The Effects Of Virtual Reality On Motor Performance In The First Person Point Of View, Alina Augustin
Senior Projects Spring 2020
Previous research has shown that visualization is an effective method used to improve motor performance (Ridderinkhof, 2015) and that similar neural pathways are activated while visualizing and performing a task (Decety, 1989). More recent research has begun to look at whether virtual reality similarly improves motor performance (Bideau, 2004). The advantages of virtual reality include the ability to practice without physical exertion (Ridderinkhof, 2015) and a better cognitive understanding of complex tactics (Science-based cognitive assessment & training, 2019). In the current study, the effects of virtual reality and visualization on motor performance in sports is tested based on the success …

Heterogenous Trajectories Of Depressive Symptoms From Adolescence To Young Adulthood: Non-Cognitive Risk Factors And Labor Market Outcomes, Jessica Nicole Gladstone
Publicly Accessible Penn Dissertations
Depression commonly emerges during adolescence and is conservatively estimated to affect up to 12.5% of 12- to 17-year-olds annually (Clayborne, Varin & Colman, 2019). Prior longitudinal analyses have identified significant heterogeneity in the level and growth of depressive symptoms during the transitional period from adolescence to young adulthood. The purpose of this study was to follow one representative cohort during this transition to identify non-cognitive, in-school risk factors for atypical depression trajectories and contextualizing them using impactful labor market outcomes. Latent growth mixture modeling (GMM) was used to assess and classify depressive symptom change trajectories using four occasions of measurement …

Conscientiousness, Extraversion, College Education, And Longevity Of High-Ability Individuals, Peter A. Savelyev
Arts & Sciences Articles
Using the 1922–1991 Terman Life-Cycle Study of Children with High Ability, I investigate the relationship between childhood noncognitive skills, college education, and longevity of a high-IQ population and find a strong relationship between college education and longevity for men. Conscientiousness and Extraversion are strongly related to longevity of men, even though their effects on education are, at best, weak. I demonstrate a number of behavioral mechanisms behind the estimated effects on longevity. I also find that men with higher levels of education and skills have superior health over the lifespan. For women of this historical cohort (born around 1910), who …
Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans,

Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King
UNF Graduate Theses and Dissertations
When the body is faced with threat to life or limb, the autonomic nervous system works to overcome the danger – by either fight, flight, or freezing. While immobility may not appear to be the most logical solution, theories exist that it allows for judgement of the situation and preparation for action. This study investigated the stress response that military veterans, with or without post-traumatic stress disorder (PTSD), demonstrate when shown unpleasant images. Researchers wanted to determine the extent to which veterans would show freezing or immobile responses when under an unpleasant image condition. It was hypothesized that veterans who …

An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith
UNF Graduate Theses and Dissertations
This study investigates the impact of social connectedness (SC) and post-traumatic stress disorder (PTSD) in a military college population, and their relation to physiological measures such as body sway, heart rate (HR), and heat rate variability (HRV). According to previous research, people with PTSD are more likely to exhibit a freezing response to affective images. In the present study, we explore the potential freezing response for military personnel at the levels of PTSD symptom groups and social connectedness. We also investigate the possible buffering effect social connectedness has on the outcome of PTSD and freezing. There was a total of …
Resilience In Adult Women Who Experienced Early Mother Loss,

Resilience In Adult Women Who Experienced Early Mother Loss, Elizabeth Schmitz-Binnall
Antioch University Full-Text Dissertations & Theses
The primary purpose of this dissertation study was to explore levels of resilience in adult women whose mothers died when the participants were children. The death of a mother during an individual’s childhood is an adverse event that can affect all areas of that person’s life. It is intuitive to believe that early mother death would cause long-term effects on the overall resilience levels of the individuals; however, there has been minimal research exploring resilience in this population. With a sample of 245 women throughout the United States, this study used the Connor-Davidson Resilience Scale 25 (CD-RISC-25) to begin investigating …

Student Voices In Teacher Evaluation: A Multilevel, Latent Factor Investigation Of Teacher Quality, Kathleen J. Hoff
Walden Dissertations and Doctoral Studies
Teacher effectiveness is a key driver of student achievement but persistently difficult to measure. Although precollege student surveys are one cost-effective alternative to traditional observation measures, little empirical research has been conducted on their factor structure. The purpose of this study was to investigate the validity of the Tripod Survey, a widely adopted precollege survey, as a measure of teacher effectiveness. The dataset was the Measures of Effective Teaching (Year 1, N = 1,024 Grade 9 classroom sections, 20,500 students; Year 2, N = 488 Grade 9 classroom sections, 8,658 students). The dynamic model of educational effectiveness guided the study. …
Phenotype Extraction: Estimation And Biometrical Genetic Analysis Of Individual Dynamics,

Virginia Commonwealth University
Phenotype Extraction: Estimation And Biometrical Genetic Analysis Of Individual Dynamics, Kevin L. Mckee
Theses and Dissertations
Within-person data can exhibit a virtually limitless variety of statistical patterns, but it can be difficult to distinguish meaningful features from statistical artifacts. Studies of complex traits have previously used genetic signals like twin-based heritability to distinguish between the two. This dissertation is a collection of studies applying state-space modeling to conceptualize and estimate novel phenotypic constructs for use in psychiatric research and further biometrical genetic analysis. The aims are to: (1) relate control theoretic concepts to health-related phenotypes; (2) design statistical models that formally define those phenotypes; (3) estimate individual phenotypic values from time series data; (4) consider hierarchical …

Atheoretical Versus Theory-Based Approaches In Promoting Safer Adhd-Medication Prescribing For Adults, Kathleen A. Fairman
Walden Dissertations and Doctoral Studies
Gaps between treatment guidelines and medical decisions persist despite interventions with physicians, which are mostly atheoretical. The purpose of this retrospective cross-sectional study was to compare atheoretical and theory-based logistic regression models of a binary outcome: potentially unsafe prescribing of attention-deficit hyperactivity disorder (ADHD) medications to adults. Social cognitive theory and self-determination theory provided the framework for the study. Predictors were framed as social cognitive theoretical constructs: knowledge (e.g., physician specialty) and environmental influence (e.g., interventions). Atheoretical hypotheses were based on legislation mandating meaningful use of electronic health records and computerized decision support (CDS). Theory-based hypotheses were derived from literature …

Apr Financial Stress Scale: Development And Validation Of A Multidimensional Measurement, Wookjae Heo, Soo Hyun Cho, Philseok Lee
Journal of Financial Therapy
People usually experience financial stress in managing their financial resources. Despite financial stress’s importance in life outcomes and the need for a comprehensive and theory-based measurement of the construct, few studies have addressed the conceptual issues of financial stress and its measurement. Hence, by borrowing from theories of general stress, this study attempts to fill this gap. Using an expert panel and two separate online survey samples, we developed and validated a novel financial stress scale. A total of 688 responses were used in an exploratory factor analysis and 1,115 responses were used in a confirmatory factor analysis. This multidimensional …

Evaluation Of Modern Missing Data Handling Methods For Coefficient Alpha, Katerina Matysova
Public Access Theses, Dissertations, and Student Research from the College of Education and Human Sciences
When assessing a certain characteristic or trait using a multiple item measure, quality of that measure can be assessed by examining the reliability. To avoid multiple time points, reliability can be represented by internal consistency, which is most commonly calculated using Cronbach’s coefficient alpha. Almost every time human participants are involved in research, there is missing data involved. Missing data means that even though complete data were expected to be collected, some data are missing. Missing data can follow different patterns as well as be the result of different mechanisms. One traditional way to deal with missing data is listwise …

Estimation Of Correlation Confidence Intervals Via The Bootstrap: Non-Normal Distributions,
2019
Old Dominion University
Estimation Of Correlation Confidence Intervals Via The Bootstrap: Non-Normal Distributions, John Mart V. Delosreyes
Psychology Theses & Dissertations
Estimating confidence intervals (CIs) for the correlation has been a challenge. The challenge stems from the metamorphic nature of the sampling distribution of the correlation being bound by-1≤ρ≤1. The nonparametric nature of the bootstrap makes it a good option for estimating correlation CIs. However, there have been mixed results about the robustness of bootstrap CIs for the correlation with non normal data. This had led the literature to suggesting the use of transformation methods to estimate correlation CIs. However, transformation methods carry a risk of the original data being misrepresented. Thus, further investigation of bootstrap CIs for the correlation is …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober
Dissertations, Theses, and Capstone Projects
Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

The Development And Validation Of An Ideal Point Measure Of Work Engagement, Michael M. Denunzio
Dissertations, Theses, and Capstone Projects
Work engagement has been an extremely popular area of research and practice over the past two decades. However, organizational scholars have yet to thoughtfully consider alternative and potentially more appropriate ways of modeling how individuals report their work engagement and, relatedly, measuring the construct. This dissertation seeks to establish and support the position that (1) individuals use an ideal point (vs. dominance) process to identify how engaged they are and respond to work engagement items, and (2) an ideal point framework can be used to develop a construct valid work engagement scale with good psychometric properties. Since no such scale …
Context And Regulation Of Homeschooling: Issues, Evidence, And Assessment Practices,
2019
University of Nebraska - Lincoln
Context And Regulation Of Homeschooling: Issues, Evidence, And Assessment Practices, Janet F. Carlson
Publications of the Buros Center Professional Staff
The article discusses salient factors that influence the current context within which homeschooling occurs. Individual states have applied various approaches to establish regulations that both preserve the rights of homeschooling parents and fulfill the state’s obligation to ensure that its residents receive the education to which they are constitutionally entitled. Case and ethnographic studies or research involving small and selected samples often appear in outlets associated with homeschool advocacy groups or in outlets that are not mainstream. The paucity of empirical evidence derived from methodologically strong research paradigms has led to little certainty about many aspects of homeschooling including its …

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian
Graduate Theses and Dissertations
Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …
