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, …

Effects Of Semantic Associational Strength And Verbal Sequence Length On The Auditory Comprehension Of Aphasic Adults, Laurel J. Brown

Dissertations and Theses

The purpose of this study was to investigate the effects of semantic associational strength (SAS) upon adult aphasics' auditory comprehension abilities. Twenty-eight adult aphasics (25 males and 3 females) and 12 normal control subjects were presented three experimental tasks, each containing 45 items. Experimental task 1 contained single word picture sets of high SAS, moderate SAS, and low SAS words. Experimental task 2 contained two word picture sets of high, moderate, and low SAS words, and experimental task 3 contained three word picture sets of high, moderate, and low SAS words. Subjects heard one, two, and three word verbal sequences …

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 Experimental Study Of The Impact Of Clinical Psychodiagnosis, Diagnostic Concept And Dogmatism On The Perception Of Psychopathology., Jane Ellen Stilwell Smith

Student Work

The subject of psychiatric diagnosis and the ramifications of a person being labeled as "mentally ill" has attracted increased attention in the past decade. Personal testimony from psychiatric patients about the difficulty in securing employment, returning to familiar abodes, and re-entering a scholastic environment because of rejection by "normal" society, has been documented in confidential case files, witnessed by friends and relatives, and published for lay consumption (Rubin, 1960; Salinger, 1951; and Green, 1964). Other literature has been devoted to the apparently negative psychological aspects of being an in-patient in a mental institution (Caudwill, 1958; Goffman, 1961; and Gordon, 1971). …

An Investigation Of Handedness And Its Relationship To The Site Of Contact Ulcers, Colleen S. Colleary

Dissertations and Theses

This investigation attempted to determine the relationship of the site of contact ulcers and subject’s handedness. Literature concerned with contact ulcers has indicated that cerebral dominance tends to determine the site of the lesion. Four research questions were posed, two questions were presented in the form of the null hypothesis. The questions were: (1) Is the proportion of right-handed subjects with left-sided ulcers equal to the proportion of left-handed subjects with left-sided ulcers? (2) Is the proportion of right-handed subjects with right-sided ulcers equal to the proportion of left-handed subjects with right-sided ulcers? (3) Will the site of contact ulcers …

Effects Of Speaker-Sex-Difference On Listeners' Perception Of Vocal Roughness In Normal Vowel Productions, Patsy J. Phillips

Dissertations and Theses

The purpose of this study was to investigate the effects of speaker-sex-difference on listeners' perception of vocal roughness in the vowel [ӕ] produced by normal male and female speakers. In a previous investigation by Wendahl (1963) it was found that when listening to two synthesized vowels, of equal aperiodicity, judges tended to rate the lower pitched vowel as being more vocally rough. If this is true for listeners' perception of human vowel productions as well then it might be advantageous for voice clinicians, when making vocal roughness assessments, to regard male and female speakers as two separate populations in view …

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 Ability To Predict The Frequency Of Occurrence Of Words Between Normal And Articulatory Defective College-Age Individuals, William Joseph Divers Iii

All Master's Theses

The purpose of this study was to see if normal speakers and misarticulators differentially predict the frequency of occurrence of 80 words containing one or more of the five most frequently misarticulated speech sounds. The 80 words were selected from a study by Ausherman and Black. The subjects were 20 college-age individuals, ten with normal articulation and ten with articulation disorders. There were five males and females in each group.

All subjects predicted the frequency of occurrence of 80 words on the basis of an eight-point scale. Error scores were computed, used as a criterion measure, and statistically analyzed and …

A Study Of Latency Of Response In A Speech Sound Discrimination Task, Constance R. Heaton

Dissertations and Theses @ UNI

The results of many traditional speech sound discrimination studies have been inconclusive as to the relationship between articulation skill and discrimination ability . Further , these results have allowed researchers to only speculate as to the nature of the cognitive processing involved in making a choice decision . Recently some investigators in speech pathology have measured reaction time in speech sound discrimination studies . The results suggest that reaction time can be useful in the analysis of item difficulty as related to errors in discrimination. The purpose of the present study was to compare on a "same" - "different" sound …

Warble Tone As An Audiometric Stimulus, Gary Dean Dockum

Dissertations and Theses @ UNI

The warble tone, as an auditory stimulus, is apparently being used in a number of clinical settings. However, it is being used without knowledge of possible threshold differences which may exist between it and the pure tone stimulus. Recent studies comparing the two stimuli have been limited to extremely small samples and to only trained listeners. Also, they provide mostly theoretical information based on the effect of various warble parameters on warble tone thresholds. The purpose of the present study was to compare obtained pure tone and warble tone thresholds for a large group of normal-hearing inexperienced listeners while using …

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.
