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.
v. t. e. Second-language acquisition (SLA), sometimes called second-language learning —otherwise referred to as L2 (language 2) acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process.
The interaction hypothesis is a theory of second-language acquisition which states that the development of language proficiency is promoted by face-to-face interaction and communication. [1] Its main focus is on the role of input, interaction, and output in second language acquisition. [2] It posits that the level of language that a learner is ...
e. Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language. In other words, it is how human beings gain the ability to be aware of language, to understand it, and to produce and use words and sentences to communicate. Language acquisition involves structures, rules, and representation.
Input hypothesis. The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five ...
Approach to language acquisition research has focused on three areas, namely the cognitive approach to language acquisition or the developmental cognitive theory of Jean Piaget, the information processing approach or the information processing model of Brian MacWhinney and Elizabeth Bates (the competition model), and the social interactionist approach or social interaction model of Lev ...
Processability theory (PT) is a cognitive approach to second language acquisition that seeks to explain developmental schedules as well as learner variation. It is based on Levelt’s (1989) approach to language generation and is formally operationalized using Lexical-Functional Grammar (Bresnan 2001). PT’s core assumption is that learners ...
Acculturation model. In second-language acquisition, the acculturation model is a theory proposed by John Schumann to describe the acquisition process of a second language (L2) by members of ethnic minorities [1] that typically include immigrants, migrant workers, or the children of such groups. [2] This acquisition process takes place in ...
