Part II focuses on comparisons across groups, addressing the theoretical, applied and methodological issues involved in such comparative work. This book will not only be of use to advanced undergraduate and postgraduate students, but also to any scholars wishing to learn more about a particular research method. It is suitable as a textbook in postgraduate programs in the fields of linguistics, education and psychology."

Language learning research aims to describe and fully explain how and why language learning takes place, but can fall short of its stated purpose. Systematic, rigorous research is needed if the growing field of language learning is to progress methodically. This book demonstrates and fully explains such a methodology. Given that research in language acquisition yields practical pedagogical implications, it is crucial that it is rigorous and accurate. This book offers a quantitative research methodology that relies on statistical analysis in order to make inferences and conclusions about language learning. Experimental research aims to understand differences between or within groups of learners under manipulated environments. It requires strict control of conditions, enabling interpretations with a low factor of error. Aek Phakiti provides step-by-step guidelines and underlying principles, epistemology and methodology, in a book that is essential for advanced students of language acquisition and language and education.

Language acquisition research is challenging—the intricate behavioral and cognitive foundations of speech are difficult to measure objectively. The audible components of speech, however, are quantifiable and thus provide crucial data. This practical guide synthesizes the authors’ decades of experience into a comprehensive set of tools that will allow students and early career researchers in the field to design and conduct rigorous studies that produce reliable and valid speech data and interpretations. The authors thoroughly review specific techniques for obtaining qualitative and quantitative speech data, including how to tailor the testing environments for optimal results. They explore observational tasks for collecting natural speech and experimental tasks for eliciting specific types of speech. Language comprehension tasks are also reviewed so researchers can study participants’ interpretations of speech and conceptualizations of grammar. Most tasks are oriented towards children, but special considerations for infants are also reviewed, as well as multilingual children. Chapters also provide strategies for transcribing and coding raw speech data into reliable data sets that can be scientifically analyzed. Furthermore, they investigate the intricacies of interpretation so that researchers can make empirically sound inferences from their data and avoid common pitfalls that can lead to unscientific conclusions.

Using Priming Methods in Second Language Research is an accessible introduction to the use of auditory, semantic, and syntactic priming methods for second language (L2) processing and acquisition research. It provides a guide for the use, design, and implementation of priming tasks and an overview of how to analyze and report priming research. Key principles about auditory, semantic, and syntactic priming are introduced, and issues for L2 researchers to consider when designing priming studies are pointed out. Empirical studies that have adopted priming methods are highlighted to illustrate the application of experimental techniques from psychology to L2 processing and acquisition research. Each chapter concludes with follow-up questions and activities that provide additional reinforcement of the chapter content, while the final chapter includes data sets that can be used to practice the statistical tests commonly used with priming data.

The present volume is a broad overview of methods and methodologies in linguistics, illustrated with examples from concrete research. It collects insights gained from a broad range of linguistic sub-disciplines, ranging from core disciplines to topics in cross-linguistic and language-internal diversity or to contributions towards language, space and society. Given its critical and innovative nature, the volume is a valuable source for students and researchers of a broad range of linguistic interests.

This introductory guide to language acquisition research is presented within the framework of Universal Grammar, a theory of the human faculty for language. The authors focus on two experimental techniques for assessing children's linguistic competence: the Elicited Production task, a production task, and the Truth Value Judgment task, a comprehension task. Their methodologies are designed to overcome the numerous obstacles to empirical investigation of children's language competence. They produce research results that are more reproducible and less likely to be dismissed as an artifact of improper experimental procedure. In the first section of the book, the authors examine the fundamental assumptions that guide research in this area; they present both a theory of linguistic competence and a model of language processing. In the following two sections, they discuss in detail their two experimental techniques.

Language addressed to children, or 'Baby Talk', became the subject of research interest thirty years ago. Since then, the linguistic environment of infants and toddlers has been widely studied. Input and Interaction in Language Acquisition is an up-to-date statement of the facts and controversies surrounding 'Baby Talk', its nature and likely effects. With contributions from leading linguists and psychologists, it explores language acquisition in different cultures and family contexts, in typical and atypical learners, and in second and foreign language learners. It is designed as a sequel to the now famous Talking to Children, edited by Catherine Snow and Charles Ferguson, and Professor Snow here provides an introduction, comparing issues of importance in the field today with the previous concerns of researchers.

Corpus research forms the backbone of research on children's language development. Leading researchers in the field present a survey on the history of data collection, different types of data, and the treatment of methodological problems. Morphologically and syntactically parsed corpora allow for the concise explorations of formal phenomena, the quick retrieval of errors, and reliability checks. New probabilistic and connectionist computations investigate how children integrate the multiple sources of information available in the input, and new statistical methods compute rates of acquisition as well as error rates dependent on sample size. Sample analyses show how multi-modal corpora are used to investigate the interaction of discourse and linguistic structure, how cross-linguistic generalizations for acquisition can be formulated and tested, and how individual variation can be explored. Finally, ways in which corpus research interacts with computational linguistics and experimental research are presented.
