Estimating Cognitive Workload In An Interactive Virtual Reality Environment Using Electrophysiological And Kinematic Activity, Christoph Tremmel

Biomedical Engineering Theses & Dissertations

As virtual reality (VR) technology continues to gain prominence in commercial, educational, recreational and research applications, there is increasing interest in incorporating physiological sensors in VR devices for passive user-state monitoring to eventually increase the sense of immersion. By recording physiological signals such as the electroencephalogram (EEG), electromyography (EMG) or kinematic parameters during the 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. This dissertation evaluates the feasibility of passively monitoring cognitive workload via electrophysiological and kinematic activity while performing a classical n-back task in …

Self-Regulated Learning Strategies Vs Evidence-Based Study Strategies, Wanda Brooks, Linda Bol

College of Education & Professional Studies (Darden) Posters

There is a growing concern about students entering college only to drop out or change majors after a semester or more of study. There are multiple reasons for this including personal reasons that may have nothing to do with academics, of course, but sometimes students switch to different majors because they feel that their original choice is too difficult after not doing well in the required introductory courses. Training in self-regulated learning (SRL) strategies may enable students to gain the skills necessary (e.g., making goals, planning, organization) to succeed in gateway courses that have a minimum grade requirement. These behaviors …

Exploring The Influence Of Maternity Leave On Maternal Child Bonding, Amber Wilson, Kathie Zimbro, Carolyn Rutledge

College of Health Sciences Posters

PROBLEM: Approximately half of the women of child-bearing age are eligible for Family Medical Leave Act (FMLA). However, taking unpaid maternity leave may place a significant financial burden on any family. Lack of maternity leave, or shorter durations of maternity leave is listed as a significant barrier to breastfeeding, yet there have been no changes implemented to improve that since FMLA was signed into action in 1993. PURPOSE: The purpose of this study is to explore relationships between participant characteristics, breastfeeding initiation and duration, maternity leave, motherhood, postpartum mood disorders (anxiety/depression), and maternal child bonding and attachment. EBP QUESTIONS: (1) …

The Impact Of Mandatory Substance Abuse Counselor Reporting Requirements On Child Maltreatment Reporting Outcomes, Bilgé Yilmaz, Kelli E. Will, Andrew D. Plunk

College of Sciences Posters

Child maltreatment takes on numerous forms, including physical abuse, psychological abuse, sexual abuse, and neglect, and affects an estimated 38% of children in the United States (U.S.). Due to the deleterious effects of maltreatment, 48 states mandate most health professionals to report suspected abuse and neglect. Yet, only 14 states specifically require substance abuse counselors to report suspected abuse and neglect. Substance abuse is commonly implicated in maltreatment cases, with an estimated 40 to 70 percent involving alcohol or drug use among perpetrators, which points to the importance of examining the association between substance abuse counselor reporting and the outcome …

A Path Analysis Of The Mediating Role Of Flood Risk Perceptions, Donta Council

College of Business (Strome) Posters

The purpose of this research is to examine the multiple relationships that explain household adaptive behaviors, and if (and how) risk perceptions play a mediating role in these relationships. Given the shift in transferring risks from flood risk governance structures to households, there is a renewed interest in promoting private adaptive behavior amongst households that are vulnerable to flood impacts. While the literature purports the claim that flood risk perceptions rarely account for the variance explained in statistically modeling for household adaptive behaviors, this study will analyze an integrated conceptual framework that explores the mediating role of risk perceptions. The …

Muted Groups Theory In Human Trafficking, Amy Matzke-Fawcett

College of Arts and Letters Posters

“Human trafficking,” defined as, “a commercial . . . act . . . the result of force, threats of force, fraud, coercion or any combination of such means” (President’s Interagency Task Force, 2016, p. 2) is a problem in the United States and internationally. Human trafficking, defined by the same task force, is a crime that includes sex trafficking, child sex trafficking, and labor trafficking which consists of bonded labor, debt bondage, domestic servitude, forced child labor, and in some cases, the recruitment or use of child soldiers. Although it is important to raise societal awareness of this crime, it …

Elementary Preservice Teachers’ Perceptions Of Modeling As A Tool For Instruction, Ginger S. Watson, Mary Enderson

Teaching & Learning Faculty Publications

As the standards movement continues to gain momentum in U.S. schools, preservice and in-service teachers need greater knowledge in mathematical modeling to engage PK-12 students in such practices. This case-based research study investigated the perceptions and understandings of modeling for 76 entry-level, preservice elementary teachers enrolled in a mathematics methods course at a mid-Atlantic university. Participants were prompted to define modeling and its application to classroom instruction through open-response questions administered in an online survey. A case-based, phenomenological method was used to code and analyze responses. Most preservice teachers expressed a very limited definition or understanding of modeling or how …

Reimagining Medical Education In The Age Of Ai, Steven A. Wartman, C. Donald Combs

Computational Modeling & Simulation Engineering Faculty Publications

Available medical knowledge exceeds the organizing capacity of the human mind, yet medical education remains based on information acquisition and application. Complicating this information overload crisis among learners is the fact that physicians' skill sets now must include collaborating with and managing artificial intelligence (AI) applications that aggregate big data, generate diagnostic and treatment recommendations, and assign confidence ratings to those recommendations. Thus, an overhaul of medical school curricula is due and should focus on knowledge management (rather than information acquisition), effective use of AI, improved communication, and empathy cultivation.

Lexical-Level Predictors Of Reading Comprehension In Third Grade: Is Spelling A Unique Contributor?, Kimberly A. Murphy, Laura M. Justice

Purpose:

Considerable research effort has focused on understanding reading comprehension and reading comprehension difficulties. The purpose of this correlational study was to add to the small but growing body of literature on the role that spelling may play in reading comprehension, by investigating the full range of lexical-level literacy skills and whether spelling makes a unique contribution. This study also explored whether these relations vary with the spelling scoring metric.

Method:

Data were collected from 63 children attending Grade 3 in a Midwestern state. In addition to measuring reading comprehension, word recognition, and vocabulary, 4 spelling scoring metrics were examined: …

The Disparity In Mental Health Between Two Generations Of Internal Migrants (Ims) In China: Evidence From A Nationwide Cross-Sectional Study, Wen Chen, Qi Zhang, Andre M.N. Renzaho, Li Ling

Community & Environmental Health Faculty Publications

Background: Internal migrants (IMs) are a large, vulnerable population in China and are mostly driven by national economic reform. IMs who were born before and after 1980, when the general social and economic reform began to appear in China, are considered to be two separate generations. The generational differences in mental health across IMs remain undocumented. In this study, the intergenerational disparity in IMs’ mental health, using data from a national cross-sectional study, was assessed. Methods: Cross-sectional data from the “National Internal Migrant Dynamic Monitoring Survey 2014” were used. IMs were divided into the “old” or “new” generation, based on …

Experimental Investigation On The Effects Of Website Aesthetics On User Performance In Different Virtual Tasks, Meinald T. Thielsch, Russell Haines, Leonie Flacke

Information Technology & Decision Sciences Faculty Publications

In Human-Computer Interaction research, the positive effect of aesthetics on users' subjective impressions and reactions is well-accepted. However, results regarding the influence of interface aesthetics on a user's individual performance as an objective outcome are very mixed, yet of urgent interest due to the proceeding of digitalization. In this web-based experiment (N = 331), the effect of interface aesthetics on individual performance considering three different types of tasks (search, creative, and transfer tasks) is investigated. The tasks were presented on an either aesthetic or unaesthetic website, which differed significantly in subjective aesthetics. Goal orientation (learning versus performance goals) was included …
