The Influence Of Flow On Standard And Adaptive Performance In Teams, Jennifer N. Baumgartner

Browse all Theses and Dissertations

The purpose of this study was to examine flow as it relates to different types of performance in teams. Participants (N = 165) in teams of five engaged in an airport simulation that included an unforeseen change during the second session. Flow was expected to be positively correlated with standard and adaptive performance and predict performance along with cognitive ability and personality. Positive affect was expected to mediate the relationship between flow and performance. Flow was positively correlated with the number of aircraft departed under standard conditions, negatively correlated with aircraft departed under adaptive conditions, and positively correlated with subjective …

Not All Forms Of Misbehavior Are Created Equal: Perpetrator Personality And Differential Relationships With Cwbs, Caleb Braxton Bragg

Browse all Theses and Dissertations

Most research has lumped counterproductive work behaviors into a single or a few categories. The present study, however, used dominance analysis to examine whether aggression, industriousness, dishonesty and self-control had differential predictive relationships with the Gruys and Sacket (2003) 11-Factor CWB model. I hypothesized that various CWBs would be differentially predicted by various personality traits, and that those predictive relationships would be moderated by self-control. The results indicated all CWBs are not created equal and should not be lumped into a single all-inclusive category. Counterproductive work behaviors are multidimensional, with unique predictors and covariates, and are best understood and predicted …

Reasonable Reasoner: The Influence Of Intervention Strategy, System Parameters And Their Representation On Causal Understanding, Beth Cristina Bullemer

Browse all Theses and Dissertations

The following study assessed how contingency and delay influence people's reasoning strategy and outcomes after interacting with a representation of a discrete and continuous system environment, in the context of controlling hypertension. The related causal reasoning and system dynamics research adopt different measurement paradigms and employ different system dynamics, making it difficult to resolve the empirical findings. Specifically, the causal reasoning literature has traditionally considered systems in which previous inputs do not influence future outcomes (e.g., a discrete system condition) while the system dynamics literature removes this constraint (e.g., a continuous system condition). Also, the system dynamics literature has focused …

Individual Differences In The Use Of Remote Vision Stereoscopic Displays, Marc Winterbottom

Browse all Theses and Dissertations

With the introduction of the next generation of aerial refueling tankers, such as the KC-46, boom operators will use relatively recently developed indirect view stereo displays in place of direct view crew stations. Existing vision standards for boom operators were developed during the 1950s and may not be adequate for medical screening for KC-46 boom operators. Mild anomalies in binocular alignment, currently allowed by USAF vision standards, may permit stereopsis, but may also predispose those individuals to visual complaints such as eye-strain or headaches when viewing stereoscopic displays.

The purpose of this research was to measure individual differences in performance …

Cognitive Analysis Of Multi-Sensor Information, Elizabeth Lynn Fox

Browse all Theses and Dissertations

Multispectral imagery can supply an observer with different components of information to, in combination, lead to critical decisions. Human observers can be presented with two fusion techniques: 1) cognitive fusion presents the two sensor images within 5 degrees of visual angle and 2) algorithmic fusion aims to enhance image quality by combining relevant information from two individual sensor images into one composite image. Researchers have used methods such as comparing performance across different algorithms or comparing algorithmic fusion to a single-sensor image. However, cognitive fusion is a technique that provides all of the sensor information and, if utilized efficiently, may …

Once Careless, Always Careless? Temporal And Situational Stability Of Insufficient Effort Responding (Ier), Kelly Ann Camus

Browse all Theses and Dissertations

In the current paper, I examined insufficient effort responding (IER) as a substantive construct rather than as a methodological nuisance as other researchers have done. Specifically, I focused on the relationship between personality traits and IER and the temporal and situational stability of IER. I hypothesized that agreeableness, conscientiousness, openness, and extraversion would be negatively associated with IER and that neuroticism would be positively related to IER. Also, I predicted that the extent to which a given participant engages in IER would be relatively stable across time and across tasks. The current sample (N = 288) consisted of students from …

Chat Communication In A Command And Control Environment: How Does It Help?, April M. Courtice

Browse all Theses and Dissertations

Military command and control (C2) teams are often faced with difficult, complex, and distributed operations amidst the fog and friction of war. To deal with this uncertainty, teams rely on clear and effective communication to coordinate their actions; two current conduits for communication in distributed military teams include voice and chat. Chat communication is regarded by many in the C2 world as the premier method of communicating with the power to lessen some of the traffic and disturbances of current voice communication, and its usage continues to exponentially increase. Despite this operational view, countless laboratory studies have demonstrated detrimental effects …

Effect Of Localized Temperature Change On Vigilance Performance, Jessica Spencer Pack

Browse all Theses and Dissertations

This study examined the influence of localized temperature change on vigilance performance. Additionally, the effect of stressor appraisals on the relationship between localized temperature change and vigilance performance was investigated. A total of 36 male and female participants between the ages of 18 and 45 completed a stressor appraisal scale before completing a 40-minute simulated air traffic control vigilance task. Depending on the condition, either a hot, cold, or neutral temperature change was induced using a thermoelectric pad and blanket 20 minutes into the vigilance task. Although localized temperature change did not have a significant effect on vigilance performance 25-30 …

A Study Of Exercise: Intentions And Behavior, Michael Raymond Hoepf

Browse all Theses and Dissertations

Health concerns associated with obesity are becoming an increasingly large societal problem. Engaging in physical exercise is one effective way to combat obesity, but most people do not exercise enough to derive significant health benefits. In order to increase participation in exercise activities, it is first necessary to have a good understanding of why people are not exercising. The current research builds on prior research by investigating the proposition that conflict from work, family, and school roles can reduce time spent exercising. To accomplish this goal, I created exercise conflict scales by taking existing items from the work-family conflict literature …

Bridging The Gap: Exploring The Need For Better System Representations In Higher Education, Corinne P. Wright

Browse all Theses and Dissertations

Higher education constitutes a sociotechnical system. Some students enter with cultural experiences that support the new endeavor whereas others are woefully under-supported. Student preparedness often is tightly coupled with student background. Some ethnic minorities and students from impoverished backgrounds enter the university setting with a high risk of not persisting or completing their higher education pursuits (e.g., Kuh, Kinzie, Bridges, & Hayek, 2007). Traditional conceptualizations of risk identify immutable factors, such as SES, with little opportunity for immediate mitigation. Traditional interventions to mitigate risk include either fitting the student to the system (e.g., Tinto, 1993) or fitting the system to …

Detecting Structure In Activity Sequences: Exploring The Hot Hand Phenomenon, Taleri Lynn Hammack

Browse all Theses and Dissertations

Can humans discriminate whether strings of events (e.g., shooting success in basketball) were generated by a random or constrained process (e.g., hot and cold streaks)? Conventional wisdom suggests that humans are not good at this discrimination. Following from Cooper, Hammack, Lemasters, and Flach (2014), a series of Monte Carlo simulations and an empirical experiment examined the abilities of both humans and statistical tests (Wald-Wolfowitz Runs Test and 1/f) to detect specific constraints that are representative of plausible factors that might influence the performance of athletes (e.g., learning, non-stationary task constraints). Using a performance/success dependent learning constraint that was calibrated to …
