Developing Cognitive Competence

Although computational modeling is now a widespread technique in cognitive science and in psychology, relatively little work in developmental psychology has used this technique. The approach is not entirely new, as a small group of researchers has attempted to create computational accounts of cognitive developmental phenomena since the inception of the technique. It should seem obvious that transition mechanisms -- or how the system progresses from one level of competence to the next -- ought to be the central question for investigation in cognitive developmental psychology. Yet, if one scans the literature of modern developmental studies, it appears that the question has been all but ignored. However, only recently have advances in computational technology enabled the researcher access to fully self-modifying computer languages capable of simulating cognitive change. By the beginning of the 1990s, increasing numbers of researchers in the cognitive sciences were of the opinion that the tools of mathematical modeling and computer simulation make theorizing about transition mechanisms both practical and beneficial -- by using both traditional symbolic computational systems and parallel distributed processing or connectionist approaches. Computational models make it possible to define the processes that lead to a system being transformed under environmental influence from one level of competence observed in children to the next most sophisticated level. By coding computational models into simulations of actual cognitive change, they become tangible entities that are accessible to systematic study. Unfortunately, little of what has been produced has been published in journals or books where many professionals would easily find them. Feeling that developmental psychologists should be exposed to this relatively new approach, a symposium was organized at the biennial meeting of the Society for Research in Child Development. The "cost of entry" was that speakers had to have a running computational model of a documented cognitive transition. Inspired by that conference, this volume is the first collection where each content chapter presents a fully implemented, self-modifying simulation of some aspect of cognitive development. Previous collections have tended to discuss general approaches -- less than fully implemented models -- or non self-modifying models. Along with introductory and review chapters, this volume presents a set of truly "developmental" computational models -- a collection that can inform the interested researcher as well as form the basis for graduate-level courses.

Children think in a different way to adults. They also think differently at different ages. This book, originally published in 1984, studies the growth of those processes by means of which thinking evolves from infancy through childhood and adolescence into adulthood. It covers perception, memory, language and, above all, the development of mental ‘programmes’, or strategies, through which people structure and hence comprehend the information coming to them from their environment. The study of cognitive development has obvious educational implications. Development in the pre-school period, the appropriateness of schooling for levels of cognitive competence, and the significance of ageing are just some of the issues considered.

One of developmental psychology's central concerns is the identification of specific "milestones" which indicate what children are typically capable of doing at different ages. Work of this kind has a substantial impact on the way parents, educators, and service-oriented professionals deal with children; and, therefore one might expect that developmentalists would have come to some general agreement in regard to the ways they assess children's abilities. However, as this volume demonstrates, the field appears to suffer from a serious lack of consensus in this area. Based on the premise that identifying relevant issues is a necessary step toward progress, this book addresses a number of vital topics, such as: How could research into fundamental areas (such as the age at which children first acquire a sense of self or learn to reason transitively) repeatedly yield wildly diverse results? Why do experts who hold to radically different views appear to be so unruffled by this same divergence of professional opinion? and, Are there grounds for hope that this divergence of professional opinion is on the wane?

Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.

This integrative text spotlights what educators need to know about children's cognitive development across grade levels (PreK-12) and content areas. The book provides a concise introduction to developmental neuroscience and theories of learning. Chapters on general cognitive abilities probe such crucial questions as what children are capable of remembering at different ages, what explains differences in effort and persistence, and how intelligence and aptitudes relate to learning. Domain-specific chapters focus on the development of key academic skills in reading, writing, math, science, and history. Multiple influences on academic achievement and motivation are explored, including school, family, cultural, and socioeconomic factors. Each chapter concludes with clear implications for curriculum and instruction.

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.

Research on memory development has accumulated over the past few years. Given the number of relevant publications in the field, it becomes increasingly difficult to keep track of major advances in specific areas of memory development. This book illustrates 2 purposes: * to permit experts in the various subdomains of research in memory development to summarize recent findings concerning the respective roles of capacity, strategies, and knowledge in the acquisition of memory skills; and * to discuss cross-cutting topics such as the influence of individual differences, practical and educational implications, and the potential of longitudinal studies.

The aims of this book are to consider critically the major themes and findings within this growing social-cognitive developmental research, and to present a new theoretical framework for investigating children's social cognitive skills.
