Recent developments in our understanding of the way the brain works have altered dramatically our view of how it is possible for us to learn and use language - a feat that is still enormously beyond the capacity of any computer in existence or even on the drawing board. Donald Loritz describes the history of the discovery that language is controlled by the brain, and thus somehow located in it, and the subsequent efforts of scientists in many areas - linguistics, psychology, neurology, computer science, and the new field at their intersection, cognitive science - to understand what language is, how the brain "contains" it, and how both language and this complex brain could have evolved. While one can easily find computer-generated cross-sectioned pictures of the brain and its use of language, such pictures do not get down to the level of networks of individual brain cells (neurons), and how such networks are actually capable of learning and storing information like the sounds and meanings of words and the patterns of understandable sentences. Loritz explains the basic properties of the brain and neuron networks, using lay language or terms that he carefully teaches the reader, so that these mysterious processes of neural information storage and access can be understood. He does so using a mathematical model of brain function called Adaptive Resonance Theory, a theory developed by Stephen Grossberg, and applying this theory to what we know about human language - not language as grammarians conceive it, but language as it is really spoken and comprehended. He takes this information about language from recent well-documented research on child language, the signed language of the deaf, and the language of people with brain damage, as well sa from normal speakers. Loritz's book is certain to provoke controversy, as it contradicts many of the ideas propounded by another very popular writer on brain and language, Steven Pinker. Unlike Pinker, Loritz argues that language has little if any innate component, and is something that our brains are well-equipped to learn.

Recent studies of vocal development in infants have shed new light on old questions of how the speech capacity is founded and how it may have evolved in the human species. Vocalizations in the very first months of life appear to provide previously unrecognized clues to the earliest steps in the process by which language came to exist and the processes by which communicative disorders arise. Perhaps the most interesting sounds made by infants are the uniquely human 'protophones' (loosely, 'babbling'), the precursors to speech. Kimbrough Oller argues that these are most profitably interpreted in the context of a new infrastructural model of speech. The model details the manner in which well-formed speech units are constructed, and it reveals how infant vocalizations mature through the first months of life by increasingly adhering to the rules of well-formed speech. He lays out many advantages of an infrastructural approach. Infrastructural interpretation illuminates the significance of vocal stages, and highlights clinically significant deviations, such as the previously unnoticed delays in vocal development that occur in deaf infants. An infrastructural approach also specifies potential paths of evolution for vocal communicative systems. Infrastructural properties and principles of potential communicative systems prove to be organized according to a natural logic--some properties and principles naturally presuppose others. Consequently some paths of evolution are likely while others can be ruled out. An infrastructural analysis also provides a stable basis for comparisons across species, comparisons that show how human vocal capabilities outstrip those of their primate relatives even during the first months of human infancy. The Emergence of the Speech Capacity will challenge psychologists, linguists, speech pathologists, and primatologists alike to rethink the ways they categorize and describe communication. Oller's infraphonological model permits provocative reconceptualizations of the ways infant vocalizations progress systematically toward speech, insightful comparisons between speech and the vocal systems of other species, and fruitful speculations about the origins of language.

This volume, the sixth in the Vancouver series based on an annual conference at Simon Fraser University, collects papers that discuss the evidence and arguments regarding the inheritability and innateness of grammars. The evidence - which ranges from babies who are just beginning to learn the properties of their native language, to language-impaired adults who will never learn it - converges to show that whole precursors of language exist in other creatures, the abilities necessary for constructing fully fledged grammars are part of the biological endowment of human beings.
