Comparing The Effects Of Square, 4-7-8, And 6 Breaths-Per-Minute Breathing Conditions On Heart Rate Variability, Co2 Levels, And Mood, Joshua Marchant

Theses and Dissertations

Background and Hypotheses: Square and 4-7-8 breathing are popularly promoted by psychotherapists but have little empirical support. We hypothesized that breathing at 6 breaths per minute (bpm) would improve HRV, reduce blood pressure, and improve mood more than either square or 4-7-8 breathing. We also hypothesized square and 4-7-8 breathing would increase end-tidal CO2 (PETCO2). Methods: Eighty-four college students (60% female) had HRV measured at baseline and during 1) square breathing, 2) 4-7-8 breathing, 3) 6 bpm with a 4:6 inhale-to-exhale ratio, and 4) 6 bpm with a 5:5 ratio. We used a 3-lead electrocardiogram to measure HRV and a …

Sustainable Well-Being For Young Adults: An Online Course To Build Ecological And Psychological Flourishing In A Changing Climate, Jeremy Stanley Bekker Mar 2025

Sustainable Well-Being For Young Adults: An Online Course To Build Ecological And Psychological Flourishing In A Changing Climate, Jeremy Stanley Bekker

Theses and Dissertations

Sustainable well-being is "happiness that contributes to individual, community and/or global well-being without exploiting other people, the environment or future generations" (O'Brien, 2010, p. 2). Sustainable well-being education may encourage environmentally sustainable behavior while also teaching people how to live meaningful lives. However, there is currently a lack of research-based disseminable courses for teaching sustainable well-being. We hypothesized that taking the course would result in lower eco-anxiety and higher well-being, as well as increased pro-environmental self-efficacy and pro-environmental values. We used a randomized crossover repeated measures research design to assess pre and post effects. Quantitative results indicated that participating in …

Understanding Avionics Maintenance Training Student Outcomes In A Student-Centered Active Learning Environment, Scott M. Wyman Mar 2025

Understanding Avionics Maintenance Training Student Outcomes In A Student-Centered Active Learning Environment, Scott M. Wyman

Theses and Dissertations

This study examines the effects of active learning compared to didactic methodologies on two soft skills, namely teamwork and self-efficacy using regression analyses and connected letter reports. Learning styles and personality traits were used as predictors. Findings indicate significant interaction effects between methodology, aural learning style, and personality traits on self-efficacy and teamwork ability. The findings highlight the nuanced role of learner traits in shaping teamwork outcomes across instructional methods. While active learning supports soft skills, individual differences must be considered in instructional design to optimize teamwork in technical education settings.
