Predicting Child Maltreatment Potential In Mothers Who Are Substance-Involved: A Study Of Childhood Adversity, Stress, Affectivity, Emotion Dysregulation, And Emotion Regulation Strategies As Mechanisms Of Action, Amanda Lowell
Electronic Theses and Dissertations
Compared to the general population, parents who are substance-involved are both more likely to have experienced adversity during childhood and to exhibit elevated child maltreatment potential later in life. Within this population, mothers with young children are particularly at-risk. In order to enhance scientific understanding of this phenomenon, this study identified and examined several characteristics that were shown previously to be related to substance misuse and to the experience and perpetration of maltreatment. These characteristics included stress, affectivity, emotion dysregulation, and emotion regulation strategies. The current study examined these variables collectively in order to clarify the mechanisms at play in …
Examining The Role Of Cardiovascular And Cognitive Fitness In Goal-Directed Aiming Across The Lifespan, Michael Rupp
Examining The Role Of Cardiovascular And Cognitive Fitness In Goal-Directed Aiming Across The Lifespan, Michael Rupp
Electronic Theses and Dissertations
Older adults experience more difficulties completing goal directed movements than younger adults. The reasons for this have not been completely elucidated within the research literature; however, it is thought that age related movement differences are due to at least one of three possible reasons. The current study investigated the influence of these three hypotheses: (1) biomechanical changes (limbs, joints, or muscles), (2) sensory feedback processing ability, or (3) differences in overall movement strategy on movement kinematics. Additionally, physical activi-ty is known to improve both physical and cognitive functioning and staying cognitively active may also attenuate age-related declines in cognitive ability; …
The Role Of Accounts And Apologies In Mitigating Blame Toward Human And Machine Agents, Kimberly Stowers
The Role Of Accounts And Apologies In Mitigating Blame Toward Human And Machine Agents, Kimberly Stowers
Electronic Theses and Dissertations
Would you trust a machine to make life-or-death decisions about your health and safety? Machines today are capable of achieving much more than they could 30 years ago—and the same will be said for machines that exist 30 years from now. The rise of intelligence in machines has resulted in humans entrusting them with ever-increasing responsibility. With this has arisen the question of whether machines should be given equal responsibility to humans—or if humans will ever perceive machines as being accountable for such responsibility. For example, if an intelligent machine accidentally harms a person, should it be blamed for its …
Using Exposure Therapy To Treat People Who Stutter: A Multiple Baseline Design, Jennifer Scheurich
Using Exposure Therapy To Treat People Who Stutter: A Multiple Baseline Design, Jennifer Scheurich
Electronic Theses and Dissertations
Social anxiety disorder (SAD) is a debilitating condition, and it is estimated that approximately half of adults who stutter have SAD. Thus, there is a need for the assessment and treatment of SAD in this population. Cognitive-behavioral therapy (CBT) has shown promise in decreasing anxiety symptoms among adults who stutter and have SAD, but exposure, the key ingredient for successful CBT for SAD, has been understudied and underemphasized. The aims of this study were to develop an exposure therapy protocol specifically for people who stutter and have SAD and to evaluate its efficacy for reducing anxiety and stuttering severity. Utilizing …
How Does Brief Cognitive Behavioral Therapy Work? Potential Mechanisms Of Action For Veterans With Physical And Psychological Comorbidities, Frances Deavers
How Does Brief Cognitive Behavioral Therapy Work? Potential Mechanisms Of Action For Veterans With Physical And Psychological Comorbidities, Frances Deavers
Electronic Theses and Dissertations
Depression and anxiety are commonly comorbid among patients with chronic medical conditions. These comorbidities are associated with negative outcomes including poorer quality of life and worse physical functioning. Evidence that traditional cognitive behavioral therapy (CBT) is less effective for these populations has led to the development of brief CBT protocols that incorporate physical health self-management skills and are delivered in primary care. To continue refining treatment packages, it is important to understand how brief CBT works. The present study used the transactional model of stress and coping as a framework for investigating potential mechanisms of action of brief CBT. Veterans …
Inattentive Behavior In Boys With Adhd During Classroom Instruction: The Mediating Role Of Working Memory Processes, Sarah Orban
Inattentive Behavior In Boys With Adhd During Classroom Instruction: The Mediating Role Of Working Memory Processes, Sarah Orban
Electronic Theses and Dissertations
Children with ADHD exhibit clinically impairing inattentive behavior during classroom instruction and other cognitively demanding contexts. However, there have been surprisingly few attempts to validate anecdotal parent/teacher reports of intact sustained attention during 'preferred' activities such as watching movies. The current investigation addresses this omission, and provides an initial test of how ADHD-related working memory deficits contribute to inattentive behavior during classroom instruction. Boys ages 8-12 (M=9.62, SD=1.22) with ADHD (n=32) and typically developing children (TD; n=30) completed a counterbalanced series of working memory tests and two videos on separate assessment days: an analogue math instructional video, and a non-instructional …
Getting The Work Out Of Workouts: Evaluating The Effectiveness And Outcomes Of A Physical Exercise Motivational Intervention For Older Workers, Brandon Sholar
Getting The Work Out Of Workouts: Evaluating The Effectiveness And Outcomes Of A Physical Exercise Motivational Intervention For Older Workers, Brandon Sholar
Electronic Theses and Dissertations
To mitigate their estimated $300 billion in annual health-related losses, many companies have instituted workplace wellness initiatives designed to promote physical activity among their employees, improving the overall health of their workforce. Though middle-aged and older workers may potentially enjoy the greatest physical, stress and cognitive benefits from regular exercise, workplace wellness programs have been less successful in attracting such employees. This study developed and tested a 6-week exercise motivation intervention designed to meet the needs of sedentary, older working adults and to determine what non-physical benefits might result from increased levels of physical exercise. The intervention, based primarily on …
Applied Problem Solving In Children With Adhd: The Mediating Roles Of Working Memory And Mathematical Calculation, Lauren Friedman
Applied Problem Solving In Children With Adhd: The Mediating Roles Of Working Memory And Mathematical Calculation, Lauren Friedman
Electronic Theses and Dissertations
The difficulties children with ADHD experience solving applied math problems (i.e., word problems) are well documented; however, the independent and/or interactive contribution of cognitive processes underlying these difficulties is not fully understood and warrant scrutiny. The current study examines two primary cognitive processes integral to children's ability to solve applied math problems: working memory (WM) and math calculation ability (i.e., the ability to utilize specific facts, skills, or processes related to basic math operations stored in long-term memory). Thirty-six boys with ADHD-combined presentation and 33 typically developing (TD) boys aged 8-12 years old were administered multiple counterbalanced tasks to assess …
Leadership And Subordinate Engagement: A Meta-Analytic Examination Of Its Mechanisms Using Self-Determination Theory, Henry Young
Leadership And Subordinate Engagement: A Meta-Analytic Examination Of Its Mechanisms Using Self-Determination Theory, Henry Young
Electronic Theses and Dissertations
Although past research has suggested ineffective leadership to be the most common reason for low levels of employee engagement, little is known about the mediating mechanisms underlying this relationship. To address this gap in research, I tested a theoretical model based on Self-Determination Theory (SDT; Deci & Ryan, 2000) in which two focal mechanisms, leader-member exchange (LMX) and empowerment, functioned in sequential order to predict the relationship between Full Range Leadership and subordinate engagement. Results showed that transactional leadership had positive and negative indirect effects on engagement, suggesting that transactional leadership comprises a "double-edged sword" as a predictor of subordinate …
Beyond Compliance: Examining The Role Of Motivation In Vigilance Performance, Alexis Neigel
Beyond Compliance: Examining The Role Of Motivation In Vigilance Performance, Alexis Neigel
Electronic Theses and Dissertations
Vigilance, or sustained attention, is the capacity to attend to information for a prolonged period of time (Davies & Parasuraman, 1982; Jerison, 1970; Warm, 1977). Due to limitations of the human nervous system, as well as the environmental context, attention can begin to wane over time. This results in a phenomenon referred to as the vigilance decrement, or a decline in vigilance performance as a function of time. The vigilance decrement can manifest as poorer attention and is thusly associated with poor performance, which is defined behaviorally as more lapses in the detection of critical signals and an increase in …
Do Multiple Conditions Elicit The Visual Redundant Signals Effect In Simple Response Times?, Ada Mishler
Do Multiple Conditions Elicit The Visual Redundant Signals Effect In Simple Response Times?, Ada Mishler
Electronic Theses and Dissertations
The redundant signals effect, or redundancy gain, is an increase in human processing efficiency when target redundancy is introduced into a display. An advantage for two visual signals over one has been found in a wide variety of speeded response time tasks, but does not always occur and may be weakened by some task parameters. These disparate results suggest that visual redundancy gain is not a unitary effect, but is instead based on different underlying mechanisms in different tasks. The current study synthesizes previous theories applied to redundancy gain into the three-conditions hypothesis, which states that visual redundancy gain depends …
Theory And Measurement Of Perceived Introvert Mistreatment, Mallory Mccord
Theory And Measurement Of Perceived Introvert Mistreatment, Mallory Mccord
Electronic Theses and Dissertations
Perceived introvert mistreatment, or the extent to which an individual perceives he or she is treated unfairly at work because he or she is introverted, is a form of workplace mistreatment that may be associated with numerous negative outcomes for the workers it impacts. Although an understanding of perceived introvert mistreatment may augment current theoretical knowledge of workplace mistreatment, researchers have yet to consider why (or if) this mistreatment exists or the effects it may have on the individual. Thus, the purpose of this paper is twofold: first, in an attempt to explain how perceived introvert mistreatment may develop and …
Identification Of Areas Of Patient Need Using The Cancer Support Source Program, Emily Ross
Identification Of Areas Of Patient Need Using The Cancer Support Source Program, Emily Ross
Electronic Theses and Dissertations
Understanding, screening, and providing resources for quality of life factors and psychosocial distress have become an important area of focus in cancer care. Negative consequences of poor quality of life and psychosocial distress have been widely studied in oncological research. The National Comprehensive Cancer Network, or NCCN, defines "psychosocial distress" as extending on a continuum, "ranging from common normal feelings of vulnerability, sadness, and fears to problems that can become disabling, such as depression, anxiety, panic, social isolation, and existential and spiritual crisis" ("National Comprehensive Cancer Network," n.d.). Findings have indicated the significant impact of poor quality of life and …
Not Woman Enough Harassment: Scale Development And An Integrated Model From Antecedent To Outcome, Amanda Wolcott
Not Woman Enough Harassment: Scale Development And An Integrated Model From Antecedent To Outcome, Amanda Wolcott
Electronic Theses and Dissertations
The rise of research on workplace mistreatment in the past twenty years can be attributed to the realization that workplace mistreatment is associated with a host of deleterious outcomes for both the individual targets of the mistreatment and the organizations in which they work. However, the extant literature is failing to capture the full range of sex-based mistreatment that people may experience through a tendency to focus solely on sexual harassment and sex discrimination, which are very specific types of behavior based on one's sex and gender stereotypes. In this dissertation, I introduce the construct of Not Woman Enough Harassment, …
Affective Chickens And Performance Eggs: A Longitudinal Meta-Analysis, Matthew Lapalme
Affective Chickens And Performance Eggs: A Longitudinal Meta-Analysis, Matthew Lapalme
Electronic Theses and Dissertations
The affective revolution in the organizational sciences has yielded a body of theoretical and empirical research examining the relationship between affect and performance. This work has typically advanced affect as a predictor of performance; however, more recent theory suggests that the relationship between affect and performance is reciprocal. Since little empirical work exists supporting reciprocity between affect and performance, the purpose of this dissertation is to test if affect and performance are actually reciprocally related. Importantly, the advent of longitudinal and experiential research designs in the organizational sciences affords empirical opportunities to test such theory. This dissertation examines the temporal …
Posttraumatic Stress Disorder Or Combat Experience? A Functional Near-Infrared Spectroscopy Study Of Trauma-Related Auditory And Olfactory Cues, Michael Gramlich
Posttraumatic Stress Disorder Or Combat Experience? A Functional Near-Infrared Spectroscopy Study Of Trauma-Related Auditory And Olfactory Cues, Michael Gramlich
Electronic Theses and Dissertations
While the clinical communities are aware of the prevalence of posttraumatic stress disorder (PTSD) among OEF/OIF/OND veterans, further efforts are necessary to bolster comprehensive strategies for assessment and treatment. The purpose of this study was to investigate whether a combat-related PTSD symptom provocation paradigm would elicit unique neurological responses via functional near-infrared spectroscopy across three groups – combat veterans with PTSD, combat veterans without PTSD, and nonmilitary participants without PTSD. Results indicated that combat veterans with PTSD demonstrated significant activation during exposure to a trauma-related sound compared to nonmilitary personnel at channels 14 (d = 1.03) and 15 (d = …
An Exploration Of The Feasibility Of Functional Near-Infrared Spectroscopy As A Neurofeedback Cueing System For The Mitigation Of The Vigilance Decrement, Gabriella Hancock
An Exploration Of The Feasibility Of Functional Near-Infrared Spectroscopy As A Neurofeedback Cueing System For The Mitigation Of The Vigilance Decrement, Gabriella Hancock
Electronic Theses and Dissertations
Vigilance is the capacity for observers to maintain attention over extended periods of time, and has most often been operationalized as the ability to detect rare and critical signals (Davies & Parasuraman, 1982; Parasuraman, 1979; Warm, 1984). Humans, however, have natural physical and cognitive limitations that preclude successful long-term vigilance performance and consequently, without some means of assistance, failures in operator vigilance are likely to occur. Such a decline in monitoring performance over time has been a robust finding in vigilance experiments for decades and has been called the vigilance decrement function (Davies & Parasuraman, 1982; Mackworth, 1948). One of …
Cognitive Flexibility: Using Mental Simulation To Improve Script Adaptation, Javier Rivera
Cognitive Flexibility: Using Mental Simulation To Improve Script Adaptation, Javier Rivera
Electronic Theses and Dissertations
Human behavior and decision-making depend largely on past experiences that generate specific action patterns (i.e., scripts, Gioia & Manz, 1985) for specific situations. In an ideal world, in which changes in the environment do not conflict with these action patterns, humans would be able to operate consistently, efficiently, and automatically. However, real-world environments are dynamic and fluid, thus altering behavior and forcing changes in scripts. Research suggests that to implement alternate solutions to changing situations, humans select from a "library" of learned scripts. Since humans tend to implement scripts to the degree that these are successful over a period of …
The Effects Of Tactile Displays On The Perception Of Target Distance, Timothy White
The Effects Of Tactile Displays On The Perception Of Target Distance, Timothy White
Electronic Theses and Dissertations
Because vital information can be missed by Soldiers in combat environments that tax the eyes and the ears, it is imperative that alternative techniques be investigated to determine their potential in relaying this information in an effective way. This research investigated the use of a tactile display for providing distance and azimuth information about enemy targets. In a series of three experiments, participants were asked to engage enemy targets while utilizing cues that provided location information. In Experiment 1, two tactile cueing techniques (i.e., varying intensity and varying pulse rate) and three auditory cueing techniques (i.e., non-spatial speech, varying frequency …
Visual Scanpath Training For Facial Affect Recognition In A Psychiatric Sample, Chi Chan
Visual Scanpath Training For Facial Affect Recognition In A Psychiatric Sample, Chi Chan
Electronic Theses and Dissertations
Social cognition is essential for functional outcome and quality of life in psychiatric patients. Facial affect recognition (FAR), a domain of social cognition, is impaired in many patients with schizophrenia and bipolar disorder. There is evidence that abnormal visual scanpath patterns may underlie FAR deficits, and metacognitive factors may impact task performance. The present study aimed to develop a brief, individually-administered, computerized training program to normalize scanpath patterns in order to improve FAR in patient with a psychosis history or bipolar I disorder. The program was developed using scanpath data from 19 nonpsychiatric controls (NC) while they completed a FAR …
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Electronic Theses and Dissertations
Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …
Optimizing Strategies For In Vivo Exposure In The Traditional Clinical Setting, Maryann Owens
Optimizing Strategies For In Vivo Exposure In The Traditional Clinical Setting, Maryann Owens
Electronic Theses and Dissertations
This study examined the ability of a pre-recorded videoconferencing (VC) audience to elicit the physiological and subjective arousal associated with Social Anxiety Disorder (SAD) when giving a formal presentation. This study had three objectives: (a) to determine whether speaking to the VC audience elicited significant increases in physiological response (e.g., heart rate and electrodermal activity) and subjective distress over baseline resting conditions (b) to determine whether the VC task more closely replicates the physiological and subjective experience of giving a speech to a comparable real-life audience than levels elicited by a Virtual Reality (VR) environment and (c) to determine whether …
Reading Comprehension Deficits In Children With Adhd: The Mediating Roles Of Working Memory And Orthographic Conversion, Lauren Friedman
Reading Comprehension Deficits In Children With Adhd: The Mediating Roles Of Working Memory And Orthographic Conversion, Lauren Friedman
Electronic Theses and Dissertations
Reading comprehension deficits in children with ADHD are well-established; however, limited information exists concerning the cognitive mechanisms that contribute to these deficits and the extent to which they interact with one another. The current study examines two broad cognitive processes known to be involved in children's reading comprehension abilities—(a) working memory (i.e., central executive processes [CE], phonological short-term memory [PH STM], and visuospatial short-term memory [VS STM]) and (b) orthographic conversion—to elucidate their unique and interactive contribution to ADHD-related reading comprehension deficits. Thirty-one children with ADHD and 30 typically developing (TD) children aged 8 to 12 years (M = 9.64, …
Childhood Trauma, Reflective Functioning And Attributions, Self-Efficacy, And Perceived Parenting Competence: What Happens When The Traumatized Child Grows Up And Becomes A Mother?, Annelise Cunningham
Childhood Trauma, Reflective Functioning And Attributions, Self-Efficacy, And Perceived Parenting Competence: What Happens When The Traumatized Child Grows Up And Becomes A Mother?, Annelise Cunningham
Electronic Theses and Dissertations
Previous research documented the relationship between self-efficacy and perceived parenting competence. Further, previous evidence supported the cognitive, emotional, and behavioral consequences of early exposure to trauma. To build on these previously noted relationships, the present study examined the relationships among reflective functioning and attributions, self-efficacy, and perceived parenting competence, with self-efficacy serving as a mediating variable. Specifically, this study sought to focus on the cognitive variables associated with mothers' perceived self-efficacy and parenting competence and how those variables interact differently when early exposure to trauma is present. As part of this study, a national community sample of 126 culturally diverse …
Supporting Situation Awareness Through Robot-To-Human Information Exchanges Under Conditions Of Visuospatial Perspective Taking, Elizabeth Phillips
Supporting Situation Awareness Through Robot-To-Human Information Exchanges Under Conditions Of Visuospatial Perspective Taking, Elizabeth Phillips
Electronic Theses and Dissertations
The future vision of military Soldier—robot teams is one in which Soldiers and robots work together to complete separate, but interdependent tasks that advance the goals of the mission. However, in the near term, robots will be limited in their ability to successfully perform tasks without, at least, occasional assistance from their human teammates. A need exists to design, in robots, mechanisms that can support human situation awareness (SA) regarding the operations of the robot, which humans can use to provide interventions in robot tasks. The purpose of the current study was to test the effects of information exchanges provided …
Psychometric Properties Of A Social Skills Assessment Using Virtual Environment, Thien-An Le
Psychometric Properties Of A Social Skills Assessment Using Virtual Environment, Thien-An Le
Electronic Theses and Dissertations
Background: Social Anxiety Disorder (SAD) is a marked and persistent fear of social and/or performance situations in which embarrassment or scrutiny from others may occur. In children, this marked and persistent fear must be present in peer settings and is not exclusive to interactions with adults (American Psychiatric Association [APA], 2013). Behaviorally, children with SAD may avoid eye contact and exhibit other behavioral symptoms such as stooped shoulders, nail biting, trembling voice, avoidance of social and performance situations, muffled voice, longer speech latency, inappropriate tone or low voice volume, and lack of spontaneous speech (Beidel & Turner, 2007; Ollendick, Benoit, …
The Attitude-Engagement Model Within-Persons: An Experience Sampling Study Of Job Attitudes And Behavioral Engagement, David Glerum
The Attitude-Engagement Model Within-Persons: An Experience Sampling Study Of Job Attitudes And Behavioral Engagement, David Glerum
Electronic Theses and Dissertations
Although a large body of research has attempted to answer the question, "Is a happy worker a more productive worker?" by examining the relationship between job attitudes and behaviors, results are often inconsistent. Drawing upon Fishbein and Ajzen's (1974) compatibility principle as well as theory on job attitude change and dynamic performance, the current study sought to answer this question by examining the attitudes-performance relationship at the within-persons level of analysis. Specifically, an Attitude-Engagement Model that specifies a broad conceptualization of job attitudes and behavioral engagement should exhibit the strongest relationship between job attitudes and job behaviors (Harrison, Newman, & …
Weight Discrimination Through Social Networking Sites: The Moderating Effects Of Gender, Stereotype-Consistent Behavior, And Occupational Setting, Bridget Mchugh
Electronic Theses and Dissertations
As the use of social networking sites (SNSs) in hiring increases, human resources professionals have become concerned with the increased probability of discriminatory hiring decisions. At the same time, there is increasing evidence that discrimination towards overweight and obese applicants has risen in the past decade. The present study addressed these concerns by examining the impact of an applicant's weight in a SNS profile picture on the decision to hire the applicant for a sales position. The impact of the applicant's gender, body mass index, and stereotype-consistent behaviors on hiring intentions were examined. In addition, the type of sales position …
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
Electronic Theses and Dissertations
Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …
Investigating The Influence Of The Built Environment On Energy-Saving Behaviors, Brittany Sellers
Investigating The Influence Of The Built Environment On Energy-Saving Behaviors, Brittany Sellers
Electronic Theses and Dissertations
This dissertation addresses a gap in the existing sustainability behavior research, by integrating research from the social sciences about environmental attitudes and knowledge with approaches from engineering regarding the characteristics of the built environment. Specifically, this dissertation explores the role of both environmental knowledge and design features within the built environment on building occupants' energy behaviors throughout the course of an environmental conservation campaign. Data were collected from 240 dormitory residents using a multi-phase questionnaire approach to study these factors and their combined impact within the context of environmental sustainability practices on UCF's campus. The results from a series of …
