Voluntary Oral Methamphetamine Reveals Susceptibilities To Spatial Memory Deficits, Decreased Dopamine Marker Expression And Increased Neuroinflammation In The Hippocampus Of Male And Female Mice, Jorge A. Avila

Dissertations, Theses, and Capstone Projects

Methamphetamine is an addictive illicit psychostimulant that produces lasting neurochemical and behavioral changes. The mechanisms underlying these deficits have been characterized in animal models using extremely high doses. Currently, better translational models are needed to understand the onset and progression of these deficits that more accurately reflect the gradual and voluntary dosing parameters as chosen by an abuser. To that end, a new model of methamphetamine administration, labeled Voluntary Oral Methamphetamine Administration (VOMA), offers a means to examine the progression of neurotoxicity, behavioral deficits, and the addiction process through a voluntary consumption framework.

Female populations show consistent vulnerabilities to methamphetamine, …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

The Impact Of Racial Microaggressions And Major Discriminatory Events On Mental Health, Florence Lui

Dissertations, Theses, and Capstone Projects

The current study, a secondary data analysis, sought to determine the number and nature of latent groups for experiences of spectrum racial discrimination (i.e., both major and microaggressive racial discrimination) in a sample of emerging adults from a people of color (POC)-majority public university setting in the United States, and to understand the role of socio-demographic variables in defining each group. In addition, the study aimed to ascertain the extent to which endorsing spectrum racial discrimination experiences predicted anxiety and/or depression above the effects of general, non-race-related stress. Finally, the analyses gauged the mediating and/or moderating role of coping in …

Mental Health Professionals’ Attitudes Toward Clients With Antisocial Personality Disorder: An Exploratory Study, Edward T. Dunbar Jr., Shari M. Sias, Stephen Leierer, William L. Atherton, Robert J. Campbell, Lloyd R. Goodwin Jr

Journal of Counselor Preparation and Supervision

This exploratory study examined mental health professionals’ attitudes toward clients with antisocial personality disorder. Specifically, are mental health professionals’ attitudes influenced by (a) personal experiences with criminal victimization, or (b) contact with clients with antisocial personality disorder. A factorial MANOVA and follow-up univariate ANOVAs revealed a statistically significant main effect in relation to participants’ level of clinical contact with clients having antisocial personality disorder. Participants with higher levels of clinical contact were associated with more positive attitudes towards clients. Implications for mental health professionals, supervisors, and counselor educators are discussed, and suggestions for future research are provided.

The Double-Edged Sword Of Diagnosis: Medical Neoliberalism In Rape Crisis Center Counseling, Shannon M. Peters

Graduate Doctoral Dissertations

The prevalence of sexual violence in the United States is a critical issue and the aftermath of sexual assault can have profound effects on psychological well-being. Rape Crisis Centers play a vital role in supporting sexual violence survivors. The framework through which Rape Crisis Center clinicians understand the experiences of survivors has a substantial impact on the course of counseling, how survivors interpret their own experiences, and survivors’ psychological health. A neoliberal medicalized framework conceptualizes distress post-sexual assault as a disease or disorder and places the responsibility on an individual to ‘fix’ themselves, situating the problem within the person, rather …

Reviewing The Heroic Experience: A Humanistic And Existential Counselling Perspective, Peter Bray, Peter James

Heroism Science

Taking a humanistic and existential counselling stance, this brief review of heroism and the heroic experience begins by discussing the utility and structure of Joseph Campbell’s (1949) monomythic narrative of the hero’s journey, whilst considering the Jungian conceptualisation of the archetype and the collective unconscious. With their shared assumptions about transformation and growth, modern psychology and the therapeutic practice of counselling and psychotherapy are reviewed in terms of their utilisation of the hero-journey as a developmental metaphor for clients, particularly in trauma recovery. It is also suggested that, as a metaphor for transformation, Campbell’s hero-narrative may also have the potential …

Language Nutrition For Language Health In Children With Disorders: A Scoping Review, Janet Y. Bang, Aubrey S. Adiao, Virginia A. Marchman, Heidi M. Feldman

Faculty Research, Scholarly, and Creative Activity

The quantity and quality of child-directed speech—language nutrition—provided to typically-developing children is associated with language outcomes—language health. Limited information is available about child-directed speech to children at biological risk of language impairments. We conducted a scoping review on caregiver child-directed speech for children with three clinical conditions associated with language impairments—preterm birth, intellectual disability, and autism—addressing three questions: (1) How does child-directed speech to these children differ from speech to typically-developing children? (2) What are the associations between child-directed speech and child language outcomes? (3) How convincing are intervention studies that aim to improve child-directed speech and thereby facilitate children’s …

Exploration Of The Interaction Of Maternal Experience Of Trauma And Infant Temperament On Maternal Parenting, Julie Christine Van Weelden

College of Science and Health Theses and Dissertations

Among women over age 18, 1 in 3 have experienced intimate partner violence, including physical aggression and stalking, and nearly 1 in 5 have experienced some type of sexual violence during childhood, adolescence, or adulthood (Black et al., 2011). Given the high rates of trauma experiences in women of childbearing age, especially in low-income populations (Gillepsie et al, 2009), it is critical to examine the effect these experiences have on women´s parenting, especially during infancy, a sensitive period for many important domains of child development (Bornstein, 2002). Previous research has demonstrated experiencing victimization can affect maternal caregiving (Trickett, Noll, Putnam, …

Functional And Anatomical Variations In Retinorecipient Brain Areas In Arvicanthis Niloticus And Rattus Norvegicus: Implications For The Circadian And Masking Systems, Dorela D. Shuboni-Mulligan, Breyanna L. Cavanaugh, Anne Tonson, Erik M. Shapiro, Andrew J. Gall

Faculty Publications

Daily rhythms in light exposure influence the expression of behavior by entraining circadian rhythms and through its acute effects on behavior (i.e., masking). Importantly, these effects of light are dependent on the temporal niche of the organism; for diurnal organisms, light increases activity, whereas for nocturnal organisms, the opposite is true. Here we examined the functional and morphological differences between diurnal and nocturnal rodents in retinorecipient brain regions using Nile grass rats (Arvicanthis niloticus) and Sprague-Dawley (SD) rats (Rattus norvegicus), respectively. We established the presence of circadian rhythmicity in cFOS activation in retinorecipient brain regions in …

Addressing Racial Disparities In Parent Training Enrollment: An Examination Of Help-Seeking For Child Behavior Problems Among African American Mothers, Kasia Plessy

LSU Doctoral Dissertations

The consideration of African American mothers’ mental health help-seeking attitudes and intentionsis important when developing culturally sensitive parent training programs and potentially help bridge a critical knowledge and service gap for this population. The purpose of this study is to examine the parental help-seeking for child externalizing behavior problems in order to delineate variables that might influence BPT enrollment among African American families. To address the lack of research considering cultural factors, this study examines the influence of racial group identification, cultural childrearing values, and mental health stigmatization on African American mothers’ problem recognition and willingness to engage in behavioral …

Workplace Incivility Against Women In Stem: Insights And Best Practices, Mahima Saxena, Timothy Adam Geiselman, Sheng Zhang

Psychology Faculty Publications

As demonstrated by both empirical and non-empirical research, women are more likely than men to be a target of workplace incivility. This manifests in a variety of negative outcomes for female employees, including turnover intentions, poor performance, and higher levels of stress. The problem is exacerbated for women in STEM fields due to factors unique to these industries. Herein, we outline the unique characteristics of STEM organizations that can foster the creation and sustenance of an atmosphere promoting workplace incivility against female employees. Then, we provide five best practice recommendations geared toward reducing incivility, improving work climate, and promoting overall …

Mindfulness And Blood Pressure Across Demographics: Analyses From The Serenity Study, Gabrielle R. Chin

Theses and Dissertations

Mindfulness, as a state, trait, and training, is linked with myriad positive mental and physical health outcomes. Understanding the individual characteristics potentially influencing links between mindful traits, mindfulness training, and physical health, is therefore important, yet remains under-addressed. Utilizing data from the ongoing Serenity Study (NCT02371317), the current project examines if (1) at baseline, higher trait mindfulness relates to lower BP consistently as a function of demographics, (2) Mindfulness-Based Stress Reduction (MBSR) training lowers BP consistently across demographic subgroups and initial levels of trait mindfulness, and (3) if change in trait mindfulness following MBSR training correlates with change in BP …

The Relationship Between Undergraduate Research Training Programs And Motivational Resources For Underrepresented Minority Students In Stem: Program Participation, Self-Efficacy, A Sense Of Belonging, And Academic Performance, Jennifer Lindwall

Dissertations and Theses

Although calls for a more diverse workforce in biomedical fields have been widespread, racial and ethnic gaps in biomedical degree attainment persist. In order to succeed, URM STEM students must persevere despite numerous challenges and stay continuously motivated on the long road to degree attainment in biomedical disciplines. Past higher education research has identified two key self-appraisals, a sense of belonging and self-efficacy, as crucial for student success. These beliefs, which can serve as motivational resources for students, include students' convictions about whether they are a valued member of their academic community and whether they have what it takes to …

Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth

Arts & Sciences Graduate Student Theses and Dissertations

Recent research has suggested an association between motivational impairment in those with schizophrenia and reduced willingness to expend effort on experimental tasks. However, few studies have examined the neural correlates of effort-based decision-making in those with schizophrenia. In the current study, we aimed to examine willingness to expend effort, the associated neural circuitry of effort-based decision-making, and the impact of experimentally-defined effort-based decision-making on daily motivational experience in schizophrenia. We recruited 28 individuals with schizophrenia and 30 healthy controls to perform an effort-based decision-making task while undergoing fMRI scanning. In order to assess whether willingness to expend effort was associated …

Spatial Navigation Ability As A Predictor Of Increased Clinical Impairment, Taylor Hendershott

Arts & Sciences Graduate Student Theses and Dissertations

Spatial navigation deficits are observed in Alzheimer disease (AD) cross-sectionally, but prediction of longitudinal clinical decline has been less examined. Cognitive mapping (CM) was assessed in 95 participants and route Learning (RL) was assessed in 65 participants at baseline. Clinical progression over an average of 4.16 years was assessed using the Clinical Dementia Rating scale. Relative predictive ability of these tasks was compared to episodic memory, hippocampal volume and cerebrospinal fluid (CSF) biomarkers (ptau₁₈₁/Aβ₄₂ ratio). CM and RL were significant predictors of clinical progression (ps181/Aβ₄₂ in prediction (psTaken together the results suggest that baseline spatial navigation …

Using The Coaching Approach Behavior And Leading By Modeling (Calm) Program To Examine Attachment And Parental Behaviors In Childhood Anxiety, Seana Bandi

Electronic Theses and Dissertations

Anxiety is one of the most common disorders in children that can often lead to detrimental outcomes. Empirically-supported risk factors for child anxiety include the child’s temperament and behavioral inhibition, insecure attachment, parental over-controlling behaviors, parental anxiety, and the impact of adverse life events on the child. Targeting these risk factors early on has the ability to lead to a decrease in anxiety symptoms later in adolescence and adulthood.

Evidence suggests behavioral, therapeutic interventions are effective for treating anxiety and other mood disorders for middle childhood and adolescents. Recent research has begun to focus on developmentally-appropriate adaptations for younger children …

School-Based Services For Children With Pediatric Acute-Onset Neuropsychiatric Syndrome (Pans), Maura Miglioretti

Electronic Theses and Dissertations

Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) is an emerging disorder affecting school age children causing deleterious cognitive, social, emotional, and academic effects. Most frequently, children with PANS demonstrate severe, rapid-onset obsessive-compulsive symptoms in addition to a variety of other psychiatric disturbances. Symptoms are known to significantly a child’s educational experience. Despite this, little is known about the educational impacts related to the disorder or the supports provided to children with the diagnosis. This research sought to identify the school related impairments of children with PANS, the school-based services provided for children with PANS, and the relationships between obsessive compulsive symptoms and …

School Based Policies Protecting Lgbtq+ Youth, Amy Tiberi

Electronic Theses and Dissertations

According to the 2017 National School Climate Survey, over half of all LGBTQ+ students reported experiencing LGBTQ+ related discriminatory policies or practices in their schools (GLSEN, 2019). While there is legislation in place that should standardize compliance and equality within school districts, there is often a discrepancy in implementation and follow through in public school systems. This study sought to examine a) school psychologists’ knowledge of federal legislations protecting LGBTQ+ youth, b) school psychologists’ self-report of the implementation of these regulations in their school’s policies, and c) the attitudes of school psychologists working with LGBTQ+ youth. Results indicated that attitude …

Impact Baseline Composite Score Differences Among Student Athletes, Kerry Schutte

Electronic Theses and Dissertations

The ImPACT aims to measure neurocognitive functioning in student athletes. Many schools administer preseason ImPACT assessments to determine athletes’ baseline functioning. Follow-up ImPACT assessments are administered to athletes who sustain concussions to compare their pre- and post-injury functioning. Normative data may be used in place of individualized baseline scores if athletes were not administered baseline assessments. At the inception of this study, normative datasets consisted of scores from typically developing athletes. However, research suggests athletes of varying gender and exceptionality statuses perform differently on baseline ImPACT assessments. In particular, differences were found among male and female athletes as well as …

Kink In Flux: Bdsm Theory And Sexual Praxis, Celeste Pietrusza

Electronic Theses and Dissertations

The opening decades of the 21^st century have seen a veritable explosion of representations of bondage, discipline and sadomasochism (BDSM) and kink practices in mainstream media and American culture. Along with this, empirical researchers working in sexuality studies continue to show, contrary to the history of stigmatizing accounts in the history of clinical psychology, no evidence of increased pathology and, in some studies, better outcomes on measures of mental health.

Given the legacy of psychoanalysis in foregrounding considerations of sadomasochism and sexuality for the human psyche, it seems particularly well positioned to approach the complexities of dynamic fantasies involved …

Reclaiming Embodiment: An Existential-Phenomenological Exploration Of Women’S Tattoos, Ashley Gill

Electronic Theses and Dissertations

This dissertation is a phenomenological research study about the lived experiences of women who elected to get tattoos in the last five years. Due to historical and present discourses on female embodiment and persistent stigmas and pathologies often associated with tattoos, I sought to generate meaningful knowledge about the lived experiences of women who have voluntarily chosen this form of body modification. I conducted phenomenological research interviews with nine participants about personal meanings, decision making processes, and lived experiences of embodiment (capturing existential themes of lived body, spatiality, relationality, and time) before and after tattooing. I applied thematic interpretation of …

Adult And Juvenile Rats Differentially Express Mpfc Glua2 Following Traumatic Memory Retrieval, Edgar Rodriguez

Theses and Dissertations

To advance our understanding of how traumatic memories are modulated between adults and juveniles, we characterize the AMPAr subunits, GluA1, GluA2, GluA3 in the mPFC of rodents following traumatic memory retrieval.

GluA2 was differentially expressed in adults but not juveniles rats. There were no changes in GluA1 or GluA3 expression

Judging Facial Expressions Of Emotion: Effects Of Gender, Raine Palladino

Theses and Dissertations

This study examined how quickly people recognize happy, neutral or angry emotional expressions on faces that varied in gender presentation and femininity/masculinity of facial features. Facial features influenced judgments of emotion more for women than men. Neutral expressions were more likely seen as angry on a woman’s face.

The Effect Of Dopamine Blockade On Sensorimotor Gating In Social Phenotypes Of The African Cichlid Fish Astatotilapia Burtoni, Raymond A. Turco

Theses and Dissertations

We asked if blocking dopamine could improve implicit sensory gating deficits in a socially-defeated fish of a naturally-agonistic species. This study investigated the effects of dopamine D2R receptor antagonist metoclopramide on sensorimotor gating using a prepulse inhibition (PPI) paradigm in social phenotypes of male A. burtoni African cichlid fish.

Weak Social Support As An Indicator For Worse Trauma Related Symptoms, Michael B. Sugarman

Theses and Dissertations

This study investigated the relationship between social support and trauma related symptoms in trauma exposed participants. Using the SCID and CAPS, weak family support factors were found to be associated with a greater number and severity of trauma related symptoms; suggesting that family support is important for trauma exposed people.

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

The Path To God Is Through The Heart: Metaphoric Self-Location As A Predictor Of Religiosity, Adam K. Fetterman, Jacob Juhl, Brian P. Meier, Andrew Abeyta, Clay Routledge, Michael D. Robinson

Psychology Faculty Publications

Metaphors linking the heart to warm intuition and the head to cold rationality may capture important differences between people because some locate the self in the heart and others locate the self in the head. Five studies (total N = 2575) link these individual differences to religious beliefs. Study 1 found that religious beliefs were stronger among heart-locators than head-locators. Studies 2 and 3 replicated this relationship in more diverse samples. Studies 4 and 5 focused on questions of mediation. Heart-locators believed in God to a greater extent partly because of empathy-related processes (Study 4) and partly because they tended …
