What is it about the human mind that accounts for the fact that we can all speak and understand a language? Why can't other creatures do the same? And what does this tell us about the rest of human abilities? Recent dramatic discoveries in linguistics and psychology provide intriguing answers to these age-old mysteries. Along with the stunning advances in neuro-science and artificial intelligence, this research has breathed new life into the study of the mind. The central idea of this book is that our language ability is stored in the brain as a set of unconscious patterns, or a "mental grammar." How do children learn this grammar? Ray Jackendoff demonstrates that this remarkable feat involves a rich interweaving of nature and nurture: children come to the task of learning language equipped with an innate, genetically encoded "Universal Grammar" that provides the building blocks for all human languages. Patterns in the Mind emphasizes the grammatical commonalities across languages, both spoken and signed, and discusses the implications for our understanding of language acquisition and loss. Is the rest of human ability and experience like language? Jackendoff shows that indeed many other abilities are also supported by an innate brain specialization, among them vision, appreciation of music, and our ability to interact socially and culturally with other people. Thus the mechanisms of human language serve as a vehicle for understanding more generally "the way we are."
