The Effects Of Training Intensity On Functional Outcome In A Mouse Model Of Stroke, Kelsey Wyman

Honors Projects

Stroke is a leading cause of long-term disability with most patients suffering from persistent unilateral upper-limb impairments. These impairments impede daily living and independence as well as impose many other social and financial burdens. Current rehabilitation methods focus on compensatory movements relying largely on the nonimpaired limb. Unfortunately, the current methods of rehabilitation do not effectively promote full recovery of motor skills on the impaired body side. Rehabilitation in a mouse model of stroke has shown promising results, however, the training regimen used is much more intensive than the rehabilitation that human survivors receive, and the minimum amount of intensity …

Temperature Scale Influence On Perceptions Of Climate Risk, Chelsea Spaman

Honors Theses

This study explored how the use of the temperature scales Fahrenheit and Celsius in climate science communication affects climate change concern. The study specifically targeted Americans due to their familiarity with the Fahrenheit scale, which is not the primary temperature scale used in scientific communication. The study employed a survey, in which the anonymous participants read a short introduction about climate change and temperature rise and then answered a series of questions regarding levels of climate change concern. These questions covered concerns about climate change in general and its potential to harm individual survey participants, flora and fauna, future generations, …

Cultural Bereavement And Resilience In Refugee Resettlement: A Photovoice Study With Yazidi Women In The Midwest United States, Julie A. Tippens, Kaitlin Roselius, Irene Padasas, Gulie Khalaf, Kara Kohel, Elizabeth Mollard, Izdihar (Vianne) Sheikh

Department of Child, Youth, and Family Studies: Faculty Publications

This study explored how ethnic Yazidi refugee women overcome adversity to promote psychosocial health and well-being within the context of U.S. resettlement. Nine Yazidi women participated in two small photovoice groups, each group lasting eight sessions (16 sessions total). Women discussed premigration and resettlement challenges, cultural strengths and resources, and strategies to overcome adversity. Yazidi women identified trauma and perceived loss of culture as primary stressors. Participants’ resilience processes included using naan (as sustenance and symbol) to survive and thrive as well as by preserving an ethnoreligious identity. Findings suggest that women’s health priorities and resilience-promoting strategies center on fostering …

Seductive Details In Training, Megan Paul

Umbrella Summaries

What are seductive details?

In a learning environment, seductive details are interesting but unimportant details that are not necessary to achieve the instructional objective (Garner et al., 1989). The information may be tangentially related to the topic but is not relevant to the main teaching goal. Such details are often included for the purpose of making the topic more interesting and engaging. There are many potential types of seductive details; they can be visual, verbal, or aural—static or dynamic images (e.g., illustrations, photos, animations), written or spoken words (e.g., text, narration), or sounds (e.g., music; Sundararajan & Adesope, 2020).

Only by understanding the ability to take a third-person perspective can we begin to elucidate the neural processes responsible for one’s inimitable conscious experience. The current study examined differences in hemispheric laterality during a first-person perspective (1PP) and third-person perspective (3PP) taking task, using transcranial magnetic stimulation (TMS). Participants were asked to take either the 1PP or 3PP when identifying the number of spheres in a virtual scene. During this task, single-pulse TMS was delivered to the motor cortex of both the left and right hemispheres of 10 healthy volunteers. Measures of TMS-induced motor-evoked potentials (MEPs) of the contralateral abductor …

Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs

Theses and Dissertations

The current literature suggests that subjective time duration could be the common currency used for task choice. However, few studies have been conducted that use non-physical tasks for their task choice options. Thus, the purpose of the current study was to examine if subjective time duration is the common currency for task choice regardless of task type. Participants first provided their subjective time estimates for each of the perceptual-motor and cognitive tasks that have been a priori determined to be at the medium difficulty level. Two cognitive tasks (item generation and math problem task) and one perceptual-motor task with a …

Forms And Frames: Mind, Morality, And Trust In Robots Across Prototypical Interactions, Jaime Banks, Kevin Koban, Philippe De V. Chauveau

Human-Machine Communication

People often engage human-interaction schemas in human-robot interactions, so notions of prototypicality are useful in examining how interactions’ formal features shape perceptions of social robots. We argue for a typology of three higher-order interaction forms (social, task, play) comprising identifiable-but-variable patterns in agents, content, structures, outcomes, context, norms. From that ground, we examined whether participants’ judgments about a social robot (mind, morality, and trust perceptions) differed across prototypical interactions. Findings indicate interaction forms somewhat influence trust but not mind or morality evaluations. However, how participants perceived interactions (independent of form) were more impactful. In particular, perceived task interactions fostered functional …

Social Responses To Media Technologies In The 21st Century: The Media Are Social Actors Paradigm, Matthew Lombard, Kun Xu

Human-Machine Communication

Clifford Nass and his colleagues proposed the Computers Are Social Actors (CASA) paradigm in the 1990s and demonstrated that we treat computers in some of the ways we treat humans. To account for technological advances and to refine explanations for CASA results, this paper proposes the Media Are Social Actors (MASA) paradigm. We begin by distinguishing the roles of primary and secondary cues in evoking medium-as-social-actor presence and social responses. We then discuss the roles of individual differences and contextual factors in these responses and identify mindless and mindful anthropomorphism as two major complementary mechanisms for understanding MASA phenomena. Based …

A Dark Web Of Personality: Network Analyses Of Dark Personality Features And Pathological Personality Traits, Duncan Jordan, Peter K. Jonason, Virgil Zeigler-Hill, E. Samuel Winer, Stephen Fletcher, Dylan Underhill

Faculty & Staff Research and Creative Activity

Network analysis offers an opportunity to gain a more nuanced view of the connections between the darker aspects of personality by examining the interrelationships between the components that make up these constructs. We examined the associations that five dark personality dispositions (i.e., narcissism, Machiavellianism, psychopathy, sadism, and spitefulness) had with pathological personality traits (i.e., antagonism, disinhibition, detachment, negative affectivity, and psychoticism) via network analysis. These dark personality networks were examined in four studies (N = 1,800), wherein the second study attempted to replicate the network from the first study, while the last two studies incorporated more specific and independent measures …

Efficacy Of A Yfv-Specific Monoclonal Antibody In The Treatment Of Yf In A Hamster Model, Ryne Christiansen

Student Research Symposium

The yellow fever virus (YFV) is a flavivirus found mainly in South America and Africa. Infection may result in fever, chills, jaundice, nausea, and vomiting. Outbreaks may have up to 50% case mortality. Although Yellow Fever (YF) is a highly preventable disease through the use of an effective vaccine, there are no approved antivirals for this disease. An effective antiviral is necessary to treat infected individuals in areas where the YF vaccine was not used and an outbreak of YF occurs. In this study, female Syrian golden hamsters were infected with YFV and treated with YFV-specific monoclonal antibodies (mAbs). Weight …

Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman

Honors Thesis

Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …

Understanding Perceptions Of Quality Among Early Childhood Education Stakeholders In Tanzania And Lesotho: A Multiple Qualitative Case Study, Dawn Davis, Debra Miller, Dorothy Mrema, Moikabi Matsoai, Ntsoaki Mapetla, Abbie Raikes, Anna Burton

Department of Child, Youth, and Family Studies: Faculty Publications

Recent global efforts around early childhood education (ECE) have led to increased investments and access, especially in low- and middle-income countries (UNESCO, 2019). As access grows, focus has shifted from enrollment to quality (Gove, 2017). This paper explores how ECE stakeholders in Tanzania and Lesotho define ECE quality. Findings show that stakeholders define quality in similar ways, highlighting the importance of trained teachers who implement specific teaching practices, strong partnerships with families and the community, critical infrastructure, and government support. However, review of the country contexts found that current conditions and support for these quality indicators were lacking.

Early Rearing Conditions Affect Monoamine Metabolite Levels During Baseline And Periods Of Social Separation Stress: A Non-Human Primate Model (Macaca Mulatta), Elizabeth K. Wood, Natalia Gabrielle, Jacob Hunter, Andrea N. Skowbo, Melanie L. Schwandt, Stephen G. Lindell, Christina S. Barr, Stephen J. Suomi, James Dee Higley

Faculty Publications

A variety of studies show that parental absence early in life leads to deleterious effects on the developing CNS. This is thought to be largely because evolutionary-dependent stimuli are necessary for the appropriate postnatal development of the young brain, an effect sometimes termed the “experience-expectant brain,” with parents providing the necessary input for normative synaptic connections to develop and appropriate neuronal survival to occur. Principal among CNS systems affected by parental input are the monoamine systems. In the present study, N = 434 rhesus monkeys (233 males, 201 females) were reared in one of two conditions: as mother-reared controls (MR; …

Exercise Training-Related Changes In Cortical Gray Matter Diffusivity And Cognitive Function In Mild Cognitive Impairment And Healthy Older Adults, Daniel D. Callow, Junyeon Won, Gabriel S. Pena, Leslie S. Jordan, Naomi A. Arnold-Nedimala, Yash Kommula, Kristy A. Nielson, J. Carson Smith

Psychology Faculty Research and Publications

Individuals with Mild Cognitive Impairment (MCI) are at an elevated risk of dementia and exhibit deficits in cognition and cortical gray matter (GM) volume, thickness, and microstructure. Meanwhile, exercise training appears to preserve brain function and macrostructure may help delay or prevent the onset of dementia in individuals with MCI. Yet, our understanding of the neurophysiological effects of exercise training in individuals with MCI remains limited. Recent work suggests that the measures of gray matter microstructure using diffusion imaging may be sensitive to early cognitive and neurophysiological changes in the aging brain. Therefore, this study is aimed to determine the …

Pedagogical Agents, Megan Paul

Umbrella Summaries

What are pedagogical agents?

Pedagogical agents are “lifelike characters presented on a computer screen that guide users through multimedia learning environments” (Clarebout & Heidig, 2012, p. 2568). Pedagogical agents can vary in multiple ways. The following characteristics have been most studied: appearance (two-dimensional [2D] vs. three-dimensional [3D]), eye gaze, facial expression, gesturing, motion, and gender. The simplest pedagogical agent would be a static, 2D image with just text, and a complex agent would be a dynamic, 3D person or character that talks, gestures, and has eye movements and facial expressions.

Why are pedagogical agents valuable?

Pedagogical agents are valuable because …

Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff

Arts & Sciences Graduate Student Theses and Dissertations

Phenylketonuria (PKU) is an autosomal recessive disorder characterized by mutations in phenylalanine hydroxylase genes. As a result, phenylalanine (Phe) metabolism is disrupted, and this amino acid accumulates in blood and tissue (Pietz, 1998; Scriver et al., 2000). Although the most severe symptoms of PKU may be avoided by early detection and treatment, many individuals with early-treated PKU still experience difficulties in executive function, attention, and processing speed (Antenor-Dorsey et al., 2013; Araujo et al., 2013; Christ et al., 2020; Hawks, Strube, Johnson, Grange, & White, 2018; Hood, Grange, Christ, Steiner, & White, 2014; Janos et al., 2012; White et al., …

The Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes

Masters Theses & Specialist Projects

The ability of 16 younger adults to visually perceive distances in depth was evaluated within three environmental contexts (indoors in the dark, indoors in the light, and outdoors). The observers' task was to bisect an 8m distance interval in all contexts using both monocular and binocular vision. In the outdoor environment (a natural grassy field), the observers' judgments indicated perceptual compression of farther distances similar to that obtained in many previous studies. In the indoor lighted environment (a 10.2 x 9.6m laboratory room), the observers' judgments were consistent with perceptual expansion of farther distances. Finally, there was a beneficial effect …

Alcohol Use And Emotion Dysregulation In Adolescence, Shelby King

Masters Theses & Specialist Projects

Underage drinking is a serious public health concern with magnified physical and psychological risks for adolescents. Consequences can include impaired judgement, increased risk for alcohol problems later in life, increased risk of physical and sexual assault, interference with brain development, injuries, and death (National Institute on Alcohol Abuse and Alcoholism, 2021). In a 2019 survey, 29% of high school students reported drinking alcohol in the past 30 days (Centers for Disease Control and Prevention, 2020). Given the high rates of use and adverse effects associated with adolescent substance use, research on risk factors related to alcohol use among this age …

Emotional Support Animals For College Students: Do The Benefits Outweigh The Costs?, Sidney Street

Undergraduate Honors Thesis Projects

Mental health problems have been drastically increasing in recent years among college students. Alongside the rising prevalence of psychological distress, universities have also experienced an increase in requests to have Emotional Support Animals (ESAs) live on campus. To date however, data are scarce on students’ experiences living with and around ESAs. The present study aims to investigate attitudes and perceptions about ESAs, in both owners of ESAs as well as students who do not own an ESA but have interacted with one. Specifically, owners were interviewed to find whether the perceived benefits of owning an ESA outweigh the associated costs …

Influence Of Social Rejection And Borderline Personality Features On Emotion Perception, Ashmita Ghosh

Honors Thesis

Deficits in interpersonal functioning are a core component of borderline personality disorder. Borderline personality disorder is generally associated with misperceptions of social cues including a tendency to perceive others as unfair and rejecting. There is evidence that individuals with subsyndromal borderline personality features also experience these negative outcomes. Furthermore, there is mixed evidence regarding whether individuals with borderline personality disorder have enhanced abilities or deficits in accurately identifying emotions. Therefore, this project examines how social context and borderline personality features affects an individual’s ability to accurately perceive emotions. Participants were randomly assigned to a Cyberball group (inclusion, rejection, overinclusion) and …

The History And Development Of The Hopelessness Depression Theory, Harrison Combs

Student Publications

The hopelessness theory of depression, mainly contributed by Martin Seligman, theorizes that the cause of depression is due to a belief that one has no control over the outcomes of their life, leaving them hopeless. “Learned helplessness” or “hopelessness” is a key phenomenon that helped Martin Seligman develop the theory of hopelessness depression. The current literature review traces the history of learned helplessness, from the first findings of evidence of the phenomenon to the development of the hopelessness depression theory.

Psychometric Validation Of The Brief2 Spanish Version On A Latin Community, Natalia Rich-Wimmer

Doctor of Psychology (PsyD)

Since the early 2000s, the Hispanic population residing in the United States has dramatically grown by 55% (Puente et al., 2015), which increases the importance of understanding how cultural differences may affect neuropsychological test performance. Research demonstrates that pervasive differences exist between the Hispanic community and the dominant culture (Burton et al., 2012). Thus, altering the perception of normative behavior among children (Kärtner et al., 2011). The relative differences in developmental expectations may unfairly disadvantage Hispanic children and potentially lead to the over-pathology of minorities (Burton et al., 2012). The present study aimed to address the potential differences on the …

The Effects Of Carry-On Baggage On Aircraft Evacuation Efficiency, Sang-A Lee

Doctoral Dissertations and Master's Theses

The most frequent obstacle of an aircraft evacuation is the passengers carrying baggage while evacuating. Passengers who insist on taking their carry-on baggage during an emergency evacuation not only slow down the evacuation process but also act as a significant risk to the safety of other passengers. This study investigated the factors that affect passengers’ behavioral intention to evacuate with carry-on baggage and the effects of evacuating with carry-on baggage on the total evacuation time. Overall, two studies were conducted to provide an outline of the factors that affect and affected by carry-on baggage.

Study 1 used an agent-based model, …

Anxiety In Preschool-Aged Children With Autism: Rates, Symptoms, And Predictors, Neilson Chan

Loma Linda University Electronic Theses, Dissertations & Projects

Epidemiological studies indicate that children with Autism Spectrum Disorder (ASD) are at high risk for developing co-occurring anxiety symptoms and diagnosable anxiety disorders, with prevalence rates ranging from 40% to 78%. Further, studies have suggested that children with ASD experience more clinically significant symptoms of anxiety compared to children without ASD as early as toddlerhood. However, few studies have examined the comorbidity of anxiety and ASD in early childhood. In the current study, we included a sample of young children (ages 3 to 5) with ASD (n = 77) and an age-matched typically developing comparison group (n = 55) to …

Sacrifice And Redemption: A New Approach From Mimetic Theory, Nicholas Gregory Roumas

Dissertations (1934 -)

What is the meaning of theories of redemption, and what use do they have? This dissertation answers these questions from the vantage point of two ideas from Girardian Mimetic Theory: the hypothesis that human relationality is rooted in triangular structures of desire, and the hypothesis that the sacrificial death of Christ is what Girard calls a scapegoating event.For Girard, ritual sacrifice is a repetition of an original scapegoating event on which social cohesion depends. With the death of Christ, scapegoating has been denuded and sacrifice rendered inoperable, bringing humanity into a novel historical situation. Using Girard’s early seminal texts alongside …
