The Effectiveness Of Environmental Control In Modifying Problem Behaviors In Mother-Child Interaction, Thomas Whalen Hamilton

Dissertations and Theses

An experiment was designed to test the effectiveness of using standard laboratory environments in producing a broad class of problem behaviors which defined Mother-Child (M-C) interaction difficulties. The effects of four environments, free-time (X), child's game and rules (B), mother's game and rules (C), and clean-up (Z), on the frequency of eight criteria behaviors were tested on 12 M-C pairs over three days of baseline data collection. It was predicted that the frequency of problem behaviors would decrease as a function of environment (X) and increase as a function of environments (B), (C), and (Z). A two factor …

Behavioral Changes Due To Overpopulation In Mice, James Robert Hammock

Dissertations and Theses

Previous research has found that if a population were allowed to exceed a comfortable density level, then many catastrophic events occurred such as increased mortality among the young, cannibalism, homosexuality, and lack of maternal functions. The most influential researcher in this area is Calhoun (1962), after whose experimental design a pilot study was fashioned to replicate his results. The results of this pilot study inspired a more detailed research project of which this thesis is an account.

Forty-eight albino mice of the Swiss Webster strain were divided into three groups of sixteen each. Each group consisted of ten females and …

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 …

Action-Oriented Group Therapy For Lower-Socio-Economic-Status Clients, Joan C. Peters

Dissertations and Theses

An attempt is made to present a model of group therapy for Lower-Socio-Economic-Status (LSES) clients. The theoretical issues include a definition of traditional group therapy along with a brief description of the more recent sensitivity training approaches. A rationale for combining these two different group approaches is presented to form the model for action-oriented group therapy (ACT groups) which utilizes both the traditional approach and action techniques of the sensitivity group. It is proposed that this hybrid, the AOT group, is more appropriate for treating the LSES client. The needs and expectations of the LSES client are discussed. The goals …

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 …
