<p>In this groundbreaking book, Michael Tomasello presents a comprehensive usage-based theory of language acquisition. Drawing together a vast body of empirical research in cognitive science, linguistics, and developmental psychology, Tomasello demonstrates that we don't need a self-contained "language instinct" to explain how children learn language. Their linguistic ability is interwoven with other cognitive abilities.</p><p>Tomasello argues that the essence of language is its symbolic dimension, which rests on the uniquely human ability to comprehend intention. Grammar emerges as the speakers of a language create linguistic constructions out of recurring sequences of symbols; children pick up these patterns in the buzz of words they hear around them.</p><p>All theories of language acquisition assume these fundamental skills of intention-reading and pattern-finding. Some formal linguistic theories posit a second set of acquisition processes to connect somehow with an innate universal grammar. But these extra processes, Tomasello argues, are completely unnecessary--important to save a theory but not to explain the phenomenon.</p><p>For all its empirical weaknesses, Chomskian generative grammar has ruled the linguistic world for forty years. <i>Constructing a Language</i> offers a compellingly argued, psychologically sound new vision for the study of language acquisition. </p>
