Differential Patterns Of Theta Activation Underlying Various Cognitive Control Strategies, Jarrod Eisma

Biomedical Engineering Undergraduate Honors Theses

In this study, EEG was recorded from 157 participants at the University of Arkansas as they performed three computer tasks that tested inhibitory control (Go/Nogo Task), proactive and reactive control (AX-Continuous Performance Task), and resolving response conflict (Global/Local Task- modified Flanker Task). Time-frequency analysis (ERSP) was the primary focus of this study, in order to take advantage of the temporal and frequential characteristics of EEG recordings. The ERSPs and following statistical analysis showed significantly higher midfrontal theta band (4-8 Hz) power values for target trials (those that required more cognitive control) than control trials, which indicated that the procedure was …

Graduate Theses/Dissertations

The ultimate purpose of this study is to provide insight and education to mental health clinicians, politicians and the general public of the numerous effects poverty has on mental health, in addition to the most beneficial ways to combat those insidious effects. The specific barriers met by individuals of low socioeconomic status severely affect psychological and physical health, as well as social and environmental relationships, which therefore diminish overall quality of life. The aim of this study is to examine the effectiveness of implementing a collaborative mental health approach for low income individuals on length of engagement in services and …

Exploring Differential Effects Of Therapeutic Alliance Across Treatment Therapies, Alexandra T. Tonigan

Individual, Family, and Community Education ETDs

Effects of therapeutic alliance has been widely studied for depression, anxiety, and interpersonal problems and been found to have small to moderate positive outcomes. Consistent findings are lacking, however, regarding the relationship between therapeutic alliance, treatment therapy, and client characteristics, in alcohol use disorder (AUD) treatment.

The current paper utilizes data from Project MATCH to assess the differential effects of therapeutic alliance on 12-month alcohol abstinence across clients receiving Cognitive Behavioral Therapy (CBT), Motivational Enhancement Therapy (MET), and Twelve Step Facilitation (TSF) treatment. Moreover, higher order interactions were explored to determine whether such effects differed across client characteristics. This research …

Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna

Dissertations

Research and development of modern psychometric methods such as item response theory have drastically changed the way we understand and carry out the measurement of psychological constructs. Despite this, there has been relatively little adoption by psychological researchers to incorporate these methods into their research. While multiple explanations are surely valid, one oft stated reason is the large sample size requirements of these methods. The sample size requirements of item response theory are needed so that effective estimation of item parameters can be carried out. In an attempt to make these modern measurement methods more accessible and feasible to psychological …

Role-Differentiated Bimanual Manipulations Efficiency: The Difference In Speed For Rdbms Based On Age, Toy-Type, And Infant Hand Preference, Sarai Mikal Cortina

Theses and Dissertations

Role-differentiated bimanual manipulation (RDBM) is a complex behavior requiring the complementary movement of two hands to achieve a common goal. The current study investigated the relation of RDBM efficiency (speed to complete a successful RDBM) with hand preference, toy type (simple/difficult), age, and hand used to perform the RDBM. This study observed 46 infants between the ages of 9 to 14 months, each with a different hand preference category. Changes in RDBM efficiency across time were examined across different hand preference groups for RDBMs performed on simple toys using the right hand. The analysis revealed that early-right preference infants had …

Examining The Performance Of The Alignment Method In Dif Analyses, Paulius Satkus, Christine E. Demars

Department of Graduate Psychology - Faculty Scholarship

The alignment procedure is a new method for multiple group invariance models. An important advantage of alignment over the traditional methods is that alignment does not require full measurement invariance to estimate group means and variances (Muthén & Asparouhov, 2014). Simulation studies have supported that alignment performs adequately in situations when few items are noninvariant (or function differentially across groups – DIF). In most other studies, the tests were simulated to represent attitudinal surveys (e.g., fewer items, continuous data). In this study, we evaluated how alignment would perform with a typical educational cognitive test – 40 items scored dichotomously. Different …

A New Perspective To Measuring Employee Growth: Developing A Successful Aging At Work Scale, Stanimira K. Taneva, Georgi P. Yankov

Personnel Assessment and Decisions

The aging of the world’s population has become a grand societal challenge, which requires an urgent response from researchers, professionals, and the wider society. One way to respond to this challenge is by supporting individuals in sustaining longer and healthier working lives, that is, age successfully. Although the advantages of promoting and enabling successful aging at work have been widely acknowledged, no single instrument for measuring this construct has been published so far. We develop and test in three consecutive samples a two-dimensional successful aging at work scale. This novel instrument is rooted conceptually in the most recent theoretical developments …

Identifying Construct-Irrelevant Variance And Construct Under-Representation As Support Of External Evidence Of Validity, Jennifer Case

Dissertations, Theses, and Capstone Projects

Test validity has commonly been defined in terms of a test measuring what it is supposed to measure, however there has been a century of discussion and debate on test validity and what qualifies as evidence of test validity. Some argue in favor of restricting test validity evidence to that which is internal to the test, such as the test items, while others argue that external information, such as the relationships with other variables, also offers evidence toward test validity. Cronbach and Meehl’s groundbreaking paper in 1955 introduced the concept of the nomological net, which is the construct’s lawful relationships …

Resilience In Adult Women Who Experienced Early Mother Loss, Elizabeth Schmitz-Binnall

Antioch University 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 …

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 …

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. …

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 …

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 …

Evaluation Of Modern Missing Data Handling Methods For Coefficient Alpha, Katerina Matysova

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

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, 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 …
