Exercise, Brain Plasticity, And Brain-Derived Neurotrophic Factors

Intuition: The BYU Undergraduate Journal of Psychology

Physical exercise influences neurobiological processes and cognitive abilities. For example, it increases the expression of brain-derived neurotrophic factor (BDNF), a protein responsible for maintaining synaptic connections as well as neuronal development, growth, and survival. The increase of BDNF promotes brain plasticity and has been shown to aid recovery from brain injuries, as well as to improve cognitive function in older adults. Recent studies with well-exercised rats showed strong, positive correlations between BDNF levels, cognitive performance in maze tasks, and recovery from fluid-percussion injuries to the hippocampus. Currently researchers are focusing on whether exercise prevents neurodegenerative diseases such as Alzheimer’s and …

A Comparison Of The Social-Adaptive Perspective And Functionalist Perspective On Guilt And Shame, Heidi L. Dempsey

Research, Publications & Creative Work

Within the field of guilt and shame two competing perspectives have been advanced. The first, the social-adaptive perspective, proposes that guilt is an inherently adaptive emotion and shame is an inherently maladaptive emotion. Thus, those interested in moral character development and psychopathology should work to increase an individual’s guilt-proneness and decrease an individual’s shame-proneness. The functionalist perspective, in contrast, argues that both guilt and shame can serve a person adaptively or maladaptively—depending on the situational appropriateness, duration, intensity, and so forth. This paper reviews the research conducted supporting both positions; critiques some issues with the most widely used guilt- and …

Attachment, Trauma, And Intimacy With God, Jodie Kathleen Gardner

Conversations: A Graduate Student Journal of the Humanities, Social Sciences, and Theology

Attachment theory provides a robust framework for understanding spiritual development and perceptions of God. An integration of research from attachment theory, affective neuroscience, emotional information processing, and trauma, is clarifying the competing research findings involving compensation and correspondence in spiritual development. Empirical evidence suggests the distinction between explicit theological beliefs and implicit perception of God as an attachment figure may explain the discrepancy between compensatory practices and correspondence, and how one interacts with God, and copes with negative life events. Studies of post-traumatic stress disorder suggest specific association between the extreme stress of trauma and alterations in emotional processing. Trauma …

Animal Hoarding By Humans: A Literature Review

Intuition: The BYU Undergraduate Journal of Psychology

I review the origin and treatment of animal-hoarding disorder in humans and its relation to hoarding disorder and obsessive-compulsive disorder, showing that it seems to be more closely related to object hoarding. The disorder often originates in a traumatic life event, which triggers a psychological vulnerability to compulsively collect animals. In some cases, the hoarding individual was neglected by parental figures at a young age and developed relationships with animals in order to cope with the neglect. Some theories that proposed to explain the neglectful behavior in animal hoarding include dissociation, delusion, and dementia, viewing the animals as self-objects, or …

Responding To Bullying By Gender

Intuition: The BYU Undergraduate Journal of Psychology

The present literature review examines how the construction of gender influences bullying among children and adolescents, as w ell as the possible effects of bullying on children, both as bullies an d victims. An in-depth, theoretical analysis of gender stereotype and gender construction is presented, through a review of cognitive development theory, social learning theory, and cultivation theory. Gender construction leads children to adopt different behaviors and to interact with peers in various ways (Emilson et al., 2016; Fagot, 1994; Tobin et al., 2010). Among children and adolescents, the two most prominent forms of bullying that result from gender construction …

The purpose of this study was to compare emotion and personality trait attributions to facial expression between American and Indian samples. Data were collected using Amazon.com’s Mechanical Turk (MTurk). Participants in this study were asked to correctly identify the emotion and make inferences from pictures of three different facial expressions (scowling, frowning, and smiling) of young white females and males in six photographs. Each picture was randomly presented for 10 seconds followed by four randomized questions about the individual in the picture. The first question asked participants to identify the emotion shown from a list of six emotions (anger, disgust, …

Examining The Perceived Influence Of A Comprehensive Youth Development Program For Promoting Black Male High School Persistence, Richard Gray Walker

Dissertations

Black male youth in the United States drop out of high school at a rate consistently higher than their White counterparts. A lack of academic persistence contributes to lower workforce participation rates among Black Americans, which leads to lower national productivity and unrealized personal prosperity. Youth development research has developed an extensive body of knowledge regarding possible causes and contributing factors of minority high school dropout. Literature shows youth experience higher dropout rates when they grow up in adversity. Adversity risks such as dysfunctional families, cultural discontinuity between home and school, dysfunctional neighborhoods, or low-expectations from teachers contribute to graduation …

Understanding Parents’ Attitudes Towards Complexity In Children's Books, Dorit Aram, Deborah Bergman Deitcher, Gali Adar

Reading Horizons: A Journal of Literacy and Language Arts

Experts in children's literature and child development value complexity in the language, socio-emotional content, and structure of books, yet little is known regarding parents’ attitudes towards these aspects. The study thus examined how parents’ gender, education, and profession, children's age and gender, and frequency of parent-child reading interactions predict parents’ support for complexity in children’s books. Participants were 104 parents to children aged 4-7. Parents completed questionnaires measuring frequency of shared book reading and levels of support for complexity of children’s narrative books in three areas: language, socio-emotional content, and structure. Results showed that parents supported complexity of socio-emotional content, …

An Assessment Of Frontal Lobe Activity And Bdnf Levels Following Concussion In Collegiate Athletes: A Near-Infrared Spectroscopy Study, Keara Kangas

All NMU Master's Theses

Impacts to the head that are associated with sports related injuries, can result in a mild traumatic brain injury (mTBI), known as a concussion. Previous research has assessed how mTBIs affect the brain, but these assessments are limited in their ability to directly measure the consequences of mTBI. Along with concussion assessments, only a few studies have used neuroimaging techniques to evaluate brain injury. This study utilized a neuroimaging technique that is inexpensive, non-invasive, and portable, to measure brain activity post-concussion. In particular, near-infrared spectroscopy (NIRS) was used to measure prefrontal cortex (PFC) activity during the dot-probe task of affective …

Acculturation And Language Use In Intimate And Sexual Relationships Among Chinese Bilinguals, Tianyi Xie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

People of Chinese heritage often face complex challenges because of the conflicting values from China and America, especially on sexuality. Through two thousand years of socialization, Chinese culture grew to endorse conservative sexual values and gender roles. In traditional Chinese culture, women are expected to remain chaste and play submissive roles in marriage. Sexuality is treated as a taboo topic that should not be discussed directly. Asian American youth who endorse less traditional Chinese values experience lower sexual satisfaction, lower confidence in their own abilities, and higher adherence to traditional gender roles. Language has also been found to potentially influence …

Electrophysiological Analysis Assessing The Analgesic Nature Of The Lateral Habenula (Lhb), Akshay Sunil Parchure

Psychology Theses - Archive

Local field potential (LFP) is a collective neural signal of all the synaptic activity occurring at a specific area of the brain, thereby offering a unique insight into how the brain functions. The habenula is involved in the pain pathway and decision-making. Located above the thalamus, it has been proposed to function with nucleus accumbens and periacqueductal gray (PAG) along with other regions in a descending pain modulation pathway. The main purpose of the present study was to determine the contribution of LHb to the nociceptive input and the effect of activation on antinociception. One week after implantation of electrode …

Trudy's Triumph: A Narrative Life History Of An Adolescent Survivor Of Abusive Head Trauma, Crystal G. Ledford

Doctoral Dissertations and Projects

The purpose of this narrative study was to describe the life history of an adolescent survivor of an abusive head trauma in the Southeastern United States. Abusive head trauma is a form of inflicted brain injury, often occurring because of violence in the form of shaking or impact to the head of an infant under the age of two years old (Chevignard & Lind, 2014). Life history is defined as a first-hand account to convey understanding of a life. The primary participant was a 19-year-old, Caucasian female survivor of an abusive head trauma that occurred when she was five months …

Preschoolers And Pandas Making Friends: A Journey About Healing From Brain Injury, Barbara Anne Doucette

Museum Studies Projects

Preschoolers that have obtained Non-Accidental Injury (NAI) from familial child abuse are in need of having a unique place for neurorehabilitation in correlation with traditional therapies. My thesis project suggests adding an exhibit annex to an existing giant panda exhibit that will give preschoolers an opportunity to help develop new neuropathways when exposed to mediation and creative activities. Meditation and creative activities are being examined by neuroscientists as an aid in neuroplasticity after brain injury. This thesis reviews the neurotypical preschooler’s milestones and the playful means by which they are achieved. Conjoining the contemporary museums’ and zoological gardens’ outreach to …

Life-Long Creativity: Changing The Narrative Of Aging And Retirement, Jennifer K. Gippel Dr

Creativity and Change Leadership Graduate Student Master's Projects

The current narratives and stereotypes around retirement and aging are both inaccurate and incomplete. The popular media regularly portrays retirees and older citizens as blissfully happy but bland; or physically feeble and forgetful. Rarely are they portrayed as achievers and vibrant problem solvers. Instead they are perceived by policy makers as a problem to be solved. This project offers a different narrative ― one that presents retirement and aging as a unique time of creative opportunity, possibility, and freedom to choose. The primary outcome of the project is two chapters of a book entitled: Retirement by design: How to discover …

Association Between Latent Toxoplasma Gondii Infection And Alzheimer's Disease, Cynthia Elizabeth Wyman

Theses and Dissertations

Introduction: Many studies have found an association between Toxoplasma gondii seropositivity and behavioral and cognitive changes in animal models and in humans. In addition, early findings have suggested an association between T. gondii seropositivity and Alzheimer's disease (AD). We sought to determine whether there is an association between T. gondii seropositivity and AD as well as cognitive functioning (including memory, working memory, processing speed, language functioning, executive functioning) in a large, well-characterized sample of subjects with AD and matched controls without dementia. Method: Using ELISA assays, we determined anti-T. gondii IgG antibody titers in 114 control subjects and in 105 …

Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway

Dissertations

Bottlenose dolphins are an important species of interest because they possess a variety of abilities that are relatively rare in the animal kingdom, one being complex acoustic communication. Signature whistles - distinctive calls that are unique for each individual – are one of the most studied call types, but we know little about how these calls are used in various contexts, such as during an introduction. Looking at the socio-behavioral context in which signature whistles are used is likely the best way of learning how these whistles are used in a particular context (Caldwell, Caldwell, & Tyack, 1990). For this …

Evaluating Social Network Dynamics Of Bigg’S Killer Whales (Orcinus Orca) And Vessel Traffic Within A Transboundary Region: Implications For Conservation Management, Courtney Smith

Dissertations

The social lives of animals are defined by group dynamics based on the nature and strength of associations and movements between individuals, often resulting in highly complex and interconnected social networks. However, understanding of how environmental variables may shape this structure is poorly understood. Within the inland waters of Washington State and southern Vancouver Island, British Columbia, mammal-eating Bigg’s (transient) killer whales occur in relatively small, but stable social groups. Group size and occurrence in recent years has increased, coinciding with a growing whale watching industry. Given the central importance of the social network within killer whale population dynamics, such …

Escorting Of Mother-Calf Pairs Of Humpback Whales (Megaptera Novaeangliae) In The Colombian Pacific During The Breeding Season, Natalia Botero Acosta

Dissertations

Humpback whales (Megaptera novaeangliae) belonging to the “breeding G-stock” annually migrate from the Antarctic Peninsula and southern Chile to the southeastern Pacific to reproduce. Associations between mother-calf pairs and escorts were examined in the Gulf of Tribugá, northern Colombian Pacific, using photo-identification and behavioral/spatial sampling. Research hypotheses included: 1. The association between cows and escorts is short-lived, consistent with a male reproductive strategy, 2. The presence of escort(s) elicits a behavioral response from mother-calf pairs and, 3. The patterns of spatial distribution reflect the spatial segregation of maternal females. Groups were classified as mother-calf pairs (Mc), mother, calf …

Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony

Electronic Theses, Projects, and Dissertations

Adolescence is a vulnerable developmental period in regards to drug initiation and use. The gateway hypothesis suggests that adolescent cigarette smoking may result in a heightened risk for methamphetamine use. However, little is understood about the role of nicotine on adolescent methamphetamine addiction. The aim of the present study was to determine whether early, late, or continuous adolescent nicotine exposure would alter oral methamphetamine self-administration, extinction, or reinstatement. A total of 164 male and female Sprague-Dawley rats were pretreated with saline or nicotine (0.16, or 0.64 mg/kg, sc) beginning on postnatal day (PD) 25 for 10 consecutive days. On PD …

Age Of Drinking Initiation’S Association With Cognitive Functioning, Joshua Seth Goldberg

Loma Linda University Electronic Theses, Dissertations & Projects

Research has indicated that alcohol abuse is associated with deleterious effects on cognitive functioning later in life, specifically in the neuropsychological domains of immediate memory, delayed memory, and attention. However, research has been mixed regarding how age of initiation into problem drinking affects cognitive health after abstinence. This study aimed to identify if earlier age of alcohol abuse was associated with significant deficits in neuropsychological functioning in comparison to individuals who commenced alcohol abuse later in life. Participants were recruited from an alcohol rehabilitation program within Loma Linda University’s Behavioral Medicine Center and were administered the Repeatable Battery for the …

Effects Of Environmental Enrichment On Self-Administration Of The Short-Acting Opioid Remifentanil In Male Rats, Rebecca S. Hofford, Jonathan J. Chow, Joshua S. Beckmann, Michael T. Bardo

Psychology Faculty Publications

Background

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil.

Methods

Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of …

Understanding Stress Reactivity In Schizophrenia, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The role of stress has long been recognized in schizophrenia; several theories have identified the role of stress as an important factor in the etiology of schizophrenia. A handful of studies have used laboratory psychosocial stressors to examine cortisol stress response in schizophrenia; the results obtained have consistently suggested that the stress response is attenuated in people with schizophrenia. Present study set out to examine stress responsivity in schizophrenia relative to healthy controls. A laboratory stress test was used to investigate cortisol response, heart rate and task appraisal in a sample of 17 healthy controls and 16 men diagnosed with …

Two-Week Test-Retest Reliability Of The Scale Of Accurate Personality Prediction, Lisa Dawn Stewart

Theses and Dissertations

The Scale of Accurate Personality Prediction (SAPP) is a measure derived from the Sixteen Personality Factor Questionnaire (16PF Fifth Edition) with the objective of assessing one’s level of self-knowledge. The SAPP measures self-knowledge by appraising the extent to which individuals are able to accurately predict their personality traits. Previous research on the SAPP has provided support for its construct validation. The present study served as a replication of prior reliability studies to further assess the SAPP’s temporal stability. Test-retest reliability data of the SAPP was obtained by comparing SAPP scores from 34 individuals across two testing sessions that were two …

Assessment Of Reliability And Stability Of Various Visual Search Parameters, Michael Don Mizer

Graduate Theses/Dissertations

Research in social science has been on a continuous self-correcting path as scientists find new ways to look at old problems. Recent technology has given us the ability to perform compounded calculations in a fraction of previous times while recording complex measurements with greater degrees of precision. While this is helpful regarding corporeal measures, quantifying cognition is still a difficult task. Recently, many computer-aided eye tracking devices have been developed and used to validate visual search theories. However, few inquiries have been made assessing the reliability and stability of these methods. This study assessed the reliability and stability of visual …

Moving Toward A Collective Impact Effort: The Volunteer Program Assessment, Sheridan Trent, Kelly Prange, Joseph A. Allen

Psychology Faculty Publications

Volunteers are essential to the operation of many nonprofits, but some experience challenges in retaining their volunteer workforce. The Volunteer Program Assessment (VPA) seeks to address this issue by helping organizations to identify strengths, growth areas, and recommendations for improving volunteer experiences. To maximize the effectiveness of VPA’s mission, the organization is moving toward a collective impact (CI) approach. Although not developed as a CI effort, the program currently exemplifies many of its characteristics, which have been instrumental in expanding reach to more organizations. We examine VPA’s alignment with collective impact and outline how VPA will continue to improve efforts.

The Mental Homologies Of Mammals. Towards An Understanding Of Another Mammalsworld View, Marthe Kiley-Worthington

Theory of Mind Collection

Mammals’ mental homologies include that they look after their young, suckle and protect them; they acquire information about the world by learning. They have five types of sensory receptors and a brain to analyze the information and they feel: that is they are sentient. Mental homologies have been largely ignored by behavioural scientists since Darwin because of certain historical beliefs. This however has not been the case for people who have had to do with non-human mammals who have long recognized their mental similarities to humans. As a result, behavioural science has sponsored some inappropriate research (examples are given). The …
