The Human Instinct To Resilience: Clinical And Evolutionary Efficacy Of Intrinsically Motivated Stressor Exposure, Brady Barley

Ramifications

Environmental stressors threaten optimal behavioral functioning, and thus contribute to the development of psychopathology and exert evolutionary selection pressure. Voluntary stressor exposure has the efficacious effect of increasing resilience to future stressors in humans and other animals. This theoretical paper considers the hypothesis that intrinsic motivation toward behaviors requiring voluntary stressor exposure mitigates evolutionary selection pressure exerted by environmental stressors by inducing neural and neuroendocrine plasticity which results in increased resilience. In this view, intrinsically motivated stressor exposure is both efficacious and innate. Empirical and theoretical support for this hypothesis suggest that humans possess an instinct to resilience. Stress-related disorders …

Antecedents Of Borderline Personality Disorder And Antisocial Personality Disorder: An Examination Of Gene X Environment Interactions, Amy L. Medina

Dissertations, Theses, and Capstone Projects

Current thinking suggests that genotypes associated with impulse-control disorders and negative emotionality, such as monoamine oxidase-a (MAOA), interact with negative early environmental factors like childhood maltreatment and develop into the disorders know as Borderline Personality Disorder (BPD) and Antisocial Personality Disorder (ASPD). Using existing data from a prospective cohort design study of the consequences of child abuse and neglect, participants (N = 896 represent individuals with documented histories of child abuse and neglect and a matched comparison group that were followed up into adulthood and interviewed. A subsample of 631 participants gave permission for DNA extraction and analyses during …

Fundamental Principles Of Metacognition: A Qualitative Study Of Metacognition, Pedagogy And Transformation, Philip Hulbig

Educational Studies Dissertations

This study investigated the transformative quality of a metacognitive education. It examined a transformative metacognitive education from both the subjective personal perspective of the student who has gone through the process of transformation and the more objective pedagogical perspective of the professors who work to bring forth such transformational experiences in their students. Through interview and analysis these perspectives were integrated to produce a pedagogical theoretical framework derived from experience and grounded in observations about metacognition across various scientific disciplines. The personal elements of metacognition that promote educational transformation from within the students were contrasted with the pedagogical approaches of …

Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad

Jeffrey Stevens Papers & Publications

Teaching owners how to train their dogs is an important part of maintaining the health and safety of dogs and people. Yet we do not know what behavioral characteristics of dogs and their owners are relevant to dog training or if owner cognitive abilities play a role in training success. The aim of this study is to determine which characteristics of both dogs and owners predict success in completing the American Kennel Club Canine Good Citizen training program. Before the first session of a dog training course, owners completed surveys evaluating the behavior and cognition of their dog and themselves. …

Are Capuchin Monkeys (Sapajus Spp.) Sensitive To Lost Opportunities? The Role Of Opportunity Costs In Intertemporal Choice, Elsa Addessi, Valeria Tierno, Valentina Focaroli, Federica Rossi, Serena Gastaldi, Francesca De Petrillo, Fabio Paglieri, Jeffrey R. Stevens

Jeffrey Stevens Papers & Publications

Principles of economics predict that the costs associated with obtaining rewards can influence choice. When individuals face choices between a smaller, immediate option and a larger, later option, they often experience opportunity costs associated with waiting for delayed rewards because they must forego the opportunity to make other choices. We evaluated how reducing opportunity costs affects delay tolerance in capuchin monkeys. After choosing the larger option, in the High cost condition, subjects had to wait for the delay to expire, whereas in the Low cost different and Low cost same conditions, they could perform a new choice during the delay. …

Effects Of Human-Animal Interactions On Affect And Cognition, Elise L. Thayer, Jeffrey R. Stevens

Jeffrey Stevens Papers & Publications

Human-animal interaction has clear positive effects on people’s affect and stress. But less is known about how animal interactions influence cognition. We draw parallels between animal interactions and exposure to natural environments, a research area that shows clear improvements in cognitive performance. The aim of this study is to investigate whether interacting with animals similarly enhances cognitive performance, specifically executive functioning. To test this, we conducted two experiments in which we had participants self-report their affect and complete a series of cognitive tasks (long-term memory, attentional control, and working memory) before and after either a brief interaction with a dog …

Caution Fatigue: Group Identification And Disgust Provide Protection In The Covid-19 Pandemic, Logan F. Ashworth

Cal Poly Humboldt theses and projects

The current Coronavirus pandemic has yielded an abundance of concerns regarding the psychological effects of isolating a highly social species through widespread lockdowns and enhanced social distancing. Research show that many are suffering from mental health crises, while also refusing to isolate (Brooks et al., 2020; Czeiler, et al., 2020). These behaviors combine to increase risk of viral infection. An emerging term to explain this paradox is “Caution Fatigue”. Yet, there is no research that outlines its specific underlying mechanisms. The goal of this paper is to propose a series of models that delineate caution fatigue through the effects a) …

Bold Signal Variability Patterns In Neural Correlates Of Reflection And Brooding Components Of Rumination, Katie Leutzinger, Carissa Philippi

Undergraduate Research Symposium

Researchers have established that rumination is a debilitating symptom that positively correlates with symptoms of depression. Rumination involves self-focused attention, often negative, as a means of coping with a depressed mood or sadness. The Ruminative Responses Scale (RRS) is a tool used to measure rumination severity that includes two subsets of rumination: brooding and reflection. Brooding rumination is related to passive and judgmental thoughts about one’s circumstances and is therefore associated with higher levels of past and current depression. Although brooding is thought to be a maladaptive response to feelings of depression, past studies suggest that the reflection subtype may …

Developmental Influences On The Initial Subjective Rewarding Effects Of Etoh, Madison Waldron

Master’s Theses

The present studies were aimed to better understand developmental contributions to the risk for disordered drinking, and facilitate the long-term goal of developing effective interventions for individuals at high risk for alcohol use disorders. Experiment 1 assessed the effect of adolescent pre-exposure to ethanol on adult place preference, as well as, sex- and beta-endorphin(bE)-related contributions. Adolescent C57BL/6J and bE deficient mice were injected with 1.5g/kg of ethanol or saline and put back into their home cages. At the time of adulthood, we employed a single-exposure conditioned place preference paradigm (SE-CPP) to investigate the impact of preexposure on the initial subjective …

Analysis Of Circadian Rhythm Irregularities On The Health Of Shift Workers, Sahil Rajan

Williams Honors College, Honors Research Projects

Circadian rhythms involve the natural 24 wake-sleep cycle that governs proper maintenance of biological sleep schedules. Circadian rhythm disruption has been associated with health issues such as diabetes, obesity, and mental health disorders such as bipolar and sleep disorders. In this study, a survey method was utilized in order to analyze specific population demographics to determine whether working day or night shifts predisposed individuals to health issues due to disruptions in their circadian rhythms. This study was also carried out to observe popular coping strategies among night shift workers. Of all the variables tested comparing the difference between day and …

Music And Its Effects On The Brain, Caitlyn Herron

Williams Honors College, Honors Research Projects

This paper will discuss, in short, how music influences our brain, as well as some behavioral and physiological effects as a result. The brain consists of many regions responsible for different cognitive processes, such as learning, memory, recall, speech, and our emotions. It has been found that music helps to facilitate all of these cognitive processes, regardless of its emotional valence or whether the music is active or passive, such as singing or listening to it, respectively. It was discovered that music influences our ability to learn novel concepts related to mathematics, reading, and even language acquisition. It was also …

Pharmacokinetics And Reward-Related Behaviors Of Ethanol In Male And Female Japanese Quail (Coturnix Japonica), Shannon Eaton

Theses and Dissertations--Psychology

Ethanol is one of the most widely used and abused drugs. Problem use is associated with many different health problems and the economic burden is in the billions of dollars. Additionally, many people have difficulty controlling their ethanol consumption and about 5% of adults end up with an alcohol use disorder (AUD). Many people with an AUD often find themselves in a cycle of binge, remission, and relapse.

Following ethanol consumption ethanol enters the bloodstream from the small intestine where it gets distributed to peripheral tissues. Ethanol in the bloodstream is cleared from the system by the liver. The primary …

The Interactive Effects Of Brain-Derived Neurotrophic Factor (Bdnf) Polymorphisms And Posttraumatic Stress Disorder On Neurocognitive Functioning In U.S. Military Veterans, Colton Shafer Rippey

Theses and Dissertations--Psychology

Posttraumatic Stress Disorder (PTSD) is associated with mild-to-moderate deficits in neurocognitive functioning. Single nucleotide polymorphisms (SNPs) in the brain-derived neurotrophic factor (BDNF) gene, namely, the Met allele, may also be associated with mild deficits in neurocognitive functioning. However, findings are inconsistent and may be sensitive to environmental epigenetic moderators such as psychopathology.

The current study analyzed data from European-American U.S. military veterans (n = 1,244) who participated in the 2011 National Health and Resilience in Veterans Study (NHRVS). Multivariate analyses of covariances were conducted to evaluate the unique and interactive effects of the Met allele and probable PTSD on …

Identifying Neuron Clusters Controlling Movement Vigor, Jay A. Strabinick

Cal Poly Humboldt theses and projects

Parkinson’s disease (PD) is a neurodegenerative disease that progressively decreases dopaminergic function. Lower amounts of dopamine may cause an innate motivational shift that decreases movement vigor when performing difficult tasks. In PD patients, bradykinesia, the slowing of movement, is characteristic of this decrease in vigor. The movement vigor hypothesis proposes that dopamine neurons modulate performance aspects of movement, like speed and persistence. This paper proposes a series experiments utilizing neuron recording techniques in zebrafish that would test the movement vigor hypothesis by determining whether in fact there is a distinct group of dopamine neurons that modulate movement vigor. Core elements …

Social Comparison Tendencies And The Reward Value Of Same-Sex Beauty Among Heterosexual Women, Melissa M. Martin Ms.

Cal Poly Humboldt theses and projects

Previous studies have suggested that heterosexual women, but not heterosexual men, find same sex beauty rewarding. This finding has been attributed to a “greater bisexual interest among heterosexual women”, but no other explanations have been offered or tested. The current study aimed to explore social comparison tendencies as a potential alternate explanation to this previously observed finding. Twenty-three heterosexual women completed a series of questionnaires designed to assess their social comparison tendencies (the social comparison orientation scale, the physical appearance comparison scale, and the intrasexual competition scale). They also completed a “pay-per-view” keypress task to measure the reward value of …

Stress, Resilience, And Impulsivity, Kendra Clark, Adam Runyan, Carissa Philippi

Undergraduate Research Symposium

Stress is a phenomenon that everyone will experience. Stress that is unmanageable can become chronic, which is linked to various negative psychological effects (Le Fevre, Matheny, & Kolt, 2003). Although stress research often focuses on the negative long-term effects, there are times where individuals develop a trait known as resilience. Resilient individuals eventually learn how to buffer the negative effects of stress (Cicchetti, 2010), and researchers have begun investigating the positive effects of resilience on stress (Cicchetti, 2010; Kermott, Johnson, Sood, R., Jenkins, & Sood, A., 2019). Currently, few studies have been conducted to identify any additional traits that may …

Relationships Between Adverse Childhood Experiences, Inflammation And Pain In Youth And Emerging Adults With Sickle Cell Disease, Angela Pascale

Theses and Dissertations

Sickle cell disease (SCD) is a prevalent genetic disorder involving red blood cells. SCD is a multisystem disease and is connected to various severe medical complications, including debilitating pain. Though pain and inflammation have been connected to adverse childhood experiences (ACEs) in other populations, no prior work has investigated ACEs within a SCD population. The current study examined the prevalence of ACEs as well as the association of ACEs, inflammation, and pain in a sample of youth and young adults with SCD. Utilizing the biopsychosocial model of pain, I examined individual and cumulative ACEs as possible factors relating to inflammation, …

Do You Copy? Post-Traumatic Stress Disorder, Auditory Processing, And Heart Rate Variability, Lyndsey Johnson

UNF Graduate Theses and Dissertations

Self -report measures used in PTSD research have the potential to limit the degree of symptom severity in military veterans, especially as there is often underreporting in this population (Kline, Falca-Dodson, Susner et al., 2010). Polyvagal Theory provides a framework assessing if physiological measures can tap into PTSD Symptomology (Porges, 1995). It is therefore hypothesized that lower scores on auditory processing tests will be positively correlated with higher scores on Stress and PTSD measures. Additionally, it is thought that lower scores on auditory processing tedts as well as higher scores on PTSD and Stress Measures will be positively correlated with …

A Conceptual Proposal For The Epigenetically Causal Relationship Between Parental Ptsd And Inflammatory Disease In Post Hoc Offspring., Emma Griffith

Williams Honors College, Honors Research Projects

Could a combat veteran's horrific experiences in early-2000s Afghanistan have a direct, biological impact his now-adult daughter's risk of a heart attack later in her life? This concept would have been unapologetically mocked a mere twenty years ago, and it has only been in the past decade that the new field of epigenetics has revealed a distinct possibility for this event to actually take place—for parents' experiences to profoundly influence the biology of their children. The major objective of this research project is to argue for the legitimacy of this theoretical phenomenon by discussing the latest data regarding PTSD's interaction …

The Inevitability Of Collision: Creating Empathy Through Fiction, Danielle Beckman

Regis University Student Publications (comprehensive collection)

While the stigma for mental illnesses has greatly declined in the last decade, there is still a disconnect between individuals without neurological illnesses and those with neurological illnesses, especially those that cause individuals to lose contact with reality. The goal of this interdisciplinary paper is to create empathy for these individuals, specifically people with schizophrenia, Alzheimer disease, and post-traumatic amnesia. Through a collection of four stories told from the perspective of these unreliable narrators, I used fiction writing techniques from the field of cognitive literary studies such as gapping and defamiliarization to create more empathy in the reader. In reading …
