Can we learn a second language as we learned our mother toungue?
We learn our mother tongue by association and by continued exposure to it, we hear our parents talk and we start to utter what we heard; our home environment was in some way our first language school. There we were developing all the skills needed to manage a language and to communicate , we did not have to write, study, rehearse grammatical rules or drill vocabulary cards, it just happened spontaneously.
The process that occurs when we learn our first language is discovering as we go along, as a child if we pointed or wanted to know a word, the information came straight from our parents, siblings or some other source like the media just to mention one.
Children can acquire another language naturally, without conscious learning as adults do, they are good imitators so for them pronunciation is not an issue, also they can figure rules by themselves; some children who have the opportunity to learn a second language use the same innate language learning strategy.
Scientific studies have explained that after the process of lateralization in a person´s brain is complete approximately at the age of 10, the chances of acquiring a second language is more challenging and difficult.
