Impact Of A Dialogic Reading Intervention On The Effectiveness Of Adaptive Magnitude Comparison Ebooks For Improving Young Children’S Magnitude Comparison Skills, Patrick C. Ehrman

Honors Theses

Dialogic reading interventions have been used successfully to increase literacy and language skills, including math language. This study aims to investigate whether a dialogic reading intervention will assist children with spatial and numerical magnitude comparison skills learned through a novel adaptive eBook designed to be read together by parents and children. We propose that a dialogic reading intervention used with an adaptive magnitude comparison eBook will improve children’s spatial and numerical magnitude comparison skills and general math skills compared to control groups. Preschool-aged children and their parents (N=27) were randomly assigned to one of three conditions: adaptive magnitude comparison eBooks …

The Effects Of Cannabinoids On Stress-Coping Behaviors And Neuroendocrinological Measures In Chronic Unpredictable Stress: A Preclinical Systematic Review And Meta-Analysis, Noa Reuveni

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is unclear if cannabis helps individuals cope with life’s stressors or increases the likelihood of developing stress-related disorders such as depression. Chronic unpredictable stress is a validated model of depression that exposes rodents to a series of frequently-occurring, intermittent stressors over the course of a few weeks. This systematic review and meta-analysis summarizes existing research using rodents on the effects of cannabinoids on stress-coping behaviors and neuroendocrinological measurements in chronic unpredictable stress. Databases were systematically searched for articles that met inclusion criteria, and effect sizes between control chronic unpredictable stress groups and cannabinoid-treated chronic unpredictable stress groups were calculated. …

Coherence, Travis Walthall

Electronic Theses and Dissertations

COHERENCE is a series of oil paintings and pen drawings that explores open narratives, or different ways to read artwork. The paintings and drawings showcase harmony, or tension, between ambiguous and representational forms. The visual experience requires the viewer to create their own narrative and decipher forms to do so. COHERENCE is a psychological and aesthetic exhibition fueled from human experience— one of fragility, uncertainty, imperfection, beauty, faith and memories.

Circulating Endocannabinoids And Prospective Risk For Depression In Trauma-Injury Survivors, Jacklynn M. Fitzgerald, Samantha Chesney, Tara Sander Lee, Karen J. Brasel, Christine L. Larson, Cecilia J. Hillard, Terri A Deroon-Cassini

Psychology Faculty Research and Publications

Biological mechanisms associated with response to trauma may impact risk for depression. One such mechanism is endocannabinoid signaling (eCB), a neuromodulatory system comprised of the CB1 subtype of cannabinoid receptors (CB1R), encoded by the CNR1 gene, and two primary endogenous ligands: 2-arachidonoylglycerol (2-AG) and N-arachidonylethanolamine (AEA), hydrolyzed by monoacylglycerol lipase (gene name MGLL) and fatty acid amide hydrolase (gene name FAAH). Preclinical data suggest that eCB/CB1R signaling acts as a stress buffer and its loss or suppression increases depression-like behaviors. We examined circulating concentrations of the eCBs (2-AG and AEA) days and six months after a traumatic injury …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

Roboethics In Covid-19: A Case Study In Dentistry, Wendy C. Birmingham, Yaser Maddahi, Maryam Kalvandi, Sofya Langman, Nicole Capicotto, Kourosh Zareinia

Faculty Publications

The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures. There have been many efforts in the design and development of robotic systems for applications such as disinfection and eldercare. Healthcare education has seen a lot …

Black-Capped Chickadee (Parus Atricapillus) Food Preference, Isabelle Gilbert

Thinking Matters Symposium

All animals must make decisions on where to find, select, capture, and eat food. These factors contribute to a species’ food preference, such as making decisions on what food to eat based on calories. Optimal foraging theory predicts how an animal behaves when searching for food, including optimization of food type, patch choice, time spent in patches, and movement. All animals also make decisions based on predation risk by avoiding predators and making trade-offs on time spent searching for, pursuing, and handling food. The objective of my study is to examine food preference of black-capped chickadees (Parus atricapillus). Birds may …

“Ichachu”: Ontological Diversity For Assembling Common Futures, Kaliana Conesa

The International Journal of Ecopsychology (IJE)

The present work explores the role of discursive analyses of language as potent elements in networks of discourse and practice. A particular focus is with how language functions in multiple, overlapping registers, and how this affects its ability to motivate and coalesce diverse actors into communities of practice. In particular, usages of sovereignty, food sovereignty, and ontology are explored as a means for understanding the process of cross-cultural eco-social action. Fundamental to these analyses is the precept that registers of language represent an epistemic diversity always operating in collaborations for biocultural sustainability. By “eco-social action,” it is meant any practice, …

Evaluation Of A Vocal Mand Assessment And Vocal Mand Training Procedures: A Systematic Replication, Toni O'Connell

Thesis Projects

Numerous mand training procedures have proven effective in developing mand repertoires in children with developmental disabilities, but selection of treatments is usually arbitrary. Bourret et al. (2004) created and tested a vocal mand assessment to systematically determine an effective mand training procedure, thereby reducing the likelihood of implementing ineffective treatments. However, because a comparison between treatments was not completed, the validity of the assessment requires further investigation. This study sought to replicate and extend the findings of Bourret et al. (2004) by including a comparison between two treatments. Study 1 consisted of a replication of the vocal mand assessment and …

Does Methamphetamine (Ma) Cause Cognitive And Neurological Deficits? An Ecologically Valid Approach, Claire Stover

Psychology Student Scholarship

Major: Psychology
Faculty Mentor: Dr. Victoria Templer, Psychology

Methamphetamine Use Disorder (MUD), which is believed to cause cognitive and neurological deficits, is a growing public health concern in the United States. However, current animal constructs of MUD do not model human use patterns. MA users ramp up to a dosage of ~0.75 mg/kg, but current animal models utilize dosages of 3-15 mg/kg. Observed cognitive and neurological deficits may be caused by neurotoxic dosages of MA, not MA use itself. To test this hypothesis, mice were injected with MA twice/day, five days/week, for six months. Dosage increased over the first month …

Thinking And Talking About Kinds, Ye Ji Seoung

Theses and Dissertations

Three experiments investigated whether definite singular generics (e.g., the dog barks) require that the kind does not contain multiple subkinds. No effect of generic form was found in experiment 1 and 3. However, experiment 2 found people thought there were fewer subkinds when definite singulars referred to the kind.

The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori

Theses and Dissertations

Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …

Representation Of Sex-Linked Properties: Implications For Conceptual Representation And Generics, Olga A. Leus

Theses and Dissertations

Four experiments provide evidence that we represent principled connections between kinds and sex-linked properties such that one type of instance of the kind has a principled connection for the presence of the property and the other type has a principled connection for the absence of that property.

Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo

Theses and Dissertations

Wild lemur primates were tested for social preferences across behaviors. Study found highly conservative social preferences that were very consistent across all behavioral states, despite high fission fusion traits common of lemur groups. This finding lays the foundation for using nearest-neighbor as a proxy of social preference for future endeavors.

Cortisol Relates To Executive Functioning For Children Attending Head Start Preschool, Eleanor D. Brown, Zachary Weaver, Mallory L. Garnett, M. Streich, Geeta Shivde

Psychology Student Work

Background: Approximately 15 million children in the United States grow up in poverty circumstances (National Center for Children in Poverty, 2018), as 24% of all children under the age of 6 live in households with income levels classified as below the federal poverty guideline (Jiang et al., 2016). Recent research has highlighted the impact of early childhood poverty circumstances on physiological systems that respond to stress (Lupien et al., 2001), with implications for typical development in the prefrontal cortex (Hair et al., 2015) and related executive functioning (Blair & Raver, 2016). Method: The present study investigated relations among various components …

The Neurobiological Relationship Between Childhood Maltreatment And Major Depressive Disorder (Mdd), Morgan Clinton

Global Tides

Childhood maltreatment compromises healthy development, impacts neurobiology, and is associated with lasting alterations to emotional perception, processing, and regulation. Most significantly, childhood maltreatment increases the risk for later development of emotional disorders such as major depressive disorder (MDD). The stress associated with both childhood maltreatment and MDD can lead to lasting alterations to the fronto-limbic circuitry. Using functional and structural magnetic resonance imaging, researchers have observed hippocampal atrophy and amygdala hyperresponsiveness in participants who’ve experienced both childhood maltreatment and MDD. Furthermore, researchers have also observed increased connectivity between the hippocampus and amygdala in victims of childhood maltreatment. Because childhood maltreatment …

Innovative Virtual Role Play Simulations For Managing Substance Use Conversations: Pilot Study Results And Relevance During And After Covid-19, Glenn Albright, Nikita Khalid, Kristen Shockley, Kelsey Robinson, Kevin Hughes, Bethany Pace-Danley

Publications and Research

Background: Substance use places a substantial burden on our communities, both economically and socially. In light of COVID-19, it is predicted that as many as 75,000 more people will die from alcohol and other substance use and suicide as a result of isolation, new mental health concerns, and various other stressors related to the pandemic. Public awareness campaigns that aim to destigmatize substance use and help individuals have meaningful conversations with friends, coworkers, or family members to address substance use concerns are a timely and cost-effective means of augmenting existing behavioral health efforts related to substance use. These types of …

Unlearning Myths One Question At A Time, Jessica K. Kolman

Honors College Theses

People may believe in myths such as “you only use 10% of your brain” that are related to psychology. Additionally, belief in these myths may prevail despite education, or in some cases, because of education. Indeed, some research suggests students acquired false memories by remembering the wrong answers instead of the correct information (Nitschke et al., 2019). However, research on how leading questions affects memory can provide insight to this problem. Specifically, research shows that subjects who are presented with leading questions or content are more likely to recall an event consistent with that question (Miller & Loftus, 1976). Such …

Mental Imagery In Fear Extinction: A Multi-Component Examination Based On Behavioral, Physiological, And Neurological Measures, Xinrui Jiang

LSU Doctoral Dissertations

Imagery has long been utilized in clinical treatments of affective symptoms with the assumption that mental imagery can stand in for its perceptual counterpart and exert regulatory effects over emotional responses. While this assumption has its ground in theoretical framework of mental imagery supported by evidence of neurological overlaps between imagery and perception, and clinical applications of imagery interventions were found to be successful, very little has been done through means of experimental examinations.

This investigation began with a differential fear conditioning study (study 1) to simulate and assess imagery extinction. Results provided support for the efficacy of imagery exposure …

Everyday Memory In People With Down Syndrome, Yingying Jennifer Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

A Systematic Review And Meta-Analysis On The Efficacy Of Repeated Transcranial Direct Current Stimulation For Migraine, Guoshuai Cai, Zhu Xia, Leigh Charvet, Feifei Xiao, Abhishek Datta, X Michelle Androulakis

Publications and Research

Purpose: Transcranial direct current stimulation (tDCS) may have therapeutic potential in the management of migraine. However, studies to date have yielded conflicting results. We reviewed studies using repeated tDCS for longer than 4 weeks in migraine treatment, and performed meta-analysis on the efficacy of tDCS in migraine.

Methods: In this meta-analysis, we included the common outcome measurements reported across randomized controlled trials (RCTs). Subgroup analysis was performed at different post-treatment endpoints, and with different stimulation intensities and polarities.

Results: Five RCTs were included in the quantitative meta-analysis with a total of 104 migraine patients. We found a significant reduction of …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai

Theses and Dissertations

Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …

249— The Role Of The Indirect Basal Ganglia Pathway In A Mouse Model Of Repetitive Circling Behavior, Gavin Vaughan, Allison R. Bechard

GREAT Day Posters

Repetitive behaviors are associated with a variety of disorders in humans and are diagnostic for autism spectrum disorders. Repetitive behaviors can be modeled in rodents. In our previous experiments, we have been able to reduce repetitive circling behaviors in mice using a ketogenic diet. The mechanisms behind the ketogenic diet are still under investigation. Previous investigations have indicated that the ketogenic diet plays a role in neurotransmitter functioning. This study sought to investigate the potential role of neurotransmitters in repetitive behaviors by investigating how three drugs (L-741,626, a dopamine receptor antagonist; CGS21680, an adenosine agonist; & CDPPB, a glutamate positive …

258— Differential Response To Cocaine In Mice Exposed To Stress, Gavin Vaughan, Melissa Herman, Isabel Ross, Katie Bugbee, April Rowell, Jennifer Bodzon, Allison R. Bechard Ph.D.

GREAT Day Posters

Exposure to trauma is a risk factor for substance use disorders. Using a mouse model of PTSD, we tested the effects of exposure to a stressor (synthetic fox pheromone: TMT) on response to cocaine. Cocaine induced locomotion and cocaine seeking behavior in a conditioned place preference (CPP) were assessed. TMT was an effective stressor, indicated by freezing behavior, which is a known fear response in mice. In both males and females, TMT-exposed mice showed a greater locomotor response to cocaine compared to control mice, resulting in the interaction between time and TMT treatment. TMT-exposed males, but not females, were overall …

055— Ketogenic Diet And Dendritic Morphology In A Mouse Model Of Repetitive Behavior, Samantha Seeger, Yume Iriyama, Allison R. Bechard

GREAT Day Posters

Repetitive motor behaviors are invariant movements with no apparent function. They are associated with several disorders, including autism spectrum disorders (ASD). However, little is known about the causes of these restricted behavior patterns, and effective treatments are lacking. ASD has recently been treated with a ketogenic diet (KD). Now a popular fad, KD is a high-fat, low-carb diet that has treated intractable epilepsy for decades. However, the mechanisms mediating KD’s beneficial effects are still unclear. We first show KD can attenuate repetitive circling behavior. We then assessed dendritic spine density in the left and right dorsolateral striatum as a potential …

Intellectual Access And Spirituality: The Twin Urgencies Of Responsible American Education, Matthew Schmitz

Educational Studies Honors Papers

America is increasingly, and perhaps overwhelmingly, becoming a society characterized by political divisiveness. At its most extreme form, Hannah Arendt argues such a division can make us vulnerable to a loneliness that destroys our confidence and leaves us dependent on ideologies. A renewed sense of spirituality and intellect are prime candidates for helping us develop a healthy relationship with ourselves that can help counteract this loneliness. Not only that, but fully accessing our intellectual and spiritual sides can give us the confidence to tackle democratic republican citizenship the way Thomas Jefferson envisioned it. Here, Jacques Rancière helps us to construct …
