Looking at the ways humans perceive, interpret, remember, and interact with events occurring in space, this book focuses on two aspects of spatial cognition: How does spatial cognition develop? What is the relation between spatial cognition and the brain? This book offers a unique opportunity to share the combined efforts of scientists from varied disciplines, including cognitive and developmental psychology, neuropsychology, behavioral neurology, and neurobiology in the process of interacting and exchanging ideas. Based on a conference held at the Neuroscience Conference Center of the Salk Institute for Biological Studies, this book explores current scientific trends seeking a biological basis for understanding the relationships among brain, mind, and behavior.

In a book with far-reaching implications, Edward S. Klima and Ursula Bellugi present a full exploration of a language in another mode--a language of the hands and of the eyes. They discuss the origin and development of American Sign Language, the internal structure of its basic units, the grammatical processes it employs, and its heightened use in poetry and wit. The authors draw on research, much of it by and with deaf people, to answer the crucial question of what is fundamental to language as language and what is determined by the mode (vocal or gestural) in which a language is produced.
