Psychological Construct Validity, Caroline Marie Stone

Arts & Sciences Graduate Student Theses and Dissertations

A primary concern for any psychological research project is determining how to measure unobservable mental entities, such as "implicit memory", or "intelligence". Psychologists say that a measure has construct validity when they believe that a measurement method measures the construct they intend it to measure, where a construct is any theoretical term that refers to a mental entity. Construct validity, then, is the process of justifying one's belief that a measure has construct validity. My dissertation seeks to answer three related questions, 1. What is construct validity?, 2. What is the best epistemic theory of justification for construct validation?, and …

Oppression And The Limits Of Individual Moral Progress, Cameron Charles Evans

Arts & Sciences Graduate Student Theses and Dissertations

Systemic social problems are the product of complex interactions among institutions, policies, biases, stereotypes, and false beliefs. While we may be pessimistic about our abilities to combat social change, we may remain optimistic about our abilities as individuals to achieve moral growth. However, in societies organized by socially unjust practices, our individual capacities for improvement may be stunted. My primary concern is to identify key obstacles to our moral development. I argue that "self-help" methods for reducing our social biases and prejudices are ineffective. Our biases interact in complex ways with each other, and with the environment, in ways that …

Vegetarian Diets, Maybe Not As Healthy As You Think, Darryl Goh, Debbie Chan, Merson Hoo, Ian Wong

Introduction to Research Methods RSCH 202

Many are approaching vegetarianism as a viable diet option in recent years, presuming that adopting a vegetarian diet would provide health benefits. This paper explores the possibilities of physical and mental effects that vegetarianism may have on humans and its extent by the use of regression analysis. To measure the possible impacts vegetarian diets may hold on both the physiology and physical aspects of humans, we have utilized the measures of life expectancy and prevalence of depression respectively. Cross-sectional data were examined from sources such as the World Health Organization, Our World In Data and the World Bank, with figures …

The Feeling Mind, Maria Doulatova

Arts & Sciences Graduate Student Theses and Dissertations

According to standard conceptions of agency, our reasons and intentions guide our actions. That is, goal-directed intentions play a key role in practical deliberation, planning, and execution of action. Furthermore, purposeful, goal-directed behavior warrants attributions of responsibility or “reactive attitudes” like resentment, anger, gratitude and forgiveness. However, recent developments of the dual-process theory of mind cast doubt on the empirical adequacy of this picture. While people take themselves to be responding to relevant reasons, they are often bypassed by irrelevant affective or automatic reactions. In this work I go beyond the dual-process theory of mind to offer a mechanistic account …

Event Perception, Emily Prychitko

Arts & Sciences Graduate Student Theses and Dissertations

We seem to perceive events, like songs playing, thunderstorms, and people having conversations. Extensive empirical research suggests that we indeed perceive events. Yet the philosophy of perception has not addressed event perception much at all. I lay out goals and methods for a fruitful philosophical investigation of event perception, then pursue that investigation. Primarily on the basis of the empirical evidence, I argue that we perceive events across the senses, and that event representations are a unique type of perceptual representation. In doing so, I address concerns about event perception as such, relative to object and property perception. I argue, …

Factors Affecting Pubertal Timing And Perceptions Of Birth Control, Ashley L. Gomm

Honors Program Theses and Projects

Menarche is the occurrence of a first menstrual period in the female adolescent. The age of menarche has been decreasing over the past 150 years. While some factors have been identified, like increased body mass index (BMI), such factors alone cannot account for the overall decrease in age.

Due to the decreased age of menarche and as additional uses for oral contraceptive pills (OCPs) have been identified, it is becoming clear that females no longer use “birth control” or “oral contraceptives” primarily to prevent pregnancy, but instead for a myriad other reasons including “menstrual suppression.” Menstrual suppression is …

Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson

LSU Doctoral Dissertations

Mental imagery is a common component in a range of emotion regulation techniques. However, the effectiveness and neural mechanisms of regulation via mental imagery are underexplored due to a lack of studies targeting mental imagery specifically. This discrepancy results in uncertainty regarding the mechanism of regulation in existing paradigms. Biased competition for attentional resources presents a plausible model by which a mental imagery-based distracter can downregulate response to an emotional stimulus. If visualizing an imagined distracter effectively regulates emotional response, the inclusion of mental imagery components in other techniques represents a potential confound. To address this discrepancy, this dissertation investigates …

Big Five Personality Traits And Political Orientation: An Inquiry Into Political Beliefs, Ian E. Phillips

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Personality research centered on the Big Five personality traits has heavily impacted our understanding in regards to what forces orient a person on a political spectrum. Examining how personality differences interact with political orientation, this research seeks to provide information on what makes someone either more or less likely to be liberal or conservative based on their temperament. In this paper, previous personality research is synthesized into one discussion, centered on what the effects of each trait are and how they impact political orientation, the heritability of personality, and what implications there are for such research in the realm of …

How Covid19 Has Impacted Students Nutrition And Eating Habits With The Abrupt Closure Of Restaurants And Campuses, Chloe Sermet

Student Scholar Symposium Abstracts and Posters

With the ongoing COVID-19 pandemic causing college campuses, restaurants, and businesses to shut down, many college students found themselves having to return home or find alternative food resources. Due to these factors, it was imperative to examine how college student’s eating habits have changed throughout the pandemic, dealing with lots of stressors, and whether having prior education on nutrition influenced those eating habits. To examine those effects, 17 nutrition minors and 126 non-nutrition minors participated in the current study in which they took the College Students Eating Habit survey and the Perception of Peer Pressure Scale. The outcome of the …

Evaluation Of Α-Pyrrolidindovalerophenone (Α-Pvp) And Its Isomers In Male And Female Sprague-Dawley Rats Trained To Discriminate Mdpv, Kaley Cargile

Masters Theses

Recreational use of synthetic cathinones, 3,4-methylenedioxypyrovalerone (MDPV) and α‐pyrrolidinovalerophenone (α‐PVP), has become increasingly popular, thus prompting characterization of their behavioral and neurochemical effects. MDPV has been studied for several years now, though there is still much unknown about α‐PVP, and its isomers. The primary objective of this study was to characterize the discriminative effects of α‐PVP and its isomers in comparison to MDPV. Male and female Sprague-Dawley rats were trained to discriminate 0.5mg/kg MDPV from saline injections under a fixed ratio 20 (FR 20) schedule of food reinforcement. Substitution tests were conducted with MDPV (0.05-0.5mg/kg), α‐PVP (0.05-0.5mg/kg), (S)-α‐PVP (0.05-1mg/kg) and …

Early Communication Abilities Of 24-Month-Old Children With Williams Syndrome As Measured By The Communication Complexity Scale., Sean B. Woods

College of Arts & Sciences Senior Theses

Williams syndrome (WS) is a neurodevelopmental disorder associated with intellectual disability accompanied by a distinct cognitive profile. Despite their socially outgoing nature, children with WS exhibit delayed communication development and specific deficits across various functions of communication. The purpose of this study was to describe the range of communication complexity observed in 24-month-olds with WS and determine relations between communication complexity and other areas of cognitive development. The communication complexity of 17 24-month-old children with WS was measured using the Communication Complexity Scale (CCS), which quantifies optimal and typical communication complexity, as well as optimal communication for Joint Attention (JA) …

The Development And Evaluation Of Novel Da Transport Inhibitors And Their Effects On Effort-Related Motivation: A Review, Mukund Desibhatla

Honors Scholar Theses

Depression is a debilitating disorder that can cause motivational deficits such as psychomotor retardation, anergia, apathy, and fatigue. Recent research indicates that these motivational deficits, and potential pathways of therapeutic intervention, can be studied in animal models involving rats and mice. Treatments with the VMAT-2 inhibitor tetrabenazine (TBZ) and cytokine interleukin-1ß (IL-1ß) can create a low-effort bias and impair effort-related motivation (Nunes et al. 2013, 2014). A number of high-affinity DA transport inhibitors such as d-amphetamine, methylphenidate, and cocaine can restore extracellular DA, albeit with the cost of undesirable effects such as high abuse liability. These observations have led researchers …

Narrative Inquiry: Life Experiences Of Elite Athletes, Sarah Elizabeth Brown

Graduate Theses and Dissertations

Elite athletes face numerous personal and professional pressures and high-stress experiences; however, there is a gap in the literature connecting identity development with these life experiences. Using narrative inquiry analysis with six emerging adult athletes competing at professional and Olympic levels, this study identified self-narratives they created from life experiences within the context of sport and analyzed when these meanings were formed. Athletes described experiences causing great psychological disturbances as a normal risk within their sport and needing to regulate or compartmentalize their emotions to get through those experiences. Participants discussed various roles they play within their team but lacked …

An Eeg Source-Space Analysis Of The Neural Correlates Underlying Self-Regulation, Stephanie M. Long

Graduate Theses and Dissertations

Self-regulation is the cognitive process of controlling our thoughts and behaviors to be aligned with our goals. This process is used in many different contexts and has been associated with contributions from several brain regions. This research aimed to investigate differences in four prefrontal areas of the brain while participants applied four different self-regulation strategies. We recorded EEG while participants (N = 132) performed three tasks which engaged each of the four self-regulation strategies: the AX-CPT task engaged proactive and reactive control, the Go/Nogo task engaged inhibitory control, and the hybrid Flanker Global/Local task engaged the resolution of response conflict. …

Investigation Of Algorithms To Assess Validity Of Wearable Technology During Field Testing, Brenna Barrios

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wearable technology is an emerging fitness trend where the technology which supports it lacks validity verification. Furthermore, heart rate validity of these devices vary greatly when observed in laboratory settings vs. field testing. Secondarily, Consumer Technology Association guidelines require a minimum five minute trial for wearable testing. This study examined heart rate data of previously tested wearable devices (Garmin Fenix 5, Jabra Elite Sport, Motiv Ring, Scosche Rhythm+) in an outdoor setting to further understand their performance, and to examine the relationship of the five minute regulation. Two separate algorithms were applied to the original data set, the first shortened …

Effect Of Nutrition On Resilience In Adults With Childhood Trauma, Carrie Merrill, Nicole Wickstrom, Katie Munn, Timothy Mclaughlin

Thinking Matters Symposium

While previous studies have shown that healthy nutrition has a positive effect on our physical and emotional well-being (Marsman et al., 2018; Harbottle, 2019), it is unknown whether those benefits extend to individual levels of resilience among those who have suffered childhood trauma. The purpose of this research is to better understand how nutritional habits influence the relationship between childhood trauma and resilience. A Qualtrics survey design was used to collect data related to Adverse Childhood Experiences (ACEs), resilience, and nutritional intake, and was sent via email to University of Southern Maine students and faculty of the school of social …

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 …

The Effects Of Acute Exercise On Retrieval Induced Forgetting, Walter Simpson

Honors Theses

Retrieval Induced Forgetting (RIF) is a type of active forgetting that may play beneficial and detrimental roles in long-term memory. The benefit of the retrieval of certain information is that information will become more readily available following subsequent retrieval; a concept termed the retrieval practice effect (RP). The detrimental effect of RIF may be that, upon the subsequent recall of certain information, related information may be inhibited from recall. The effects and mechanisms of RIF have remained a topic of debate among neuroscientists, psychologists, and other related scholars. The goal of this study was to evaluate the effects of acute …

A Participatory Action Research Study Of Police Interviewing Following Crisis Intervention Team Training, Maria Felix-Ortiz, Catherine Steele, Marisa Deguzman, Georgen Guerrero, Melissa Graham

Verbum Incarnatum: An Academic Journal of Social Justice

Estimates vary, but a third to one half of individuals shot and killed by police have a mental illness or disability, and many who are taken into custody languish in county jails where no treatment for their illness is available. The Crisis Intervention Team (CIT) model is an increasingly important adjunct to U.S. police training because it de-escalates tense situations, diverts people with mental illness away from jail and into treatment, and can reduce the risk of civilian deaths during a police encounter. As such, it is a strategy for reducing the social injustice of incarceration or deaths of people …

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.

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 …

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 …

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 …

Domestic Violence In The World Of Athletics, Abbigayle L. Gesler

ONU Student Research Colloquium

There is an ongoing debate whether athletics is linked to domestic violence in professional athletes or individuals who were athletes for a long period of time. The purpose of this research is to see if being an athlete leads to domestic violence, and if so, to find ways to decrease the numbers. Professional athletes with a history of domestic violence will be researched and this could help determine if there is a link between the two. To get an idea on aggression levels in athletes, the Buss & Perry Survey was sent out via email to all Ohio Northern students, …

Kelly, Anjel Fierst, Nathira Ahmad, Caroline Anton, Layla Shaffer, Kairavi Kapila, Logan Driever, Kayla Weaver, Caroline Dial, Maya Crawford, Iso Hartman, Tommy Infantino, Fiona Butler, Abigail Straus, Shakeera L. Walker, Brianna Balugas, Matthew Pardillo, Briana Goncalves, Julian Keenan

Department of Biology Faculty Scholarship and Creative Works

Only by understanding the ability to take a third-person perspective can we begin to elucidate the neural processes responsible for one’s inimitable conscious experience. The current study examined differences in hemispheric laterality during a first-person perspective (1PP) and third-person perspective (3PP) taking task, using transcranial magnetic stimulation (TMS). Participants were asked to take either the 1PP or 3PP when identifying the number of spheres in a virtual scene. During this task, single-pulse TMS was delivered to the motor cortex of both the left and right hemispheres of 10 healthy volunteers. Measures of TMS-induced motor-evoked potentials (MEPs) of the contralateral abductor …

Efficacy Of A Yfv-Specific Monoclonal Antibody In The Treatment Of Yf In A Hamster Model, Ryne Christiansen

Student Research Symposium

The yellow fever virus (YFV) is a flavivirus found mainly in South America and Africa. Infection may result in fever, chills, jaundice, nausea, and vomiting. Outbreaks may have up to 50% case mortality. Although Yellow Fever (YF) is a highly preventable disease through the use of an effective vaccine, there are no approved antivirals for this disease. An effective antiviral is necessary to treat infected individuals in areas where the YF vaccine was not used and an outbreak of YF occurs. In this study, female Syrian golden hamsters were infected with YFV and treated with YFV-specific monoclonal antibodies (mAbs). Weight …

Patch Clamps, Electrophysiology, And The Optimistic Future Of Neuroscience At Usu, Riley Conover-Elmer

Student Research Symposium

The Neuroscience department is a small, yet nonetheless rapidly growing field at Utah State University. While many students are encouraged to take classes from related fields such as psychology and biology, an official Bachelor's degree has not yet been published for the university. As one of those students, digging deeper into the world of neuroscience has yielded many discoveries on biology/behavior relations that go largely unnoticed by the general student population. However, in preparation for a coming Neuroscience Major, I was given the opportunity to assist Dr. Sara Freeman in preparing for a Neurophysiology Lab course in the Spring of …

Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman

Honors Thesis

Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …
