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

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

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 …

One, Two, Buckle Your Shoe: Numbering Systems In Asl, Jan Kanda Humphrey

Course Materials

Skill building lesson focuses on using numbers for counting, relaying general information, ranking and ordinal numbers; on how to sign numbers showing age, and other questions regarding numbering systems used for age, money, clock and calendar time; and on how to produce numbers within pronouns, measurement, sports, and mathematics. Also this tape demonstrates the use of numbers when describing people in relation to height and weight.

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

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?

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.

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

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 …

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.
