Variations In A Color-Line Aftereffect Due To Color Adaptation During Inspection Of The Inducing Stimuli, Joyce Hirsch

Dissertations and Theses

The McCollough Effect is an orientation specific colored aftereffect. That is, following prolonged viewing of a vertical grid on orange ground alternated with a horizontal grid on blue ground, a yellow-orange hue is perceived on an achromatic horizontal grid, and a bluish hue on a vertical grid. McCollough suggested that the colored aftereffect may depend upon color adaptation of a population of neural elements specific to colored edges of a particular orientation. Accordingly vertical edge detectors sensitive to orange adapt during inspection such that when vertical edges are presented on an achromatic ground only those non-adapted color-line detectors respond creating …

The Effects Of Marihuana Extract Distillate On Eating Behavior Of Rats, Terrie Wetle

Dissertations and Theses

Since hunger drive is often used as a motivating factor in animal learning experimentation, it was decided to determine the effects of marihuana extract distillate on the eating behavior of rats. Carlini and Kramer (1965) found marihuana extract injections to have a faciliatory effect upon maze performance. They suggested that facilitation could have resulted from and increase in hunger drive. However, if the dosage level is high, this effect may last for a short time and be followed by a disinterest in food. Scheckel et al. (1968) report that some monkeys, at very high dosage levels of tetrahydrocannabinol starved to …

Age, Emotional Maturity And The Decision To Marry, Patricia Ann Duclos, David F. Thomas, Joanne Zusman

Dissertations and Theses

The decision to marry and choice of mate are two issues contemplated by most individuals during their lifetime. It is our belief that the manner in which an individual makes these decisions is a reflection of that individual’s level of emotional maturity.

In our society, the right to enter into a marriage agreement is largely determined by chronological age. Our research problem began with the hypothesis that there is no direct relationship between chronological age and emotional maturity at the time of marriage.

For our study, marriages were divided into two general categories: 1) teenage marriages in which at least …

An Interactional Approach To Weight Reduction, Carole T. Gygi

Dissertations and Theses

A treatment program was designed to enable subjects to lose weight through the use of self-confrontation as described in Saslow (1969), and the use of the General Relationship Improvement of the Human Development Institute (HDI), Berlin and Wyckoff (1964).

Self-confrontation is a programmed rehearsal of a specific problem by one person alone, for a five-minute period. The rehearsal, or self-confrontation is to be as vivid as possible, intellectually, emotionally, visually and physically.

The General Relationship Improvement Program is a 10-week text, worked in pairs, which is aimed at better intrapsychic and interpersonal communication and understanding.

Four matched groups were used …

The Structuring Of Procedures Utilized In An Adult Stuttering Treatment Program, Sarah Jane Prichard

Dissertations and Theses

In recent years, operant conditioning techniques have been effectively used to modify a variety of behaviors. For the most part, the modification of stuttering behavior has relied solely on the use of punishment. The shaping of "fluency” through differential reinforcement has been reported as a behavioral approach for the treatment of stuttering; however, the effectiveness of this technique in combination with other "teaching" tools, such as, modeling, instruction, and explanation has not been reported in the literature.

The purpose of this study was to construct behavioral definitions of terminology utilized in a stuttering treatment program at Portland State University to …

Teaching Social Studies From A Global Viewpoint, Janet Hays Clemmer

Dissertations and Theses

The need for preparing our youth to live in an interdependent world on this finite planet has become urgent since the beginning of the nuclear age at the end of World War II. There is a need to extend the loyalty of the citizen tor the nation-state to human needs seen from a global view. The involvement of the United States in the international community already is extensive because of its predominant power. This involvement is not reflected in our education, either from the amount of time devoted to social studies in our schools or in the emphasis on international …

Schedule Interactions And Stimulus Control, Andrew Louis Homer

Dissertations and Theses

Four types of schedule interactions have been defined: positive contrast, negative contrast, positive induction, and negative induction. Most work has centered on the necessary conditions for positive contrast. One position states that a reduction in reinforcement frequency is necessary; the other view states that a reduction in response rate is necessary. Neither view can account for the occurrence of induction. The present experiment tests the hypothesis that stimulus control effects the occurrence of either contrast or induction. Three pigeons were trained to respond for primary reinforcement (strong stimulus control condition), and three pigeons were trained to respond for conditioned reinforcement …
