Sequences Of Fixed-Ratio Schedules Of Reinforcement: The Effect Of Ratio Size In The Second And Third Fixed-Ratio On Pigeons' Choice, Susan Goeters

Dissertations

The present study used a discrete-trials procedure to examine choice in pigeons presented with various three-component sequences of fixed-ratio schedules of reinforcement. An experimenter-controlled stimulus was correlated with each sequence and pigeons were presented with a specified number of forced-exposure and choice trials. Three phases were implemented in an effort to investigate the conditions under which fixed-ratios other than the first in a sequence of three affect choice. In Phase 1, pigeons were given a choice between a fixed-ratio X fixed-ratio 1 fixed-ratio 25 and a fixed-ratio X fixed-ratio 25 fixed-ratio 1 sequence of food delivery. Across conditions, X was …

The Effects Of Individual Feedback And Group Feedback On The Nominal Group Technique, Monica Porter

Dissertations

The nominal group technique (NGT) was modified and implemented in an educational setting. Procedures included (a) targeting and voting on the most important issue, (b) generating a list of possible solutions and providing rationales, and (c) completing a final report as a group consensus.

The effects of individual feedback and group feedback on the NGT were examined. Group 1 received individual feedback followed by group feedback, and Group 2 received group feedback followed by individual feedback.

Twenty undergraduates served as subjects and participated in problem solving tasks in which individual feedback and group feedback were provided on the subjects' written …

The Effects Of Relaxation Plus Imaginal Flooding Versus Relaxation Only On Panic Attacks In Veterans With Post-Traumatic Stress Disorder, Jan E . Bachman

Dissertations

Many Vietnam veterans experience intrusive recollections of combat-related events in the form of nightmares and flashbacks, a primary symptom of Post-traumatic Stress Disorder (PTSD). Imaginai flooding has shown some promise in reducing the frequency and intensity of these. Cognitive- behavioral therapies have also been used, but their effectiveness has not been studied. Experiment 1 attempted to determine whether a self-imposed version of imaginai flooding (called Self-Imaginai Flooding) could be used rather than the usual therapist-led procedure, and whether treatment effects could generalize from the treated to untreated intrusive memories. In a between groups design, with six Vietnam veteran subjects in …

Organizational Development Through The Implementation Of Strategic Plans, Susan M. Eickhoff

Dissertations

Organizations today need effective and efficient total organizational change strategies in order to ensure both short- and long-term organizational health. As a result of an organization being a multi-dimensional entity, the ingredients for its change strategy must necessarily be representative of all its dimensions such as business management, information system, behavior analysis, behavioral systems analysis, total quality management and statistical process control techniques. Those ingredients of a comprehensive change strategy exist but have not been put together into a totally integrated package so far. In the present study, a fully-integrated organizational change strategy was systematically employed with the goal of …

Acquisition Of Conflict Management Skills With High School Adolescent Females, Leslie Skinner-Hughes

Dissertations

This study examined the effects of a conflict management training program on the performance levels of high school adolescent females. Twenty female adolescent students were randomly assigned in equal numbers to either an experimental or control group. The students in the experimental group participated in a one school-day training program in conflict management skills. The students in the control group participated in two hours of discussion on handling conflicts. Pre- and post-training performance was measured by videotape recordings, classroom behavior ratings, behavior checklist, and student records of referrals for discipline.

The results showed the following: (1) The videotapes revealed a …

Effects Of Interactive And Linear Video On Patient Understanding Of Risks In Medical Procedures, Christopher P. Giuliano

Dissertations

Three methods of providing information relevant to informed consent where a vaginal birth after cesarean section was being considered were evaluated; (1) the traditional and common method (physician presentation), (2) Linear Video Tape (LVT), and (3) Interactive Video Disc (IVD). The traditional and common method of presenting information led to only limited acquisition of knowledge resulting in patients making less than fully-informed decisions. Both the linear video tape and the interactive video disc led to significantly greater understanding of the risks and benefits of the procedure than did the physician presentation. The interactive disc and the linear video tape were …

A Parent Training Program For Teaching Preschool Children Independent Self-Care Skills, Dalene Rooks Degraaf

Dissertations

Teaching children to be independent is a challenge for parents. Initially, parents directly prompt and consequate their children’s behavior. Later, the parents fade prompts and delay consequences expecting their children to use self-management skills and environmental cues to complete tasks. The purpose of this study was to observe some of the methods which parents use to teach their 4-year-old children independent self-care skills and test the effects of a parent training program. The program was designed to transfer stimulus control from the parent’s physical or verbal prompts to textual and picture prompts on a poster listing the morning self-care skills …

Ease Of Learning And The Emergence Of Equivalence Class Formation: A Comparison Of Topography-Based And Selection-Based Paradigms, Riad M. Wraikat

Dissertations

Michael (1985) identified two types of verbal behavior, topography-based (i.e., speaking or using sign language) and selection-based (i.e., symbol board). Sundberg & Sundberg (1990) and Wraikat (1991) compared these systems in terms of the ease of learning object naming (tact) and giving the correct sign or pointing to the correct symbol on hearing the object name (intraverbal). Sundberg & Sundberg (1990) also compared them for the spontaneous development of a new relation, identifying the object when hearing its name (stimulus class formation or equivalence). The results of both studies favored the topography-based system, but in each case some subjects were …

Effects Of Differential Force Requirements On Choice Behavior Under Concurrent-Chain Schedules, Randal D. Reynolds

Dissertations

Concurrent-chain research shows that choice behavior is sensitive to differential delays to reinforcement but apparently insensitive to differential response-requirement factors. To date, however, no studies have directly investigated the effects of differential force requirements on choice behavior under concurrent-chain schedules. This relationship will be the focus of the present study.

In Experiment 1 rats responded on conventional concurrent-chain schedules and were given a choice between different terminal-link force requirements. The force requirement on one terminal-link lever was 0.25 N while the force requirement on the other lever was varied from 0.25 N to 1.51 N across conditions. For comparative purposes, …

The Effects Of Methylphenidate On The Repeated Acquisition Performance Of Children With Attention Deficit Disorder, Christopher P. Giuliano

Dissertations

The effects of methylphenidate on the repeated acquisition performance of three children between the ages of 9 and 13 were examined. The repeated acquisition task was programmed on a micro computer and daily doses of 0.6 mg/kg and 1.0 mg/kg of methylphenidate were compared with an active placebo (caffeine). There was no discernible effect for two of the subjects. One subject showed only a very slight facilitative effect at the 1.0 mg/kg dose, using trials-to-criterion as the dependent measure. Methylphenidate had no effect on errors or rate of responding for any of the subjects. Teacher ratings of behavior indicated improvement …

Contrived Versus Natural Reinforcers In The Acquisition Of A Verbal Repertoire By Adult Learners, Lisa Ann Leblanc

Dissertations

Previous research suggests that by making classroom contingencies for verbal responding more like those in the natural environment, i.e., by using motivative variables to evoke verbal responses which are followed by specific actions on the part of listeners, verbal repertoires can be taught more effectively to children and language impaired individuals. The present study examines the role of specific versus generalized conditioned reinforcement following adult students' question-asking on the acquisition of a verbal repertoire in a classroom setting and on the generalization of this repertoire to a more natural verbal environment.

Subjects were 32 university students in two American Sign …

Effects Of Training Method On Inspector Accuracy In A Simulated Quality Control Task, Cathy L. Thorne

Dissertations

This study compared the effects of three training programs on inspector accuracy. The inspection task required 38 subjects to detect errors in geometric figures. All three training programs provided the same written descriptions of correct and incorrect figures, and all three training programs provided examples of correct figures. What differed among the programs was the type of incorrect figures. Individuals assigned to the Correct Sample Only Group were not shown any incorrect figures. Individuals assigned to the Critical Differences Group were shown incorrect figures which contained only one error at a time. Individuals assigned to the Multiple Differences Group were …

The Training Of Initial Behavioral Assessment Interview Skills, Mark J. Hirsch

Dissertations

Two manuals were used to train behavioral assessment interview skills. The first manual outlined eleven initial responses the therapist must make to determine the controlling variables related to a client’s problem. The second manual outlined strategies for dealing with evasive or nonappropriate responses made by a client. Subjects were graduate students from the psychology department of Western Michigan University who had no experience in conducting assessment interviews. Six subjects participated. Simulated therapy sessions between subjects acting as therapists and confederates acting as clients were conducted. Scripts were utilized to standardize confederate responses. Each session dealt with a clinical concern amenable …

A Comparison Of Three Procedures For The Establishment Of A Novel Response With Delayed Reinforcement, Jayson W. Wilkenfield

Dissertations

The purpose of the present study was to compare three procedures for examining the degree to which delayed response-dependent presentations of food would result in the acquisition of lever-pressing in rats. Although there is an abundance of research examining the maintenance of behavior with delayed reinforcement, few studies have investigated reinforcement delays in the acquisition of new discrete behaviors. Historically two different procedures have been employed in the study of delayed reinforcement. In a nonresetting delay procedure a response sets up the delivery of a reinforcer to occur after t seconds, and responses that may occur during the delay interval …

Choice By Rats For Enriched Versus Standard Home Cages Plastic Pipes, Wood Platforms, Wood Chips, And Paper Towels As Enrichment Items, Anita Lynn Bradshaw

Dissertations

The purpose of the present study was to determine whether simple additions to the home cages of rats made those cages preferable to standard housing arrangements. Results indicated that the majority of rats preferred cages with wood platforms, wood chips, and paper towels to otherwise identical cages without these items. Wood chips were not, however, practical with the cages used in the present study. Plastic pipes caused no problems but were not preferred by the majority of individual animals. Both wood platforms and paper towels created no problems and appeared to be useful as enrichment items. The latter were preferred …
