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 …

Self-Concept Clarity And The Bodily Self: Malleability Across Modalities, Sonia A. Krol, Rémi Thériault, Jay A. Olson, Amir Raz, Jennifer A. Bartz

Psychology Faculty Articles and Research

The self has fascinated scholars for centuries. Although theory suggests that the self-concept (cognitive self-understanding) and bodily self (pre-reflective awareness of one’s body) are related, little work has examined this notion. To this end, in Study 1, participants reported on self-concept clarity (SCC) and completed the rubber hand illusion (RHI), a paradigm in which synchronous (vs. asynchronous) stimulation between a prosthetic hand and one’s own hand leads one to “embody” the prosthetic hand. Whereas participants were equally susceptible to the RHI during synchronous stroking, low-SCC individuals were more vulnerable to the illusion during asynchronous stroking, when the effect is unwarranted. …

The Effects Of Historical Alcohol Use On Neuropsychological Functioning In Older Adults Following A Traumatic Brain Injury, Ryan Sever

Dissertations

The present study aimed to determine the effects of alcohol abuse and dependence in long term functioning of older adults who have experienced a moderate to severe traumatic brain injury. The research question being answered in the current study was if a history of alcohol abuse or dependence would worsen neuropsychological functioning in older adults who experienced at least one moderate to severe traumatic brain injury. Participants of the study were selected from the more extensive database provided by the Brain Aging in Vietnam War Veterans (DOD-ADNI) database. All participants were Vietnam War veterans between the ages of 61 and …

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 …

Heroic Consciousness, Scott T. Allison

Heroism Science

This article describes heroic consciousness – how heroes perceive, experience, and think about the world. I describe the transformation of consciousness from its pre-heroic state to its heroic state. Pre-heroic consciousness is characterized by nescient and maladaptive thinking, dualism, separation, mono-rationality, and a naïve sense of empowerment. Heroic consciousness is exemplified by nondualism, unity, transrationality, and the wisdom of tempered empowerment. Heroic consciousness is achieved via three routes: (1) traversing the hero’s journey, (2) effective use of specific spiritual practices, and/or (3) participation in hero training programs. I discuss the implications of heroic consciousness for individual and global well-being.

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober

Dissertations, Theses, and Capstone Projects

Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

Memory-Guided Selective Attention: An Instance Theory Of Automatic Attentional Control, Nicholaus Paul Brosowsky

Dissertations, Theses, and Capstone Projects

Cognitive control enables flexible goal-directed behavior via attention and action selection processes that prioritize goal-relevant over irrelevant information. These processes allow us to behave flexibly in the face of contradicting or ambiguous information and update behavior in response to the changing environment. Furthermore, they are thought to be in direct opposition to learned, automatic processing in that they enable us to disregard learned behaviors when they are inconsistent with our current goals. The strict dichotomy between stimulus-driven and goal-driven influences, however, has downplayed the role of memory in guiding attention. The position forwarded in this thesis is that a memory-based …

The Use Of Infographics To Assess Context Processing, Beliz Hazan

Dissertations, Theses, and Capstone Projects

Among high-order cognitive functions is the use of context to enhance comprehension of language or visual scenes. Although use of context is known to be impaired in certain clinical populations (e.g., schizophrenia), no existing test adequately assesses this construct. To fill this gap, we developed and attempted to validate a test of context use that employed Infographics (information graphics), which requires the use of context to interpret visual displays. The primary hypothesis was that interpreting Infographics would be sensitive to context processing. We further hypothesized that different levels of cognitive processing (requiring basic perceptual, real-world application, or verbal reasoning), as …

The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses

Dissertations, Theses, and Capstone Projects

The three-stage model of distraction asserts that when we are presented with salient but task-irrelevant information, our sensory systems first detect the distracting stimulus by way of sensory memory buffers, which is indicated electrophysiologically by the mismatch negativity (MMN). Following detection, attentional resources are involuntarily allocated towards the processing of the distraction, as represented by the P3a. Finally, attentional resources are shifted away from the distracting stimulus and returned to the task-relevant information, as indicated by the reorienting negativity (RON). A great deal of research has focused on this last step in the model, largely centering around defining the mechanisms …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

The Role Of Eyewitness Confidence And Prosecution/Defense Presentation In How Facial Composites Shape Juror Decision-Making, Rebecca E. Singh

Student Theses

Eyewitness testimony has been found to be an unreliable form of evidence (Loftus, Miller & Burns, 1978; Oswald & Coleman, 2007; Wells & Hasel, 2007; Loftus & Greenspan, 2017; Jaross, 2018; Wade, Nash, & Lindsay, 2018; Wixted, Mickes, & Fisher, 2018). Yet, this evidence is still used in the courts today, and, in fact, is perceived by jurors as important and compelling in comparison to other case factors (e.g., character evidence, physical evidence; Topp-Manriquez, McQuiston, & Malpass, 2014; Kabzińska, 2015). Additionally, eyewitnesses are sometimes requested to help create a facial composite of the suspect and, critically, these composites are then …

The Effect Of Peer Collaboration On Kinematic Problem Solving, Alyssa Deronda

Seton Hall University Dissertations and Theses (ETDs)

Kinematic problems, a type of physics problem that involves object motion, pose a challenge for adults (Caramazza, McCloskey, & Green, 1981; Kozhevnikov, Motes, & Hegarty, 2007; McCloskey, 1983b; McCloskey, Washburn, & Felch, 1983). Adults often incorrectly predict the path of a moving object despite having prior experience with moving objects or formal physics education (Caramazza et al., 1981; Kaiser, Jonides, & Alexander, 1986). One way to improve kinematic problem solving may be through peer collaboration. Working together with a partner to solve a problem allows both people to help each other remember important parts of a complex problem and discuss …

Firearm Availability And Storage Practices Among Military Personnel Who Have Thought About Suicide, Craig J. Bryan, Annabelle O. Bryan, Michael D. Anestis, Lauren Khazem, Julia Harris, Alexis May, Cynthia Thomsen

Faculty Publications

More than 60% of US military suicides occur at home and involve a firearm. Nearly all military firearm suicides (95%) involve a personally owned firearm. Nonmilitary data indicate that the risk of suicide is 6 times higher in households with a firearm, although this risk may be reduced if the firearms are kept unloaded and/or locked. Because attempts using firearms have very high fatality rates, safe firearm storage practices could be an important component of comprehensive suicide prevention in the military. This study examined associations of firearm ownership and storage practices with suicidal thoughts and behaviors among military personnel.

Impact Baseline Composite Score Differences Among Student Athletes, Kerry Schutte

Electronic Theses and Dissertations

The ImPACT aims to measure neurocognitive functioning in student athletes. Many schools administer preseason ImPACT assessments to determine athletes’ baseline functioning. Follow-up ImPACT assessments are administered to athletes who sustain concussions to compare their pre- and post-injury functioning. Normative data may be used in place of individualized baseline scores if athletes were not administered baseline assessments. At the inception of this study, normative datasets consisted of scores from typically developing athletes. However, research suggests athletes of varying gender and exceptionality statuses perform differently on baseline ImPACT assessments. In particular, differences were found among male and female athletes as well as …

Exploring Innovation And Behavioral Flexibility In African Lions (Panthera Leo) And Snow Leopards (Panthera Uncia), Victoria L. O'Connor

Theses and Dissertations

Intelligence may have evolved to help animals problem-solve in their physical and/or social environments, which enables them to cope with changes in their environments. Humans can reduce wildlife conflict by understanding how species that face harsh environments assess a situation and alter their behavior. Tests for cognitive behavior aim to formulate clear behavioral criteria for inferring an animal’s mental processes. We designed a custom multi-access puzzle box (MAB) to present a simple and effective behavioral test for exploring innovation in two species, African lions (Panthera leo) and snow leopards (Panthera uncia). Despite being vastly underrepresented in …

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

Arousal And Anxiety Level Influences On Golf Putting Performance, Chloe Paulsen, Ryan M. Yoder

Honors Theses

Arousal levels can help and hinder performance in various sports and many athletes manipulate arousal levels during practice or competitions. Professional golfers typically putt in complete silence but studies have shown that stimulus can help performance. Twelve participants completed general and sport anxiety questionnaires before completing 3 golf putts at a target under 30 seconds with a music stimulus for each group. Music stimulus had an affect on the moderate arousal level groups showing the best performance with the slowest time to complete the putting task. This shows that putting may be performed better with moderate auditory arousal to produce …

Context And Regulation Of Homeschooling: Issues, Evidence, And Assessment Practices, Janet F. Carlson

Buros Center: Professional Staff Publications

The article discusses salient factors that influence the current context within which homeschooling occurs. Individual states have applied various approaches to establish regulations that both preserve the rights of homeschooling parents and fulfill the state’s obligation to ensure that its residents receive the education to which they are constitutionally entitled. Case and ethnographic studies or research involving small and selected samples often appear in outlets associated with homeschool advocacy groups or in outlets that are not mainstream. The paucity of empirical evidence derived from methodologically strong research paradigms has led to little certainty about many aspects of homeschooling including its …

Multiple Species Of Distinctiveness In Memory: Separating Task Distinctiveness From Statistical Distinctiveness, Matthew Robert Gretz

Master's Theses

Distinctiveness refers to the memorial benefit of processing unique or item-specific features of a memory set relative to a non-distinctive control. Traditional distinctiveness effects are accounted for based on qualitative differences in how distinctive items are encoded at the time of study. This thesis project aims to evaluate whether a different species of distinctiveness—statistical distinctiveness—may provide a separate contribution to memory beyond traditional encoding-based processes. Statistical distinctiveness refers to the relative frequency with which a specific memory item or set is processed. The current study evaluated statistical distinctiveness through a series of mixed groups in which DRM lists were studied …

Implicit Bias And The Boundaries Of Belief: A Single-Representational Dual-Attitude Account Of Implicit Attitudes, Austin Dakota Synoground

Graduate Theses and Dissertations

Since their inception, implicit attitudes have been defined as associative mental states, separate from beliefs, which are considered to be propositional in nature. Recently, several philosophers have challenged this distinction, arguing that implicit attitudes are actually unconscious beliefs. In turn, I argue that the attitudes detected by current experimental paradigms are blind to distinctions between implicit attitudes, which I define as the products of an associative learning mechanism, and unconscious beliefs, which are the products of a propositional learning mechanism. Specifically, I argue for a single-representational dual-attitude account of implicit bias.

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian

Graduate Theses and Dissertations

Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …

Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.

Electronic Theses and Dissertations

Cognitive flexibility is a hallmark of individuals with higher working memory capacity (WMC). Yet, research demonstrates that higher WMC individuals are sometimes more likely to adopt rigid problem-solving approaches. The present research examines a novel account for these contradictory findings—that different WMC mechanisms interact in ways that both support and constrain cognitive flexibility. Across three studies, participants completed the water jug task—a problem-solving task requiring them to first establish and then break mental set using a complex strategy. Participants then completed measures targeting three WMC mechanisms: attention control, primary memory, and secondary memory. Study 1 demonstrated that primary memory and …

Disordered Eating, Depression, And Cognitive Vulnerabilities In College Women., Kelsea Visalli

Electronic Theses and Dissertations

This study tests a path model of disordered eating and symptoms of depression derived from the Hopelessness Theory of Depression (Abramson, Metalsky, & Alloy, 1989). The model proposes that cognitive vulnerabilities to depression will be associated with disordered eating behaviors and symptoms of depression in college women. A sample of undergraduate women (n = 181) completed self-report measures assessing disordered eating symptoms and symptoms of depression. Findings revealed that one, but not all, cognitive vulnerability was associated with disordered eating behavior, and that disordered eating behaviors and symptoms of depression are bi-directionally associated. Implications and future research directions are discussed.

Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race

Graduate Theses and Dissertations

Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …
