Lexical Diversity and Language Development (eBook, PDF)

Quantification and Assessment

• Format: PDF

Produktbeschreibung

Vocabulary richness, including lexical diversity and use of rare words, has an important role in assessing proficiency, diagnosing progress and testing theory in the study of language development. This book reviews different methods for quantifying how vocabulary is deployed in spontaneous speech and writing, before introducing an alternative approach which can assess overall lexical diversity, measure morphology development and compare the development of different word classes. The new approach is illustrated by its application to first and second language learners.

Rezensionen

'This book represents a major contribution to the study of both lexical diversity and language development... [and] provides the most comprehensive and compelling study available to date of vocabulary measurement, including type-token ratios, number of different words, and word length. The innovative, empirically validated, and user-friendly measure of lexical diversity (VOCD - or simply D) that it proposes is based on deep understanding of mathematical models combined with rich background in language acquisition and language assessment. The culmination of fifteen years of cooperative research between David Malvern, Brian Richards, and their co-authors at the University of Reading, this study represents the best of inter-disciplinary research. In style, the book is both erudite and readable. It should be an invaluable source of reference for scholars and graduate-level students in general and psycho-linguistics, in first and second language acquisition, language education, and language pathology.' - Ruth A. Berman, Professor Emeritus, Department of Linguistics, Tel Aviv University

'David Malvern and his co-authors have developed a new and very promising approach to the study of lexical diversity and language development. Their statistical method is far more sophisticated than anything we have had in the past. This book will be of great interest to the developmental psycholinguistic community.' - Professor Jean Berko Gleason, Department of Psychology, Boston University
