“developmental and cognitive psychologists find further evidence that language acquisition is ‘usage-based’. In this view, language acquisition is possible because of children’s general cognitive capacities and the vast number of opportunities they have to make connections between the language they hear and what they experience in their environment. Sophisticated electronic recording devices have been used to track and count words and phrases children hear in their daily lives. Deb Roy documented his son’s acquisition of words, showing the frequency and the contexts for the occurrence of language. Most remarkable, perhaps, is the demonstration of the power of interaction between the child and the adults and how adults focus on the language the child has begun to use (Roy 2009).”
