The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures. There have been many efforts in the design and development of robotic systems for applications such as disinfection and eldercare. Healthcare education has seen a lot …


A Cross-Linguistic Study Of Individual Differences In Speech Planning, Benjamin Swets, Susanne Fuchs, Jelena Krivokapic, Caterina Petrone May 2021

A Cross-Linguistic Study Of Individual Differences In Speech Planning, Benjamin Swets, Susanne Fuchs, Jelena Krivokapic, Caterina Petrone

Open Access Publishing Support Funded Articles

Although previous research has shown that there exist individual and cross-linguistic differences in planning strategies during language production, little is known about how such individual differences might vary depending on which language a speaker is planning. The present series of studies examines individual differences in planning strategies exhibited by speakers of American English, French, and German. Participants were asked to describe images on a computer monitor while their eye movements were monitored. In addition, we measured participants' working memory capacity and speed of processing. The results indicate that in the present study, English and German were planned less incrementally (further …

Examining Race And Anxiety Sensitivity As Predictors Of Electronic Cigarette Use And Dependence, Carson Schmitz May 2021

Examining Race And Anxiety Sensitivity As Predictors Of Electronic Cigarette Use And Dependence, Carson Schmitz

Honors Theses

Electronic Cigarettes (e-cigarettes) have gained popularity among U.S. adults with rates of use significantly increasing over the past decade. As such, the current literature has begun to explore factors associated with e-cigarette use in significantly affected populations. Anxiety sensitivity (AS), the fear of the sensations associated with the experience of anxiety, is a known transdiagnostic risk factor for tobacco use. Additionally, higher AS has been shown to be associated with higher levels of e-cigarette use, greater perceived benefits of use, greater positive outcome expectancies, greater perceived risks of use, more quit attempts, and more difficulty quitting. Further, preliminary research focusing …

Psychology: Faculty Scholarship

There has been extensive discussion about gender gaps in representation and career advancement in the sciences. However, psychological science itself has yet to be the focus of discussion or systematic review, despite our field’s investment in questions of equity, status, well-being, gender bias, and gender disparities. In the present article, we consider 10 topics relevant for women’s career advancement in psychological science. We focus on issues that have been the subject of empirical study, discuss relevant evidence within and outside of psychological science, and draw on established psychological theory and social-science research to begin to chart a path forward. We …

Values And Success In Collegiate Athletics, Nathan Shelby Hutchens May 2021

Values And Success In Collegiate Athletics, Nathan Shelby Hutchens

Graduate Theses and Dissertations

The rapid commercialization of intercollegiate sports has changed the landscape of the hiring decisions and methodologies within university-associated athletic departments – especially within the Division I Football Bowl Subdivision (DI-FBS) (Wong, 2017). Most notably and recently, the strategies used to hire athletic directors (ADs) have underwent considerable revision – yet successful hires are far from a sure thing. Many strategies include allusions to leadership style, yet leadership styles are as numerous as there are researchers who study them – and are rarely implemented holistically, thus making their assessment and associated outcomes tenuous at best (Peachey et al., 2015). Hambrick and …

Developmental Dyslexia And Creativity: A Meta-Analysis, Nadyannam M. Majeed, Andree Hartanto, Jacinth J. X. Tan May 2021

Developmental Dyslexia And Creativity: A Meta-Analysis, Nadyannam M. Majeed, Andree Hartanto, Jacinth J. X. Tan

Research Collection School of Social Sciences

Despite difficulties in reading and writing, some research suggests that dyslexia may be related to higher levels of creativity. However, this pattern is not consistently observed. The current research sought to ascertain whether individuals with clinically diagnosed dyslexia exhibit higher creativity than controls through a meta-analysis. Fourteen studies that assessed the creativity of 397 individuals with clinically diagnosed dyslexia and 453 controls were reviewed. Random-effects meta-analysis revealed an overall non-significant difference in creativity scores between those with dyslexia and controls. Additionally, method factors such as the type of creativity task and whether intelligence was controlled for, as well as sample-related …

The Role Of Religious Coping, Age And Meaning In Life In The Development Of Post-Traumatic Growth In Egyptian Breast Cancer Survivors, Nashwa Rashad

Theses and Dissertations

According to the World Health Organization (WHO), breast cancer (BC) is one of the most common types of cancer. Research reported survivors experienced positive changes in their relationship, strength level, and how they admired life after cancer. They said that they recognized elements that promoted post-traumatic growth, such as altering their way of life and accomplishing individually meaningful actions. This literature review reported that religious coping and meaning in life could predict post-traumatic growth. Some sources had conflicted analyses on the effect of age and education on cancer survivors and the development of PTG. This study investigates if religious …


The Effects Of Virtual Nature Exposure On State Social Motivation, Samantha A. Castelblanco May 2021

The Effects Of Virtual Nature Exposure On State Social Motivation, Samantha A. Castelblanco

Electronic Theses and Dissertations

Social health is an important predictor of overall health. Yet, it is an often neglected area of research. Strikingly, social connectedness is associated with a 50% reduction in risk of early death. While a plethora of research evidence supports the beneficial impact of nature exposure on physical and mental health, literature regarding the beneficial impact of nature exposure on social health is scant. In fact, no research to date has investigated the causal influence of nature exposure on social motivation, a construct comprised here of three measures (State Motivation to Foster Social Connections, State Positive Affect, and State Anxiety). The …


Intrinsic Religiousness And Its Relation To Health Outcomes, Joseph Barnet May 2021

Intrinsic Religiousness And Its Relation To Health Outcomes, Joseph Barnet

Electronic Theses and Dissertations

Religiousness, broadly defined, has been shown to be predictive of a variety of health outcomes. Past literature surrounding religiousness research has utilized different definitions and measures for the meaning of religiousness. How religiousness is defined can influence its relationship in relation to health outcomes. The present study utilized a measure for intrinsic religiousness, which is defined as an internalization of the tenets of a particular faith. The present study examined whether intrinsic religiousness predicts problematic or illicit substance use or pornography use in a sample of participants that included mostly undergraduate students from the Appalachian region, as well as some …


It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey May 2021

It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey

Electronic Theses and Dissertations

The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …


Identity-Specific Positive Psychology Intervention For Sexual Minorities: A Randomized Control Trial, Sarah Job May 2021

Identity-Specific Positive Psychology Intervention For Sexual Minorities: A Randomized Control Trial, Sarah Job

Electronic Theses and Dissertations

Sexual minorities experience mental and physical health disparities in comparison to heterosexual individuals due to minority stress (Branstrom et al., 2016; Kerridge et al., 2017; Meyer, 2003). Positive psychology interventions have improved mental and physical health (Antoine et al., 2018; Lambert D'raven et al., 2015), and therefore these interventions have potential to address health disparities. The current study tested an identity-specific intervention (n = 30) to a general positive psychology intervention (n = 30) and a control group (n = 30) among sexual minorities. This built on a recent pilot study which tested the efficacy of an …


Want More Positive Outcomes? Leader Cultural Intelligence And The Facilitation Of A Quality Feedback Environment, Mara Lou Hesley May 2021

Want More Positive Outcomes? Leader Cultural Intelligence And The Facilitation Of A Quality Feedback Environment, Mara Lou Hesley

Theses and Dissertations

The world continues to change, forcing organizational leaders to adapt (House et al., 2014). Leaders with the ability to adapt to a cultural situation that involves people from diverse cultures, otherwise known as culturally intelligent leaders, are predicted to be the most successful in this ever-changing environment (Earley & Ang, 2003; Ang, et. al., 2007). With diversity increasing, (Olson, Green, & Hill, 2008), feedback can no longer be delivered in a “one size fits all” manner (Earley, 1986; Earley & Stubbledine, 1989). Leaders who prioritize being culturally intelligent should contribute to the creation of feedback environments that are personalized and …

Dialogic reading interventions have been used successfully to increase literacy and language skills, including math language. This study aims to investigate whether a dialogic reading intervention will assist children with spatial and numerical magnitude comparison skills learned through a novel adaptive eBook designed to be read together by parents and children. We propose that a dialogic reading intervention used with an adaptive magnitude comparison eBook will improve children’s spatial and numerical magnitude comparison skills and general math skills compared to control groups. Preschool-aged children and their parents (N=27) were randomly assigned to one of three conditions: adaptive magnitude comparison eBooks …


Effects Of Victim Gendering And Humanness On People’S Responses To The Physical Abuse Of Humanlike Agents, Hideki Garcia Goo May 2021

Effects Of Victim Gendering And Humanness On People’S Responses To The Physical Abuse Of Humanlike Agents, Hideki Garcia Goo

Theses and Dissertations

With the deployment of robots in public realms, researchers are seeing more cases of abusive disinhibition towards robots. Because robots embody gendered identities, poor navigation of antisocial dynamics may reinforce or exacerbate gender-based marginalization. Consequently, it is essential for robots to recognize and effectively head off abuse.

Given extensions of gendered biases to robotic agents, as well as associations between an agent's human likeness and the experiential capacity attributed to it, we quasi-manipulated the victim's humanness (human vs. robot) and gendering (via the inclusion of stereotypically masculine vs. feminine cues in their presentation) across four video-recorded reproductions of the interaction. …


The Relationship Between Resilience And Social Support Among College Students During The Covid-19 Pandemic, Amy Baskin May 2021

The Relationship Between Resilience And Social Support Among College Students During The Covid-19 Pandemic, Amy Baskin

Electronic Theses and Dissertations

Due to the unprecedented and unexpected nature of the COVID-19 pandemic, there is little data to date that have investigated the impact on college students. The current study evaluated the relationships between resilience, social support, and distress levels among college students during the COVID-19 pandemic. One-hundred and ninety-one college students in a psychology course completed three measures assessing resilience, social support, and distress during the COVID-19 pandemic. The first hypothesis was that as social support increases, then resilience will also increase in a college population during a worldwide pandemic. A second hypothesis was that as resilience increases, then distress will …


Keeping Count: Studying The Effects Of Previous Sexual History On A Current Coupling, Kaelyn D. Pate May 2021

Keeping Count: Studying The Effects Of Previous Sexual History On A Current Coupling, Kaelyn D. Pate

Electronic Theses and Dissertations

The following thesis details a quantitative study focusing on the sexual double standard and how its impact on sexual attitudes and behaviors has a possible influence on relationship satisfaction. The purpose of this research is to understand how attitudes regarding the prevailing double standard reflect the hesitancy towards having a partner with a previous sexual history as the discussion suggests. There will be a review of previous literature for the traditional, cultural, and even paradoxical aspects that make up the standard. Findings of the study showed that there was no significant relationship found between a respondent’s acceptance of the sexual …

Investigating The Role Of Social Capital And Everyday Communication In Campus Community Resilience During The Covid-19 Pandemic, Kaleb A. Turner May 2021

Investigating The Role Of Social Capital And Everyday Communication In Campus Community Resilience During The Covid-19 Pandemic, Kaleb A. Turner

Graduate Theses and Dissertations

This thesis investigated the role of social capital and everyday communication in campus community resilience capacities during the COVID-19 pandemic. This study conceptualized the university community as a micro-community that experienced sharp disruption as a result of the COVID-19 pandemic. In the same way that traditionally conceptualized communities harness communication to build resilience, this study provides evidence that micro-communities, such as the university campus, have the same potential. Focus groups with students, faculty, and staff, as well as one-on-one semi-structured interviews with students, resulted in 557 pages of single-spaced transcripts that provided rich data to understand this community resilience context. …

Ricketts, Christine Lochner, Dan J. Stein, Jan Stochl, Samuel R. Chamberlain, Jeremiah M. Scharf, Darin D. Dougherty, Douglas W. Woods, John Piacentini, Nancy Keuthen

Psychology Faculty Research and Publications

Body-focused repetitive behavior disorders (BFRBs) include Trichotillomania (TTM; Hair pulling disorder) and Excoriation (Skin Picking) Disorder (SPD). These conditions are prevalent, highly heterogeneous, under-researched, and under-treated. In order for progress to be made in optimally classifying and treating these conditions, it is necessary to identify meaningful subtypes. 279 adults (100 with TTM, 81 with SPD, 40 with both TTM and SPD, and 58 controls) were recruited for an international, multi-center between-group comparison using mixture modeling, with stringent correction for multiple comparisons. The main outcome measure was to examine distinct subtypes (aka latent classes) across all study participants using item-level data …

Students’ use of effective learning strategies facilitates durable learning and academic success. The present research investigates changes in the learning strategies of 2,082 high school students in a dual-enrollment program. All students in the current study were participating in the program for the first time, and data were collected over one academic year via pre- and post-course surveys. It is hypothesized that friction between students’ pre-course learning strategies and the strategy usage expected in the learning environment could promote a change in students’ use and perceptions of effectiveness of learning strategies. Using latent change score models, we investigated changes in …


Circulating Endocannabinoids And Prospective Risk For Depression In Trauma-Injury Survivors, Jacklynn M. Fitzgerald, Samantha Chesney, Tara Sander Lee, Karen J. Brasel, Christine L. Larson, Cecilia J. Hillard, Terri A Deroon-Cassini May 2021

Circulating Endocannabinoids And Prospective Risk For Depression In Trauma-Injury Survivors, Jacklynn M. Fitzgerald, Samantha Chesney, Tara Sander Lee, Karen J. Brasel, Christine L. Larson, Cecilia J. Hillard, Terri A Deroon-Cassini

Psychology Faculty Research and Publications

Biological mechanisms associated with response to trauma may impact risk for depression. One such mechanism is endocannabinoid signaling (eCB), a neuromodulatory system comprised of the CB1 subtype of cannabinoid receptors (CB1R), encoded by the CNR1 gene, and two primary endogenous ligands: 2-arachidonoylglycerol (2-AG) and N-arachidonylethanolamine (AEA), hydrolyzed by monoacylglycerol lipase (gene name MGLL) and fatty acid amide hydrolase (gene name FAAH). Preclinical data suggest that eCB/CB1R signaling acts as a stress buffer and its loss or suppression increases depression-like behaviors. We examined circulating concentrations of the eCBs (2-AG and AEA) days and six months after a traumatic injury …
