Investigating The Relationship Between Binocular Disparity, Viewer Discomfort, And Depth Task Performance On Stereoscopic 3d Displays, John Paul Mcintire

Browse all Theses and Dissertations

Stereoscopic 3D (S3D) displays offer the capability to enhance user performance on a variety of depth tasks. However, the benefit derived from viewing S3D depends in part on the magnitude of binocular disparity that is displayed. Surprisingly few studies have directly investigated the relationship between disparity and depth task performance. The studies that have been conducted suggest that a minimum amount of disparity (10-50 arc min) may be needed to improve performance over conditions in which no S3D is present, but it is unclear the extent to which performance might improve with increases in disparity beyond this range.

Challenge Accepted: Self-Enhancement Through The Pursuit Of Difficulty, Julie Anne Steinke

Browse all Theses and Dissertations

Individual resilience is popular topic whereby researchers attempt to identify characteristics of individuals who react positively to stress. However, such research uses a reactionary approach, attempting to characterize successful individuals after they experience adversity and does not explain why some individuals proactively seek out challenging circumstances. Pursuing challenge is a new construct that explains why individuals proactively increase stress as a strategic mechanism for developmental purposes. I developed and validated a measurement tool for pursuing challenge in multiple studies. Additionally, I explored relationships between pursuing challenge and similar constructs (e.g., grit, proactive personality, and self-efficacy), as well as the extent …

The Effectiveness Of Warnings At Reducing The Prevalence Of Insufficient Effort Responding, Caitlin E. Blackmore

Browse all Theses and Dissertations

Unmotivated participants who fail to devote sufficient effort to their survey responses can influence the quality of self-report data. The majority of the published literature on this topic has concerned techniques for detecting insufficient effort responding (IER), whereas little attention has been given to developing effective procedures for preventing IER. There are numerous advantages to preventing IER, one of which is that discarding data is unnecessary. The current study examined the effects of a warning manipulation on the prevalence of IER and the quality of the resulting data. Statistically significant differences between conditions on four of the IER detection measures …

Rater Characteristics In Performance Evaluation Accuracy, Shotaro Hakoyama

Browse all Theses and Dissertations

The current study examined how various rater-level variables are related to performance ratings. Student participants watched a series of video clips depicting high, medium, and low levels of employee work performance. The participants then rated the performance of the employee depicted in the video on a graphic rating scale. The rater level variables examined for the current study included rater goals, cognitive ability, conscientiousness, and agreeableness. The results indicated that focusing the on the strength of the employee (strength goal) was associated with rating elevation and that rater conscientiousness was associated with rating deflation. Strength goal, conscientiousness, agreeableness, and cognitive …

Alternative Indices Of Performance: An Exploration Of Eye Gaze Metrics In A Visual Puzzle Task, Sheldon M. Russell

Browse all Theses and Dissertations

Of interest to the U.S. Air Force is the ability to develop and characterize the level of workload that operators are under at any given point. When an operator's cognitive resources exceed demands, a 'red line' of performance may be crossed after which performance breaks down. What is needed is an estimate of operator state; a 'dipstick' for the operator in order to assess the level of 'resources' available, in order to avoid performance problems. Traditional approaches use secondary tasks (e.g., mental arithmetic) or secondary physiological measures (e.g., heart rate variability) for state assessment. However, the current work was motivated …

Goal Orientations And Self-Efficacy Interactions On Self-Set Goal Level, Truman Joseph Gore

Browse all Theses and Dissertations

The current study examined the interactive effects of goal orientations (the tendencies of an individual to set specific types of goals, i.e., learning or performance goals), and self-efficacy (an evaluation of one's own competence on a task) on self-set goal levels and performance in an academic context. Past research has found that learning goal orientation and self-efficacy are both positively related to the difficulty of self-selected goals and to performance whereas avoid-performance goal orientation is negatively associated with both the difficulty of self-set goals and performance. The current study found that learning goal orientation and self-efficacy were positively related to …

Fear Of Discrimination And Leveraging Of Leadership Experience In Individuals Of Lgbtq Organizations, Megan Brianne Morris

Browse all Theses and Dissertations

Awareness of the Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) community has exposed these individuals to unequal treatment in the workplace. One area where this mistreatment occurs is in the job application process. As a result, it is important to examine the job seeking behaviors of the LGBTQ community that are associated with this process. Student leaders of LGBTQ-focused groups face a unique challenge in the application process in regard to whether they should include their leadership experience on their resume, possibly exposing themselves to discrimination and bias. Only one study, to current knowledge, has focused on resume construction behavior …

Psychological Contract Breach By The Supervisor, Darrell Scott Kelly

Browse all Theses and Dissertations

My study examined the effect of psychological contract breach by a supervisor on employee job outcomes (OCBs, CWBs, and job satisfaction). Also, I tested the moderating effects of the quality of a relationship between an employee and his or her supervisor, and an employee and his or her organization, on the psychological contract breach - job outcomes relationship. I found minimal support that employees distinguish between their supervisors and their organizations when assessing psychological contract breach. Also, I found no support that relationship quality had any moderating effects. However, I did find that LMX-I and LMX-O might measure the same …

Using Differential Functioning Of Items And Tests (Dfit) To Examine Targeted Differential Item Functioning, Erin L. O'Brien

Browse all Theses and Dissertations

Current studies of differential item functioning (DIF) look at look at how groups differ in responding to items across an entire trait continuum. This is important for detecting the presence of consistent patterns of responses across items between groups of people. Current tests of DIF are limited in that they only detect differences between groups across all levels of the trait. However, selection decisions are usually made within specific ranges of trait levels. The purpose of this research was to determine if restricting theta values in an existing framework would be better at detecting DIF as current methods for restricted …

Shared Leadership In Team-Based Learning Classroom Teams And Its Relationship To Decision Quality, Elizabeth J. Peyton

Browse all Theses and Dissertations

Team-based learning (TBL) is an increasingly popular teaching technique within healthcare education. However, much remains unknown about the processes underlying its effectiveness. I examined shared leadership behaviors in TBL teams and their relationship to academic performance and team decision quality both in the classroom and in an applied setting. To examine these relationships, I used round-robin peer evaluations that I analyzed using the Social Relations Model. Results failed to support my hypotheses. However, my study raised several issues that future researchers should consider: the relationship between shared and vertical leadership, proper conceptualization of Followership, using Social Relations Model estimates versus …

Cued Visual Search And Multisensory Enhancement, Jordan Haggit

Browse all Theses and Dissertations

Previous research has been divided on whether or not multisensory cues can speed visual search relative to their component unisensory cues alone. Some studies (e.g., Mateo et al., 2012) found reaction times for multisensory cues were not faster than the RT of the faster component unisensory cue alone. Other studies (e.g., Oskarsson et al., 2012) found the multisensory cue to be faster than either unisensory cue alone (i.e., multisensory enhancement). This study aimed to determine whether the relative effectiveness match between auditory and tactile cues affects multisensory enhancement on a visual search task. In Experiment 1 we estimated for each …
