Why is it hard to learn a second language as an adult while the children may learn to speak more than one language more easily than adults do? If true, how can the language learning process be made easier and successful?

  • I've heard once that some theories disproved that, but I can't find anything so I'm starting to doubt about it...

    You might want to have a look at Bley-Vroman's 1990 paper, The Logical Problem of Foreign Language Learning, as something to start with.

I just spent one month in the United States with my two daughters, neither of which spoke English before. I will answer with anecdotal evidence in regard to the older of the two, she is five years old.

It seems to me that children have less rigidly established ideas about the world around them, and are willing to accept new names and new thought paradigms more readily than adults. For instance, when I look at a table it is for me "שולחן" and I have to translate that into "table". After one week in the US I was still translating "שולחן" to "table" every time I had to use the word. However, only in the last few days did the idea that the object with a flat surface and four legs is called "table" really sink in and come out naturally. Contrast with my daughter, who learned the word "bed" the first day in the US. The next day, speaking in our native language, she used the word "bed". For her, giving the object a new title was less an exercise in replacing an existing title but more an exercise in establishing a title - any title - for the object even though she already had a title for it. I noticed a similar phenomenon for grammar. She was not translating sentences, but rather learning them anew. Her idea of what a sentence "should be" was obviously less firmly established than my own.

Also, you might be interested in a related answer in reference to the elderly that I recently answered.


From toddlerhood to about four years of age, children acquire their first languages without much explicit instruction, simply by exposure to and attempts to communicate in the mother tongue. There are some significantly different theories regarding this fact, but the fact is universally acknowledged. See https://en.wikipedia.org/wiki/Language_acquisition.

What is more, the fact that children make mistakes that ambient proficient speakers don't make (e.g. for English, "gots" for "has," "goed" for "went," knocks the legs out from under the hypothesis that mimicry and reinforcement are sufficient to explain first language acquisition.

During the early years just mentioned, a child can pick up more than one language provided that said child has sufficient exposure to each language. However, after about six or seven years of age, second languages are learned rather than acquired. See http://www.best4future.com/blog/how-children-acquire-second-languages. In other words, the language must be taught methodically, even if part of the teaching is a period of immersion (using only the target language among speakers of the target language.
