The immense growth of research on implicit and explicit memory is making it difficult to keep up with new methods and findings, to gauge the implications of new discoveries, and to ferret out new directions in research and theory development. The present volume provides a status report of work on implicit and explicit memory in the three areas that have contributed the bulk of what is known about this domain -- cognitive psychology, lifespan developmental psychology, and neuropsychology. Highlighting developments in methods, critical findings, and theoretical positions, this volume outlines promising new research directions. By so doing, it provides the reader with a multi-disciplinary perspective on implicit and explicit memory, and thereby enables a cross- fertilization of ideas and research.The chapters that make up this volume were written by experts on the topic of implicit and explicit memory. These contributors were asked to write for a broad audience -- for their colleagues from allied disciplines, for new researchers, for advanced undergraduate and graduate students -- to help them gain a comprehensive overview of the mushrooming research on this topic, grasp the most fundamental empirical and theoretical issues, and focus on new research directions.
