Applying Exploratory Learning Methods To Sociopolitical Beliefs And Cognition., Sarah French

Electronic Theses and Dissertations

Americans are polarized along party lines across a variety of sociopolitical issues, including climate change and sustainability issues. Sociopolitical messaging often triggers biased processing that results in defensive rejection or biased elaboration (i.e., counterarguing) of belief-incongruent information. The current research examined whether exploratory learning activities, primarily applied in STEM-education research, can foster belief updating about polarized sustainability issues. Exploratory learning encourages people to engage with learning materials and arrive at their own conclusions before receiving direct instruction/messaging. In two experiments, participants reported their beliefs about carbon taxes and electric vehicle incentives (among other issues) before and after receiving counter-attitudinal persuasive …

Regression Discontinuity Designs Within A Latent Variable Framework: Measurement Considerations For The Accuracy Of The Treatment Effect, Sarah Hammami

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

Regression discontinuity designs are valuable quasi-experimental designs, especially when randomized control/clinical trials are ethically or practically challenging. Latent variables are prevalent in the social, behavioral, and educational (SBE) sciences—measurement assumptions have to be tested and met when using such variables. Not meeting those assumptions leads to biased results and (likely) erroneous inferential making. One way to minimize the impact of measurement assumption violation is to use latent variable modeling such as structural equation modeling (SEM). Soland, Johnson and Talbert (2022) conducted two simulation studies testing the effect of using a sum score (when the assumptions for using such a score …

Reframing Addiction As A Coping Response: A Needed Shift In Modern Public Health Paradigms, Anthony King

UNLV Theses, Dissertations, Professional Papers, and Capstones

What are the primary risk factors that compel one person towards addiction and not another? After decades of research, there is still no clear consensus. Some experts say addiction is a brain disease; others say it is a willful act, or even an outright crime. Nevertheless, the three research studies contained within this dissertation suggest an alternative, more parsimonious public-health-centered framework for viewing addictive behavioral patterns: as a biopsychosocial coping strategy for past and present stressors. In Study 1, this idea was examined by evaluating how symptoms of posttraumatic stress disorder (PTSD) were associated with problem gambling severity, different gambling …

Effects Of Emotional Intelligence And Social Support On The Relationship Between Childhood Maltreatment And Disordered Eating, Rachel Kilby

Undergraduate Honors Theses

Current research has established a connection between childhood maltreatment and eating disorders, and some studies have looked at emotional intelligence or social support as mediators. However, little research has looked at how emotional intelligence and social support work together in the relationship between childhood maltreatment and eating disorders. This study looked at how emotional intelligence and social support act as mediators in this relationship. Undergraduate students (N=134) were administered the Childhood Trauma Questionnaire (CTQ-90), Wong-Law Emotional Intelligence Scale (WLEIS), Difficulties in Emotion Regulation Scale (DERS), Perceived Social Support Scale (PSSS), and the Eating Attitudes Test (EAT-26). Correlations between scales were …

Investigating Bimanual Haptic Exploration With Arm-Support Exoskeletons, Balagopal Raveendranath

All Dissertations

The ability to judge properties like weight and length of hand-held objects is essential in industrial work. Sometimes workers use devices like exoskeletons, which can augment their ability to lift and move heavy objects. Previous studies have investigated the perceptual information available for one-handed weight and length judgments. The current study investigated how blindfolded participants bimanually heft and wield objects to explore haptic information, to perceive object heaviness or length. The study also investigated the effects of using an arm-support exoskeleton (ASE) on the perceived weight of hand-held objects. We empirically tested whether people wield and manipulate objects differently, depending …

Praise In The Collegiate Classroom: How Narcissism, Entitlement, Empathy, And A Desire For Fame Impact Student’S Preferences For Praise, Alexandra Crissman

Student Scholar Showcase

The purpose of this study was to examine the relationship between personality traits, namely narcissism, entitlement, empathy, and a desire for fame, and a preference for public praise in a student population. Past research has shown that those who are higher in narcissism are also higher in entitlement and that these rates have been rising with future generations. Past research has also indicated a negative relationship between narcissistic tendencies and empathy, inferring that those higher in narcissism tend to score lower on empathy measures. In this study, undergraduate students were surveyed online to determine scores on four measures of traits …

The Relation Of Self-Compassion And Belongingness Among Adults From India Living In San Antonio, Tx, Usa, John Baptist

Posters - 2024

Self-compassion, a perspective of self-kindness, mindfulness, and common humanity, is a healthy way of relating to self and is correlated with psychological wellbeing (Neff, 2003). Baumeister and Leary (1995) defined belongingness as a fundamental human need for frequent, affectively pleasant interactions with a few other people in the context of stable, enduring, and affective concern for each other. Self-compassion was inversely related to perceived burdensomeness and thwarted belongingness among college students (Umphrey et al., 2021). A longitudinal study among Asian-American students found that thwarted belongingness and perceived burdensomeness contributed to higher interpersonal shame and depression. An increase in selfcompassion was …

Leveraging Passively-Collected Wearable Accelerometry Data Coupled With Machine Learning To Longitudinally Detect And Predict Major Depressive Disorder, George D. Price

Dartmouth College Ph.D Dissertations

Major depressive disorder (MDD) is a debilitating and heterogenous mental health disorder that is characterized by symptoms including low mood, issues with sleep, psychomotor difficulties, and fatigue. MDD affects one in twenty adults worldwide and has shown increased prevalence in the United States over the past twenty years. As such, efforts to effectively screen, diagnose, and treat MDD are paramount. However, to address these concerns, an increased understanding of an individual’s daily behavior is required, which is not adequately captured by infrequent clinical visits. One such method for consistent, longitudinal observation, passively-collected accelerometry, serves as an observational method for unobtrusively …

The Relationship Between Cognitive Impairment In Psychiatric Patients And Readmission Rate To An Inpatient Facility, Cherilyn Isis Schuff

Theses and Dissertations

The primary intention of this study was to further understand the impact of assessing cognitive impairment in psychiatric patients, as a mediating factor on readmission rates. Mild cognitive dysfunction impacts a patient’s functional outcomes (Bowie & Harvey, 2006; Davis et al., 2012; Marcantonio, et al., 2001). Little information exists to guide best practices in the treatment of adults with cognitive impairment who are hospitalized for acute conditions (Davis et al., 2012). A cognitive impairment may impact patient prognosis and ability to function outside of a setting focused on stabilization. Neuropsychological testing is a valuable tool in predicting a patient’s cognitive …

The Effect Of Email Communication On Professor-Student Rapport, Academic Self-Efficacy, Resiliency, Motivation, And Spirituality, David J. Heim

Graduate Theses/Dissertations

Student retention and success rates are an increasing concern among collegiate administrators and educators. This study examined the influence of a college instructor’s email communications on professor-student rapport, student academic self-efficacy, resilience, motivation, and success. Researchers hypothesized that the student participants who received the encouraging email communications from their professor would demonstrate higher levels of professor-student rapport, higher levels of academic self-efficacy, resiliency, and success compared to the students who receive standard email communications from their professor. Five scales were utilized in this study including Professor-Student Rapport Scale, Academic Self-Efficacy Scale, Academic Resilience Scale (ARS-30), Daily Spiritual Experience Scale (DSES), …

Fluctuations In Alcohol Impairment Of Working Memory Across The Menstrual Cycle, William Mcgarrigle

Theses and Dissertations--Psychology

Behavioral endocrinology studies in women suggest that higher circulating levels of the ovarian sex hormone estradiol (E2) may be linked to better working memory performance, especially under conditions of cognitive impairment (e.g., age-related cognitive decline). Phases of the menstrual cycle characterized by different levels of E2 may therefore influence the degree to which women are vulnerable to alcohol impairment of working memory. The current thesis used a within-subjects design to test the hypothesis that women are less sensitive to acute alcohol-induced impairment of working memory when E2 is elevated during the menstrual cycle. A sample of 75 premenopausal women completed …

The Impact Of A Virtual Wilderness On Subjective Happiness: Enhancing Happiness Through Nature Imagery, Brittany Magid

Antioch University Dissertations & Theses

This dissertation explores the impact of virtual nature imagery on subjective happiness, investigating whether exposure to virtual nature environments can enhance self-reported happiness levels. While direct interaction with natural environments has been linked to increased happiness, this study seeks to evaluate the feasibility of virtual alternatives. Using a quantitative approach, three types of virtual experiences: nature, active control (office environment), and a control condition (gray panel) were compared to assess their influence on acute happiness. Participants (N = 409) were randomly assigned to one of these conditions and completed the Subjective Happiness Scale (SHS) after viewing a 15-second video. Demographic …

Examining Differences In Self-Concept And Language Between Monolingual And Bilingual Undergraduate Students, Marilyn Vega-Wagner

University of the Pacific Theses and Dissertations

The literature is lacking in studies that examine self-concept and language status among individuals older than adolescence. The purpose of this study is to conduct a quantitative nonexperimental comparative design to examine differences in self-concept and language status (monolingual or bilingual) between male and female undergraduate students in California. A total of 97 participants were examined in the study. The researcher conducted descriptive statistics on the demographics as well as a MANOVA and an ANOVA to answer the proposed research question. Based on the findings presented, the researcher failed to reject the null hypothesis of research question 1: There is …

Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker

Murray State Theses and Dissertations

More than half of Americans will be diagnosed with a mental illness in their lifetime (CDC, 2021), yet stigma towards mental health affects both patients and providers. Although programs exist to address stigma, improve cultural competency among providers, and educate families on the importance of support, facilities are often limited on programs they provide due to allocation of resources and funds. Without a shift in treatment and programing, stigma will continue to impact patient care and outcome.

This study explored stigma among mental health providers in rural communities, while exploring potential differences in treatment among patients due to race. Mental …

Detecting Careless Cases In Practice Tests, Steven Nydick

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

In this paper, we present a novel method for detecting careless responses in a low-stakes practice exam using machine learning models. Rather than classifying test-taker responses as careless based on model fit statistics or knowledge of truth, we built a model to predict significant changes in test scores between a practice test and an official test based on attributes of practice test items. We extracted features from practice test items using hypotheses about how careless test takers respond to items and cross-validated model performance to optimize out-of-sample predictions and reduce heteroscedasticity when predicting the closest official test. All analyses use …

The Effectiveness Of Computerized Neurofeedback As An Accompanying Or Alternative Therapeutic Intervention For Pharmacological Treatment In Improving Attention And Other Symptoms For Children With Attention Deficit Hyperactivity Disorder (Adhd), Eqbal Z. Darandari Phd, Nouf F. Alsultan

International Journal for Research in Education

This study aimed to investigate the effectiveness of a treatment program using computerized neuro-feedback in improving attention for children with attention deficit hyperactivity disorder (ADHD). To achieve the aim of the study, the computerized neurofeedback program was applied to (56) children diagnosed with (ADHD), aged between (7-11) years. They were distributed into four groups: the first group was subjected to combined intervention (neurofeedback & pharmacological treatment), the second group was subjected to (neurofeedback only), while the third group was exposed to the intervention using (pharmacological treatment only), and the fourth group was (not exposed to any intervention). Test of Variables …

A Psychometric Analysis Of Natural Language Inference Using Transformer Language Models, Antonio Laverghetta Jr.

USF Tampa Graduate Theses and Dissertations

Large language models (LLMs) are poised to transform both academia and industry. But the excitement around these generative AIs has also been met with concern for the true extent of their capabilities. This dissertation helps to address these questions by examining the capabilities of LLMs using the tools of psychometrics. We focus on analyzing the capabilities of LLMs on the task of natural language inference (NLI), a foundational benchmark often used to evaluate new models. We demonstrate that LLMs can reliably predict the psychometric properties of NLI items were those items administered to humans. Through a series of experiments, we …

A New Method To Determine The Posterior Distribution Of Coefficient Alpha, John Mart V. Delosreyes

Psychology Theses & Dissertations

There is a focus within the behavioral/social sciences on non-physical, psychological constructs (i.e., constructs). These constructs are indirectly measured using measurement instruments that consist of questions that capture the manifestations of these constructs. The indirect nature of measuring constructs results in a need of ensuring that measurement instruments are reliable. The most popular statistic used to estimate reliability is coefficient alpha as it is easy to compute and has properties that make it desirable to use. Coefficient alpha’s popularity has resulted in a wide breadth of research into its qualities. Notably, research about coefficient alpha’s distribution has led to developments …
