Gene-Environment Interactions In Attention Deficit Hyperactivity Disorder, Holly Donovan Barnard

Electronic Theses and Dissertations

The overall goal of this project is to advance our understanding of the multifactorial etiology of Attention Deficit Hyperactivity Disorder (ADHD) by testing a diathesis-stress model of gene x environment (g x e) interactions. Although the literature increasingly supports g x e interactions in the manifestation of ADHD, few studies have investigated multiple genetic and environmental risk factors, included direct tests of gene - environment correlations (rG-Es), explored the specificity of interactions to symptom dimensions, or attempted to minimize comparisons. Therefore, utilizing both within-family (FBAT/PBAT) and case-control methodology, this study sought to (1) explore main effects of polymorphisms in the …

Still Standing, Wendy Joy Rosoff

Electronic Theses and Dissertations

On April 20, 1999 Eric Harris and Dylan Klebold walked into Columbine High School and killed 12 students and 1 teacher. The days following the shooting were spent questioning their motive and it seems, to this day, some are still confused. If those in charge of the investigation would have stopped pointing fingers and listened to the cries of the shooters and the students, they would see that Columbine was a time bomb. Students tells stories of bullying and torment and many agree that a group of athletes dominated the school.

Most who see bullying see it as entertaining, but …

Peer And Maternal Relationship Predictors Of Adolescent Romantic Conflict Resolution, Pallavi Visvanathan

Electronic Theses and Dissertations

The objective of the current study was to examine whether change in adolescent conflict resolution in romantic relationships is predicted by adolescents' prior interactions with mothers and friends. A community sample of 191 adolescents (96 female), representative of the U.S. population, their mothers and close friends participated in this study. Data collection began when adolescents were in 10th grade (¬Average age = 15.9, SD = .52) and continued for the next five and a half years. Results indicated that teens engaged in positive problem solving, withdrawal, and compliance far more frequently than in aggressive conflict resolution strategies. Hierarchical linear modeling …

Cortisol Reactivity Across The Day At Child Care: Examining The Contributions Of Child Temperament And Attachment To Mother And Lead Teacher, Lisa S. Badanes

Electronic Theses and Dissertations

Previous work has shown that full-day center-based child care is associated with increased physiologic stress for many young children (e.g., Tout, de Haan, Campbell, & Gunnar, 1998; Watamura, Sebanc, & Gunnar, 2002). Specifically, increasing cortisol from morning to afternoon at full-day child care in contrast to decreasing cortisol across the day for these same children at home has been repeatedly demonstrated for toddlers and preschoolers. Factors that have been related to rising cortisol across the day at child care include the child's age (rising cortisol at child care between 2 and 5 years, but not for infants or older children, …

Revictimization: A Multi-Method Approach To Understanding Risk Detection, Ann Chu

Electronic Theses and Dissertations

Research has focused on identifying mechanisms that increase revictimization risk in women, such as risk detection (i.e., ability to identify threat). While risk detection deficits have been linked to revictimization in college samples, individual differences that might predict risk detection deficiencies remain unclear. In this study, 94 women recruited from the community performed a risk detection task by listening to an audiotape of a risky dating situation. We obtained parasympathetic (e.g., vagal tone) and sympathetic (e.g., pre-ejection period) activation, heart rate, and self-reported emotional responding while participants completed the task. We also assessed participants' trauma histories and relevant symptoms. Results …

The Humiliation Experience: Causes, Emotional Correlates, And Behavioral Consequences, Kendall Elyse Mccarley

Electronic Theses and Dissertations

The goal of this research was to provide a comprehensive investigation of the emotional experience of humiliation by examining: (1) the direct effects of self-esteem and narcissism on emotional responses to potentially humiliating events; (2) the direct effects of the emotional correlates of humiliating experiences (i.e. sadness, humiliation, and anger) on the related behavioral reactions to such events (i.e., withdrawal, retaliation, and minimization); and (3) a process model to determine whether or not the emotional correlates of potentially humiliating events mediated the predicted effects of self-esteem and narcissism on the behavioral consequences on those events.

Participants, ranging in age from …

Relational Financial Satisfaction Of Cohabiting Couples, Christine C. Mcdunn

Electronic Theses and Dissertations

The current study tested a model of factors affecting cohabiting couples' relational financial satisfaction, defined as the contentment an individual has with how financial issues are handled within his or her domestic romantic relationship, and examined the relations within these factors. This study was a cross-sectional online survey of 266 participants (81% female; 85% Caucasian) recruited from listservs and subsequent snowball sampling. Measures assessed couples' financial strain, dedication commitment, financial conflict, financial trust, financial equality and financial communication. Relational financial satisfaction (RFS) was significantly related to financial conflict, financial strain and dedication commitment. Financial conflict mediated the association between …

Gene X Environment Interactions In Developmental Dyslexia, Lauren M. Mcgrath

Electronic Theses and Dissertations

The goal of this project was to advance understanding of the complex multifactorial etiology of developmental dyslexia, or reading disability (RD), by investigating gene x environment (G x E) interactions. This project tested for G x E interactions using molecular genetic methods and measures of psychosocial and bioenvironmental risk factors. There are two competing predictions that can be derived from existing G x E models about the expected direction of interactions in RD. There could be "diathesis-stress" interactions in which the effects of genotype are stronger in risk environments, or there could be "bioecological" interactions in which the effects of …

Humiliation And Its Relationship To Embarrassment And Shame, Danielle Jean Pulham

Electronic Theses and Dissertations

This study aimed to expand our knowledge of humiliation by examining the cognitive correlates of this emotion. Since norm violations may often elicit this emotion, attributions of blame and perceived devaluation of the self from others were investigated as possible cognitions that may both link and distinguish this emotion from close emotion relatives, namely embarrassment and shame.

Participants were presented with vignettes that described a social versus moral norm violation. Blame for the event was manipulated by varying who/what caused the norm violation. Perceived devaluation was manipulated by varying what the observing audience knew about the cause of the norm …

Mitigating Risk For Anxiety Among Preschool-Age Children Living In Poverty: Evaluating The Impact Of Adult-Provided Social Support On Autonomic Stress Reactivity, Brian Cory Wolff

Electronic Theses and Dissertations

Poverty increases children's exposure to stress, elevating their risk for developing patterns of heightened sympathetic and parasympathetic stress reactivity. Repeated patterns of high sympathetic activation and parasympathetic withdrawal place children at risk for anxiety disorders. This study evaluated whether providing social support to preschool-age children during mildly stressful situations helps reduce reactivity, and whether this effect partly depends on children's previously assessed baseline reactivity patterns. The Biological Sensitivity to Context (BSC) theory proposes that highly reactive children may be more sensitive than less reactive children to all environmental influences, including social support. In contrast, conventional physiological reactivity (CPR) theory contends …

The Provision Of Social Support By Adolescent Youth And Their Subsequent Risk For Secondary Traumatic Stress Reactions, Lindsay E. Smart

Electronic Theses and Dissertations

During adolescence, peers become increasingly important sources of social support for youth. In addition to discussing the trials and tribulations of daily life, it is possible that youth are having intimate conversations concerning their experiences of trauma. This study examined the types of traumatic experiences disclosed to youth by their friends, youth's experiences of supporting a friend following disclosure of trauma, youth's secondary traumatic stress (STS) reactions to their friends' disclosures, and potential risk factors for the development of STS. The validity of an adult measure of STS, the Secondary Trauma Scale, with an adolescent population was also explored. Utilizing …
