How children learn more than one language
Bilingual acquisition can take place in one of two ways:
1.     Simultaneous Acquisition occurs when a child is raised bilingually from birth, or when the second language is introduced before the age of three (10). Children learning two languages simultaneously go through the same developmental stages as children learning one language. While bilingual children may start talking slightly later than monolingual children, they still begin talking within the normal range (11). From the very beginning of language learning, simultaneous bilinguals seem to acquire two separate languages (10). Early on, they are able to differentiate their two languages and have been shown to switch languages according to their conversation partner (e.g. speak French to a French-speaking parent, then switch to English with an English-speaking parent) (12, 13).
2.     Sequential Acquisition occurs when a second language is introduced after the first language is well-established (generally after the age of three). Children may experience sequential acquisition if they immigrate to a country where a different language is spoken. Sequential learning may also occur if the child exclusively speaks his heritage language at home until he begins school, where instruction is offered in a different language.
A child who acquires a second language in this manner generally experiences the following (10):
  • initially, he may use his home language for a brief period.
  • he may go through a “Silent” or “Nonverbal” Period when he is first exposed to a second language. This can last from a few weeks to several months, and is most likely a time when the child builds his understanding of the language (14). Younger children usually remain in this phase longer than older children. Children may rely on using gestures in this period, and use few words in the second language.
  • he will begin to use short or imitative sentences. The child may use one-word labels or memorized phrases such as “I dunno” or “What’s this?”. These sentences are not constructed from the child’s own vocabulary or knowledge of the language. Rather, they are phrases he has heard and memorized.
  • eventually, he will begin to produce his own sentences. These sentences are not entirely memorized, and incorporate some of the child’s own newly-learned vocabulary. The child may use a “formula” at first when constructing sentences and insert his own word into a common phrase such as “I want…” or “I do….”. Eventually the child becomes more and more fluent, but continues to make grammatical mistakes or produce sentences that sound abbreviated because he is missing some grammatical rules (e.g. “I no want eat apple” instead of “I don’t want to eat an apple”). Some of the mistakes a child makes at this stage are due to the influence of his first language. But many of the mistakes are the same types of mistakes that monolingual children make when they learn that language.
