Semantic Network Activation Contributes To The Relationship Between Mood And Inhibition, James S. Maniscalco

Dissertations, Theses, and Capstone Projects

Prior research has identified several relationships between mood and executive functions. Very broadly, these findings generally suggest that positive moods are associated with enhanced cognitive performance, particularly in working memory and learning. However, recent studies note that there are some instances in which negative moods may benefit select executive skills, such as those involved in divided attention and inhibition. In sum, these findings indicate that positive moods favor top-down, heuristic, or relational processing, whereas negative trait moods favor bottom-up, detail-oriented processing. However, a clear mechanism by which these effects occur has yet to be identified.

Childhood Adhd, Impulsivity, And Alcohol-Related Impairment Among Diverse College Students, Mariely Hernandez

Dissertations, Theses, and Capstone Projects

Aims: We examined (1) if students with high childhood ADHD symptoms, and at high risk for alcohol use disorder (AUD) reported greater alcohol-related impairment (ARI) than their low childhood ADHD peers who had comparable rates of alcohol use; and (2) whether alcohol-related problems were more severe for those with high childhood ADHD and high AUD risk when their trait impulsivity was high.

Method: 18-to 25-year-old (N=81), racially/ethnically diverse, college students completed a two-part study. An online survey assessed childhood ADHD symptoms (Wender Utah Rating Scale) and past-year alcohol use (Alcohol Use Disorders Identification Test). Laboratory assessment comprised neuropsychological and self-report …

Barriers And Bridges To Intimacy: A Constellation Of Same-Sex Female Couples’ Experiences, Struggles And Strengths, Jenna K. Bennett

Dissertations, Theses, and Capstone Projects

Intimacy is central to romantic relationships, however, this aspect of experience has been largely unstudied in female couples. Further, few studies have looked at how minority stress and internalized homophobia impact these women’s experiences of intimacy. With a sample of 19 women, through self-report measures and a semi-structured interview, experiences of intimacy, the factors that impact intimacy, barriers to intimacy, and how couples bridge these barriers were explored. Quantitative analysis revealed an association between internalized homophobia and relationship satisfaction. Qualitative thematic analysis indicated that this group of women had a robust range of explicit and implicit experiences of intimacy. Further, …

The Relationship Of Pathological Narcissism To Empathic Functioning, Antonia M. Mcmaster

Dissertations, Theses, and Capstone Projects

This study examined the relationship of pathological (grandiose and vulnerable) expressions of narcissism to empathic functioning by comparing performance-based and self-report assessments of empathy. Current research suggests that narcissism is related to more impairments in affective than cognitive empathy, and that narcissistic individuals over-report their empathic capabilities overall on self-report measures because empathy is a socially-desirable trait, and they may wish to appear more empathic in order to manage the positive impression of others. Hierarchical regression analyses were conducted in an undergraduate college sample of eighty-nine participants using a cross-sectional study design. It was hypothesized that self-reported pathological (grandiose and …

A Comparison Of Simulated Schizophrenia In Mental Health Experts And Genuine Schizophrenia In Psychiatric Patients, Amanda Rosinski

Dissertations, Theses, and Capstone Projects

Malingering includes the intentional feigning of psychiatric symptoms combined with motivation for external gain (American Psychiatric Association, 2013). Malingering is likely to occur in the justice system in both criminal and civil contexts, as there is increased opportunity for secondary gain in these settings. When individuals successfully malinger, it can be very costly for the United States. For example, if an individual successfully malingers, it can delay their criminal proceedings, allow them to inappropriately use resources associated with psychiatric or medical treatment, allow them to gain access to unneeded medications or financial assistance, or allow them to avoid work (Chafetz …

Telehealth Caregiver Training: Treating Food Selectivity Without Extinction, Christina M. Alaimo

Dissertations, Theses, and Capstone Projects

Telehealth behavioral interventions are becoming increasingly necessary given limited accessibility for in-person services; while there is a growing evidence-base for these interventions, there are few applications for pediatric feeding disorders. Those studies that have evaluated telehealth feeding interventions have done so only after children received some form of in-person services. The purpose of this study was to evaluate a telehealth caregiver training package to teach caregivers to implement an alternative to escape extinction feeding intervention in their home to treat their child’s food selectivity. All three caregivers demonstrated high levels of correct performance following training and all children demonstrated increases …

The Influence Of Evidence-Based Sex Discrimination Policies On Women’S Perceptions Of Organizational Climate, Sexism, And Identity Safety, Maya A. Godbole

Dissertations, Theses, and Capstone Projects

Sexism has proven to be a stubborn barrier to women’s participation and advancement in workplaces and academic institutions (Rosette, Akinola, & Ma, 2017). Importantly, sexism in organizational settings has endured despite the implementation of federal, state, and organizational policies that prohibit discriminatory behavior. One reason for this may be that because organizational policies are typically written for the purpose of complying to federal and state laws, they do little to foster psychological safety among employees and address the “chilly” organizational climates that enable sexism. To that end, the current research aimed to (a) develop novel, evidence-based sex discrimination policies and …

The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas

Dissertations, Theses, and Capstone Projects

Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …

Youth Bystander Intentions To Intervene In Peer Intimate Partner Violence: The Co-Influence Of Perceived Perpetrator Race And Perceived Culpability, Nana Amoh

Dissertations, Theses, and Capstone Projects

In recent years, bystander intervention programs that focus on addressing violence have notably become more popular and prevalent on college campuses. Bystander intervention programs serve to help college students identify and intervene in emergency situations like intimate partner violence. Despite advances in the bystander intervention literature, there is a dearth of research that has examined bystander intentions to intervene in situations of intimate partner violence among youth who have witnessed violence between peers. This study examined bystander intentions to intervene among young adults who witnessed peer male-to-female physical intimate partner violence and whether intentions to intervene varied depending on perpetrator …

An Interdisciplinary Investigation Of Infant Sleep: How We Study It, What It Means For Other Areas Of Development, And Where Methodological Creativity Can Take Us, Melissa Noel Horger

Dissertations, Theses, and Capstone Projects

The present dissertation is broken into six chapters. Chapters 2 through 5 comprise four research projects that build upon each other and in both theoretical and methodological ways. The bookends – my introduction and conclusion – are written for an interdisciplinary, even lay audience. In its entirety, the text is centered on infant sleep. First, I describe the functional role of sleep and liken it to a barista working in a coffee shop. Then, I lay out researcher choices – of design and measurement – when incorporating sleep as a facet of a research paradigm. After comparing three measurement techniques …

Improving The Assessment Of Practical Judgment Ability In Older Adults, Crystal G. Quinn

Dissertations, Theses, and Capstone Projects

Judgment is an important aspect of executive functioning and critical to many aspects of real-world behavior. As the older adult population and incidence of dementia rises, the assessment of judgment during neuropsychological evaluations is important for informing diagnosis, understanding functional and cognitive competence, and designing effective treatment plans. The Test of Practical Judgment (TOP-J) is an objective verbal measure with two versions (i.e., 9 items and 15 items) that is increasingly used by neuropsychologists; however, initial validation research was conducted with a small, highly-educated non-Hispanic White sample. As a result, normative data and content may not be appropriate for individuals …

A Schema-Theoretic Approach To Hierarchy In Eighteenth-Century Tonality, Simon K. S. Prosser

Dissertations, Theses, and Capstone Projects

Prevalent modern-day theories of tonal hierarchy for eighteenth-century music, especially those influenced by the ideas of Heinrich Schenker, have been called into question by schema theorists such as Robert Gjerdingen and Vasili Byros, who argue from both cognitive and historical evidence that eighteenth-century tonal cognition was sequential or “windowed” rather than hierarchical. This dissertation seeks to recuperate the concept of tonal hierarchy in eighteenth-century music, drawing on research that reconstructs the implicit tonal theories of the partimento and thoroughbass traditions, as well as concepts of hierarchy from schema theory itself, to formulate a historically and cognitively grounded theory of tonal …

Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana

Dissertations, Theses, and Capstone Projects

Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …

Treatment, Diagnostic, Demographic, And Historical Factors Affecting Mental Health Diversion Outcomes, Amanda L. Reed

Dissertations, Theses, and Capstone Projects

The deinstitutionalization movement, which began in the 1950s and culminated in the closure of most psychological institutions by the 1980s, promised to usher in a new era of community mental health (Torrey et al., 2010). While the movement, which began largely due to advances in psychological treatment and the exposure of widespread abuses in asylums, was well-intentioned, it ultimately created new problems for people experiencing mental illness. Many of the programs designed to handle the influx of newly-released patients were never fully funded or well-received (Human Rights Watch, 2003). The criminal justice landscape also changed dramatically around the same time, …

The Psychological Allure Of Alford: Why Innocents Plead Guilty, Johanna Hellgren

Dissertations, Theses, and Capstone Projects

The Alford plea allows defendants to maintain their innocence while accepting a plea. Although this plea is more prevalent than jury trials, it is largely unknown to both lay people and researchers (Redlich & Özdoğru, 2009). Legal scholars have argued that the Alford plea may present an undue influence on innocent defendants who may not otherwise accept a plea, while other assert that the Alford plea is a beneficial alternative for defendants who want to preserve their reputation (Ronis, 2009; Ward, 2004). However, no research to date has explored either of these assumptions.

The goals of the current research were …

Contributions Of Reward Identity And Time Prediction Errors To Pavlovian Learning, Daniel B. Siegel

Dissertations, Theses, and Capstone Projects

Some models of associative learning attempt to explain effects such as blocking and unblocking as reflecting a prediction error (PE): Associative strength, and thereby learning, are said to be greater when the unconditioned stimulus (US) received following a cue deviates from one’s expectations. Some models of PE-motivated behavior and PE-relevant brain activity represent the US as a single quantitative variable for outcome value, and that learning therefore only occurs when outcome value differs from expectations. There is growing evidence to suggest that changes in other dimensions of reward, such as identity and timing, also contribute to learning. In Experiment 1, …

The Online Impossible Anagram Task: Development And Testing Of A Novel Online Cheating Paradigm, Emily Joseph

Dissertations, Theses, and Capstone Projects

For the past fifteen years, the Russano et al. (2005) cheating paradigm has dominated research in the forensic psychological literature. While this paradigm successfully activates theoretical mechanisms for ethical decision-making, applying the methods for online data collection is cumbersome and retains a confound inherent in the design. Alternative cheating paradigms from both the psychology and economics literatures were evaluated for their suitability for an online cheating paradigm. The impossible anagram task was selected as most likely to elicit the same internal and external cost-benefit analyses online as the Russano et al. (2005) cheating paradigm does in-person: self-concept maintenance, ethical dissonance, …

The Effects Of Constant And Descending Criterion-Level Frequencies On Skill Acquisition Outcomes, Anna Budd

Dissertations, Theses, and Capstone Projects

Higher levels of performance during skill acquisition predict higher levels of response maintenance, but less is known about how many observations of high levels of performance are needed to produce this effect of criterion levels. Across two experiments, we analyzed multiple criterion-level frequency values, or the number of observations of criterion-level performance during teaching. In Experiment 1, we taught children with disabilities target skills to 90% accuracy using constant criterion-level frequencies: one day versus three consecutive days. Across three participants and five comparisons, participants required fewer sessions to meet the terminal acquisition performance criterion when the frequency value was set …

Connect Or Protect: The Impact Of Ghosting On Potential Partner Perception And Pursuit, Maureen Coyle

Dissertations, Theses, and Capstone Projects

As an increasing number of individuals seek meaningful connections in online dating, it is important to understand how online dating users’ perceptions and behaviors vary because of contact being terminated with them without warning (i.e., being ghosted) and their regulatory focus. Research on how being ghosted affects users’ expectations and pursuit of potential partners is limited, despite ghosting being a pervasive online dating experience. Also, the role of users’ motivational systems of goal pursuit, namely regulatory focus (promotion focus: motive to affiliate/connect with others, prevention focus: motive to avoid rejection/protect the self), on users’ expectations and pursuit of potential partners …

The Federalist Papers' Account Of Human Nature, Jeffrey P. Smith

Dissertations, Theses, and Capstone Projects

This paper is an analysis of the account of human nature found in The Federalist Papers. This interpretation assumes The Federalist is a work of political rhetoric and advocacy, but also one of genuine significance as political science and philosophy. As a book, The Federalist is a coherent whole, which offers a coherent account of human nature, despite the collective nature of its authorship, the time pressures of its publication, and the piecemeal nature of its workmanship. This understanding of human nature is the thread which runs through all its analysis and numbers. Its arguments asserting the inadequacies of …

What We Owe To Our Audience: The Hermeneutical Responsibility Of Fiction Creators, Kathryn Wojtkiewicz

Dissertations, Theses, and Capstone Projects

The goal of this project is to provide a theoretical underpinning for the belief that creators of fiction should dedicate time to diversifying the cast of characters in their fictions, and to avoiding harmful stereotypes when doing so. I establish this as a hermeneutical responsibility: because of the epistemic influence fictions can wield over their audiences, trafficking in harmful stereotypes of marginalized identities (instances of which I call Bad Representation Problems) or excluding marginalized identities entirely (which I call No Representation Problems) from one’s fictions can reinforce harmful beliefs about real people with those identities. The more popular the fiction, …

The Effect Of Psilocybin On Personality, Ravital Labua

Dissertations, Theses, and Capstone Projects

As classic psychedelics are increasingly legalized and reintroduced into the psychotherapeutic frame, a deeper understanding of their effect on personality and overall wellbeing - as well as their clinical contraindications and potential pitfalls - will prove essential. As a result, this study represents a preliminary investigation into the effect of psilocybin exposure on a range of personality constructs.

Methods: Data was collected through a collaboration with The Psychedelic Society, an organization that legally administers psilocybin truffles in the Netherlands to self-selecting retreat attendees who have been screened for mental health disorders in accordance with Johnson et al.’s (2008) widely accepted …

A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab

Dissertations, Theses, and Capstone Projects

Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …

Motivation Of Networking Behavior: A Study Of Novel Interventions, Jeremy D. Rothstein

Dissertations, Theses, and Capstone Projects

Networking is a critical yet potentially underutilized career self-management strategy. The purpose of this dissertation was to explore the extent to which novel reading and writing exercises could foster networking motivation and network use. The first set, based on Social-Cognitive Career Theory (SCCT), was designed to increase participants’ confidence about their ability to engage in effective networking, and help them believe that networking is a valuable activity. The second set, based on Goal-Setting Theory (GST), was designed to help participants practice setting effective career development objectives and networking goals linked to those objectives. The Networking Information Control (NIC) condition was …

How Frustration Impacts The Relationship Between Potential For Child Physical Abuse Perpetration And Emotion Processing, Amanda L. Zwilling

Dissertations, Theses, and Capstone Projects

Research conducted over the past 20 years has substantiated the serious, long-lasting impacts of child physical abuse (CPA) has on individuals, families, and society. Research has also suggested several appreciable risk factors for perpetration of CPA. Intergenerational transmission of abuse, described as the personal experience of abuse or neglect during childhood, is prominent in the literature as a predictor of subsequent perpetration of CPA. However, the majority of individuals who experience abuse in childhood do not subsequently engage in perpetration of child abuse as adults. As such, the literature has sought to investigate risk factors that mediate the relationship between …

Learning To Feel Safe: A Translational Study Of The Influence Of Safety Learning On Anxiety-Related Overgeneralized Fear, Hyein Cho

Dissertations, Theses, and Capstone Projects

Anxiety disorders are among the most common mental health diagnoses, affecting about a third of the population in their lifetime. However, approximately a third of individuals with anxiety do not respond to current treatment approaches, highlighting the need to identify additional potential therapeutic mechanisms. Safety learning is one such mechanism, but methodological challenges and a dearth of research have prevented the field from advancing the understanding of the role of safety learning in the etiology and remediation of anxiety disorders. Animal research, using single-cued safety learning paradigms, has yielded promising early findings, demonstrating that safety learning directly reduces anxiety-related behaviors …

Early Emotion Regulation In The Children Of Superstorm Sandy, Jessica L. Buthmann

Dissertations, Theses, and Capstone Projects

Rising prevalence of childhood psychopathology mandate investigation into the antecedents of symptom onset. Growing evidence shows prenatal maternal stress experienced in utero is a strong contributor to offspring neurodevelopmental deficits, including emotion dysregulation, a core feature of many types of psychopathology. This dissertation summarizes a body of work studying children prenatally exposed to maternal stress related to a natural disaster, Superstorm Sandy (i.e., storm stress). This work includes six experiments conducted in the framework of the Developmental Origins of Health and Disease (DOHaD) hypothesis. The DOHaD hypothesis posits that developmental disruptions, like storm stress exposure, during a critical period of …

The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria

Dissertations, Theses, and Capstone Projects

Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …

Delayed Modulation Of Glutamate Receptors By Anti-Epileptic Drugs After Traumatic Brain Injury In Rats, Edgar Rodriguez

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a significant health concern. Around 74 million people sustain a traumatic brain injury worldwide. The damage caused by TBI produces two types of injury; primary and secondary injuries. Primary injury is caused within milliseconds and is irreversible. Secondary brain injury is delayed and produced by molecular, cellular, and structural disruption after the initial injury. One of the most devastating dysfunction after TBI is glutamate neurotransmitter overactivation that could lead to neurotoxic levels of glutamate in the brain (i.e., excitotoxicity). Excitotoxicity has been linked with the development of epilepsy after TBI, also known as post-traumatic epilepsy …

Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle

Dissertations, Theses, and Capstone Projects

Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …
