A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? We donât understand the way language, thinking and planning develop very well. Now scientists are using new technology to âseeâ into childrenâs brains. And they seem to be discovering new information about the way a babyâs brain develops.
A study in 2010 showed that the experiences a child has in their first few years affects the development of the brain. It showed that children who received more attention seemed to have higher IQs. The brain of a newborn baby has nearly a hundred billion neurons. This is the same number as an adultâs brain. As they grow, a baby receives information through the senses of sight, hearing, smell, taste and touch. This information creates connections between different parts of the brain. At the age of three, there are a hundred trillion connections.
One experiment looked at images of babiesâ brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern âA-B-Bâ. Another sequence was mu-ba-ge. This is the pattern âA-B-Câ. The images showed that the part of the brain responsible for speech seemed more active during âA-B-Bâ patterns. This probably shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: âJohn killed the bearâ is very different from âThe bear killed John.â So, it looks like that babies learn grammatical rules from the beginning of life.
Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audio books or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that it is possible that the second group could recognize different sounds, however the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.
