This book is a practical guide to building computational models of high-level cognitive processes and systems. High-level processes are those central cognitive processes involved in thinking, reasoning, planning, and so on. These processes appear to share representational and processing requirements, and it is for this reason that they are considered together in this text. The book is divided into three parts. Part I considers foundational and background issues. Part II provides a series of case studies spanning a range of cognitive domains. Part III reflects upon issues raised by the case studies. Teachers of cognitive modeling may use material from Part I to structure lectures and practical sessions, with chapters in Part II forming the basis of in-depth student projects. All models discussed in this book are developed within the COGENT environments. COGENT provides a graphical interface in which models may be sketched as "box and arrow" diagrams and is both a useful teaching tool and a productive research tool. As such, this book is designed to be of use to both students of cognitive modeling and active researchers. For students, the book provides essential background material plus an extensive set of example models, exercises and project material. Researchers of both symbolic and connectionist persuasions will find the book of interest for its approach to cognitive modeling, which emphasizes methodological issues. They will also find that the COGENT environment itself has much to offer.

"The Ball" takes us to the farthest reaches of the globe and the deepest recesses of our ancient past to answer a question asked by every child on Earth: Why do we play ball? Inspired by the curiosity of his sports-obsessed 8-year-old son, anthropologist John Fox sets off on a global adventure to explore the untold history of our favorite ball games, investigate their origins and evolutionary tracks, and discern how one of humanity's simplest inventions - the humble, ubiquitous ball - has staked an unrivaled claim on our history, our passions, our money, and our lives. From the jungles of Mexico to the farm country of Ohio, from the courts of the ancient Pharaohs to the virtual playing fields of Second Life, Rolling Heads and Pigskins puts us center court for the gritty, ritualistic, violent, bizarre, primal drama of ball games as we've played them across the centuries. Part history, part travelogue, and part sportscast, "The Ball" spins tales of the ball itself as actor and instigator, a player who taps our human urge to hit, kick, throw, and tackle. In the end, "The Ball" removes us from the scandals, corruption, and commercialism of today's sports to uncover the true reasons we play ball, helping us reclaim our fundamental human connection to the games we love.
