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, …

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 …

Depression In Elderly Men Following Transurethral Prostatectom, Brenda Leach Allocco

Loma Linda University Electronic Theses, Dissertations & Projects

This study was concerned with the problem of depression among elderly patients following surgery. The purpose of the study was to find out if older men following transurethral prostatectomy experienced a higher level of depression than normal elderly people in the general population. An attempt was made in the study to suggest factors in the patients' illness or environment which may have influenced the amount of depression they experienced.

Thirty patients, sixty-five years or older, were included in the study sample. Depression was measured by a self-rating depression scale (Zung) three weeks following their operations. Other facts about the patients …

A Study Of Variability In Locating The External Reference Point For Central Venous Pressure Determination, Joyce Johnson Drake

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory study was conducted to determine the variability occurring among intensive care nurses in locating, with two methods, the external reference point for central venous pressure (CVP) determinations. In the literature on CVP and on CVP value discrepancies, no reports were found of studies related to variability among medical personnel in locating the point.

The nurse participants in this study were thirty-one intensive care nurses who routinely were involved in CVP monitoring and marking reference points on patients in two surgical intensive care units. Thirty-two volunteer, non-hospitalized subjects, ages 18-85, sixteen males and sixteen females, with varying body builds …

The Effects Of Atropine On The Growth And Respiration Of Two Species Of Bacteria Normally Inhabiting The Human Gastro-Intestinal System, Mary M. Ramos

Theses & Dissertations

It is the purpose of this study to determine whether the drug atropine has an effect on bacteria found normally inhabiting the human body, most specifically the gastrointestinal system. Atropine is one of the oldest drugs in medicine. It is derived from the roots and leaves of solanaceous plants such as henbane and Jimson weed. Atropine is often termed a belladonna alkaloid because it can also be found in the deadly nightshade plant, Atropa belladonna. Atropine is a highly competitive antagonist of acetylcholine at receptor sites in smooth muscles, cardiac muscle, and various glandular cells (5). Therefore, its effects are …

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). …

Experimentation To Develop Procedures To Be Used In The Investigation Of The Effects Of Restriction On The Unmodified Dna Of The Bacteriophage Lamda, John Haynes

Honors Theses

The results of experimentation approximately twenty years ago with variuos bacteriophages by Ralston and Krueger¹⁶, Anderson and Felix¹, Luria and Human¹², and by Bertani and Weigle² have shown that the host range of a given phage depends directly on the bacterial strain on which the phage has last propagated. This event came to be known as host-induced modification or host-controlled variation. As this phage host range is controlled by the host environment and can be altered from one generation to another it has, according to Luria, made microbiology "the last stronghold of Lamarckism" …

Cephalometrics For The Oral Surgeon In The Diagnosis Of Facial Deformities, Frederick J. Mantz

Loma Linda University Electronic Theses, Dissertations & Projects

Surgical orthodontics presents a challenge to the oral surgeon. By the nature of the oral surgeon's training and discipline he should be the one best qualified to treat the surgical aspect of the surgical orthodontic case. The establishment of a proper diagnosis and means of communication between the oral surgeon and orthodontist are essential in achieving a good final result for the surgically treated case. Fortunately, a scientific method of diagnosis is available that can provide both specialties with a common language. Computerized cephalometric analysis can provide the diagnosis and link of communication for the discussion of goals and treatment. …

The Effect Of Post-Operative Use Of Chlorhexidine On Periodontal Regeneration In Monkeys With Chronic Bifurcation Defects, J. Pat Bishop

Loma Linda University Electronic Theses, Dissertations & Projects

Periodontal regeneration and inflammation was evaluated histometrically in 36 paired teeth in six macque(sic) monkeys with chronic bifurcation defects. Daily topical TL Chlorhexidine was applied to one-half of the teeth, saline to the other half for six weeks after the bifurcation defects were surgically debrided. Measurements were made from a section taken from the mid-bifurcation for each tooth. The results demonstrated no significant difference in the area of inflammatory response or the degree of regenerative capacity of post-operative healing between Chlorhexidine treated and paired nontreated control teeth.

Viability Of Dentin In Rats Incisors : Fluid Movement In Pulpless, Endodontically Treated, And Normal Teeth In Rats, Maria Luisa Canales

Loma Linda University Electronic Theses, Dissertations & Projects

It is a well established fact that there is a fluid transport system through the dentin, however to the present time very little has been done regarding this system in teeth that have been endodontically treated.

The present work was conducted in vivo using the lower incisors of rats as the medium for the study.

A selected number of Sprague Dawley rats (36 animals), whose average age was 60 days, and whose body weight averaged about 180 grams, were given an anesthetic of Sodium Pentabarbitol, .05 to .07 ml. per 100 grams body weight. This anesthetic was injected intraperitoneally.

A Method Of Analyzing Mandibular Movement, Richard B. Mccoy

Loma Linda University Electronic Theses, Dissertations & Projects

Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.

The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …

Development And Analyses Of A New Ideal Finishing Appliance, Robert M. Asatani

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this paper is to introduce a new theoretical finishing appliance which should reduce the problems encountered during finishing with the present appliances. Maxillary and mandibular Buccal Arch Positioner appliances were constructed on a model that could deliver custom-designed force magnitude and direction to each tooth.

The mean force and displacement of 1 mm. for each flexible component were quantitated individually while all other flexible components were in a passive bracket position to see if the force magnitude to each tooth was constructed properly. Various hypothetical situation were quantitated. Unilateral mesial vectors caused skewing and labial displacement of …

Effect Of Tooth Cleaning Procedures On Gingival Sulcus, Klaus D. Wolfram

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of tooth cleaning procedures on the gingival sulcus has been investigated. Clinically healthy gingivae from thirty-two maxillary anterior teeth of eight individuals served as experimental sites. Measurements were obtained from zinc-oxide eugenol impressions of the sulcular area. Subsequent to periods of toothbrushing, the presence of a gingival sulcus could generally be demonstrated. This was observed for the Roll as well as for the Bass method of brushing. Following no-brushing periods, during which chlorhexidine plaque control was exercised, a reduction in sulcus depths and often a disappearance of the sulcus was noted. It is suggested that the presence of …
