Behavioral Toxicology Of A Glucocorticoid: Analysis Of Selected Behavioral And Physiological Effects Of Repeated Prednisolone Treatment, Robert G. Sewell

Dissertations

Glucocorticoids are used medicinally for numerous chronic ailments. While dramatically effective, glucocorticoid treatment is replete with psychiatric complications. The behavioral toxicology of glucocorticoids, however, remains relatively unexplored. Therefore, 13 laboratory studies were performed to analyze the influence of prednisolone, a representative glucocorticoid, upon varied behavioral and physiological endpoints in rats. Experiments 1-3 showed prednisolone to produce marked hypodipsia, body weight loss, selective adrenal gland atrophy, hyperactivity, hyperalgesia, altered grasping responses, hyperglycemia, enhanced predation, and conditioned taste aversion. Most of these findings were directly dependent upon dose, and where explored, number of treatments. The remaining ten studies examined both acute and …

Reinforcement Increases The Strength Of An Elicited Response, Michael D. Peters

Dissertations

A response initially produced by noncontigent fixed-time delivery of brief electric shock was strengthened by reinforcement. Following the fixed-time shock baseline condition, response contingent shock absence (avoidance) was programmed for the lower probability of two response options for one group of squirrel monkeys. For the other group the interposed history was variable-interval food reinforcement. When responding was reliably maintained reinforcement was discontinued and a return made to fixed-time shock conditions as programmed prior to reinforcement. Upon a return to original conditions, rates were substantially elevated over baseline with the elevation sustained for many sessions. The avoidance group showed the most …

The Effects Of Reward And Reinforcement On Intrinsic Interest, Alyce Muzette Dickinson

Dissertations

Under certain circumstances, rewarding individuals for performing a task that they enjoy may decrease their subsequent interest in that activity when rewards are no longer available. Decreased task interest is not, however, an inevitable outcome of reward and the subsequent termination of reward. This study investigated one variable that may influence whether task interest will increase or decrease following reward termination: the degree to which the reward is reinforcing. The study also examined how long post-reward performance changes persisted when they occurred.

A multiple-trial, within-subject comparison design was employed in which three reward phases were alternated with post-reward phases. Two …

The Use Of An Incentive System To Increase Worker Performance In A Financial Setting, Steven S. Armstrong

Dissertations

The use of merchandise as a consequence in a performance based incentive system was assessed in a financial setting. Points were earned by each subject based on individual daily performance. These points were collected by each subject and used toward the purchase of merchandise. A multiple baseline across two groups of bank tellers showed substantial increases in worker behavior after the onset of contingent points. Differences between groups existed and an analysis is provided. Follow-up data revealed sustained performance and a cost-benefit analysis demonstrated substantial savings.

The Effect Of Medicaid Billing On Service To Developmentally Disabled Adults, Kambiz Alavi

Dissertations

This study provides a detailed analysis of the daily service delivery records before and after the introduction of a Medicaid Billing Form at a day-activity center for developmentally disabled adults. The form required therapists to record daily service delivery (in 15-minute units) to Medicaid eligible clients. There were 38 clients, 23 Medicaid and 15 non-Medicaid, and four therapists. The data showed, for three of the four therapists, a clear and large increase in reported service delivery to Medicaid clients and a smaller increase to non-Medicaid clients. Six months after the introduction of the Medicaid Billing Form the therapists were required …

The Feature-Value Effect In Children; An Attempt To Replicate And Further Experimentation, Kathleen Wright

Dissertations

In the "feature-value effect" faster acquisition occurs when a distinguishing feature is placed on the correct stimulus (S+) during discrimination training than when the distinguishing feature is placed on the incorrect stimulus (S-). The former is a "feature positive" discrimination task, whereas the latter is a "feature negative" discrimination task. The feature-value effect only occurs when the discrimination involves stimuli that are identical except for one distinguishing feature. The effect has been obtained in a number of nonhuman species as well as in children and adult humans. Experiments 1 and 2 failed to replicate the findings of previous experiments with …

Peer Influence: A Method To Help Manage Stress, Ronald Cameron Zurcher

Dissertations

Purpose: The purpose of this project was to find a difference between middle managers’ and blue-collar workers’ episodic non-work related and work related stress events. The information that was found was to be developed into a “peer influence” program to help prevent the workers from experiencing chronic stress symptoms.

Method: From research it was determined that there is a significant difference between middle managers’ and blue-collar workers’ episodic non-work and work related stress events. The material that was reviewed showed a difference in five areas: threat of job loss, lack of authority, new social values (sociability), personal life (satisfaction), and …

An Integrative Model Of Marital Therapy Based On The Psychoanalytic Behavioral And Systems Approaches, Dennis L. Mulder

Dissertations

The Integrative Model of marital therapy is a synthesis of the theoretical constructs of the psychoanalytic, behavioral and systems approaches. Relevant literature of the selected approaches is reviewed. The concepts of marriage, marital conflict and marital therapy of each approach are described. The Integrative Model is based on three assumptions and six propositions. The Integrative Model attempts to interpret the intrapsychic dynamics of intimate relationships in a data language suitable for empirical study. It attempts to define the relationship between internal and external determinants of behavior. It proposes a method of intervention consistent with the cognitive/behavioral conceptual model and procedures …

Effects Of Reinforcement Duration And Reinforcement On Response Latency: Stimulus-Reinforcer And Probability Response-Reinforcer Relationships, Henry David Schlinger Jr.

Dissertations

The purpose of the present experiment was to evaluate the stimulus-reinforcer and response-reinforcer relationships in a two-key procedure in which the key that the stimuli appeared on (stimulus key) was separated spatially from the key on which responding was required (constant key) (Hesse, 1984; Keller, 1974). Using pigeons and multiple fixed ratio schedules, the effects of differences in reinforcement duration and reinforcement probability on response latencies to the constant key were compared. Since responding to the stimulus key was not effective in producing reinforcement, any responding that developed to that key was assumed to be due to the stimulus-reinforcer relationships. …

Occupational Identity Assessment Among Middle And Late Adolescents, Julian Melgosa

Dissertations

Problem. Research on James Marcia's identity statuses has been directed toward the overall problem of identity, but not toward the specific area of occupational identity. The major purpose of this study was to develop and validate an instrument to assess Marcia1s Identity Statuses (Achievement, Moratorium, Foreclosure, and Diffusion) for the occupational area. In addition, the relationships of selected variables to these statuses were investigated.

Method. Random class groups of students (N=417) from six selected high schools and colleges located in Michigan provided the data for this study. Items were created utilizing the criteria established by previous research and content validated …
