Caffeine Combined With Sedative/Anesthetic Drugs Used In Neonatal Medicine And Apoptotic Neurotoxicity In Developing Mouse Brain, Omar Hosea Cabrera

Dissertations

Each year, millions of premature babies are exposed to sedative/anesthetic drugs (SADs) in the neonatal intensive care unit (NICU). Acute exposure to SADs triggers widespread apoptosis in the developing brain of rodents and non-human primates. Furthermore, premature infants are administered caffeine (CAF) to treat respiratory dysfunction. Mounting evidence suggests that CAF may be neurotoxic and, when given in combination with SADs, potentiates SAD-induced cell death. However, the apoptotic interaction of CAF and SAD co-exposure is poorly understood. In a series of studies, I report that CAF combined with the NICU SADs midazolam, ketamine, or fentanyl is more neurotoxic to the …

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.

A Mixture Model Demonstrates Use Of Distinct Strategies In A Global Motion Direction Task, Lanya Tianhao Cai, Benjamin T. Backus

MODVIS Workshop

Mixture models are well known in cognitive psychology, less so in vision. Are there cases where the data allow clear testing as to whether different strategies are employed in a task? Most psychophysical measurements manipulate a single staircase variable to map out a monotonic increasing function, but if performance is limited by different mechanisms over the range of the variable, classical fitting could be inappropriate. We present a data set and analyses that confirm the presence of two visual strategies addressing the same task, with the choice of strategies depending on the staircase variable. In a net-motion discrimination task, stimuli …

Immersions In Global Equality And Social Justice: A Model Of Change, Kevin Guerrieri, Sandra Sgoutas-Emch

Engaging Pedagogies in Catholic Higher Education (EPiCHE)

In the work for global equality and social justice, how should “change” be understood? Who determines what must change or be changed? In the efforts to carry out social change, what is the academy’s relationship with the community, society at large, and the broader world? This article parts from these and other key questions and then proposes a model of change that can be used as a lens for examining any project, program, or organization with the aim of creating positive change that is meaningful, sustainable, and holistic. The article provides both an explanation of the underlying interdisciplinary theoretical framework …

Choice-Dependent Perceptual Biases, Long Luu, Alan A. Stocker

MODVIS Workshop

The perceived motion direction of a dynamic random dot stimulus is systematically biased when preceded by a motion discrimination task (Jazayeri and Movshon, 2007). The biases were originally thought to occur because subjects mistakenly reuse the neural read-out optimized for the discrimination task when forming the percept (Fig.1a, Task-dependent model). In a series of experiments, we demonstrated that this explanation is incorrect and that the biases actually result from the conditioning of the percept on the preceding discrimination judgment (Fig1.b, Choice-dependent model). Experiment 1 was aimed at replicating the biases for an orientation stimulus. Subjects first indicated whether the stimulus …

A Learning Model For L/M Specificity In Ganglion Cells, Albert Ahumada

MODVIS Workshop

An unsupervised learning model for developing L/M specific wiring at the ganglion cell level would support the research indicating L/M specific wiring at the ganglion cell level (Reid and Shapley, 2002). Removing the contributions to the surround from cells of the same cone type improves the signal-to-noise ratio of the chromatic signals. The unsupervised learning model used is Hebbian associative learning, which strengthens the surround input connections according to the correlation of the output with the input. Since the surround units of the same cone type as the center are redundant with the center, their weights end up disappearing. This …

Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba

MODVIS Workshop

Building on our presentation at MODVIS 2015, we continue in our quest to discover a functional, computational, explanation of the relationship among visual attention, interpretation of visual stimuli, and eye movements, and how these produce visual behavior. Here, we focus on one component, how selection is accomplished for the next fixation. The popularity of saliency map models drives the inference that this is solved; we suggested otherwise at MODVIS 2015. Here, we provide additional empirical and theoretical arguments. We then develop arguments that a cluster of complementary, conspicuity representations drive selection, modulated by task goals and history, leading to a …

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) …

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 …

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 …

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 …

Socio-Cultural Experiences And Openness To Music Genres, Britni Heustis

Honors Program Theses and Projects

This project explored the relationship between socio-cultural experiences and openness to listen to a variety of international music genres. These genres included: Korean Pop, Classical, African Beats, Latin, Tropical, Reggae, Rap, Indian, and Jazz. Participants (n = 298) were recruited online utilizing Mechanical Turk. All participants were eighteen years of age or older. A significant positive correlation was found between socio-cultural experiences and openness to global music genres. Preliminary analysis is discussed for the various components of the socio-cultural exposure scores (cultural experiences). A potential implication of this study is the recognition of the importance of, as well as the …

Crossing The Line? Victim And Defendant Attractiveness Impacts Juror Perceptions In A Stalking Case, Kristin M. Purnell

Honors Program Theses and Projects

Stalking cases can often be ambiguous, which makes it difficult for jurors to determine if the defendant crossed the line from romantic courtship to stalking. The present research used a mock juror experiment to assess the effect of victim attractiveness and defendant attractiveness on juror decision-making in a stalking case. Community member participants (N = 296) read a stalking trial summary in which we manipulated attractiveness of the victim and defendant via images and asked participants to rate perceptions such as credibility, sympathy, and stalking typicality. We found a main effect of defendant attractiveness such that a more attractive defendant …

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 …

Spiritual Attitudes And Values In Young Children, Maryl Deputy, Jessica Devivo, Nicole Fasolo, Lydia Jones, Debbie Martin, Victoria Pennant

Montview Journal of Research & Scholarship

Research has shown that spirituality is an important function of a child’s social, emotional, and personal development. Nevertheless, minimal research exists on spiritual attitudes and values in young children. This study examined children’s development and spirituality using a modified version of the Attitudes and Values Questionnaire (AVQ). The Australian Council for Educational Research (ACER) developed the AVQ with the dimensions of Conscience, Compassion, Social Growth, Emotional Growth, Service to Others, Commitment to God, and Commitment to Jesus. Commitment to God and Commitment to Jesus were optional dimensions later added by ACER to focus specifically on Christian principles. Following permission from …

RESULTS: There were no differences in motivation, affective response, or intention to …

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 …

Standing Up Or Standing By: Examining The Bystander Effect In School Bullying, Scott M. Fluke

College of Education and Human Sciences: Dissertations, Theses, and Student Research

School bullying represents a serious mental health problem for youth in the United States. Bullying is a social phenomenon that is affected by the social context in which it occurs. Bystanders (i.e., individuals who witness bullying), are present in the vast majority of bullying situations. When bystanders choose to intervene on behalf of the victim, they are able to stop the bullying about 50% of the time. Unfortunately, bystanders rarely stand up for victims, instead frequently choosing to help the perpetrator or passively observe the bullying situation. Researchers have identified the bystander effect (i.e., the inhibitory effect of other bystanders …

Correlates Of Appearance And Weight Satisfaction In A U.S. National Sample: Personality, Attachment Style, Television Viewing, Self-Esteem, And Life Satisfaction, David Frederick, Gaganjyot Sandhu, Patrick J. Morse, Viren Swami

Psychology Faculty Articles and Research

We examined the prevalence and correlates of satisfaction with appearance and weight. Participants (N = 12,176) completed an online survey posted on the NBCNews.com and Today.com websites. Few men and women were very to extremely dissatisfied with their physical appearances (6%; 9%), but feeling very to extremely dissatisfied with weight was more common (15%; 20%). Only about one-fourth of men and women felt very to extremely satisfied with their appearances (28%; 26%) and weights (24%; 20%). Men and women with higher body masses reported higher appearance and weight dissatisfaction. Dissatisfied people had higher Neuroticism, more preoccupied and fearful attachment …

Possible Causes Of Increased Domestic Violence Among Military Veterans: Ptsd Or Mefloquine Toxicity?, Shawn J. Gourley

Montview Journal of Research & Scholarship

After more than a decade at war, our returning service members and their families are facing enormous amounts of difficulty when returning home. PTSD and TBI, the signature wounds of these wars, have been well covered in the media. The family struggles have remained hidden and mostly undiscussed. These families are facing very specific issues in military relationships like infidelity, substance misuse, and intimate partner violence; the latter of which military families are three times more likely to experience when compared to the civilian population. There is a potential effect on caregiver burden in the role of PTSD as a …

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 …

The Relationship Between Mortality Salience And The Two Subtypes Of Narcissism, Rianna H. Yung

Senior Honors Projects, 2010-2019

Terror management theory (TMT) posits that a psychological conflict (“terror”) is created when human beings are reminded of their own mortality (Solomon, Greenberg, & Pyszczynski, 1991). This experimental study examines whether the impact of mortality salience on self-esteem is moderated by individual differences in narcissism. There are two subtypes of narcissism, namely grandiose narcissism and vulnerable narcissism. Grandiose narcissism is associated with higher self-esteem, whereas vulnerable narcissism is associated with lower self-esteem. Participants (N = 437) completed an online survey that consisted of the Rosenberg Self-esteem Inventory, the Pathological Narcissism Inventory, a mortality salience manipulation or the control task, …

Understanding Identity And Personality Authenticity Of Engineering Students, Kylie D. Stoup

Senior Honors Projects, 2010-2019

Women are underrepresented in engineering, with 18-20% of engineering students being women¹. We, therefore, used the framework of identity theory and self-concept differentiation to better understand female and male engineering student retention. An exploratory approach is used to measure freshman and senior engineering students’ personality and authenticity of personality across engineering and non-engineering contexts. First, we found personality profiles among engineering freshmen and seniors in engineering settings, and then compared them to their personality in nonacademic settings for authenticity purposes. Big 5 Personality and Authenticity scale were methods used through a survey to determine personality and authenticity in …

Exploring The Associations Among College Students Self-Reported Resilience, Coping Behavior, Goal Orientation And Passion For Academics, Sara C. Mcmillan

Senior Honors Projects, 2010-2019

The current study expanded research on resilience by examining associations between resilience, coping behaviors, goal orientation and passion for academics of college students. Participants were 252 undergraduate students (147 female, 105 male) with an average age of 19. Three resilience scales assessed in this study, Resilience Scale for Adults, Brief Resilience Scale and the Academic Resilience Scale, were positively correlated with each other. Resilience was positively correlated with adaptive coping, learning goals and harmonious passion. Resilience and maladaptive coping were negatively correlated. This study connected variables not previously examined in a college student population. Limitations and implications of the findings …

A Comparison Of Combined Versus Individual Cognitive Coping Strategies For Managing Pain, Grant Pointon

Senior Honors Projects, 2010-2019

Several cognitive coping strategies for reducing pain sensation have been identified, but their effects have traditionally only been examined in isolation. The current investigation instead compared the effectiveness of traditional cognitive coping strategies based upon imagery and pain acknowledgement/attention against an “integrated” strategy (that required both strategies to be used in combination) within a cold pressor test (CPT). Participants (N = 24, M_age= 19.46, SD = 1.47) underwent a baseline condition followed by counterbalanced strategy trials: imagery, attention, & integrated condition. Tolerance times, pain ratings, and perceived control ratings were recorded. The imagery condition had lower pain …

Does Passion Predict Enjoyment And Performance In An Interteaching-Based Course?, Allison T. Piotrowski

Senior Honors Projects, 2010-2019

The present study sought to examine whether passion for academic activities predicted students’ enjoyment of and performance in an interteaching-based course. Although previous studies have shown interteaching to produce better student-learning outcomes than lecture, few studies have examined factors that predict how students respond to interteaching. Because people who have higher levels of harmonious passion tend to approach activities in an open and flexible manner, we predicted that harmonious passion for academic activities would predict increased enjoyment of and performance in an interteaching-based course. In contrast, because people with higher levels of obsessive passion approach activities in a rigid and …
