Volume I is the first of two volumes that document the three components of the CHILDES Project. It is divided into two parts which provide an introduction to the use of computational tools for studying language learning. The first part is the CHAT manual, which describes the conventions and principles of CHAT transcription and recommends specific methods for data collection and digitization. The second part is the CLAN manual, which describes the uses of the editor, sonic CHAT, and the various analytic commands. The book will be useful for both novice and experienced users of the CHILDES tools, as well as instructors and students working with transcripts of child language.
Volume II describes in detail all of the corpora included in the CHILDES database. The conversational interactions in the corpora come from monolingual children and their caregivers and siblings, as well as bilingual children, older school-aged children, adult second-language learners, children with various types of language disabilities, and aphasic recovering from language loss. The database includes transcripts in 26 different languages.
The CD-ROM that accompanies these volumes includes the transcript files described in Volume II. It runs on both Windows and Macintosh platforms. For more information or updates to the files, visit the CHILDES website at http: //childes.psy.cmu.edu

This volume examines the conflicting factors that shape the content and form of grammatical rules in language usage. Speakers and addressees need to contend with these rules when expressing themselves and when trying to comprehend messages. For example, there are on-going competitions between the speaker's interests and the addressee's needs, or between constraints imposed by grammar and those imposed by online processing. These competitions influence a wide variety of systems, including case marking, agreement and word order, politeness forms, lexical choices, and the position of relative clauses. Chapters in the book analyse grammar and usage in adult language as well as first and second language acquisition, and the motivations that drive historical change. Several of the chapters seek explanations for the competitions involved, based on earlier accounts including the Competition Model, Natural Morphology, the functional-typological tradition, and Optimality Theory. The book will be of interest to linguists from a wide variety of backgrounds, particularly those interested in psycholinguistics, historical linguistics, philosophy of language, and language acquisition, from advanced undergraduate level upwards.

For nearly four centuries, our understanding of human development has been controlled by the debate between nativism and empiricism. Nowhere has the contrast between these apparent alternatives been sharper than in the study of language acquisition. However, as more is learned about the details of language learning, it is found that neither nativism nor empiricism provides guidance about the ways in which complexity arises from the interaction of simpler developmental forces. For example, the child's first guesses about word meanings arise from the interplay between parental guidance, the child's perceptual preferences, and neuronal support for information storage and retrieval. As soon as the shape of the child's lexicon emerges from these more basic forces, an exploration of "emergentism" as a new alternative to nativism and empiricism is ready to begin.
This book presents a series of emergentist accounts of language acquisition. Each case shows how a few simple, basic processes give rise tonew levels of language complexity. The aspects of language examined here include auditory representations, phonological and articulatory processes, lexical semantics, ambiguity processing, grammaticality judgment, and sentence comprehension. The approaches that are invoked to account formally for emergent patterns include neural network theory, dynamic systems, linguistic functionalism, construction grammar, optimality theory, and statistically-driven learning. The excitement of this work lies both in the discovery of new emergent patterns and in the integration of theoretical frameworks that can formalize the theory of emergentism.
