VOICE TWO: Another study suggests that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems. American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between nineteen eighty-four and nineteen eighty-seven. At birth, each child weighed fewer than two thousand grams. The boys and girls had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests in their homes. Their test results were compared with those of other children their age. The study found that the young people with low birth weight often had more problems with movement skills than others. These problems were more common among males, those with injured nerve tissue in the brain and those who had been connected to oxygen supplies for days as a baby. VOICE ONE: Experts say the first three years of a child's life is the most intensive period of language and speech development. This is the time when the brain is developing. Language and communication skills are believed to develop best in an environment that is rich with sounds and sights. Also, the child should repeatedly hear the speech and language of other people. The National Institutes of Health says evidence suggests there are important periods of speech and language development in children. This means the brain is best able to learn a language during this period. Officials say the ability to learn a language will be more difficult if these periods pass without early contact with a language. VOICE TWO: The first signs of communication happen during the first few days of life when a baby learns that crying will bring food and attention. Research shows that most children recognize the general sounds of their native language by six months of age. At that time, a baby also usually begins to make sounds. These sounds become a kind of nonsense speech over time. By the end of the first year, most children are able to say a few simple words. But they may not understand the meaning of their words. By eighteen months of age, most children can say eight to ten words. By two years, most children are able to form simple statements, or sentences. By ages three, four and five, the number of words a child can understand quickly increases. It is at this age that children begin to understand the rules of language. Source: Voice of America
