft And Noncleft Subgroups, Tara Darice Gaddis

Dissertations and Theses

The current research studied career orientation levels during adolescence utilizing previously collected cross-sectional data on 80 subjects. The subjects had participated in a study focusing on the ways in which clefting, gender, self-concept, mental ability, and socioeconomic status impact career development. Preliminary analysis of the data found that self-concept, mental ability, self-ratings of facial appearance, and desired level of future educational status were the factors most predictive of level of career development. In the initial analysis of the data, subjects, cleft and noncleft, who demonstrated high self-esteem, high mental ability, reported a more advanced level of desired higher education, and …

A Longitudinal Study Of The Career Maturity Patterns Of Individuals With Clefts, Joyce Johnson Anderson

Dissertations and Theses

Sixteen subjects (6 males, 10 females) during adolescence and in young adulthood completed (a) a biographical questionnaire which provided educational and occupational information, (b) the Career Development Inventory, (c) the Tennessee Self-Concept Scale, (d) the Shipley Institute of Living Scale, and (e) self-ratings of speech and facial appearance acceptability to provide information concerning career maturity, mental …

Examination Of Benefits Of Binaural Auditory Stimulation For Children With A Cochlear Implant And A Hearing Aid In The Contralateral Ear, Evonne Nicol Altesleben

Dissertations and Theses

Congenital or acquired hearing impairments put children at risk of delayed language development. Today the cochlear implant (Cl) is a viable amplification option for some children with profound hearing losses. Audiologists often recommend that children with hearing impairments be fitted with binaural hearing aids in the hope that maximum stimulation will occur and that auditory deprivation will be lessened. An area lacking investigation is whether binaural stimulation will be beneficial to the cochlear implant recipient.Controversy also exists regarding the use of a hearing aid in the non-implanted ear.

The focus of this study was to compare binaural auditory stimulation benefits …

A Comparison Of Listener And Speaker Perception Of Stuttering Events, Anne Jocelyn Schagen

Dissertations and Theses

Stuttering identification, measurement, research, and treatment have for many years had their basis in listener judgment of stuttering, but the covert aspects of stuttering are not behaviorally observable, and inter-rater reliability has repeatedly been shown to be low. Perkins (1990) has emphasized the importance of consulting the speaker for the most reliable perspective on stuttering identification. The question raised in this study is whether there is a significant correlation between stuttering identification based upon internal perception by a speaker who stutters, and identification based upon external perception of listeners, with points of inter-rater disagreement removed. Six adult males, aged 18 …

First Language And Gesture Acquisition In Children With Cerebral Palsy, Ann Christine Friel

Dissertations and Theses

Many children with Cerebral Palsy (CP) will receive speech and language intervention throughout their lives. However, there is a lack of descriptive data for language and gesture development of children with CP. When assessing the skills of children with CP, standardized tests and clinical observations have several inherent faults due to time constraints, normative data, and physical constraints. An alternative method used to gather data in the area of language and gesture development is parent questionnaire. The MacArthur Communicative Development Inventory: Words & Gestures was chosen for this study because it has been shown to be an efficient, valid, and …

The Effectiveness Of Planned Transitions Therapy In The Treatment Of Three Children With Developmental Verbal Dyspraxia, Emily M. Campbell

Dissertations and Theses

The intent of this investigation was to note whether use of Planned Transitions Therapy (PTT) would help to improve the intelligibility of 3 children with developmental verbal dyspraxia (DVD). PTT is an approach that emphasizes the sequencing of lingual movements from one place of articulation to the next for the production of speech. Rather than focusing on the production of sounds, exercises with PTT focus on transitions between sounds.

Three male subjects presenting characteristics of DVD received 30-minute treatment sessions with a traditional intervention approach for 6 weeks. Each subject also received periods of intervention with PTT. Subject A received …

A Comparison Of Speech Onset Latencies Between Persons Who Stutter And Persons Who Do Not Stutter Across Varied Phonological Priming Conditions, Brian Joseff Riffel

Dissertations and Theses

A recent theory of stuttering, the "Covert Repair Hypothesis of Disfluencies" (Kolk & Postma, in press; Postma & Kolk, 1992, 1993), accounts for the difference between persons who stutter (PWS) and persons who do not stutter (PWNS) by concluding that PWS are slower than PWNS in their phonological encoding abilities. This belief is supported through experimental studies by Bosshardt (1990) and Postma et al (1990), both of which found PWS to be slower than PWNS in silent reading tasks. In addition, Wijnen and Boers (1994) found that PWS demonstrate longer speech onset latencies than PWNS at baseline, but then approximate …

Effects Of Orofacial Clefts On Early Career Maturity, Jeanniekay Mccall

Dissertations and Theses

The purpose of this study was to investigate career maturity in 14- and 17- year-old male and female adolescents with cleft lip and palate. Career maturity is defined as the repertoire of behaviors pertinent to identifying, choosing, planning, and executing career goals available to a specific individual as compared with those possessed by a peer group. Clefting is a congenital anomaly that occurs in approximately 1 in every 600 newborns and can result in facial scarring and speech deviations that may last throughout life, and may result in complications such as withdrawal, inhibition, lower self-esteem, and increasing self-doubt regarding interpersonal …

Real Ear To Coupler Differences In Children And The Effects Of Hearing And Microphone Location, Cindy Richardson

Dissertations and Theses

The early identification of hearing loss and selection of appropriate amplification are the most important goals for children with hearing impairment. Selection of appropriate amplification for a pediatric population involves maximizing the hearing impaired child's residual hearing, for development of speech and language. In addition, it is important to consider the acoustic differences between the 2 cc coupler versus the real ear.

During the hearing aid selection process, it is customary to predict how a hearing aid will respond in the real ear, based upon a given 2 cc coupler response. Killion and Monser (1980) developed a formula for converting …

Dissertations and Theses

The purpose of this study was to examine the relationship between receptive language skills and nonverbal cognitive skills in preschool children with cerebral palsy and a mild to severe motor speech impairment. In addition, the relationship between the severity of motor impairment and receptive communication and nonverbal cognitive skills was also examined. Fifteen subjects, 10 males and 5 females, were included in this study. The subjects are part of a larger longitudinal study being completed within Portland State University's Speech and Hearing Sciences Program. All of the subjects participated in two in-home assessment sessions, which were approximately 2 hours long. …

Gross Estimation: A Study Of The Clinical Validity For Measuring Intelligibility, Heather Gail Clarke

Dissertations and Theses

Intelligibility is the most fundamental factor for successful speech communication. Measurements of speech intelligibility carry important clinical consequences that relate to description of severity, need for intervention, intervention goals, service delivery options, and treatment efficacy. It is important, therefore, that speech-language pathologists use an approach that reflects an accurate and valid measure of intelligibility. The purpose of this study was to investigate the relationship between the two seemingly most common procedures used by practicing speech-language pathologists for measuring speech intelligibility: the gross estimation of intelligibility procedure, and the orthographic transcription procedure. Twelve 100-word connected speech samples were analyzed by 4 …

A Study Of The Level Of Knowledge Of Adult Foster Care Home Providers In Multnomah County In The State Of Oregon About Hearing Loss, Hearing Aids And Communication Strategies, Marsha Peters Johnson

Dissertations and Theses

The level of knowledge about hearing aid use, function, and maintenance of caregivers of the elderly persons who are hearing impaired and residing in adult foster care homes in Multnomah County in the state of Oregon was assessed via a 1 7 question survey. Twenty subjects participated in the study. Subjects' responses demonstrated poor knowledge about this subject and indicated that residents' needs are unmet. The results clearly demonstrate the subjects' limited knowledge of the operation of hearing aids, poor grasp of the basic troubleshooting methods for repair, and inaccurate perceptions of hearing aid adjustment. Access to professional audiologic care …

Comparison Of Intelligibility Estimation And Orthographic Transcription Methods By Preprofessional Speech-Language Pathologists, Kristi M. Mowe

Dissertations and Theses

When the fundamental means of communications is speech, the main component for successful communication is intelligibility. The speech of children with disordered phonologies is often unintelligible; therefore, accurate and reliable methods of measuring intelligibility are essential when determining eligibility, and in selecting and providing appropriate treatment.

The purpose of this study was to investigate the relationship between the percentage estimation method and the orthographic transcription method when measuring speech intelligibility by preprofessional listeners. For this study, the standard measurement of intelligibility was defined as the percentage of words understood in a continuous speech sample derived from orthographic transcription of the …

Ethnography Of Communication As On Organizational Communication Assessment Tool: A Test Of The Method, Francisca Inez Trujillo-Dalbey

Dissertations and Theses

Professional organizational consultants and researchers performing organizational communication assessments with non-profit boards of directors have few tools available to them and many of these tools under emphasize the centrality of communication and overlook the power-asdomination (Mumby, 1994) issues present in organizations. This study tested the ethnography of communication (Hymes, 1972) as an organizational communication assessment tool with a board of directors of a non-profit organization in Oregon and examined the results by employing Mumby's (1994) construct, thereby conducting a critical ethnography of communication.

This study offers important insights into boards of directors of nonprofit organizations and has important implications for …
