The purpose of this study was to compare the expressive and comprehensive language structure skills of a selected sample of normal males and adolescent autistic males, using the Michigan Picture Language Inventory (MPLI) as the investigating instrument in order to determine if a statistically significant difference existed between the two groups. The autistic and normal subjects were matched for mental age scores within plus or minus two months as measured by the Peabody Picture Vocabulary Test (PPVT), Form B.

Seven autistic male and seven normal male subjects were selected from the greater Portland metropolitan area to be included in this …

Test-Retest Performance Of Males And Females On A Verbal Dichotic Listening Task, Linda Kay Johnson

Speech and Hearing Sciences ETDs

Previous research has established that when two speech signals are presented dichotically, normal listeners tend to report those stimuli presented to the right ear more accurately than those presented to the left. This has generally been interpreted as reflecting the primacy of contralateral auditory pathways and left hemisphere dominance for language function. Although many dimensions of the dichotic listening procedure have been subjected to experimental manipulation, little attention has been directed toward the investigation of performance differences between males and females or the reliability with which listeners perform. The present study was designed to examine these two areas more closely, …

The Effect Of Favorable Video Feedback On A Person's Self Concept, Antonio B. Rey

Speech and Hearing Sciences ETDs

Previous research concerned with the relationship between video feedback and self concept indicates that video feedback can affect a person’s perception of self. Based on self concept theories which suggest that positive or negative evaluations from others tend to become self-evaluations, the purpose of this study was to investigate the effect of video feedback, self-appraised as favorable, on o person's self concept.

A Comparison Of Two Systems Used In The Electro-Acoustic Evaluation Of Hearing Aids, Sallie Ann Frye

Dissertations and Theses

Validation Of The Oregon School Entrance Speech Screening Test, Patricia Ann Hamilton

Dissertations and Theses

This study was designed to validate a speech screening device entitled the Oregon School Entrance Speech Screening Test. The OSESST was developed to identify quickly those children entering first grade who are in need of speech and language intervention. The present study sought to determine what proportion of children with speech and language disorders was not detected by the screening test and what proportion of children without speech and language disorders failed the OSESSI. In addition, this study undertook to determine whether results of this investigation are consistent with those obtained on the OSESST in areas of articulation, syntax, language …

Teaching Hearing-Impaired Children Language Through The Use Of Musical Rhythm, Naomi Anne Banducci

Dissertations and Theses

While several authors have indicated specific methods for teaching rhythm, there is no single, comprehensive source available which could serve as a teaching guide in this important area of aural rehabilitation. The current paper represents an initial attempt to fulfill this need. The purpose ot this paper is to provide a survey of the different methods and avenues for teaching the rhythm of language to hearing impaired children.

Right-Left Visual Field Performances Of Congenitally Deaf And Normal Hearing Subjects, Merle Applebaum-Rosenberg

Speech and Hearing Sciences ETDs

The notion of cerebral dominance has been explored since the time of Broca. Two non-invasive techniques designed to assess hemispheric dominance have subsequently been developed. These two methods are commonly referred to as dichotic listening (simultaneous auditory stimulation) and rapid visual field stimulation (tachistoscopic viewing).

It has been found in dichotic listening studies that when verbal material is presented simultaneously to both ears, the stimuli are correctly identified most often in the right ear. Similar results have been found in tachistoscopic studies, with verbal material eliciting a right visual field advantage. Collectively, these findings have been used to support a …

A Comparison Of Aphasic And Non-Brain Injured Adults On A Dichotic Cv-Syllable Listening Task, Janet E. Shanks

Speech and Hearing Sciences ETDs

Normal listeners traditionally show a right ear preference for dichotically presented speech stimuli, and a left ear preference for dichotically presented non-speech stimuli. Although some inter-subject variability is observed within and between groups of non-brain damaged subjects, the performance of the group as a whole is rather predictable and homogeneous. However, results from experiments in which brain damaged subjects have been studied have been less straightforward. Although left brain damaged subjects have consistently shown a bilateral deficit in reporting dichotic speech stimuli, a great deal of variability in performance is observed within the groups. Further study of brain damaged individuals, …

A Comparison Of Two Methods Of Speech Reception Threshold Measurement, Richard Allen Oge

Speech and Hearing Sciences ETDs

In an attempt to discover the current methods being utilized in clinical audiology, Martin and Pennington (1971) surveyed a large number of audiologists concerning their administration of the hearing tests available to them. One of the findings of this survey indicates that a number of different procedures are being used to obtain the speech

reception threshold (SRT). This fact strongly suggest that the SRT estimate obtained on a given subject may vary between clinics, not because of the subject's hearing sensitivity but because of the audiologist and his procedure of acquiring this measure.

Alternate Monaural Loudness Balance For Tones With Different Duty Cycles, Sharon Ann Dixon

Speech and Hearing Sciences ETDs

The effect of duty cycle, or the percentage of time a signal is presented, upon the perceived loudness of a pulsed tone was studied utilizing an alternate monaural loudness balance technique. The single ear was employed in an attempt to eliminate any possible artifacts of binaural interaction upon the perceived loudness of pulsed signals.

The factors under investigation included: the difference in duty cycle between a fixed-intensity reference signal and a variable-intensity comparison signal; the use of a relatively high versus a relatively low duty cycle reference signal; and the effect of time after commencement of the loudness balances. Differences …

Verbal Operant Conditioning And Response-Reinforcement Contingency Awareness, Val R. Smith

Speech and Hearing Sciences ETDs

The following problem was investigated: can persons be conditioned to emit a verbal response without their awareness of the response-reinforcement contingency? It was hypothesized that when a “set to problem solve,” is not induced and experimenter effect due to the subject­experimenter interaction is eliminated, subjects are conditioned to emit a verbal response without an accompanying contingency awareness. Three experiments were conducted in order to test the hypothesis. In experiment 1 an attempt was made to condition vocal response length using a visual reinforcer. In experiments 2 and 3 an attempt was made to condition use of specific pronouns using a …

An Investigation Of Vocational Rehabilitation Among Northwest Laryngectomees, Susan L. Leonti

Dissertations and Theses

Rehabilitation for patients recovering from surgical removal of the larynx should include vocational considerations with accompanying economic modifications. The literature pertaining to rehabilitative management of laryngectomees revealed numerous investigations concerned with physical restoration, remedial speech training and psycho-social adjustment, while few studies have been conducted concentrating upon vocational consequences of a laryngectomy.

The primary purpose of this investigation was to examine the pre- and post-operative vocational status of laryngectomized patients residing in the Northwestern section of the United States.

Verbal Sequencing Ability As A Predictor Of Reading Disability, Paul Elmer Quin

Dissertations and Theses

Early identification of children with reading and learning problems seems imperative. By using early identification predictors, a high risk group of children with possible reading problems could be located. This would facilitate placement and appropriate educational strategies for this group of children. By proper placement and planning, educators then would be able to set up remedial and/or preventive programs for these children before the pattern of unsuccessful attempts and improper training becomes irreversible. This study was designed to determine if verbal sequencing ability was a valid predictor of reading ability for a group of 31 preschool children. Secondarily, the investigation …

An Investigation Of The Relationship Between Accented Words In The Spontaneous Speech Of Stutterers And The Frequency Of Stuttering Occurrence, Cherie Richardson

All Master's Theses

This study explored the influence of word accent upon the precipitation of audible stutterings in the spontaneous speech of five adult male stutterers. The results indicated that three of the subjects stuttered with significant frequency upon accented words and two of the subjects evidenced a definite tendency to stutter on accented words. It was proposed that accented words may be a locus of stuttering in sentences and phrases of spontaneous speech in addition and perhaps relative to the four loci postulated by earlier research.

An Investigation Of Between-Ear Tympanometry Measures In Normal-Hearing Young Adults, Barry Lynn Kimmel

Dissertations and Theses

In recent years, tympanometry has been used to provide objective and definitive information regarding the status of middle ear conditions and functions. The present standard for tympanometric normalcy is based upon between-subject measures. This standard, however, does not allow precise differentiation between normal and pathological tympanometry curves. A within-subject comparison of right and left ear tympanometry curves of normal-hearing subjects could provide a narrow standard of tympanometric normalcy which would be more useful in differentiating between pathologic and non-pathologic middle ear function. The within-subject relationship between tympanometry curves for right and left ears was investigated by comparing the individual right …

Effects Of Certain Linguistic Parameters Upon The Responses Of Preschool Subjects To Specific Dichotic Listening Tasks, Peggy J. Weber

Dissertations and Theses

Listening, as a communication skill, is an essential factor in the normal language development of the' child. Until recently, however, there has been very little research conducted concerning the linguistic parameters that influence the ability to listen. Thus, this investigation was designed to study the effects of two linguistic parameters, construction and semantic constraints on the verbal responses of preschool children in a dichotic listening task.

Fifteen children, between the ages of 5-3 to 6-8, were presented with four dichotic listening tasks consisting of 80 stimuli, (40 sentences and 40 pseudo-sentences). The children were asked to report the message delivered …

An Investigation Of Temporary Threshold Shift Among Helmeted Motorcycle Riders, Alamander Hicks

Dissertations and Theses

The purpose of the present study involved the investigation of the significance of wind noise as a contributing factor toward temporary threshold shifts among a select sample of motorcycle riders. Five normal-hearing, helmeted, female subjects were administered pure-tone air-conduction hearing tests immediately before and within 2 minutes after exposure to three noise-related aspects of motorcycle riding. The amount of hearing loss present at 3k, 4k and 6k Hz after each 20 minute exposure condition was recorded as the TTS for that subject. The three conditions consisted of motorcycle noise only, wind noise only and motorcycle and wind noise combined. A …

Wind Noise: Its Effect On Human Audition, William Roy Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An examination was made of the acoustic characteristics of wind turbulence generated noise in a car traveling at 70 mph over smoothly paved highway with the driver's window down. The overall noise level was found to be at 112 dB SPL with the predominance of energy in the low frequencies. The study was concerned with the effects of such noise on human audition in terms of temporary threshold shift.

Twenty normal hearing young adults were exposed to a tape recording of wind noise for 15 minutes. Post-exposure auditory thresholds at seven discreet frequencies were compared to pre-exposure auditory thresholds at …

A Comparison Of Speech Audiometric Performance Of Hypacusics With Clinic-Fitted Hearing Aids And With Master Hearing Aid, Kent Jay Nielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Clinical audiologists at Utah State University have been using a master hearing aid as a basic part of hearing aid evaluation procedures. To ascertain the usefulness of the master hearing aid in predicting patient success with a wearable hearing aid, 20 subjects were given speech audiometric tests under the following conditions: (1) without amplification; (2) with the headset system of the master hearing aid (a system which utilizes chassis mounted microphones and external receivers of the type used with body-worn hearing aids); (3) with the ear-level system of the master hearing aid (a system which utilizes a microphone and receiver …

An Assessment Of Gestural And Pantomimic Deficit In Aphasic Patients, Len W. Pickett

Speech and Hearing Sciences ETDs

A review of the literature suggests two explanations for gestural deficits in the aphasic patient. One view of the problem suggests that gestural impairment in the aphasic patient is related to a general communicative deficit. Another concept of the problem which has received more scientific support suggests that gestural deficit is secondary to a limb apraxia and is quite independent of the severity of aphasia.

The present study, therefore, was designed to investigate three primary questions:

1. Can a gestural test battery be developed which can reliably measure the gestural ability of aphasic patients?

2. Is there a relationship between …

Comparison Of Amounts Of Verbal Response Elicited By A Speech Pathologist And A Mother In The Clinic, Sherry Lee Nelson

Dissertations and Theses

One of the primary responsibilities of a speech pathologist is the assessment of a child's language. Many studies have been done in the area of language development. The results of these studies have varied causing concern among researchers over the validity of the data gathered. Many factors that could affect the results of previous research have been investigated. Until recently, however, there has been relatively little research about the effects of examiner differences on the results of language assessments.

Research in the area of examiner differences has resulted in the discovery of factors which could affect the results of language …

The purpose of the paper is to determine if students who are poor spellers have poor auditory discrimination. Recommendations included the use of a spelling test which requires greater auditory discrimination than the Kottmeyer Spelling Test. Also recommended is a correlation study using primary students as the population.

The Effect Of Labeling Disfluencies As 'Stuttering' And Contingent And Yoked "Wrong" On The Disfluencies Of Normal Speakers, Dennis Ray Staines

Dissertations and Theses

A labeling variable suggested by Wendell Johnson's "diagnosogenic" theory of the onset of stuttering was included in this study of the disfluencies of normal speaking college students in order to explore further the hypothetical relationship between normal disfluency and the onset of stuttering. A total of 60 Ss were randomly assigned to the following groups, each containing 10 Ss: I. Labeling Chastisement plus Contingent "wrong;" II. Labeling Chastisement plus Yoked (non-contingent) "wrong;" III. Labeling Chastisement - No "wrong;" IV. No Labeling Chastisement Contingent "wrong;" V. No Labeling Chastisement - Yoked "wrong;" VI. No Labeling Chastisement - No "wrong" …
