But experts on writing do not agree: pens and keyboards bring into play very different cognitive processes. “Handwriting is a complex task which requires various skills – feeling the pen and paper, moving the writing implement, and directing movement by thought,” says Edouard Gentaz, professor of developmental psychology at the University of Geneva. “Children take several years to master this precise motor exercise: you need to hold the scripting tool firmly while moving it in such a way as to leave a different mark for each letter.”
Operating a keyboard is not the same at all: all you have to do is press the right key. It is easy enough for children to learn very fast, but above all the movement is exactly the same whatever the letter. “It’s a big change,” says Roland Jouvent, head of adult psychiatry at Pitié-Salpêtrière hospital in Paris. “Handwriting is the result of a singular movement of the body, typing is not.”
