Speechreading Ability In Elementary School-Age Children With And Without Functional Articulation Disorders, Barbara L. Habermann Jan 1990

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 Phonological Process Assessment For Differentiating Developmental Apraxia Of Speech From Functional Articulation Disorders, Kathryn Dearmond Jan 1990

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 Jan 1990

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 …


Pragmatic Conversational Skills Of Children Identified As Emotionally Disturbed, Deidre Winder Jan 1990

Pragmatic Conversational Skills Of Children Identified As Emotionally Disturbed, Deidre Winder

Dissertations and Theses

Communication refers to the conveyance of intended messages so that the listeners' attitudes, beliefs, or behaviors are changed. Communication through a language system may be thought of as the integration of the three components of content (semantics), form (syntax), and use (language in context or pragmatics). The corning together of content, form, and use in signs, words, phrases, and discourse is the essence of language development. The synergism of content/form/use makes up language competence, or knowledge. When children speak and understand a message, they have a plan that is knowledge of language and they use that plan for the behavior …


Hourly Fluctuation Of Middle Ear Pressure As A Function Of Age In School-Age Children, Susan Hogue Henry Oct 1989

Hourly Fluctuation Of Middle Ear Pressure As A Function Of Age In School-Age Children, Susan Hogue Henry

Dissertations and Theses

Tympanometry is a useful means of evaluating the status of the middle ear. For the pediatric population, tympanometry is particularly valuable for determining the presence of middle ear effusion. The test has been incorporated in many school hearing conservation programs because of its ease of administration, objectivity, and diagnostic value.

In a study by deJonge and Cummings (1985), the hourly fluctuation of middle ear pressure was reported in a group of kindergarten-age children. The variability of middle ear pressure for that group of children averaged 150 daPa. In the present study, a maturational effect of this hourly fluctuation was observed …


Communication And Socialization Skills Of Three Year Olds With A History Of Language Delay, Pamela Susan Dahm Jun 1989

Communication And Socialization Skills Of Three Year Olds With A History Of Language Delay, Pamela Susan Dahm

Dissertations and Theses

The purpose of this study was to compare receptive language, expressive language, and socialization skills of preschool children who have a history of expressive language delay (ELD) with age mates who have a history of normal language development.


A Comparison Of The Maladaptive Behaviors Of Normal, Language Delayed, And Late Talking Toddlers, Denise Elaine James Jun 1989

A Comparison Of The Maladaptive Behaviors Of Normal, Language Delayed, And Late Talking Toddlers, Denise Elaine James

Dissertations and Theses

People use language to communicate their needs and intentions, to express emotions, and to form relationships. It seems likely that a disruption in children's language development would have a negative impact on their social development. There is extensive research that shows that school age children with delayed language are "at risk" for increased maladaptive behaviors (Cantwell and Baker, 1977). Whether this is also true for children in the earliest stages of language development is not yet known.

The questions this study sought to answer were: 1) Is there a significant difference in the severity and frequency of maladaptive behaviors seen …


Maternal Linguistic Input To Normal And Expressive Language Delayed Toddlers, Terril Joy Elwood Jun 1989

Maternal Linguistic Input To Normal And Expressive Language Delayed Toddlers, Terril Joy Elwood

Dissertations and Theses

Research suggests that the linguistic environment of the expressive language delayed child is different from that of his peers. Does this difference actually exist and if so, what are its characteristics? The purpose of this study was to describe the linguistic characteristics of mothers' input to children with normal language acquisition and those of mothers of expressively delayed toddlers; and to identify any differences between these groups. Though considerable research exists in this area, few studies have dealt specifically with large groups of expressively delayed toddlers.


A Comparative Analysis Of The Expressive Acquisition Of Locative And Directional Prepositions Between Severely-To-Profoundly Hearing Impaired Children Utilizing Total Communication And The Oral/Aural Approach, Cathleen Pew Edwards May 1989

A Comparative Analysis Of The Expressive Acquisition Of Locative And Directional Prepositions Between Severely-To-Profoundly Hearing Impaired Children Utilizing Total Communication And The Oral/Aural Approach, Cathleen Pew Edwards

Dissertations and Theses

Prepositions are not only important in functional syntax; they also relate meanings associated with the concepts of place and time. Furthermore, prepositions are critical in such everyday activities as producing and comprehending directions, using maps and diagrams, and in the fields of mathematics and music. Inefficient use or misuse of prepositional spatial terms may hinder a child's progress in many areas. Expressive acquisition of function words, which include prepositions, has been described as significantly delayed in the hearing impaired populations.

The purpose of this study was to conduct a comparative preposition analysis between hearing impaired children using two different modes …


A Comparison Of The Time Taken To Administer And Analyze Phonologic And Phonetic Tests, Beverly Alexander May 1989

A Comparison Of The Time Taken To Administer And Analyze Phonologic And Phonetic Tests, Beverly Alexander

Dissertations and Theses

The purpose of this study was to determine if the time it takes to complete a phonological test was significantly different than the time it takes to complete a phonetic test. It was hoped this study would identify an instrument that the public school speech-language pathologist could use more effectively and efficiently to analyze phonologically-impaired children.


Frequency Responses Of Hearing Aids Coupled With Fm Auditory Trainers, Robert Bruce Morrison May 1989

Frequency Responses Of Hearing Aids Coupled With Fm Auditory Trainers, Robert Bruce Morrison

Dissertations and Theses

This study examined the frequency response characteristics of three behind-the-ear hearing aids alone and in combination with three FM auditory trainers. The hearing aids and FM auditory trainers were coupled using two different methods: direct audio input and personal mini-loop. Also, two different gain control settings were used. Frequency responses were evaluated using a template method specified in ANSI S3.22 1982 standards. A larger percentage of the personal mini-loop combinations failed to meet this ANSI standard as compared to the direct audio input combinations (72.3% vs. 50%). The frequency response curves for various combinations of hearing aids and FM auditory …


The Interaction Of Stimulus Rate And Polarity Effects On The Auditory Brainstem Response, Michelle Ann Nielsen Ziegler May 1989

The Interaction Of Stimulus Rate And Polarity Effects On The Auditory Brainstem Response, Michelle Ann Nielsen Ziegler

Dissertations and Theses

Research on the Auditory Brainstem Response (ABR) has been dominated by attempts to develop techniques to enhance the clarity of the ABR waveform and to define the parameters that separate normal from abnormal responses. While the effects of stimulus rate are clearly documented, the effects of stimulus polarity on the ABR are not. There may be an interaction of polarity and rate which accounts for the inconsistent results reported in the literature.

This study examined the effect of stimulus rate and polarity for waves I, III, and V, on the ABR latency, amplitude, and amplitude ratio. Rarefaction and condensation clicks …


Disfluencies In Normal Four-Year-Old Alaska Native And Caucasian Children, Annette Cameron O'Connell Apr 1989

Disfluencies In Normal Four-Year-Old Alaska Native And Caucasian Children, Annette Cameron O'Connell

Dissertations and Theses

The purpose of this study was to compare the frequency of occurrence of specific speech disfluencies in 4-year-old Alaska Native children to those of 4-year-old Caucasian children. Specifically, eight disfluency types were investigated: part-word repetition, word repetition, phrase repetition, interjection, revision-incomplete phrase, disrhythmic phonation, tense pause, and intrusive schwa. The questions addressed in the study were:

  1. Do 4-year-old Alaska Native children exhibit a higher frequency of disfluencies than 4-year-old Caucasian children?
  2. Do 4-year-old Alaska Native children exhibit a greater frequency of specific disfluencies, in terms of part-word repetition, word repetition, phrase repetition, interjection, revision-incomplete phrase, disrhythmic phonation, tense pause, or …


A Longitudinal Study Of The Disfluencies Of Four And Six Year Old Children, Mary B. Cox Apr 1989

A Longitudinal Study Of The Disfluencies Of Four And Six Year Old Children, Mary B. Cox

Dissertations and Theses

Investigations into the speech of normal children have indicated that disfluencies are common. It is important for the Speech Language Pathologist to have knowledge of normal disfluencies for differential diagnosis, parent counseling, and in order to plan strategies for intervention.

The purpose of this study was to compare the frequency of disfluencies in 4 year old and 6 year old normal male children to the frequency of disfluencies when they were 3 years old and 5 years old, respectively.

One year later, eighteen of the twenty normal male children study used in a previous study were reevaluated in this. At …


A Longitudinal Study Of Disfluencies In The Speech Of Normal Preschool Children, Susan Marto Crowell Apr 1989

A Longitudinal Study Of Disfluencies In The Speech Of Normal Preschool Children, Susan Marto Crowell

Dissertations and Theses

The process of differentially diagnosing a child who is experiencing temporary normal disfluency from one who is beginning to stutter could be made objective by the establishment of normative data on fluency development. To date, there are no standardized norms on the development of fluency in children. Current investigations have contributed greatly to expectations of certain types and amounts of disfluencies in preschool-age children. Most of the research, however, has focused on observing children at discrete age levels from 2- to 7-years-of-age. Only one longitudinal study to date has been reported. Additional longitudinal data of preschool-aged children would benefit the …


In Situ Measurements Of Two Amplified And One Acoustic Stethoscope, Sara Ruth Ann Oliver Feb 1989

In Situ Measurements Of Two Amplified And One Acoustic Stethoscope, Sara Ruth Ann Oliver

Dissertations and Theses

This study investigated the following questions: 1) What is the spectra of human heart sounds when transmitted to the listener's ear through amplified and acoustic stethoscopes? 2) How does the acoustic spectrum of normal heart sounds compare to the threshold of audibility for normal hearing sensitivity? 3) Do normal hearing listeners elect to listen to heart sounds at a higher intensity than the acoustic stethoscope is able to transmit?


Naive Listener Judgments Of Esophageal Air Intake Noise Acceptability, Janet Gordon Daucsavage Jan 1989

Naive Listener Judgments Of Esophageal Air Intake Noise Acceptability, Janet Gordon Daucsavage

Dissertations and Theses

The purpose of this study was to determine the judgments by naive listeners of the acceptability of esophageal air intake noise and compare those ratings to their judgments of overall esophageal speech proficiency. The primary question this study sought to answer was: Are naive listener judgments of overall esophageal speech proficiency significantly correlated with naive listener judgments of esophageal air intake noise acceptability? The secondary question asked was: Are naive listener acceptability judgments of air intake noise significantly correlated with sophisticated listener acceptability judgments of air intake noise?


The Use Of Auditory Brainstem Responses In Determining The Maximum Outputs Of Hearing Aids, Kathryn Jean Merry Jan 1989

The Use Of Auditory Brainstem Responses In Determining The Maximum Outputs Of Hearing Aids, Kathryn Jean Merry

Dissertations and Theses

Uncomfortable listening level (UCL) is a behavioral measure which is currently used to set the maximum outputs of hearing aids. This study explored the feasibility of prescribing the maximum outputs of hearing aids by using results obtained from auditory brainstern response (ABR) testing. More specifically, this study compared ABR wave latencies with behaviorally-measured UCLs for a single cycle 3 kHz stimulus in normal-hearing adults.


The Preparation And Involvement Of Oregon Speech-Language Pathologists In Dysphagia, Christine Marie Gaynor Jan 1989

The Preparation And Involvement Of Oregon Speech-Language Pathologists In Dysphagia, Christine Marie Gaynor

Dissertations and Theses

The purpose of this study was to determine the amount, type, and content of training acquired by SLPs presently working in dysphagia management, as well as their level of involvement. A questionnaire was sent to 97 Oregon SLPs. Of these, 77 (80%) responded, and 52 met criteria. The resulting data indicated that SLPs involved with dysphagia work in a variety of settings, including hospitals, nursing homes, home health agencies, and private practice. Seventy-two percent of the subjects have been involved with dysphagia management for less than 10 years; 79% treated between 1 and 10 patients for dysphagia the month prior …


Types Of Phonological Processes Occurring In Normal Black English Speakers, Eileen Rella Jan 1989

Types Of Phonological Processes Occurring In Normal Black English Speakers, Eileen Rella

Dissertations and Theses

Black English (BE) is a rule-governed linguistic system with its own phonology, syntax, semantics, and pragmatics. BE is a dialect, not a disordered variation of standard English (SE). When compared to SE, BE phonology has been described in terms of omissions, substitutions, and additions. This study looked at normal BE speakers in Portland, Oregon and described their dialectal differences in terms of phonological processes.


The Output Of Compression Hearing Aids With A Transient Input Signal, Michael Andrew Berg Jan 1989

The Output Of Compression Hearing Aids With A Transient Input Signal, Michael Andrew Berg

Dissertations and Theses

The output characteristics of five compression hearing aids in response to a transient signal were examined to determine if, the input-output function (i.e. output levels of the hearing aid as a function of input level) for a transient signal could be made to approximate that of a continuous signal, by activating the compression circuit with a second signal (activator). Input-output functions for three input compression and two output compression hearing aids were obtained in order to determine if: 1. the automatic gain control (AGC) was activated by the second signal and the transient signal output approximates that of a continuous …


Normative Data On The Auditory Memory Test Battery For Ages 9 Through 13 Years, Elisabeth Y. Carter Jan 1989

Normative Data On The Auditory Memory Test Battery For Ages 9 Through 13 Years, Elisabeth Y. Carter

Dissertations and Theses

Auditory short-term memory (STM) is important for speech and language development and for learning new information presented auditorily. Research has shown that auditory STM ability is of a developmental nature in the 5 through 8 year age range for a variety of auditory stimuli. Many tests and subtests are available to measure auditory STM ability, however one test, the Auditory Memory Test Battery (AMTB) measures auditory memory span and memory for sequence for 5 types of stimuli.

The purpose of this study was to collect normative data on the AMTB scores of normal 9 through 13 year old students and …


Speech Reception Via Bone Conduction, Sherry G. Morris Jan 1989

Speech Reception Via Bone Conduction, Sherry G. Morris

Dissertations and Theses

The purpose of this investigation was to determine if the performance-intensity function for spondees delivered via bone conduction (using the Radioear E-72 and Pracitronic KH-70) differed from the performance-intensity function for air conduction (using TDH-39 earphones). A secondary consideration addressed in this study was the comparison of the discrimination scores using the three transducers. Performance-intensity functions for spondee thresholds were calculated on 12 normal hearing subjects using two bone conduction vibrators, the Radioear B-72 and Pracitronic KH-70, and TDH-39 earphones. Results indicated that there was no significant difference between the performance-intensity function of speech via bone conduction as compared to …


Reading Comprehension In Dementia Of The Alzheimer's Type : Factual Versus Inferential, Donna Jensen Graville Jan 1989

Reading Comprehension In Dementia Of The Alzheimer's Type : Factual Versus Inferential, Donna Jensen Graville

Dissertations and Theses

The purpose of this study was to investigate the reading comprehension abilities of those with mild and moderate dementia of the Alzheimer's type (DAT) and compare their performance to that of a sample of non-demented elderly. Thirty-eight male subjects were used, 20 non-demented elderly, nine mild DAT and nine moderate DAT. All were administered level B of the NRST. This test contains questions requiring three levels of inference: literal, translational, and high-level inference.


Coverbal Behavior Of Aphasic And Right Hemisphere Damaged Subjects In Conversation, Jill Duvall Nov 1988

Coverbal Behavior Of Aphasic And Right Hemisphere Damaged Subjects In Conversation, Jill Duvall

Dissertations and Theses

The frequency and duration of six coverbal behaviors were examined in two experimental groups and one control group. Conversational samples of ten aphasic subjects, ten right hemisphere damaged (RHD) subjects, and ten matched, non-brain damaged (NBD) control subjects were scored for frequency and duration of eye contact, head nod, head shake, head tilt, smile and eyebrow raise. Only the frequency of smile was found to differ significantly; the RHD subjects smiled less often than either of the other two groups.


An Investigation Of The Effect Of Using Varying Stimuli To Assess Normal Children's Comprehension Of Five Locative Prepositions, Kathleen G. Versteeg Jul 1988

An Investigation Of The Effect Of Using Varying Stimuli To Assess Normal Children's Comprehension Of Five Locative Prepositions, Kathleen G. Versteeg

Dissertations and Theses

A recurring concern in recent research appears to be the role that assessment variables play in accurately measuring children's knowledge and use of prepositions. Age and order of acquisition of prepositions has become a dynamic rather than static standard, as different ways of assessing prepositions also give different results. These researchers have investigated assessment variables such as context (picture, object, no context) and response (self actions, manipulating, pointing) in assessing normal children's understanding and use of prepositions. Most have considered these variables separately, but a few have contrasted a limited number of variables with significant results for some age groups. …


Communication And Socialization Profiles In Toddlers With Expressive Language Delay, Shawn Spangle-Looney May 1988

Communication And Socialization Profiles In Toddlers With Expressive Language Delay, Shawn Spangle-Looney

Dissertations and Theses

The purpose of this study was to compare expressive communication, receptive communication, and socialization achievement in 18- to 34-month-old ELD toddlers to the same skills in normally-speaking children. The questions this study sought to answer were, how do the three skill areas in ELD toddlers compare with the same skills in normal toddlers?, will ELD subjects evidence specific profiles of deficits involving not only expressive but receptive and social skills as well? and, within the ELD subjects will two subgroups emerge, one group having poor expressive skills only, and a second group having deficits in addition to expression.


A Comparison Of Three Methods For Measuring The Attenuation Provided By Insert-Type Hearing-Protective Devices, Lois Jeanne Gaier Feb 1988

A Comparison Of Three Methods For Measuring The Attenuation Provided By Insert-Type Hearing-Protective Devices, Lois Jeanne Gaier

Dissertations and Theses

To effectively implement an occupational hearing conservation program, employers must know the amount of attenuation (noise reduction) provided by the hearing protective devices used by their employees. Currently standardized test methods, performed under laboratory conditions, cannot be easily implemented in industrial settings, and previously proposed field methods have depended upon the use of special headphones which are not typically available in the workplace. These problems have led many occupational hearing conservationists to use standard audiometric headphones to evaluate the attenuation provided to employees using insert-type hearing-protective devices. There has, however, been little research into the validity of using standard audiometric …


A Study Of The Capability Of The Computerized Visi-Pitch When Investigating Prosodic Features Of Motherese, Denise Leslie Clemens Jan 1988

A Study Of The Capability Of The Computerized Visi-Pitch When Investigating Prosodic Features Of Motherese, Denise Leslie Clemens

Dissertations and Theses

With commercial availability of non-real and real-time spectrum analyzers, the speech-language pathologist has the means to objectively extract and measure pitch taken from speech samples. Though both types of spectrum analyzers provide the clinician with viable methods of measuring fundamental frequency and frequency range values, pitch extraction using real time allows for greater efficiency in acoustic measurements. The Kay Elemetrics Visi-Pitch is one such real-time spectrum analyzer that is less expensive and more accessible than other real time speech science hardware. The purpose of this study was to investigate the capability of a computerized Visi-Pitch to reflect elevation of fundamental …


The Differential Role Of The Ssi With Normal Preschool Children, Caroline Joy Semler Nov 1987

The Differential Role Of The Ssi With Normal Preschool Children, Caroline Joy Semler

Dissertations and Theses

The onset of stuttering usually occurs between two and six years which is the same time most children exhibit normal disfluencies often making it difficult to differentiate between normally disfluent children and incipient stutterers. Clinicians need information on the types and frequencies of disfluencies exhibited by normal preschool children in order to determine if a child is more likely to be an incipient stutterer or normally disfluent child. Some clinicians feel uncomfortable relying on past literature since there is a limited amount of information available and the studies have shown a considerable amount of variability in the types and frequencies …
