Most human beings grow up speaking more than one language; a lot of us also acquire an additional language or languages other than our mother tongue. This Element in the Second Language Acquisition series investigates the human capacity to learn additional languages later in life and introduces the seminal processes involved in this acquisition. The authors discuss how to analyze learner data and what the findings tell us about language learning; critically assessing a leading theory of how adults learn a second language: Generative SLA. This theory describes both universal innate knowledge and individual experiences as crucial for language acquisition. This Element makes the relevant connections between first and second language acquisition and explores whether they are fundamentally similar processes. Slabakova et al. provide fascinating pedagogical questions that encourage students and teachers to reflect upon the experiences of second language learners.
This Element provides an overview of research considering variables deemed to impact bilingual language acquisition, and highlights research outcomes from a variety of disciplines. An exploratory study takes into account these variables and examines the language acquisition of adult Spanish-English bilinguals across a range of domains in their two languages. The results demonstrate that the highly interactive nature of bilingual speakers' languages is in line with a holistic view of the dynamic, interdependent nature of bilingualism as described by usage-based theories and dynamic systems theories, and by the conceptualization of bilingual language from a Dynamic Interactive Processing Perspective.
This Cambridge Element examines the role and nature of focus on form in second language acquisition. An overall assessment of the role of instruction and the nature of language is provided. Instruction might have a facilitative role in the rate of acquisition. The Element briefly reviews empirical research examining the relative effects of different types of focus on form and presents some of the key implications for second language learning and teaching. An effective focus on form type is one that is input and meaning oriented. Manipulating input to facilitate language processing and form-meaning connections might enhance second language acquisition.
It is a well-known fact that some adult second language learners learn more rapidly and/or to a higher level of proficiency than others. Some of these individual differences have been linked to differences in cognitive and perceptual abilities under the umbrella term of 'language aptitude'. The notion of language aptitude has undergone recent developments, one of which is the proposal that language aptitude includes cognitive abilities that involve implicit processes and that are advantageous in learning a language without awareness. This Element defines implicit language aptitude, examines tasks that can be used to measure implicit language aptitude, and provides an overview of relevant research in this area.
This Element in the Cambridge Elements in Second Language Acquisition series examines the role of interaction in Second Language Acquisition research, with a focus on the cognitive interactionist approach. The Element describes the major branches of the field, considering the importance of conversational interaction in both the cognitive interactionist framework as well as in sociocultural approaches to second language learning. The authors discuss the key concepts of the framework, including input, negotiation for meaning, corrective feedback, and output. The key readings in the field and the emphases of current and future research are explained. Finally, the authors describe the pedagogical implications that the cognitive interactionist approach has had on the teaching of second languages.
