Updating the interlanguage hypothesis dating a nice guy
The more time that learners have to plan, the more target-like their production may be.
Thus, literate learners may produce much more target-like forms in a writing task for which they have 30 minutes to plan, than in conversation where they must produce language with almost no planning at all.
An interlanguage is idiosyncratically based on the learners' experiences with the L2.
It can "fossilize", or cease developing, in any of its developmental stages.
The most important psychological factor is usually regarded as attention to form, which is related to planning time.Social factors may include a change in register or the familiarity of interlocutors.In accordance with communication accommodation theory, learners may adapt their speech to either converge with, or diverge from, their interlocutor's usage.Free variation in the use of a language feature is usually taken as a sign that it has not been fully acquired.The learner is still trying to figure out what rules govern the use of alternate forms.
