Temperament And Child Maltreatment: A Closer Look At The Interactions Among Mother And Child Temperament, Stress And Coping, Emotional And Behavioral Regulation, And Child Maltreatment Potential, Amanda Lowell
Electronic Theses and Dissertations
Several theoretical risk models were proposed previously regarding the prediction of child maltreatment. Although child maltreatment was predicted individually in these models by such variables as parent temperament, emotional and behavioral regulation, stress, coping, and child temperament, these variables were not yet examined collectively. As such, a new transactional theory was proposed for the current study. As part of this study, a national community sample of 158 culturally diverse mothers of young children who were between the ages of 1½- to 5-years rated their own temperament, emotional and behavioral regulation abilities, parenting stress, daily hassles, and coping behaviors as well …
Comparing Types Of Adaptive Automation Within A Multi-Tasking Environment, Grant S. Taylor
Comparing Types Of Adaptive Automation Within A Multi-Tasking Environment, Grant S. Taylor
Electronic Theses and Dissertations
Throughout the many years of research examining the various effects of automation on operator performance, stress, workload, etc., the focus has traditionally been on the level of automation, and the invocation methods used to alter it. The goal of the current study is to instead examine the utilization of various types of automation with the goal of better meeting the operator’s cognitive needs, thus improving their performance, workload, and stress. The task, control of a simulated unmanned robotic system, is designed to specifically stress the operator’s visual perception capabilities to a greater degree. Two types of automation are implemented to …
Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson
Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson
Electronic Theses and Dissertations
Few studies exist examining the relationship between self-reported stress and cognitive function in healthy nonpsychiatric older adults, and even less studies have examined whether high levels of self-reported stress accelerate the cognitive decline found in normal late-aging populations. A group of older nonpsychiatric adults, ages 54 years and above, were asked to complete three measures assessing their self-perceived stress over the past month, past year, and their lifetime. Sixty-one adults between the ages of 54 and 88 (52% female) participated in a second phase in which neuropsychological tasks were administered to assess three cognitive domains; memory, learning, and executive functioning. …
Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem
Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem
Electronic Theses and Dissertations
In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …
Adolescents' Stress And Health: Parental Influences And Cognitive Mediators, Reesa Donnelly
Adolescents' Stress And Health: Parental Influences And Cognitive Mediators, Reesa Donnelly
Electronic Theses and Dissertations
Research to date indicates that parental and cognitive variables play a role in stress responses and health outcomes. Although researchers are beginning to focus on developmental processes in stress/health outcomes, there is little research examining which parental behaviors are most predictive of stress/health and whether cognitive variables mediate this relationship. As a result, the current study examines the self-reports of 160 late adolescents regarding parental behaviors, cognitive variables, and stress/health outcomes. In addition, blood pressure reactivity to a stressful situation was collected as a physiological measure of stress. The results suggest that, among the parental behaviors that are examined, parental …
Locus Of Control And Self-Efficacy: Potential Mediators Of Stress, Illness, And Utilization Of Health Services In College Studen, Angela Roddenberry
Locus Of Control And Self-Efficacy: Potential Mediators Of Stress, Illness, And Utilization Of Health Services In College Studen, Angela Roddenberry
Electronic Theses and Dissertations
Stress has been linked to increased illness in several biologically based studies. In contrast, only a limited number of studies have assessed psychological variables related to stress, with self-efficacy and locus of control serving as potentially important variables. Thus, the current study investigated the mediating effects of self-efficacy and locus of control in the relationship between stress, psychological and physical symptoms, and the utilization of health services in college students. Results suggested that stress was correlated positively with symptoms. External locus of control was correlated positively with stress and symptoms, and self-efficacy was correlated negatively with stress and symptoms. Further, …
The Relationship Between Self-Reported Chronic Stress And Divided Attention Performance, Diane Petrac
The Relationship Between Self-Reported Chronic Stress And Divided Attention Performance, Diane Petrac
Electronic Theses and Dissertations
While previous research has extensively examined the effect of acute stress on cognitive performance, relatively little research has explored the relationship between chronic stress and cognitive performance. The current study aimed to control for current state anxiety to better isolate more chronic stress, when examining the relationship with performance on divided attention tasks. Fifty-four university undergraduates, who self-reported a wide range of perceived chronic stress (10-item Perceived Stress Scale), completed the Trail-Making Test and a dual (auditory and visual) Continuous Performance Test (CPT). Hierarchical regressions were performed to explore cognitive predictors of chronic perceived stress. After covarying for state anxiety …
The Relation Between Optimism And Job Performance: An Applied Setting, Mary Davis
The Relation Between Optimism And Job Performance: An Applied Setting, Mary Davis
Electronic Theses and Dissertations
Research on cognitive ability measures consistently concludes that they are predictive of employee performance. While accounting for only about 9% of the variance in performance, however, cognitive ability measures are not sufficient. Alternative measures, such as measures of personality constructs, must be included to fully predict employee performance. The research on personality measures suggests that they are marginally predictive of employee performance. Research also suggests that predicative accuracy of personality measures can be enhanced when the measure is specific to the situation (i.e., stress measure are more predictive of performance in high stress situations compared to moderate or low stress …
Perceived Stress, Coping, And Adequacy Of Social Support: Implications For Subjective Well-Being In College Students, Kia Asberg
Electronic Theses and Dissertations
Stress is a widespread concept commonly associated with psychological and medical problems that may impair an individual's functioning and incur costs on society. Alarming rates of depression, anxiety, suicidal ideation, and other stress-related problems have been found among college students. This study (N = 241)argues that reducing emotional and financial stress-related costs may be possible through increasing public and professional awareness of moderating variables, such as social support and coping resources. Results indicated that stress, inadequate social support, and escape-avoidance coping were related to higher levels of depression and lower life satisfaction in both males and females. Social support functioned …
Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich
Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich
Electronic Theses and Dissertations
This study investigated the effects of cross-modality warning presentation and retention in a dual-task paradigm in a simulated military environment under various task-induced stress levels. It was also intended to determine what role working memory played in the mode of warning presentation that resulted in the highest retention and subsequent compliance. An all within participant design was created in order to determine if scores on working memory span tasks predicted performance across the varying forms of warning presentation. Furthermore, task-induced stress levels were varied over the course of the experiment to identify if workload transitions affected performance. Results revealed that …
Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris
Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris
Electronic Theses and Dissertations
Recent stressful environments within military and non-military domains are producing a new challenge for the lab-based study of stress on task performance, one that requires knowledge of underlying cognitive-motivational and goal orientation factors. Results of recent stress on task performance research traditionally employ metaphorical explanations (i.e., resource theory) in order to rapidly apply stimulus-response outcomes to the real world counterparts. This dissertation provides an alternative perspective about these metaphorical, or black box, interpretations and reveals how they may be confounded with respect to the intended real world counterpart. To examine how voluntary human control can influence traditional stress/no-stress research findings, …
