Available in PDF, EPUB and Kindle. Book excerpt: Recently, with the development of new technology, researchers have focused on physiological predictors of aggressive behavior, specifically cortisol and alpha amylase. Gordis, Granger, Susman, and Trickett (2006) found the interaction between cortisol and alpha-amylase significantly predicted parent reports of aggression indicating that low levels of physiological reactivity was associated with higher levels of problem behavior. While this research has provided valuable information about aggressive behavior, a major limitation is the majority of research focuses on males, or has not examined gender differences explicitly. This study expanded on work by Gordis et al. (2006) and other researchers on the HPA axis and sympathetic nervous system responses and aggression by using a larger sample, focusing on female adolescents, examining both physical and relational aggression, and utilizing parent and adolescent reports of aggressive behavior. Based on prior literature, I expected that lower levels of salivary cortisol taken at the beginning of the interview and the beginning of the stress task would be associated with higher levels of physical and relational aggression in girls. I also hypothesized that lower levels of cortisol and [alpha]-amylase reactivity will be associated with higher levels of physical and relational aggression. Finally, I hypothesized that lower levels of cortisol reactivity coupled with higher levels of [alpha]-amylase reactivity will be associated with lower levels of aggressive behavior. Participants in the current study live in moderate- to high-violence areas in Richmond, VA. Participants were 146 adolescent females who were enrolled in a larger longitudinal study on coping with exposure to violence. Most of the adolescents were African-American (91.1%) with a mean age of 13.9 years old (range from 11-17). The changes in physiological responses were monitored during the interview process which included the administration of the Social Competence Interview (SCI). Aggression was measured using the Child Behavior Checklist and Problem Behavior Frequency Scales. In the analyses, I controlled for pubertal status, medication usage, race, and time of day which are all factors that can influence the level of cortisol and alpha-amylase. Results indicated that higher levels of basal cortisol were associated with higher levels of aggressive behavior. In contrast to previous research and prediction, results indicated that symmetry in [alpha]-amylase and cortisol predicted lower levels of self-reported physical aggression in girls. Asymmetry in the two systems was associated with higher levels of self-reported physical aggression. These results contribute to the mixed results on female physiological responses and aggression. It also provides support for symmetry in cortisol and [alpha]-amylase as a predictor of lower levels of aggressive behavior. Studying a child's physiological reactions to stress can give insight into behavior regulation, help identify adolescents for prevention/intervention, and serve as markers of treatment progress. These data suggest that physiological associations with aggression may not be the same for males and females, or for youth living in extremely stressful circumstances. Further research is needed to replicate these finding, and specifically to compare these patterns of associations across gender.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conduct problems in youth, including aggression, constitute a significant and increasing public health burden. Despite replicated evidence that conduct problems in girls predict numerous poor outcomes (e.g., health, substance use), research on aggression is focused almost exclusively on boys, thus perpetuating significant gaps in knowledge about risk factors, explanatory processes, and outcomes in girls. In boys, threat-biased social information processing is a correlate of aggressive behavior, particularly reactive aggression (i.e., retaliatory response to perceived threat/provocation). Elevated trait negative emotionality, the dispositional tendency to experience negative affective states such as anger and sadness, is a transdiagnostic risk factor for emotional and behavioral problems that may plausibly interfere with social cognition to promote aggression. Individual differences in autonomic functioning, including respiratory sinus arrhythmia (RSA), are also replicated risk factors for emotional and behavioral problems, as aberrant psychophysiological responding can have pronounced effects on emotional reactivity and regulation. Despite theoretical rationale and empirical support from research with boys and men, the associations of social information processing, elevated trait negative emotionality, and RSA with respect to aggression in girls remain largely unknown. To inform models of aggressive behavior in girls, the goals of these dissertation studies were to evaluate individual differences in negative emotionality, social information processing, and psychophysiology (i.e., RSA) as correlates of conduct problems, including separate dimensions of aggression (e.g., relational aggression). Using a sample of ethnically diverse pre-adolescent girls, Study I evaluated trait negative emotionality and threat-biased encoding and interpretation processes as sequential predictors of conduct problems. Preliminary evidence suggested that the hypothesized chain reaction effect marginally predicted both reactive relational aggression and general aggressive behavior. In the same sample, Study II assessed initial RSA and RSA withdrawal (i.e., reductions in RSA, also referred to as RSA reactivity), during a novel social information processing task, as correlates of conduct problems. Excessive RSA withdrawal was associated with higher levels of reactive relational aggression, and RSA initial values were inversely associated with rule-breaking behavior. Although these findings largely align with previous findings from male samples, reactive physical aggression was generally unrelated to aberrant social cognition and individual differences in RSA, unlike previous evidence based mostly on boys. Collectively, these preliminary findings fill critical gaps in knowledge on aggression and conduct problems in girls, informing the design of future studies that can propel targeted prevention and intervention approaches that are specific to risk factors and processes in girls.

This book was released on 2016-09-14 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bullying has long been tolerated as a rite of passage among children and adolescents. There is an implication that individuals who are bullied must have "asked for" this type of treatment, or deserved it. Sometimes, even the child who is bullied begins to internalize this idea. For many years, there has been a general acceptance and collective shrug when it comes to a child or adolescent with greater social capital or power pushing around a child perceived as subordinate. But bullying is not developmentally appropriate; it should not be considered a normal part of the typical social grouping that occurs throughout a child's life. Although bullying behavior endures through generations, the milieu is changing. Historically, bulling has occurred at school, the physical setting in which most of childhood is centered and the primary source for peer group formation. In recent years, however, the physical setting is not the only place bullying is occurring. Technology allows for an entirely new type of digital electronic aggression, cyberbullying, which takes place through chat rooms, instant messaging, social media, and other forms of digital electronic communication. Composition of peer groups, shifting demographics, changing societal norms, and modern technology are contextual factors that must be considered to understand and effectively react to bullying in the United States. Youth are embedded in multiple contexts and each of these contexts interacts with individual characteristics of youth in ways that either exacerbate or attenuate the association between these individual characteristics and bullying perpetration or victimization. Recognizing that bullying behavior is a major public health problem that demands the concerted and coordinated time and attention of parents, educators and school administrators, health care providers, policy makers, families, and others concerned with the care of children, this report evaluates the state of the science on biological and psychosocial consequences of peer victimization and the risk and protective factors that either increase or decrease peer victimization behavior and consequences.

Download or read book Perspectives on Aggression written by Russell G. Geen and published by Elsevier. This book was released on 2013-10-22 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives on Aggression is a compendium of papers that discusses experimental research on human and group aggression. This compendium deals with the psychology of aggression including interracial aggression, environmental factors that contribute to aggression, and the role of mass media in "perpetuating" violence. A couple of papers review aggression in terms of variable aggression research and of the Darwinian Theory. One author notes that results of psychological studies of animals can suggest further hypotheses for human research. Another paper examines moral judgment in aggressive behavior such as shown in society's different attitudes toward an aggressive act. Another paper studies the effects of personality variables on aggressive behaviors, which indicate that some aggressive responses can be dependent on the control exerted toward such personality variables. Another paper reviews the works of Buss and Berkowitz, particularly the nature of arousal in aggression both from a physiological and a cognitive point of view. This book can be appreciated by psychologists, psychiatrists, social workers, counselors, and officials related to issues of peace and security.

Available in PDF, EPUB and Kindle. Book excerpt: Unchecked aggression and violence take a significant toll on society. Even if we manage to avoid being the direct victim of a violent act, the effects of aggression and violence reach us all: We hear about the mauling of a woman by an aggressive dog, our children are bullied at school, or we deal with impulsive violence while commuting to work or attending a sporting event. Reflecting psychology in general, the dominant roles of learning and environmental influences - both social and nonsocial - have traditionally been prominent in discussions of the etiology of human aggression. Biological factors have not been considered sufficiently important to investigate in the search for ways of dealing with human aggression or violence. With recent advances in pharmacology and genetic manipulation techniques, however, new interest has developed in the biological mechanisms of both non-human and human aggression. Although aggression is certainly a complex social behavior with multiple causes, molecular biological factors should not be overlooked, as they may well lead to interventions that prevent excess aggressive behaviors. The primary goal of this book is to summarize and synthesize recent advances in the biological study of aggression. As most aggressive encounters among human and non-human animals represent a male proclivity, the research in this book describes and discusses studies using the most appropriate murine model: testosterone-dependent offensive inter-male aggression, which is typically measured in resident-intruder or isolation-induced aggression tests. The research also emphasizes various molecules that have been linked to aggression tests. The research also emphasizes various molecules that have been linked to aggression by the latest gene-targeting and pharmacological techniques. Although the evidence continues to point to androgens and serotonin (5-HT) as major hormonal and neurotransmitter factors in aggressive behavior, recent work with GABA, dopamine, vasopressin, and other factors, such as nitric oxide, has revealed significant interactions with the neural circuitry underlying aggression. This book is organized according to levels of analysis. The first section examines the genetic contributions to aggression in species ranging from crustaceans to humans. The section summarizes the involvement of various neurotransmitters and neuromodulators in aggressive behavior. The third section summarizes the influence of hormones on aggression, primarily in humans. All chapters emphasize future directions for research on aggression and reveal important domains that have received comparatively less attention in this literature. Considered together, these chapters provide up-to-date coverage of the biology of aggression by some of the leading authorities currently working in this field. Biology of Aggression will direct future research to continue the recent advances in the pharmacological and genetic approaches to understanding aggression and violence. It promises to be a valuable resource for professional and student researchers in neuroscience, psychiatry, cognitive and developmental psychology, behavioral biology, and veterinary medicine.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is an overview of research examining the relationship between hormones and aggressive behavior. The last 15 years have witnessed a tremen dous growth of knowledge in this area, yet reviews written by specialists are virtually nonexistent. This work is an attempt to provide a comprehensive and cohesive synthesis of this literature. Chapters 1-7 provide an analysis of hor monal influences on the major forms of aggressive behavior, including intermale, interfemale, shock-induced, maternal, territorial, and predatory aggression. The focus of Chapters 8-12 is an examination of the mechanisms through which hormones might act to produce changes in agonistic responding. Genetic, de velopmental, neural, and biochemical influences are considered. It is well known that environment, social context, and experience modulate the effects of hor mones on behavior. Thus, Chapters 13-15 are designed to review the literature concerning hormone-pheromone interactions, hormonal responses to compe tition, and the influence of social context on the endocrine system and aggressive behavior. Frequently, the principles advanced by behavioral endocrinologists are based on research in one species, the rodent. To provide a more comparative perspective and to examine specifically the generality of those principles gen erated for rodents, Chapters 16-22 examine hormone-aggression relationships in a variety of species, including fish, birds, amphibians, reptiles, infrahuman primates, humans, ungulates, and insects. This volume should be useful to both beginning and advanced researchers in animal behavior, behavioral endocri nology, physiological psychology, neuroendocrinology, zoology, physiology, and psychiatry.

Download or read book Aggressive Behavior written by Edward C. Simmel and published by Routledge. This book was released on 2021-09-30 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the heyday of research on aggression in the late 1960s, developments in several varied areas had enabled us to take a new look at this important though difficult topic. Recent findings and sophisticated new techniques in behavior genetic analysis at the time had made it possible not only to enhance our understanding of the genetic mechanisms underlying aggressive behavior, but also to provide some reasonable suggestions as to the role of aggression in evolution. Originally published in 1983, there had been significant advances in genetic and neural research and a much more sophisticated and heuristic approach to the measurement and conceptualization of aggressive behavior had developed. The ten chapters in this volume provide a thorough overview of these new approaches and methodologies. There are also suggestions regarding the scope of future research on aggressive behavior, since much of what is presented describes the ongoing research activities of the contributors. This book is divided into four sections: The first provides a systematic foundation for research on aggression, and a description of some of the newer strategies for research in this area; the second concerns quantitative genetic analyses, selection data from both wild and laboratory populations, and situational determinants of aggressive behavior; the third section details new and exciting findings in neurochemical and neuropharmacological effects; and the last section contains a chapter that provides a summary and synthesis of all that has come before.

Download or read book Understanding Peer Influence in Children and Adolescents written by Mitchell J. Prinstein and published by Guilford Press. This book was released on 2008-05-13 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists, educators, and parents of teens have long recognized the potency of peer influences on children and youth, but until recently, questions of how and why adolescents emulate their peers were largely overlooked. This book presents a comprehensive framework for understanding the processes by which peers shape each other's attitudes and behavior, and explores implications for intervention and prevention. Leading authorities share compelling findings on such topics as how drug use, risky sexual behavior, and other deviant behaviors "catch on" among certain peer groups or cliques; the social, cognitive, developmental, and contextual factors that strengthen or weaken the power of peer influence; and the nature of positive peer influences and how to support them.

Download or read book Social Aggression Among Girls written by Marion K. Underwood and published by Guilford Press. This book was released on 2003-04-10 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: While several recent popular books address the topic of girls' "meanness" to one another, this volume offers the first balanced, scholarly analysis of scientific knowledge in this area. Integrating current research on emotion regulation, gender, and peer relations, the book examines how girls are socialized to experience and express anger and aggression from infancy through adolescence. Considered are the developmental functions of such behaviors as gossip, friendship manipulation, and social exclusion; consequences for both victims and perpetrators; and approaches to intervention and prevention. Presenting innovative research models and methods, this is an accessible and much-needed synthesis for researchers, professionals, and students. Key Features: * Hot topic, garnering coverage in general media (e.g., The New York Times Magazine) * Accessibly written, with examples clarifying abstract points * Covers and integrates both physical and social aggression
