Use Of A Supervisory Safety Checklist And Safety Meetings To Reduce And Prevent Hazardous Safety Conditions In An Automotive Plant, Todd Alan Brighton

Masters Theses

Hazardous safety conditions and incidents were operationally defined for an assembly division at an automotive plant. The conditions were observed and recorded on two different employee shifts for an 11 week period. The experimental design used had three distinct phases. In the first phase baseline data were recorded on the number of hazardous safety conditions by two safety observers. In the second phase two shift supervisors used the safety checklist to record hazardous safety conditions. In the last phase data were taken but the supervisory safety checklist was not used. The data from all observations were discussed in safety meetings …

The Use Of Job Aids As An Alternative To Training New Employees, William D. Powers

Masters Theses

Lack of knowledge required to perform a job, has often been dealt with by implementing some sort of training program. However, some businesses cannot afford to implement training. This study tested the effectiveness of using job aides as an alternative to training two new employees at a small business which had no training program. Step-by-step instructional aids were developed for rebuilding Series 40 MT Delco starters and Series 10 SI Delco alternators. A multiple-base-line between subjects design, with an ABABAB reversal, was used.

The data showed the average time required by the new employees to rebuild Series 40 MT Delco …

Applied Undergraduate Training In Psychology And Career Choice, Nancy S. Hinga-Wright

Masters Theses

The present investigation evaluated the relation between additional undergraduate practical training in psychology (other than standard course credit) and the graduate school or career choice of graduates with a bachelor's degree in psychology. Based on data from questionnaires and university student records, the results indicated a positive, significant relation between graduate school choice and subsequent career choice, although there was no significant relation between additional applied training and career choice. The results also showed no significant relation between grade point average and career choice, and sex and career choice. The conclusions suggested several outside variables that may influence students' decisions …

The Effect Of Word Abbreviation On Decoding Speed And Accuracy, Frances Piccione

Masters Theses

An experiment was conducted to verify the existence and determine the magnitude of the human response latency differential between words and their abbreviations in a decoding task. Forty-eight Naval Officer Candidates learned a set of abbreviations obtained from operational aircraft cockpits. Abbreviations and corresponding words were divided into easy and hard difficulty levels. Subjects responded by saying the correct whole-word for both stimulus types. Response times measured by a voice key revealed a mean of 0.534 seconds for words and 0.662 seconds for abbreviations. An analysis of variance produced significant main effects (p < .05) for stimulus types and difficulty levels; the interaction effect was not significant. Also, t-tests for correlated scores revealed significant differences (p < .05) between difficulty levels within stimulus types.

Effect Of Fixed-Ratio Size On Response-Latencies Produced By Other Variables, Albert Edward Neal

Masters Theses

Using a discrete-trial, two-component multiple schedule, pigeons were required to complete a fixed-ratio in the presence of stimuli correlated with different probabilities of reinforcement (Experiment 1), or different amounts of reinforcement (Experiment 2). The amount of separation of graphed median latencies to the onset of the two stimulus conditions as a function of the different reinforcement conditions was investigated in relation to various fixed-ratio values. It was found that previous researchers had chosen an optimal fixedratio size; larger ratios produced greater separation between median latencies, but at the expense of increased session-to-session variability, while smaller ratios failed to produce median …

The Effects Of Teacher Directed Small Group Instruction On Quality And Control Of Behavioral Contracts In A Large Study Section Of High School Students, Laurie A. Thompson-Montgomery

Masters Theses

Individualized education has been described as the ideal teaching methodology. The purpose of the present study was to individualize teaching procedure through the use of behavioral contracts in a high school guided study class. The goal of the teacher-directed, small group instruction was to teach students the components of a specific contract task. Following this instruction, all students' contracts improved in the percent meeting content criteria. In addition to improvement in contract content, student on-task behavior also increased. Further, the number of student assignments completed on contract which were received by teachers increased after training. It appears that the use …

Validation And Validity Generalization Of Placement Exercises Used In The Selection Of Clerical Employees, Keith Edward Mitchell

Masters Theses

A follow-up study was conducted to determine the predictive validity of a group of job-related Placement Exercises used in the selection of clerical employees for a northeastern utility company. The present study was also to determine if the obtained validities could be generalized to similar organizational settings.

The subjects included in this study were 98 clerical employees working in the job classifications of Junior Clerk, Clerk, Intermediate Clerk, and Secretary-Stenographer. The obtained results supported the hypothesis that a positive and significant relationship existed between performance on the Placement Exercises and supervisory ratings of employee job performance. After applying the results …

The Effects Of Self-Evaluation Procedures On The Numbers And Accuracy Of Alphabet Letter Writing Behavior Of Preschool Children, Kevin R. Coleman

Masters Theses

This study assessed the effects of self-evaluation procedures on the rate and accuracy of alphabet letter writing. Three preschoolers served as subjects. During Phase I, students were given instructions, and the experimenter modeled accurate letter writing. During Phase II, instructions and modeling were again presented. Additionally, the students were given a rule statement that instructed them to use a stamper and a stamp pad to stamp their paper after first writing each of a row of four letters. The results indicated that the introduction of self-evaluation procedures was associated with immediate increases in frequency of attempts, but a decrease in …

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. …

The Effects Of Intermittent Photic Stimulation Upon Respiration Rate And Anxiety, Patricia Moulton Guilford

Masters Theses

An experiment was performed to examine the effects of the visual stimulus property of flicker on respiration rate and state-anxiety level. Forty undergraduate college student volunteers were randomly assigned to three groups which received intermittent photic stimulation (IPS) and a control group which did not receive IPS. Each IPS group received and the range of flicker frequencies, 4 cycles per second to 14 cycles per second, in a different pattern. All subjects were administered measures for trait-anxiety and changes in state-anxiety.

Results suggest that respiration rate positively covaries with the frequency of the intermittent visual stimulus within this range of …

The Effects Of Aspartame On Locomotion And Body Weight In Rats, Linda Dianne Dykema Larsen

Masters Theses

Nutrients, when ingested in isolation from other food stuffs or in excess, may produce drug-like action on neurotransmitter activity in the CNS. Administration of aspartame exclusively or in combination with d-amphetamine was found to produce weight loss and display of emotionality in rats as measured in an open field apparatus. The possible neurochemical action of aspartame was discussed relative to the well documented stimulatory effects on catecholamines of d-amphetamine and three putative mechanisms were explored: 1) formation of minor amines from the increased precursor pool, 2) increased synthesis of catecholamines in response to the increased precursor pool, and 3) decrease …

Computer-Assisted Consultation: Problem-Identification, David B. Lennox

Dissertations

Three experiments were conducted to validate the effectiveness of Computer-Assisted Consultation (CAC)--a computer-based problem identification interviewing system for use in conducting school-based behavioral consultation. The specific goals of problem identification are to establish behavioral objectives and initial assessment characteristics. Experiment I functioned as a pilot which: (1) validated the need for problem identification, (2) demonstrated the general utility of CAC, and (3) provide a basis for program improvement. Experiment II provided a more rigorous analysis of CAC by comparing it with an actual problem identification interview. Two groups of three consultees each were exposed to one of two counter-balanced sequences …

The Effect Of Aerobic Training And Weight Training On The Cardiorespiratory Fitness, Body Cathexis, And Self-Concept Of College Females, John Stuart Irvine

Dissertations

The present study investigated the effects of two differing exercise programs, aerobic training and weight training, upon the body cathexis, global self-concept, and cardiorespiratory fitness of college females. The subjects were undergraduate nonintercollegiate athletes who self-selected into four different physical education classes that served as the two experimental and one control group. The subjects in the aerobics exercise group engaged in rope jumping, aerobic dance, and jogging for 50 minutes, twice per week, for 14 weeks. The weight training experimental group utilized free weights and variable resistence strength training equipment during the 14-week, twice weekly, 50-minute sessions. The control group …

Feminine Role Orientation And Locus Of Control In Battered Women, Nancy C. Zielke

Dissertations

The purpose of this study was to examine locus of control and feminine role orientation in battered women. It was hypothesized that battered women would have a more "external" locus of control than women who have not been in a battering relationship. It was also hypothesized that battered women would describe themselves as having more characteristics that are traditionally associated as "feminine" in nature and fewer characteristics that are considered "masculine" in nature than women who have not been in a battering relationship. Finally, it was hypothesized that there would be a relationship between locus of control and self-perceived feminine …

Thirty-four undergraduate students on academic probation were referred to the Center for the Self-Management of Academic Performance by the College of Arts and Sciences. These students were divided into two groups: an experimental group which consisted of 21 students and a control group which consisted of 13 students. Members of the experimental group were exposed to a treatment package which included behavioral contracting, lectures, and mandatory attendance at a study center; members of the control group …

Methylphenidate Effects On The Learning And Performance Of Four Hyper Active Children, Paul James Yoder

Dissertations

The effects of methylphenidate hydrochloride (Ritalin) on the learning and performance of four hyperactive children were evaluated using a repeated acquisition procedure with both learning and performance components. Three dosages of methylphenidate plus a placebo were evaluated under double-blind experimental conditions. Dosages treated included each subject's therapeutic dosage, a dosage 5 milligrams higher, and a dosage 5 milligrams lower. Methylphenidate produced no effect on either the number of errors per session or on the rate of responding across the range of dosages tested suggesting that the medication neither facilitated nor impaired learning or performance. Data were also collected on social …

Using Performance-Management To Improve The Academic Success Of High-Risk College Students, Valerie L. Jager

Masters Theses

This study evaluated the effectiveness of a performance management program designed to improve the academic success of high-risk college students; students who had been previously dismissed from the university and had grade point averages (GPA) below 2.0 (on a 4.0- point scale). Twenty-two of these high-risk students were required to enroll in a one-credit hour performance-management course. They met weekly with a student staff member and prepared a contract, which specified their goals for the upcoming week and evaluated the past weeks' accomplishments. The students were also required to graph their daily accomplishments and spend ten hours per week studying …

The Effects Of A Structured Study-Support Program On The Academic Performance Of Minority College Freshmen In A General Psychology Course, Mark Andrew Jackson

Masters Theses

This study analyzed the effectiveness of a structured study support course on the academic performance of minority college freshmen in a general psychology course. The study-support course required the participants to study the weekly quiz material in specified increments throughout the entire week. These participants received significantly higher grades than those who did not.

In addition, the weekly quiz scores of the participants during the treatment phase were significantly higher than their quiz scores prior to the beginning of the study-support course. Students who did not participate in the study-support course showed no significant difference in weekly quiz performance during …

A Performance Audit Of A Graduate Training Program, Maria Emma Garcia

Masters Theses

The present study consists of a performance audit of a graduate training program. The performance audit is an engineering model created by Gilbert (1978) to design, analyze, and evaluate organizations. This performance audit was applied to the Behavioral Systems Analysis Program (BSAP), a graduate training program of the Psychology Department at Western Michigan University. The mission of BSAP consists of training behavioral systems analysts to effectively create or improve systems that benefit humanity.

This study had two objectives: first, the identification of the areas of BSAP with greatest potential for improvement and the identification causes of their deficiencies; second, to …

The Delay-Reduction Hypothesis Of Evocative Effectiveness And Latency, James Bryant Nuzzo

Dissertations

Prior studies found that separations between latencies correlated with differential stimuli in a multiple discrete trial procedure were attenuated with increased intertrial interval durations. In this study six pigeons served as subjects in two groups. The procedure for one group was a multiple DRO-FR chain schedule (Ratio Delay group) while in the other group a multiple DRO - response-initiated delay interval chain schedule (Time Delay group) was used. Results of this study are consistent with the Delay-reduction hypothesis of evocative effectiveness which predicts that with increasing initial link durations relative terminal link evocative effectiveness would decrease. Specifically, relative terminal link …

Stimulus-Reinforcer And Response-Reinforcer Relationships In The Determination Of Response Latency, Bruce Edward Hesse

Dissertations

Response latency is measured from the onset of a stimulus to the onset of a response and is relevant to both respondent and operant control procedures. Previous research has shown response latency to be a sensitive operant dependent variable but the contribution of respondent influences was not known. The present experiment used pigeons, a two-key procedure and a two component FR schedule to study the respondent (stimulus-reinforcer) contributions to the determination of an ostensibly operant response latency. Stimuli associated with each FR component were displayed on one key (stimulus key) while responding for reinforcement was required on a second key …

Effects Of Tripelennamine And Pentazocine Alone And In Combination On Schedule-Controlled Performance, Deborah Lou Grossett

Dissertations

The effects of tripelennamine (3, 6, 12, 18, and 24 mg/kg) and pentazocine (5, 10, 20, 30, and 40 mg/kg), given alone and in selected combinations, were determined in rats performing under fixed-ratio 30 and interresponse-time-greater-than-15-second schedules of food delivery. When given alone, tripelennamine and pentazocine produced statistically significant decreases in responding under the fixed-ratio 30 schedule, but did not significantly affect responding under the interresponse-time-greater-than-15-second schedule. Each drug alone significantly decreased the number of reinforcers (food pellets) earned relative to control values under both schedules. The effects of the two drugs in combination were supra-additive. That is, the effects …

The Use Of Performance Data To Monitor And Support The Reorganization Of An Educational System, Ellen Spall Thompson

Masters Theses

The goal of this study was to determine the performance effects on staff and students following the reorganization of a special education facility. The organizational plan was based on the development of teaching teams where students were grouped together according to exit curricular goals. Four interventions were completed in order to assess the overall outcome of the reorganization project. At the student level, the rate of learning was monitored in order to determine whether the implementation of teams affected educational objective acquisition . At the team level, meeting agendas were surveyed to find out what effect they had on student …

Prescriptive Contracting: Utilization Of Self-Monitoring And Contracting In A Study Improvement Program, Raymond L. Boettger

Masters Theses

Several factors in program design and concurrent research of study programs for academically at-risk students have been noted in reviewing the literature. Two of the most effective techniques are self-monitoring and contracting. While many of the programs based on these procedures have shown significant increases in rates of study behavior, few have reported actual academic gains. Those that have predominately used simple difference of means tests to show significance. A major drawback to many of the study improvement programs is that they require additional expense to be implemented and maintained.

Prescriptive Contracting in an Individualized Guided Study center was designed …

Use Of Contingency Contracting For The Generalization Of Social Skills Of Emotionally Impaired Students, Michelle M. Kapp

Masters Theses

The present study investigated the effects of contingency or behavioral contracting on the generalization of emitting polite words. Generalization as a result of social skills training was compared to generalization as a result of contracting. The subjects were three elementary students identified as emotionally impaired. The experimental design was a combination reversal and multiple baseline across subjects. The results of the study supported the hypothesis that contracting would be more effective than the social skills training in initiating generalization of emitting polite words. It was suggested that additional research be conducted to investigate the long term effects of contracting on …

The Effects Of Given Versus Self-Derived Rules On Children's Performance Of A Complex Discrimination Task, Susan F. Roy

Masters Theses

Two groups of preschool children were studied in a discretetrial concept formation task involving identification of stimulus cards which shared a common feature (e.g., picture a color, or a facial expression). During training, one group (rule-given) was given a verbal description which delineated the aspect of the stimulus card that should control responding. The second (self-derived rule) group was exposed to the same cards, without a rule (verbal description) being given. Members of each group were reinforced for correct responses (i.e., identifying which of two pictures had the relevant stimulus property), and accuracy of description was recorded for each trial. …

Psychometric Characteristics Of The Behavioral Observation Scale, Gregg Allen Bolt

Masters Theses

Self-, peer-, and supervisor ratings were obtained on 52 psychiatric aides using a Behavioral Observation Scale (BOS). Self ratings showed less leniency error than peer- and supervisor ratings. Halo error could not be assessed due to a negative correlation between means and variences. A multitrait-multimethod (MTMM) analysis supported the presence of strong rater bias and significant convergent validity but not discriminant validity. The results of the analyses demonstrated that the ratings obtained from a BOS were not psychometrically superior to other appraisal formats. Questions were raised as to the adequacy of a five point scale, data transformation, and rating scales.

The Psychological Aspects Of Loneliness Experienced By College Students, Jerie Kull Wood

Dissertations

Loneliness is a common problem that occurs at various life stages, but is most intense for college students. To clarify and operationalize the concepts of loneliness, several current sociological and psychological approaches to loneliness were critically examined.

The major purposes of this study were to identify the lonely among the student population, the types of loneliness they experience, the behavioral manifestations of that loneliness, and the effectiveness of an intervention method. The Belcher Extended Loneliness Scale as administered to 126 students in a pretest and 203 students in a posttest. The students also answered questions about grade point average and …

Effects Of Anticonvulsant Drugs On Learning And Memory, Mitchell Jon Picker

Dissertations

The effects of phenobarbital, clonazepam, valproic acid, phenytoin, and ethosuximide were examined in pigeons performing under repeated acquisition of response chains and delayed matching-to-sample procedures. In experiment I, clonazepam, valproic acid, ethosuximide, and phenytoin produced generally dose-dependent increases in rate of responding, while phenobarbital had little consistent effect on response rate across the dose range studied. Phenobarbital and clonazepam produced dose-dependent increases in error rates (i.e., learning impairment). Although valproic acid and phenytoin generally increased error rates relative to control values, this effect was not directly dose-dependent or consistent across subjects. In contrast to the other anticonvulsants examined, ethosuximide had …
