The Relationship Between Amygdala And Orbitofrontal Cortex Volume In The Context Of Oppositional Defiant Disorder, Rahul Alla

Honors Scholar Theses

Disobedient and rebellious attitude in children is on the rise and this type of behavior is categorized as Oppositional Defiant Disorder (ODD). ODD in children can be identified as a persistent pattern of angry or irritable mood, argumentative or defiant behavior or vindictiveness toward others according to the Diagnostic and Statistical Manual (DSM-5, Fifth Edition) of Mental Disorders.1 Children with ODD typically have difficulty regulating and processing their emotions. Issues with regulating emotions is defined as the process by which individuals “influence which emotions they have, when they have them, and how they experience and express them”.2 Dysregulation of emotions …

Stress-Induced Oxytocin Reactivity As A Predictor Of Daily Support Seeking After Stress, Cecile Sunahara

Psychology Theses and Dissertations

The current study examined whether stress-induced peripheral oxytocin (OT) was associated with support-seeking behaviors after stress in daily life. Healthy male and female participants (N=94) performed a standardized laboratory stressor, the Trier Social Stress Test (TSST), and then completed two weeks of daily assessments of support seeking after stress. In line with preregistered hypotheses, plasma OT reactivity to the TSST (indexed as the area under the curve with respect to increase; AUCi) was associated with more frequent support seeking behaviors following stress in daily life. Moreover, this association was stronger for individuals with higher levels of attachment anxiety, relative to …

Examining The Effects Of Acute And Chronic Stress On The Interrogative Suggestibility Of Young Adults, Claudia Cota

Open Access Theses & Dissertations

High-stress situations, like police interrogations, can hinder an individual's decision-making and critical-thinking ability (Liston et al., 2009), making them more susceptible to suggestive or leading messages during questioning. While research on suggestibility mainly focuses on children and adolescents, young adults may also be vulnerable to suggestion because of their sensitivity to social feedback (Blakemore & Mills, 2014; Redlich & Goodman, 2003). Since the legal consequences of suggestibility for young adults are more severe than for children or adolescents, it is essential to examine the role of stress in young adults' suggestibility. The present study used objective and subjective methods to …

Examining The Effects Of Menstrual Cycle Phase And Hormonal Contraceptive Use On Women's Sleep, Charles Ethan Coombs

Psychological Science Undergraduate Honors Theses

Women overrepresent men for sub-optimal sleep, a consequence of hormone fluctuation in the menstrual cycle affecting sleep regulatory pathways. While research has examined the prevalence of sub-optimal sleep through cycle phases, little research has examined how hormonal contraceptives (HC’s) could similarly affect women’s sleep, while also neglecting to utilize subjective sleep measures. In this study, we examine subjective sleep quality among naturally cycling (NC) women, women using different HC types, and between active and inactive phase pill users by subjecting 463 women to a subjective sleep battery. We hypothesized that HC users would report more sub-optimal sleep than NC women. …

Mate Guarding Against Strong Men Displaying Affiliative And Aggressive Humor, Jacob Pauley

Biological Sciences Undergraduate Honors Theses

Mate retention behaviors serve to discourage partner defection from a current pairbond. Such behaviors are oftentimes more prevalent toward intrasexual rivals exhibiting physical and behavioral cues implicating that rival as an optimal mate. Among these features in men are their upper body strength, a feature diagnostic of heritable fitness, and men's ability to produce humor, a cue to their social competence. This study considered the intersection of these desirable features in shaping men's mate retention behavior toward an intrasexual rival. After learning of a hypothetical interloper exhibiting high or low upper body strength while similarly using humor in an affiliative …

Exploring Auditory Thalamocortical Pathways In Autism Spectrum Disorder, Caitlin Dyer

LSU New Orleans Theses and Dissertations

Thalamocortical tracts related to language have rarely been examined in autism spectrum disorder (ASD). We examined the medial geniculate nucleus (MGN), Heschl’s gyrus (HG), and planum temporale (PT) volumes, and the connections from MGN to HG and MGN to PT, using MRIs from 39 children with ASD (20 with receptive language impairment, 19 without) and 20 typically developing controls, aged 5-17 years. In children with ASD without language impairment, MGN volume was positively correlated with receptive language scores. Additionally, the thalamus was smaller in children with ASD with language impairment, correlating negatively with receptive language scores in this group. Left …

Neurocorrelates Of Character Choice In A Videogame Task, Elijah Nieman

All NMU Master's Theses

An individual’s experience of autonomy or lack thereof has a significant effect on interest and motivation towards everyday activities. The present study looks to expand on basic research by examining the neurocorrelates of interest following supporting and thwarting of autonomy through character choice in a videogame task. Previous research has demonstrated an important role of digital avatars on perceived autonomy and interest, and early neurological results have shown that choice of visual frame affects reward processing of task outcomes. Together, autonomy supports seem to enhance engagement and interest in a situation. In the present work, participants were presented with five …

Impact Of Perinatal Escitalopram Exposure On Adolescent Behavior, Jessica Bezenah - Bottorff

Electronic Theses, Projects, and Dissertations

Escitalopram (EST), a selective serotonin reuptake inhibitor (SSRI), is an antidepressant frequently used during pregnancy, yet there is limited knowledge of its long-term effects on maternal use. Past studies suggest that maternal exposure may adversely affect the fetus, which may be due to the hyperserotonergic environment caused by the nature of SSRIs during early development. Modifications of the serotonergic system in offspring during certain critical periods of development may result in long-term behavioral and cognitive changes in adulthood. Further, recent human studies have demonstrated that prenatal exposure to SSRIs in humans may increase susceptibility to autism spectrum disorder (ASD) and …

Exposure To The Trier Social Stress Test Enhances Central Detail Memory, Reduces False Memory, And Results In Intrusive Memories That Last For Days, Mercedes L. Stanek, Kayla Boaz, Taylor D. Niese, Kristen E. Long, Matthew S. Risner, John G. Blasco, Koen N. Suzelis, Kelsey M. Siereveld, Boyd R. Rorabaugh, Phillip R. Zoladz

ONU Student Research Colloquium

Recent work has used a modified version of the well-known laboratory stressor, the Trier Social Stress Test (TSST), to study participant memory for a stressful experience. The paradigm is useful because, unlike most studies examining stress effects on memory, it allows investigators to measure what participants remember about the stressor, not unrelated information. It also presents an opportunity to model other stress-related symptoms, such as intrusive memories, but these have yet to be assessed with this paradigm. Intrusive memories have been notoriously difficult to measure in laboratory settings; most of this research involves participants watching arousing videos and subsequently reporting …

Addicted To The Beloved? A Comparison Of Craving For And Attention To Beloved And Vape Stimuli, Caitlyn Harriman

Theses

People who are in love seem to be addicted to their beloved. People who are in love have attentional biases for the beloved and people who are addicted have attentional biases for the substance they are using. This raises the question of how similar craving and attention are for the beloved and an addictive substance. However, there are no studies that directly compared craving and attention to the beloved and addictive stimuli. The aims of the current research were to directly compare subjective emotional experiences, sustained motivated attention, and early automatic attention for the beloved and vape stimuli, in people …

The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Gender, Graduate School Stage, And The Impostor Phenomenon, John-Scott B. Kelley, Angela T. Barlow

Journal of Graduate Education Research

The impostor phenomenon (IP) includes five central factors: (a) a sense of fraudulence or phoniness; (b) a fear of failure and discovery; (c) compensatory perfectionism (i.e., procrastination and/or over-preparation); (d) interpersonal anxiety; and (e) externalized success and/or discounted positive feedback. After the final stage, the process starts over with reinforced vigor, creating a self-reinforcing cycle in which success is associated with psychological suffering. IP was initially used to describe the reports of high-achieving women, but recent studies have shown that IP is experienced across genders. Additionally, while graduate school is an achievement-oriented environment with many characteristics that could promote IP, …

Neurobiology And Treatment Of Relationships, Harvey Joanning

University Faculty and Staff Publications

This paper presents a neurobiological theory of how intimate human relationships develop over the life span. It begins with an exploration of affective neuroscience, the study of emotions, and applies these concepts to the stages of relationship development. It goes on to explore the role of neurobiology in parenting, family life, divorce, and death of a spouse. Therapeutic interventions appropriate to each stage of relationship development are also explored. Every attempt is made to make this theory scientifically sound by basing the concepts described on published scientific research. “Hard science” has been differentiated from “clinical lore.” The reader is invited …

The Relationship Between Cognitive Impairment In Psychiatric Patients And Readmission Rate To An Inpatient Facility, Cherilyn Isis Schuff

Theses and Dissertations

The primary intention of this study was to further understand the impact of assessing cognitive impairment in psychiatric patients, as a mediating factor on readmission rates. Mild cognitive dysfunction impacts a patient’s functional outcomes (Bowie & Harvey, 2006; Davis et al., 2012; Marcantonio, et al., 2001). Little information exists to guide best practices in the treatment of adults with cognitive impairment who are hospitalized for acute conditions (Davis et al., 2012). A cognitive impairment may impact patient prognosis and ability to function outside of a setting focused on stabilization. Neuropsychological testing is a valuable tool in predicting a patient’s cognitive …

Shamika Ellis, Theresa A. Moore, Hannah B. White, PhD

This presentation will review the literature on the epigenetics of abused foster children, and the subsequent acute, delayed, and long-term physiological, cognitive, and behavioral effects. One study experimentally investigated the effects of sexual and physical abuse on 150 foster children from 8 to 19 years of age and found post-traumatic stress disorder (PTSD) was diagnosed in 64% of children who experienced sexual abuse and 42% of children who experienced physical abuse Further, of the foster children who had not experienced either form …

Proteomic Profiles Of Cytokines And Chemokines In Moderate To Severe Depression: Implications For Comorbidities And Biomarker Discovery, Kathleen T. Watson, Jennifer Keller, Caleb M. Spiro, Isaac B. Satz, Samantha V. Goncalves, Heather Pankow, Idit Kosti, Benoit Lehallier, Adolfo Sequeira, William E. Bunney, Natalie L. Rasgon, Alan F. Schatzberg

Psychology Division Scholarship

Objective: This study assessed the proteomic profiles of cytokines and chemokines in individuals with moderate to severe depression, with or without comorbid medical disorders, compared to healthy controls. Two proteomic multiplex platforms were employed for this purpose. Metods: An immunofluorescent multiplex platform and an aptamer-based method were used to evaluate 32 protein analytes from 153 individuals with moderate to severe major depressive disorder (MDD) and healthy controls (HCs). The study focused on determining the level of agreement between the two platforms and evaluating the ability of individual analytes and principal components (PCs) to differentiate between the MDD and HC groups. …

The Power Of Polish: Exploring The Impact Of Nail Adornments On Perceptions Of Attraction, Sara Demichele

Honors Theses

Understanding the significance of nail adornments in shaping perceptions of attractiveness and mate value provides insights into human behavior and preferences. In the current investigation, participants rated human nail length and color on physical attractiveness and partner desirability measures. Results revealed significant effects of nail length and color across different demographic groups. Medium-length nails consistently received higher ratings for physical attractiveness, cuteness, and partner desirability compared to short and long nails. White-colored nails were generally rated most attractive, while blue and black nails received the lowest ratings. Additionally, participants reported a moderate association between having manicured nails and feelings of …

Sympathetic-Cardiovascular Stress Reactivity In Adults With Major Depressive Disorder, Ashley Darling

Kinesiology Dissertations - Archive

Major depressive disorder (MDD) is a mood disorder characterized by persistently depressed mood and/or anhedonia that causes significant functional impairment in daily life. MDD affects nearly 15% of adults in their lifetime, and since 2019, prevalence estimates have increased up to ~30% in young adults (18-25 years old). In addition to its debilitating effects on daily functioning, epidemiological studies link MDD to ~3 times greater risk of cardiovascular disease (CVD), followed by accelerated CVD progression and mortality. Although the mechanisms contributing to MDD-CVD comorbidity are unclear, there is evidence of stress system dysfunction in adults with MDD.

Accordingly, the aim …

The Effects Of Early Developmental Co-Exposure To Alcohol And Nicotine Via E-Cigarettes On Anxiety- And Motor-Related Behaviors In Mice, Carley Cirafesi

West Chester University Master’s Theses

Thirty percent of people who report consumption of alcohol while pregnant simultaneously report consuming nicotine. Prenatal co-exposure to alcohol and nicotine has increased with the popularity of electronic cigarettes due to their presumed safety, yet e-cigarette use may have a greater impact on fetal development than traditional cigarettes. Prenatal exposure to alcohol or nicotine is associated with increased anxiety-related behaviors and impaired motor coordination later in life, yet it is unknown whether prenatal co-exposure to alcohol and nicotine exacerbates these effects, particularly via e-cigarettes. This project examined the effects of co-exposure to alcohol and nicotine via e-cigarettes during early development …

Cognitive Functioning In Well-Controlled Asthma, Erin Walsh

West Chester University Doctoral Projects

Asthma is a common lung disease that impacts lung functioning through inflammatory based mechanisms. Past research suggests that decreased blood oxygenation due to asthma attacks may impair cognitive capabilities (Irani et al., 2017). Moreover, the observed differences in cognition between those with and without asthma may be associated with disease severity or asthma control respectively in asthma populations. The current study explored differences in cognitive functioning between college students with and without self-reported asthma. Sociodemographic data, self-reported asthma severity, and measures of asthma control were collected. The current study did not find significant differences in measures of cognitive efficiency between …

The Behavioral Origins Of Phylogenic Responses And Ontogenic Habits, W. David Stahlman, Kenneth J. Leising

Psychological Science Articles

An examination of innate behavior and its possible origins suggests parallels with the formation of habitual behavior. Inflexible but adaptive responses-innate reflexive behavior, Pavlovian conditioned responses, and operant habits-may have evolved from variable behavior in phylogeny and ontogeny. This form of "plasticity-first" scientific narrative was unpopular post-Darwin but has recently gained credibility in evolutionary biology. The present article seeks to identify originating events and contingencies contributing to such inflexible but adaptive behavior at both phylogenic and ontogenic levels of selection. In ontogeny, the development of inflexible performance (i.e., habit) from variable operant behavior is reminiscent of the genetic accommodation of …

Electrophysiological And Clinical Fundamentals Of Qtc Prolongation Induced By Antipsychotic Medications, Zaid Naseer, Minaal Khan, Najeeb Manalai, Allison Foroobar, Patricia Harrison, Charles Scercy, Beth Yanoff, Partam Manalai

Department Surgery Faculty Publications

Patients with psychiatric disorders undergoing antipsychotic treatment are at an elevated risk for adverse cardiovascular events, including arrhythmias and sudden cardiac death. While the precise mechanisms linking cardiovascular diseases and psychiatric conditions remain unclear, QTc prolongation is suspected to be a contributing factor. The human ether-à-go-go-related gene (hERG, or KCNH2), which affects potassium channels, is implicated in the cardiotoxicity of various medications, including antipsychotics. This gene plays a critical role in determining whether a drug will be approved for market use. This paper elucidates the electrophysiological basis of QTc prolongation and reviews the evidence concerning which antipsychotics may exacerbate QTc …

Simulated Effects Of Postpartum Depression On Maternal-Infant Bonding: Mediated By Reward-Related Responses To Infant Facial Cuteness, Caitlin Harp

Cal Poly Humboldt theses and projects

Infant cuteness (facial cuteness in particular) is linked to evolutionary adaptations to motivate caretaking and protective behaviors (Kringelbach et al., 2008). Previous neuroimaging work has demonstrated that infant cuteness activates reward-related regions in the brain (Glocker et al., 2009) and behavioral work suggests that the reward value of cuteness is linked to maternal tendencies (Hahn et al., 2015). It is estimated that 15% of new mothers experience postpartum depression (PPD) (Wisner et al., 2013), which impacts the mesolimbic system and is linked to anhedonia (i.e., reduced ability to experience pleasure). Based on the above literature, this study used a simulated …

A Comparison Of Symptom Profiles In Probands With 16p11.2 Deletion And Duplication Syndromes: Repetitive Behavior And Psychosis Proneness, Adrianna Rakauskas

Honors Theses

The present study examines two classes of behavior in probands with the 16p11.2 duplication and deletion: repetitive behavior and psychosis spectrum behavior. It was hypothesized that 1.) deletion and duplication cases will differ significantly in the means and profiles of repetitive behaviors across five subscales and 2.)16p11.2 duplication cases will exhibit more schizotypal traits than the deletion cases. Data on 94 total participants was obtained from the Simmons Variation Individuals Project. Three scales were used to measure behavior: the Childhood Routines Inventory-Revised, the Childhood Oxford-Liverpool Inventory of Feelings and Experiences, and the Child Behavior Checklist. Data analysis was conducted using …

Emotional Throwing: Decision Making And Emotion In The Dual-Process Theory, Eve Wasil

Honors Program Theses

The dual process theory of decision-making describes system 1 as automatic and system 2 as controlled (Frankish & Evans, 2009). While much research has been conducted on system 2 and emotional arousal, little is known about how arousal affects the more automatic, gut-feeling processes of system 1. Through galvanic skin response (GSR), a system 1 ball throwing task, and a system 2 trolley problem survey, this study measured emotional arousal’s effect on both systems in conjunction with one another. Results revealed minimal effects of emotion on system 1 and system 2, leaving room for speculation as to the robustness of …

Understanding The Application Of Evolutionary Psychology In Consumer Behavior: A Review And Future Research Agenda, Faegheh Taheran, Veronica L. Thomas, Kendra Fowler, Abdolati Mortazavi

Marketing Faculty Publications

This paper is the first to offer a comprehensive literature review of the role of evolutionary psychology (EP) in marketing and consumer behavior. This study takes a holistic approach, combining techniques of a systematic review with bibliometric analysis, to provide a performance analysis and identify theories and methodologies used in the literature. Most importantly, by studying the current state of EP, we elucidate six major themes: the role of gender in families, the role of affect in consumer behavior, food preferences and shopping behavior, motivations for and consequences of status signaling, the impact of ovulation on consumer motives and behaviors, …

Synthetic Neuroactive Steroids Targeting Gaba-A Receptors As A Potential Therapy For Contraceptive-Associated Mood Disorders, Alexandria A. Davis

Scripps Senior Theses

4-10% of women who use hormonal oral contraceptives (HOCs) discontinue use after experiencing symptoms of anxiety, irritability, and depression in the first 3 months of administration. Previous studies have acknowledged a relationship between HOCs and emotional dysregulation but have not identified mechanisms by which HOCs have this effect. As a result, effective treatment options for HOC-induced mood disorders are lacking. Current theories implicate combined-HOCs, particularly those containing ethinyl estradiol and levonorgestrel (EE-LNG), in reducing neuroactive steroid levels. Specifically, HOC users show decreases in allopregnanolone, a positive allosteric modulator associated with neuronal inhibition and emotional regulation. The objective of this study …

Differences In The Neurological Functioning Of Females And Males During The Human Sexual Response Cycle: A Quantitative Systematic Review, Zachary Larson

Theses and Dissertations

The psychology field recognizes differences between females and males. Yet, there is a lack of research examining neurobiological sex differences, and a sophisticated understanding of neurobiological contributors that explain these sex differences related to sexuality is lacking. An integrative systematic review of the literature examined differences in the neurological functioning between females and males during the human sexual response cycle (SRC). This study investigated sex differences and commonalities in regional neural activation during the four stages of the human SRC (i.e., excitement, plateau, orgasm, and resolution). The main result of this study is that the differences between females and males …

Opioid System's Potential Involvement In Ketamine's Cognitive And Antidepressant-Like Effects In Rats, Fan Zhang

Theses and Dissertations

Depression stands as one of the most pervasive mental health challenges worldwide, including the United States. Conventional antidepressants typically display a delayed onset of therapeutic action (4-8 weeks) and lack efficacy in a substantial portion of patients (over 40% of depressed patients are treatment-resistant). The dissociative anesthetic ketamine, which is a glutamatergic N-methyl-D-aspartate (NMDA) antagonist, has emerged as a promising novel treatment due to its rapid and prolonged antidepressant effects, and it is especially beneficial for treatment-resistant depression. Nevertheless, the precise neurochemical mechanisms underlying ketamine’s antidepressant properties remain elusive, hampering the development of safer and more efficacious treatments. The present …
