Sleep Duration Is Associated With Caudate Volume And Executive Function, Nicole Jones

Honors Theses

The ineligible role of the caudate nucleus in sleep has been implicated throughout multiple scientific studies. Previous literature has shown that greater caudate volume is associated with longer habitual sleep duration in older adults- ranging from 55 years of age and up. However, the association between sleep duration and caudate volume remains unknown in the younger population. In this study, we examined the caudate volume in youth to older adults (10 to 85 years old) with a greater sample size (N=464) to increase statistical power. The volumetric size of the caudate nucleus showed significantly positive association with habitual sleep duration, …

Perceiving The Poster: How Suspicion Of Motives May Impact Perceptions Of Potential Allies Engaging In Online Activism, Kathrina Z. Durante

Honors Theses

Social media posts signaling support for various social and racial justice movements have emerged as an important aspect of social media use. However, little research has investigated how these posts and the social media users behind them are perceived by members of disadvantaged groups﹘those the messages are presumably intended to “help.” Though the post’s content and poster’s identity are likely important, the primary aim of this study is to investigate an individual difference variable in the perceiver, specifically disadvantaged group members’ Suspicion of Motives Index (SOMI) scores, which measure a general tendency to perceive White individuals’ attempts at non-prejudice to …

Why Diversity Is Not Enough: Perceptions Of University Diversity, Equity, And Inclusion Initiatives Predict Institutional Belonging, Mckennah Lauber

Honors Theses

Belonging, including feelings of being valued in a larger institutional space, is important to student overall well-being. For students of color attending Primarily White Institutions (PWIs) (and other historically marginalized group members), institutional belonging maybe partially dependent on how they perceive diversity, equity, and inclusion (DEI) initiatives. This study aims to assess individual differences in how DEI initiatives are experienced by students at PWIs in order to better understand how experiences of DEI initiatives on campuses may differentially impact students of color compared to White students. Belonging for students of color was found to be contingent on their perceptions of …

Taking The Social Out Of Social Media: Social Media Induced Loneliness As A Mechanism For Elevated Depression During The Pandemic, Samara Rosen

Honors Theses

During the COVID-19 pandemic health protocols limited in-person interactions, interrupting the undergraduate experience and prompting students to find virtual ways to connect with their peers. A key goal of this study was to assess whether college students’ social media use was a viable replacement for in-person interactions during the pandemic, reducing risk for psychological difficulties that ordinarily accompany social isolation. The purpose of the present study was to evaluate loneliness as a potential mediator underlying the longitudinal relationship between social media use and depression. Self-report data were collected in November 2020 (T1), February 2021 (T2), and May 2021 (T3). The …

Maladaptive Social Cognitions And Peer Victimization In Elementary-Aged Students, Katelyn Szarko

Honors Theses

Among elementary-aged students, peer victimization is common and is associated with psychological maladjustment and poor academic achievement. Students with maladaptive social cognitions, like low social competence and low perceived control, are more likely to be victimized, but having a supportive teacher and/or a positive classroom climate might help to mitigate this association. This study aimed to answer the question of whether teacher support and classroom climate protect against peer victimization for students with maladaptive social cognitions. It was hypothesized that teacher support and classroom climate will separately moderate the link between social competence/perceived control and subsequent peer victimization such that …

Justifying Antipathy?: Examining Racialized Perceptions Of Incarceration And Support For Mental Healthcare In Prisons, Jared Brassil

Honors Theses

The current U.S. criminal justice system has a disproportionate number of people suffering from mental illness. Additionally, many of these prisons not only lack the ability to properly treat these individuals, but in some cases may even worsen the problem. Public support, and importantly whom the public thinks the prototypical prisoner is, is important to know when advocating for reform. This research aims to investigate whether or not racialized perceptions of the U.S. criminal justice system impact support for mental healthcare reform in prisons. Given the exploratory nature of this work, potentially relevant individual difference variables are also investigated. An …

Generative Beauty: How Engaging With Beauty Sparks Transformation, Rebecca Byrd Musser

Honors Theses

“Be the change you wish to see in the world,” declared Mahatma Gandhi. There is a profound awareness of the need for change as individuals reflect on the impact of global and system challenges as well as community challenges. People cannot just “be the change” until they themselves are first changed. Beauty is a powerful catalyst for change that begins with the individual, expanding to the community. To solve community problems, program designers must find a way to unleash untapped creativity. This study explores the impact of engaging beauty via the arts (paintings, Mary Oliver poetry, and The Lark …

Social Science Researchers' Perceptions Of Inclusive Research Practices For Transgender And Gender Diverse Communities, Christen Seyl

Honors Theses

Social sciences research has historically excluded or marginalized of transgender and gender diverse (TGD) people. Although TGD affirming research materials can help improve relationships with TGD communities, these sorts of materials are not standard practice. The present study aimed to determine what factors influence social science researchers’ (SSR) willingness to incorporate affirming practices into their research. We hypothesized that more culturally competent SSR will view TGD affirming research materials as more affirming and be more willing to use similar materials in their work. In this study, SSR (n = 32) viewed and rated affirmation and willingness to use five affirming …

The Effects Of Survival, Pleasantness, And Storytelling Conditions On True And False Memory Recollection, Rachel Daniels

Honors Theses

The purpose of the present study was to analyze the extent to which various processing scenarios influenced participants' rates of true and false memory recollection. Participants were placed in one of three conditions, storytelling, survival, or pleasantness, and then studied a list of common nouns. They were then instructed to comment on the words in a specific manner depending on the condition to which they were randomly assigned. Following this, participants completed a math distractor task, and were then asked to complete a free recall test for the previously studied words. The results indicated that participants in the storytelling condition …

Timing Is Stressful: Do Listeners Combine Meaning And Rhythm To Predict Speech?, Molly Mcleod

Honors Theses

English and other languages such as German are stress-timed languages: the timing of the speech is determined by stressed and unstressed syllables, providing structure for sentences. While natural speech is not generally metrically regular, like in Shakespearean poetry, it still conveys timing cues through stress. Prior research has found that metric regularity enhances the processing of words (Rothermich et al, 2012), potentially because it attunes listeners’ attention to the predictability of stressed, and therefore important, syllables. Other work (e.g., Rogers, 2017) has suggested that predictability in the form of semantic associations (e.g., hearing “barn” facilitates understanding of “hay”) is a …

Does Adhd Strengthen The Relationship Between Depression/Anxiety And Avoidance?, Ryan Wigginton

Honors Theses

Objective: Attention-Deficit/Hyperactivity Disorder (ADHD) is a diagnosis often

comorbid with depression and anxiety-related disorders. Research is also indicative of a relationship between ADHD, depression, anxiety, and avoidance-related behaviors. I hypothesize that the relationship between ADHD and avoidance will be moderated by symptoms of depression and anxiety in neuro-typical college students that have not received a clinical mental health diagnosis. Method: 101 college students at the University of Richmond attended a baseline visit with a research assistant and completed baseline scale measures for symptoms of ADHD, depression, generalized anxiety, and avoidance. I used multiple regression and Hayes’ PROCESS program to analyze …

Focus On Hyperfocus: How Adhd Symptoms Impact Difficulty With Disengagement And Inattention, Cameron Mckendrick

Honors Theses

Attention Deficit Hyperactivity Disorder (ADHD) is a chronic neurodevelopmental disorder marked by patterns of inattention and hyperactivity. Hyperfocus (HF) is a concept that has heavily been associated with ADHD; however, it is not part of any diagnostic criteria and the literature pertaining to HF is rather underdeveloped. The present study adds to existing research by examining how HF differentially impacts ADHD populations compared to non-ADHD populations. The three main hypotheses explored in this paper are that ADHD positively predicts HF in the moment, HF in the moment negatively predicts inattention in the moment, and that the correlation between HF and …

Peoples’ Perception Of Race-Based Microaggressions As A Function Of Their Background And Beliefs, Emily Huesman

Honors Theses

This current study’s aim was to further address microaggressions and how people perceive these “micro” aggressions based on Political identification, support for the Black Lives Matter movement, and their beliefs surrounding White privilege. Recent literature has shown that racial discrimination in any form can be incredibly detrimental to mental health, however, this study addresses the every-day microaggressions and subtle forms of racism that Black people experience every day and delves further into why these “smaller” forms of racism might not be addressed. This study used a Qualtrics survey to obtain both qualitative and quantitative data on peoples’ beliefs surrounding the …

Falling For Moses: The Role Of Stroop Inhibition And Language Expertise, Isabella Holmgren

Honors Theses

When presented with the question, “How many animals of each kind did Moses take on the Ark?”, people often respond “2”, despite knowing that Noah is the Biblical figure who is said to have taken animals on the ark. This phenomenon where people fail to detect inaccuracies in text has come to be known as the Moses Illusion (Erickson & Mattson, 1981). The current study was designed to investigate Moses illusion rates in a multiple-choice format. Further, participants were assessed on two cognitive constructs: language experience and cognitive inhibition. Results showed robust rates of the Moses illusion using the multiple-choice …

Barriers To Care, Depressive Symptoms, And Moderating Factors Among Patients With Esrd, Amarachukwu O. Nwangwu

Honors Theses

End-Stage Renal Disease (ESRD) is the fifth and final stage of Chronic Kidney Disease (CKD) and has been reported to have the highest prevalence rate in the United States, with about 2,242 cases per million in the total population in 2017 (Johansen et al., 2021). Current studies document a high prevalence of depression among patients with ESRD which may lead to increased mortality (Shirazian et al., 2017). Additionally, barriers in access to care, which may be understood as the barriers that prevent individuals from seeking mental health services, has been linked to increased levels of undertreatment (Clement et al., 2012). …

Hometown Diversity And Race Essentialism: The Role Of Interracial Friendship Quality, Junming Zhang

Honors Theses

The purpose of this study was to investigate associations between high-quality interracial

friendships and race essentialism among college students who perceived differing levels of racial diversity in their hometowns. Participants, who were recruited from a small, private university in the southeastern United States, included 84 juniors and seniors who reported having at least one other-race close friend. Participants completed a web-based survey about their hometown diversity, friendship quality, and race essentialism. Results from multiple regression analyses revealed two significant interaction effects between hometown diversity and two measures of interracial friendship quality: intimate disclosure and affection. Findings indicated that higher intimate …

How Does Movement Impact Originality In A Divergent Thinking Task?, Molly B. Fontenot

Honors Theses

Research has suggested that original thought can be affected by movement. However, this research has primarily focused on children, with embodied creativity work lacking in adult populations. This study aimed to examine the impact of movement on the generation of original ideas within divergent thinking tasks in adults. To study this, participants first completed a baseline divergent thinking task asking participants to come up with as many novel uses for a common item. After baseline, participants were randomized into three different testing groups that were encouraged to engage in different types of movement during the divergent thinking task: 1) meaningful …

Metacognitive Function In Moderate To Severe Traumatic Brain Injury, Grace Amadon

Honors Theses

Traumatic brain injury (TBI) is an injury to the brain caused by a bump, blow, jolt to the head. Individuals with TBI demonstrate decreased awareness of their own potential deficits and functional abilities. These deficits have critical implications for recovery as self-awareness is important for those recovering from TBI in the implementation and engagement of rehabilitative processes after TBI. The following study analyzed 18 individuals with TBI approximately 11 years post injury to document metacognitive functioning after injury. Participants completed a metacognitive working-memory paradigm where they made judgements of their future and past performance on identifying a target shape and …

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 …

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

Honors Theses

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 …

Autistic Personality Traits And Processing Of Ironic Language, Jaclyn Opie

Honors Theses

Whereas typically developing adults tend to show processing differences for ironic versus literal language, recent research has demonstrated that adults with Autism Spectrum Disorder do not show a difference. Building on these findings, the present study examined whether similar effects would emerge in a sample of college students who were assessed on autistic personality traits. Through an eye tracking during reading experiment, participants read sentence contexts in which factors of emotional language, ironic versus literal language, and sentence perspective were manipulated. Results showed that participants who had a low degree of autistic traits somewhat replicated the two-stage processing model of …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

The Effect Of Story Processing On Memory Performance, Anna Miller

Honors Theses

The purpose of the present study was to determine how recall performance following story processing compared to both survival processing and pleasantness processing. Participants were provided with a set of instructions depending on the condition they were in, narrative, survival, or pleasantness. Following this, participants rated the words one at a time, completed a brief distractor task, and then attempted to remember as many items as they could. The primary results demonstrated that narrative processing may provide a recall advantage similar to survival processing. These results suggest that similar underlying mechanisms may enhance recall in both sets of instructional conditions.

Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson

Honors Theses

Background: Our recent experimental work demonstrated that high-intensity acute exercise improved veridical (true) memories and also increased the rate of false memories. The present experiment was designed to re-evaluate these effects for replication purposes. We also extend this literature by evaluating whether these effects are influenced by the timing of acute exercise. Methods: The sample included young adults (N=37; M_age = 21.16 years). We employed a three-condition, within-group, counterbalanced controlled design, consisting of two exercise conditions and a control condition. The exercise conditions involved a 15-minute bout of high-intensity acute exercise. These conditions included the bout of …

The Role Of Action In Affordance Perception Using Virtual Reality, Ashley J. Funkhouser

Honors Theses

Space perception in virtual reality (VR) is distorted. Does action in conjunction with an avatar's presence improve perception in VR? Participants judged whether a virtual ball was within reach. Condition 1 was perception-only, where the participant was not allowed to move nor could see their arms. Condition 2 was perception with nonvisible action, where the participant could move their real arm to reach but could not see an avatar representation of the arm. Condition 3 was perception with visible action, where the participant could move and see a virtual hand that corresponded to the actual arm movement. Participants overestimated their …

A Comparison Study Of Naming, Kassidi Krzykwa

Honors Theses

Bidirectional naming is the ability to acquire a listener response or tact for a stimulus and then emit the other operant without further training. Incidental naming refers to the ability to emit the listener response and tact for the item without direct reinforcement after just being exposed to the name of the item. The development of naming could allow a child to learn more readily from the natural environment. However, it is unclear if bidirectional naming and incidental naming are two separate skills, or if one is potentially a prerequisite for the other. For this project, procedures outlined by Greer …

Changes In Hemodynamic Response To Faces, Scenes, And Objects In A Visual Statistical Learning Task: An Fmri Analysis, Aaron T. Halvorsen

Honors Theses

Learning causes changes in brain activity and neural connections. Statistical learning is an implicit learning process that involves extracting regularities from the environment and finding patterns in stimuli based on their transitional probabilities. The following study describes an attempt to elucidate temporal changes in hemodynamic activity for three category-specific brain areas using functional magnetic resonance imaging (fMRI). Blood oxygen-level dependent signal (BOLD) responses were collected while subjects viewed faces, scenes, and objects with high and low transitional probabilities in an fMRI scanner. We expected brain activity to show a temporal shift in timing of activation when comparing BOLD signal responses …

Increasing The Frequency Of Tutors' Reinforcement Of Compliance Behaviors, Sruthi Rameshkumar

Honors Theses

Abstract

Compliance behaviors occurring prior to the delivery of an instruction, such as handing over preferred items, making eye contact, and folding hands in the ready position help prepare students for success in discrete-trial training (DTT) interventions. These behaviors are usually taught in early intervention with a continuous reinforcement schedule, but once they are mastered, they are rarely revisited or maintained. Without intermittent reinforcement of these behaviors, they are likely to decrease in frequency and may lead to the use of restrictive or intrusive methods to gain compliance during DTT sessions. The current study used a multiple-baseline across participants design …

Effects Of Diagnostic Labels On College Students' Perceptions Of Children With Autism Spectrum Disorder, Sarah Grace Cowell

Honors Theses

The Center for Disease Control reports current research that indicates 1 in every 68 children in the United States has the diagnostic label of Autism Spectrum Disorder. Research literature of the past 20 years has warned of the possible dangers of labels, such as Autism Spectrum Disorder, and the potentially negative impact these labels can have on an individual throughout a lifetime.

This project investigates college students' perceptions of the label Autism Spectrum Disorder in regard to a child's educational potential and later employment. College students viewed a four-minute video of a child in solitary play. One-half of the participants …

Increasing Waiting And Turn-Taking Among Preschool Aged Children With A Verbal-Delay Diagnosis, Alexa Hill

Honors Theses

The goal of this thesis was to create and implement an intervention that used errorless teaching and focused on increasing a sharing and waiting response for a student who had a verbal delay diagnosis. The two students involved in the project were both two-year-olds who attended an early childhood special education (ECSE) classroom with other preschool-aged children who had similar diagnoses. A single-subject simple baseline design was used and involved several phases designed with multiple responses to show the effectiveness of icons to facilitate sharing among two non-verbal students. Each response was prompted (when necessary) and they were all reinforced …
