[Sorry about the ugly format but this PDF won't allow text copying. The abstract says they found that pre-literate children's "reading circuits" (previously established brain activity assoiate with reading) were activated by printing letters with pencils, but NOT when they typed the letters or traced them rather than making their own. They conclude that handwriting may encourage reading skills--by inference, typing might slow down acquisition of reading skills?]
