Social and Emotional Development, a new four-volume collection from Psychology Press, brings together the most influential and fundamental research in the area, providing readers with a vital overview of the basic theory and the empirical database regarding social and emotional development. The collection editors present a general developmental picture of the state-of-the-art in each area of social and emotional development. They have also written integrative commentaries (appearing as an introduction at the start of each volume) to situate the collected research topics in their historical and intellectual context, and to provide a snapshot of current issues in the field. The collection is an ideal introduction to social and emotional development for advanced undergraduates and graduate students, and will serve as an important reference for instructors. Indeed, teachers who are planning courses intended for advanced undergraduates and graduate students will find these volumes to be an ideal way of providing a comprehensive and in-depth coverage of research on social and emotional development. The chronological organization of three of the four volumes will allow instructors to use all three or to choose the book that best fits the needs of their course. The models-and-methods volume can be used in a similarly flexible or focused manner. For anyone interested in social and emotional development, this new Major Work constitutes a 'mini library' on the history of, and current debates in, social and emotional development. Beyond its immediate relevance to those working in developmental psychology, the collection will be of interest to individuals from disciplines including: counselling and school psychology, human development, family studies, kinesiology, sport psychology, educational psychology, sociology, anthropology, criminal justice (especially the collected material on aggression), child psychiatry, social work, early childhood education, and public policy.

The papers in this special issue apply two recent data analytic techniques to the study of family and close peer relationships. The Actor-Partner Interdependent Model incorporates the perspectives of both participants in a dyad into analyses that describe shared and unique views of the relationship. The Social Relations Model incorporates the perspectives of all members of a group into analyses that ascribe views unique to individuals and relationships, and views shared by the entire group. Developmental applications of techniques originally designed for concurrent interdependent data are described.

The volume's topic was chosen in part because of the rapidly growing salience of dyadic research perspectives in developmental psychology, but also in social psychology and in fields such as communication and family studies. It provides the most complete representation now available on current theory and research on the significance of personal relationships in child and adolescent development. This volume addresses the ways in which the study of social development has been altered by an emphasis on research questions and techniques for studying children and adolescents in the context of their significant dyadic relationships. Leading scholars--many of them pioneers in the concepts and methods of dyadic research--have contributed chapters in which they both report findings from recent research and reflect on the implications for developmental psychology. Their work encompasses studies of relationships with parents, siblings, friends, and romantic partners. Opening chapters set the stage by describing the key characteristics of social-development research from a dyadic perspective and outlining key themes and contemporary issues in the field. It concludes with commentaries from distinguished senior scholars identifying important directions for future research.

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.

*Authoritative reference, updated and expanded; 55% new material includes new topics, such as neuroscience, social media, social inequality, and novel interventions. *Cutting-edge coverage of perennial topics, including aggression, withdrawal, psychopathology, friendships, romance, and the influence of families and schools. *Interdisciplinary contributors include experts from developmental and clinical psychology, family studies, and sociology. *Competing titles are dated and less comprehensive.

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.
