Subjective Quality Of Experience With The Internet: Accounting For Temporal Changes In User Acceptance Of Information Technology, Jason M. Turner Dec 1997

Subjective Quality Of Experience With The Internet: Accounting For Temporal Changes In User Acceptance Of Information Technology, Jason M. Turner

Theses and Dissertations

Contemporary information technology (IT) related research has focused on use as a key dependent measure for valuing IT. By understanding the determinants of IT use, we gain descriptive information about successful IT, and prescriptive information for better deploying IT resources. Although there are several competing theories regarding IT use, research findings often cite their inability to account for temporal changes in usage behaviors. This thesis introduces quality of experience as a potential moderator between the determinants of use and actual usage behaviors. A pilot survey concerning Internet usage generated potentially relevant items which were later refined into a questionnaire assessing …


The Effects Of Task Partitioning And Computer Skill Level On Operator Engagement And Performance In An Adaptive Biocybernetic Environment, Todd Michael Eischeid Oct 1997

The Effects Of Task Partitioning And Computer Skill Level On Operator Engagement And Performance In An Adaptive Biocybernetic Environment, Todd Michael Eischeid

Psychology Theses & Dissertations

The present study examined task partitioning in an adaptive environment, utilizing the cybernetic closed-loop system of Pope et al. (1995). In that study, participants either performed a tracking task (manual condition) or monitored the tracking task (automatic condition). Changes in task mode were driven by an engagement index derived from the participant's EEG and operated under either positive or negative feedback conditions. One goal of the present study was to examine participant performance under a wider range of tracking conditions. Specifically, the task was partitioned into 3 modes: a manual mode, a partitioned mode, and an automatic mode. A second …


The Role Of Alcohol And Stress On Measures Of Depression And Anxiety Among College Students, Jeffrey F. Porter Aug 1997

The Role Of Alcohol And Stress On Measures Of Depression And Anxiety Among College Students, Jeffrey F. Porter

Masters Theses

In clinical literature regarding the effects of regular alcohol use, psychological benefits of moderate consumption have been suggested (Neff & Husaini, 1982; Neff, 1984; Neff & Husaini, 1985; Neff, 1985; Neff, 1986; Neff, 1993, Lipton, 1994). Despite the diverse groups with which this theory has been examined, no published studies have lookeq specifically at the high-risk group of college undergraduates. Subjects were surveyed to assess their typical drinking behavior, the number of stressful events they had experienced within the past 12 months, their perceived social support, and depressive and anxiety symptoms they experienced within the seven days leading up to …


The Effects Of Cognitive-Behavioral Therapy On Anxiety Among The Elderly In A Nursing Home Setting, Lawrence David Parker Jan 1997

The Effects Of Cognitive-Behavioral Therapy On Anxiety Among The Elderly In A Nursing Home Setting, Lawrence David Parker

Theses, Dissertations and Capstones

This study evaluated the effects of cognitive-behavioral therapy on the severity of anxiety among the elderly in a nursing home setting. Eighteen adults were involved in the research. The Beck Anxiety Inventory (BDI) was used for a pre-test, post-test, and delayed post-test measures. The results of the t-test indicated a significant difference between the pre-test and the post-test measures in the experimental group. The significant difference was not, however, maintained over time. The results of t-test between the pre-test delayed post-test for the experimental group was non-significant. The results of the study suggested that cognitive-behavioral therapy training did have a …


A Concurrent Validity Study Of The Kaufman Brief Intelligence Test And The Wechsler Adult Intelligence Scale - Revised, Kimberly D. Rayburn Jan 1997

A Concurrent Validity Study Of The Kaufman Brief Intelligence Test And The Wechsler Adult Intelligence Scale - Revised, Kimberly D. Rayburn

Theses, Dissertations and Capstones

The Kaufinan Brief Intelligence Test (K-BIT) as a valid screening instrument for the more comprehensive Wechsler Adult Intelligence Scale-Revised (WAIS-R) was studied. Both assessment instruments were administered to 34 subjects referred to a private psychological practice as part of a requested battery of test. Each test produces a verbal score, nonverbal score and combined verbal and nonverbal score. Results indicate that each section of the K-BIT has a significant correlation to its WAIS-R counterpart. The correlation between the verbal scores, nonverbal scores and the combined scores of the two instruments were .87, .78, and .88, respectively. The K-BIT appears to …


Attachment And The Development Of Eating Disorders As Measured By The “Apdq”, Colleen D. O'Pell Jan 1997

Attachment And The Development Of Eating Disorders As Measured By The “Apdq”, Colleen D. O'Pell

Theses, Dissertations and Capstones

The impact of family of origin dynamics on the development and maintenance of eating disorders is well documented in the literature. This study sought to investigate the attachment relationships and personality characteristics of eating disordered subjects by administering the Attachment and Personality Dynamics Questionnaire (APDQ). It was hypothesized that the eating disordered subjects would show a pattern of insecure attachments to primary caregivers and significant others in comparison to controls. A total of 23 eating disordered females and 297 female control subjects completed the APDQ. The t tests for the 29 scales of the APDQ revealed lower means for the …
