Résumé publicEffet de l’expertise de la frappe au clavier sur la lecture.

For a typing expert, all ten fingers are used, based on a fixed division of the left and right sides of the keyboard. Interestingly, for an expert, a word containing only alternations between the left and right hand is much easier to type than a word containing letters associated with the same hand, because skilled typists move their hands in parallel. This project aims at exploring whether this motor coordination difficulty occurring for certain words affects the reading of those same words. Presently, we already designed a set of French words where the amount of cross- and within-hand transitions was manipulated as a continuous variable. We also designed the experiment. We aim at testing whether lexical decision performance for those words and matched pseudowords showed a differential effect of the amount of cross- vs within-hand transitions in expert and non-expert typists.
