30,000 words a day
According to a study undertaken by Infoture, children who at least 30,000 words a day from their parents and other people around are likely to excel academically as they grow up.
The study found that children who heard at least 33 million words (30,000 a day) from birth the age of 3 tend to have higher IQs at the age of 10 than those who hear fewer words. The study also found that television viewing tends to significantly decrease the amount of conversation in a home, which negatively effects children’s language and academic development.
Infoture has developed a system called LENA (Language ENvironment Analysis system) which provides parents with information about their children’s language environment such as the number of words spoken by parents and children.
