The Efficacy Of Eye Movement Desensitization In The Treatment Of Trauma Related Imagery And Cognitions: A Partial Dismantling Procedure, George S. Renfrey

Dissertations

This study investigated the effects of eye movement desensitization (EMD) on post-traumatic sequelae, and attempted a partial dismantling of the procedure to determine the necessity of EMD's characteristic eye movements. Twenty-three persons participated in three groups: (1) those receiving standard EMD, (2) those receiving a variant of EMD in which eye movements were engendered through a light tracking task, and (3) those receiving a variant of EMD in which fixed visual attention replaced eye movements. All participants had experienced traumata as defined by the DSM-III-R and were having intrusive symptoms of PTSD at pre-treatment. All but two met full DSM-II-R …

The Acute Effects Of Cocaine In Pigeons Performing Under A Progressive-Ratio Schedule, Claudia Ann Jones

Masters Theses

Although the progressive-ratio (PR) schedule has been used frequently to quantify the reinforcing effectiveness of self-administered drugs, it has seldom been used to examine the effects of drugs on food-maintained behavior and has never been used to evaluate the effects of cocaine on such behavior. In the present study, the effects of acute administrations of cocaine were evaluated in pigeons responding under a PR schedule of food delivery. Overall, cocaine produced a dose-dependent effect on food-maintained behavior. In general, acute administrations of cocaine at 0.56 to 3.2 mg/kg increased breaking points, whereas doses above 5.6 mg/kg decreased breaking points. Low …

Computer-Based Fluency Training With The Terminology Of Behavior Analysis, Guillermo E. Yaber-Oltra

Dissertations

This study examined the effects of computer-based fluency training on the learning of behavior-analysis terminology. Sixty-nine undergraduates studied the definitions of half a set of behavior-analysis terms using a computer program Think Fast (Parsons, 1989), and half using their regular methods. Think Fast training items consisted of typing the words missing from definitions. On seven out of nine post-training quizzes, students were better able to define terms previously studied with the computer program. In a related experiment, volunteers studied half a new set of terms using the computer, either typing or saying the answers. Students mastered the definitions better when …

Failure Of Methamphetamine Withdrawal To Produce Behavioral Disruptions In Pigeons, William F. Potter

Masters Theses

Methamphetamine, a widely used recreational drug, is not known to produce physiological dependence. Few studies to date have examined whether behavioral dependence occurs upon sudden withdrawal from methamphetamine. In this study, pigeons (n=4) were trained to respond under a multiple FR 25 IRT > 6-s schedule of reinforcement, allowing for examination of drug effects upon a relatively high rate of responding (FR) and a relatively low rate of responding (IRT > t). Acute adminstrations of methamphetamine showed rate-dependent effects at low doses, while higher doses decreased responding under both schedules. Tolerance was demonstrated for all subjects except one at the highest dose …

Spanish Translation And Validation Of The Daily Stress Inventory, And A Comparison Of The Level Of Stress Experienced By Three Culturally Distinct Hispanic Groups, Senez Rodriguez-Charbonier

Dissertations

High levels of stress in the general population have been found to correlate both with psychological and physical illness. The fast growing Hispanic population in the U.S. is exposed to increased levels of stress associated with a number of situations (e.g., language barriers, and socioeconomic status). There are, however, no validated stress measures applicable to the Hispanic community as a whole.

The purpose of this study was twofold: First, to translate into Spanish the Daily Stress Inventory (DSI) (Brantley & Jones, 1989) and to validate the translation by conducting a correlation study between the the Spanish and the English versions. …

The Effects Of Differing Response Force Requirements On Response Rate And Post-Reinforcement Pause, Kenneth Lee Ailing

Dissertations

The present study consisted of three experiments in which rats were exposed to two-component multiple schedules of reinforcement. In the first experiment, fifteen responses were required to produce reinforcement in both components of the multiple schedule. In one component 25 g of downward force was always required to operate the response lever. In the other, the force required varied from 25 g to 200 g across conditions. In the second experiment, fifteen responses were required to produce reinforcement in both components of the multiple schedule. In one component 25 g of downward force was always required to operate the response …

The Vocational Interests Of Prisoners: A Preliminary Validation Study Of The Lustig Color Vector Test, Hanoch Livneh, Robert E. Pullo, Paul Lustig

Counselor Education Faculty Publications and Presentations

The purpose of this study was to provide empirical evidence for the validity of the Lustig Color Vector Test (LCVT) as a vocational interest measure. The LCVT, a nonverbal instrument, is a schematic attempt to represent the Vector Theory of Behavior which describes human behavior in terms of motion and the laws of physics. A sample of 92 participants was chosen to represent the literate male population of incarcerated offenders in the Wisconsin state prison system.-Participants were administered the LCVT as well as Holland's Vocational Preference Inventory (VPI) and a demographic questionnaire. The results offered tentative support to the notion …
