Perceptions Of Stuttering Intervention Services Received At Portland State, Franklin Wayne Bender

Dissertations and Theses

As consumers become more knowledgeable and more demanding of accountability, health care workers, including speech-language pathologists, are being required to justify the effectiveness of their work by documenting the results of their treatment programs. There are different ways to measure treatment outcomes. Outcomes may be measured qualitatively and/or quantitatively. Qualitative or subjective outcomes are difficult to define and measure and few studies of this type have been reported in the literature. Because few studies have been reported in the literature regarding client satisfaction, this area was investigated in this research project. The focus of this project was to ascertain whether …

A Survey Of Swallowing Symptoms Associated With The Premenstrual Cycle, Jill Gigi Calcagno

Dissertations and Theses

Premenstrual Syndrome (PMS) has been associated with a vast number of physical, emotional, social, and behavioral symptomatology. Laryngeal disturbances invoked by hormonal imbalance may affect swallowing as a component of PMS. Previous studies regarding swallowing ability during the premenstrual cycle were nonexistent.

This study examined the relationship between PMS and swallowing disorders. One hundred thirty-seven females completed a written survey that elicited information regarding biographical data, presence and severity of cyclically recurring symptoms associated with PMS, and perceived presence and severity of dysphagia during premenstruum.

Spearman Rank (Rho) correlation coefficients were computed to determine the extent of the relationship between …

Conflict Is Optional, Difference Is Not : Toward A Difference-Based Approach To Interpersonal Communication, James Arthur Gieseking Jr

Dissertations and Theses

An examination of the discussion of conflict in general, interpersonal and small group communication texts indicates that the conceptualization of conflict theory in the U.S. is increasingly dependent upon three theoretical pillars: the qualities of ubiquity, utility and necessity. A critical, deconstructive analysis of these operational characteristics in relation to the actual human experience of conflict reveals that they are more appropriately associated with the essential condition of difference, rather than conflict, and the concepts of conflict and difference are generally conflated in U.S. communication texts. The synergistic interaction of a variety of specific cultural constructs can be seen as …

The Affects Of Vocal Fatigue On Fundamental Frequency And Frequency Range In Actresses As Opposed To Non-Actresses, Ruth Ann Jenkins

Dissertations and Theses

Differences may exist between the voice qualities of those who professionally use and train their voices and those who do not. The examination of fundamental frequency and frequency range m actresses and non-actresses is integral to determining voice quality differences in these populations. These differences, whether the result of frequent use or training of the voice, may exist relative to fatiguing conditions such as may be experienced by actresses in the course of their work. Fatigue has been shown to produce greater effects in normals than in performers, particularly in singers (Gelfer, Andrews, and Schmidt, 1991). Little research has been …

Efficacy Of A Cycling Approach For The Treatment Of Developmental Verbal Dyspraxic Preschoolers, Janet Rose Lambert

Dissertations and Theses

Two preschool males who presented with the characteristics of developmental verbal dyspraxia were enrolled in a phonological cycles intervention approach. Initially, each child's deviant phonological processes were analyzed by the CAPD and target patterns and words selected for remediation. A continuous speech sample was obtained and analyzed to measure intelligibility by percentage and rating on a seven point scale. A time-space probe was developed based on targeted and non-targeted phonemes and administered prior to the first intervention session. Using the selected targeted patterns and words, an individualized remediation plan was developed, and the phonological process cycling approach used. Each subject …

Effects Of Task Difficulty On Naming Performance Of Aphasic Subjects, Susan Kay Kucera

Dissertations and Theses

This investigation examined the effects of task difficulty on aphasic individuals' naming performance. Subjects were presented lists of easy-to-name and difficult-to-name items. In the high success condition, difficult lists were interspersed among a larger number of easy lists. In the low success condition, easy lists were interspersed among a larger number of difficult lists. Percentages of correct responses for administration of each list were calculated for each subject. Group means for each list were derived by averaging the individual scores. Group means in the high success and the low success conditions were compared with baseline measures to determine experimental effects. …

A Comparison Of Grammatical Morpheme Usage By Four Year Olds With Normal, Impaired, And Late Developing Language, Sally Alforde

Dissertations and Theses

The purpose of this study was to determine whether language-disordered four-year-old children and those with a history of language delay but currently normal functioning would have acquired a significantly lower percentage of 13 grammatical morphemes than children of the same age with normal language skills. Research has shown that there is a consistency of order in which these morphemes are acquired in children with normal language ability. Studies have also shown that while language disordered children acquire these grammatical morphemes in a similar order, the process is slowed down. Language disordered children have difficulty with grammatical morpheme development. Not found …

The Percentage Consonants Correct And Intelligibility Of Normal, Language Delayed, And History Of Language Delayed Children, Randi Jartun

Dissertations and Theses

Highly unintelligible children may mistakenly be assumed to have difficulty only with the misarticulation of consonants. Expressive language concerns may be ignored while the primary focus of intervention becomes the correction of misarticulated speech. Questions have arisen regarding the possibility of both speech and expressive language difficulties contributing to unintelligibility. Shriberg and Kwiatkowski (1982) developed an ordinal means of rating severity of involvement. One of the constructs of the severity scale was intelligibility. The metric percentage consonants correct (PCC) was developed to identify severity of involvement of disorders of phonology.

A Study Of The Narrative Skills In Kindergarten Children With Normal, Impaired, And Late Developing Language Development, Lisa L. Mcfarland

Dissertations and Theses

Children's narrative language plays a critical role in guiding the transition between oral language and literacy (Roth & Spekman, 1989; Westby, 1989). Narrative comprehension and production by normally achieving and language delayed school-aged children have been studied. Many of these studies have involved story retellings. Few have studied how spontaneously produced narratives are organized especially by young children.

Word Retrieval Behaviors Of Aphasic Adults In Conversational Speech : A Preliminary Study, Priscilla Jane Blake

Dissertations and Theses

Word retrieval difficulties are experienced by almost all aphasic adults. Consequently, these problems receive a substantial amount of attention in aphasia treatment. Because of the methodological difficulties, few studies have examined WRBs in conversational speech, focusing instead on confrontational naming tasks in which the client is asked to retrieve a specific word. These studies have left unanswered questions about the WRB processes.

The purposes of this study were to: (1) develop profiles of WRB for moderately impaired aphasic adult clients and examine these profiles for evidence that reflects the level of breakdown in the word retrieval process, and (2) determine …

A Study Of The Association Among The Diagnosis Of Speech-Language Impairments And The Diagnoses Of Learning Disabilities And/Or Attention Deficit Hyperactivity Disorder, Pamela E. Cogswell

Dissertations and Theses

The purpose of this study was to determine if an association exists among the diagnosis of speech-language impairments (SLI) and the diagnoses of learning disabilities (LD) and/or attention deficit hyperactivity disorder (ADHD) in a school-aged population of children referred to a Learning Disorders Clinic (LDC) because of academic underachievement and/or behavior problems. The two research questions asked in this study are: (a) What percentage of students diagnosed with SLI have a concomitant diagnosis of LD and/or ADHD? and (b) Is there an association among the diagnosis of SLI and the diagnoses of LD and/or ADHD?

A sample of 94 subjects …

The Effect Of Otitis Media On Articulation In Expressive Language-Delayed Children, Marla Lohr-Flanders

Dissertations and Theses

Researchers have long been concerned with the effects of otitis media on speech and language acquisition because of the high correlation of a mild to moderate hearing loss during the time period that fluid (effusion) may be in the middle ear. Middle-ear effusion would prevent many of the auditory messages from accurately reaching the nervous system (Zinkus, 1986). Deprived of the ability to discern the subtle acoustic differences that provide information for phonetic contrasts, a child's speech acquisition may differ from children who do not experience such losses.

The present study examined the relationship between an early history of otitis …

Effects Of Encouraging, Discouraging, And Neutral Instructions On Naming By Aphasic Subjects, Denise Marie Nelson

Dissertations and Theses

The purpose of this investigation was to examine the influence of three instructional conditions (encouraging, discouraging, and neutral) on eighteen aphasic adults' performance on a naming task. Each subject listened to each audiotaped instructional condition followed by a 20 picture naming task presented with a slide projector for a total of three tasks and 60 pictures. Subjects' mean scores were combined and averaged to derive a grand mean score for each instructional condition. A repeated measures analysis of variance was applied to determine if the differences were significant at the .01 level. No significant differences were found.

Indirect Intervention For Preschool Stutterers, Prudence Ann Bowers

Dissertations and Theses

This study investigated the advisability of utilizing parents to provide treatment for their dysfluent preschoolers. It involved the development, implementation and evaluation of a specific treatment program involving indirect language stimulation techniques. The primary question asked was whether or not parents can be successful in significantly reducing or eliminating dysfluent speech in their children. The secondary question was whether or not parents can be trained successfully to provide treatment.

A Comparison Of The Vocabulary Needs Of Speaking And Nonspeaking Twins, Dana Lynette Hamburg

Dissertations and Theses

Children with severe physical disabilities often do not have the capabilities for oral communication. Therefore, the vocabulary needs of nonspeaking children has been a subject of research in the area of augmentative communication for a number of years. The idea of allowing children with disabilities the opportunity for expression and communication is one not easily ignored. Obtaining vocabulary items, however, that are useful to nonspeaking disabled children that also meet normal language acquisition standards has been a concern. This study specifically addresses this concern by looking into the vocabulary issues of twins. The purpose of this research project is to …

The Correlation Between Correct Verbal And Nonverbal Responses On An Intelligence Test And Expressive Language Test Score, Jeanie P. Wagener

Dissertations and Theses

The purpose of this study was to examine the relationship between verbal and nonverbal indices of intelligence from an infant development scale given at approximately two years of age with scores on an expressive language test administered to the same children two years later. The questions this study sought to answer were: (1) is there a difference between the number of verbal and nonverbal items passed at 18-34 months by a group of normal children and a group of late talkers, (2) is there a significant relationship between correct verbal and nonverbal responses on an infant development test and scores …

Output Of Compression Hearing Aids With Transient And Continuous Input Stimuli, Carol Ann Gregory

Dissertations and Theses

The purpose of this study was to determine whether the compression circuit of a hearing aid could be activated by a high frequency biasing tone such that its output for a transient stimulus could be made to approximate that of a continuous tone alone. Sufficient compression activation by a transient stimulus would mean that this type of hearing aid could be used in obtaining aided ABR measurements, since transient stimuli are commonly used for this procedure. Four hearing aids were used, and transient or continuous stimuli were introduced either alone or in combination with an 8 or 10 kHz biasing …

A Retrospective Study Of The Clinical Evaluation Of Language Functions Elementary Screening Test (Celf-S), Tamara Lynn Caldwell

Dissertations and Theses

One of the more widely-used methods for pinpointing children in need of more in-depth language evaluation is screening. One language screening instrument designed to accomplish this in an effective and efficient way was the Clinical Evaluation of Language Functions Elementary Screening Test (CELF-S) (Semel & Wiig, 1980).

The purpose of this study was to determine the effectiveness of the CELF-S in identifying those children in a second grade setting, who were in need of more thorough evaluation. This study sought to answer the following questions: 1) What is the percentage of false negatives produced by the CELF-S?, and 2) What …

The Value Of The Spi In Forecasting Chronic Stuttering, Dena Diane Stork

Dissertations and Theses

Speech-language pathologists are in need of useful assessment instruments which differentiate early stuttering behaviors and will enable them to identify preschool children who need immediate intervention for stuttering. Furthermore, useful assessment tools are needed especially due to the variability across studies of normal disfluency and lack of reliability information on more formal measures of differential evaluation of normal disfluency and incipient stuttering.

Comparison Of The Modal Frequency Levels Of Nonsmoking And Cigarette Smoking White Females Between The Ages Of Forty And Fifty Years, Janis Mae Kaufman

Dissertations and Theses

Acoustical analyses have been utilized to ascertain the functional status of the laryngeal mechanism for clinical management of communication disorders. In particular, the modal frequency level (MFL), defined as the fundamental frequency most often used by an individual in the act of spontaneous speech, is one measurement used to determine if a person's pitch level is adequate. Two other pitch measurements used in the voice assessment are the maximum frequency range (MFR) and the optimum pitch level (OPL). Information is needed to provide guidelines for pitch levels as part of the voice evaluation for adult females of different ages. It …

High Frequency Acoustic Reflexes In Cochlea-Impaired And Normal Ears, Karen Elizabeth Jones

Dissertations and Theses

The acoustic reflex refers to the contraction of a middle ear muscle in response to sound. The contraction causes a stiffening of the middle ear system and, consequently, the flow of acoustic energy to the cochlea is impeded. By measuring the change in admittance in the auditory system during sound stimulation it is possible to indirectly monitor the middle ear muscle contractions. Such measurements provide useful information regarding the integrity of the auditory system and the location of the auditory pathology.

In subjects with normal hearing sensitivity, the acoustic reflex is typically elicited at a sensation level of between 85 …

Intelligibility Of Spondees Via Bone Conduction At Elevated Presentation Levels, Pamela S. Ritchie

Dissertations and Theses

Speech reception threshold testing by bone conduction is very useful in diagnostic audiometry. However, there are little data regarding the CID W-1 spondee word lists used with the Radioear B-71 and B-72 and Pracitronic KH 70 bone conduction vibrators at higher presentation levels for testing hearing impaired clients. Data are needed in order that results of speech reception thresholds using the CID W-1 word lists via these three bone conduction vibrators at higher intensity levels can be used confidently in the clinic. More data are available for speech reception thresholds using the CID W-1 word lists via earphones.

This study …

The Assessment Of Phonological Processes : A Comparison Of Connected-Speech Samples And Single-Word Production Tests, Susan A. Pinkerton

Dissertations and Theses

The purpose of this study was to determine if single-word elicitation procedures used in the assessment of phonological processes would have highly similar results to those obtained through connected speech. Connected speech sampling provides a medium for natural production with coarticulatory influence, but can be time-consuming and impractical for clinicians maintaining heavy caseloads or working with highly unintelligible children. Elicitation through single words requires less time than a connected-speech sample and may be more effective with highly unintelligible children because the context is known, but it lacks the influence of surrounding words. Given the inherent differences between these two methods …

A Comparison Of Two Methods For Measuring The Attenuation Provided By Insert-Type Hearing Protection Devices, Brenda Barrett Kabat

Dissertations and Theses

The need for hearing protection in industry has evolved from the growing awareness of the detrimental effects of noise on hearing and recent legislation enacted to protect the hearing of noise-exposed employees through the use of hearing conservation programs. In lieu of expensive or impractical engineering and administrative controls, personal hearing protection devices (HPDs) are considered to be the most practical and effective means of protecting employees from the damaging effects of noise in industry today.

Reading Comprehension Of Literal, Translational, And High Inference Level Questions In Aphasic And Right Hemisphere Damaged Adults, Ute Kongsbak

Dissertations and Theses

The purpose of this study was to examine and compare inferential abilities on a reading comprehension task in two groups of adults who had suffered cerebrovascular accidents (CVA). Sixteen subjects with a CVA to the right hemisphere of the brain were compared to an equal number of left hemisphere damaged subjects. Subjects were selected after they had demonstrated an adequate level of functioning on the Short Porch Index of Communicative Ability (SPICA), a test which measures communicative efficiency, to perform the tasks required in this study. All subjects were administered the revised version of the Nelson Reading Skills Test (NRST). …

The Use Of Phonological Process Assessment For Differentiating Developmental Apraxia Of Speech From Functional Articulation Disorders, Kathryn Dearmond

Dissertations and Theses

Focus has turned from emphasis on phonetic sound errors to phonologic rule systems in the study of articulation disorders. The current theory proposes that the phonological disorders which children experience are controlled by higher levels in the brain than those that control the motor functioning of the brain. The purpose of the present study was to compare the use of phonological processes by a group of school-age children with moderate to severe multiple articulation disorders (MAD) with developmental apraxia of speech (DAS) to the phonological processes used by those without developmental apraxia of speech. For the purposes of this study, …

Audiological In-Service Regarding Hearing Impairment And Its Impact On Communication In The Geriatric Population, Marie Barlow Lassell

Dissertations and Theses

At least two studies have been found conducted in the area of audiological in-services and their impact on the people to whom they were presented. In 1981, Dancer and Keiser studied the effects of empathy training on geriatric-care nurses and in 1985, Dampier, Dancer, and Keiser studied changing attitudes of college students toward older persons with hearing loss. Both of the studies investigated the effect of in-service training on empathy, rather than using the traditional academicallyoriented in-service program approach. Both studies found statistical results indicating a significant positive change in the subjects' feelings toward hearing impaired geriatrics. Additionally, Dancer et …

Speechreading Ability In Elementary School-Age Children With And Without Functional Articulation Disorders, Barbara L. Habermann

Dissertations and Theses

The purpose of this study was to compare the speechreading abilities of elementary school-age children with mild to severe articulation disorders with those of children with normal articulation. Speechreading ability, as determined by a speechreading test, indicates how well a person recognizes the visual cues of speech. Speech sounds that have similar visual characteristics have been defined as visemes by Jackson in 1988 and can be categorized into distinct groups based on their place of articulation. A relationship between recognition of these visemes and correct articulation was first proposed by Woodward and Barber in 1960. Dodd, in 1983, noted that …

The Use Of The California Consonant Test And The Northwestern University Auditory Test No. 6 In Hearing Aid Evaluations For Individuals With Precipitous Losses Above 1 Khz, Bradley James Allard

Dissertations and Theses

These two joint-studies used recorded versions of the Northwestern University Auditory Test Number 6 (NU-6) and the California Consonant Test (CCT) in the hearing aid evaluations (HAEs) of 12 male and one female subjects, aged 41 to 87 years. They exhibited precipitous high frequency losses beyond 1 kHz in at least one ear. All subjects were evaluated without amplification and while monaurally aided with two conventional high pass hearing aids. Ten of the subjects were evaluated in multi-talker noise and 11 were tested in quiet. Since the CCT was more heavily weighted than the NU-6 with target phonemes sensitive to …

Written Narratives Of Language Disordered And Normal Adolescents On Two Tasks, Antigone Howick Brown

Dissertations and Theses

The purpose of this study was to describe written narratives of language disordered adolescents by comparing their written narratives via story grammar analysis with those of normal adolescents. The written narratives were obtained by administering two tasks as required assignments within the English or communications classes of the two groups. Task A was to write about a personal experience and Task B was about an imaginary experience. This study used Merritt and Liles' adaptations (1987) of Stein and Glenn's procedures (1979) for story grammar analysis to describe the content of the narratives.
