Do Continuum Beliefs Reduce Schizophrenia Stigma? Effects Of A Laboratory Intervention On Behavioral And Self-Reported Stigma, Ryan Thibodeau, Lindsay N. Shanks, Brian P. Smith

Psychology Faculty/Staff Publications

Background and objectives

Correlational research shows that belief in a continuum of psychiatric problems predicts decreased public stigma. However, the correlational findings fail to inform the stigma reduction prospects of manipulating continuum beliefs. All extant experimental work has been executed online. This study examined effects of a laboratory-based continuum intervention on behavioral and self-report measures of psychiatric stigma.

Methods

Sixty-nine undergraduates believed that they would meet a man with schizophrenia. They then read a bogus scientific article that attested to a categorical view of schizophrenia, a continuum view, or that merely described schizophrenia. Some participants then completed a task that …

Evidence Of Youthful Aging: Chronic Stress And The Association With Dna Damage, Jason M. Fly, M. Catherine Desoto

McNair Scholars Program Summer Research Symposium

Abstract: Persistent elevated basal levels of the hormone cortisol are an indication of chronic stress. Maladaptive response to stress, or chronic psychological stress, is thought to play a crucial role in the biological mechanisms involved in mental disorders, disease, and accelerated aging. In 2011, a critical connection was reported between elevated cortisol and the oxidative damage to DNA associated with aging and disease in a study of elderly participants (ages 63-83) via 24-hour urinary samples (Joergensen, et. al., 2011). This connection, if verified, has implications for how stress may accelerate the aging process and the onset of cancer, diabetes, and …

Neuroplasticity Pathways And Protein-Interaction Networks Are Modulated By Vortioxetine In Rodents, Jessica A. Waller, Sara Holm Nygaard, Yan Li, Kristian Gaarn Jardin, Joseph A. Tamm, Aicha Abdourahman, Betina Elfving, Alan Pehrson, Connie Sánchez, Rasmus Wernersson

Department of Psychology Faculty Scholarship and Creative Works

Background: The identification of biomarkers that predict susceptibility to major depressive disorder and treatment response to antidepressants is a major challenge. Vortioxetine is a novel multimodal antidepressant that possesses pro-cognitive properties and differentiates from other conventional antidepressants on various cognitive and plasticity measures. The aim of the present study was to identify biological systems rather than single biomarkers that may underlie vortioxetine's treatment effects. Results: We show that the biological systems regulated by vortioxetine are overlapping between mouse and rat in response to distinct treatment regimens and in different brain regions. Furthermore, analysis of complexes of physically-interacting proteins reveal that …

Materialist And Causal Bridges Over The Explanatory Gap, Celine Geday

Anthós

The explanatory gap about the subjective nature of conscious experience is the gap in explanation between conscious experience, and available scientific explanations of conscious experience. The explanatory gap is, as Joseph Levine states, the problem that physicalism (or the physical sciences) has in describing mental terms and experiences.7 Thomas Nagel also describes the explanatory gap problem as the problem of explaining the subjective in objective terms. He states that the subjective viewpoint of the individual is inherently at odds with an objective, or physical explanation.8 Describing someone’s experience of the redness of red, for example, by describing the neural mechanisms …

Impact Of Stress, Fear And Anxiety On The Nociceptive Responses Of Larval Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Lynne U. Sneddon

Sentience Collection

Both adult and larval zebrafish have been demonstrated to show behavioural responses to noxious stimulation but also to potentially stress- and fear or anxiety- eliciting situations. The pain or nociceptive response can be altered and modulated by these situations in adult fish through a mechanism called stress-induced analgesia. However, this phenomenon has not been described in larval fish yet. Therefore, this study explores the behavioural changes in larval zebrafish after noxious stimulation and exposure to challenges that can trigger a stress, fear or anxiety reaction. Five-day post fertilization zebrafish were exposed to either a stressor (air emersion), a predatory fear …

Comparing Social Science And Computer Science Workflow Processes For Studying Group Interactions, Joseph A. Allen, Colin Fisher, Mohamed Chetouani, Ming Ming Chiu, Hatice Gunes, Marc Mehu, Hayley Hung

Psychology Faculty Publications

In this article, a team of authors from the Geeks and Groupies workshop, in Leiden, the Netherlands, compare prototypical approaches to studying group interaction in social science and computer science disciplines, which we call workflows. To help social and computer science scholars understand and manage these differences, we organize workflow into three major stages: research design, data collection, and analysis. For each stage, we offer a brief overview on how scholars from each discipline work. We then compare those approaches and identify potential synergies and challenges. We conclude our article by discussing potential directions for more integrated and mutually beneficial …

Designing An Authentic Behavioral Research Experience In The Classroom Using Siamese Fighting Fish, Betta Splendens, Gianne Souza, Ronald M. Coleman

STAR Program Research Presentations

Recently there have been major shifts in biology education towards emphasizing the teaching of the scientific process to more closely reflect actual scientific practices. Authentic research experiences require the development of many higher order cognitive skills. Creating an authentic research experience that appropriately scaffolds the development of these complex skills while engaging individual student motivation remains challenging in classroom settings. Some common challenges include limited time available for working with large numbers of students, cramped working areas, and limited funding and materials resources. Using the Siamese Fighting Fish, Betta splendens, we have created an economically viable authentic animal behavioral …

The Role Of Personality Using The Millon College Counseling Inventory In Explaining A Variety Of Career Decision-Making Variables, Carly Chadick

Dissertations

In vocational research, the Five Factor Model (FFM) is one of the most popular theories of personality used when evaluating the role of personality in career development. However, thus far, few other personality theories have been used in vocational research, such as Millon’s theory. Therefore, the purpose of this study was to examine how Millon’s theory, operationalized using the Millon College Counseling Inventory (MCCI), may explain career development constructs, above the FFM traits, in a college student sample. Results indicated that the MCCI explained additional variance beyond FFM traits in several different career variables (i.e., profile elevation, negative career thinking, …

Evaluating The Use Of Self-Relevant Stimuli In Attention Bias Modification Training As A Treatment For Anxiety: A Near-Infrared Spectroscopy Study, Jacob Scott Aday

All NMU Master's Theses

Increased attentional bias to threat has been identified as a causal mechanism in the development of anxiety. As such, attention bias modification (ABM) was conceived as a treatment option where anxiety is alleviated through a computerized cognitive training regimen that reduces an individual’s attentional bias to threat. However, few studies to date have examined how to tailor ABM treatments to unique individuals and how that may facilitate greater generalization of treatment effects in the real world. Additionally, the neural mechanisms underlying ABM are poorly understood. The participants in this study gave a list of the 10 things that caused them …

Individual Differences In Influenceability And Anti-Influenceability, Rebecca L. Robinson

Psychology Dissertations - Archive

Using a dispositional strategy, two studies investigated individual differences in three types of influenceability and two types of anti-influenceability. Study 1 replicated the majority of consistent results found in Robinson and Ickes (2016) of different personality traits being predictive of different forms of influenceability. Individuals who reported more instances of self-jeopardizing influenceability tended to (1) have an external locus of control, (2) be more other-directed, (3) have a weaker sense of self, and (4) be more prone to dispositional emotional contagion. Individuals who were prone to susceptibility to peer pressure tended to be (1) low in social desirability, (2) more …

Exploring The Caregiver-Child Relationship In Institutional Care Facilities In South Sudan, Jennifer Joy Telfer

Graduate Theses/Dissertations

Institutional care for children separated from parents is expanding in Africa, but little research exists on caregiving at these institutions. This study explores the caregiver-child relationship in two residential institutions in South Sudan by investigating how caregivers experience their role and how children experience their lives in the institution. Semi- structured interviews assessed 14 caregivers’ backgrounds, parenting experience, attitudes, education, and motivations. The Orphans and Vulnerable Children Wellbeing Tool (OWT) assessed 98 adolescent residents, who also gave feedback about their answers. Caregivers employ parenting styles used by their parents and report treating non-relative children the same as biological children. Children …

Exploring Men's Motivations And Restraints In Repeated Extramarital Sex, Casey Marie Stinley

Graduate Theses/Dissertations

The influence of extramarital sex (EMS) on marriage has been a topic of discussion in the research community for over 30 years. This thesis explored the influences that drive the EMS participants’ decisions, whether to abstain, continue while in the marriage, or to leave the marriage, and, those influences that affect whether they later participate in EMS or not. This study also used individual semi-structured interviews of ex-husbands who have participated in EMS in the past, as well as husbands who are participating in EMS currently. The four men interviewed were from southwest Missouri. The interviews were reviewed to identify …

Enduring Chronic Kidney Disease: An Investigation Of Psychosocial Factors And Life Satisfaction In Older Adults Receiving Dialysis Treatment, Bailee Sobotka

Honors Program: Senior Projects (Public)

Chronic kidney disease is a condition during which the kidneys begin to shut down and no longer filter blood efficiently. Once the disease has progressed far enough, dialysis treatments are mandatory to sustain life. To further understand how older adults receiving dialysis treatments cope with their disease, psychosocial factors were evaluated to investigate possible correlations with life satisfaction using a Life Satisfaction Index Z (LSI-Z). Expected correlations with life satisfaction were sociability, financial satisfaction, importance of spirituality, and activities of daily living scores. Interviews were conducted with 30 dialysis patients and results were analyzed using various statistical measures. Significant correlations …

Assessing The Impact Of Pain On Decision-Making In A Rat Gambling Task (Rgt), Celina Antionette Salcido

Psychology Theses - Archive

Recent clinical assessments using the Iowa Gambling Task have revealed pain can negatively affect decision-making processes, leading to risky or poor decisions. Despite the gain these models have made in further elucidating the cognitive components of pain, they fail to fully address neurobiological factors of decision-making on behavior. As a result, there remains significant limitation in assessing the extent of how acute or chronic pain and the relief of pain with analgesics can affect cognitive abilities. Therefore, we examined the effect of acute and chronic pain on decision processing and the impact of morphine on that decision processing. In this …

Negative Emotionality, Activity Level And Externalizing Problems In Preschoolers: The Influence Of Maternal Mental Health And Education, Ogechi Katherina Nwadinobi

Psychology Theses - Archive

Early childhood temperament has been extensively linked to child externalizing behavioral problems such as aggression, violence, disobedience and antisocial behaviors. Individuals with such behavioral patterns are at greater risk for psychopathologies including oppositional defiant disorder, attention deficit hyperactivity disorder and conduct disorder (Caspi, Henry, McGee, Moffitt & Silva, 1995). The current investigation examined whether the child temperament factors of negative emotionality and activity level predict externalizing problems in preschool. In addition, the study assessed whether maternal mental health and education moderate the relationship between child temperament and externalizing behavior problems. The sample consisted of 201 typically developing children (males = …

Social Reactions To Sexual Assault Survivors Presenting With Ptsd: The Impact Of Survivor Gender And Psychotherapy Treatment-Seeking Status, Shannon Marie Sommer

Theses and Dissertations

The present study examined public perceptions of and willingness to provide social support to survivors of sexual assault presenting with posttraumatic stress disorder (PTSD) based on the survivor’s gender (male vs. female), psychotherapy treatment-seeking status (no treatment vs. dropped out after four sessions vs. still in treatment), and participant gender (male vs. female). Participants (n = 178) read one of six vignettes based on a 2 (gender of survivor of sexual assault: male vs. female) X 3 (treatment-seeking status: no treatment vs. dropped out of treatment after four sessions vs. still in treatment) factorial design describing the life circumstances and …

Exceptional But Not An Exception : Understanding How African American Women Make Their Way, Ebony E. White

Theses, Dissertations and Culminating Projects

Success in the US has been defined in White American terms (Katz 1985; Mangino, 2014), which may not reflect the values of African American women. The goal of this study was to provide practitioners (e.g., counselors, educators, researchers) with a perspective of African American women from their standpoint. African American women who were raised by female heads of households in under-resourced communities were given the opportunity to name, define, and describe their own successes. Using a phenomenological qualitative interview method of inquiry, a semi-structured interview was used to gain a more in-depth understanding of participants’ lived experiences and how they …

Regulating Anger Under Stress Via Cognitive Reappraisal And Sadness, Jun Zhan, Xiaofei Wu, Jin Fan, Jiayou Guo, Jianshe Zhou, Jun Ren, Chang Liu, Jing Luo

Publications and Research

Previous studies have reported the failure of cognitive emotion regulation (CER), especially in regulating unpleasant emotions under stress. The underlying reason for this failure was the application of CER depends heavily on the executive function of the prefrontal cortex (PFC), but this function can be impaired by stress-related neuroendocrine hormones. This observation highlights the necessity of developing selfregulatory strategies that require less top-down cognitive control. Based on traditional Chinese philosophy and medicine, which examine how different types of emotions promote or counteract one another, we have developed a novel emotion regulation strategy whereby one emotion is used to alter another. …

From Foster Care To College: Student Stories Of Success, Tory Nicole England

Graduate Theses and Dissertations

The purpose of this qualitative study was to understand the different factors that empower young adults that were in foster care to be successful in a college environment. It has been documented that foster youth have significant challenges during secondary education (Conger & Rebeck, 2001; Geenen & Powers, 2006). Due to these challenges, foster youth attend and graduate higher education at a lower rate than their peers. The perspectives of foster youth currently enrolled in higher education is critical to determining which factors and programs have helped with their educational success. Five participants completed semi-structured interviews about their secondary education, …

An Initial Application Of A Biopsychosocial Framework To Predict Posttraumatic Stress Following Pediatric Injury, Meghan L. Marsac, Nancy Kassam-Adams, Douglas L. Delahanty, Jeffrey Ciesla, Danielle Weiss, Keith F. Widaman, Lamia P. Barakat

Pediatrics Faculty Publications

Objectives—Each year millions of children suffer from unintentional injuries that result in poor emotional and physical health. This study examined selected biopsychosocial factors (i.e., child heart rate, peritrauma appraisals, early coping, trauma history) to elucidate their roles in promoting emotional recovery following injury. The study evaluated specific hypotheses that threat appraisals (global and trauma-specific) and coping would predict subsequent posttraumatic stress symptoms (PTSS), that coping would mediate the association between early and later PTSS, and that heart rate would predict PTSS and appraisals would mediate this association.

Method—Participants were 96 children hospitalized for injury and assessed at 3 …

Exploring A Multifactorial, Clinical Model Of Thought Disorder : Application Of A Dimensional, Transdiagnostic Approach., Mara Ann Hart

Electronic Theses and Dissertations

Background: Bleuler saw thought disorder as the core defining feature of psychotic phenomena, reflective of the “splitting of the psychic functions” that occurred when, in the process of thinking, one’s ideas and feelings disconnect, becoming fragmented and competing functions. Unfortunately, interest in thought disorder as the conceptual core of psychosis was lost with rise of the modern DSM system, paralleling the shift towards a more simplistic, categorical way of defining psychiatric disorders. Aims: This study examined thought disorder from a dimensional perspective, with the aim of disentangling qualitative heterogeneity and diverse sources of influence. Analyses were based on …

The Relationship Between Trauma And Health-Related Quality Of Life In Lung Cancer Patients : The Potential Protective Role Of Mindfulness., Rene Bayley-Veloso

Electronic Theses and Dissertations

Lung cancer is the most common malignant disease worldwide, and the rapid decline in functioning due to the often-later stage diagnosis can strongly impact a patient’s health-related quality of life (HRQOL). Palliative care, with the aim of improving later-stage HRQOL, is often a main goal of treatment. Compared to other cancer types, patients with lung cancer experience the greatest amount of psychological distress during and after treatment. Prior trauma exposure, and the potentially traumatic nature of the cancer experience, can further complicate HRQOL. Mindfulness, an innate or acquired capacity for sustaining attention in the present moment with qualities of self-warmth …

Cumulative Trauma, Emotion Reactivity And Salivary Cytokine Response Following Acute Stress Among Healthy Women., Yvette Z. Szabo

Electronic Theses and Dissertations

This study furthers understanding of how trauma exposure may be connected to the development and maintenance of poor health by focusing on cytokines, tightly regulated proteins of the immune system. Cytokine responses to acute stress have been associated with the onset of poorer mental health in physically healthy women. The present study examined how two factors recently associated with cytokine reactivity –cumulative trauma and emotion reactivity– are associated with salivary cytokine reactivity among healthy women. Seventy-one women, screened to be physically and mentally healthy, completed a laboratory acute stress paradigm and self-report measures of state emotion and trauma exposure. Participants …

Examining Drinking Motivation, Resiliency, And Alcohol Use Among American Indian And Caucasian College Students, Emily Sargent

Theses and Dissertations

While previous research has suggested American Indians (AI) experience higher levels of alcohol use and related consequences than Caucasians (CA), recent research has demonstrated that AI may actually be drinking at the same or lower rates than CA. AI college students may choose to consume alcohol for different reasons than CA students, referred to as drinking motivation. Resiliency (i.e., experiencing positive outcomes regardless of serious threats) may be one factor that moderates the relationship between specific drinking motives and alcohol use. The current study examined alcohol use, drinking motivation, and resiliency among University of North Dakota (UND) AI (n = …

Sex Differences In Serotonergic And Dopaminergic Mediation Of Lsd Discrimination In Rats, Keli A. Herr

Dissertations

After decades of opposition, a resurgence of interest in the psychotherapeutic potential of LSD is gaining acceptance in the medical community. Future acceptance of LSD as a psychotherapeutic adjuvant may be predicated on knowledge about its neural mechanisms of action. Preclinical drug discrimination assay offers an invaluable model to determine the neural mechanisms underlying LSD’s interoceptive stimulus effects. Unfortunately, current preclinical literature on LSD discrimination is based on results obtained exclusively in male subjects. The present study represents the first known preclinical assessment of possible sex differences in the discriminative stimulus effects of LSD.

Adult female (n=8) and male (n=8) …

A Replication Study Of Personality Types Of Students In A Professional Pilot Baccalaureate Degree Program, Stephanie Gill Fussell

Doctoral Dissertations and Master's Theses

The personality types and learning styles of students have been studied in several populations, yet the research analyzing aviation students is lacking. A replication study assessed the distribution of personality types of students enrolled in the aeronautical science baccalaureate degree program at Embry-Riddle Aeronautical University (ERAU). In addition, this study assessed aviation student learning styles. The Myers-Briggs Type Indicator (MBTI) Form M and the Kolb Learning Style Inventory (KLSI) were used to analyze the personality types and learning styles, respectively. Selection ratio type tables compared the distribution of personality types of aviation students to the traditional college student sample and …

Social Cognition In Children With Attention-Deficit/Hyperactivity Disorder, Elyse Parke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder, which impacts behavioral outcomes, including social functioning. Children with ADHD demonstrate impairment across a number of social domains, including aggressive behavior, poor social skills, and higher rates of Oppositional Defiant Disorder compared to typically developing peers. However, the underlying neurocognitive underpinnings of these poor social outcomes are unclear. Furthermore, little is known regarding the impact of ADHD symptomatology on aspects of social cognition. Inattention, hyperactivity, and impulsivity may differentially impact components of social cognition. Determining whether performance on social cognition tasks is predictive of social skills and problem behaviors is also an area …

Defining Problematic School Absenteeism Using Nonparametric Modeling, Kyleigh Kay Skedgell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Contemporary classification models of school absenteeism often employ a multitier approach for organizing assessment and treatment strategies. Researchers have yet to agree, however, on how to objectively define problematic school absenteeism and identify demarcation points for each tier. The present study aimed to inform a multitier approach by determining the most relevant risk factors for problematic school absenteeism. The most useful targets of assessment for problematic school absenteeism are also addressed. The present study examined problematic school absenteeism defined at three distinct cutoffs: 1%, 10%, and 15% of full school days missed. The present study evaluated interactions among several youth- …

The Moderating Role Of Sex On Gender Role Orientation’S Meditation Of Work-Family/Family-Work Conflict And Satisfaction Outcomes, Deirdre Lynn Paulson-O'Donovan

Dissertations

While biological sex has been examined in the work-family interface, findings have been inconsistent in determining if males and females differ in their experiences of work-family conflict (WFC) and family-work conflict (FWC), and how conflict impacts their job, family, and life satisfaction. These inconsistent findings may be due to the changing roles of men and women, as not all men and women are adhering to traditional gender roles. Furthermore, many researchers have used incorrect terminology, indicating that they examined gender, when they actually assessed sex. Thus, the current study’s purpose was to address the shortcomings of the previous literature by …

Comparing Adult Attachment Styles Among Hispanic And Non-Hispanic Undergraduate College Students Using The Experiences In Close Relationships Revised Structures (Ecr-Rs), Guadalupe Flores Valdez

Dissertations

Research on attachment in adult relationships has included minimal studies to encompass a Hispanic population. Mexican Americans have specific characteristics grounded in historical, demographic, and family contexts which are different from other groups. Therefore, cross-cultural validation of instruments to assess family relationships increases the clinical usefulness of the instruments. The purpose of this study was to compare the equivalence of the factor structure of a widely used family attachment assessment, the Experiences in Close Relationships-Revised Structures Questionnaire (ECR-RS; Donbaek & Elklit, 2014; Parker et al., 2011). This study used principal components factor analysis with maximum likelihood extraction to compare the …
