How Can You Tell the Age of a Baby Rabbit

Whatever adult who has attempted to learn a foreign linguistic communication can attest to how difficult and confusing it tin can exist. So when a three-yr-sometime growing up in a bilingual household inserts Spanish words into his English language sentences, conventional wisdom assumes that he is disruptive the two languages.

Research shows that this is not the case.

In fact, early childhood is the best possible time to learn a second language. Children who experience two languages from nascency typically go native speakers of both, while adults oft struggle with 2d language learning and rarely achieve native-like fluency.

Only the question remains: is information technology confusing for babies to larn 2 languages simultaneously?

When exercise babies larn linguistic communication?

Research shows babies brainstorm to learn language sounds before they're even born. In the womb, a mother's voice is one of the well-nigh prominent sounds an unborn baby hears. By the time they're born, newborns can not only tell the difference betwixt their female parent's language and another language, but also show a capability of distinguishing between languages.

Linguistic communication learning depends on the processing of sounds. All the globe's languages put together comprise nigh 800 or so sounds. Each language uses just about 40 language sounds, or "phonemes," which distinguish one language from another.

At birth, the baby brain has an unusual gift: it can tell the difference between all 800 sounds. This means that at this stage infants can larn whatever language that they're exposed to. Gradually babies effigy out which sounds they are hearing the about.

Between six and 12 months, infants who abound upwards in monolingual households go more specialized in the subset of sounds in their native language. In other words, they go "native language specialists." And, by their first birthdays, monolingual infants brainstorm to lose their ability to hear the differences between foreign language sounds.

Studying babe brains

What most those babies who hear two languages from birth? Can a baby brain specialize in 2 languages? If so, how is this process different so specializing in a single language?

Knowing how the infant brain learns 1 versus 2 languages is important for agreement the developmental milestones in learning to speak. For instance, parents of bilingual children oftentimes wonder what is and isn't typical or expected, or how their kid volition differ from those children who are learning a single language.

My collaborators and I recently studied the brain processing of language sounds in eleven-month-old babies from monolingual (English only) and bilingual (Spanish-English language) homes. We used a completely noninvasive technology called magnetoencephalography (1000000), which precisely pinpointed the timing and the location of activity in the brain as the babies listened to Spanish and English language syllables.

We found some key differences between infants raised in monolingual versus bilingual homes.

At 11 months of age, just before most babies begin to say their starting time words, the brain recordings revealed that:

• Babies from monolingual English households are specialized to process the sounds of English, and not the sounds of Spanish, an unfamiliar language

• Babies from bilingual Spanish-English households are specialized to process the sounds of both languages, Castilian and English language.

Here'south a video summarizing our study.

Our findings evidence that babies' brains go tuned to whatever language or languages they hear from their caregivers. A monolingual brain becomes tuned to the sounds of one linguistic communication, and a bilingual encephalon becomes tuned to the sounds of two languages. By 11 months of age, the activity in the baby brain reflects the language or languages that they have been exposed to.

Is it OK to learn 2 languages?

This has important implications. Parents of monolingual and bilingual children alike are eager for their niggling ones to utter the outset words. It'due south an exciting time to learn more than about what the baby is thinking. However, a common business organization, peculiarly for bilingual parents, is that their child is not learning fast enough.

We constitute that the bilingual babies showed an equally stiff brain response to English language sounds as the monolingual babies. This suggests that bilingual babies were learning English language at the same rate as the monolingual babies.

Parents of bilingual children as well worry that their children will non know every bit many words as children who are raised with one linguistic communication.

Bilingualism does not crusade defoliation. jakeliefer, CC By

To some extent, this concern is valid. Bilingual infants split their time betwixt ii languages, and thus, on average, hear fewer words in each. However, studies consistently show that bilingual children practise not lag backside when both languages are considered.

Vocabulary sizes of bilingual children, when combined across both languages, take been found to be equal to or greater than those of monolingual children.

Another common concern is that bilingualism causes confusion. Office of this concern arises due to "code switching," a speaking behavior in which bilinguals combine both languages.

For example, my 4-year-old son, who speaks English, Spanish, and Slovene, goes every bit far every bit using the Slovene endings on Spanish and English words. Research shows bilingual children code-switch because bilingual adults around them do too. Code-switching in bilingual adults and children is dominion-governed, not haphazard.

Unlike monolingual children, bilingual children have some other linguistic communication from which they can hands borrow if they can't quickly recollect the appropriate give-and-take in one language. Even two-yr-olds modulate their language to match the language used by their interlocutor.

Researchers have shown code switching to be part of a bilingual child'due south normal language development. And information technology could even exist the beginning of what gives them the extra cerebral prowess known every bit the "bilingual reward."

Bilingual kids are at an advantage

The good news is young children all effectually the world can and do acquire two languages simultaneously. In fact, in many parts of the world, being bilingual is the norm rather than an exception.

It is now understood that the constant need to shift attending between languages leads to several cognitive advantages. Enquiry has constitute that bilingual adults and children bear witness an improved executive functioning of the encephalon – that is, they are able to shift attention, switch between tasks and solve problems more easily. Bilinguals have also been plant to take increased metalinguistic skills (the ability to retrieve virtually language per se, and sympathise how it works). There is evidence that beingness bilingual makes the learning of a third language easier. Farther, the accumulating effect of dual language feel is thought to translate into protective effects against cerebral pass up with aging and the onset of Alzheimer's disease.

So, if yous want your child to know more than than 1 linguistic communication, information technology's best to start at an early historic period, before she even starts speaking her first language. Information technology won't confuse your child, and it could even give her a boost in other forms of cognition.
