Estimating Cognitive Workload In An Interactive Virtual Reality Environment Using Eeg, Christoph Tremmel, Christain Herff, Tetsuya Sato, Krzysztof Rechowicz, Yusuke Yamani, Dean J. Krusienski

Electrical & Computer Engineering Faculty Publications

With the recent surge of affordable, high-performance virtual reality (VR) headsets, there is unlimited potential for applications ranging from education, to training, to entertainment, to fitness and beyond. As these interfaces continue to evolve, passive user-state monitoring can play a key role in expanding the immersive VR experience, and tracking activity for user well-being. By recording physiological signals such as the electroencephalogram (EEG) during use of a VR device, the user's interactions in the virtual environment could be adapted in real-time based on the user's cognitive state. Current VR headsets provide a logical, convenient, and unobtrusive framework for mounting EEG …

Workplace Bullying: A National Survey Of Dental Hygienists, Savannah Dawn Sundburg

Dental Hygiene Theses & Dissertations

Problem: Workplace bullying in health care affects career satisfaction, career longevity and patient outcomes. The purpose of this study was to determine if bullying was occurring in dental hygiene employment settings as well as its prevalence in a convenience sample of dental hygienists.

Methods: After IRB approval, 1200 subscribers to a professional dental hygiene journal were invited to participate. Employing the validated Negative Acts Questionnaire-Revised (NAQ-R), participants were asked to indicate how often they experienced 22 defined negative behaviors according to rate of occurrence (never, now and then or monthly, weekly or daily) over the past six months. Bullying was …

Intersectional Identities And Microaggressions: The Experience Of Transgender Females, Cory Daniel Gerwe

Counseling & Human Services Theses & Dissertations

Historically, attention given to privileged LGBT minorities such as white LGBT individuals, renders those who experience multiple minority identities as unacknowledged. There is a scarcity of research exploring the intersectional experiences of transgender individuals and how these experiences impact their mental health and well-being. For that reason, the intent of this study was to learn more about transgender females who hold additional minority statuses, their transition experiences, their circumstances, and the nature of their social environment. Specifically, I investigated trans female experiences of transitioning with a specific focus on the intersection of gender identity, race, socioeconomic status (SES), and age. …

The Bidirectionality Of Impulsivity And Alcohol Use: An Ecological Momentary Examination Among Emerging Adults, Amy L. Stamates

Psychology Theses & Dissertations

Impulsivity is a robust risk factor for alcohol use among emerging adults (i.e., 18 to 25), but significant gaps remain in our understanding of the way that impulsivity relates to alcohol harms. Most prior research has been limited to between-level differences; thus, within-person variability in impulsivity at the momentary level and its bidirectional association with alcohol use has not been examined. Consequently, the present research used a 14-day ecological momentary assessment (EMA) design to: (1) determine momentary impulsivity as a predictor of subsequent alcohol use and problems; (2) examine the influence of alcohol use on subsequent impulsivity; (3) test socio-cognitive …

Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran

Psychology Theses & Dissertations

The purpose of this study was to test Wickens’ Multiple Resource Theory (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of transferring rings from one peg to another and a low workload task that consisted of grasping and placing large pencil erasers in a bowl. It was predicted that the visual-spatial secondary task would be more sensitive when paired with the laparoscopic primary task than the auditory analog. Findings …
