Acquisition and age

Is there a relationship between age and LA?

Stern (1970) suggested a second language teaching method on the basis of FLA.

1. Practice 2. Imitate 3. Practice sounds then word then sentences 4. Listen then understand 5. Reading and writing are advanced stages of learning language 6. Do not translate 7. Use language and not grammar

 First and second language acquisition in children (C1 –C2)  Second language acquisition in children and adults (C2 – A2)  First language acquisition in children and second language acquisition in adults (C1 – A2)

Manipulate language variable (C1-C2) Manipulate the differences between children and adults (C2 – A2) Manipulates both variables (C1-A2)

 It claims that there is a biological timetable  Neurobiological development affects second language success  Hemispheric lateralization and right hemispheric paeticipation

 What is the age of authentic pronunciation ?  Is pronunciation of language the sole criterion fro acquisition?
