Pilot Performance And Eye Movement Activity With Varying Levels Of Display Integration In A Synthetic Vision Cockpit, Julie Michele Stark

Psychology Theses & Dissertations

The primary goal of the present study was to investigate the effects of display integration in a simulated commercial aircraft cockpit equipped with a synthetic vision display. Combinations of display integration level (low/high), display view (synthetic vision view/traditional display), and workload (low/high) were presented to each participant. Sixteen commercial pilots flew multiple approaches under IMC conditions in a moderate fidelity fixed-base part-task simulator. Pilot performance data, visual activity, mental workload, and self-report situation awareness were measured.

Congruent with the Proximity Compatibility Principle, the more integrated display facilitated superior performance on integrative tasks (lateral and vertical path maintenance), whereas a less …

Euthanasia: An Exploration Of Public Opinion, Debra M. Babylon

Sociology & Criminal Justice Theses & Dissertations

The acceptance of euthanasia is examined using the 1972-2002 GSS cumulative dataset. The dataset contains a total of 43,698 respondents. The euthanasia question, "Should a terminally ill patient be allowed the right to die?" was asked beginning in 1977. The number of respondents answering the euthanasia question totals 22,039. The independent variables age, race, gender, political view, religious affiliation, and education were reviewed to assess their impact on support of euthanasia. Additionally, in order to test the "slippery slope" hypothesis, the abortion question, "Should abortion be allowed under any circumstance?" was added to the independent variable list. Cross tabulation was …

Comparisons Among Parent Reports And Self-Reports Of Sleep In Adhd And Normal School-Aged Children, Diana M. Turner-Eadie

Psychology Theses & Dissertations

The objective of the study was to investigate whether school-aged children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) experience greater sleep disturbance than do normally-developing children. Participants included 33 parents and their children with ADHD (mean age = 10.7 ± 1.7 years) and 33 parents and their children without ADHD (mean age = 10.7 ± 1.6 years). Both parents and their children completed sleep questionnaires developed to assess a number of sleep variables. Based on parental report, the Total Sleep Disturbance score was significantly greater for the ADHD group than for the comparison group. Parents indicated that children with ADHD had …

Crisp And Fuzzy Signal Detection Theory And Pilot Weather Judgment: Implications For Vfr Flights Into Imc, Joseph T. Coyne

Psychology Theses & Dissertations

Weather represents one of the greatest hazards to general aviation (GA), accounting for 15% of the GA accident fatalities. Of the fatal weather accidents 90% are attributed to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) and IMC. An alternative hypothesis is that pilots recognize conditions have deteriorated but are motivated by some other factor, such as pressure from passengers. The present study uses Jensen's Pilot Judgment Model and Signal Detection Theory to explain …

The Psychological Contract Of Multiple Agency Relationships: Understanding The Attitudes And Behaviors Of Contractors, Cynthia J. Maahs

Psychology Theses & Dissertations

Previous research offers inconsistent findings with respect to attitude and behavior differences for contingent and permanent workers. The current study proposes the psychological contract as an explanatory framework for understanding differences between contractors and regular employees. The hypotheses examined attitudinal and behavioral measures: organizational commitment, job satisfaction, intent to quit, job performance, and organizational citizenship behaviors. The two components of the psychological contract (relational vs. transactional) were thought to impact differentially the outcome measures. Approximately 650 employees in a technology contracting organization completed an on-line survey designed to test the hypotheses. The two-factor structure of psychological contract was confirmed and …

Creating Individual Behavior Change Through 360-Degree Feedback: A Development Pipeline Perspective, Victoria Cole Stage

Psychology Theses & Dissertations

Ensuring that individuals develop new and more productive behaviors on the job is a challenge for many organizations and a focus of time, effort, and energy spent on programs to facilitate this change. This research was an effort to validate and utilize a framework for understanding how efforts toward individual development are restricted. To do this, I used a new 360-degree feedback instrument called “Time 2 Change” that measures self, manager, direct report, and peer/colleague perceptions of change in the individual. This instrument also measures the individual's perceptions of development enablers, in a framework called a Development Pipeline. As a …

The Relationship Among Disclosure, Internalized Homophobia, Religiosity, And Psychological Well-Being In A Lesbian Population, Sharon Lyn Clayman

Psychology Theses & Dissertations

This study investigated the relationship among disclosure, internalized homophobia, and religiosity in a lesbian population and how these three variables are related to psychological well-being in order to build upon the scant amount of empirical research on these variables in the lesbian psychological literature. A total of 679 women, 18 to 70 years old, and from all across the country were recruited via the internet to participate in a web-based survey. Participants completed a demographic questionnaire, the Lesbian Internalized Homophobia Scale (Szymanski & Chung, 2001), the Outness Inventory (Mohr & Fassinger, 2000), the Behavioral Self-Disclosure Questionnaire (Carroll & Gilroy, 2000), …

Acknowledgement Response And Interference Timing During The Processing Of Voice And Datalink Atc Commands, Matthew R. Risser

Psychology Theses & Dissertations

In aviation, effective communication between air traffic control (ATC) and pilots is critical to pilot performance and safety. Problems and limitations of current radio communications initiated the development of datalink technology. Datalink is a text system used to send messages between ATC and pilots. Although datalink was intended to reduce errors associated with radio communication, there are new concerns related to changes in information processing demands associated with executing speech and text ATC commands. In addition, the nature of responses differs between voice and datalink systems. In a voice environment, responses are immediate. However, time delays exist with datalink. These …

The Effects Of Operator Trust, Complacency Potential, And Task Complexity On Monitoring A Highly Reliable Automated System, Nathan R. Bailey

Psychology Theses & Dissertations

Technological advances have allowed for widespread implementation of automation in complex systems. However, the increase in quantity and complexity of advanced automated systems has raised a number of potential concerns including degraded monitoring skills. The present investigation consisted of two studies that assessed the impact of system reliability, complacency potential, monitoring complexity, operator trust, and system experience on monitoring performance. In both studies, participants monitored a simulated aviation display for failures while operating a manually controlled flight task. In addition, the second experiment assessed the ability of operators to detect a single automation failure over three experimental sessions. Results indicated …
