The first book-length treatment of its type, Ultimate Attainment in Second Language Acquisition is a case study with a solid theoretical grounding that examines the language of an immigrant learner of English, and thereby presents a much needed understanding of the linguistic competence of second language speakers. Based on longitudinal data collected over a period of 16 years, this clear and accessible presentation is well-grounded in linguistic theory and in second language acquisition research issues. Author Donna Lardiere presents the narrative of Patty, an adult Chinese immigrant learner of English, who achieves native-like proficiency in some areas of her English idiolect, although reaches a plateau in her language acquisition, known as the concept of fossilization. By addressing this concept, a central idea in second language acquisition research, Lardiere fills a void in existing literature. Individual chapters focus on Patty’s end state knowledge of grammatical areas of finiteness, past-tense marking, word order, wh-movement and relativization, passivization, number marking, and use of determiners. Important topics discussed throughout the book include: *learner variability in production; *case study methodology; *the roles of motivation and prior language (L1) knowledge; and *sensitivity to input in circumscribing ultimate attainment in adult second language acquisition. Ultimate Attainment in Second Language Acquisition is intended for anyone whose research is in the areas of second language acquisition, language acquisition, theoretical, applied, or developmental linguistics. It is also appropriate for graduate level students of TESOL and teachers who work with more advanced learners of foreign languages.

An introduction to the key questions that drive the field of L2 acquisition research, including its historical foundations.

Research on second language acquisition (SLA) has identified language aptitude and age of onset (AO), i.e., the age at which learners are first meaningfully exposed to the L2, as robust predictors of rate of classroom language learning and level of ultimate L2 attainment in naturalistic settings, respectively. It is not surprising, therefore, that recent years have witnessed a surge of interest in the combination of age and aptitude as a powerful explanatory factor in SLA, and central to a viable SLA theory. The chapters in this volume provide new studies and reviews of research findings on age effects, bilingualism effects, maturational constraints and sensitive periods in SLA, the sub-components of language aptitude and the development of new aptitude measures, the influence of AO and aptitude in combination on SLA, aptitude-treatment interactions, and the implications of the research findings for language education policy and tailored language instruction.

What is language and how can we investigate its acquisition by children or adults? What perspectives exist from which to view acquisition? What internal constraints and external factors shape acquisition? What are the properties of interlanguage systems? This comprehensive 31-chapter handbook is an authoritative survey of second language acquisition (SLA). Its multi-perspective synopsis on recent developments in SLA research provides significant contributions by established experts and widely recognized younger talent. It covers cutting edge and emerging areas of enquiry not treated elsewhere in a single handbook, including third language acquisition, electronic communication, incomplete first language acquisition, alphabetic literacy and SLA, affect and the brain, discourse and identity. Written to be accessible to newcomers as well as experienced scholars of SLA, the Handbook is organised into six thematic sections, each with an editor-written introduction.
