The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry

Seton Hall University Dissertations and Theses (ETDs)

The inability to remember events experienced very early in life is referred to as Infantile Amnesia (IA) and has been observed in both humans and animals. Over the years interest in the phenomenon waned, but has recently increased with the discovery of new neurobiological methods to study brain function (e.g., Callaghan, Li & Richardson, 2014). The neurobiological mechanism behind IA has yet to be determined, but several innovative theories have been developed with these new research methods. The neurogenesis hypothesis theorizes that increased neurogenesis during early development disrupts previously established memories. The hippocampus, an area that mediates both the memory …

Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders

LSU New Orleans Theses and Dissertations

Stress and anxiety negatively impact the working memory system by competing for executive resources. Broad memory deficits have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing children (M = 11.10 years, SD = 2.95). Results indicate reduced post-stress RSA recovery and overall increased levels of cortisol in children with 22q11.2DS. Additionally, anxiety mediated the relationship between 22q11.2DS and visuospatial working memory impairment. However, there was no indication that stress response physiology mediated this association. …

Hormonal Correlates Of P50 Suppression In Socially Anxious Young Adults, Andrea M. Tountas

LSU New Orleans Theses and Dissertations

Ten to 15% of the population is temperamentally shy and have elevated physiological stress responses to novel social situations. Yet, the neural mechanisms underlying this personality trait are not fully understood (Beaton et al., 2009; Schmidt et al., 1997). Efficiently attending to, acting on, and remembering relevant stimuli and filtering out less important information is critical given the sheer volume of sensory and perceptual stimuli the brain is exposed to.

Relevant stimuli that garner attention are remembered and consolidated with existing memories. Stimuli that do not warrant extended attention are ignored or habituated to in a process underpinned by cortical …

Differential Styles Of Emotional Reactivity And Antisocial Behavior Relative To Post-Traumatic Stress Disorder Symptom Expression In Detained Youth, Molly A. Miller

LSU New Orleans Theses and Dissertations

This study sought to explore whether PTSD symptoms in detained adolescents were differentially related to high and low patterns of emotional reactivity, as determined based on callous-unemotional (CU) traits and emotion dysregulation. Analyses revealed four distinct groups based on these criteria: a low/no trauma control group with few PTSD symptoms, and three groups whose PTSD symptoms were distinguished by symptoms of emotional numbing. The study sought to determine whether these profiles were related to distinct patterns of aggression and delinquency. Results revealed that the low/no PTSD symptom group exhibited the least aggression and delinquency. Further, results indicated that higher CU …

Figure-Ground Organization Using 3d Symmetry, Aaron Michaux, Vijai Jayadevan, Edward Delp, Zygmunt Pizlo

MODVIS Workshop

We present a novel approach to object localization using mirror symmetry as a general purpose and biologically motivated prior. 3D symmetry leads to good segmentation because (i) almost all objects exhibit symmetry, and (ii) configurations of objects are not likely to be symmetric unless they share some additional relationship. Furthermore, psychophysical evidence suggests that the human vision system makes use symmetry in constructing 3D percepts, indicating that symmetry may be important in object localization. No general purpose approach is known for solving 3D symmetry correspondence in 2D camera images, because few invariants exist. Therefore, to test symmetry as a clustering …

An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus

Theses and Dissertations

A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker

MODVIS Workshop

Models of visual attention have been rarely used in real world tasks as they have been typically developed for psychophysical setups using simple stimuli. Thus, the question remains how objects must be represented to allow such models an operation in real world scenarios. We have previously presented an attention model capable of operating on real-world scenes (Beuth, F., and Hamker, F. H. 2015, NCNC, which is a successor of Hamker, F. H., 2005, Cerebral Cortex), and show here how its object representations have been learned. We have used a learning rule based on temporal continuity (Földiák, P., 1991, Neural Computation) …

Maternal, Environmental, And Social Context Predicts Diarrheal Infection Incidence In Young Children In Sundarbans, India, Sohini Mukherjee, Laura M. Glynn

Student Scholar Symposium Abstracts and Posters

Diarrheal infection is the third leading cause of childhood mortality in India and is responsible for 13% of all deaths per year in children under 5 years of age (Lakshaminarayan & Jayalakshmy, 2015). The Sundarbans in West Bengal is amongst the poorest regions of India and is the epitome of abject deprivation and the acute struggle against geographical and socioeconomic challenges. The incidence of diarrhea in this region is considerably high; about 42,000 reported cases occur per month, and one in five diarrhea cases are reported as severe (with blood in stool). In addition, 37% of children hospitalized for ailments …

Gluten-Free And Casein-Free Dietary Intervention For Children Diagnosed With Autism Spectrum Disorder, Avalon Derlacki

Student Scholar Symposium Abstracts and Posters

In the United States, autism spectrum disorders (ASD) had a prevalence of 1 in 150 children in 2000. In the year 2012, the prevalence of ASD in the United States jumped to 1 in 68 children (Centers of Disease Control and Prevention, 2012). Due to the increase in diagnoses of ASD, researchers have sought out different ways to help decrease maladaptive symptoms associated with ASD’s. Many parents of children diagnosed with ASD administer a gluten-free and casein-free (GFCF) diet to their children in hopes of reducing their maladaptive symptoms. The project hypothesis states that if a child under the age …

A New Approach To Measuring Helicopter Parenting: The Multidimensional Helicopter Parenting Scale, Hayley Love

Theses and Dissertations

The purpose of this study was to find a way to measure helicopter parenting that directly reflects its conceptual definition that has been established by Cline and Fay (1990). Literature has pointed to several parenting dimensions that constitute helicopter parenting (Kins & Soenens, 2013; Klein & Pierce, 2009). Rather than looking at helicopter parenting as a qualitatively distinct approach to parenting, this study attempted to show that parenting dimensions established in existing literature are what constitutes helicopter parenting. Helicopter parenting should be looked at as falling on an extreme end of the spectrum of different parenting dimensions. A total of …

Gender Differences In Adhd Diagnosis, Anthony Rizzo

Theses and Dissertations

There is a great disparity in the amount of males diagnosed with ADHD compared to females. This paper reviews a large collection of literature ranging from the history of the disorder, neurological studies, potential genetic differences between genders, as well as potential gender biases. These topics are all examined with the purpose of trying to determine which effect, if any, they may have had in creating the criteria necessary for a diagnosis and how that relates to each gender. The study examined each individual symptom necessary for an ADHD diagnosis and asked teachers to complete a survey designed to attempt …

The Nerve: Associations Between Perceived Parenting Style And Coping With Stress, Lauren Mcgrew

Undergraduate Theses

Throughout a lifetime, women are twice as likely as men to develop an anxiety disorder. Several factors – biological, psychological, and social/environmental – are involved in the mechanisms of anxiety. The present study was designed with particular interest in the association between parents’ parenting styles and daughter anxiety, specifically paternal influences in correlation with how daughters cope with stress. Previous studies suggest that anxious tendencies in parents can be transferred to their children (Ballash, Leyfer, Buckley, & Woodruff-Borden, 2006). Studies have also identified three main parenting styles – authoritarian, authoritative, and permissive – which may also play a role in …

Educating Spouses May Be Key To Helping Veterans, Shawn J. Gourley

Montview Journal of Research & Scholarship

Veterans’ and family members are facing great difficulties when the veteran returns home to transition into civilian life. Marriages are struggling, and families are being torn apart when the veteran returns home with Post Traumatic Stress Disorder (PTSD). Although there are many programs that have been created to educate spouses about PTSD, however, they often fall short of being able to prepare a family for the actual experience of transition. The Department of Veterans Affairs (VA) is starting to come up with programs to help couples and research is starting to gain empirical support; there are still many couples left …

Examination Of Cue-Induced Nicotine Withdrawal Among Humans, Kathleen R. Owens

Senior Honors Projects, 2010-2019

There is copious research investigating the effect of environmental cues on the maintenance of drug behavior in animals, but sparse data exist with regard to humans. In our study, we examined 6 dependent cigarette smokers from James Madison University. We paid participants to use novel lighters that served as audible/tactile cues. After 2 weeks, participants returned to the lab satiated with nicotine for their testing session in which they were presented with the same cue and immediately completed a multiple-choice procedure (MCP) that measured their preferences by offering choices regarding money or the ability to take a cigarette break. Results …

Substance Use Among College Students: Correlations With Intent To Graduate, Academic Integration, And Social Integration, Cecilia M. Clowdus

Electronic Theses and Dissertations

Substance use is one of the greatest concerns for adolescents and emerging adults. The consequences of prolonged substance use can lead to physical, psychological, and financial consequences for those suffering from use as well as their loved ones. One consequence that has not been researched thoroughly is the association between substance use and the decision to leave higher education, which is a decision that could have lasting effects on former students’ ability to obtain satisfactory employment in the future. This research looks at substance use and variables that are associated with the decision to leave college, which are derived from …

The Empathy Project: Using A Project-Based Learning Assignment To Increase First-Year College Students’ Comfort With Interdisciplinarity, Micol Hutchison

Interdisciplinary Journal of Problem-Based Learning

Empathy and interdisciplinarity are both concepts that are current and relevant—across professions, in research, and in academia. This paper describes a large, interdisciplinary, project-based assignment, the Empathy Project, which allows students to delve into and increase comfort and skill with interdisciplinary thinking and collaborative learning, while improving the core college skills of written and oral communication, ethical and quantitative reasoning, and critical thinking. As I revised the assignment based on student feedback and results, I found that group conferences and time in class to work collaboratively were beneficial. Additionally, building increased scaffolding into the assignment, including greater student and group …

College-Going Experiences Of Male Foster Youth Alumni Who Have Stopped-Out Of College, Felipe D. Longoria

Department of Educational Administration: Dissertations, Theses, and Student Research

This qualitative research study examined how foster care experiences and masculinities influenced male foster youth alumni’s decision to go to college. The study also sought to understand the in-and-out-of-college factors that led participants to exit college prematurely. Five participants were each interviewed twice for data collection purposes. Findings from data analysis indicated that establishing and maintaining relationships in college were challenging and affected an already vulnerable population in their help-seeking behavior. Recommendations are offered for higher education professionals and areas for future research are noted.

The Achievement Gap And Students Living In Poverty: The Role Of Core Self-Evaluation And Transformational Leadership In Teachers, India Harris

Dissertations, 2014-2019

Research has shown that the combination of locus of control, self-efficacy, self-confidence, and emotional stability is a good predictor of life success. Until now, this second order factor, called core self-evaluations (CSE) has only been studied in adults. Findings from this study, showed levels of CSE were significantly and positively connected with academic achievement for middle and elementary aged students. CSE appears to play to a similar role between students and academic achievement as it plays with adults and job performance. In this study, the dimensions of transformational leadership were applied to teacher behaviors and students were grouped based on …

The Effects Of Chronic Partial Sleep Deprivation And Chronic Voluntary Alcohol Consumption On Δfos B Accumulation, Kristian Ponder

Masters Theses, 2010-2019

The present study explores the relation between sleep restriction and alcohol use and the neural substrates that result from chronic behaviors. Accumulation of the transcription factors ΔFosB is suggested as a possible outcome of chronic behaviors, such as addiction. Sleep is discussed as possible mediating factor in the relationship between ΔFosB and chronic alcohol consumption. There were four experimental groups in this study: Control (C), Sleep Deprivation only (SD), Alcohol Exposure only (AO), and both sleep deprivation and alcohol exposure (B). Levels of ΔFosB accumulation in the Nucleus Accumbens (NAc) revealed a significant main effect of sleep deprivation, but no …

An Examination Of The Psychometric Properties Of And Validity Evidence For The Alliant Intercultural Competency Scale, Elizabeth L. Smith

Masters Theses, 2010-2019

The alliant intercultural competency scale was developed by Henderson et al. (2015) to measure intercultural competence in students in higher education. Henderson et al. outlined five domains representative of an interculturally competent professional: knowledge, communication, attitudes, professional practice, and negotiated space. In the current study, the AICS was revised (AICS-R) and then evaluated using Benson’s (1998) framework for construct validity. Exploratory factor analysis results suggested a five-factor model strongly aligned with the five aforementioned domains; this provides support for the internal structure of the AICS-R. Scores from the AICS-R were correlated with external measures, and group differences in scores were …

Generalization Of Joint Attention: Using Parent Child Interaction Therapy To Program Social Skills In Children With Developmental Disorders, Thomas E. Rigg

Masters Theses, 2010-2019

Generalization of social behaviors is a vital component of human behavior. Children with Autism Spectrum Disorder often show symptomology that includes impairment in social behavior and failure to generalize behavior on the whole. Initiation of joint attention is a social behavior that can be understood as a behavior cusp and worthy of intervention to promote development. Parent-Child Interaction Therapy has been studied in recent years for its efficacy in treating some dimensions of Autism Spectrum Disorder in children and adolescence. The current study sought to explore the efficacy of Parent-Child Interaction Therapy in promoting the generalization of initiation of joint …

Interteaching: Types Of Prep Guide Questions And Their Effect On Student Quiz Performance, Verena S. Bethke

Masters Theses, 2010-2019

Although previous research indicates that interteaching is an effective alternative to more traditional teaching approaches, not many component analyses of the method exist. For example, although researchers have shown that the prep guide component contributes to the effectiveness of interteaching, no research has directly examined how the content of the prep guides affects learning. The current lab-based study investigated whether having prep guides consisting of lower-level or higher-level questions impacted students’ subsequent quiz performance. We found no significant differences in quiz performance between the two conditions, but several extraneous factors may have impacted the results.

Protecting The Protectors: Enhancing Emotional Well-Being In Law Enforcement, Olivia Gillies

Educational Specialist, 2009-2019

Law enforcement officers face a myriad of stressors, both personally and professionally, and regularly suffer serious outcomes that affect their physical health and psychological well-being. Fortunately, counselors have important skills that can be used to assist officers in building resilience, coping with stress, and managing negative outcomes, such as posttraumatic stress syndrome and interpersonal troubles. This project outlines the various difficulties that law enforcement officers may experience, explores current practices to manage these concerns, and provides a discussion of useful approaches counselors and law enforcement agencies can take in supporting their most valuable assets.

Examining Well-Being Among College Students With Attention-Deficit/Hyperactivity Disorder (Adhd) And Co-Morbid Diagnoses: An Integrative Approach To Understanding Mental Health, Michael T. Strand

Dissertations, 2014-2019

Deficit and dysfunction in college students with ADHD diagnoses are now well studied and known to be commonplace in clinical psychology research literature (see Green & Rabiner, 2014, for review). However, areas of positive functioning and psychological well-being have not been well examined. This dissertation aims to investigate the extent to aspects of well-being may be more or less developed among college students carrying a diagnosis of ADHD, in comparison to their college peers. This examination utilized a subset of data collected from annual national “Healthy Minds” survey of college student mental health in the United States (Eisenberg, D., Hunt, …

More Than Meets The Eye: Taking A Look At Emdr In Trauma-Focused Therapy, Karen M. Engelhard

Educational Specialist, 2009-2019

An abundance of research in trauma-focused therapy has been conducted and continues in the ongoing effort to increase evidence-based approaches to counseling practice. While the therapeutic intervention of Eye Movement Desensitization and Reprocessing (EMDR) has existed for decades and is now widely accepted as an effective treatment method for post-traumatic stress disorder (PTSD), it continues to be surrounded by controversy and criticism as the utility of the eye-movements and its theoretical basis are still not well understood. In this paper, I have discussed theories of trauma and the impact on mind and body, the evolution of EMDR along with its …

The Development Of A Psychological Check-Up: Assessing Character And Well-Being Via The Unified Approach, Lindsay Michele Anmuth

Dissertations, 2014-2019

This dissertation presents a model of assessing and addressing the growing college student mental health crisis (CSMHC), which pertains to the rise of student pathology over time and difficulty meeting the needs of that growing population. A theory driven conceptual paradigm was developed, based on Henriques’ (2011; Henriques & Stout, 2012) Unified Approach to psychology and psychotherapy and, specifically, the Nested Model of Well-being (Henriques, Kleinman, & Asselin, 2014) and Character Adaptation Systems Theory (CAST). Based on those conceptual models and an understanding of college student mental health concerns, the Psychological Check-Up was designed. The Psychological Check-Up consists of a …

Parent-Child Interaction Therapy Informed By Applied Behavior Analysis For Developmental Delay: Parent And Sibling Coaching With Setting Generalization, Mariel S. Cannady

Dissertations, 2014-2019

Parent-Child Interaction Therapy (PCIT) is a well-established, empirically-supported treatment for young children with disruptive behaviors. PCIT was initially designed for treatment of typically-developing children with oppositional and disruptive behaviors. There is emerging support for PCIT as a treatment for behavior challenges seen in children with developmental delays. However, some modifications may be needed to respond to the severity of delay, parent treatment goals, and the function of the challenging behavior. Using a non-concurrent multiple-baseline experimental design, the current study examined the effectiveness of a modified PCIT approach for a preschool child with global developmental delay and co-occurring behavior problems. Modifications …

Ventromedial Prefrontal Cortex Damage Is Associated With Decreased Ventral Striatum Volume And Response To Reward, Maia Pujara, Carissa Philippi, Julian Motzkin, Mustafa Baskaya, Michael Koenigs

Psychology Faculty Works

The ventral striatum and ventromedial prefrontal cortex (vmPFC) are two central nodes of the “reward circuit” of the brain. Human neuroimaging studies have demonstrated coincident activation and functional connectivity between these brain regions, and animal studies have demonstrated that the vmPFC modulates ventral striatum activity. However, there have been no comparable data in humans to address whether the vmPFC may be critical for the reward-related response properties of the ventral striatum. In this study, we used fMRI in five neurosurgical patients with focal vmPFC lesions to test the hypothesis that the vmPFC is necessary for enhancing ventral striatum responses to …

Ambivalent Sexism, Religiosity, And Perceptions Of College Majors As Masculine Or Feminine, Emily Boyles

Senior Honors Theses

This study sought to determine if college students view certain majors as masculine or feminine and if gender perceptions influence their choice of major and subsequent vocation. The methodology included analysis of predictive relationship between scores on the Ambivalent Sexism Inventory (ASI), the Ambivalence toward Men Inventory (AMI), the Revised Religious Fundamentalism Scale (RRFS), and a scale measuring perceptions of majors as masculine or feminine. A total of 492 college students from a large east coast Christian university participated in this study by completing an online survey. Based on the university’s degree offerings, 24 college majors were selected, and students …
