A Validation Study Of The Screening Test For Developmental Apraxia Of Speech, Deborah L. Thorsen

Dissertations and Theses

The term "developmental apraxia of speech" (DAS) has been a confusing one since Morley, Court and Miller (1954) first applied it to articulatory patterns of a specific group of children. Until recently, the differentiation of diagnostic features of DAS in children as compared to other articulatory disorders has been difficult. One evaluation tool, developed by Blakeley (1980), to assist in differential diagnosis of DAS is the Screening Test for Developmental Apraxia of Speech (STDAS). This study examined the validity of this tool by comparing its results with the evaluations by three Speech-Language Pathologists knowledgeable in the area of developmental and/or …

On The Memory Code In Serial Feature-Positive Discriminations, Robert S. Mccann

Theses and Dissertations (Comprehensive)

The aim of the present research was to examine the nature of the memory code that contributes to performance in a serial feature-positive discrimination. In order to test the hypothesis that a reinforce expectancy based on the first-order association between feature element and reinforce defines the content of the code, different groups of rats received various forms of pretraining involving either the feature element or the common element, or both. For some groups the feature element was trained as a CS+, while for others it was trained as a CS-. In addition, some groups received training establishing the common element …

The Relationship Of Lean Body Mass To Resting Metabolic Rate, Maryann Butler

Dissertations and Theses @ UNI

Previous investigators have established predictors affecting basal metabolic rate. These include body size, age and sex, surface area, temperature and environment, and exercise. Conflicting data have been reported concerning the expression of basal metabolism in units of square meters of surface area. It was the purpose of this study to observe the relationship of lean body mass (LBM) to resting metabolic rate (RMR) in college-age males of high lean body mass and low lean body mass. A second purpose was to determine the validity of a relatively new method of measuring resting metabolic rate using a whole body calorimeter (WBC). …

Dance Therapy And Self-Concept Change In Psychiatric Patients, Cheryl Jeanne Hall

Dissertations and Theses

This study investigated the effects of various forms of therapy (individual, occupational, and dance) on self-concept. Subjects were 29 psychiatric patients at Providence Medical Center who volunteered to participate in this study. The Tennessee Self-Concept Scale (TSCS) was used to measure self-concept both at time of admission and prior to discharge. The data were analyzed in a step-wise multiple regression to determine which of the various forms of therapy are the best predictors of self-concept at second TSCS application. The results of the step-wise multiple regression did not support the hypothesis that exposure to dance therapy would be a significant …

Studies Of Plasma Membrane Domain-Specific Molecules In Isolated And Cultured Rat Hepatocytes, Pamela Leslie Zeitlin

Yale Medicine Thesis Digital Library

Single rat hepatocytes, prepared by collagenase perfusion of liver, lost the three morphologically and functionally distinct plasma membrane domains that exist in situ (sinusoidal, bile canalicular, and lateral). Hepatocytes placed in monolayer culture re-established morphologically distinct plasma membrane regions analogous to the original three domains. The behavior of several domain-specific markers was studied in these cells. The asialoglycoprotein (ASGP) receptor, an integral membrane glycoprotein normally restricted at the surface to the sinusoidal domain in situ, was retained in both single hepatocytes (> 95%) and in cells after 24 hr in monolayer culture but at lower levels. Cytochemistry with asialo-oroso-mucoid-horseradish peroxidase …

A Histopathological Assessment Of The Effects Of Streptozotocin-Induced Diabetes On The Ears Of Chinese Hamsters, Karen Ailsworth

Masters Theses

Research has produced evidence associating progressive, bilateral, sensorineural hearing loss with diabetes mellitus in human and animal subjects. The microangiopathy which is presumably the cause of hearing loss appears similar to the microangiopathy leading to retinal and renal atrophy.

In the present study the temporal bones of six streptozotocininduced diabetic Chinese hamsters and six nondiabetic Chinese hamsters were histologically processed. Sections stained with hematoxylin and eosin were assessed for total auditory and vestibular otopathology and revealed no statistically significant differences between the two groups. Sections stained with periodic acid-Schiff's were evaluated for vascular basement membrane changes and revealed no statistically …

A Study Of The Validity Of The Global Assessment Scale, Daniel J. Dekker

Dissertations

The study evaluated the concurrent validity of the Global Assessment Scale (GAS), a rating scale which is used to measure overall severity of psychiatric disturbance in program evaluation systems and in research studies. Validity was evaluated by comparing GAS ratings of 60 community mental health outpatients to scores on the MMPI.

The literature review indicated that the GAS has been used in over 90 studies. Thirty-one inter-rater reliability coefficients cited indicated an acceptable median reliability of .80, but studies relevant to the GAS's validity were sparse and marginally supportive. The GAS was utilized primarily to evaluate change due to psychotherapy …

The Effect Of Interpolated Continuous Reinforcement Following Variable Ratio Reinforcement On Resistance To Extinction, Christine Miara

Graduate Theses

The effect on response rates during extinction of interpolating seven continuous reinforcement sessions after varying numbers of VR-25 sessions was investigated. Rats received either seven, fourteen, or twenty-one sessions of a VR-25 schedule followed by seven sessions of continuous reinforcement. There were three rats in each group. The rats then experienced seven sessions of extinction. All sessions were 30 minutes long." The results showed that rats that received the VR-25 schedule for 21 sessions made the roost responses over the seven extinction sessions. * Rats that received seven sessions of VR-25 made the least number of responses during extinction. The …

Identifying Jungial Personality Type By The Instrument Of Self-Report, Charles Clay Livingston

Masters Theses

This paper examines the instrument of self-report and its use in identifying and measuring the elements of the personality as defined by C. G. Jung. Jung's theory of personality is briefly explained, and self-report as a general instrument of personality assessment is critically examined. Selected research on the construction and use of self-report tests is reviewed and critically evaluated. The author asserts that the bipolar assumption that is often implicit in the construction of test items is not representative of the personality as Jung portrayed it. The author suggests revisions in the construction of test items and a scoring gradient …

Long Slow Distance Running As A Treatment For Moderate Depression Of Outpatients, Dalene Degraaf Vandenhoek

Masters Theses

The purpose of this study was to determine the effect of "long slow distance" (LSD) running as a treatment for moderate depression. Clients diagnosed with "moderate primary depression" were randomly assigned to one of two treatments. Individuals receiving the running treatment walked and ran slowly for forty minutes three times a week for ten weeks. Those receiving psychotherapy participated in behavior therapy one hour a week for ten weeks. According to biweekly scores on the Symptom Checklist-90 and Beck Depression Inventory, the anxiety and depression of the clients who ran improved as much as those receiving behavior therapy.
