Connecting traditional Piagetian, information processing, and psychometric approaches with newer frameworks and tools for the assessment and analysis of change, this book provides a cutting-edge account of the latest theory and research. Chapters cover key theories of cognitive change, the factors that affect change including neurological, emotional and socio-cultural factors and the latest methods for measuring and modelling change.

Emerging Themes in Cognitive Development presents two volumes of the newest research and theory in cognitive development available at the outset of the 1990s. These ideas are firmly rooted in research from the 1980s and, in some sense, these volumes represent a culmination of that research and of even earlier work. Nevertheless, these volumes are offered as catalysts more than summaries, because each presents the freshest and most recently gathered data of many scientists whose insights have had an important impact on the field. The latest ideas of these researchers will, in some cases, immediately prove to be dominant themes of research and theory. In other cases, of course, it will take longer for the concepts presented to capture the imagination of students and colleagues who are still invested in meritori ous research on other themes. In either case, the syntheses and innova tions proposed are not likely to escape the careful study of the serious scholar, and it is to such scholars that these volumes are dedicated.

Cognitive Development from a Strategy Perspective recognises the outstanding scientific legacy of Robert S. Siegler as a pioneer of modern research on cognitive development throughout the lifespan. This volume presents a collection of essays written by leading scholars in the field, using cutting-edge research to illustrate how Siegler’s work and ideas lay the groundwork for much of the modern studies on cognitive development. The collection includes chapters which examine strategic aspects of lifespan cognitive development, change mechanisms underlying cognitive development, and numeracy acquisition with emphasis given to the application of new strategies for education. It explores conceptual and methodological frameworks to best study and understand development during childhood and adulthood, and the role of foundational core knowledge on development and acquisition. These foundational issues are examined from various angles and finally integrated in a concluding panoramic chapter written by Siegler himself. Cognitive Development from a Strategy Perspective offers valuable reading for graduates and researchers in cognitive development and mathematical cognition, as well as those at the interface of psychology and education.

Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Are humans born good? Or do children learn to be moral? Where do concepts like "democracy" and "atom" come from? This volume documents ground-breaking answers to these questions from developmental psychology, including new science on language, morality, causal explanation, and children's understanding of time, numbers, and other minds.

How do children acquire the vast array of concepts, strategies, and skills that distinguish the thinking of infants and toddlers from that of preschoolers, older children, and adolescents? In this new book, Robert Siegler addresses these and other fundamental questions about children's thinking. Previous theories have tended to depict cognitive development much like a staircase. At an early age, children think in one way; as they get older, they step up to increasingly higher ways of thinking. Siegler proposes that viewing the development within an evolutionary framework is more useful than a staircase model. The evolution of species depends on mechanisms for generating variability, for choosing adaptively among the variants, and for preserving the lessons of past experience so that successful variants become increasingly prevalent. The development of children's thinking appears to depend on mechanisms to fulfill these same functions. Siegler's theory is consistent with a great deal of evidence. It unifies phenomena from such areas as problem solving, reasoning, and memory, and reveals commonalities in the thinking of people of all ages. Most important, it leads to valuable insights regarding a basic question about children's thinking asked by cognitive, developmental, and educational psychologists: How does change occur?

This volume considers how children's thinking evolves during development, with a focus on the role of experience in causing change. It brings together cutting-edge research by leaders in the psychology and neurobiology of child development to examine the processes by which children learn and those that make children ready and able to learn at particular points in development. Behavioral approaches include research on the "microgenesis" of cognitive change over short time periods (e.g., several hour-long sessions) in specific task situations. Research on cognitive change over longer time scales (months and years) is also presented, as well as research that uses computational modeling and dynamical systems approaches to understand learning and development. Neural approaches include the study of how neuronal activity and connectivity change during acquisition of cognitive skills in children and adults. Other investigations consider the possible emergence of cognitive abilities through the maturation of brain structures and the effects of experience on the organization of functions in the brain. Developmental anomalies, such as autism and attention deficit disorder are also examined as windows on normal development. Four questions drive the volume: *Why do cognitive abilities emerge when they do during development? *What are the sources of developmental and individual differences, and of developmental anomalies in learning? *What happens in the brain when people learn? *How can experiences be ordered and timed to optimize learning? The answers to these questions have strong implications for how we educate children and remediate deficits that have impeded the development of thinking abilities. These implications are explored in several chapters in the volume, as well as in the commentaries by leading discussants.
