We acquire concepts such as "atom," "force," "integer," and "democracy" long after we are born; these concepts are not part of the initial cognitive state of human beings. Other concepts like "object," "cause," or "agent" may be present early in infancy - if not innately. Processes of change occur throughout our conceptual development, which prompts two key questions: Which human concepts constitute innate, core knowledge? How do humans acquire new concepts, and how do these concepts change in development?

Core Knowledge and Conceptual Change provides a unique theoretical and empirical introduction to the study of conceptual development, documenting key advances in case studies, including ground-breaking science on human representations of language, objects, number, events, color, space, time, beliefs, and desires. Additionally, it explores how humans engage in moral reasoning and causal explanation: Are humans born good and tainted by an imperfect world, or do we need to teach children to be moral? Could a concept like "freedom" be woven into the human soul, or is it a historical invention, constructed over generations of humans? Written by an eminent list of contributors renowned in child development and cognitive science, this book delves widely, and deeply, into the cognitive tools available at birth that are repurposed, combined, and transformed to complex, abstract adult conceptual representations, and should be of interest to developmental psychologists, linguists, philosophers, and students of cognitive science.

David Barner, PhD, is a Professor of Psychology and Linguistics at the University of California, San Diego. Dr. Barner studies the origin of human language and thought by studying how they develop in children in diverse cultural and linguistic contexts. Andrew Scott Baron, PhD, is an Assistant Professor of Psychology at the University of British Columbia, Canada. Dr. Baron's research explores the nature of the human capacity to be prejudiced by examining infants' and young children's tendency to categorize others into social groups and to form positive and negative attitudes and beliefs about these groups.

"Core Knowledge and Conceptual Change addresses the deepest questions at the heart of cognitive science: How do humans come to know the world? What is innate, and how does conceptual change take place? The answers come from a who's who of developmental psychologists, examining language, number, moral reasoning, theory of mind, and beyond. The result is a dazzling array of insights, hot-off-the-press empirical findings, and further questions that set the research agenda for years to come. A must-read."

"This is an extraordinary collection of chapters focusing on some of the most central questions in cognitive science concerning the origins of concepts, the nature of conceptual change and ultimately what concepts themselves are. Taken together, these chapters offer an invaluable and comprehensive collection of essays that will be of great interest to the cognitive science community."

--Frank Keil, PhD, Charles C. and Dorothea S. Dilley Professor and Chair of Psychology, Yale University
