The Effects Of Hydrocortisone And Caffeine On Memory For Word Lists, Daniel L. Scharf

Theses and Dissertations

Hydrocortisone has frequently been hypothesized to increase arousal. This hypothesis was primarily based on the findings of increased adrenal size in animals who had been exposed to stressful conditions and the enhancement or impairment in cognitive abilities of humans depending on dose. There has been a lack of studies directly looking at the arousal hypothesis of the effects of hydrocortisone. The purpose of this study was to directly assess the effects of hydrocortisone on levels of arousal by manipulating both state and trait arousal. This study used caffeine as a comparison drug that alters state arousal because of its widely …

An Analogue Of Science, Michael Albert Minervini

Dissertations

There is no science of human behavior, not even an incipient one. The popular conception of applied behavior analysis as a genuine principle-driven technology is mostly an illusion. Two sorts of evidence support this conclusion. The first is an ever widening split between the field's basic and applied realms. The second, thus far unacknowledged, is that when the concepts of operant and respondent conditioning are extended to human behavior, they are often rendered as no more than metaphors. These metaphors are not confined to casual discourse or even to interpretation. In fact, they are the prevailing form of extension in …

Productivity And Affective Responses To Work Tasks And Leisure Activities In Type A And Type B Individuals, Susan Jean Paske

Masters Theses

The Type A Personality Index, a measure of whether an individual tends to be a Type A or a Type B personality, was given to 30 male and 30 female college students who then participated in a planting activity, presented as either a work task or a leisure activity. Productivity was measured by number of pottings, and affective responses to the activity in the areas of evaluation, power, and action were determined by Osgood's 12-scale short form semantic differential (OSD). No significant correlations were found between personality type and productivity or OSD scores in either the work or leisure conditions. …

Perceived Severity Of Informal Sanctions: A Case Study Of Convicted Dui Offenders In Cass County, North Dakota, Terry D. Stratton

Theses and Dissertations

It Is estimated that alcohol plays a factor in between 35 and 64 c'-rcent of all fatal crashes and between 6 and 25 percent for non-fatal accidents, resulting in alcohol .being involved in about half of the roughly 50,000 annual traffic fatalities in the United States. Clearly, drinking-and driving is a major contributor in both the severity and the frequency of traffic accidents.

The basic concept of deterrence states that people will refrain from behavior defined as socially-unaccc.ptable if the resulting perception and fear of penalties (or sanctions) against such action are adequately undesirable in comparison to the potential benefits …

The Incestuous Family: Development Of An Enmeshed Family Inventory, Loretta M. Petrie

Theses and Dissertations

A systems model has been proposed as useful theoretical framework for the study of incestuous families (Alexander, 1985) and is frequently used in the therapeutic treatment of the victim of sexual abuse and his or her perpetrator (Larson and Maddock, 1986). The purpose of this study was the construction and standardization of an instrument for assessing a multiaxial model of enmeshed and disengaged family systems which is based on the prior work of Minuchin et al. (1978) and Kog et al. (1987).

Minuchin et al. (1978) suggest that enmeshment, conflict-avoidance, over-protectiveness and rigidity are four characteristics that are key to …

The Development Of A Personalized Computer Assisted School Psychology (Casp) System, Patricia Lou Steinert

Dissertations

The purpose of this project was to develop a model computer system to assist school psychologists in managing and manipulating data accumulated in the course of accomplishing their professional responsibilities. School psychologists have traditionally generated large amounts of data, but rarely have they looked across these data to obtain information and/or feedback about their own functioning relative to their professional role. The system described is intended as a model from which an individual psychologist might construct a system to meet individual needs. Data across students were accumulated in four broad areas: (1) personal effectiveness/accountability, (2) diagnosis, (3) local test norms, …

The Psychological Needs Of Sex Offenders Of Children As Measured By The Personality Research Form, Shirley Anne Miller

Dissertations

Major contributors in the field of child sexual abuse have agreed that sex offenders who sexually abuse children are not primarily motivated by sexual desire and have proposed that the simultaneous satisfaction of a number of psychological needs is the prominent motivation of sex offenders of children. Few attempts have been made to empirically validate the clinical and theoretical impressions regarding the psychological needs of this group using psychological measures designed to assess needs or motives.

The purpose of this study was to investigate to what extent the assumptions about the psychological needs of sex offenders of children would be …

Development Of A Weighted Application Blank For The Carryout Clerk Classification In A Large Retail Organization, Linda Gabbard

Masters Theses & Specialist Projects

The purpose of this study was to develop and validate a Weighted Application Blank to predict turnover for use as a selection tool for a large retail organization. Utilizing the England (1971) procedure, it was hypothesized that significant derivation and cross-validities would be obtained. The hypothesis was partially supported: the derivation validity coefficient was significant (r = .28, p < .01) and the resulting cross-validity coefficient was net significant (r = 19, p < .05). The results and recommendations for implementation of the WAB are discussed.

Comprehension Of "Absence" By An African Grey Parrot: Learning With Respect To Questions Of Same/Different, Irene M. Pepperberg

Sentience Collection

An African Grey parrot, Alex, learned to report on the absence or presence of similarity and difference between two objects. Alex was shown pairs of objects that were (a) totally dissimilar, (b) identical, or (c) similar or different with respect to one of three attributes (color, shape, or material). In the first two cases, he responded to the respective queries of "What's same?" or "What's different?" with the vocalization "none," and in the third case he responded with the appropriate category label ("color," "shape," or "mah-mah" [matter]). His accuracy was 80.9% to 83.9% for pairs of familiar objects not used …

Effects Of Flat Panel Display Parameters Across Three Application Areas Upon Similarity Judgments, Novia Weiman

Dissertations and Theses

A human performance experiment was conducted to investigate pixel parameter requirements for three types of flat-panel display images: an alphanumeric character, an oscilloscope waveform, and a real-world image. Subjects performed similarity judgments between an extremely high-quality image and an image composed of different levels of anti-aliasing and pixel width-plus-pixel separation (pitch). It was found that the effect of pitch had greater influence on perceived image quality for the alphanumeric character and oscilloscope waveform than for the real-world image. The results of this research provide empirical evidence showing that the pixel pitch requirements for flat-panel systems that are used to display …

The Effect Of Sex, Gender Identity, & Sex Of Story Characters On The Assessment Of Moral Development, Cathy Frey

Masters Theses & Specialist Projects

The present study investigated the three areas associated with sex bias in Kohlberg's theory of moral development --sex, gender identification, and sex of story characters. The Defining Issues Test (DIT: Rest,1986a), a measure of moral development derived from Kohlberg's theory, was used in its original form and two revised forms (Male and Female versions) to determine the effects of sex and sex of story characters on the assessment of moral development. The Bem Sex -Role Inventory (Bem, 1981) was used to classify subjects as either sex -typed or androgynous to determine whether sex -role identification affects the assessment moral development. …

The Effects Of Irrelevant Dimensions On The Predictive Value Of A Warning Signal, Ruth Justine Arnegard

Psychology Theses & Dissertations

Past research has neglected irrelevant dimensions of visual warning signals in choice reaction-time tasks. The present study examined the effects of an irrelevant dimension of a visual warning signal and that signal's value in predicting a response stimulus on choice reaction time. A warning signal, which was a geometric figure, appeared in the center of a VDT screen and was followed by one of two response stimuli (open circles). The predictive value of the warning signal was defined as the percentage of trials during which the warning signal accurately predicted the response stimulus by size and was manipulated in the …

Views Of Cesarean Birth Among Primiparous Women Of Mexican Origin In Los Angeles, Laura H. Cummins, Susan C. M. Scrimshaw, Patrice L. Engle

Psychology and Child Development

This study examined data from a larger project on the cultural context of first birth among low-income women of Mexican origin giving birth in Los Angeles. Data on knowledge of cesarean birth and perceptions of the cesarean birth experience were collected. In addition, differences in perceptions of the experience between women giving birth vaginally and those giving birth by cesarean as reported in the literature were assessed. Five hundred eighteen women were surveyed, of whom 58 had a cesarean birth. Statistical analyses revealed few significant differences between the two groups with regard to childbirth knowledge and attitudes, which may indicate …

The Effect Of Deliberate Faking Good And Faking Bad On Spiritual Well-Being Scale Scores In A Church Sample, Alice V. Moody

Doctor of Psychology (PsyD)

This study investigated the effect of faking (good and bad) on Spiritual Well-being (SWB) Scale scores. It is a true experiment with three levels of the independent variable: fake good, honest responding, and fake bad instructions. The sample consisted of 172 adults from a community church Sunday School class and a group for those overcoming some addiction and/or abuse. A demographic questionnaire was given along with the SWB Scale. An analysis of variance was run for each of the dependent measures: SWB and its two subscales, Religious Well-being (RWB) and Existential Well·being (EWB) . ANOVA and Scheffe post hoc test …

Spatial Vision: Age And Practice, James Pasley

Masters Theses & Specialist Projects

Previous studies have shown that practice can improve adults’ ability to discriminate between two similar high frequency spatial patterns. Adults trained on this task also demonstrated significant improvement on a standard acuity test which is dependent on high frequency information. The aim of this study was to extend the range of training patterns to low (1.7 c/deg) and middle (4.0 c/deg.) spatial frequencies, and to determine if practice in a similar spatial frequency discrimination task would transfer to other spatial tasks dependent on low frequency information. Fourteen subjects in three age groups (young, middle and old) were tested before and …

The Effect Of Social Context & Group Decision Making Formats On An Evaluative Task, Joyce Bowers

Masters Theses & Specialist Projects

A review of the literature on decision making indicated a lack of research attention given to the effects of the dynamics of the social context surrounding participation on decision outcomes. The present study examined the relationship between social context and group decision making formats, and its implications for the effective implementation of group participation in decision making The effectiveness of three decision -making formats, the nominal technique, the interacting technique, and the consensus technique, were compared under conditions of cooperation and competition on the three decision effectiveness dimensions of quality, acceptance, and synergy.

Two-hundred and forty-eight undergraduate students, working in …

Sex Role Orientation And Self-Esteem Of Female Varsity Athletes, Recreational Athletes And Nonathletes, Jo Ann Utley

Masters Theses & Specialist Projects

The relationship between athletic participation, sex role orientation and self-esteem has received little attention from researchers and the relationship of these variables among females has not received as much attention as it has among males. It has been theorized that participation in sports, particularly team sports, may effect an increase in self-esteem due to increased positive body image and tend to “masculinize” women and/or attract females who possess or value more masculine traits and behaviors.

To address these issues, a comparison of sex role orientation and level of self-esteem was made with female varsity athletes, recreational athletes and nonathletes at …

The Treatment Of Test Anxiety Using Stress Inoculation Training, James L. Mason

All-Inclusive List of Electronic Theses and Dissertations

The purpose of this study was to test the effectiveness of a stress inoculation training package based on recommendations provided in the Meichenbaum and Butler feedback loop model of test anxiety. The variables under investigation included the Test Anxiety Scale, the Study Habits scale of the Survey of Study Habits and Attitudes, and academic test scores (converted to standard scores). These measures were administered pre- and posttreatment. The sample consisted of 54 introductory psychology students who were self-identified as test-anxious. Through a randomization process, 26 students were assigned to the stress inoculation training group and 28 students were assigned to …

A Review Of Surveys Of Professional Practice In Psychology Since 1961: Trends And Future Challenges, Geoffrey E. Buck

All-Inclusive List of Electronic Theses and Dissertations

Psychology has enjoyed tremendous growth and increasing professionalization in the years following WWII, with the major thrust of this growth being in professional practice. This period has also witnessed a rapid transformation in the educational and sociopolitical underpinnings of professional training and practice. Many authors have studied the growth of practice by periodically surveying practitioners and commenting on a wide variety of demographic, professional and practice-related characteristics. This paper reviews these surveys, noting trends in the characteristics of the human resource pool and the factors both within and external to the profession that have contributed to the shape of those …

An Analysis Of Four Empathy Variables As Predictors Of Marital Satisfaction, Teck Seong Chee

Masters Theses

The objective of this study was to determine if empathy was predictive of marital satisfaction, and which, if any, of the four empathy variables from Davis' Interpersonal Reactivity Index (1980), would serve as predictors of marital satisfaction. Correlation and regression analyses were used to evaluate the relationships of fantasy, empathic concern, perspective taking and personal distress with marital satisfaction. Variables of secondary interest included those of sex. birth order, length of marriage and age married. Both Individuals and couples were used as units of analysis.

Empathic concern and perspective taking were found to be predictors of marital satisfaction. No significant …

The Moderating Effects Of Evaluation Apprehension And Group Goals On Social Loafing, Thomas Rauzi

Student Work

The social loafing effect, that subjects work harder alone than in groups, was contrasted against the use of two motivational techniques. Subjects were 80 undergraduate students at a midwestern university. A 2 x 2 factorial design was employed contrasting the use of group goals with the salience of evaluation apprehension. Subjects, working in groups of four, were asked to generate possible uses for common objects during two timed work periods. Results provided support for an Interaction Hypothesis: that group goal or evaluation apprehension conditions are sufficient to increase performance over a social loafing replication condition. However, the actual presence of …

The Effectiveness Of Feedback Procedures On Machine Set-Up Time In A Manufacturing Setting, Connie J. Wittkopp

Dissertations

The purpose of the present study was to evaluate the effectiveness of a treatment package designed to improve and maintain set-up time in the extrusion department of a rubber manufacturing company. Subjects were exposed to various behavioral techniques including training and a feedback system in the form of both written and verbal supervisory comments with an emphasis placed on improving performance through use of videotaping. An attempt was made to maintain treatment gains by teaching supervisors how to give information concerning set-up performance to their employees. Results indicate that average weekly set-up times for each machine were significantly below baseline …

Self-Control In Mentally Retarded Adolescents: Choice As A Function Of Amount And Delay Of Reinforcement, Steven P. Ragotzy

Dissertations

Three severely mentally retarded adolescents were studied under discrete-trial procedures in which a choice was arranged between edible reinforcers that differed in magnitude and, in some conditions, delay. In the absence of delays, the larger reinforcer was consistently chosen. All subjects directed the majority of choice responses to the smaller reinforcer when the larger reinforcer was sufficiently delayed, although the value at which this occurred differed across subjects. Under conditions where the larger reinforcer initially was sufficiently delayed to result in preference for the smaller one, progressively increasing in 5-s increments the delay to both reinforcers increased percent trials with …

Effects Of Task Difficulty, Performance Consequence, And Social Interaction On Physiological Reactivity In Post-Coronary Patients, A. Janelle Maldonado

Dissertations

Three experiments were performed to determine the effects of three task variables and Type A behavior pattern on physiological reactivity to time-limited math and anagram tasks. In the first experiment, ten post-coronary patients performed time-limited computer tasks under two performance consequence conditions: Point Reward or presentation of an Auditory Blast combined with two task difficulty conditions (40% and 60% difficult). The findings of Experiment 1 indicated that while the tasks did produce levels of physiological reactivity comparable to those observed in the literature, there were no significant main effects for either variable for any of the five measures. A significant …

Studying Situations And Identities Using Experiential Sampling Methodology, Peter J. Burke, Stephen L. Franzoi

Psychology Faculty Research and Publications

This paper explores a central question in social psychology: How are particular meanings of particular identities selected in a situation? This question was examined in a field setting, using experiential sampling techniques in which participants carried an electronic timer for two days as they engaged in their normal activities on a college campus. When the timer signalled them, participants responded to a questionnaire concerning who they were with, what they were doing, what identities and roles they were involved in at the time, and what their perceptions were of the situation. From the work of Burke and Reitzes, which postulates …

Choice Responding In Pigeons Exposed To Sequences Of Fixed-Ratio Schedules: Effects Of Multiple Components, Susan Goeters

Masters Theses

The present study used a discrete-trials procedure to examine choice in pigeons presented with two- to five-component sequences of fixed-ratio schedules of reinforcement. Results of the first phase indicate that the majority of choice responses were allocated to the schedule containing the shorter initial fixed-ratio component regardless of the number of components assayed. These findings support the notion that temporally prior reinforcers minimize the effects of subsequent reinforcers and overall response requirements. Phase two findings indicate, however, that under some conditions, fixed-ratios other than the first, lawfully, although weakly, influence choice.

Advertising In Restrooms, Karsten C. Hofmann

Dissertations and Theses

There is a common belief that the special situation one encounters in restrooms is likely to evoke negative associations between the setting and a potential product, and that these presumed associations make advertising in restrooms incompatible with the objectives of advertisers.

This general proposition was questioned on theoretical grounds. It was argued that the specific situation in a restroom would be conducive to advertising goals in a number of ways. In addition, while negative associations may occur with certain kinds of products, others were hypothesized to be unaffected. In particular, the potential value of restrooms for communicating public education issues …

Beyond Difference Scores: Testing Models Of Speed Of Information-Processing Using Confirmatory Factor Analysis, Gary A. Uhland

Dissertations and Theses

This study has two parts: Part I discusses the limitations of difference scores and exploratory factor analysis for representing speed of information-processing stages in the context of a reanalysis of a study by Vernon (1983). Vernon interpreted the differences between objectively measured reaction times on various simple cognitive tasks as components of speed of information processing. Correlations were calculated among these differences and subjected to exploratory factor analysis. The factors obtained from this analysis were interpreted by Vernon in terms of short-term and long-term memory processing constructs. The use of difference scores, however, implies an additive model allowance for random …

Eating Disorders: The Correlation Of Family Relationships With An Eating Disorder Continuum, Jana Schweitzer

Dissertations and Theses

For the purposes of this study, eating disturbances were placed on a continuum ranging from disordered to normal, and family factors were examined via this framework. Research on anorectics and bulimics indicates that a variety of family variables contribute to the etiology of eating disorders. Research suggests the presence of a subgroup of persons who experience some disturbance in their relationships with food but not to the severity observed among eating disordered individuals. This study examined the relationship between family factors and eating disturbances.
