The Effects Of Multicollinearity In Multilevel Models, Patrick Carl Clark Jr.
The Effects Of Multicollinearity In Multilevel Models, Patrick Carl Clark Jr.
Browse all Theses and Dissertations
This study examined a method for calculating the impact of multicollinearity on multilevel modeling. The major research questions concerned a) how the simulation design factors affect (multilevel variance inflation factor) MVIF, b) how MVIF affects standard errors of regression coefficients, and c) how MVIF affects significance of regression coefficients. Monte Carlo simulations were conducted to address these questions. Predictor relationships were manipulated in order to simulate multicollinearity. Findings indicate that a) increases in relationships among Level 1 predictors and also relationships among Level 2 predictors led to increased MVIF for those specific variables, b) as MVIF increases for a predictor, …
Spatialized Audio And Landmarks In Team Navigation, Andrew Hampton
Spatialized Audio And Landmarks In Team Navigation, Andrew Hampton
Browse all Theses and Dissertations
Using data collected from a prior study that established the benefit of spatialized audio on team navigation, the current paper examines the underlying mechanisms by which that benefit arose. With linguistic measures extracted from trial transcripts, I study emergent patterns of conversation for four dyads as they attempt to rendezvous in an immersive virtual environment. Spatialized audio is compared to landmarks, traditionally viewed as integral to navigation tasks, on the basis of coordination and strategy. Analyses reveal that spatialized audio creates a decreased need to speak overall. Paired with the performance advantage, this creates a more linguistically efficient task structure. …
Examination Of The African-American Father-Daughter Relationship: Application Of The Marschack Interaction Method, Amber N. Thornton
Examination Of The African-American Father-Daughter Relationship: Application Of The Marschack Interaction Method, Amber N. Thornton
Browse all Theses and Dissertations
Early research on the Black family implied an enormous lack of African-American father presence and involvement among African-American fathers. However, more current research negates those findings by highlighting the contributions African-American fathers make when parenting their children (Coley, 2003; Cooper, 2009; Mandara, Murray & Joyner, 2005). In spite of facing unique psychological and social challenges, such as disproportionate levels of poverty, and race related social barriers, such as the invisibility syndrome (Franklin & Boyd-Franklin, 2000), researchers who have studied the African-American father-daughter dyad have discovered that this relationship has many benefits for African-American girls, including cognitive and academic enhancements, reductions …
Impact Of Binaural Beat Technology On Vigilance Task Performance, Psychological Stress And Mental Workload, Elizabeth Ann Shoda
Impact Of Binaural Beat Technology On Vigilance Task Performance, Psychological Stress And Mental Workload, Elizabeth Ann Shoda
Browse all Theses and Dissertations
Currently, there is only one published study examining the impact of binaural beats on the performance of a laboratory vigilance task, however this study had mixed results and left many questions unanswered. I further examined this phenomenon by using a successive vigilance task, between-subjects design, and a control condition to determine whether beta frequency binaural beats could affect vigilance performance over time and across conditions. I hypothesized that participants listening to beta binaural beats would have more hits and fewer misses on the vigilance task than participants in the control condition. In addition, I hypothesized that participants listening to beta …
Heuristics: Bias Vs. Smart Instrument. An Exploration Of The Hot Hand, Jehangir Cooper
Heuristics: Bias Vs. Smart Instrument. An Exploration Of The Hot Hand, Jehangir Cooper
Browse all Theses and Dissertations
Classical perspectives on judgment and rationality view heuristics as erroneous, leading to suboptimal judgments. Conversely, ecological perspectives view heuristics as smart mechanisms that result in good judgments in the face of uncertainty. Our research focused on the hot hand heuristic and examined it using non-linear analysis methods. This research attempted to answer two questions. The first question concerned the applicability of frequency analysis methods for detecting constraints (such as the hot hand) or structure in a time series of binary data, which we attempted to investigate through Monte Carlo simulations. We found that this method was sensitive enough to detect …

Disability Identity Formation In People With Severe Mental Illness And Treatment Seeking And Compliance: A Participatory Action Research Study, Kimberly M. Sommers
Browse all Theses and Dissertations
The study of facilitators of treatment seeking and compliance in people with severe mental illness represents a significant gap in the current literature. The present study, using a Participatory Action Research (PAR) approach, attempted to identify facilitators to treatment seeking and compliance through the lived experiences of people living with severe mental illness. Interviews were used to gather information about the experience of people with severe mental illness regarding disability identity development, recovery, interactions with treatment and treatment providers, the experience of being diagnosed with a severe mental illness, and the impact of psychiatric disability on family, friends, and functioning. …
Personality's Influence On Burnout: An Unfinished Puzzle, David Andrew Periard
Personality's Influence On Burnout: An Unfinished Puzzle, David Andrew Periard
Browse all Theses and Dissertations
This study examines the relationship between emotional exhaustion-the main component of burnout-and several facets of the Big Five Factors of personality. Previous research has found small relationships between the Big Five Factors and emotional exhaustion. I hypothesized that the facets of trust, cooperation, orderliness, and self-discipline will have curvilinear relationships with emotional exhaustion. The facets of vulnerability and depression were also hypothesized to moderate the curvilinear relationships between orderliness and self-discipline and emotional exhaustion. Regression analyses only found a curvilinear relationship between order and personal burnout when vulnerability was controlled for. A significant quadratic-by-linear interaction was found between order and …

Job Crafting: The Pursuit Of Happiness At Work, Cristina D. Kirkendall
Browse all Theses and Dissertations
Traditional job satisfaction theories focus on either environmental causes or stable underlying personality characteristics as determinants of job satisfaction, giving very little attention to the possibility that employees may be able to affect their own job satisfaction levels. Recent research on job crafting, however, has provided a source of optimism for changing job satisfaction levels. Job crafting is the processes by which employees actively shape their job to fit their individual needs and unlike the traditional models, it offers hope to those employees that work in a dissatisfying environment or whose personalities may not predispose them to high job satisfaction. …

Browse all Theses and Dissertations
The purpose of this study was to test the various models describing the Flash Lag Effect (FLE). Beginning with the initial work of Nijhawan (1994), several models have emerged endeavoring to explain the FLE (e.g., Eagleman & Sejnowski, 2000; Whitney, 2000; Baldo & Caticha, 2005). Two series of studies comprising 11 separate experiments were undertaken to differentiate these models, with a particular focus on the neural network model of Baldo and Caticha (2005). The experiments included the three primary FLE experimental paradigms: continuous motion (CM), flash-initiated (FIC) and flash-terminated (FTC). Ninety-three participants made observations in these three paradigms using a …

The following study attempted to determine the effectiveness of the Preventing Abuse in the Home (PATH) batterer's intervention program from the perspective of the partners of men enrolled in the program. The partner's perspective was obtained through the collection of qualitative data from interviews conducted with women who were currently or recently involved with men who had been participating in the PATH program for a minimum of 16 weeks. Interview questions were created based upon several variables including review of empirical literature and specific questions that researchers were interested in addressing in regards to PATH. Results highlighted the various types …
Mindfulness-Based Interventions And Processes Of Change: A Conceptual Model For Clinicians, Shalagh A. Frantz
Mindfulness-Based Interventions And Processes Of Change: A Conceptual Model For Clinicians, Shalagh A. Frantz
Browse all Theses and Dissertations
Mindfulness-based interventions are receiving a great deal of attention from clinicians and researchers and research in this field is increasing dramatically in the past decade. Much of this research is consistent with positive psychotherapeutic outcomes for a wide range of presenting clinical issues. As with any seemingly successful psychotherapeutic treatment, it can be helpful to understand the processes of change underlying mindfulness-based interventions that are responsible for observed positive outcomes. In doing so, the effective components of an intervention can be refined and perfected, while components deemed unneeded can be appropriately discarded. This dissertation critically reviews the literature's current understanding …

Prospective memory is the ability to remember to do something in the future, also known as meta-remembering. Prospective memory is required to complete certain tasks, such as remembering to take medications, pay bills, and perform various activities of daily living. The Memory for Intentions Screening Test (MIST) is a standardized objective assessment of prospective memory that has been utilized to document impairment in prospective memory in various clinical populations such as Alzheimer's Disease, mild cognitive impairment, mild traumatic brain injury, Human Immunodeficiency Virus (HIV), schizophrenia, and Parkinson's Disease (Raskin, 2009). The current research project utilized the MIST to identify the …

A pilot study was completed to determine the effectiveness of Focused Brief Group Therapy (FBGT; Whittingham, 2008) in a college counseling center. The study focused on individuals with elevated scores on scale 8, also known as the socially uninhibited subtype, of the Inventory of Interpersonal Problems. This scale has been described by researchers as potentially problematic in treatment (Burlingame, 2005) and also appeared in high numbers as referrals at a mid-western college counseling center. Pre-existing data from the Inventory of Interpersonal Problems (IIP-32; Horowitz et al., 2000) and the Counseling Center Assessment of Psychological Symptoms (CCAPS; Center for Collegiate Mental …

The Role Of Hope And Resilience In Pediatric Obesity Intervention Outcomes, Brigitte Dawn Beale
Browse all Theses and Dissertations
Childhood obesity is a major health concern in the United States (McClanahan, Huff, & Omar, 2009). In recent years, the prevalence of pediatric obesity has stabilized. However, a substantial decrease in obesity rates has not yet occurred, nor has the gap of health disparity been closed amongst ethnic groups experiencing obesity. African-American and Hispanic youth continue to experience obesity at substantially higher rates than other ethnic groups (Robert Wood Johnson Foundation, 2012). The purpose of this study was to examine correlations between Positive Psychology constructs and pediatric obesity intervention outcomes. A single-participant research design was utilized to compare baseline outcomes …

This study was designed to examine how skin tone discrimination affects African American women. The phenomenon of colorism is not exclusive to African American women, but the manifestations on this group are diverse, and the effects are unique. Previous research has shown that the experience of colorism is pervasive within the Black community and that most African American women have been, either culturally or personally, affected by intra-racial discrimination. This body of work used a focus group to investigate the experiences of African American women who were categorized according to their self ascribed skin tone group. It specifically explored skin …

There is a gap in the current literature concerning the study of university students with mental illness. Particularly, very few qualitative studies have been conducted in which interviews with university students with mental illness have yielded knowledge about the population's experiences and needs. The present study, employing a Participatory Action Research (PAR) approach, was designed to promote a more accurate perception of the lives of university students with mental illness by allowing the voices of members of this group to be heard. Eight matriculating university students who self-identified with mental illness participated in this exploratory PAR initiative. The study involved …

While group therapy appears to be gaining popularity at University Counseling Centers, scant research has been done on Latino students' group therapy participation. The present study examined the barriers that Latino college students face in considering whether to join group therapy. Participants (N=81) completed three measures. The first measure was a demographic questionnaire. The second measure was a modified version of the Barriers Scale, originally developed by Harris (2012), a 44-item survey in which participants were assessed in terms of: their willingness to consider group therapy, group therapy modality preferences, expectations of group therapy, expectations of group members, expectations of …

Objective: Our purpose was to discuss alternative principles of design (emergent features and perceptual objects) for analogical visual displays, to evaluate the utility of four different displays for a system state identification task, and to compare outcomes to predictions derived from the design principles. Background: An interpretation of previous empirical findings for three displays (bar graph, polar graphic, alpha-numeric) is provided from an emergent features perspective. A fourth display (configural coordinate) was designed to leverage powerful perception-action skills using principles of cognitive systems engineering / ecological interface design (i.e., direct perception). Methods: An experiment was conducted to evaluate these four …

The Effect Of Cue And Target Similarity On Visual Search Response Times: Manipulation Of Basic Stimulus Characteristics, Steven Charles Fullenkamp
Browse all Theses and Dissertations
This study tested the hypothesis that the similarity of the cue and target in a visual search task is related to performance. Specifically, it was hypothesized that as the similarity between the cue and the target along the dimensions of stimulus contrast, spatial resolution and size increases, the amount of time that it takes to find a target among distractors decreases. Three experiments were performed to investigate the question. Experiments 1 and 2 employed a methodology that employed homogeneous search arrays where the contrast, spatial resolution and size of the elements were constant (high contrast, high spatial resolution and large …

Token theory (Kanter, 1977) suggests that being a token individual in an organization can cause that individual to experience discrimination, increased pressure to perform, isolation from the majority group, negative stereotyping, and can interfere with performance. The purpose of this research was to determine if varying percentages of females in a work role do indeed influence the likelihood that these negative outcomes will occur by using performance data from an applied sample. By using both supervisor ratings and objective sales figures from a sales organization, this research filled a gap in the current research, in which token theory is often …
