The Effects Of Fluency Building On Undergraduate Student Performance, Lauren B. Shibley

Dissertations

Online learning has become integral to higher education, with enrollment steadily increasing over the past decade and accelerating during the COVID-19 pandemic. Research highlights the importance of flexibility, learner autonomy, and self-regulated learning skills in this environment, with studies demonstrating that strategies such as mastery-based, self-paced instruction, fluency training, and timely feedback support student engagement and academic success. Early work adapting personalized instruction for online use (Pear & Crone-Todd, 1999) and subsequent studies on fluency practice (Quigley et al., 2018; Urbina et al., 2019) emphasize how these supports can improve concept retention. Despite these advances, more quantitative research is needed …

Psychological Science Faculty Research & Creative Works

This study examines human arm kinematics during overground physical human-robot interaction (pHRI). Previous work showed humans adjust arm stiffness with changing trajectory uncertainty, but the roles of arm kinematics and muscle activation remained unclear. Building on a preliminary study, we analyzed arm movements with more participants (10 individuals) to achieve more reliable findings and examined two potential influences that arose in the preliminary study: the robot's perturbation effect (a brief hand push) and left-to-right trunk sway. Using a linear mixed-effects model, we evaluated the effects of participant, block, and trajectory condition on arm angles. Results showed minimal kinematic contribution to …

Makara Human Behavior Studies in Asia

Environmental identity refers to an individual’s understanding of how their environment shapes their identity and relationships. This connection may cause climate change anxiety and motivate pro-environmental behavior. Using an explanatory, cross-sectional design, we examined whether environmental identity (EI) predicts climate change anxiety (CCA) and whether pro-environmental behavior (PEB) moderates their relationship. Seven hundred sixty-one Filipinos aged 18–25 completed the Revised Environmental Identity Scale, Climate Change Anxiety Scale, and Pro-Environmental Behavior Scale. Our findings revealed a significant positive relationship between environmental identity and anxiety about climate change. However, moderation analysis indicated that environmental identity is only associated with climate change anxiety …

Predicting Job Performance: The Incremental Validity Of Cognitive Reflection Tests Over General Cognitive Ability And Conscientiousness., Olivia Earll 2026 Illinois State University

Predicting Job Performance: The Incremental Validity Of Cognitive Reflection Tests Over General Cognitive Ability And Conscientiousness., Olivia Earll

Theses and Dissertations

Cognitive reflection is the ability to suppress intuitive thinking (Type 1) in favor of deliberative, analytical thought (Type 2). This study investigated cognitive reflection as a predictor of supervisor-rated job performance, exploring its incremental validity over general cognitive ability and conscientiousness. Results indicated that all three variables positively predicted job performance, with cognitive reflection explaining a significant, unique portion of the variance. Exploratory analyses confirmed that this predictive validity remained consistent across industry, age, and sex. Furthermore, cognitive reflection significantly moderated the relationship between general cognitive ability and job performance. These findings highlight the value of deliberative reasoning as a …


Estimating The Average Treatment Effect In Randomized Controlled Trials With Incomplete Covariates, Elizabeth M. Pauley 2026 University of Rhode Island

Estimating The Average Treatment Effect In Randomized Controlled Trials With Incomplete Covariates, Elizabeth M. Pauley

Open Access Dissertations

Randomized controlled trials (RCTs) are commonly used to estimate average treatment effects (ATEs), with baseline covariates often included to improve precision and statistical power for detecting those effects. In applied settings, covariates can be incomplete, and some may moderate treatment effects, leading to heterogeneous treatment effects (HTE). Literature lacks clear direction regarding whether incomplete covariates should be included when estimating the ATE and how different missing data handling methods perform in such conditions. This study aimed to evaluate the performance of four missing data handling methods in RCTs via Monte Carlo simulations, namely listwise deletion (LD), inverse probability weighting (IPW), …

Measures of stress, well-being, and task performance were collected following task completion. Results indicated that neither aesthetic …


Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore 2026 University of Kentucky

Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …
