Do Psychopathic Traits Influence Post-Traumatic Growth? Testing The Moderating Effects Of Psychopathic Traits Between Stressful Life Events And Post-Traumatic Growth, Ariela Denham

Honors Theses

The present study investigated the relationship between psychopathic traits and post-traumatic growth (PTG) following exposure to stressful life events. A sample of 291 undergraduate students completed self-report measures including the Triarchic Psychopathy Measure (TriPM), Post-Traumatic Growth Inventory (PTGI), and the Life Events Checklist for DSM-5 (LEC-5). Pearson correlations and hierarchical regression analyses were conducted to test whether the TriPM dimensions—Boldness, Meanness, and Disinhibition—moderated the association between stressful life events and PTG. Results revealed that Meanness was negatively associated with PTG, while Boldness and Disinhibition were not significantly related. Boldness showed a positive relationship with the PTGI Strength subscale, suggesting a …

The Endocannabinoid System's Influence And Modulation Of Nociception, Doreen M. Flannery

Honors Thesis

The anatomy and physiology of pain is a well-defined pathway where noxious stimuli is processed by different systems in the brain. The central research question of this review is how can we better understand the neurobiological effects pain has, and assess if there is therapeutic potential in using endocannabinoids to modulate these effects. Endocannabinoids are signaling molecules that play a key role at both the cellular and molecular level in modulating both acute and chronic pain by influencing different processes within each level that affect how the body responds to both internal and external stimuli. The endocannabinoid system is a …

Impact Of Visual And Auditory Distractors On Spot-The-Difference Task Performance, Julia N. Gross, Alexia Urban, Julius Kloepfer, Hannah Eversole

Aurora

In everyday life, individuals are faced with tasks that require sustained, visual attention. However, distractions are also a part of everyday life, and with the increase in technology use came an increase in distractions that may affect concentration and performance on these visual tasks. Previous research has examined how task-unrelated visual and auditory stimuli, presented at different intensities, impact functions of learning and memory. However, it has yet to determine their impact on ongoing, attention-demanding, visual tasks. The present study used a 2x2 between-subjects design to test the impact of both visual and auditory distractors, presented at either a high …

An Adaptive Paradox: Improvised Drama Therapy And Dialectical Behavior For Eating Disorders In Teens, Krystany Taylor

Expressive Therapies Theses

The complexity of treating eating disorders compels professionals to investigate collaborative and integrative approaches to address psychological rigidity and emotional aversion in affected individuals. Mindfulness within Dialectical Behavior Therapy (DBT) and improvisational theater techniques may contribute to advancing emotional flexibility. This thesis study explored spontaneity in expressive therapy and gauged budding adaptive skills related to emotion regulation in minors with eating disorders. At a behavioral health center in Southern California, I held a dual role as a group facilitator and trainee drama therapist; I therein joined DBT and improvised drama therapy methods into a group treatment setting for ages 14 …

As If We Could Get Along: Dramatic Reality’S Influence On The Prosociality Of Adolescent Boys With Problematic Sexual Behavior, Joel David Bender

Expressive Therapies Theses

There is a strong need for novel treatment approaches for adolescents with problematic sexual behavior (PSB), considering that historically, treatment approaches for adult sex offenders have been blindly applied to youth. Adolescent boys with PSB are at risk for poor treatment outcomes when they engage in anti-social behaviors and group hostility. Dramatic reality, a core process in drama therapy, may assist in transforming the experience of boys in their capacity to exhibit prosocial behavior, given that dramatic reality inherently augments reality. This community arts workshop used purposive sampling in a day treatment center for adolescent boys with PSB and explored …

Investigating The Effects Of Sod1 Knockout On Oxidative Stress And Stress Coping Styles In Zebrafish Using Crispr Technology, Tai Prauner, Ryan Wong

Theses/Capstones/Creative Projects

Reactive oxygen species are byproducts of cellular metabolism that, when not efficiently neutralized, can damage DNA, proteins, and lipids. Superoxide dismutase 1 (SOD1) is an antioxidant enzyme that converts superoxide radicals into less harmful molecules. While its molecular function is well documented, the role of SOD1 in shaping stress-related behavior remains underexplored. This project aimed to establish foundational tools for studying the behavioral impact of SOD1 knockout across proactive and reactive stress-coping styles in zebrafish.

To support future gene-editing experiments, microinjection and breeding protocols were refined across wildtype AB, proactive, and reactive zebrafish lines. No embryos were injected with CRISPR-Cas9 …

Descriptive Statistical Examination Of Mental Health Challenges Faced By International Students, Niharika Perkari

Electronic Theses, Projects, and Dissertations

The mental health and well-being of international students is an increasingly important concern for universities worldwide. International students often encounter unique challenges, including cultural transitions (Ward, Furnham, & Bochner, 2001; Furnham & Bochner, 1986), academic pressure (Yeh & Inose, 2003), financial constraints and social integration difficulties (Hendrickson, Rosen, & Aune, 2011; Sawir et al., 2008; Lee & Rice, 2007) which significantly impact their mental health. This study employs descriptive statistical methods to analyze the mental health challenges faced by international students aiming to identify trends, stressors, coping mechanisms and risk factors. Some datasets comprising survey responses from international students were …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

A Psychometric Evaluation Of The Intentionality Bias Task, David Willard

Graduate Theses and Dissertations (2019 - present)

Intentionality Bias Task (IBT) provides quick and easy assessment of the tendency to overattribute intentionality to the behaviors of others. The IBT has been used repeatedly in research that has attempted to connect intentionality bias to a wide range of disorders and socio-emotional abilities, including schizophrenia spectrum disorder, autism spectrum disorder, and cognitive empathy. To date, however, there has been no systematic examination of the IBT’s psychometric properties. The present study attempts to fill this gap by testing whether the IBT possesses a reliable factor structure. Specifically, the 34 items of the IBT were written to reflect two types of …

Am I Woke Enough To Serve In Healthcare: A Secondary Analysis Of Pre-Health Students’ Personal And Professional Growth By Engaging In Cultural Competency Assessments, Harolynn Williams

All Dissertations

Healthcare providers must be equipped to serve an increasingly diverse population, yet cultural competence remains underemphasized in undergraduate pre-health education. This study explored how embedded cultural competency training influences undergraduate pre-health students’ perceptions of personal and professional growth. Using a qualitative descriptive design, the research incorporated intercultural assessments, the Intercultural Development Inventory (IDI), and the Global Competence Certificate (GCC), along with qualitative reflections from students enrolled in three versions of a cultural competence course: a year-long course, a semester-long course, and a short-term study abroad immersion six-week course. Findings revealed that students demonstrated measurable growth in cultural awareness, knowledge, communication, …

Theses and Dissertations

In today’s world, where technology is advancing rapidly and security threats are becoming more complex, the need for effective home safety measures is more critical than ever. Homeowners are increasingly turning to a variety of smart devices, such as smoke detectors, carbon monoxide detectors, and security cameras, to protect their living spaces against potential dangers like burglary, fire, and environmental hazards. These devices offer essential protection, acting as both early warning systems and visual surveillance tools. However, their effectiveness largely hinges on how well they are placed within the home. Proper placement of these safety devices ensures that they provide …

Multiple Regression, Christian Delucia, Kaleb Pratt, Ashley R. Strong

Essays in Developmental Psychology

Researchers use statistical models to test hypotheses about developmental phenomena. The multiple regression model is a powerful and flexible statistical model that can be used to answer a multitude of research questions. For example, a researcher might be interested in testing whether parent substance use, peer substance use, and lower school performance are risk factors for adolescent substance use. By collecting data on a sample of adolescents, a researcher could use a multiple regression model to provide insights into this research question. Below, we provide a brief, non-technical introduction to the multiple regression model.

Mirror Test Of Infant Self-Awareness, Jenna Bekkala, Naomi J. Aldrich

Essays in Developmental Psychology

Our understanding of self, or belief in one’s being as distinct from others, has been a subject of inquiry throughout human history. Discussions of self-concept would not appear in the empirical literature, however, until the mid-19th century. After likening an orangutan’s response to teasing as that of a “naughty child”, Charles Darwin began to question orangutans’ selfconcept by observing reactions to their own mirror images. Darwin’s use of the mirror to gauge self-awareness, a method eventually applied to his own infant son (Darwin, 1877), would remain the most frequently used assessment of self-concept for the next century.

Correlational Studies, Alexander Beaujean, Hannah Greeley

Essays in Developmental Psychology

Correlational studies are a type of research design that involves examining the relation among two or more phenomena. The design's distinguishing features are (a) data are collected more or less simultaneously, or at least treated as if they were collected at a single point in time; and (b) there is no manipulation of phenomena (e.g., assigning participants into groups).

Longitudinal Studies, Alexander Beaujean

Essays in Developmental Psychology

Longitudinal studies provide information about phenomena constancy and change. Their core feature is that the phenomena under investigation are observed repeatedly in the same participants (e.g., persons, animals, organizations), which requires collecting data at multiple time points (called waves). The participants, phenomena observed, duration of study, and number of waves can greatly differ between studies. For example, longitudinal studies with animals often gather data across many waves, but the entire study may only last a few days or weeks. By contrast, longitudinal studies with humans typically gather data at just a few waves but may last years or decades.

Sequential Studies, A. Alexander Beaujean

Essays in Developmental Psychology

Sequential studies combine aspects of longitudinal and cross-sectional studies in order to overcome some of inherent problems in both designs. Longitudinal studies can provide rich information about phenomena change, but have two major disadvantages: (a) they can require substantial resources, and (b) they can confound effects of age, cohort (i.e., influences due to shared historical experiences), and time-of-data-collection effects (i.e., events that co-occur with the data collection occasions). Cross-sectional studies require fewer resources, but only provide limited information about developmental change.

Cross-Sectional Studies, Alexander Beaujean, Allison D. Gutierrez

Essays in Developmental Psychology

Cross-sectional studies are a type of research design used to understand time-related constancy and change in phenomena using data collected more or less simultaneously from different groups (called cohorts) of participants (e.g., people, animals, organizations). The cohorts vary on the basis of age or some other temporal phenomena (e.g., developmental stage, grade in school), so the combined sample is thought to represent the focal phenomena in the population at different times (i.e., a cross section). Differences among the cohorts are used to approximate developmental changes.

The Marshmallow Task, Laurel A. Brabson, Hannah M. Coffey, Mary Margaret Ruckle, Cheryl B. Mcneil

Essays in Developmental Psychology

To study the human systems of self-control during delayed gratification, Dr. Walter Mischel and colleagues developed what became the famous Marshmallow Test, published in Science in 1989. This study became a frontrunner in the field of psychology, laying the foundation for future studies in impulse control. Dr. Mischel was born in 1930 in Vienna, Austria. He was a professor at the University of Colorado, Harvard University, and Stanford University where he originally conducted the Marshmallow Test. Dr. Mischel currently holds a professorship at Columbia University.

Systematic Observation, Brizel Trinidad, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Systematic observation is the process of explicitly defining desired target behaviors and observing them using a systematic set of guidelines. Systematic observation assists in reducing or eliminating bias in experimental designs. The reduction allows for increased reliability and validity therefore, an integral part in experimental designs. This process is widely used in school, home, and clinical settings. The process allows preset rules and guidelines to be to be followed prior to beginning the experiment. The rules and guidelines maintain the design within reasonable boundaries. All the preset rules are inferred prior to starting the experiment.

Provision Of Brand Information And Critical Reasoning Predict Advertising Literacy, Eugene Zheng Yao, Alexandra List

Journal of Media Literacy Education

This study investigated students’ critical reasoning about commercials, as an aspect of advertising literacy. Critical reasoning was examined under two different experimental conditions. That is, students were tasked with watching four different commercials with 1) brand information provided or not, and 2) asked to engage in critical reasoning or not. The commercials chosen used various production techniques (e.g., socially conscious marketing) to mask their persuasive message. Students provided with brand information within commercials had significantly higher critical reasoning scores when viewing two, out of the four, commercials, and significantly higher overall Analysis of Persuasive Intent (API) scores and brand recall. …
