Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Acute And Chronic Oral Administration Of Cannabidiol-Dominant Cannabis Products: Sex- And Formulation-Dependent Effects On Anxiety-Like Behavioral Patterns In Rats, Carlos R. Maestas-Olguin

Psychology ETDs

Interest in the anxiolytic-like effects of cannabidiol (CBD), the non-intoxicating phytocannabinoid found within the genus, Cannabis, has grown significantly in recent years. However, preclinical investigations of CBD’s anxiolytic potential often elect to forgo translationally relevant models that maximize external validity in favor of greater internal and mechanistic validity. As a result, the effects of relatively low dose (< 3mg/kg) oral CBD administration on anxiety-like behaviors are not yet fully characterized. The present studies examined the impact of two orally delivered CBD-dominant cannabis products – a “full-spectrum” formulation derived from the whole plant and a CBD isolate derived from the same chemovar – on innate defensive behaviors exhibited by adult male and female rats in various tests of anxiety. Results indicated that acute and chronic low dose oral CBD administration attenuated anxiety-like behavior in rats, regardless of sex or formulation. These findings extend the growing corpus of literature describing anxiolytic-like effects of CBD.

Academic Anxiety, Anxiety Sensitivity, And General Mental Health In Collegiate Student-Athletes, Finley Gabrielle Elkins Sims

Theses and Dissertations

Collegiate athletes’ mental health is on the decline, and they have unique experiences that can influence the prevalence of mental health struggles. This study examined academic anxiety, comorbid forms of anxiety, and predicting factors in 187 collegiate student-athletes across 29 U.S. colleges. Athletes had significantly higher levels of academic anxiety and general anxiety compared to a college nonathlete population. There were significant gender differences in athletes, with females having greater levels of anxiety sensitivity, academic anxiety, sport anxiety, general anxiety, depression, and a history of depression than male athletes. Gender, history of depression, anxiety sensitivity, and depression were significant predictors …

An Experimental Test Of Mental Health Help-Seeking Intentions As A Function Of Demographics And Disorder Type, Alyssa Hartley

Psychological Science Undergraduate Honors Theses

The current study sought to understand help-seeking behaviors for diverse psychological disorders across different demographic groups. Previous literature finds that help-seeking behaviors are greater in non-minority women in higher socioeconomic statuses, and greater for neurocognitive disorders. This study focuses specifically on university students (N= 276). Participants took diagnostic measures and then were told their scores were clinically elevated for either anxiety or ADHD. Participants were then asked qualitative questions regarding their help-seeking intentions. Findings that were consistent with previous literature are that women were more likely to help-seek than men, and participants in the ADHD condition were more likely to …

The Effectiveness Of Weighted Blankets As A Sleep Promoting Behavior: A Quasi -Experimental Study, Irish Amalia, Sali R. Asih, Inge U. Wiswanti, Ina Saraswati

Psychological Research on Urban Society

Sleep is crucial to the overall well-being of individuals. Sleep deficiency can lead to various physical and mental health issues, including more severe insomnia, anxiety, and depressive symptoms. Improving sleep quality is often emphasized through sleep hygiene. An emerging nonpharmacological intervention is the use of weighted blankets, which apply deep-pressure stimulation to promote feelings of relaxation, comfort, and security similar to a gentle hug. This study explored the effects of weighted blankets on sleep quality and symptoms of insomnia, anxiety, and depression. Thirty participants (M = 33 years, SD = 9.13) used weighted blankets for 14 nights. They completed the …

The Psychological Effects Of Solitary Confinement On Incarcerated Individuals: A Systematic Literature Review, Lara Z. Parkes, Jonathan C. Dowers

Selected Student Publications

This systematic literature review looks at previous research that explores the possibility of a correlation between solitary confinement and the presence of mental illness within those isolated inmates. Twenty percent of prison inmates experience isolation for up to twenty-two hours per day with restricted social interaction and limited amenities (Hagan et al., 2018; Ryan & DeVylder, 2020). Certain inmate demographics are more likely to be sent into isolation in an effort to protect themselves or others, including members of the LGBTQIA+ community, the developmentally impaired, and the mentally ill. However, this practice often has the opposite of its intended effect. …

The Association Between Coping-Motivated Drinking And Alcohol-Related Consequences., Jacob D. Salser, Ian A. Mcnamara, Ryan W. Carpenter

Undergraduate Research Symposium

ABSTRACT. Background: College students’ alcohol use is an important topic of research. Past research indicates that people who drink to cope are at a higher risk for alcohol-related consequences compared to other drinking motives (i.e., enhancement, social, or conformity motives). This project aims to analyze drinking motives, specifically the subscales of coping-anxiety motives and coping-depressive motives, and their association with alcohol-related consequences in a unique population. In addition, the moderating effects of stress will be tested.

Methods: The data for this project was collected through a survey that was given to students (N=176) at the University of Missouri …

The Benefits Of Art Therapy On Stress And Anxiety Of Oncology Patients During Treatment, Helen Shiepe

Expressive Therapies Capstone Theses

Within the last ten years research on art therapy and its positive impact on oncology patients’ stress and anxiety during treatment has been minimal. Oncology patients whether they are children or adults when diagnosed experience similar reactions due to their diagnosis, treatment, and in some cases end of life care. The current question is whether or not art therapy does have a positive impact on decreasing the stress and anxiety with oncology patients while undergoing treatment. Deane, Fitch & Carmen (2000), discussed art therapy as a healing art that is “intended to integrate physical, emotional, and spiritual care by facilitating …

In Covid-19 Health Messaging, Loss Framing Increases Anxiety With Little-To-No Concomitant Benefits: Experimental Evidence From 84 Countries, Charles A. Dorison, Et. Al., Andree Hartanto

Research Collection School of Social Sciences

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., “If you do not practice these steps, you can endanger yourself and others”) or potential gains (e.g., “If you practice these steps, you can protect yourself and others”)? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message …

The Impact Of Mindfulness Practices In Teachers, Shawn M. Martin Hettinga

ATU Theses and Dissertations 2021 - Present

Mindfulness training has been identified as a promising means for cultivating social and emotional competencies and reducing stress. The purpose of the quantitative pre-post study using convenience sampling of educators in a rural K-12 in the Arkansas River Valley was to examine whether teachers’ participation in mindfulness activities were associated with changes in levels of stress, anxiety, depression, and job satisfaction. The study used the Depression, Anxiety, and Stress Scale (DASS-21) and the Job Satisfaction Survey (JSS) and measured the responses from novice (0-3 years) and experienced (4+ years) teachers.

The Relationship Between Social Media Use And Depression And Anxiety Symptoms During Covid-19, Tene'sha L. Crews, Christina Sheerin

Undergraduate Research Posters

The rise of the coronavirus (COVID-19) pandemic has caused a global surge in exposure to disaster and crisis-related media. Increases in poor mental health outcomes such as anxiety and depression, are associated with increased exposure to such media content (Abbas et al., 2021; Riehm et al., 2020; Zhao & Zhou, 2020). In recent years, social media has become one of the most widely used sources for news; approximately 48% of adult Americans receive their news from social media (Pew Research Center, 2021). During the COVID-19 pandemic, there has been an increase in social media use due to social distancing and …

Covid-19 Vaccine Related Anxiety Partially Mediates The Association Between Covid-19 Related Anxiety And Student Adjustment To College During The Pandemic, Hanh Nguyen

Dissertations and Theses

The COVID-19 pandemic caused severe disruptions to the education of millions of college students, who were forced to adapt to sudden changes in living and learning environments. In this study, we sought to investigate two different dimensions of anxiety that were specific to the pandemic – COVID-19 related anxiety and COVID-19 vaccine anxiety – hoping to pinpoint the relationship between these two variables and students’ ability to adapt to college. Specifically, using cross sectional survey data during three semester waves (Spring 2021, Fall 2021, and Spring 2022) we hypothesized (1) a decreasing trend across time in both COVID-19 related anxiety …

The Effects Of Venlafaxine And Voluntary Exercise On Chronic Unpredictable Stress Induced Anxiety, Marly Mcgowan

Senior Independent Study Theses

Anxiety disorders can impair cognition and emotional control, particularly in the face of novel situations, which is concerning due to the high prevalence of such diagnoses. Exposure to unpredictable chronic stress can provide a way to induce anxiety-like behaviors in rodents by disrupting the stress response systems, including the HPA axis and autonomic nervous system. Pharmacological treatments, including SNRIs like venlafaxine, and voluntary exercise are both anxiolytic treatments that can alleviate the impacts of chronic stress. Using unpredictable chronic stress to mimic the human condition, and exposure to venlafaxine and exercise to mitigate the stress, the open field and elevated …

A Critical Review On The Moderating Role Of Contextual Factors In The Associations Between Video Gaming And Well-Being, Andree Hartanto, Verity Yu Qing Lua, Frosch Yi Xuan Quek, Jose C. Yong, Matthew H. S. Ng

Research Collection School of Social Sciences

The appeal of video gaming has undoubtedly withstood the test of time. In view of its increasing popularity, lay people and researchers alike have taken an interest in the psychological consequences of video gaming. However, there seems to be a paradox associated with the effect of video gaming on gamers' well-being—namely, while most video game players cite “fun” as their motivation to play video games, video games continue to hold a notorious reputation among some researchers for being detrimental to mental health and emotional well-being as measured by indicators such as happiness, perceived stress, anxiety, and depressive symptoms. We suggest …

Hidden Links: Trait Anxiety And The Hostile Attribution Bias, Sarah Gracia

Honors Program Theses and Projects

The hostile attribution bias (HAB) is a tendency to interpret malevolent intentions when confronted by ambiguous actions of others. Much research has been conducted to examine the relationship between HAB and aggression, but little on HAB and other personality traits; further, comparatively little research has examined whether strategies like metacognition can reduce HAB. This project examines the relationship between HAB and trait anxiety and whether a metacognitive manipulation reduces HAB. In Study 1, participants filled out a survey questionnaire containing the Beck Anxiety Inventory to measure trait anxiety and both the W-SAP and the hostility section of the Aggression Questionnaire …

Frontal Alpha Wave Asymmetry In Regard To Affect, Monica Leigh Sewell

All Master's Theses

This study examines frontal alpha brain wave asymmetry (FAA) in relation to emotion processing. Previous research has shown that differences between left versus right FAA could exhibit a neurological marker for emotional intelligence (EI), mental health, and stress. Behavioral data were collected using Profile of Emotional Competence Questionnaire, Perceived Stress Questionnaire, Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7. This was followed by a series of resting EEG recordings. This study hypothesizes that participants who are mentally healthy, have higher EI scores and lower stress will display greater left FAA. The hypothesis is partially supported; participants with depression had greater …

Assessing Sex Differences In The Effects Of Short-Term Rem Sleep On Anxiety- And Depressive-Like Behaviors In Rats, Nadia Meshkati

Seton Hall University Dissertations and Theses (ETDs)

Findings from both human and animal studies suggest rapid eye movement (REM) sleep disturbances following a traumatic event can lead to inability to extinguish the fear association, and eventually influence the development of post-traumatic stress disorder (PTSD). Additionally, research has demonstrated that sleep disruptions, including REM sleep deprivation (RSD), increases anxiety- and depressive-like behaviors and states in animals and people, with evidence of sex differences. Furthermore, it has yet to be determined whether short-term RSD, a more natural animal model of PTSD, can influence affective state of subjects. The present study applied short-term RSD to investigate sex differences in the …

Confidence In Academic Testing: The Effect Of Induced Checking And Anxiety On University Students' Emotional Responses To, And Performance In, Academic Challenge, Elijah Bruner

All Master's Theses

Academic tests such as the American College Testing (ACT), Scholastic Aptitude Test (SAT), and National Assessment for Educational Progress (NAEP) have been used to assess academic aptitude. Research suggests that both test anxiety and test emotions (positive and negative) influence academic performance. The purpose of this study was to investigate the effects of test anxiety and uncertainty (i.e., re-checking items) on performance and test emotions. It was hypothesized that induced checking and participant anxiety would negatively predict performance and positive testing emotions, and positively predict negative testing emotions. It was also hypothesized that induced checking and anxiety would interact, with …

The Relationship Between Anxiety, Mind Wandering And Task-Switching: A Diffusion Model Analysis, Andree Hartanto

Dissertations and Theses Collection

Although the negative impact of anxiety on task-switching has been documented, little is known about the extent or mechanisms of this impairment primarily because of the complex nature of task-switching and difficulty in probing the occurrence of worries within participants. To address this issue, we employed a stochastic diffusion model analysis along with a novel thought-probe technique in task-switching paradigm. Across 152 participants, we found state anxiety was linked to higher switch costs in nondecision time but not drift rate parameter of diffusion model, which indicates that the locus of task-switching impairment in anxious individuals is pertinent to the efficiency …

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …

Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier

Dissertations

Alcohol abuse is the third largest risk factor for disease world, responsible for an estimated 3.3 million deaths each year. The concomitant ingestion of alcohol and caffeine is hypothesized to increase risk factors associated with alcohol use alone by reducing subjective effects of intoxication. The zebrafish (Danio rerio) has recently garnered attention from researchers as an effective pre-clinical in-vivo animal model in behavioral pharmacology research, largely due to small size, low-cost and ease of drug delivery. A number of studies have reported the effects of alcohol and caffeine on zebrafish behavior at a variety of doses. However, the …

Bisphenol-A Exposure During Adolescence Leads To Enduring Alterations In Cognition And Dendritic Spine Density In Adult Male And Female Rats, Rachel E. Bowman, Victoria N. Luine, Samantha Diaz Weinstein, Hameda Khandaker, Sarah Dewolf, Maya Frankfurt

Psychology Faculty Publications

We have previously demonstrated that adolescent exposure of rats to bisphenol-A (BPA), an environmental endocrine disrupter, increases anxiety, impairs spatial memory, and decreases dendritic spine density in the CA1 region of the hippocampus (CA1) and medial prefrontal cortex (mPFC) when measured in adolescence in both sexes. The present study examined whether the behavioral and morphological alterations following BPA exposure during adolescent development are maintained into adulthood. Male and female, adolescent rats received BPA, 40 μg/kg/bodyweight, or control treatments for one week. In adulthood, subjects were tested for anxiety and locomotor activity, spatial memory, non-spatial visual memory, and sucrose preference. Additionally, …

Co-Worry In Friendship Dyads, Michelle H. Goldstein

Honors Scholar Theses

Anxiety disorders increase in prevalence from childhood into adulthood. Although cognitive theories are prominent in the etiology and maintenance of anxiety, peer relationships are emerging as salient interpersonal risk factors. This study investigates the effects of specific interpersonal interchanges on anxiety symptoms in college students. 60 undergraduates attended the experiment with a same-sex best friend, and were randomly assigned to the co-worry or neutral conversation condition. Each person completed self-report measures of state anxiety, negative affect and positive affect prior to and following an 8-minute conversation about self-generated worry topics such as exams or neutral topics such as the weather. …

One hundred thirty-five individuals completed an initial survey, with sixty five of the original group completing a follow-up survey five weeks later. Results indicated that anxious attachment was associated with a greater reported usage of social networking sites, whereas avoidant attachment predicted less instant message use over time. Depression symptoms and avoidant attachment were generally associated with perceptions of higher negativity and lower positivity with …

A Pilot Study To Explore The Use Of Expressive Writing To Reduce Anxiety And Psychological Threat In An Academic Setting, Cynthia Delores Jenkins

Counseling & Human Services Theses & Dissertations

The purpose of this study was to investigate if the use of Pennebaker's short-term expressive writing intervention would have a positive effect on the academic performance of a group of third semester underperforming freshmen. This is a relatively brief and simple intervention pioneered by J. W. Pennebaker (1997) who conducted numerous studies using the procedure. Most of the research has involved having subjects write about traumatic, stressful or emotional events for 15–20 minutes (the maximum) over 3–5 days. In contrast, the studies by Wilson (2006) and Cohen et al (2006) used self-affirmations for writing. For this study self-affirmation directions were …
