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 …


The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry Oct 2019

The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry

Psychology Theses & Dissertations

Interruptions are a common problem for attention and pose a threat to visual task performance. The Memory for Goals (MFG) theory suggests that strongly and accurately encoded cues can assist the ability to resume a primary task after an interruption (Altmann & Trafton, 2002). Encoded cues can undergo an activation decay during an interruption and become forgotten. Currently, there has been limited research on how visual interruptions affect cued recall within a dynamic environment. Thus, the goal of the present study was to examine the effect of cuing and task interruptions on change detection within dynamic scenes. Undergraduate students watched …


The Trojan Horse In Your Head: Cognitive Threats And How To Counter Them, Lora Pitman Jul 2019

The Trojan Horse In Your Head: Cognitive Threats And How To Counter Them, Lora Pitman

Graduate Program in International Studies Theses & Dissertations

Vulnerabilities of the human mind caused by the way it is designed to process information have always been exploited in warfare, since the dawn of humanity. History is marked with frequent use of deceits and manipulations over the centuries, with examples ranging from the use of the Trojan Horse to Facebook’s user-profiling. While largely used over time, these tactics, that I call cognitive threats, have not been collectively examined. I hypothesize that they pose a security issue to which prevention strategies on different levels could be successfully applied. The research questions that this study asks are what the characteristics of …


The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman Jul 2019

The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman

Psychology Theses & Dissertations

Because automation use is common in many domains, understanding how to design it to optimize human-automation system performance is vital. Well-calibrated trust ensures good performance when using imperfect automation. Two factors that may jointly affect trust calibration are automation transparency and perceived reliability. Transparency information that explains automated processes and analyses to the operator may help the operator choose appropriate times to shed task control to automation. Because operator trust is positively correlated with automation use, behaviors such as task shedding to automation can indicate the presence of trust. This study used a 2 (reliability; between) × 3 (transparency; within) …


Effects Of Focal On Driver Calibration Of Attention Maintenance Performance Using Normalized Difference And Brier Scores, James Richard Unverricht Jul 2019

Effects Of Focal On Driver Calibration Of Attention Maintenance Performance Using Normalized Difference And Brier Scores, James Richard Unverricht

Psychology Theses & Dissertations

Young drivers are specifically poor at maintaining attention to the forward roadway while driving. Additionally, drivers are poorly calibrated to their own abilities, often overestimating their driving skills. The current research examines the effect of FOCAL on a young driver’s calibration using two different measures, normalized difference scores and the Brier score. Thirty-six participants received either FOCAL or Placebo training program, immediately followed by driving simulator evaluation of their attention maintenance performance. In the evaluation drive, participants had driven through four scenarios in a driving simulator with their eyes tracked. Participants were asked to perform a mock visual search task …


Examining Validity Of Aha! Ratings As A Construct Of Insight, Ekaterina Y. Shurkova Apr 2019

Examining Validity Of Aha! Ratings As A Construct Of Insight, Ekaterina Y. Shurkova

Psychology Theses & Dissertations

Currently, there are two main views on insightful problem solving. Results of the studies supporting “business-as-usual” theory suggest that the processes involved in solving insight problems are the same as in analytical problem solving—slow, controlled, and effortful, while findings of the studies supporting the restructuring theory of insight suggest involvement of fast and automatic, one-trial-learning type of processes. The goal of the current study was to investigate the construct validity of the Aha! ratings, used in many studies as the measure of insight, by isolating its three components, effort, confidence, and suddenness, and examining their correlation with working memory span. …


Whose Drive Is It Anyway? Using Multiple Sequential Drives To Establish Patterns Of Learned Trust, Error Cost, And Non-Active Trust Repair While Considering Daytime And Nighttime Differences As A Proxy For Difficulty, Scott Mishler Apr 2019

Whose Drive Is It Anyway? Using Multiple Sequential Drives To Establish Patterns Of Learned Trust, Error Cost, And Non-Active Trust Repair While Considering Daytime And Nighttime Differences As A Proxy For Difficulty, Scott Mishler

Psychology Theses & Dissertations

Semi-autonomous driving is a complex task domain with a broad range of problems to consider. The human operator’s role in semi-autonomous driving is crucial because safety and performance depends on how the operator interacts with the system. Drive difficulty has not been extensively studied in automated driving systems and thus is not well understood. Additionally, few studies have studied trust development, decline, or repair over multiple drives for automated driving systems. The goal of this study was to test the effect of perceived driving difficulty on human trust in the automation and how trust is dynamically learned, reduced due to …


Estimating Cognitive Workload In An Interactive Virtual Reality Environment Using Electrophysiological And Kinematic Activity, Christoph Tremmel Apr 2019

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 …


Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran Apr 2019

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 …
