The Journey Back To Wholeness That Already Is, Jenna Dishy Wes Mar 2021

The Journey Back To Wholeness That Already Is, Jenna Dishy Wes

Journal of Conscious Evolution

If we are born into this world with in an already heightened state of consciousness, at what point in human development do we begin to disconnect? Is the human experience innately traumatic? Through the exploration of Piaget’s stages of development, and in coherence with the concept of transgenerational trauma, I explore moments and modes of intervention, with the intention of building on what is already whole instead of waiting until it is broken. Rather than spending another generation spending our lives trying to heal, reaching for enlightenment and soul connection, what if our end point was actually our beginning one?


Decomorose: The Somatic Flowering Of The Living Quality, Shaun J. Martin Mar 2021

Decomorose: The Somatic Flowering Of The Living Quality, Shaun J. Martin

Journal of Conscious Evolution

This essay is an exploration of the human maturation process from a transpersonal point of view. The main premise of the essay is the notion that our maturation on the level of consciousness (the living quality) is not synonymous with our bodily maturation or the ongoing construction of our social personality (the identity project). It suggests that transpersonality is a fundamental component in human development, but has been overlooked and left out in most areas of modern culture. The recent rise of mental illnesses and the overall frustration or discontent within our society is a direct result of infrastructures that …


Neurocognitive Interactions Between Anticipatory Anxiety And Memory Encoding, Felicia M. Chaisson Mar 2021

Neurocognitive Interactions Between Anticipatory Anxiety And Memory Encoding, Felicia M. Chaisson

LSU Master's Theses

Although acute anxiety has been shown to improve encoding of threat-relevant information, its effects on threat-neutral information are less understood. Recent research suggests that anxiety can impair subsequent recall for neutral words, particularly following practice with the recall task. Here we use event-related potentials (ERPs) to test the notion that anxiety specifically disrupts the implementation of encoding strategies—such as elaborative encoding—that tend to develop with practice. ERPs were recorded as participants studied two sets of neutral words, one of which was presented in a stressful context using the threat-of-shock paradigm (threat block), and the other in a non-threatening context (safe …

Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore Mar 2021

Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore

Publications and Research

Rehearsal during working memory (WM) maintenance is assumed to facilitate retrieval. Less is known about how rehearsal modulates WM delay activity. In the present study, 44 participants completed a Sternberg Task with either intact novel scenes or phase-scrambled scenes, which had similar color and spatial frequency but lacked semantic content. During the rehearsal condition participants generated a descriptive label during encoding and covertly rehearsed during the delay period. During the suppression condition participants did not generate a label during encoding and suppressed (repeated “the”) during the delay period. This was easy in the former (novel scenes) but more difficult in …


How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel Mar 2021

How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel

Department of Psychology Faculty Scholarship and Creative Works

Drawing upon multidimensional theories of intelligence, the current paper evaluates if the Geneva Emotional Competence Test (GECo) fits within a higher-order intelligence space and if emotional intelligence (EI) branches predict distinct criteria related to adjustment and motivation. Using a combination of classical and S-1 bifactor models, we find that (a) a first-order oblique and bifactor model provide excellent and comparably fitting representation of an EI structure with self-regulatory skills operating independent of general ability, (b) residualized EI abilities uniquely predict criteria over general cognitive ability as referenced by fluid intelligence, and (c) emotion recognition and regulation incrementally predict grade point …


Supply Chain Student Biases Regarding Transportation Jobs, Drew Mahosky Mar 2021

Supply Chain Student Biases Regarding Transportation Jobs, Drew Mahosky

Information Systems Undergraduate Honors Theses

As a Supply Chain student at the University of Arkansas, I have made some observations about how students view jobs with a transportation focus. I have seen other students gravitate towards jobs on the consumer-side of the supply chain job market, with many joining large companies like Walmart and Amazon. The university itself has helped instill this feeling in me as well, due to their focus more on the consumer-side of supply chains. There have only been two classes offered to me thus far in my degree plan that I felt truly addressed transportation-side supply chains at all, with them …


Automaticity Of Lexical Access In Deaf And Hearing Bilinguals: Cross-Linguistic Evidence From The Color Stroop Task Across Five Languages, Rain G. Bosworth, Sarah C. Tyler, Eli M. Binder, Jill P. Morford Mar 2021

Automaticity Of Lexical Access In Deaf And Hearing Bilinguals: Cross-Linguistic Evidence From The Color Stroop Task Across Five Languages, Rain G. Bosworth, Sarah C. Tyler, Eli M. Binder, Jill P. Morford

Articles

The well-known Stroop interference effect has been instrumental in revealing the highly automated nature of lexical processing as well as providing new insights to the underlying lexical organization of first and second languages within proficient bilinguals. The present cross-linguistic study had two goals: 1) to examine Stroop interference for dynamic signs and printed words in deaf ASL-English bilinguals who report no reliance on speech or audiological aids; 2) to compare Stroop interference effects in several groups of bilinguals whose two languages range from very distinct to very similar in their shared orthographic patterns: ASL-English bilinguals (very distinct), Chinese-English bilinguals (low …


Conflict Resolution In The Virtual World: The Impact Of Covid-19 On New Ways Of Doing Business, Eileen P. Petzold-Bradley Feb 2021

Conflict Resolution In The Virtual World: The Impact Of Covid-19 On New Ways Of Doing Business, Eileen P. Petzold-Bradley

Peace and Conflict Studies Journal Conference

Overview

The world-wide-web development in the 1990s has led to the Online Dispute Resolution (ODR) movement over the last two decades. As digital and internet technology has become globally widespread, discovering new ways of using online tools for dispute resolution is becoming more prevalent. Living in a digital culture, “also known as digitality or digitalism,” has become a norm for our post-modern society. As we continue to witness in the conflict resolution field, incorporating technology into the dispute resolution processes is becoming more commonplace for practitioners.

As ODR continues to be seen ripe for innovation and as a valuable tool …


Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis Feb 2021

Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Across species, unpredictable patterns of maternal behavior are emerging as novel predictors of aberrant cognitive and emotional outcomes later in life. In animal models, exposure to unpredictable patterns of maternal behavior alters brain circuit maturation and cognitive and emotional outcomes. However, whether exposure to such signals in humans alters the development of brain pathways is unknown. In mother–child dyads, we tested the hypothesis that exposure to more unpredictable maternal signals in infancy is associated with aberrant maturation of corticolimbic pathways. We focused on the uncinate fasciculus, the primary fiber bundle connecting the amygdala to the orbitofrontal cortex and a key …


The Rac-Gef Tiam1 Promotes Dendrite And Synapse Stabilization Of Dentate Granule Cells And Restricts Hippocampal-Dependent Memory Functions, Jinxuan Cheng, Federico Scala, Francisco A Blanco, Sanyong Niu, Karen Firozi, Laura Keehan, Shalaka Mulherkar, Emmanouil Froudarakis, Lingyong Li, Joseph G Duman, Xiaolong Jiang, Kimberley F Tolias Feb 2021

The dentate gyrus (DG) controls information flow into the hippocampus and is critical for learning, memory, pattern separation, and spatial coding, while DG dysfunction is associated with neuropsychiatric disorders. Despite its importance, the molecular mechanisms regulating DG neural circuit assembly and function remain unclear. Here, we identify the Rac-GEF Tiam1 as an important regulator of DG development and associated memory processes. In the hippocampus, Tiam1 is predominantly expressed in the DG throughout life. Global deletion of Tiam1 in male mice results in DG granule cells with simplified dendritic arbors, reduced dendritic spine density, and diminished excitatory synaptic transmission. Notably, DG …

Methodology: The phenomenological qualitative study involved exploring the lived experiences of 12 Black women in positions of leadership in northern California state government with regard to the supports they received and the barriers they encountered during their careers in California state government. Patton (2015) asserted that phenomenology's philosophical interpretation occurs when individuals only know what they experience. Additionally, "to fully understand the phenomenon, it must be …


Cd38 Is Associated With Bonding-Relevant Cognitions And Relationship Satisfaction Over The First 3 Years Of Marriage, Anastasia Makhanova, James K. Mcnulty, Lisa A. Eckel, Larissa Nikonova, Jennifer A. Bartz, Elizabeth A.D. Hammock Feb 2021

Cd38 Is Associated With Bonding-Relevant Cognitions And Relationship Satisfaction Over The First 3 Years Of Marriage, Anastasia Makhanova, James K. Mcnulty, Lisa A. Eckel, Larissa Nikonova, Jennifer A. Bartz, Elizabeth A.D. Hammock

Psychological Science Faculty Publications and Presentations

Although there are numerous benefits to having a satisfying romantic relationship, maintaining high levels of relationship satisfaction is difficult. Many couples experience declines in relationship satisfaction in the early years of marriage, and such declines predict not only relationship dissolution but also poor mental and physical health. Several recent studies indicate that genetic variation on the CD38 gene (CD38), at the single nucleotide polymorphism (SNP) rs3796863, is associated with cognitions and behaviors related to pair bonding; we thus leveraged longitudinal data from a sample of newlywed couples (N = 139 genotyped individuals; 71 couples) to examine whether …


The Role Of Perceived Warmth And Competence In Civil Trials With Corporate Litigants, Alexander C. Jay Feb 2021

The Role Of Perceived Warmth And Competence In Civil Trials With Corporate Litigants, Alexander C. Jay

Dissertations, Theses, and Capstone Projects

Corporations are involved in approximately 40% of all civil litigation (Langton & Cohen, 2008), yet there is much to be learned concerning how jurors make decisions in trials involving corporate litigants. Mock juror research suggests that for-profit corporations are treated more harshly than other defendants, such as non-profit corporations and individuals (e.g., Hans, 1998). This discrepant treatment of for-profit corporate defendants might be linked to unmitigated stereotypical perceptions of them being low in warmth (i.e., likely to have immoral intentions) but high in competence (i.e., likely to be capable of acting on those intentions; Aaker et al., 2010). Research shows …


An Evaluation Of An Application Designed For The Ipad® To Measure Stimulus Overselectivity For Future Use In Autism Research, Adrienne A. Fitzer Feb 2021

An Evaluation Of An Application Designed For The Ipad® To Measure Stimulus Overselectivity For Future Use In Autism Research, Adrienne A. Fitzer

Dissertations, Theses, and Capstone Projects

Twenty-three college students participated in two studies evaluating an application designed to measure stimulus overselectivity in pictures depicting facial affect. We analyzed whether this application worked as designed by evaluating whether it could provide a robust analysis of the types of errors users make (e.g., by matching by the top features, the bottom features, or not by the top or the bottom features), and the extent to which the application worked to decrease selective responding in the event a user was not matching consistently by all features. We also evaluated if participant scores on the Autism Quotient and RAADS-14 could …

Methods: Respondents included (n = 255) residents from the Midwest and Southern regions of U.S. Participants completed an online survey between 28 October and 3 December 2014 during the height of Ebola-related media coverage.

Results: Findings reveal that increased exposure to EVD media content was associated with increased threat severity and personal susceptibility. …


Effects Of Mindfulness Meditation On Selective, Sustained Attention, Brain Neural Oscillations, And Short-Term Memory, Anamaria Guzman Feb 2021

Effects Of Mindfulness Meditation On Selective, Sustained Attention, Brain Neural Oscillations, And Short-Term Memory, Anamaria Guzman

Honors Program: Senior Projects (Public)

The following extended literature review and research proposal study started initially as a complete research proposal but, due to the challenges COVID-19 has brought, it has become a stand-alone piece of work without data collection. The goal is to synthesize a broad range of literature and previous research on mindfulness meditation and its effects on attention, memory, and brain activity and thus, offering a new perspective and a proposed research path on this subject. This proposed research study, besides previous studies, indicates that mindfulness meditation is expected to improve and enhance selective and sustained attention, which results in better attentional …


Motivation And The Primacy Of Perception : Merleau-Ponty's Phenomenology Of Knowledge, Peter Antich Feb 2021

Motivation And The Primacy Of Perception : Merleau-Ponty's Phenomenology Of Knowledge, Peter Antich

Ohio University Press Open Access Books

Merleau-Ponty’s phenomenological notion of motivation advances a compelling alternative to the empiricist and rationalist assumptions that underpin modern epistemology.

Arguing that knowledge is ultimately founded in perceptual experience, Peter Antich interprets and defends Merleau-Ponty’s thinking on motivation as the key to establishing a new form of epistemic grounding. Upending the classical dichotomy between reason and natural causality, justification and explanation, Antich shows how this epistemic ground enables Merleau-Ponty to offer a radically new account of knowledge and its relation to perception. In so doing, Antich demonstrates how and why Merleau-Ponty remains a vital resource for today’s epistemologists.


Fundamental Principles Of Metacognition: A Qualitative Study Of Metacognition, Pedagogy And Transformation, Philip Hulbig Jan 2021

Fundamental Principles Of Metacognition: A Qualitative Study Of Metacognition, Pedagogy And Transformation, Philip Hulbig

Educational Studies Dissertations

This study investigated the transformative quality of a metacognitive education. It examined a transformative metacognitive education from both the subjective personal perspective of the student who has gone through the process of transformation and the more objective pedagogical perspective of the professors who work to bring forth such transformational experiences in their students. Through interview and analysis these perspectives were integrated to produce a pedagogical theoretical framework derived from experience and grounded in observations about metacognition across various scientific disciplines. The personal elements of metacognition that promote educational transformation from within the students were contrasted with the pedagogical approaches of …


The Effect Of The Difference In The Perception Of Temperature Between Sexes On The Academic Performance Of Chapin High School Students, Tiffany V. Phan Jan 2021

The Effect Of The Difference In The Perception Of Temperature Between Sexes On The Academic Performance Of Chapin High School Students, Tiffany V. Phan

Journal of the South Carolina Academy of Science

Mental performance and mental functions may be negatively affected by decreases in thermal comfort as a result of large differences in temperature. Additionally, females are seen to be less content with room temperatures and actually prefer rooms with higher temperatures in comparison to males. This investigation explored the potential effect that sex plays in thermal perception and the impact it may yield on academic performance within a high school population. It was hypothesized that female students would experience an increase in academic performance as the temperature increased while males would experience the opposite effect. A quasi-experimental approach was used to …

Central Nervous System Intravascular Lymphoma Leading To Rapidly Progressive Dementia, Christie G Turin, Kevin Ting, Anthony Bradshaw, S Richard Dunham, Karen Nunez-Wallace, Shital M Patel, Priti Dangayach, Stephanie Holdener, Weei-Chin Lin

Faculty, Staff and Students Publications

Intravascular lymphoma is an uncommon subtype of B-cell lymphoma with neoplastic cells limited to the lumen of small blood vessels. We report a case of a 52-year-old man who presented with constitutional symptoms and rapidly progressive dementia. He was found to have diffuse leptomeningeal and faint parenchymal enhancement on magnetic resonance imaging and was subsequently diagnosed with intravascular lymphoma following a brain biopsy. He responded remarkably well to systemic and intrathecal chemotherapy. The diagnosis and treatment of intravascular lymphoma have been guided by a few case reports and are largely based on expert opinion.


Database Of Picture-Based Cognitive Reappraisal Experiments: Analyses Of Trial-Level Factors, Damon Abraham Jan 2021

Database Of Picture-Based Cognitive Reappraisal Experiments: Analyses Of Trial-Level Factors, Damon Abraham

Electronic Theses and Dissertations

Cognitive reappraisal is widely recognized as an effective emotion regulation strategy for managing negative emotions. In laboratory research, reappraisal has been shown to attenuate self-reported negative affect as well as physiological and neurological markers of emotion and arousal. In these experiments, emotionally evocative images are frequently used to induce negative affect in participants. Depending on the trial condition, participants are instructed to either look and react naturally or to change their experience using reappraisal. Data are typically aggregated within trial condition, and the average difference in reported negative affect between conditions serves as the behavioral measure of reappraisal success. While …

Understanding Stability In Cognitive Neuroscience Through Hacking's Lens, Jacqueline A. Sullivan Jan 2021

Understanding Stability In Cognitive Neuroscience Through Hacking's Lens, Jacqueline A. Sullivan

Philosophy Publications

Ian Hacking instigated a revolution in 20th century philosophy of science by putting experiments (“interventions”) at the top of a philosophical agenda that historically had focused nearly exclusively on representations (“theories”). In this paper, I focus on a set of conceptual tools Hacking (1992) put forward to understand how laboratory sciences become stable and to explain what such stability meant for the prospects of unity of science and kind discovery in experimental science. I first use Hacking’s tools to understand sources of instability and disunity in rodent behavioral neuroscience. I then use them to understand recent grass-roots collaborative initiatives aimed …


Effects Of Human-Animal Interactions On Affect And Cognition, Elise L. Thayer, Jeffrey R. Stevens Jan 2021

Effects Of Human-Animal Interactions On Affect And Cognition, Elise L. Thayer, Jeffrey R. Stevens

Jeffrey Stevens Publications

Human-animal interaction has clear positive effects on people’s affect and stress. But less is known about how animal interactions influence cognition. We draw parallels between animal interactions and exposure to natural environments, a research area that shows clear improvements in cognitive performance. The aim of this study is to investigate whether interacting with animals similarly enhances cognitive performance, specifically executive functioning. To test this, we conducted two experiments in which we had participants self-report their affect and complete a series of cognitive tasks (long-term memory, attentional control, and working memory) before and after either a brief interaction with a dog …


Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad Jan 2021

Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad

Jeffrey Stevens Publications

Teaching owners how to train their dogs is an important part of maintaining the health and safety of dogs and people. Yet we do not know what behavioral characteristics of dogs and their owners are relevant to dog training or if owner cognitive abilities play a role in training success. The aim of this study is to determine which characteristics of both dogs and owners predict success in completing the American Kennel Club Canine Good Citizen training program. Before the first session of a dog training course, owners completed surveys evaluating the behavior and cognition of their dog and themselves. …


Attribute-Based Choice, Francine W. Goh, Jeffrey R. Stevens Jan 2021

Attribute-Based Choice, Francine W. Goh, Jeffrey R. Stevens

Jeffrey Stevens Publications

Alternative-based approaches to decision making generate overall values for each option in a choice set by processing information within options before comparing options to arrive at a decision. By contrast, attribute-based approaches compare attributes (such as monetary cost and time delay to receipt of a reward) across options and use these attribute comparisons to make a decision. Because they compare attributes, they may not use all available information to make a choice, which categorizes many of them as heuristics. Choice data have suggested that attribute-based models can better predict choice compared to alternative-based models in some situations (e.g., when there …


Are Capuchin Monkeys (Sapajus Spp.) Sensitive To Lost Opportunities? The Role Of Opportunity Costs In Intertemporal Choice, Elsa Addessi, Valeria Tierno, Valentina Focaroli, Federica Rossi, Serena Gastaldi, Francesca De Petrillo, Fabio Paglieri, Jeffrey R. Stevens Jan 2021

Are Capuchin Monkeys (Sapajus Spp.) Sensitive To Lost Opportunities? The Role Of Opportunity Costs In Intertemporal Choice, Elsa Addessi, Valeria Tierno, Valentina Focaroli, Federica Rossi, Serena Gastaldi, Francesca De Petrillo, Fabio Paglieri, Jeffrey R. Stevens

Jeffrey Stevens Publications

Principles of economics predict that the costs associated with obtaining rewards can influence choice. When individuals face choices between a smaller, immediate option and a larger, later option, they often experience opportunity costs associated with waiting for delayed rewards because they must forego the opportunity to make other choices. We evaluated how reducing opportunity costs affects delay tolerance in capuchin monkeys. After choosing the larger option, in the High cost condition, subjects had to wait for the delay to expire, whereas in the Low cost different and Low cost same conditions, they could perform a new choice during the delay. …


The Role Of Talker In Adjusting For Different Speaking Rates In Speech Perception, Chloe M Sharpe, Christian Stilp Jan 2021

The Role Of Talker In Adjusting For Different Speaking Rates In Speech Perception, Chloe M Sharpe, Christian Stilp

Undergraduate Arts and Research Showcase

Speech perception is heavily influenced by acoustic context effects, where perception of a sound is influenced by acoustic properties of surrounding sounds. Talker variability, or the acoustic variability among different talkers, can disrupt these context effects. Studies have shown that talker variability does impact Spectral Contrast Effects (SCEs; an acoustic context effect induced by variations in frequency), but it is unknown if Temporal Contrast Effects (TCEs; an acoustic context effect induced by speech rate) are similarly affected. To test this, on each trial, listeners heard a context sentence (spoken at a fast or slow rate) followed by the target word …
