Keeping Track Of Time: Does Formal Education Of Temporal Symbols Refine People's Ability To Perceive Time?, Alyssa Gabrielle Smith

Undergraduate Honors Thesis Collection

While many studies find a relation between symbolic and nonsymbolic numerical abilities (e.g., Chen & Li, 2014), whether this relation is causal has been questioned. For example, does learning symbols refine nonsymbolic abilities (i.e., Refinement Hypothesis)? One study found that as children gained proficiency in their verbal counting abilities, their nonsymbolic numerical acuity increased (Shusterman et al., 2016), thus supporting the Refinement Hypothesis. As studies have found similar processing for numerical and temporal abilities (e.g., Walsh, 2003) and a similar relation between symbolic and nonsymbolic timing abilities has been found (e.g., Hamamouche & Cordes, 2020), it begs the question of …

Assessing Trauma Competence Among Title Ix Practitioners: Analyzing Self-Perceived Capability And Associated Factors, Aliena Hansen

Honors Program: Senior Projects (Public)

Sexual assault remains a persistent issue on college and university campuses, and the way institutions respond to survivors can significantly influence their well-being and willingness to seek support. Title IX Practitioners are often responsible for responding to reports of sexual misconduct, making trauma-informed approaches essential in their work. However, relatively little research has examined how practitioners perceive their own trauma-related capabilities. The present study examined self-perceived trauma competence among Title IX Practitioners and explored factors associated with differences in perceived competence. Participants completed a survey assessing their confidence in applying trauma-informed principles when working with complainants. Results indicated variability in …

Perfectionism And Cognitive Flexibility: Comparing The Impacts Of Perfectionism Vs Excellencism On Cognitive Flexibility, Lillian R. Blackburn

Honors College Theses

Perfectionism is often defined as “high standards of performance which are accompanied by tendencies for overly critical evaluations of one’s own behavior” (Frost et al., 1990, p. 450). Although striving for high standards is characteristic of perfectionism, it is also a central concept of the construct of excellencism, that is striving for standards that are both high and attainable. Research has made a distinction between the pursuit of perfection and pursuit of excellence, suggesting perfectionists strive for high unattainable standards, whereas excellencists strive for high yet reasonable standards with more areas of flexibility (Gaudreau et al., 2022).  These differences have …

Bridging The Gap: Educating Students On The Neurodiverse Experience, Riley Axtell

Human Development and Family Sciences Undergraduate Honors Theses

Neurodivergent students face misunderstanding, stigma, and systemic barriers that impact academic and emotional well-being. The purpose of this study was to develop and implement a curriculum-based project designed to educate college students about neurodiverse experiences and improve knowledge, empathy, and understanding. The curriculum was administered in two formats: an in-person format with pre- and post-survey measurements and an online “choose your own adventure” implementation utilizing post-survey measurements. Participants engaged in simulated cognitive and sensory activities that represented experiences associated with dyslexia, ADHD, dysgraphia, and dyscalculia. Although limited by a small sample size, reliance on self-report measures, lack of a pre-survey …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

A Phenomenological Study: The Cultural Identity Of Black Transfer Students In Higher Education, Briana Lashon Levi

Electronic Theses and Dissertations

This qualitative phenomenological study explored the lived experiences of Black transfer students from the California Community College system to Southern Historically Black Colleges and Universities (HBCUs). Guided by two theoretical frameworks, Afrocentric Pedagogy and Black Identity Development Theory (BIDT), the study investigated how participants described and interpreted their cultural identity as they transitioned from a community college to a Southern HBCU. In this study, cultural identity was understood as a holistic construct that included students’ sense of belonging and their experiences of cultural affirmation, which functioned as core components rather than separate constructs from cultural identity. This research specifically focused …

Prefrontal Engagement In Cognitive Flexibility Across Paradigms, Katarina Kalajzic

Honors Scholar Theses

Cognitive flexibility is an executive function that involves dynamically adapting behavior in the face of changing environmental circumstances to achieve a particular goal. Disrupted in numerous psychiatric disorders such as Alzheimer’s disease, schizophrenia, OCD, and depression, the neural correlates of cognitive flexibility are not well understood. However, the prefrontal cortex (PFC) is strongly implicated in executive function and attentional control processes. Thus, we sought to examine the neural circuitry involved in distinct cognitive flexibility tasks – the attentional set-shifting task and the probabilistic 2-armed bandit task. Through optogenetic suppression, we targeted pyramidal neurons of the rodent medial prefrontal cortex, an …

Ai In Wonderland, Bodj Oliver Alngohuro

Honors Scholar Theses

Studies in sound symbolism have revealed a baseline preference for people to associate certain sounds with certain concepts. The Bouba/Kiki effect, for instance, reveals a preference for individuals to associate “Bouba” with a round shape and “Kiki” with a sharp shape (Köhler 1929). Other studies have revealed other associations with certain sounds and names with concepts, such as “Mil” referring to something small and “Mal” referring to something big (Sidhu and Pexman, 2017). This study looks at LLMs and how they compare to humans concerning intuitions for certain names based on sound symbolism.

When Mac Shouldn’T Smile Back: Anthropomorphic Logo And Effect On Consumer Perceptions Of Generative Artificial Intelligence, Ainsley E. Ballard

Honors Scholar Theses

Drawing on prior research suggesting that anthropomorphic design can increase trust, liking, and perceived competence, this research investigates whether these effects extend to generative artificial intelligence logos. A three-group between-subjects study was conducted to examine how varying levels of logo anthropomorphization influenced consumer perceptions of an artificial intelligence brand. In being assigned to one of three logo conditions, humanoid (high anthropomorphism), animalistic (moderate anthropomorphism), or nature/geometric (low anthropomorphism), participants evaluated the new logo across multiple dimensions, including liking, brand fit, trustworthiness, and willingness to buy. Contrary to the initial hypothesis, the low anthropomorphism condition consistently received the most positive ratings, …

Factors Affecting Pedestrian-Vehicle Conflicts: An Empirical Analysis, Christo D. Jamo

Honors Scholar Theses

The number of pedestrian deaths increased by 78% between 2009 and 2023, while other motor vehicle crash deaths increased by 13% in the same period [1]. To identify potential pedestrian safety measures, this study analyzed the effects of location-based demographics, pedestrian phasing type, and other physical infrastructure and behavior variables on the probability of pedestrian-vehicle conflicts at signalized intersections, which is a surrogate measure of crash risk. Data were collected from 55 intersections in Connecticut, and the pedestrian-vehicle interactions were classified by severity based on the Swedish Traffic Conflict Technique: undisturbed passage, potential conflict, minor conflict, or serious conflict. Because …

The Impact Of Traditional Machismo On Mental Health Outcomes: Depression And Suicide Risk Among Latino Immigrant And Non-Immigrant Men, Yesenia A, Romero

Electronic Theses and Dissertations

Traditional masculine norms have long been recognized as influential factors in men’s psychological well-being. Within Latino cultures, the construct of machismo represents a culturally specific form of masculinity characterized by ideals of masculinity and characterized by ideals of strength, dominance, and emotional restraint. While these norms may promote resilience and family responsibilities, rigid adherence to traditional machismo has also been associated with emotional suppression, reduced help-seeking behaviors, and increased psychological distress. The present study conducted a meta-analysis to examine the relationship between traditional machismo and mental health outcomes among Latino men, with particular attention to depressive symptoms as well as …

Christian-Based Community Engagement And Loneliness Among College Students, Ayodeji Fayemi

Loneliness also influences cognitive and social processes and has been linked to physical health risks, highlighting the need for effective interventions. This study examined whether Christian-based community engagement served as a protective factor against loneliness among college students. Grounded in Social Support Theory, the study assessed associations among loneliness, general social support, church-based support, religious coping, institutional integration, …

Task-Dependent Modulation Of The N170 Erp Component In Facial Perception, Mary M. Krdikashyan

Electronic Theses, Projects, and Dissertations

The N170 component plays a key role in face perception, but how attention influences it remains debated. In a series of five electroencephalography (EEG) experiments, we examined how attention to different facial features (holistic versus feature-based) affects the N170 amplitude. This study aims to determine whether perceptual competition explains these effects. In a preliminary study (Experiment 1), participants were primed to focus on either gender, age, emotional expression, race, or no specific task. This study showed a larger amplitude for gender and age, followed by emotion, with minimal differences for race, and no task was assigned. Since all these conditions …

The Relationship Between Telecommuting, Autonomy, And Burnout, Aniko Nagy

Electronic Theses, Projects, and Dissertations

With flexible work arrangements becoming more common, the need to expand our understanding of the relationships between flexible work arrangements and employee health and wellbeing outcomes, such as employee burnout, continues to grow. The purpose of the present study is to explore the relationships between flexible work arrangements, autonomy, and employee burnout. The Job Demands-Resource (Bakker and Demerouti, 2007) and Conservation of Resources (Hobfall & Freedy, 2017) theories propose that job resources such as flextime, flexplace, and job autonomy are vital, and that the loss of or failure to acquire job resources can lead to stress and burnout. The Self …

Investigating Fentanyl-Xylazine Interactions: Implications For Opioid-Induced Hyperalgesia And Affective Dysregulation In Rats, Alejandra R. Lujan

Electronic Theses, Projects, and Dissertations

The growing prevalence of fentanyl adulterated with xylazine presents a major public health concern, yet the behavioral and physiological effects of this combination remain poorly characterized. This study examined the effects of acute fentanyl administration, alone and in combination with xylazine, on opioid-induced hyperalgesia, affective behavior, and mortality in male and female Sprague-Dawley rats (n=80). Rats received four fentanyl injections (60 µg/kg) administered at 15-minute intervals, with or without xylazine (0, 0.1, 0.333, or 1.0 mg/kg), as well as a saline control condition. Pain sensitivity was assessed using a hot plate assay at 6.5, 12, 24, and 48 hours post-injection. …

This study addresses the gap by applying qualitative methodologies using a more balanced gender sample in the United States. Semi-structured interviews will capture participants’ experiences and perceptions of how excessive smartphone use affects their interpersonal relationships. Open-ended questions will explore smartphone use patterns, the …

Serotonin 7 Receptor Modulation On Measures Of Working Memory And Anxiety, Antonio Gutierrez

Electronic Theses, Projects, and Dissertations

Serotonin (5-HT) function is critical in the regulation and homeostasis of several neural systems. Alterations in 5-HT levels can directly impact the presence of neuropsychiatric disorders such as schizophrenia. With a wide range of 5-HT receptors, the potential impact each of these modulators have on behavior is important to better understand. The 5-HT7 receptor is the most recently identified 5-HT receptor. 5-HT7 receptors can be found in the thalamus, hypothalamus, and several areas of the hippocampus. Modulation of these receptors impact circadian rhythms, hormonal regulation and memory function. Previous research has that 5-HT7 antagonist compounds lead to conflicting results, highlighting …

We Are Fundamental (Somos Fundamentales): Examining The Perceptions Of Dei Initiatives Among First- And Second-Generation Latino Migrant Workers, Hector Aguilar

Electronic Theses, Projects, and Dissertations

Regarding organizational literature, diversity, equity, and inclusion (DEI) has been a topic of considerable interest due to an abundance of minority groups in the workforce, who are typically targeted by DEI policies. Within minority groups are migrant populations which make up a great deal of the working population, with Hispanic workers also accounting for a significant portion of that workforce. Organizational literature has had a great underrepresentation of the Hispanic working population who are an imperative group to study to better understand their attitudes, behaviors, perceptions, and outcomes, based on organizational DEI approaches. This can help promote researchers and organizations …

The Role Of Art-Based Pre-Performance Rituals For Collegiate Student-Athletes And Their Perceived Effects On Mental Preparation, Haylee P. Robinson

Undergraduate Honors Theses

This paper will explore whether collegiate student-athletes at the University of Northern Colorado (UNCO) engage with art-based pre-performance rituals (PPRs) and, if so, examine their perceived effects on mental preparation prior to competition. Research has discussed traditional preparatory routines (PRs)—breathing techniques, visualization, goal setting, and problem-solving—creating a gap for understanding how creative or symbolic rituals function in the realm of collegiate sports. Combining Clifford Geertz's (1973) anthropological framework of ritualized behaviors acting as “meaning-making systems” with empirical evidence supporting art therapy, this research positions symbolic art-based interventions as PPRs, helping athletes with focus, emotional regulation, and confidence prior to competition. …

Sleep Disturbances In Parkinson’S Patients With A History Of Head Injury, Melissa N. Pacheco

Electronic Theses, Projects, and Dissertations

Sleep disturbances are among the most prevalent and burdensome non-motor symptoms of Parkinson’s disease (PD), yet the contribution of prior traumatic brain injury (TBI) to these problems remains poorly understood. The purpose of this study was to examine whether the number and severity of lifetime head injuries predicted sleep disturbances in individuals with PD. Data from 3,055 PD patients enrolled in the Fox Insight study were analyzed, including 1,593 with a history of head injury. Participants completed self-report questionnaires assessing head injury history, motor and cognitive symptoms, and sleep disturbances. Generalized linear mixed models tested whether head injury history and …

Examining The Effects Of Boundary Management Practices Amongst Remote Workers In A Post-Pandemic World, Rosalia G. Casas

Electronic Theses, Projects, and Dissertations

With remote work on the rise after a world-wide pandemic, boundary management practices have been harder to establish for employees because of the high levels of integration that is seen when working from home. Identifying the impact that boundary management behaviors have on employees is important amongst remote workers because they are more often at risk for work-life spillover and conflict because of permeability between domains. This study looks at the relationship between work arrangements and employee outcomes such as work family conflict and job satisfaction with boundary preference and family supportive supervisor behaviors as moderators. Using linear regression models, …

Outcomes Associated With Childhood Parental Divorce: An Umbrella Review Of Meta-Analyses, Gabriel Xing Da Tan, Andree Hartanto, Ysabel Thereze Ang Guevarra, Angel K. M. P. Lee, Jing Jie Kenneth Koh, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna

Research Collection School of Social Sciences

Background: Childhood parental divorce has been consistently associated with a host of negative outcomes across multiple domains, such as socioemotional, behavioural, academic, and physical health, which can persist into adulthood. Despite extensive research on childhood parental divorce, the current literature lacks a systematic, integrated synthesis that clarifies which child outcomes are most consistently associated with parental divorce, as well as the potential moderators influencing these associations. Therefore, we conducted an umbrella review of meta-analyses to bridge this gap by consolidating the existing research and providing an exhaustive overview. Methods: Systematic searches were conducted across various databases and following a two-stage …

Perception Of Socioeconomic Status: A Meta-Analysis Of Manipulations, Jacinth Jia Xin Tan, Yong En Amos Tai

Research Collection School of Social Sciences

The causal effects of one’s socioeconomic status (SES) on outcomes are typically examined by experimentally manipulating SES self-perceptions based on one of three SES dimensions—absolute resource, relative resource, and general social position. We investigated the efficacy of these manipulations by systematically meta-analyzing their effects on SES self-perceptions. Based on 107 eligible samples (N = 26,203), manipulations of SES self-perceptions across the three SES dimensions were effective overall (g = 0.56–0.95). Explicit priming of absolute resource and relative resource manipulations comparing high versus low SES were consistently effective—although bias-corrected effects were attenuated—suggesting the importance of salient SES information and social comparisons. …

Log Off To Level Up: The Effect Of Social Media Hiatus On Goal Pursuit, Nekysha L. Y. Jalil, Yong Han Tan, Andree Hartanto, Eddie M. W. Tong

Research Collection School of Social Sciences

Concerns are growing that social media, with its constant notifications and attention-grabbing content, may distract individuals and hinder progress toward important goals. Despite its pervasive presence in our lives, the impact of social media on goal achievement has not been thoroughly studied. This within-subject experimental study aims to investigate the effects of social media hiatus (SMH), a short abstinence from social media usage, on goal pursuit processes. Participants (N= 107) completed daily diaries over three consecutive days of SMH and three days of regular social media use. SMH was manipulated by blocking participants’ access to multiple social media platforms. The …
