Paul Pimsleur was a French-American linguist and scholar in the field of applied linguistics. He developed the Pimsleur language learning system, which, along with his many publications, had a significant effect upon theories of language learning and teaching. Pimsleur Language Programs is an American language learning company that develops and publishes courses based on the Pimsleur Method.
A second language (L2) is a language spoken in addition to one's first language (L1). A second language may be a neighbouring language, another language of the speaker's home country, or a foreign language. A speaker's dominant language, which is the language a speaker uses most or is most comfortable with, is not necessarily the speaker's first language. For example, the Canadian census defines first language for its purposes as "the first language learned in childhood and still spoken", recognizing that for some, the earliest language may be lost, a process known as language attrition. This can happen when young children start school or move to a new language environment.
Second-language acquisition (SLA), sometimes called second-language learning — otherwise referred to as L2acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education.
Language learning aptitude refers to the "prediction of how well, relative to other individuals, an individual can learn a foreign language in a given amount of time and under given conditions". Foreign language aptitude itself has been defined as a set of cognitive abilities which predicts L2 learning rate, or how fast learners can increase their proficiency in a second or foreign language, and L2 ultimate attainment, or how close learners will get to being able to communicate like a native in a second or foreign language, both in classroom and real-world situations. Understanding aptitude is crucial for a complete picture of the process of second language acquisition. Knowledge about language aptitude has profound impacts in the field of Applied Linguistics, particularly in Second Language Acquisition (SLA) theory and in the practice of teaching and learning languages.
The generative approach to second language (L2) acquisition (SLA) is a cognitive based theory of SLA that applies theoretical insights developed from within generative linguistics to investigate how second languages and dialects are acquired and lost by individuals learning naturalistically or with formal instruction in foreign, second language and lingua franca settings. Central to generative linguistics is the concept of Universal Grammar (UG), a part of an innate, biologically endowed language faculty which refers to knowledge alleged to be common to all human languages. UG includes both invariant principles as well as parameters that allow for variation which place limitations on the form and operations of grammar. Subsequently, research within the Generative Second-Language Acquisition (GenSLA) tradition describes and explains SLA by probing the interplay between Universal Grammar, knowledge of one's native language and input from the target language. Research is conducted in syntax, phonology, morphology, phonetics, semantics, and has some relevant applications to pragmatics.
Kathleen Bardovi-Harlig is an American linguist. She is currently Provost Professor and ESL Coordinator at Indiana University (Bloomington).
The critical period hypothesis or sensitive period hypothesis claims that there is an ideal time window of brain development to acquire language in a linguistically rich environment, after which further language acquisition becomes much more difficult and effortful. It is the subject of a long-standing debate in linguistics and language acquisition over the extent to which the ability to acquire language is biologically linked to age. The critical period hypothesis was first proposed by Montreal neurologist Wilder Penfield and co-author Lamar Roberts in their 1959 book Speech and Brain Mechanisms, and was popularized by Eric Lenneberg in 1967 with Biological Foundations of Language.
Martha Young-Scholten is a linguist specialising in the phonology and syntax of second language acquisition (SLA).
Anne Vainikka was a Finnish-American linguist specialising in the syntax of Finnish and in the syntax of second language acquisition (SLA).
Vivian James Cook was a British linguist who was Emeritus Professor of Applied Linguistics at Newcastle University. He was known for his work on second-language acquisition and second-language teaching, and for writing textbooks and popular books about linguistics. He worked on a number of topics such as bilingualism, EFL, first-language acquisition, second-language teaching, linguistics, and the English writing system. He published more than 20 books and 100 papers. He was founder and first President of the European Second Language Association (EuroSLA), and co-founder of the Oxford University Press journal Writing Systems Research. He died in December 2021, at the age of 81.
The main purpose of theories of second-language acquisition (SLA) is to shed light on how people who already know one language learn a second language. The field of second-language acquisition involves various contributions, such as linguistics, sociolinguistics, psychology, cognitive science, neuroscience, and education. These multiple fields in second-language acquisition can be grouped as four major research strands: (a) linguistic dimensions of SLA, (b) cognitive dimensions of SLA, (c) socio-cultural dimensions of SLA, and (d) instructional dimensions of SLA. While the orientation of each research strand is distinct, they are in common in that they can guide us to find helpful condition to facilitate successful language learning. Acknowledging the contributions of each perspective and the interdisciplinarity between each field, more and more second language researchers are now trying to have a bigger lens on examining the complexities of second language acquisition.
The following outline is provided as an overview of and topical guide to second-language acquisition:
Complex Dynamic Systems Theory in the field of linguistics is a perspective and approach to the study of second, third and additional language acquisition. The general term Complex Dynamic Systems Theory was recommended by Kees de Bot to refer to both Complexity theory and Dynamic systems theory.
Marjolijn Verspoor is a Dutch linguist. She is a professor of English language and English as a second language at the University of Groningen, Netherlands. She is known for her work on Complex Dynamic Systems Theory and the application of dynamical systems theory to study second language development. Her interest is also in second language writing.
Diane Larsen-Freeman is an American linguist. She is currently a Professor Emerita in Education and in Linguistics at the University of Michigan in Ann Arbor, Michigan. An applied linguist, known for her work in second language acquisition, English as a second or foreign language, language teaching methods, teacher education, and English grammar, she is renowned for her work on the complex/dynamic systems approach to second language development.
