Chronic Administration Of Probiotic L. Rhamnosus Increases Anxiety-Like Behavior In Group-Housed Male Long Evans Rats, Parker Maddison Griff

Honors Theses

Early life stress is a risk factor for later development of alcohol use disorders and anxiety disorders in humans. Using rodent experimental models, we know that rats experiencing social isolation as early-life stress exhibit greater anxiety-like behavior and alcohol consumption than rats housed in groups. Examining potential preventive strategies, we investigated the effects of probiotics, which have previously been shown to decrease rodent anxiety-like behavior, on the relationship between early-life stress and anxiety-like behavior in rats. We hypothesized that probiotics consumption would decrease anxiety-like behavior in socially isolated rats, as well as in rats housed in groups. To our surprise, …

Differences In The Development Of Internalizing And Externalizing Behaviors In Offspring Of Depressed Mothers, Hannah Jackson

Honors Theses

This study examines the development of internalizing and externalizing behaviors in offspring raised by mothers with depression. Specifically, it explores mediating variables that explain differential associations of maternal depression with the offspring outcomes of internalizing problems and externalizing problems. Previous research has established that there is an association between maternal depression and the development of emotional and depressive (internalizing) behaviors as well as delinquency and antisocial (externalizing) behaviors in children. This study evaluates factors such as family instability, parental patterns and behaviors, and mother-offspring relationships in order to better understand the intervening processes that explain the link from maternal depression …

Wives’ Perceptions Of Husbands’ Housework And Parenting Contributions, Reilly Kate Kincaid

Honors Theses

Although husbands today may contribute more home and family labor than in previous decades, the type of contributions they make tend to be those of a “helpmate,” leaving the responsibility for organizing and managing housework and childcare to their wives. Gordon and Whelan-Berry (2005) found that husbands generally spent more time “doing” rather than “managing” in the household. The present study sought to examine working wives’ perceptions of how much their husbands “do” and/or “manage” in terms of housework and childcare. Results provide quantitative support for the high incidence of high-doing but low-managing husbands and shed light on the different …

How Academic And Extracurricular Workload And Stress Impacts The Mental And Physical Health Of College Students, Aidan Koch

Honors Theses

Academic workload and extracurricular involvement can be sources of stress for college students. Academic workload is characterized as the student's major, course work and future graduate school and/or career path plans. Extracurricular involvement can pertain from anything to intramural sports to being the President of a student organization. The current research sought to investigate changes in mental and physical health over a semester by examining physiological and perceived stress levels in college students, in conjunction with academic workload and extracurricular involvement. Previous research found an association between stress and physical health (Peer, Hillman, Van Hoet 2015). Studies have shown sympathetic …

Personality Types And Self-Reported Eating Habits, Thomas R. Lawler

Honors Theses

People with different personality types lead very different lifestyles; these personality types also affect the eating habits of an individual. Poor eating habits can lead to a myriad of health problems, including obesity and diabetes, while healthy eating habits can promote longevity. An associated problem is inaccurate reporting of eating habits by research participants and medical patients. While many studies have been conducted to examine the relationship between eating disorders and personality types, very few, if any, have examined the effects of personality types on actual eating habits as well as perceived eating habits. The proposed study will test for …

The Effects Of Adolescent Housing Condition And Voluntary Exercise On Alcohol Intake And Stress Response In Male Long-Evans Rats, Caroline Lynch

Honors Theses

Can regular exercise during adolescence, combined with living in a social environment, decrease the negative effects of chronic stress and lower alcohol intake later in life? The aim of this research is to answer this question using a rat model that introduces a novel behavioral intervention in the form of regular voluntary exercise in order to counteract the negative effects of chronic stress caused by socially isolated housing during adolescence. Chronic stress has been linked to the development of alcohol use disorders (AUDs) in humans, and this study attempts to both model and hamper this phenomenon in rats using voluntary …

The Effects Of Anxiety Induction On Olfactory Function In Healthy Young Adults, Lauren T. Olson

Honors Theses

There is significant overlap in the neural structures involved in the human limbic (emotion) and olfactory systems, and prior research findings have suggested both positive and negative associations between anxiety and odor detection sensitivity (threshold), odor identification accuracy, and odor hedonic ratings (Havlicek et al., 2012; Krusemark et al., 2013). However, knowledge about whether anxiety causes changes in olfactory perception remains unclear due to limited research findings. The present study aimed to extend the literature on olfaction and state anxiety by investing the impact of an anxiety induction on odor detection sensitivity, odor identification accuracy, and odor hedonic ratings. It …

Alcohol Deprivation Effect: An Investigation Of A Model Of Alcohol Dependence And Relapse Behaviors In Male And Female Long Evans Rats, Hanna J. Peterson

Honors Theses

The purpose of this study was to understand relapse behavior through a pre-clinical rodent model of relapse which models the important aspects of the human addiction and relapse condition, called the alcohol deprivation effect (ADE) model. It has been found to model alcohol addiction and relapse in rats and can therefore allow for further understanding of relapse behavior as well as allow for testing of the effects of various variables like stress or therapeutic drugs on relapse behavior. The model gives rats baseline access to ethanol and then allows them access to only water, called deprivation periods, and then gives …

Do Normative And Pathological Personality Traits Overlap? Exploratory And Confirmatory Factor Analyses Of The Neo-Pi-3 And Pid-5, Lisa Eileen Stone

Honors Theses

Historically, personality disorders have been conceptualized as qualitatively distinct clinical syndromes, based on operational criteria. Consistent with this model, ten distinct set personality disorder criteria are outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (American Psychiatric Association, 2013). However, debate persists about the clinical utility of this categorical model, with many (Krueger, et al.) researchers supporting a dimensional model that focuses on pathological levels of normative personality traits.

An exploratory factor analysis (De Fruyt et al., 2013) of the NEO Personality Inventory-3 (NEOPI-3; Costa & McCrae, 2010) and The Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, …

Caffeine Rush! Examining The Effects Of Caffeine On Spatial Working Memory, Alexander Lawriw

Honors Theses

Past research concerning caffeine and its effects on memory have yielded varying results. One study found that a 3-mg/kg dose of caffeine decreased reaction time during a selective attention task. However, this improvement was only found during a low display load, with no effect on reaction time occurring within a high display load (Lorist, Snell, Kok, & Mulder,1996). As such, the effects of caffeine may be dependent on a variety of other factors, such as the difficulty of the task at hand (Nehlig, 2004). This present study aimed to explore further the potential memory-enhancing qualities of caffeine with respect to …

Olfaction And Disgust As Predictors Of Elevated Perfectionism, Maia Mclin

Honors Theses

Odor detection and disgust sensitivity were once vital to survival by providing a means to assess if foods were safe for consumption. Along with odor detection and disgust sensitivity, obsessivecompulsive traits, such as checking, may have increased chance of survival by decreasing the likelihood of consuming contaminated foods leading to an evolutionary advantage (Rozin & Fallon, 1987). Current regulations that prevent the distribution of spoiled and contaminated foods in developed societies make these processes less necessary to survival today; as a result, obsessive compulsive traits that may have once been advantageous may now be pathological. Neural connections also suggest a …

Attitude Change Intervention For Victim Blaming Of Sexual Assault, Catharine Sciolla

Honors Theses

This research explores the possibility of an Attitude Change based intervention for victim blaming following and surrounding incidents of sexual assault and sexual violence. The study aimed at creating an intervention to successfully decrease and minimize victim blaming attitudes, beliefs, behaviors, and tendencies through a combination of internalization strategies, self-reference effects, and empirically supported attitude change methods. There were 149 participants who completed the study. Participants were tasked to complete a series questionnaires measuring Hostile sexism, Benevolent sexism, Just World Bias, Robbery Victim Blame, then complete the intervention, a brief educational reading and a self-generated response to a fictional rape …

Family Composition And Outcomes Following Parental Bereavement In Childhood, Ari M. Kagan

Honors Theses

The primary aim of this study is to compare the grief and stress related growth of individuals who have siblings and those who do not have siblings in the context of parental loss that occurred during childhood (before the age of 16). Adult participants provided self-report for the Traumatic Grief Inventory, Stress Related Growth Scale, and other related measures. We hypothesized only children who were bereaved during childhood would report higher levels of grief and lower levels of stress related growth compared to those with siblings who were bereaved during childhood. Multivariate analyses focus on grief and stress related growth …

Plant Power: The Impact Of Plants In The Classroom On Student Success And Well-Being, Elizabeth Pitts

Honors Theses

In this study we investigated if there is a relationship between the presence of plants in the classroom and student success and well-being. Past research has found that the presence of plants in the workplace and home improves attention capacity, satisfaction, well-being, affect, fatigue levels, and social connectedness. Participants were 177 college freshmen in an honors discussion-based course. These classes were located in one of two nearly identical classrooms, with the differentiating factor being the presence of two flower pots on plant stands with Snake Plants and Heart Leaf Philodendrons. The participants completed a paper-based survey that assessed classroom behavior, …

Trigger Warnings & Reactions To Literature: Sexual Victimization And Emotional Responses To Difficult Literature, Lynn E. C. Korsun

Honors Theses

Trigger warnings have been a cause for concern nationwide, and it remains unclear whether they truly protect students with varying histories of sexual assault trauma when exposed to triggering experiences. The sample consisted of 62 participants enrolled in an Introduction to Psychology course at Bucknell in the Fall 2017 and Spring 2018 semesters. Students responded to a three-part survey, filling out a prior sexual victimization scale, a life events checklist, a PTSD checklist, a distress scale, a research participation scale, and demographic questions in response to reading an emotionally distressing, “triggering” passage from Toni Morrison’s “The Bluest Eye.” Participants were …

Preferring Positivity : Age Differences In Judgments Of Learning And Memory For Emotionally-Valenced Words, Edie Sanders

Honors Theses

Many changes occur with age, including changes in emotion regulation and memory. The Socioemotional Selectivity Theory (Carstensen, 2006) posits that older adults tend to be more concerned with emotionally meaningful goals and therefore experience what is called the “positivity effect” with age. The positivity effect results in a bias in attention and memory towards positive stimuli over neutral and negative stimuli. Age-related changes also arise in memory monitoring, specifically in Judgments of Learning (JOLs), when individuals learn emotional words. We examined the presence of the positivity effect in memory and JOLs for positive, negative, and neutral words. Younger and older …

What's The Payoff? Parental Well-Being In Relation To Attachment, Interpersonal Goals And Parenting Style, Sherlee Q. Chandler

Honors Theses

Certain relational frameworks such as attachment, interpersonal goals, and parenting styles either found their roots in or have been studied in terms of the parent-child relationship. What often happens, however, is that researchers focus on how these constructs may affect child outcomes, without studying how they may impact the parents themselves. The current study sought to apply attachment and interpersonal goals in a parenting context, examine how they relate to the helicopter parenting style, and test all three constructs as predictors of parental need satisfaction. Parents of incoming college freshmen (N = 122) completed a survey comprised of the Experiences …

Active Shooters On Campus: Student Perceptions And Institutional Recommendations At The University Of Mississippi, Victoria Mulvey

Honors Theses

This study was part of a larger survey that examined crime on a college campus, attitudes about crime on campus, and knowledge about crime on campus. The objective of this study in particular was to evaluate students' knowledge and perceptions about active shooters on campus, and how these factors are influenced by gender. A cross-sectional survey was conducted with current students at the Oxford Campus of the University of Mississippi (N = 482). We hypothesized that female participants would show lower confidence in their ability to respond to (self-efficacy), and higher perceived likelihood and fearfulness of an active shooter event. …

University Belonging And Well-Being Across Contexts, Dakota Burton

Honors Theses

Belongingness has been presented in previous research as a fundamental need in which humans are motivated to seek out meaningful social interactions and contexts. In the current study, we sought to build on existing research examining belongingness in the university, by focusing on specific contexts in which first-year students are likely to meet belongingness needs. Participants in the current study comprised a sample of 299 University of Mississippi undergraduate, first-year students (23% male, 77% female). The study included seven questionnaires to measure the extent in which belongingness is related to well-being during the transition to college. The results of this …

Effects Of Emotion And Construal Level On Obesity Stigma, Peyton D. Curtis

Honors Theses

We conducted the present study to determine how emotion and construal level contribute to obesity bias. Specifically, we examined if different emotions, such as disgust, sadness, and happiness, played a role in several different judgments of an obese versus thin individual: 1) general impressions, 2) supporting a friend, and 3) endorsing personal versus biological/environmental causes for weight. We also investigated whether a self me construal or collective we construal influenced these judgments. We additionally considered whether emotion and these construal levels would interact to influence such judgments. The current work found that emotion and construal level did not interact to …

Posttraumatic Stress Symptoms In College Students: An Examination Of The Association With Emotion Regulation, Posttraumatic Growth, And Nonsuicidal Self-Injury, Cayla S. Hari

Honors Theses

The present study aimed to investigate the relationship between posttraumatic stress symptoms, nonsuicidal self-injury, emotion regulation, and posttraumatic growth in college students. One-hundred and fifty-three participants, aged 18-57, completed self-report measures about their experiences with posttraumatic stress symptoms (PTSS), nonsuicidal self-injury (NSSI), emotion regulation (ER), posttraumatic growth (PTG), and potentially traumatic events (PTEs). In line with hypotheses, results indicated a significant positive correlation between PTSS and both NSSI and PTG. Contrary to predictions, no significant relation was seen between ER and PTG and ER did not moderate the relationship between PTSS and PTG. A post hoc correlational analysis assessing potential …

Stress In College Students: Associations With Anxiety And Perfectionism, Emory Hamblin

Honors Theses

Psychosocial stressors are prevalent in the workplace and academic environment largely due to emotional responses from rising conflict, unattainable demands, or a decreased sense of control. An individual's perception of stress is interrelated to the characteristic of perfectionism and the level of anxiety one possesses. Stress is commonly associated with adverse circumstances, and perfectionism is characterized by the setting of unrealistically high standards accompanied by a personal and social standard, attitude, or philosophy. Anxiety is characterized by increased physiological arousal, inhibition of ongoing activities, and a change in individual priorities. Previous studies have examined anxiety's relation to stress-invoking stimuli, but …

Analyzing The Use Of Expressive Writing Among College Students, Grace Ann Wilbanks

Honors Theses

This is among the first studies to investigate the naturalistic use of expressive writing in college students. To do so, 255 undergraduate students from the University of Mississippi anonymously completed an online survey. Participants first answered basic demographic questions followed by questions assessing their sadness or depression, happiness, and overall adjustment in college. Next, participants responded to questions concerning expressive writing and ways in which they handled demands of college. Finally, respondents then completed a well-researched, standardized measure of depression, anxiety, and stress. Independent-samples t tests revealed that students who engaged in expressive writing demonstrated lower mean levels of sadness …

Growth Mindset And Persistence In Children's Creative Performance, Tiffany Gerlinger

Honors Theses

Motivation literature regarding children's academic achievement is quite extensive and can typically be separated into two mindsets: growth mindset and fixed mindset, which vary on their level of persistence (i.e., effort toward a task, Dweck, 2006). Individuals with a growth mindset find persistence is useful because they believe their abilities can change through hard work. Individuals with a fixed mindset find persistence is not useful because they believe their abilities cannot change with hard work. In the domain of creative achievement there is a lack of research on mindset and persistence during creative performance. Research shows that adults underestimate the …

Examination Of Dental Distress And Anxiety-Related Vulnerability Factors, Sydney Olson

Honors Theses

Apprehension towards dental services has been documented for decades, and despite modern scientific advances, dental anxiety and phobia continue to adversely affect individuals' oral and mental health. Furthermore, the prevalence of dental distress is estimated to range from 8% to nearly 30% among community samples. Given the prevalence and impairment of dental distress, understanding the underlying mechanisms is pertinent to finding more effective treatments. In particular, transdiagnostic processes that may be implicated in dental distress include anxiety sensitivity (AS), pain sensitivity (PS), and distress tolerance (DT). As such, the aims of the current study were 1.) to characterize dental distress …

Honors Theses

The prevalence and severity of mental health disorders on college campuses has been increasing nationwide. This review aims to address some of the prevalent mental health issues that continuously plague college students today. Recent trends in college student mental health are analyzed as well as literature regarding common disorders including depression, anxiety, and bipolar disorder. A comparison of honors and non-honors students is provided to contribute to an otherwise lacking area of research surrounding honors student populations. Effective practices and policies for colleges and universities to incorporate into their counseling services are also considered, with viable goals centering on the …

A Comparison Of Three Reading Interventions For Three Children With Autism Spectrum Disorder, Alexandra D. Utley

Honors Theses

Brief experimental analyses (BEA) have been used in the present literature to identify the most effective reading strategy in increasing oral reading fluency (ORF) for typically-developing students. The current researcher extends the research by implementing three reading intervention to three children with autism spectrum disorder (ASD) to study whether a BEA is effective in identifying the most effective reading intervention for children with developmental disabilities. There were three interventions implemented throughout the duration of the study: Repeated Reading, Phrase Drill, and Contingent Reinforcement. Additionally, the present study implements an extended intervention (EA) to test the accuracy of the BEA results. …

Exploring The Moderating Effects Of Drinking Context On The Relationship Between Harmful Drinking And Risky Sexual Behaviors Among College Females, Lauren A. Gardner

Honors Theses

Females are engaging in harmful amounts of drinking at higher rates than ever before. Because these rates are increasing, studying harmful drinking in the college female population is imperative. Previous studies have noted that an increase in harmful drinking correlates positively with an increase in risky sexual behavior. Although these correlations are evident, no previous study has looked at drinking context as a moderator between these two variables. The current study examined the degree to which drinking context moderates the relationship between harmful drinking and risky sexual behavior in college females. This study consisted of 387 female college students ages …

Comparison Of Suicidality Among Heterosexual And Sexual Minority Individuals, Ashley R. Pate

Honors Theses

Previous research suggests that sexual minority individuals have a higher risk of suicidal ideation and suicide attempts than do heterosexual individuals. Little research has been done to determine what may cause these differences and how living in a conservative region may contribute to it. This study sought to compare risk factors for suicidal ideation among heterosexual and sexual minority college students in southern Mississippi. To do so, suicidal ideation was examined, as well as thwarted belongingness (TB) and perceived burdensomeness (PB) – two robust predictors of suicidal ideation. It was hypothesized that sexual minorities would have elevated TB, PB, and …
