Abstract
Biscriptuality is the ability to write in two different scripts. Achieving handwriting expertise in a single script demands years of intensive practice, and these demands are even stronger when two scripts must be mastered. Biscriptuality could thus impact the cognitive and motor skills underlying graphomotor control. Here, we aimed at establishing that biscriptuality enhances graphomotor control, and at testing whether biscriptuals have better fine motor skills and working memory performance compared to Latin monoscriptuals.
We found that biscriptuals perform better than monoscriptuals on graphomotor tasks, and on 3 types of fine motor control tasks indexing dexterity, motor timing under spatial constraints, and spontaneous motor tempo; the two groups did not significantly differ in their working memory performance. These results demonstrate that writing expertise widely impacts the organization of the motor system.
期刊介绍：
CORTEX is an international journal devoted to the study of cognition and of the relationship between the nervous system and mental processes, particularly as these are reflected in the behaviour of patients with acquired brain lesions, normal volunteers, children with typical and atypical development, and in the activation of brain regions and systems as recorded by functional neuroimaging techniques. It was founded in 1964 by Ennio De Renzi.
