Impulsivity And Attention-Deficit/Hyperactivity Disorder (Adhd) Testing Competing Predictions From The Working Memory And Behavioral Inhibition Models Of Adhd, Joseph S. Raiker
Impulsivity And Attention-Deficit/Hyperactivity Disorder (Adhd) Testing Competing Predictions From The Working Memory And Behavioral Inhibition Models Of Adhd, Joseph S. Raiker
Electronic Theses and Dissertations
Impulsivity is a hallmark of two of the three DSM-IV ADHD subtypes and is associated with myriad adverse outcomes. Limited research, however, is available concerning the mechanisms and processes that contribute to impulsive responding by children with ADHD. The current study tested predictions from two competing models of ADHD – working memory (WM) and behavioral inhibition (BI) – to examine the extent to which ADHD-related impulsive responding was attributable to model-specific mechanisms and processes. Children with ADHD (n = 21) and typically developing children (n = 20) completed laboratory tasks that provided WM (domaingeneral central executive [CE], phonological/visuospatial storage/rehearsal) and …
Age-Typing Across Occupations When, Where, And Why Age-Typing Exists, Michael Dennis Reeves
Age-Typing Across Occupations When, Where, And Why Age-Typing Exists, Michael Dennis Reeves
Electronic Theses and Dissertations
The present study sought to determine the direction and degree to which occupations representative of all major occupational categories are viewed as age-typed (i.e., more appropriate for older or younger workers). The 60 occupations examined were the 12 most common and familiar occupations in each of five occupational categories used by the U.S. Census Bureau. I randomly assigned 365 participants to one of three survey conditions. Participants rated the feature centrality, proportional representation, normative age, and optimal performance age of 20 of the 60 occupations and the age-type of 20 different occupations. Results showed that participants reliably rated the occupations …
Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Electronic Theses and Dissertations
Mistakes and betrayals can cause developing interpersonal trust between parties to be broken, and damaged trust can have serious negative impacts on relationships, such as withdrawal from group interaction or the enactment of revenge. Research has suggested that the use of apologies helps to repair damaged trust. However, this research is almost exclusively based in westernized populations and has not begun to explore any cross-cultural differences. Therefore, the primary goal of this comparative cross-national laboratory study was to examine if, and how, the effectiveness of trust repair efforts differs across cultures. The effectiveness of three manipulated trust repair strategies (no …
Mixed Signals At The Intersection The Effect Of Organizational Composition On Ratings Of Black Women's Management Suitability, Laticia D. Bowens
Mixed Signals At The Intersection The Effect Of Organizational Composition On Ratings Of Black Women's Management Suitability, Laticia D. Bowens
Electronic Theses and Dissertations
Historically, Black women‘s workplace experiences have been understudied, partially due to an implicit assumption that their experiences are subsumed by research on Black men and/or White women. This oversight is even more evident in the field of management. However, considerable attention has been given to the debate about whether Black women are at a double advantage (i.e., as supposed affirmative action ―two-for-one bargains‖) or at a double disadvantage due to their double marginalizing characteristics. Empirical research in the area has found support for each side, furthering the debate, but also advancing an overly simplistic explanation for a set of experiences …
Comprehending Synthetic Speech Personal And Production Influences, Jingjing Wang-Costello
Comprehending Synthetic Speech Personal And Production Influences, Jingjing Wang-Costello
Electronic Theses and Dissertations
With the increasing prevalence of voice-production technology across societies, clear comprehension while listening to synthetic speech is an obvious goal. Common human factors influences include the listener‟s language familiarity and age. Production factors include the speaking rate and clarity. This study investigated the speaking comprehension performance of younger and older adults who learned English as their first or second language. Presentations varied by the rate of delivery in words per minute (wpm) and in two forms, synthetic or natural speech. The results showed that younger adults had significantly higher comprehension performance than older adults. English as First Language (EFL) participants …
Are We Becoming Superhuman Cyborgs? How Technomorphism Influences Our Perceptions Of The World Around Us, Heather Christina Lum
Are We Becoming Superhuman Cyborgs? How Technomorphism Influences Our Perceptions Of The World Around Us, Heather Christina Lum
Electronic Theses and Dissertations
Although traditionally researchers have focused on making robotics more user-friendly from a human perspective, a new theory has begun to take shape in which humans take on the perspective of a robotic entity. The following set of studies examined the concept of technomorphism defined as the attribution of technological characteristics to humans. This concept has been mentioned anecdotally and studied indirectly, but there is nothing currently available to tap in to the various forms that technomorphism may take. Therefore, one goal of this dissertation was to develop a scale to fill that purpose. The results of the Technomorphic Tendencies Scale …
A Configural Approach To Patient Safety Climate: The Relationship Between Climate Profile Characteristics And Patient Outcomes, Sallie J. Weaver
A Configural Approach To Patient Safety Climate: The Relationship Between Climate Profile Characteristics And Patient Outcomes, Sallie J. Weaver
Electronic Theses and Dissertations
Patient safety climate is defined as a holistic snapshot of enacted work environment practices and procedures related to patient safety, derived from shared perceptions of social and environmental work characteristics. While patient safety climate has been touted as a critical factor underlying safe patient care, our understanding of input factors influencing shared climate perceptions and, in turn, the effects of climate as a collective, group-level construct on important outcomes remains underdeveloped, both theoretically and empirically. Therefore, the current study examines (1) the antecedents that impact individual patient safety climate perceptions and (2) the relationships between hospital unit patient safety climate …
Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For Reducing Alcohol Use Among High School Students, Janani Sivasithamparam
Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For Reducing Alcohol Use Among High School Students, Janani Sivasithamparam
Electronic Theses and Dissertations
Alcohol use is the single most alarming behavior among youth in the United States. Adolescents especially are at risk for increases in heavy episodic drinking and drunkenness leading to alcohol-related problems such as academic failure, interpersonal violence, risky sexual behavior and death. In an effort to address this endemic issue, a number of alcohol use prevention programs have been developed and are currently implemented in the high school setting. Many of these programs, however, lack an empirical basis and have been unable to demonstrate significant reductions in alcohol use over time. The need for the development and dissemination of effective …

The Effectiveness Of Virtual Humans Vs. Pre-Recorded Humans In A Standardized Patient Performance Assessment, Joel Palathinkal
Electronic Theses and Dissertations
A Standardized Patient (SP) is a trained actor who portrays a particular illness to provide training to medical students and professionals. SPs primarily use written scripts and additional paper-based training for preparation of practical and board exams. Many institutions use various methods for training such as hiring preceptors for reenactment of scenarios, viewing archived videos, and computer based training. Currently, the training that is available can be enhanced to improve the level of quality of standardized patients. The following research is examining current processes in standardized patient training and investigating new methods for clinical skills education in SPs. The modality …
The Effects Of Scoring Technique On Situational Judgment Test Validity, Daniel S. Miller
The Effects Of Scoring Technique On Situational Judgment Test Validity, Daniel S. Miller
Electronic Theses and Dissertations
Situational Judgment Tests (SJTs) are frequently used by organizations as a face-valid selection measure with low adverse impact and a relatively strong relationship with relevant criteria. Despite their common use, there remain several research questions regarding the theoretical foundations and characteristics of SJTs. Additionally, developments in SJT scoring provide fertile ground for research to validate new scoring techniques to better predict criteria of interest. Motowidlo and his colleagues (2006) recently developed a scoring technique for SJTs based on the principle of Implicit Trait Policies (ITPs) which are implicit beliefs concerning the effectiveness of different behavioral choices that demonstrate varying levels …
Measuring Multilevel Constructs Theoretical And Methodological Features Of Team Behavioral Process Under Compilational Models, Toshio Murase
Measuring Multilevel Constructs Theoretical And Methodological Features Of Team Behavioral Process Under Compilational Models, Toshio Murase
Electronic Theses and Dissertations
Since at least the 1950s, researchers interested in studying the dynamics of small groups have struggled with how best to measure interaction processes. Although team process measurement issues are not particularly unique in terms of content, measuring multilevel phenomena presents an interesting problem because structural aspects are integral components of emergence. The elemental content of multilevel phenomena is wholly unique and distinguishable from the elemental content of composite units, and emerges as individual behaviors compile to higher levels of analyses. Analogous to chemical structures, behavioral phenomena manifest at higher levels in different structural patterns as members connect to one another …
Perceptual Judgment The Impact Of Image Complexity And Training Method On Category Learning, Michael T. Curtis
Perceptual Judgment The Impact Of Image Complexity And Training Method On Category Learning, Michael T. Curtis
Electronic Theses and Dissertations
The goal of this dissertation was to bridge the gap between perceptual learning theory and training application. Visual perceptual skill has been a vexing topic in training science for decades. In complex task domains, from aviation to medicine, visual perception is critical to task success. Despite this, little, if any, emphasis is dedicated to developing perceptual skills through training. Much of this may be attributed to the perceived inefficiency of perceptual training. Recent applied research in perceptual training with discrimination training, however, holds promise for improved perceptual training efficiency. As with all applied research, it is important to root application …
Examining The Impact Of Leader Social Distance On A Multicultural Team, Granados Deborah Diaz
Examining The Impact Of Leader Social Distance On A Multicultural Team, Granados Deborah Diaz
Electronic Theses and Dissertations
Leading multicultural teams is one of the main challenges faced by today’s leaders. The advantages often associated with multicultural teams (e.g., collaboration and integration of different knowledge, ideas, and approaches to a task) are often the major challenges in leading these teams. The literature on effective multicultural teams has identified leadership as an important factor for team effectiveness. Therefore, the goal of this study was to examine the effect of leader social distance in multicultural teams. A lab study was designed to test the impact of experimentally-manipulated leader social distance (socially close or socially distant) on the relationship between team …
The Relationship Between Course Syllabi And Participant Evaluation Reactions Across Web-Based And Face-To-Face Courses, David Richard Glerum
The Relationship Between Course Syllabi And Participant Evaluation Reactions Across Web-Based And Face-To-Face Courses, David Richard Glerum
Electronic Theses and Dissertations
A common form of training or education evaluation involves the examination of course participant reactions towards various aspects of the course for summative evaluation purposes. Participant reactions have been examined within the framework of a comparison between online and face to face courses often with a slight positive weight towards online courses (Sitzmann et al., 2006). Past research on this topic has denoted a need for studies examining the relationship between objective course characteristics and participant reactions. This paper seeks to examine the relationship between participant reactions of a sample of geographically disbursed teachers enrolled in a large, national professional …

Bleeding Control Using Multiple Amputee Trauma Trainer In Medical Simulation Comparison Of Movement Versus Non-Movement In Training, Christine M. Allen
Electronic Theses and Dissertations
Army first responders, specifically Combat Medics and Combat Lifesavers, provide medical intervention while in the field. Didactic as well as hands-on training helps to prepare these first responders, and one module they receive involves bleeding control. First responders are taught to use the Combat Application Tourniquet® (CAT® ) to stop bleeding from limbs subjected to severe injury such as amputation, gunshot, or severe lacerations. A training aid like the Multiple Amputee Trauma Trainer™ (MATT™) simulator provides tourniquet training using a lifelike bilateral lower limb amputee. In addition, MATT™ combines movement and resistance while the first responder applies the tourniquet, mimicking …
An Investigation Of The Relationships Between Motivation, Worker Role Conflicts And Worker Outcomes, Robert C. Kennedy
An Investigation Of The Relationships Between Motivation, Worker Role Conflicts And Worker Outcomes, Robert C. Kennedy
Electronic Theses and Dissertations
This study investigated the relationships between several work motivational process variables and work-life-conflict (WLC) and how these variables contribute to job related outcomes such as work performance, job satisfaction and life satisfaction. This survey study identified several correlations which suggest that a more comprehensive model of motivation should include variables such as energy pool and direction toward organizational objectives. Results also suggest that WLC contributes to the amount of energy pool available to workers and the amount of motivation exhibited by workers. WLC also impacts important job and life attitudes directly and through the above mentioned motivation process variables. The …
The Use Of Video Game Achievements To Enhance Player Performance, Self-Efficacy, And Motivation, Lucas Blair
The Use Of Video Game Achievements To Enhance Player Performance, Self-Efficacy, And Motivation, Lucas Blair
Electronic Theses and Dissertations
A taxonomy of achievement design features that exist currently in video game systems was created in order to evaluate the current the state of the art in achievement design. From the taxonomy of design features multiple mechanisms of action that influence player behavior were identified. These mechanisms lead to a predictive model that can guide the designs of achievements in order to improve performance, self-efficacy and motivation in players. Expected, unexpected, and incremental achievements were tested. Notifications occurring before and after earning an achievement were also tested. In addition to testing individual mechanisms of action a “combined achievement” was created …

The Effects Of Presentation Mode And Pace On Learning Immunology With Computer Simulation A Cognitive Evaluation Of A Multimedia Learning Resource, Radakovich Kristy Bradley
Electronic Theses and Dissertations
Multimedia learning tools have the potential to benefit instructors and learners as supplemental learning materials. However, when such tools are designed inappropriately, this can increase cognitive taxation and impede learning, rendering the tools ineffective. Guided by the theoretical underpinnings provided by cognitive load theory and the cognitive theory of multimedia learning, this study sought to empirically evaluate the effectiveness of a multimedia simulation tool aimed at teaching immunology to novices in an instructional setting. The instructional mode and pace of the tool were manipulated, the three levels of each variable yielding nine experimental groups. The effects of mode and pace …
Modeling Transport And Protein Adsorption In Microfluidic Systems, Craig Finch
Modeling Transport And Protein Adsorption In Microfluidic Systems, Craig Finch
Electronic Theses and Dissertations
Mass transport limitations and surface interactions are important phenomena in microfluidic devices. The flow of water is laminar at small scales and the absence of turbulent mixing can lead to transport limitations, especially for reactions that take place at surfaces. Microscale devices have a high ratio of surface area to volume, and proteins are known to adsorb preferentially at interfaces. Protein adsorption plays a significant role in biology by mediating critical processes such as the attachment of cells to surfaces, the immune response and the coagulation of blood. Simulation tools that can quantitatively predict transport and protein adsorption will enable …

Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler
Electronic Theses and Dissertations
This dissertation investigated the impact of active stereoscopic 3-dimensional (3D) imagery equipment and individual differences in visuo-spatial working memory (VSWM) capacity on retention of a set of similar, novel objects (i.e., armored military vehicles). Seventy-one participants were assessed on their visuo-spatial working memory using the Visual Patterns Test (Della Sala, Gray, Baddeley, & Wilson, 1997). They were then assigned to one of four different conditions (3D high VSWM, 3D low VSWM, 2D high VSWM, 2D low VSWM) based upon their visuo-spatial working memory. Participants were then trained to identify military vehicles using a simulation that presented the training stimuli in …
A Comparison Of Paper-Pencil Versus Video-Conferencing Administration Of A Neurobehavioral Screening Test, Tyler Cole Duffield
A Comparison Of Paper-Pencil Versus Video-Conferencing Administration Of A Neurobehavioral Screening Test, Tyler Cole Duffield
Electronic Theses and Dissertations
Regardless of the reason, many patients/clients do not have access to face-to-face medical, neuropsychological, or mental health consultation, assessment, or treatment (Cowain, 2001). The term Remote Neuropsychological Assessment (RNA) has been proposed by Browndyke to denote the general use of telecommunication and Internet-based technologies in neuropsychological assessment and practice (as cited in Schatz & Browndyke, 2002). RNA (Telemedicine) offers a plausible, potentially cost-effective solution to individuals in need of medical, neuropsychological, or mental health consultation, assessment, or treatment that are located in geographical areas away from the specialist (Armstrong, 2006; Berman, 2005; Cowain, 2001; Jacobsen, Sprenger, Andersson, & Krogstad, 2003). …
Healthy Aging And Self-Objectification The Impact Of Empowerment And Feminist Attitudes On Body Image, Eating Behavior, And Aging Satisfaction, Karen P. Grippo
Healthy Aging And Self-Objectification The Impact Of Empowerment And Feminist Attitudes On Body Image, Eating Behavior, And Aging Satisfaction, Karen P. Grippo
Electronic Theses and Dissertations
The purpose of this study was to contribute to women’s healthy aging across the adult lifespan by empirically examining potential protective factors (e.g., empowerment and feminist attitudes) in maintaining positive body image, healthy eating behavior, and aging satisfaction. Objectification Theory (Fredrickson & Roberts, 1997) provided a theoretical framework for understanding the connections between sexual-objectification experiences, media influences, and self-objectification, and the resulting negative psychological consequences for women in Western society. This study was the first to examine empowerment in relation to Objectification Theory. Additionally, a developmental perspective was gained by using a diverse sample of young, middle-aged, and older women …
Investigating The Optimal Presentation Of Feedback In Simulation-Based Training An Application Of The Cognitive Theory Of Multimedia Learning, Wendi Van Buskirk
Investigating The Optimal Presentation Of Feedback In Simulation-Based Training An Application Of The Cognitive Theory Of Multimedia Learning, Wendi Van Buskirk
Electronic Theses and Dissertations
There are many different training interventions that can be used in simulation based training systems (e.g., cueing, hinting, highlighting, deliberate practice, etc.). However, the most widely used training intervention in the military is feedback, most often presented in the form of a debrief. With advances in technology, it is possible to measure and diagnose performance in real-time. Thus it is possible to provide immediate feedback during scenarios. However, training systems designers should not consider the timing of feedback in isolation. There are other parameters of feedback that must also be considered which may have an impact on performance. Specifically, feedback …
