“This matters. A child who has heard 48 million words in the first three years won’t just have 3.7 times as many well-lubricated connections in its brain as a child who has heard only 13 million words. The effect on brain cells is exponential. Each brain cell can be connected to hundreds of other cells by as many as ten thousand synapses. That means children who have been exposed to extra talk have an almost incalculable cognitive advantage.”
