How does a biologically-programmed language faculty interact with language experience in the acquisition of language across the world? Bringing together linguistic theory, language typology, and cross-linguistic experimental results from parallel studies of development in language acquisition, this book reports new research on the nature of the human competence for language acquisition. It investigates the acquisition of complex sentence formation through relativization -a fundamental component of language knowledge- through systematic, formally explicit, hypothesis-driven experimental studies from English, French and Tulu (in the US, Belgium and India). It demonstrates that across languages, the course of acquisition shares basic properties in keeping with universals of a language faculty, while at the same time, in all languages, specific relativization forms are achieved through development. The results show the power of an approach to the study of language acquisition which bridges linguistic theory of Universal Grammar with real-time creation of a specific language by the child.

Synthesizing decades of collective experience into a set of practical guidelines for students and budding researchers, the authors of this book introduce a systematic approach to generating, processing, and interpreting reliable and valid speech data. They review a variety of observational and experimental tasks that allow researchers to collect natural speech, elicit specific types of speech, and assess language comprehension. Guidelines for generating data sets by transcribing and coding raw speech data are also reviewed, as are special considerations for working with infants and multilingual children.
