The Clinical Utility Of The Jesness Inventory, Stephanie J. Hayes-Harris

Theses, Dissertations and Capstones

Because previous research findings on the Jesness Inventory have been relatively inconsistent, the current study was conducted to further examine this instrument's reliability, convergent validity and classificatory ability. A 3 to 11 month test-retest interval used with 42 adjudicated adolescents yielded a mean correlation coefficient of .60 and suggested that the stability of the 11 individual subscales is questionable. Using 42 adjudicated adolescents and 48 outpatients, many significant correlations were obtained between the Jesness Inventory and the Adolescent Multiphasic Personality Inventory subscales. Similarly, the Asocial Index accurately classified the adjudicated adolescents as delinquent and the outpatient adolescents as nondelinquent, as …

Occupational Titles And The Perception Of Gender, Cynthia A. Lokey

Theses, Dissertations and Capstones

First, this study examines the findings of Shinar’s (1975) study on the perception of gender in occupations in comparison to a current population. Second, the answers of a population of college students in WV were compared to their place of origin. Third, current neutral titles were compared to earlier gendered counterparts. Lastly, the answers of male and female respondents were analyzed.

Overall, occupational titles were found to be less gendered but retained their gender when compared to data collected by Shinar in 1975. Those respondents who were native to in WV were not found to be more stereotypical in their …

Business Technology: New Avenues For Sexual Harassment In The Workplace, Terri Stone Meadows

Theses, Dissertations and Capstones

Evaluations of scenarios describing workplace sexual harassment rendered through interpersonal versus technological means and rendered by a supervisor versus a co-worker were made by 178 college students (95 females and 83 males; M age = 23). The participants rated the seventeen sexual harassment scenarios using a three-point scale (1 = yes; 2 =no; 3 = unsure). For each scenario, participants rated whether the behavior in the scenario (1) was sexual harassment, (2) was inappropriate, but not necessarily sexual harassment, (3) would be a comfortable experience if the participant was a target of the behavior, and (4) was serious enough to …

Peer Evaluation: Design And Implementation Of The Peer Evaluation Format, Christopher F. Nichols

Theses, Dissertations and Capstones

The following study examined the feasibility of using peer evaluation at a behavioral health center for assessing employee attitudes regarding the company’s appraisal process. A total of 30 subjects, both male and female, were chosen from a single department to pilot the peer evaluation. Subjects were surveyed in order to assess attitudes toward the process prior to participation. An outside corporation was chosen to assist in the selection of peer evaluation questions as well as compiling final ratings of each participant. A post peer evaluation survey assessed attitudes upon completion of the peer evaluation. Responses were averaged and percentages analyzed …

Results …

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

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

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

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

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

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 …

Religion And Coping With Chronic Illness: A Comparison Of Rural And Urban Communities, Christina Mullins

Theses, Dissertations and Capstones

This study compared 45 rural and urban families in their use of religion as a means of coping with the stress of a chronically ill child. Parents reported no differences between their actual use of religion as a means of coping. However, urban families were more likely to believe they should turn to their clergy for emotional support.

Sex Differences In Television Viewing And Attention: Do Males Really Channel Surf More Than Females?, Melissa Morrison

Theses, Dissertations and Capstones

Channel surfing is often thought of as a male-dominated pastime; however, previously there was no objective data supporting this conclusion. In the present study television viewing and channel surfing were monitored in 44 college students who simultaneously performed an auditory vigilance task. In addition, a survey was administered to determine self-reported individual television viewing habits. Results showed that males channel surfed at almost twice the rate of females. In addition, after the first test tone they generally detected more tones in the vigilance task than females. It was concluded the high channel surfing rate of males reflected lower levels of …

Religious Orientation And Homophobia: An Application Of The Allport And Batson Conceptualizations, Scotty K. Caudill

Theses, Dissertations and Capstones

This study elucidates the relationship between the intrinsic, extrinsic, and quest religious orientations and prejudice toward gay men and lesbians. Measures of the religious orientations, homophobia, social desirability, and demographic items were administered to 228 university student volunteers. As predicted, the intrinsic orientation correlated positively and significantly with homophobia even with social desirability controlled, and the quest orientation correlated negatively and significantly with homophobia, also with social desirability controlled. Contrary to prediction, however, the extrinsic orientation di d not correlate significantly with homophobia. These findings support previous research suggesting that an intrinsic orientation does not obviate prejudicial attitudes toward all …

A Bio-Cybernetic System For Regulating Operator Engagement In An Adaptively Automated, Multi-Task Flight Environment, Lawrence J. Prinzel Iii

Psychology Theses & Dissertations

A bio-cybemetic, closed-loop system was validated for use in an adaptively automated environment. Subjects were asked to perform either one task or three tasks from the MAT battery. EEG was continuously sampled while they performed the task and an EEG index was derived (20 beta/alpha + theta). The system made allocation decisions based upon the level of operator engagement as determined by the EEG index. The NASA-TLX was administered after each trial. The results of the study demonstrated that it was possible to moderate an operator's level of engagement through a closed-loop system driven by the operator's EEG. It also …

Math Anxiety, Coping Behavior, And Gender, Sandra Joy Grossmann

Dissertations and Theses

Non-math majors enrolled in lower-division math courses at an urban university were surveyed on their math attitudes, coping behaviors, and math anxiety (MATHANX). The Revised Ways of Coping Checklist (RWCC), Revised Math Anxiety Rating Scale, and other questions were presented to 30 men and 32 women.

Hierarchical regressions showed that after controlling for attitudinal covariates, emotion-focused coping behaviors (EMOTFOC) were strongly associated with MATHANX (F(5,54)=18.66, p < .0001), but problem-focused coping behaviors (PROBFOC) were not. The RWCC subscale most highly correlated with MATHANX was Wishful Thinking (r = .70, p < .0001). Ss were then dichotomized on PROBFOC and EMOTFOC, providing four behavioral groups. An ANCOVA controlling for attitudinal covariates showed behavioral group membership significant with respect to MATHANX (F(3,58)=6.07, p < .001), and an ANOVA revealed that students who reported high EMOTFOC coupled with low PROBFOC experienced the greatest MATHANX (F(3,58) = 12.66, p < .0001).

Males and females reported virtually identical MATHANX (M=36.30 for males, 36.44 for females), and the only significant gender difference was for avoidance coping, which was used more by males (F(1,60) = 5.43, p < .03]. Results from this study suggest that fewer gender differences may exist in MATHANX and coping than have been found in the past. Additionally, this study identifies the need for future research to determine whether EMOTFOC is the behavioral component, or one of the determinants, of math anxiety.

Upon Closer Inspection...U.S. Naval Aviation Mishaps 1977-1992, Scott A. Shappell, Douglas A. Wiegmann

Publications

The U.S. Navy/Marine Corps Class A flight/flight-related mishap rate has declined markedly since 1953. However, analysis of all Class A, B, and C naval aviation mishaps between January 1977 and December 1992 reveals that mishaps attributable to human factors have declined at a slower rate than those attributable to mechanical/environmental factors. Upon closer inspection of the data, marked differences were evident between single-piloted and dual-piloted aircraft. Global trends were primarily a function of single-piloted aircraft, particularly when phase of flight and time of day that a mishap occurred are considered. Previously reported improvement in aviation safety may be biased by …

Publications

The fatigue and cognitive performance deficits associated with sleep loss and stress have motivated the search for effective nonpharmacological countermeasures. The purpose of the present study was to examine the potential behavioral effects of tyrosine, an amino-acid presursor to dopamine and norepinephrine, during an episode of continuous nighttime work involving one night of sleep loss.

Behavioral Effects Of Tyrosine During Sustained Wakefulness, D. L. Wiegmann, D. F. Neri, R. R. Stanny, S. A. Shappell, A. H. Mccardie, D. L. Mckay

Publications

The fatigue and cognitive performance deficits associated with sleep loss and stress, like that experienced during sustained flight operations and nighttime flying, have motivated the search for effective nonpharmacological countermeasures. The behavioral effects of the potential countermeasure tyrosine, an amino-acid precursor to dopamine and norepinephrine, were examined during an episode of continuous nighttime work involving one night's sleep loss. Volunteers performed nine iterations of a battery of cognitive and subjective tasks for approximately 13 h, beginning at 1930 and ending at 0820 the following morning. Subjects remained awake throughout the day on which the experiment began and were awake for …

Work/Rest Schedules And Performance Of F/A-18 Aviators During Fleet Exercise 1992, Scott A. Shappell, David F. Neri

Publications

As a continuation of our previous work during Operation Desert Shield/Storm, we examined the effect a fleet exercise has on the work/rest patterns, fatigue, and cognitive performance of F/A-18 aviators. For 10 days during Fleet Exercise 1992, 25 pilots from VFA-81 and VFA-83 completed daily work/rest logs while performing their usual tasks. Subjective measure of fatigue, quality of rest, and sleep need were also collected. A subset of these F/A-18 pilots completed a brief battery of cognitive tasks as soon before flying as possible and again after the flight debrief. As a group, the pilots were adequately rested with little …

Work/Rest Schedules And Performance Of S-3 Aviators During Fleet Exercise 1992, David F. Neri, Scott A. Shappell

Publications

We examined the effect that a fleet exercise has on the work/rest patterns, fatigue, and cognitive performance of S-3 aviators. For 10 days during Fleet Exercise 1992, 21 S-3 aviators from CARRIER AIR WING SEVENTEEN (CVW-17) aboard USS SARATOGA (CV-60) completed detailed daily-activity logs while performing their usual tasks. Subjective measures of fatigue, quality of rest, and sleep need were also collected. A subset of eight aviators completed a brief battery of computer tasks as soon before flying as possible and again after flight debrief. Results indicated that, although the fleet exercise appeared to be below average in difficulty, there …

The Cry-Wolf Phenomenon And Its Effect On Alarm Responses, James P. Bliss

Retrospective Theses and Dissertations

Responses to alarms are assumed important. Yet failure to respond to alarms is recognized, although is not well understood or quantified. Conditions that might induce a failure to respond include alarm unreliability (i.e., numerous false alarms, the "cry-wolf" effect), high primary task demand, or low criticality of the alarm itself. The goals of this research were to substantiate the existence of the cry-wolf effect, quantifying its effect on operator performance, and to examine the relation between the cry-wolf effect and alarm criticality. One hundred thirty-eight UCF students alternatively performed two primary tasks, chosen from the Automated Performance Test System. Subjects …

Subjective Fatigue In A-6, F-14, And F/A-18 Aircrews During Operations Desert Shield And Storm, C. A. Dejohn, S. A. Shappell, D. F. Neri

Publications

Fatigue occurring during naval air combat can reduce performance, impair operational effectiveness, and compromise safety. This study examines the effect of combat missions on the subjective fatigue of naval aircrews deployed aboard USS AMERICA during Desert Shield and Desert Storm. Fatigue was determined using three questionnaires that were completed before and after each mission. Although fatigue significantly increased during combat missions, it usually returned to preflight levels by the next day without noticeably increasing as the operation progressed. We feel that judicious aircrew scheduling on the part of operational planners was one of the most important factors contributing to this …

Effects Of Dextro-Methamphetamine On Subjective Fatigue, C. A. Dejohn, Scott Shappell, D. F. Neri

Publications

Declining aircrew performance during periods of sustained flight operations (SUSOPs) has underscored the need to develop effective countermeasures. This paper reports on the ability of the central nervous system (CNS) stimulant d-methamphetamine to alleviate the detrimental effects of a simulated SUSOPs on subjective fatigue. Subjective fatigue was repeatedly measured by three questionnaires. The simulated SUSOP started at 1800 and consisted of a 9-h planning session followed by 4 h of rest and a 14-h mission. After 6 h of sleep, the 9/4/14 work/rest/work pattern was repeated. At 4 1/2 h into the second mission, 13 subjects were administered 10 mg …

The Effect Of Combat On The Work/Rest Schedules And Fatigue Of A-6 And F-14 Aviators During Operation Desert Shield/Storm, David F. Neri, Scott A. Shappell

Publications

During Operation Desert Shield/Storm, A-6 and F-14 aviators aboard USS AMERICA completed daily activity logs and provided subjective measures of fatigue. Aviators flew frequently at night during Desert Storm, but without substantial sleep-related fatigue or problems. A likely contributing factor was the large number of naval aviation assets brought into the combat theater, allowing workload to be shared and activity and rest times to be properly managed. However, raster plots of the data suggest that there may have been an additional contributing factor. The AMERICA travelled eastward from the east coast through seven time zones and became involved in combat …

The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri

Publications

The effect of operational tasking on aircrew readiness during combat operations continues to be an area of intense investigation within the U.S. Navy. The recent Persian Gulf War provided a unique opportunity to collect data examining aircrew work/rest cycles and operational tasking in a combat environment. For 4 consecutive weeks during Operations Desert Shield and Desert Storm, 18 A-6 and 18 F-14 aviators onboard the USS AMERICA (CV-66) completed daily work/rest logs of their activities while conducting operations from the Red Sea. Activities on the work/rest logs were coded to a resolution of one-half hour. Several flight parameters were also …

An Introduction To The Five-Factor Model And Its Applications, Robert R. Mccrae, Oliver P. John

United States Public Health Resources

The five-factor model of personality is a hierarchical organization of personality traits in terms of five basic dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Research using both natural language adjectives and theoretically based personality questionnaires supports the comprehensiveness of the model and its applicability across observers and cultures. This article summarizes the history of the model and its supporting evidence; discusses conceptions of the nature of the factors; and outlines an agenda for theorizing about the origins and operation of the factors. We argue that the model should prove useful both for individual assessment and for the elucidation …

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh

Publications

Investigations of aircrew sustained operations (SUSOPS) have been criticized for employing tasks with no apparent external validity. Because measures obtained directly from aviators flying high-performance aircraft are difficult to obtain, a laboratory compromise is needed. High-fidelity flight simulators used for aircrew training offer the most realistic simulation, but their availability is limited. Personal computer-based flight simulators may provide adequate simulation in, the laboratory at a reasonable cost. This report describes a representative research protocol using a commercially available flight simulator during a simulated aircrew SUSOP.

Communicating With Graphic User Interfaces: A Comparison Of Menu Selection And Menu Bypass Techniques, Monty Lee Hammontree

Psychology Theses & Dissertations

The present study was conducted in two phases to determine design tradeoffs relating to command bar menu and bypass code-based techniques for interacting with computers. Forty eight subjects participated. In the first phase of the experiment, mouse-, chorded key-, and function key-based menu selection techniques were compared. It was found that menus were accessed much faster with spatially mapped function keys as compared to chorded key sequences or mouse inputs, and that relative to mouse inputs compatible letter keys lead to faster command selection times. Further, the function key-based technique yielded the fastest combined access and selection times, the fastest …

The Effect Of Fear Of Success And Perceived Task Difficulty On Cognitive Performance, David Eugene Elkins

Psychology Theses & Dissertations

This study investigated the relationship of fear of success (FOS) and perceptions of task difficulty, their interactive effect on anagram and matrix-task performance and possible gender differences on these variables. A total of 226 students, 83 males and 143 females, participated in the study. FOS was measured by the administration of Zuckerman and Allison's (1976) Fear of Success Scale. Perceptions of task difficulty were manipulated by use of falsified normative data. Subjects therefore believed the upcoming task was either easy or difficult or the subjects were employed as controls. An anagram task and 12 items selected from Raven's Standard Progressive …
