We examine scientific findings on how intelligence develops in babies.
Until recently, many people believed that babies only wanted food and to be kept warm and dry. Some even thought that babies were unable to learn anything until they were five or six months old.
However, doctors in the United States claim that babies start learning from their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to identify experiences that can promote healthy development.
Researchers at the institute have found that babies are strongly influenced by their environment. They say that a baby will smile if their mother does something that they like. Babies learn to get the best care possible by smiling to please their mother or other carer. This is how babies learn to connect with and communicate with other people.
The researchers say that this ability to learn exists even before birth. They claim that newborn babies can recognise and understand sounds that they heard while developing inside their mothers.
Another study has suggested that babies with low birth weight and no evidence of disability may be more likely than other children to experience physical and mental health issues.
American researchers studied almost five hundred boys and girls. The children were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987. At birth, each child weighed less than two thousand grams.
The children had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests at home. Their results were then compared with those of other children of the same age.
The study found that young people with low birth weight often experienced more difficulties with motor skills than others. These issues were particularly prevalent among males, individuals with damaged nerve tissue in the brain, and those who had received oxygen supplies for several days as babies.
Experts say that the first three years of a child’s life are the most critical for language and speech development. This is when the brain develops. Language and communication skills develop best in an environment rich in sounds and sights. It is also important for the child to repeatedly hear the speech and language of others.
The National Institutes of Health state that there is evidence to suggest that there are important periods of speech and language development in children. This means that the brain is best able to learn a language during these periods. Officials say that if these periods pass without early contact with a language, it will be more difficult to learn a language.
The first signs of communication occur in the first few days of life, when a baby learns that crying will result in food and attention being provided. Research shows that most children recognise the general sounds of their native language by six months of age. By that time, a baby will usually begin to make sounds. Over time, these sounds evolve into a kind of nonsense speech.
By the end of their first year, most children can say a few simple words. However, they may not understand the meaning of these words. By eighteen months of age, most children can say eight to ten words. By the age of two, most children can form simple sentences. Between the ages of three and five, the number of words a child can understand increases rapidly. It is at this age that children begin to understand the rules of language.
Many children grow up in homes where more than one language is spoken. Clearly, understanding two languages can be helpful as children grow older. However, new studies are showing the more immediate effects of bilingualism on babies’ brains.
One of these studies was organised by researchers at the University of Washington. They measured brain activity in order to compare babies from bilingual families with those from monolingual families. The information gathered is helping to explain how the developing brain processes language and how this process can influence brain development.
The researchers studied babies aged six to twelve months. None of the babies were yet saying words in any language. Even the youngest monolingual babies could recognise a difference between the language spoken at home and another language. However, by the age of ten to twelve months, the monolingual babies could no longer identify the sounds of a second language, only the main language spoken in their home.
By contrast, the bilingual babies did not differentiate between the sounds of different languages spoken to them between six and nine months of age. However, between ten and twelve months, they could identify the different sounds of both languages.
Another report suggests that the effects that languages have on young brains are a result of human speech, rather than video or audio recordings. In fact, the American Academy of Pediatrics advises parents of young children to limit their youngsters’ screen time. The group states that watching television offers no educational benefit to children under two years old.
Many videos are specially created for young children. They are advertised as educational tools. However, the American Academy of Pediatrics says there is little evidence that such videos have any beneficial effect on babies. In fact, the group is warning that spending too much time in front of television screens can slow language development in children. It therefore suggests that parents limit the time babies spend watching screens, including those on televisions and computers.
This recommendation was published last month at a meeting of the Academy. This warning is less severe than one the Academy made in 1999. At that time, parents were advised to completely avoid television viewing for children under two years old.
The group now recognises that banning all screen time is probably unrealistic in an age where video technology is ubiquitous. It says that what is more helpful for the development of young children is communication and activities with people. The AAP says that having the television on, even if young children are not watching it directly, can cause problems.
Another American study has shown the effect of early education on future learning abilities. The study followed over one thousand three hundred children from birth until they were ten or eleven years old. It found that children who received higher-quality care before starting school had better language skills by that age than children who received lower-quality care.
This study is known as the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. It is said to be the largest and longest-running study of childcare in the United States.
The children included in the study were born around 1991 in ten different areas of the country. Researchers examined the quality and quantity of childcare that the children received until they were four and a half years old. Childcare was defined as any care provided by people other than the child’s mother for at least ten hours a week. This included care provided by fathers or other family members.
The researchers then assessed each child’s academic performance and social development. They also considered other factors, such as the quality of classroom education and parenting.
They examined whether developmental qualities observed in young children were still present a few years later. They found that older children who had received higher-quality childcare continued to perform better in language skills tests.
The researchers tested the children’s ability to name objects shown in a series of pictures. The study confirmed that the link between high-quality childcare and better test results persisted as the children grew older. It also found that the children’s ability was not dependent on how long they had spent in childcare.
