Facts about learning SLA

Here's a fact!

Why is it important to understand second language acquisition?

Knowing the same language connects us to one another. We use language to share information, thoughts and ideas, and these viewpoints collectively create culture. Learning a second language connects you to a whole new group of people and their culture.

Second-language acquisition (SLA), second-language learning or 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 field of second-language acquisition is a subdiscipline of applied linguistics, but also receives research attention from a variety of other disciplines, such as psychology and education.

A central theme in SLA research is that of interlanguage, the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but that it is a complete language system in its own right, with its own systematic rules.

This interlanguage gradually develops as learners are exposed to the targeted language. The order in which learners acquire features of their new language stays remarkably constant, even for learners with different native languages and regardless of whether they have had language instruction.

However, languages that learners already know can have a significant influence on the process of learning a new one. This influence is known as language transfer.

The primary factor driving SLA appears to be the language input that learners receive. Learners become more advanced the longer they are immersed in the language they are learning and the more time they spend doing free voluntary reading. The input hypothesis developed by linguist Stephen Krashen theorizes that comprehensible input alone is necessary for second language acquisition.

Research on how exactly learners acquire a new language spans a number of different areas. Focus is directed toward providing proof of whether basic linguistic skills are innate (nature), acquired (nurture) or a combination of the two attributes.

Cognitive approaches to SLA research deal with the processes in the brain that underpin language acquisition, for example how paying attention to language affects the ability to learn it, or how language acquisition is related to short-term and long-term memory.

Individuals may also lose a language through a process called second-language attrition. This is often caused by lack of use or exposure to a language over time. The severity of attrition depends on a variety of factors including level of proficiency, age, social factors, and motivation at the time of acquisition. Finally, classroom research deals with the effect that language instruction has on acquisition. (This one is a good fact to know)

SLA can incorporate heritage language learning, but it does not usually incorporate bilingualism. Most SLA researchers see bilingualism as being the end result of learning a language, not the process itself, and see the term as referring to native-like fluency. Writers in fields such as education and psychology, however, often use bilingualism loosely to refer to all forms of multilingualism.

SLA is also not to be contrasted with the acquisition of a foreign language; rather, the learning of second languages and the learning of foreign languages involve the same fundamental processes in different situations.

The academic discipline of second-language acquisition is a subdiscipline of applied linguistics. It is broad-based and relatively new. As well as the various branches of linguistics, second-language acquisition is also closely related to psychology, cognitive psychology, and education.

To separate the academic discipline from the learning process itself, the terms second-language acquisition research, second-language studies, and second-language acquisition studies are also used.
