This book examines a key issue in current cognitive theories - the nature of representation. Each chapter is characterized by attempts to frame hot topics in cognitive development within the landscape of current developmental theorizing and the past legacy of genetic epistemology. The chapters address four questions that are fundamental to any developmental line of inquiry: How should we represent the workings and contents of the mind? How does the child construct mental models during the course of development? What are the origins of these models? and What accounts for the novelties that are the products and producers of developmental change? These questions are situated in a historical context, Piagetian theory, and contemporary researchers attempt to trace how they draw upon, depart from, and transform the Piagetian legacy to revisit classic issues such as the child's awareness of the workings of mental life, the child's ability to represent the world, and the child's growing ability to process and learn from experience. The theoretical perspectives covered include constructivism, connectionism, theory-theory, information processing, dynamical systems, and social constructivist approaches. The research areas span imitation, mathematical reasoning, biological knowledge, language development, and theory of mind. Written by major contributors to the field, this work will be of interest to students and researchers wanting a brief but in-depth overview of the contemporary field of cognitive development.

Piaget's Legacy

Conceptual Development

Essentialism is the idea that certain categories, such as "dog," "man," or "intelligence," have an underlying reality or true nature that gives objects their identity. Where does this idea come from? In this book, Susan Gelman argues that essentialism is an early cognitive bias. Young children's concepts reflect a deep commitment to essentialism, and this commitment leads children to look beyond the obvious in many converging ways: when learning words, generalizing knowledge to new category members, reasoning about the insides of things, contemplating the role of nature versus nurture, and constructing causal explanations. Gelman argues against the standard view of children as concrete or focused on the obvious, instead claiming that children have an early, powerful tendency to search for hidden, non-obvious features of things. She also attacks claims that children build up their knowledge of the world based on simple, associative learning strategies, arguing that children's concepts are embedded in rich folk theories. Parents don't explicitly teach children to essentialize; instead, during the preschool years, children spontaneously construct concepts and beliefs that reflect an essentialist bias. Essentialist accounts have been offered, in one form or another, for thousands of years, extending back at least to Aristotle and Plato. Yet this book is the first to address the issues surrounding essentialism from a psychological perspective. Gelman synthesizes over 15 years of empirical research on essentialism into a unified framework and explores the broader lessons that the research imparts concerning, among other things, human concepts, children's thinking, and the ways in which language influences thought. This volume will appeal to developmental, cognitive, and social psychologists, as well as to scholars in cognitive science and philosophy.
