Individual Differences in Language Ability and Language Behavior is a collection of papers that discusses differences at the center of the study of language, specifically, on the various dimensions of linguistic ability and behavior along which individuals can differ from each other. Papers also review the development of techniques that measure these dimensions in relation to biological, psychological, and cultural parameters. Some papers review individual differences in language study in terms of different perspectives: that of a psychometrician's, of an individualistic's vantage point, and of a psycholinguistic's. Other papers discuss how each individual accesses, uses, and judges his language through fluency, biases, spatial principles, or a linguistic-phonetic mode. Several papers examine individual differences in language acquisition, such as "profile analysis," strategies in acquisition of sounds, second language learning, and duplication of adult language system. A group of papers addresses the biological aspects of language variation. These biological aspects include selective disorders of syntax (agrammatism), selective disorders of lexical retrieval (anomia), and cerebral lateralization effects in language processing. Certain papers explain individual differences in languages using sociolinguistic analysis. The collection is well suited for linguists, ethnologists, psychologists, and researchers whose works involve linguistics, learning, communications, and syntax.

The scope of individual learner differences is broad, yet there is no current, comprehensive, and unified volume that provides an overview of the considerable amount of research conducted on various language learner differences, until now.

Understanding the way in which learners differ from one another is of fundamental concern to those involved in second-language acquisition, either as researchers or teachers. This account is the first to review at book length the important research into differences, considering matters such as aptitude, motivation, learner strategies, personality and interaction between learner characteristics and types of instruction.

Topics include the linguist's attitude, the work session and the roles of native speakers.

This volume corrects the relative neglect in Second Language Acquisition studies of the quantitative study of language variation and provides insights into such issues as language transfer, acquisition through exposure, language universals, learner's age and so forth. These studies bolster the idea that a full account of SLA development (and, hence, a “theory of SLA”) must be built on not only detailed accounts of interlanguage data but also on a wide appeal to factors which govern the psycholinguistic bases of SLA. An important addition to the volume is a comprehensive guide to both the DOS and Macintosh versions of the VARBRUL statistical program used by variationists.

How do we manage to speak and understand language? How do children acquire these skills and how does the brain support them? This book provides a fascinating personal history of the men and women whose intelligence, brilliant insights, fads, fallacies, cooperations, and rivalries created the discipline we call psycholinguistics.

The Handbook of Second Language Acquisition presents an integrated discussion of key, and sometimes controversial, issues in second language acquisition research. Discusses the biological and cognitive underpinnings of SLA, mechanisms, processes, and constraints on SLA, the level of ultimate attainment, research methods, and the status of SLA as a cognitive science. Includes contributions from twenty-seven of the world's leading scholars. Provides an invaluable resource for all students and scholars of human cognition, including those in linguistics, psychology, applied linguistics, ESL, foreign languages, and cognitive science.

The contributions to this volume reflect the state of the art in the renewed discussion on the origin of language. Some of the most important specialists in the field - life scientists and linguists - primarily examine two aspects of the question: the origin of the language faculty and the evolution of the first language. At stake is the relation between nature and culture and between universality and historical particularity as well as cognition, communication, and the very essence of language.

Children with Specific Language Impairment covers all aspects of SLI, including its history, possible genetic and neurobiological origins, and clinical and educational practice.
