Effects Of Visual Interaction Methods On Simulated Unmanned Aircraft Operator Situational Awareness, Brent A. Terwilliger

Publications

The limited field of view of static egocentric visual displays employed in unmanned aircraft controls introduces the soda straw effect on operators, which significantly affects their ability to capture and maintain situational awareness by not depicting peripheral visual data. The problem with insufficient operator situational awareness is the resulting increased potential for error and oversight during operation of unmanned aircraft, leading to accidents and mishaps costing United States taxpayers between $4 million to $54 million per year. The purpose of this quantitative experimental completely randomized design study was to examine and compare use of dynamic eyepoint to static visual interaction …

Effects Of Childhood Family Dynamics On Body Dissatisfaction In Adulthood, Adrienne F. Kerbs

EWU Masters Thesis Collection

"Past research has identified many singular components of family dynamics that affect body dissatisfaction in adulthood, but have not studied the effects of many different family factors simultaneously. The aim of the current study was to investigate the effects of multiple early family dynamics on body dissatisfaction in adulthood using a sample of female college students. It was expected that the nature of parental bonding, parental comments, and lack of parental acceptance during childhood would have negative effects on body image in adulthood. A sample of female college students completed self-report questionnaires about their parents from the perspective of when …

The Effect Of Improvisations And Observations On Standardized Patient Encounters, Subjective Workload And Stress, Elizabeth T. Newlin-Canzone

Psychology Theses & Dissertations

Standardized patients (SPs) are people trained to present a medical case for teaching and assessing medical students and they simultaneously perform several demanding tasks including portraying the patient, assessing the learner, and providing feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved undergraduates interviewing for a job. Type of interview (rote and improvisational) and type of observation (passive and active) were manipulated within groups. Based on theories of attention …

Comics As A Cognitive Training Medium For Expert Decision Making, Amber Nalu

Psychology Theses & Dissertations

Experts such as military commanders must make decisions quickly and under deadly conditions. A variety of cognitive training media exist, from Powerpoint to virtual reality (VR) simulations; however, there are alternative media that have not yet been comprehensively studied for expert decision making training. In this study, the researcher has examined the use of comics as an alternative to current cognitive training media. In Experiment 1, naval submariners were shown a text-based medium or comic strip and asked to make a decision about the scenario after viewing. The scenario was derived from a situation that submariners were somewhat familiar with …

What Are We Studying? Student Jurors, Community Jurors, And Construct Validity, Stacie R. Keller, Richard L. Weiner

Department of Psychology: Faculty Publications

Jury researchers have long been concerned about the generalizability of results from experiments that utilize undergraduate students as mock jurors. The current experiment examined the differences between 120 students (55 males and 65 females, mean age = 20 years) and 99 community members (49 males and 50 females, mean age = 42 years) in culpability evaluations for homicide and sexual assault cases. Explicit attitude measures served as indicators of bias for sexual assault, defendant, and homicide adjudication. Results revealed that student and community participants showed different biases on these general explicit attitude measures and these differences manifested in judgments of …

Tools For Evaluating Team Performance In Simulation-Based Training, Michael A. Rosen, Sallie J. Weaver, Elizabeth H. Lazzara, Eduardo Salas, Teresa Wu, Salvatore Silvestri, Nicola Schiebel, Sandra Almeida, Heidi B. King

Publications

Teamwork training constitutes one of the core approaches for moving healthcare systems toward increased levels of quality and safety, and simulation provides a powerful method of delivering this training, especially for face-paced and dynamic specialty areas such as Emergency Medicine. Team performance measurement and evaluation plays an integral role in ensuring that simulation-based training for teams (SBTT) is systematic and effective. However, this component of SBTT systems is overlooked frequently. This article addresses this gap by providing a review and practical introduction to the process of developing and implementing evaluation systems in SBTT. First, an overview of team performance evaluation …

The Impeding Role Of Initial Unrealistic Goal-Setting On Training Performance: Identifying Underpinning Self-Regulatory Processes And Solutions, Robert C. Brusso

Psychology Theses & Dissertations

The importance of goal-setting within training for enhancing performance has been touted in the literature. Goal-setting theory suggests that setting a moderately difficult, specific goal results in a modest goal-performance discrepancy between the trainee's goal and actual performance level. Such a discrepancy has been found to enhance subsequent performance, as the trainee will employ greater effort and task engagement to resolve the discrepancy. However, research has also shown that the motivating effect of a discrepancy will reverse with repeated feedback indicating that one's performance has fallen short of the desired goal. To date, no prior research has examined the effect …

An Investigation Of Interpersonal Disruptions And Secondary Traumatic Stress Among Mental Health Therapists, Rachael Ann Robinson-Keilig

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Mental health therapists who work with victims of trauma are often exposed to vivid descriptions of traumatic events and strong emotional expressions from their clients. Research within the last fifteen years has started to explore the impact of this indirect form of trauma exposure on therapists who treat trauma clients.

The purpose of this study was to explore the prevalence of interpersonal and sexual disruptions as symptoms of secondary traumatic stress/vicarious trauma among practicing mental health therapists, to understand how various therapist characteristics predict interpersonal and sexual disruptions, and to explore the role that gender and prior trauma history play …

Effect Of Time Pressure And Task Uncertainty On Human Operator Performance And Workload For Autonomous Aerial Vehicle Missions, Trevor Petersen

Master's Theses - Daytona Beach

Unmanned aircraft systems (UAS) are being utilized at an increasing rate for a number of military applications. The potential for their use in the national airspace is also of interest to the Federal Aviation Administration, but there are some concerns about the safety of flying unmanned aircraft. The role of a UAS operator differs from that of a pilot in a manned aircraft, and this new role creates a need for a shift in interface and task design in order to take advantage of the full potential of these systems. This study examined the effect of time pressure and task …

Integrating Situation Awareness Assessment Into Test And Evaluation, Cheryl A. Bolstad, Haydee Maria Cuevas

Publications

To guarantee the success if network- centric operations, warfighters need the ability to extract and share critical task-relevant information to develop and maintain the situation awareness that is so critical far effective team performance. As such, the design of emerging technologies and systems must adopt a "user-centric" approach, with consideration for human information processing capabilities and limitations. In turn, to ensure that these technologies and systems are meeting their design objectives, test and evaluation must similarly be expanded to include metrics that assess how well system features and functions are supporting critical human cognitive processes such as situation awareness and …
