Mdma And Learning: Effects Of Acute And Neurotoxic Exposure, Thomas P. Byrne

Dissertations

In two experiments, the effects of MDMA were examined on the acquisition of lever-press responding by rats exposed to procedures in which water delivery was delayed by 0, 10, or 20 seconds. In the first experiment, naive, water-deprived rats received an intraperitoneal injection of MDMA (0, 1.0, 3.2, or 5.6 mg/kg) prior to one experimental session. Response acquisition was observed under all conditions at all drug doses. MDMA increased both response rates and reinforcers earned in a dose-dependent fashion, but only when reinforcement was immediate. Under conditions of delay, MDMA had no effect on the number of lever presses emitted …

A Computer/Tutorial System Compared With A Workbook/Tutorial Systeg For Presenting Instructional Material To At-Risk Elementary School Students, Vincent O. Hodge

Dissertations

Two different ways of presenting instructional material and reacting to students’ responses were compared. One, taking advantage of several features of multimedia instruction involved a desktop computer and various computer-presented consequences of correct and incorrect responses (largely chosen by the student). The other consisted in presenting the same instructional materials (the SRA primary curriculum) in a workbook form with tutors' comments and praise as the main form of response consequence. The two methods were compared with respect to various measures of student and system performance, including student accuracy (percent correct responses), types of errors, amount of correct response repetition (over-responding), …

Adolescent Perceptions Of Risk-Taking Behaviors, Susan Matthews

Masters Theses & Specialist Projects

Adolescents often make adult decisions regarding their lifestyle and behavior with little support from their family and community. In this study the researcher examined the difference in risk-taking behaviors between genders and the role that families and communities play in reducing risk-taking behaviors. In the study I further analyzed self-reports of numbers of development assets those students reporting participation in high-risk behaviors. Method: Data were obtained from a sample of convenience of (N=82) 12^th grade students. Behaviors and attitudes were examined using the Search Institute’s Profiles of Student Life survey. Results: Chi square was used to test for significant …

Disruption Of The Discriminative Stimulus Effects Of (+)-3, 4-Methylenedioxymethamphetamine (Mdma) By (± )-Mdma Neurotoxicity: Protection By Fluoxetine, Thomas B. Virden Iii

Dissertations

It is well established that repeated, high doses of 3, 4-methylenedioxymethamphetamine (MDMA) result in the long-term depletion of serotonin levels and destruction of serotonergic terminals in various locations in the brains of a variety of species. Further, it is also well known that concomitant injections of the serotonin reuptake inhibitor, fluoxetine, prevents this deterioration. It has recently been noted that such MDMA neurotoxicity disrupts stimulus control in rats trained to discriminate MDMA from saline in a drug discrimination procedure (Schechter, 1991a).

In order to extend Schechter's findings to the optical isomers of MDMA and to explore the potential of fluoxetine …

Mechanism Of Triazolo-Benzodiazepine And Benzodiazepine Action In Anxiety And Depression: Behavioral Studies With Concomitant In Vivo Ca1 Hippocampal Norepinephrine And Serotonin Release Detection In The Behaving Animal, Patricia A. Broderick, Omotola Hope, Pierrot Jeannot

Publications and Research

1. Real time, in vivo microvoltammetric studies were performed, using miniature carbon-based sensors, to concurrently detect norepinephrine (NE) release and serotonin (5-HT) release, in 2 separate electrochemical signals, within CA₁ region of hippocampus in the freely moving and behaving, male, Sprague Dawley laboratory rat.

2. Concurrently, four parameters of open-field Behavior I.E. Ambulations, Rearing, Fine Movements and Central Ambulatory behavior (a measure of anxiety reduction behavior), were assayed by infrared photobeam detection.

3. Time course studies showed that the mechanism of action of the triazolobenzodiazepine (TBZD), adinazolam, (Deracyn®) is dramatically different from that of the classical benzodiazepine (BZD), diazepam …

The Clinical Utility Of The Jesness Inventory, Stephanie J. Hayes-Harris

Theses, Dissertations and Capstones

Because previous research findings on the Jesness Inventory have been relatively inconsistent, the current study was conducted to further examine this instrument's reliability, convergent validity and classificatory ability. A 3 to 11 month test-retest interval used with 42 adjudicated adolescents yielded a mean correlation coefficient of .60 and suggested that the stability of the 11 individual subscales is questionable. Using 42 adjudicated adolescents and 48 outpatients, many significant correlations were obtained between the Jesness Inventory and the Adolescent Multiphasic Personality Inventory subscales. Similarly, the Asocial Index accurately classified the adjudicated adolescents as delinquent and the outpatient adolescents as nondelinquent, as …

Concurrent Validity Of The Mattis Dementia Rating Scale, Kathryn L. Ingles

Theses, Dissertations and Capstones

The Dementia Rating Scale (DRS) is a brief, comprehensive screening instrument for neurological impairment. The DRS has a low floor and enables progressive levels of dementia to be measured. The purpose of this study was to evaluate the concurrent validity of the DRS. Eighteen subjects from nursing homes and personal care homes diagnosed with mild to moderate Dementia of the Alzheimer’s Type were involved in the research. The score on the DRS was correlated with the raw scores on the Block Design and Vocabulary subtests of the WAIS-III. Research indicates that the performance on the Block Design subtest is a …

Conduct Disorder Questionnaire, Dwayne L. Milam

Theses, Dissertations and Capstones

Conduct disorder is characterized by a pattern of rule violation in which the rights of those associated with the individual and society are violated. Frequently there are many problems at home, school, and within the community. Without early diagnosis and treatment these problems escalate. Many different techniques and assessment tools have been used to identify these individuals. Most rely on collateral informants, such as parents and teachers. Others are time consuming or not developed to specifically identify conduct disorder. The Conduct Disorder Questionnaire was developed by the author to address these issues. The questionnaire is a brief, easily scored self-report …

Chi Square Analysis Of The Supported Employment And Unsuccessful Placement Survey To Assess Individualized Needs When Program Planning, Melissa S. Nelson

Theses, Dissertations and Capstones

This study is a chi square analysis of the Supported Employment Survey (SES) and the Unsuccessful Placement Survey (UPS) developed for the purpose of this study. Subjects included 76 males and 35 females ranging from the ages of 19 to 64. All of the individuals included in this survey have been involved in supported employment programs throughout the state of West Virginia. Individuals were surveyed based on DSM-IV diagnosed disability (mental retardation verses mental illness), support networks during placement (living independently or with a family member), and previous experience in sheltered workshops prior to placement in support employment programs. Results …
