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 …

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 …

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 …

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 …

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 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 …

The Bender Gestalt And Symbol Digit Modalities Tests As Cerebral Dysfunction Screening Instruments :A Comparative Evaluation, Bruce R. Wright

Dissertations

Problem

One of the problems confronting the psychologist in an institutional setting is the selection of appropriate instruments for the screening and diagnosis of a variety of psychological problems. Among the more subtle and yet far-reaching problems of this sort are those associated with disease, trauma, or congenital defect of the central nervous system. It was the purpose of this study to evaluate the usefulness of two well-known psychological tests as screening instruments for neurological dysfunction in a large and varied institutional population.

Method

The Bender Visual-Motor Gestalt Test (BGT) and Symbol Digit Modalities Test (SDMT) were administered to one …

Relationship Between Four Temperament Types And Nineteen Spiritual Gifts, Roland L. Joachim

Dissertations

Problem. No studies have been found that examine empirically the possible relationship between temperament and spiritual gifts. Traditionally they have been seen as offspring of discrete disciplines, the former belonging to the realm of psychology and the latter to theology. When some writers recently hypothesized a possible correlation between temperament and spiritual gifts, others discredited the notion.

This study was undertaken to investigate the possible correlation between the traditional four temperament types and a selection of nineteen spiritual gifts of the New Testament.

Method. The data base for this study consisted of 1,067 Christian graduate students and church members from …

A Comparative Study Of The Psychological Profiles Of A Selective Sample Of Incarcerated Females Versus Non-Incarcerated Females, Karen Ladd

Dissertations

Problem. Psychological testing is used in penal institutions at the initial time of incarceration. The purpose of this study was to investigate the possibility of developing distinct psychological profiles for incarcerated females.

Method. The psychological assessment instrument employed to develop these profiles is the Sixteen Factor Personality Questionnaire (16PF). The data which were computed and analyzed to test the eight null hypotheses were provided by a selective sample group of 622 subjects in two penal institutions in Indiana.

Findings. (1) There is no significant difference between personality profiles of incarcerated white females who are property offenders and personality profiles of …

The Relationship Of Self-Concept, Sex, Age, Major, Anxiety, Mathematics Background, And Mathematics Ability To The Level Of Mathematics And Statistical Anxiety Among College Juniors, David John Maysick

Dissertations

Problem. One's choice of career has significant effect upon one's future life in terms of earning potential and social interaction. Mathematics/statistical anxiety and the mathematics avoidance often accompanying such anxiety, can influence career choice, causing otherwise talented people to limit their future. The purpose of this study was to determine from selected variables--particularly self-concept--which, if any, were related to the problem of mathematics and/or statistical anxiety.

Method. The statistical sample used was 350 juniors. Stratification was by degree of mathematics content in subject's major field of study. For the study, subjects had to be in the same major category as …

An Empirical Study Of The Relationship Between Religious Orthodoxy (Defined As Religious Rigidity And Religious Closed-Mindedness) And Marital Sexual Functioning, Stephen Lennard Purcell

Dissertations

Problem

This study attempted to explore whether or not a significant relationship exists between religious orthodoxy (defined as religious rigidity and religious closed-mindedness) and marital sexual functioning.

Methodology

Two Likert-type scales were developed to measure religious orthodoxy and marital sexual functioning, respectively, in a sample of 217 subjects representing Catholic, Protestant, and Jewish faiths. The relationship between the eleven indices of marital sexual functioning (overall marital sexual functioning, sexual interest, responsivity, foreplay, frequency, pleasure, inhibition, anxiety, guilt, shame, and disgust) and religious regidity, religious closed-mindedness, and four moderator variables (sex, age, education, and duration of marriage of subjects) were investigated …

Cognitive Styles And Measured Occupational Preferences Of College Freshmen And Sophomores, Leonard M. Fisher

Dissertations

Problem. This research study tested the hypothesis that significant statistical relationships obtain for junior college and college freshmen and sophomore students, between the cognitive style measures field independence/dependence, "preference for structure," Harvey's Cognitive Style Factors--and occupational factors measure by the UNIACT Interest Inventory.

Method. Four paper and pencil tests measuring three cognitive styles were administered to 213 Michiana area and junior college and college freshmen and sophomores. The Group Embedded Figures Test was used to measure field independence/dependence while the two major measures of "preference for structure" cognitive styles were the VRTTAB average, and the FRTTAB average scores of the …
