Interface position

Article summary

The interface position is a concept in second language acquisition that describes the various possible theoretical relationships between implicit and explicit knowledge in the mind of a second language learner. Tacit knowledge is language knowledge that learners possess intuitively but are not able to put into words; explicit knowledge is language knowledge that learners possess and are also able to verbalize. For example, native speakers of Spanish intuitively know how to conjugate verbs (implicit knowledge), but may be unable to articulate how these grammatical rules work. Conversely, a non-native student of Spanish may be able to explain how Spanish verbs are conjugated (explicit knowledge), but may not yet be able to use these verbs in naturalistic, fluent speech. The nature of the relationship between these two types of knowledge in second language learners has received considerable attention in second language acquisition research. There are three basic positions in the interface position: the no-interface position, the strong-interface position, and various weak-interface positions. The no-interface position states that there is no relationship between these two types of knowledge; in other words, knowledge that has been learned explicitly can never become fast, automatic language knowledge.…
