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 …


The Effect Of A Video Presentation And Reference Guide Manual Of Helicopter Safety Instruction On The Knowledge Base Of Medical Transport Nurses, K. Linda Stickney Jun 1989

The Effect Of A Video Presentation And Reference Guide Manual Of Helicopter Safety Instruction On The Knowledge Base Of Medical Transport Nurses, K. Linda Stickney

Dissertations and Theses

The purpose of this study was to evaluate the results of trained transport nurses being oriented to a new helicopter by a video presentation and reference guide manual educational program when compared with trained transport nurses being trained by actual hands-on demonstration. Using a posttest-only design and the t test for independent samples, it was found that the two groups of nurses did not differ statistically (t (9) = 0.318, p < .051).


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

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.


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 …


Toward Predicting Completion Of Substance Abuse Treatment, Rebecca Lee Bragg Jan 1989

The subjects were patients from a private, non-profit, medically based, residential program. Nine demographic characteristics were abstracted from the charts on file for the patients at the treatment center. Two groups of 45 patients each were selected from the inpatient population. One group, the Completed Treatment group, comprised patients who had completed the 28 day program. The second group, the AMA Discharge group, comprised patients …


Maternal Linguistic Input To Normal And Expressive Language Delayed Toddlers, Terril Joy Elwood Jan 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 Longitudinal Study Of The Disfluencies Of Four And Six Year Old Children, Mary B. Cox Jan 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.

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 …


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


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


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 …


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

A Longitudinal Study Of Disfluencies In The Speech Of Normal Preschool Children, Susan Marto Crowell Jan 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 preschoolaged children would benefit the …


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.
