Conceptualizing Hope As A Virtue, Isabella Musherure, Esther Turahirwa

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

The purpose of this study is to develop a quantitative measure for conceptualizing hope as a virtue while expanding on the psychological framework of hope theory. Hope has predominantly been studied in positive psychology under Snyder's Hope Theory framework (Snyder, 2002). However, its current definition does not encompass a virtuous definition of hope, something that is inherently good. Hope Theory predominately studies hope as a personal trait that promotes individual success and well-being (Schornick et al., 2022). Virtues are a target of much scientific focus and a theoretical framework has recently been proposed to further its empirical study (Fowers et …

Humbly More Religious: The Role Of Humility In Religious Change, Chloe Swanson, Hannah Fuller, Carmen Casper, Isabella Brady

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Recent polls indicate that rates of individuals in the United States who identify as currently religious are declining (Twenge et al., 2016). Events such as COVID-19, presidential elections, and personal adversity affect religious change, likely because such events threaten one's religious worldview. One understudied area of religious change is intellectual humility. Religious change may be more welcome and less destabilizing. We seek to better understand religious change by examining the critical role of humility. In this study, individuals who attended a ex-vangelical conference participated in a year-long longitudinal study where they answered surveys in both 2019 and 2020. These surveys …

Does Visual Dominance Influence Looking Patterns In Adults?, Erin Vokal, Lars Overos, Lauren Tocco

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Language acquisition begins with learning names of common objects by discovering the link between the word and the object. Yet even this is difficult because many objects are often in view when an object's name is spoken. Research shows that children hold objects close to their faces, making them larger in view than other objects, which we call "visual dominance". Infants learn names of objects better when the object named is visually dominant (Yu & Smith, 2012). We want to test if visual dominance aids word learning even when objects are not being held. We will test this by displaying …

Can’T Escape Hell: Negative Religious Beliefs Persist Among Religious Dones, Carmen Casper, Chloe Swanson, Isabella Brady, Hannah Fuller

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Previous research on deidentification from religion explores the residual effects of religion (i.e., religious residue; Van Tongeren et al., 2021). We sought to understand religious residue effects, and predicted that although currently religious individuals would report the highest degree of religious cognition, religious dones would report greater religious cognition than never religious individuals. We examined negative religious beliefs, taboos, pattern detection, and superstitious thinking. A total of 925 participants from the United States and the United Kingdom were recruited through Prolific; 300 currently religious, 298 religious "dones" and 327 never religious (236 male, 578 female, 4 transgender, 1 other, 4 …

Infant Object Transference And Play Preference, Elianna Kuehn, Danielle Mitchell, Grace Sarafa

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

This study investigates the link between virtual object learning and physical object play. This concept is relevant for today's digital culture where infants are routinely exposed to online educational programs (Barr, 2010). Research is unclear, however, about if and how what infants learn about objects on screen (visual preferences) applies to play choices — primary contexts for early learning.

The ability to recognize that an object's image on a screen is the same as the physical object is referred to as object transference (OT). For example, OT would be the ability to see an image of a cow on a …

Infants’ Ability To Associate Objects And Their Names, Nycole Kragt, Chloe Swanson

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Language learning is a complex, dynamic process (Kaplan, 2008). Nevertheless, research indicates that infants as young as 6 months can learn the names for common objects (Bergelson & Swingley, 2012). Learning to associate objects and their names is a difficult task. However, research demonstrates that when infants see objects and hear their names simultaneously across multiple settings, they can begin to associate word-object pairings (Yu & Smith, 2008). This process is called "cross-situational learning." The present study uses eye-tracking to examine how infants accomplish cross-situational word learning. Infants are randomly assigned to one of two conditions: a naming condition where …

Social And Emotional Knowledge In Hippocampal Amnesia, Ashley M. Trainor, Olivia Onderdonk

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

The hippocampus has been found to play a role in general semantic knowledge, but it is unclear if it plays a role in social and emotional semantics. This study seeks to evaluate the role of the hippocampus in social and emotional semantics through the study of patients with hippocampal damage and severe amnesia. Although previous literature has shown that individuals who have damage to their hippocampus show deficits in neutral words, we predict that the hippocampal amnesic group should show the same social-emotional knowledge as the healthy control group. For this study, we investigate this by using more sensitive measures …

Accountability: Construct Definition And Measurement Of A Virtue Vital To Flourishing, Charlotte Vanoyen-Witvliet, Sung Joon Jang, Byron R. Johnson, C. Stephen Evans, Jack W. Berry, Joseph Leman, Robert C. Roberts, John Peteet, Andrew B. Torrance, Ashley N. Hayden

Faculty Publications

Embracing accountability to others for one’s responsibilities within relationships is important for flourishing, yet underexamined. An interdisciplinary team defined the construct of accountability and developed an 11-item single-factor Accountability Scale. In national samples with US census demographic representation (total N = 1257), we conducted psychometric analyses using methods from classical test theory (exploratory and confirmatory factor analyses) and item response theory. The Accountability Scale demonstrated internal consistency, construct validity, test-retest reliability, and incremental validity. Accountability correlated positively with relational variables (agreeableness, empathy) responsibility-oriented variables (conscientiousness, self-regulation), virtues (gratitude, forgiveness, limitations-owning humility), relational repair, perceived meaning presence, and flourishing, inversely with …

The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N = 10, 535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-being, and (2) whether the relation between religiosity and self-reported well-being depends on perceived cultural norms of religion (i.e., whether it is considered normal and desirable to be religious in a given …

Visual Attention Across Language Development, Ayanna Bailey, Chloe Swanson, Meriya L. Zalma

21st Annual Celebration of Undergraduate Research and Creative Activity (2022)

Would you consider yourself a visual learner? Many of us have a sense that what we learn depends on what we see. But how exactly does visual learning happen? How does that change as we grow older? We examined how visual attention changes across development and how that relates to word learning. Previous research on word learning has proposed various ways that people may learn words. However, there is a gap in understanding how visual attention might be crucial for this task, despite the fact that many words are labels for things we see. Previous literature highlights connections between higher …

The Eschatological Hope Scale: Construct Development And Measurement Of Theistic Eschatological Hope, Charlotte Vanoyen-Witvliet, M. Elizabeth Lewis Hall, Julie J. Exline, David C. Wang, Lindsey M. Root Luna, Daryl R. Van Tongeren, David G. Myers, Alexis D. Abernethy, John D. Witvliet

Faculty Publications

This study aimed to expand psychological research on hope by contributing a construct and scale to measure central dimensions of theistic eschatological hope derived from Christian scriptures. Eschatological hope was conceptualized as the anticipation that God will make all things new, raising people to everlasting life with God in joyful celebration, including people from every culture and nation, ending all personal pain and suffering, eliminating all societal evil and harm, and bringing reconciliation and healing to all of creation. We developed the Eschatological Hope Scale with three studies (N = 1,466). Exploratory and confirmatory factor analyses supported the single-factor structure …

Accountability As A Key Virtue In Mental Health And Human Flourishing, John R. Peteet, Charlotte Vanoyen-Witvliet, C. Stephen Evans

Faculty Publications

We propose that accountability plays an implicit, important, and relatively unexamined role in psychiatry. People generally think of accountability as a relation in which one party is held accountable by another. In this paper, we examine accountability as a virtue, drawing on philosophy, psychiatry, and psychology to examine what it means to welcome being accountable in an excellent way that promotes flourishing. When people manifest accountability as a virtue, they are both responsive to others they owe a response, and they are responsible for their attitudes and actions in light of these relationships. Psychiatric treatment often aims to correct disordered …

Examining First Responders’ Mental Health, Taylor Richmond

20th Annual Celebration of Undergraduate Research and Creative Activity (2021)

Terror Management Theory describes the existential angst that humans feel with the understanding that death is truly inevitable and it assists in explaining why humans develop and maintain religious beliefs, how numerous religious orientations address universal existential concerns, and what the social costs and benefits are (Vail et.al, 2010). The purpose of our research was to understand the role of religion (or various coping mechanisms) in terror management processes and managing existential concerns in a community sample (mTurk) and in a sample of participants who regularly face mortality concerns (first responders).

We collected two samples. Participants were randomly assigned to …

Filled And Unfulfilled Hope: The Effect Of Imagery On Self-Regulatory Resources And Emotion, Isabel Santos, Delaney Groves

20th Annual Celebration of Undergraduate Research and Creative Activity (2021)

An important element of human cognition is the ability to imagine and hope for future outcomes. Imagining the future may result in states of hope or hopelessness. Hypertension, respiratory tract infections (Richman et al., 2005), and depression in adolescents (Waszczuk, Coulson, Gregory, & Eley, 2016) have been correlated with hopelessness, whereas positive emotions (Snyder et al., 1991) and lower levels of anxiety and depression (Feldman & Snyder, 2005) have been associated with states of hope. Using an experimental approach, hope evocation decreased anger and anxiety, along with heart rate, compared to rumination following a stressful event (Chadwick et al., 2016). …

The Effects Of Religiousness And Spirituality On Covid-19 Health Behavior Compliance, Kimberly Paquette

20th Annual Celebration of Undergraduate Research and Creative Activity (2021)

Just a little over a year ago, our lives changed as our country fell into panic and all around us businesses and organizations shut down. Everyone but essential workers were supposed to stay home to prevent the spread of the deadly novel coronavirus. Like workplaces, places of worship also closed their doors, which for some was unprecedented. Organizational decisions and norms within these places of worship such as whether to follow executive orders, socially distance, and cleaning may have influenced individuals’ opinions on how to react to the pandemic. If religious communities chose not to follow these guidelines, telling parishioners …

The Benefit Of Gratitude: Trait Gratitude Is Associated With Effective Economic Decision-Making In The Ultimatum Game, Gewnhi Park, Charlotte Vanoyen-Witvliet, Jorge A. Barraza, Benjamin U. Marsh

Faculty Publications

The current research investigated the role of gratitude in economic decisions about offers that vary in fairness yet benefit both parties if accepted. Participants completed a trait/dispositional gratitude measure and then were randomly assigned to recall either an event that made them feel grateful (i.e., induced gratitude condition) or the events of a typical day (i.e., neutral condition). After the gratitude induction task, participants played the ultimatum game (UG), deciding whether to accept or reject fair offers (i.e., proposer: responder ratio $5:5) and unfair offers (i.e., proposer: responder ratios of $9:1, $8:2, or $7:3) from different proposers. Results showed that …

Conceptualizing Spirituality And Religion As Psychological Processes: Validation Of The Factor Structure Of The Bmmrs, Brick Johnstone, Patricia Bruininks, Erin I. Smith, Dong Pil Yoon, Daniel Cohen, Laird Edman, Joseph Bankard, Charlotte Vanoyen-Witvliet

Faculty Publications

This study validated previous principal component analyses of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS) that have been conducted with persons with diverse medical conditions and traumatic brain injuries from diverse cultures (India, US), ethnicities (African American, Caucasian, South Asian), and religions (Christian, Hindu, Muslim). Participants included 398 healthy undergraduate students who completed the BMMRS online. A principal components factor analysis identified a five factor solution accounting for 64.00% of the variance in scores, labelled as: (1) Positive Spiritual Experience; (2) Negative Spiritual Experience/Congregational Support; (3) Forgiveness; (4) Religious Practices; and (5) Positive Congregational Support. The current analysis is supportive …

The Influence Of Hsv-1 Infection On Circadian Rhythms And Behavior In Mice, Lauren Evert, Kevin Catalfano, Victoria Gardner, Anna Lunderberg

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

Herpes simplex virus 1 (HSV-1) infection is a lifelong viral infection that affects approximately half of the human population (McQuillan et al., 2018), yet little is known about its neurological effects. There is correlational evidence that infection with HSV-1 can induce cognitive decline and increased anxiety behaviors (Harris & Harris, 2015; Steel & Eslick, 2015; Tarter, Simanek, Dowd, & Aiello, 2014). In addition, HSV-1 may be associated with disruptions to circadian rhythms because HSV-1 is associated with chronic fatigue syndrome (Bond & Dinan, 2006), the time of HSV-1 infection impacts the viral replication (Edgar, 2016), and HSV impacts CLOCK machinery …

The Role Of Group Pride, Sympathy, & Guilt In Changing Privileged Groups' Views Of Racism, Natalie Trout, Maya Newell, Timothy Bartelds Ii

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

There’s a large gap between the way many Americans (especially Caucasians) and ethnic minorities perceive racism and the reality of experiencing racism. Among many Caucasians, there is a pervasive norm that race and racism are no longer a problem, yet 74% of Blacks polled in 2009 said they were personally discriminated against because of their race (Reid & Foehls, 2010). The goal of this study was to extend prior theory on group emotions to a new domain. We tested whether creating group pride, guilt, and sympathy influenced perceptions of racism in people who belong to a privileged group (Caucasians). We …

How Religious Priming Affects Attitudes About Immigration, Taylor Richmond, Kelly Teahan, Carolyn Priebe, Matthew Severino

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

Many world religions emphasize the importance of charity and hospitality towards those in need, so one may expect there to be greater levels of helpfulness towards immigrants among the religious. However, several social psychological perspectives, including Social Identity Theory (Tajfel & Turner, 1979), Coalitional Psychology (Navarrete & Fessler, 2005), and Terror Management Theory (Solomon, Greenberg, & Pyszczynski, 2000), have found that people are more willing to help in-group members than out-of-group members. Religious texts often vary in theme and research has found that biblical passages about a violent God led participants to be more aggressive, (Bushman. Ridge, Das, Key, & …

How Do Resilience Resources Change In Response To Acute Stress?, Victoria Gardner, Nina Cuthrell, Sydney Tressler

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

People respond to stress in a variety of ways. Resilience, or the ability to bounce back from adversity, is a common response (Bonanno, 2004). Because adversity is common, it is vital to further examine sources of resilience. There is a lack of knowledge related to resilience and everyday stress, thus, we intended to study the relationship between resilience resources and acute stressors. In particular, we wanted to test whether people with higher resilience resources experienced acute stressors as less stressful than others and whether self-ratings of resilience resources would change after exposure to acute stress. Participants are recruited through a …

Disability, Religiousness, & Spirituality, Kimberly Paquette

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

Poliovirus, which is transmitted by a fecal oral route, caused worldwide epidemics in the 20th century, which peaked in the 1940s and 1950s. Today, post-polio syndrome (PPS) is affecting polio survivors and is considered a secondary disability. Individuals who are affected by PPS experience new symptoms similar to those of polio that include weakness in muscles, fatigue, and pain from joint degeneration. Besides these physical symptoms, previous research indicates that polio survivors and PPS affected individuals experience multiple psychological detriments such as anxiety, fear, and depression which could be related to experiencing this secondary disability after recovering from polio. Previous …

Apology And Restitution: The Psychophysiology Of Forgiveness After Accountable Relational Repair Responses, Charlotte Vanoyen-Witvliet, Lindsey M. Root Luna, Everett L. Worthington Jr., Jo-Ann Tsang

Faculty Publications

Apology and restitution each represents wrongdoers’ accountable repair responses that have promoted victims’ self-reported empathy and forgiveness in crime scenario research. The current study measured emotional and stress-related dependent variables including physiological measures, to illuminate the links between predictors of forgiveness and health-relevant side effects. Specifically, we tested the independent and interactive effects of apology and restitution on forgiveness, emotion self-reports, and facial responses, as well as cardiac measures associated with stress in 32 males and 29 females. Apology and restitution each independently increased empathy, forgiveness, gratitude, and positive emotions, while reducing unforgiveness, negative emotion, and muscle activity above the …

Superior Colliculus Lesions Lead To Disrupted Responses To Light In Diurnal Grass Rats (Arvicanthis Niloticus), Andrew J. Gall, Alyssa M. Goodwin, Ohanes S. Khacherian, Laura B. Teal

Faculty Publications

The circadian system regulates daily rhythms of physiology and behavior. Although extraordinary advances have been made to elucidate the brain mechanisms underlying the circadian system in nocturnal species, less is known in diurnal species. Recent studies have shown that retinorecipient brain areas such as the intergeniculate leaflet (IGL) and olivary pretectal nucleus (OPT) are critical for the display of normal patterns of daily activity in diurnal grass rats (Arvicanthis niloticus). Specifically, grass rats with IGL and OPT lesions respond to light in similar ways to intact nocturnal animals. Importantly, both the IGL and OPT project to one another …

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

Faculty Publications

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

Let It Rest: Sleep And Health As Positive Correlates Of Forgiveness Of Others And Self-Forgiveness, Loren Toussaint, Andrew J. Gall, Alyssa Cheadle, David R. Williams

Faculty Publications

Objective: The present study examined forgiveness of others, self-forgiveness, sleep, and health in a nationally representative sample of United States adults. It was hypothesised that sleep would mediate the associations of forgiveness of others and self-forgiveness with health.

Design: A nationally representative survey of 1,423 United States adults.

Main Outcome Measures: Measures included forgiveness of others, self-forgiveness, sleep quantity, sleep quality, psychological distress, life satisfaction, and self-rated physical health.

Results: Forgiveness of others (β = .20, p < .001) and self-forgiveness (β = .11, p < .01) were associated with sleep and forgiveness of others (β = .24, p < .001) and self-forgiveness (β = .27, p < .001) were associated with health. Sleep was associated with health (β = .45, p < .001) and also acted as a mediator of the associations of forgiveness of others (β = .09, p < .01) and self-forgiveness (β = .05, p < .01) with health.

Conclusions: Forgiveness of others and self-forgiveness may attenuate emotions such as anger, regret, and rumination and provide …

The Effects Of Ambient Temperature And Lighting Intensity On Wheel-Running Behavior In A Diurnal Rodent, The Nile Grass Rat (Arvicanthis Niloticus), Garrett M. Fogo, Alyssa M. Goodwin, Ohanes S. Khacherian, Brandi J. Ledbetter, Andrew J. Gall

Faculty Publications

Environmental conditions, such as the light-dark cycle and temperature, affect the display of circadian rhythmicity and locomotor activity patterns in mammals. Here, we tested the hypothesis that manipulating these environmental conditions would affect wheel-running activity patterns in a diurnal rodent, the Nile grass rat (Arvicanthis niloticus). Grass rats are diurnal in the field, however, a subset switch from a day-active pattern to a night-active pattern of activity after the introduction of a running wheel. The mechanism of this chronotype switch remains largely unknown. In the present study, grass rats were presented with running wheels in 12:12 light-dark conditions. First, subjects …

Steadfast Standards Or Fluctuating Fancies? Stability And Change In People’S Mate Criteria Over 27 Months, Carrie A. Bredow, Nicole Hames

Faculty Publications

Although research on mate preferences has been built on the assumption that the criteria people report at one point in time should predict their future partnering behavior, little is known about the temporal stability of people’s standards. Using survey data collected at four time points from 285 originally unmarried individuals, this study examined the rank-order, meanlevel, individual-level and ipsative stability of people’s mate criteria over 27 months. Overall, reported standards exhibited moderate to high baseline stability, with rank-order and ipsative estimates comparable to those reported for personality traits. At the same time, mean- and individual-level analyses revealed small, but significant, …

Enhanced Memory For Fair-Related Faces And The Role Of Trait Anxiety, Gewnhi Park, Benjamin U. Marsh, Elisha J. Johnson

Faculty Publications

The current research examined whether fair consideration—a social norm that people inherently prefer to confirm—would modulate face recognition. Each neutral face was associated with fair or unfair offers via an economic decision task, the Ultimatum Game (UG) task. After the UG, participants were asked to identify the faces of proposers who made different offers. Enhanced memory was observed for fair-related compared to unfair-related faces. Furthermore, high trait anxiety was associated with reduced memory for fair-related faces. These results were further confirmed by signal detection theory. The current research provided initial evidence that people showed enhanced memory for faces that made …
