Key issues in the development of aggression and violence from childhood to early adulthood

Abstract: Different manifestations of aggression from childhood to early adulthood are reviewed to establish how early manifestations are related to later manifestations. Similarities and differences in manifestations of aggression between the two genders are noted. Developmental sequences and pathways from minor aggression to violence are highlighted. Long-term escalation is contrasted with short-term escalation at older ages. Although studies have emphasized high stability of aggression over time, data show that a substantial proportion of aggressive youth desist over time. Temperamental, emotional, and cognitive aspects of aggression are reviewed, either as precursors or co-occurring conditions to aggression. Selected processes in the realms of the family, peers, and neighborhoods are highlighted that are known to be associated with juvenile aggression. Cumulative, long-term causes are contrasted with short-term causes, and causes associated with desistance in aggression are reviewed.

Peer relations in childhood

Abstract: We present a developmental model that describes normal peer relations and highlights processes that underlie the emergence of problems with peers in childhood. We propose that children's relationships with peers begin in the first years of life, with stable individual differences and preferences for particular peers emerging by three years of age. Social skills that facilitate peer relationships consolidate in the preschool years, during which time peer groups become structured with respect to friendship groups, gender, and dominance relations; some children begin to be rejected by their peers. In later childhood some children develop entrenched problems with peer relationships, in terms of loneliness, bullying and victimisation. Underlying cognitive and emotional processes that facilitate successful peer relationships at all ages are identified, and the extent to which peer relations play a causal role in the genesis of disorder is evaluated. A review of the evidence suggests that, rather than a simple pathway from problematic peer relations to disorder, there is a reciprocal relationship between children's problems with peers and their psychological problems from infancy to adolescence.

Intellectual problems shown by 11-year-old children whose mothers had postnatal depression.

Abstract: The aim of the study was to examine long-term sequelae in the children of mothers who were depressed at 3 months postpartum. In a community sample from two general practices in South London, 149 women were given psychiatric interviews at 3 months postpartum and 132 of their children (89%) were tested at 11 years of age. The children of women who were depressed at 3 months postpartum had significantly lower IQ scores. They also had attentional problems and difficulties in mathematical reasoning, and were more likely than other children to have special educational needs. Boys were more severely affected than girls, with the sex difference most pronounced on Performance IQ. The links between postnatal depression and the children's intellectual problems were not mediated by parental IQ and were not accounted for by measures of social disadvantage nor by the mother's later mental health problems. Breastfeeding did not remove the effect of the mother's illness on Full Scale IQ, but exerted its own influence on Verbal IQ and appeared to mediate the link with mathematical ability. The findings show that adverse experiences in infancy predict cognitive ability and academic performance a decade later.

Maternal smoking during pregnancy and attention deficit hyperactivity disorder symptoms in offspring

Abstract: OBJECTIVE: The aim of this study was to examine whether smoking during pregnancy is associated with symptoms of attention deficit hyperactivity disorder (ADHD) in offspring and whether these effects are additional to genetic influences. METHOD: Children’s ADHD symptoms (parent- and teacher-rated), maternal smoking during pregnancy, conduct disorder symptoms, and family adversity were assessed with questionnaires for a population-based sample of twins (1,452 twin pairs 5–16 years of age). RESULTS: Although genetic influences accounted for most of the variance in offspring ADHD, maternal smoking during pregnancy was still found to show a significant environmentally mediated association. Maternal smoking remained a significant influence when other potential confounds were taken into account. CONCLUSIONS: Maternal smoking during pregnancy appears to show an association with offspring ADHD symptoms that is additional to the effects of genes and not attributable to shared rater effects, clinical referral biases...

The impact of postnatal depression on boys intellectual development

Abstract: A follow-up study was carried out to investigate the children of 204 mothers who had previously participated in a study of their mental health during pregnancy and the first postnatal year. One hundred and seventy two children, 170 mothers, and 99 fathers were assessed when the children were 3 years 10 months. Boys of mothers depressed in the first year postpartum scored approximately 1 standard deviation lower on standardised tests of intellectual attainment than boys whose mothers were well that year. The difference was reliable even when behaviour during the test was controlled for, and general behavioural problems, birth weight, parental IQ, measures of the family climate and home environment, mother-child interaction, and breast-feeding during infancy were taken into account.

From Neurons to Neighborhoods: The Science of Early Childhood Development

Abstract: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

스크린 위의 삶 = Life on the screen : identity in the age of the internet

Abstract: From the Publisher: A Question of Identity Life on the Screen is a fascinating and wide-ranging investigation of the impact of computers and networking on society, peoples' perceptions of themselves, and the individual's relationship to machines. Sherry Turkle, a Professor of the Sociology of Science at MIT and a licensed psychologist, uses Internet MUDs (multi-user domains, or in older gaming parlance multi-user dungeons) as a launching pad for explorations of software design, user interfaces, simulation, artificial intelligence, artificial life, agents, "bots," virtual reality, and "the on-line way of life." Turkle's discussion of postmodernism is particularly enlightening. She shows how postmodern concepts in art, architecture, and ethics are related to concrete topics much closer to home, for example AI research (Minsky's "Society of Mind") and even MUDs (exemplified by students with X-window terminals who are doing homework in one window and simultaneously playing out several different roles in the same MUD in other windows). Those of you who have (like me) been turned off by the shallow, pretentious, meaningless paintings and sculptures that litter our museums of modern art may have a different perspective after hearing what Turkle has to say. This is a psychoanalytical book, not a technical one. However, software developers and engineers will find it highly accessible because of the depth of the author's technical understanding and credibility. Unlike most other authors in this genre, Turkle does not constantly jar the technically-literate reader with blatant errors or bogus assertions about how things work. Although I personally don't have time or patience for MUDs,view most of AI as snake-oil, and abhor postmodern architecture, I thought the time spent reading this book was an extremely good investment.

Peer Interactions, Relationships, and Groups

Abstract: The chapter begins with a distinction made between the interactions children have with peers, the relationships they form with peers, and the groups and networks within which peer interactions and relationships occur. From this conceptual overview, a review of relevant theories is presented. Thereafter, a developmental perspective of peer interactions, relationships, and groups is presented covering the periods of infancy, toddlerhood, early childhood, middle childhood, and adolescence. Subsequently, methods and measures pertaining to the study of children's peer experiences are described. Next, we examine factors that may account for peer acceptance and rejection as well as qualitatively rich and poor friendships. Among the factors discussed are included temperament (biological factors), sex of child, parenting, parent-child relationships, and culture. The chapter concludes with a discussion of the extent to which individual differences in peer acceptance, rejection and friendship (prevalence and quality) predict adaptive and maladaptive developmental outcomes and a suggested agenda for future research. Keywords: friendship; peer interactions; peer relationships; peer rejection; social acceptance; social competence

Risk for psychopathology in the children of depressed mothers: a developmental model for understanding mechanisms of transmission.

Abstract: A large body of literature documents the adverse effects of maternal depression on the functioning and development of offspring. Although investigators have identified factors associated with risk for abnormal development and psychopathology in the children, little attention has been paid to the mechanisms explaining the transmission of risk from the mothers to the children. Moreover, no existing model both guides understanding of the various processes' interrelatedness and considers the role of development in explicating the manifestation of risk in the children. This article proposes a developmentally sensitive, integrative model for understanding children's risk in relation to maternal depression. Four mechanisms through which risk might be transmitted are evaluated: (a) heritability of depression; (b) innate dysfunctional neuroregulatory mechanisms; (c) exposure to negative maternal cognitions, behaviors, and affect; and (d) the stressful context of the children's lives. Three factors that might moderate this risk are considered: (a) the father's health and involvement with the child, (b) the course and timing of the mother's depression, and (c) characteristics of the child. Relevant issues are discussed, and promising directions for future research are suggested.

Informant discrepancies in the assessment of childhood psychopathology: a critical review, theoretical framework, and recommendations for further study.

Abstract: Discrepancies often exist among different informants' (e.g., parents, children, teachers) ratings of child psychopathology. Informant discrepancies have an impact on the assessment, classification, and treatment of childhood psychopathology. Empirical work has identified informant characteristics that may influence informant discrepancies. Limitations of previous work include inconsistent measurement of informant discrepancies and, perhaps most importantly, the absence of a theoretical framework to guide research. In this article, the authors present a theoretical framework (the Attribution Bias Context Model) to guide research and theory examining informant discrepancies in the clinic setting. Needed directions for future research and theory include theoretically driven attention to conceptualizing informant discrepancies across informant pairs (e.g., parent-teacher, mother-father, parent-child, teacher-child) as well as developing experimental approaches to decrease informant discrepancies in the clinic setting.
