The definitive handbook on peer relations has now been significantly revised with 55% new material. Bringing together leading authorities, this volume presents cutting-edge research on the dynamics of peer interactions, their impact on multiple aspects of social development, and the causes and consequences of peer difficulties. From friendships and romance to social withdrawal, aggression, and victimization, all aspects of children's and adolescents' relationships are explored. The book examines how individual characteristics interact with family, group, and contextual factors across development to shape social behavior. The importance of peer relationships to emotional competence, psychological well-being, and achievement is analyzed, and peer-based interventions for those who are struggling are reviewed. Each chapter includes an introductory overview and addresses theoretical considerations, measures and methods, research findings and their implications, and future directions. New to This Edition *Chapters on neuroscience, social media, social inequality, prosocial behavior with peers, and sociological approaches. *Expanded coverage of applied issues: chapters on interventions for socially withdrawn children, activity programs that promote positive youth development, and policy initiatives. *Chapters on same- and other-sex peer relationships, peer influence, educational environments, evolutionary models, the self-concept, personality, and animal studies. *Increased attention to variations in peer relations due to culture, gender, and race. *Many new authors and topics reflect a decade's worth of theoretical and methodological advances, including the growing use of complex longitudinal methods.

This comprehensive, authoritative handbook covers the breadth of theories, methods, and empirically based findings on the ways in which children and adolescents contribute to one another's development. Leading researchers review what is known about the dynamics of peer interactions and relationships from infancy through adolescence. Topics include methods of assessing friendship and peer networks; early romantic relationships; individual differences and contextual factors in children's social and emotional competencies and behaviors; group dynamics; and the impact of peer relations on achievement, social adaptation, and mental health. Salient issues in intervention and prevention are also addressed.

Appropriate for use in developmental research methods or analysis of change courses, this is the first methods handbook specifically designed to meet the needs of those studying development. Leading developmental methodologists present cutting-edge analytic tools and describe how and when to use them, in accessible, nontechnical language. They also provide valuable guidance for strengthening developmental research with designs that anticipate potential sources of bias. Throughout the chapters, research examples demonstrate the procedures in action and give readers a better understanding of how to match research questions to developmental methods. The companion website (www.guilford.com/laursen-materials) supplies data and program syntax files for many of the chapter examples.

Highly readable and comprehensive, this volume explores the significance of friendship for social, emotional, and cognitive development from early childhood through adolescence. The authors trace how friendships change as children age and what specific functions these relationships play in promoting adjustment and well-being. Compelling topics include the effects of individual differences on friendship quality, how friendship quality can be assessed, and ways in which certain friendships may promote negative outcomes. Examining what clinicians, educators, and parents can do to help children who struggle with making friends, the book reviews available interventions and identifies important directions for future work in the field.

This volume represents the first collection of empirical studies focusing on peer interaction for L2 learning. These studies aim to unveil the impact of mediating variables such as task type, mode of interaction, and social relationships on learners’ interactional behaviors and language development in this unique and pedagogically powerful learning context. To examine these issues, contributors employed quantitative, qualitative, and mixed-methods designs as well as cognitive, social, and sociocognitive theoretical frameworks. The majority of the studies are classroom based and were conducted in a rich array of settings covering five continents and encompassing a wide range of learner L1s and target languages. These settings include second and foreign language classrooms from primary to university level, content-based programs, online contexts, and after-school programs. To span the divide between research and practice, each study includes a section suggesting pedagogical implications.

"Socialization refers to the way in which individuals are assisted in becoming members of one or more social groups, including how the newer members as well as the established ones socialize one another, often in a bi-directional manner, that is, response to socialization impact in both directions. This is the only handbook on socialization that covers the topic from infancy through adulthood. Hot new topics include moral development; the media as a socializing agent; behavior genetics; and, culture. Authors are known in the field"--Résumé de l'éditeur.
