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 …

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.

Effects Of Feedback And Goal Setting On Job Attitudes And Productivity: A Field Study, Stephen Kildahl

Dissertations and Theses

Two theories of work motivation taken from the field of Industrial/Organizational Psychology were compared in a six-week field experiment at a Fortune 500 company. A Job Enrichment Model (Hackman & Oldham, 1975) was used and the Motivating Potential Score (MPS) of three groups of machine operators was obtained before and after a six-week productivity study. Three goal conditions based on Goal Theory (Locke, 1968) were assigned one to each of three groups of machine operators and comparisons were made between the treatment groups. Production increases resulted from providing goals and feedback to subjects, but these increases were not statistically significant. …

Effects Of Graded And Steady Exercise And Self-Confidence On Stress, Kristine M. Clarke

Dissertations and Theses

This study examined the effects of steady, graded, and no exercise on stress reduction, and the effects of self-confidence on stress reduction through exercise. Seventy-two male and female volunteers from the Portland area, ranging in age from 19-49 years, served as subjects. Subjects completed pre and post measures of the Tennessee Self-Concept Scale and the state portion of the Spielberger State-Trait Anxiety Inventory. Subjects were divided into two experimental and one control group matched according to age and exercise history. The control group kept its exercise at a minimum for eight weeks. Exercise programs for the two experimental groups consisted …

Eeny, Meeny, Miny, Mo: Self And Close-Other Selection Of Personality Test Interpretations, Sheela Word

Dissertations and Theses

In a study investigating the ability of subjects and their close friends or relatives (close-others) to recognize subject personality test results under conditions which controlled for the Barnum effect, 64 male and female undergraduate psychology students were administered the California Psychological Inventory (CPI). Each subject later attempted to choose his or her own unidentified CPI profile from among three, and a close-other of the subject independently made the same selection. It was found that 57.81% of subjects and 45.31% of close others were able to correctly identify subject profiles; these results were significant at the .0001 and .05 levels respectively. …

Mmpi And The Juvenile Sex Offender Russell Funk, Russell Funk

Dissertations and Theses

This study examined the effectiveness of the MMPI in identifying juvenile sex offenders. This study examined the hypothesis that previously identified subscales of the MMPI (i.e., Toobert et al. (1959) Pe scale and Dolan (1986) Ic scale) could be used in discriminating juvenile sex offenders (n=l 02) (and subgroups of juvenile sex offenders i.e., pedophiles n=79, and incest perpetrators n=41) from a control group of 40 juvenile offenders who had been adjudicated for non-sex related crimes. The study yielded results which indicate that the Pe subscale was not effective in discriminating pedophiles from non-pedophile sex offenders or from the control …

The Relationship Of The Perception Of Choice And Positive Behavior Change In Adolescent Residential Treatment With Future Success In The Community, Rita Harding Mcclellan

Dissertations and Theses

The purpose of this study was to explore the relationship of clients' perception of choice in treatment planning and the clients' positive behavior changes made within the treatment setting, with the clients' successful return to the community after release from the residential treatment setting.

Identifying Pedophiles With The Mmpi, Margaret M. Seits

Dissertations and Theses

The present study investigated the validity of the Pe (Toobert, Bartelme, & Jones, 1959) and Sexual Deviancy (Marsh, Hilliard, & Liechti, 1955) subscales, developed from the MMPI, to determine if the scales would discriminate convicted sexual offenders from nonsexual offenders.

The Influence Of Work Station Architecture On Work Perceptions And Work Behavior, Connie L. True

Dissertations and Theses

A field study was conducted to find whether open office architecture is related to employees' perceptions of their jobs and their work groups, and to their behavior in and around their work stations. Fifty-two employees in the administrative division of a large manufacturing operation volunteered to participate by answering a questionnaire and allowing their work stations to be analyzed for levels of visual access and visual exposure, the two independent variables. Access and exposure, at first theorized to be independent and interacting functions, were found to be too highly correlated in this open off ice setting to test as originally …
